1.0 INTRODUCTION
1.1 Site Description
Site Name Proposed TOSA Village on Indiana Avenue
Site Location/Address 1850 West Indiana Avenue, Salt Lake City, Utah
Site Description
The site consists of Parcel No. 15-10-101-001 totaling 45.13 acres and a
portion of Parcel No. 15-03-351-003 of approximately 8.5 acres. The site
has historically been used as a municipal landfill and as a green waste
repository.
Exhibit 1 (Appendix A) is a site diagram indicating the approximate locations of the site
investigation areas and sample locations in relation to pertinent site features.
1.2 Project Information
TOSA is interested in developing the eastern portion of the site with tiny homes, several larger
community buildings, open air pavilions, roadways and a parking lot. The west side of the property
may be used at a later date for outdoor uses, such as a park, playgrounds or gardening areas, if
determined to be suitable for such uses. In addition, TOSA is interested in learning if the soil
placed on top of the landfill debris on the west side of the site would be suitable for use as fill in
other parts of the site, specifically the low area on the east side of the property.
An LSI conducted by Terracon (report dated July 1, 2021, Terracon Project No. 61217255 Task
1) attempted to better delineate the nature and extent of landfill debris on the eastern portion of
the site. Observations made during the excavation of 17 test pits at the site indicate approximately
one third of the site has received little or no landfill debris. The remaining areas are covered
either by the large landfill pile or fill ranging from 2.5 to 7 feet thick. While measurements made
at the site with direct-reading instruments did not suggest landfill gases are being generated in
significant amounts, Terracon recommended soil gas samples be collected and analyzed for
methane and volatile organic compounds (VOCs).
Additionally, a drainage ditch running through the approximate center of the site was observed to
be stained with possible petroleum hydrocarbon or other suspect deposits. Terracon
recommended collecting samples along the ditch to investigate the possible presence of
contaminants in sediments and shallow soils within the ditch.

1.3 Objectives
The Supplemental Limited Site Investigation (LSI) was designed to evaluate the presence of
VOCs and methane in soil gas, with an emphasis on areas where larger community buildings
would be sited, and the presence of typical industrial contaminants in sediments and shallow soils
along the ditch in areas where surficial staining has been observed.
1.4 Standard of Care

2.0 LIMITED SITE INVESTIGATION METHODOLOGIES
2.1 Utility Clearance
Prior to conducting the subsurface investigation, the public utility locating service (Blue Stakes)
was notified to arrange for underground utility locates at the above-referenced site.
2.2 Soil Gas Samples
Soil gas samples were collected August 4, 2021. Prior to sampling, five soil gas implants (SG-1
through SG-5) were installed at the site on July 30, 2021. Three of the implants were positioned
toward the southern end of the property in areas where the proposed development includes
community buildings (SG-1, SG-2, and SG-3). The two remaining implants were positioned
centrally and toward the north end where general residential structures are planned (SG-4 and
SG-5). Soil gas sample locations are shown on the Site Diagram Exhibit 1 (Appendix A).
The soil gas implants were installed using a direct-push drill rig to advance a boring to an
approximate depth of 4 to 6 feet bgs. The implants consist of a 6-inch long stainless steel
disposable screen anchored to a polyethylene tubing that extends to the surface. A one-foot sand
pack, created of 10-20 silica sand, was placed around the implant and the remainder of the anulus
was filled with hydrated bentonite chips. Care was taken to ensure adequate hydration of the
chips to avoid air flow through the bentonite which might dilute the soil gas sample.
The soil gas implants were allowed to equilibrate for twenty-four hours before sampling. In
addition, due to heavy rains following the installation of the implants, sampling was delayed three
additional days to ensure soils were not saturated. Prior to sample collection, Terracon conducted
leak detection tests at each sample location. The first test was to evaluate the sample train for
leaks by conducting a shut-in test on the sample train after it was fully assembled. The shut-in
test was conducted by closing the valve to the vapor point and applying a vacuum to the closed
sample train while monitoring the pressure on an inline vacuum gauge for one minute. If the
sample train held a constant vacuum pressure, the sample train was deemed to be airtight.
Following the shut-in test, the air that was evacuated from the sample train to generate the
vacuum was purged.
A second leak detection test was conducted by introducing helium gas at a concentration between
15 and 20 percent into a sampling shroud placed over the probe. If helium was measured in the
sampling train at a concentration of greater than 7,500 parts per million (ppm), it indicated there
was potential breakthrough in the sampling train and all connections were re-examined and
tightened where necessary and re-tested. Three helium tests were conducted at each location
prior to sampling.

The five soil gas samples were collected in laboratory-supplied, batch certified clean 400-mL
Summa® canisters, using new Teflon® tubing and a flow regulator that restricts flow to no more
200 mL per minute.
2.3 Shallow Soil Samples in North Ditch
Shallow soil samples along the North Ditch were collected on July 30, 2021. Sample locations
were selected based on the presence of staining and on topographically low points along the ditch
where runoff and/or discharge would be expected to pond. The shallow soil sample locations are
shown on the Site Diagram (Exhibit 1, Appendix A).
Shallow soil samples were collected from the sediments and surficial soils from 0 to 4 inches
below the surface using a hand trowel. Sampling equipment was cleaned using an Alconoxâ
wash and potable water rinse before beginning the project and before collecting each soil sample.
The shallow soil samples were placed in laboratory-prepared containers, labeled, and placed on
ice in a cooler. The samples and completed chain-of-custody documentation were subsequently
shipped via FedEx overnight to Pace National Analytical Laboratories, a Utah-certified laboratory,
for analysis on a standard turnaround.
3.0 LABORATORY ANALYTICAL PROGRAM
The soil gas samples were analyzed for volatile organic compounds (VOCs) using EPA Method
TO-15 and Methane using EPA Method 8015M.
The shallow soil samples were analyzed for constituents commonly associated with industrial
uses:
§Polycyclic aromatic hydrocarbons (PAHs) using EPA Method 8021
§Volatile Organic Compounds (VOCs) using EPA Method 8260;
§Pesticides and PCBs, using EPA Methods 8081/8082;
§RCRA 8 Metals (arsenic, barium, cadmium, chromium, lead, selenium, silver and
mercury) using EPA Methods 6010 and 7000.
4.0 RESULTS
Exhibit 1 (Appendix A) shows the locations of the shallow soil and soil gas samples as well as
pertinent site features, specifically the North Ditch.
4.1 Soil Gas Sample Results
The analytical results for VOCs and methane in soil gas are summarized in Table 1 (Appendix
B). Only compounds which were detected in at least one sample are displayed in the table. The
Supplemental Limited Site Investigation

August 26, 2021■Terracon Project No. 61217255_2
Responsive ■Resourceful ■Reliable 5
laboratory analytical report with the full list of analytes and chain of custody are presented in
Appendix C. The analytical results were compared to the U.S. EPA’s Target Sub-Slab and Near-
source Soil Gas Concentration Vapor Intrusion Screening Levels (VISLs) for residential and
commercial scenarios. The VISLs use a Target Cancer Risk of 1x10-6 (one-in-a-million) and a
Hazard Quotient of 1.
As shown in Table 1 (Appendix B), several VOC compounds were detected in the five samples.
Benzene exceeded the residential VISL in the sample from SG-3 and chloroform exceeded the
residential VISL in the sample from SG-4. No sample exceeded a commercial VISL.
EPA has not established a VISL for methane; however, the Lower Explosive Limit (LEL) is used
to evaluate the physical hazard posed by methane, due to its explosive characteristic. The LEL
for methane is 5 percent which is equivalent to 50,000 parts per million by volume (ppmv). The
soil gas sample from SG-3 reported a methane concentration of 23,000 ppmv which is
approximately one half of the LEL.
4.2 Soil Sample Results
The analytical results for the three North Ditch surface soil samples are summarized in Table 2
(Appendix B). Only compounds which were detected in at least one sample are displayed in the
table. The laboratory analytical report and chain of custody are presented in Appendix C. The
analytical results were compared to the U.S. Environmental Protection Agency’s (EPA’s) Regional
Screening Levels (RSLs) for soil under both residential and commercial scenarios. The RSLs use
a Target Cancer Risk of 1x10-6 (one-in-a-million) and a Hazard Quotient of 1.
As shown in Table 2, lead was reported at 548 milligrams per kilogram (mg/kg) in the sample ND-
03. This exceeds the RSL for residential properties of 400 mg/kg. The polycyclic aromatic
hydrocarbon, benzo(a)pyrene was also reported above the residential RSL in the sample from
ND-02. It was reported at 0.466 mg/kg compared to the residential RSL of 0.11 mg/kg. Neither
of these compounds exceed the commercial RSL.
Arsenic was reported in all three samples at concentrations ranging from 18.1 to 24.6 mg/kg. This
exceeds both the residential and commercial VISLs of 0.68 and 3 mg/kg, respectively.
5.0 CONCLUSIONS AND RECOMMENDATIONS
5.1 Summary of Soil Sample Results
Lead and arsenic were the only two metals analyzed that exceeded the U.S. EPA’s residential
RSLs. Lead exceeding the residential RSL was present in one of the three soil samples. Although
arsenic is also reported at concentrations that exceed the RSLs, the concentrations are consistent

with what is generally considered naturally occurring background levels for the Salt Lake Valley
and is less than cleanup levels generally accepted by the DEQ.
PAH-impacted soils exceeding the U.S. EPA’s residential RSLs were reported in one soil sample
at a concentration that exceeds the residential RSL. PAHs and lead have not been observed
widely across the site, suggesting these are limited occurrences.
5.2 Summary of Soil Gas Sample Results
Several VOC compounds were reported in one or more of the three soil gas samples. Benzene
was reported in the soil gas sample from SG-3 in the southern area of the site at a concentration
that exceeds its residential VISL, and chloroform exceeded the residential VISL in the sample
from SG-4. None of the other reported constituents exceeded the residential VISLs. The
occurrence of low concentrations of two VOCs in two of the five soil gas samples suggest a vapor
intrusion condition may exist at the site.
One of the five soil gas samples reported an elevated concentration of methane (approximately
one half of the LEL). This suggests a source of methane gas is present in this area, likely a
deposit of landfill or green waste that is still decomposing.
Based on the results of this Supplemental LSI, Terracon recommends that vapor mitigation be
considered during development of larger buildings in the areas where VOCs exceeded VISLs. In
addition, limited removal of landfill and green waste in the area of elevated methane gas should
be performed. Finally, elevated concentrations of lead should be addressed through either
capping or removing impacted soils.
Terracon appreciates being of service to you on this project. If you have any questions, or require

CASE NARRATIVE
Unless qualified or notated within the narrative below, all sample aliquots were received at the correct
temperature, in the proper containers, with the appropriate preservatives, and within method specified
holding times. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental
samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality
Control are within established criteria except where addressed in this case narrative, a
non-conformance form or properly qualified within the sample results. By my digital signature below, I
affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the
potential to affect the quality of the data have been identified by the laboratory, and no information or
data have been knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
(dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry)Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry)Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
B The same analyte is found in the associated blank.
J The identification of the analyte is acceptable; the reported value is an estimate.
J3 The associated batch QC was outside the established quality control range for precision.
J4 The associated batch QC was outside the established quality control range for accuracy.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
P RPD between the primary and confirmatory analysis exceeded 40%.
V The sample concentration is too high to evaluate accurate spike recoveries.

1.0 INTRODUCTION
1.1 Site Description
Site Name Proposed TOSA Village – Pilot Phase
Site Location/Address 1850 West, Salt Lake City, Utah
General Site Description
The Site is an approximately 8-acre parcel of land within an
approximately 45-acre parcel owned by Salt Lake City Corporation,
that is used for managing the city’s green waste. The Site is
unimproved with the exception of an approximately half-acre
asphalt pad at the south end of the site. A sewer main line runs
south to north, roughly along the Site’s west boundary. The North
Drain, a stormwater management feature, crosses diagonally
through the north end of the site. The site is bound to the east by
Tear-Apart Auto Recycling and by the Alvie Carter Trust property.
The Alvie Carter Trust property has been used for auto wrecking
and miscellaneous storage and the property owner has allowed
significant volumes of debris to encroach onto the Site. The
southern boundary is formed by Indiana Avenue; the north and west
adjoining properties are the remainder of the parent parcel.
Exhibit 1 (Appendix A) presents the site location on a portion of the USGS 7.5-minute series
topographic map.Exhibit 2 (Appendix A) is a site diagram that indicates the approximate
locations of the sampling points in relation to pertinent site features.Exhibit 3 (Appendix A)
shows the sampling point locations relative to proposed development features.
1.2 Project Background
Terracon has completed screening-level investigations of the larger parent parcel to assess
general impacts from historical landfilling activities at the site, with the objective of understanding
its potential to be developed as a tiny home village (Limited Site Investigation, report dated July
1, 2021, analytical data provided separately July 9, 2021, Terracon Project No. 61217255 and
Supplemental Limited Site Investigation, report dated August 26, 2021, Terracon Project No.
61217255_2). TOSA has identified approximately 8 acres at the southeast corner of the property
for a potential pilot scale development and desires to better understand the existing environmental
impacts, if any. Additionally, TOSA, in partnership with the property owner, Salt Lake City
Corporation, intends to seek regulatory oversight from the UDEQ to guide any necessary
remediation to ensure the site can be appropriately developed for residential use.

1.3 Objectives
The objective of this LSI was to evaluate groundwater, soils, and soil gas for the presence of
contaminants commonly associated with landfill and industrial properties at concentrations above
regulatory screening levels.
1.4 Standard of Care
Terracon’s services were performed in a manner consistent with generally accepted practices of
the profession undertaken in similar studies in the same geographical area during the same time
period. Please note that Terracon does not warrant the work of laboratories, regulatory agencies
or other third parties supplying information used in the preparation of the report. These LSI
services were performed in accordance with the scope of work agreed with you, our client, as
reflected in our proposal, and were not restricted by ASTM E1903-19.
1.5 Additional Scope Limitations
Findings, conclusions, and recommendations resulting from these services are based upon
information derived from the onsite activities and other services performed under this scope of
work. Such information is subject to change over time. Certain indicators of the presence of
hazardous substances, petroleum products, or other constituents may have been latent,
inaccessible, unobservable, non-detectable or not present during these services, and we cannot
represent that the site contains no hazardous substances, toxic materials, petroleum products, or
other latent conditions beyond those identified during this LSI. Subsurface conditions may vary
from those encountered at specific borings or wells or during other surveys, tests, assessments,
investigations or exploratory services; the data, interpretations, findings, and our
recommendations are based solely upon data obtained at the time and within the scope of these
services.
1.6 Reliance
This LSI report has been prepared for the exclusive use and reliance of The Other Side Academy.
Use or reliance by any other party is prohibited without the written authorization of The Other Side
Academy and Terracon. Reliance on the LSI report by the client and all authorized parties will be
subject to the terms, conditions and limitations stated in the proposal, LSI report, and Terracon’s
Agreement. The limitation of liability defined in the Agreement is the aggregate limit of Terracon’s
liability to the client and all relying parties.
2.0 SCOPE OF WORK
The approved scope of work for this LSI consisted of the following:
Limited Site Investigation Report
Proposed TOSA Village Pilot Phase ■ Salt Lake City, Utah
March 2, 2022 ■ Terracon Project No. 61217255 Task 3
Responsive ■ Resourceful ■ Reliable 3
n Excavate twelve test pits for the purpose of collecting soil samples, and up to four
additional test pits for observation only.
n Install 4 soil gas probes and collect soil gas samples from these probes and one previously
installed probe;
n Install 2 monitoring wells and collect groundwater samples from the 2 wells and an existing
onsite well;
n Survey three monitoring wells to measure site- specific direction of groundwater flow;
n Collect 2 surface soil / sediment samples from the North Drain
Due to field conditions or other specific factors, modifications to the scope of work were made.
The existing monitoring well at the southern end of the site was examined using a water level
probe and was found to be dry. As a result, a new monitoring well was installed approximately
20 feet to the north as a replacement. This well was developed, surveyed, and sampled, along
with the other two new monitoring wells. In addition, soil gas probe SG-1, installed during the
previous LSI in August 2021, could not be located due to the presence of snow cover at the time
of the field activities. A new probe was installed as a replacement approximately 10 feet to the
south of the original probe. and was sampled along with the other soil gas probes. During the soil
gas probe sampling activity, SG-6 was found to be in contact with groundwater and could not be
sampled. Finally, during the period of field activities, there was a significant amount of standing
water along the course of the north drain, making it difficult to determine its actual alignment. It
was decided that the drain samples should be collected during a dryer period so that the sample
results would reflect the conditions within the actual banks of the ditch.
3.0 METHODOLOGY
Prior to sampling, the public utility location service (Blue Stakes) was notified at least 48 hours
prior to digging or drilling as required by law. Field activities were conducted from December 22,
2021 through January 26, 2022, and consisted of the following activities:
n Excavation of test pits for collecting soil samples (TP-17 through TP-20; TP-22 through
TP-24; TP-26 -28; TP-30-32);
n Excavation of test pits for observation only (TP-21, -25, and -29);
n Installation of five soil gas probes (SG-1, SG-6, SG-7, SG-8, and SG-9);
n Installation, development and sampling of three monitoring wells (TOSA MW-1 through
TOSA MW-3); and
n Sampling of four soil gas probes (SG-1, SG-7, SG-8, and SG-9).
Sample locations are shown on Exhibit 2 in Appendix A. Details of each activity are presented
in the following sections.

3.1 Test Pits for Soil Logging and Sampling
Terracon’s field activities were conducted on January 13, 2022, by Ms. Nancy Saunders, Terracon
Project Manager. The work consisted of excavating a total of fifteen test pits. Soil samples were
collected from twelve of the test pits; the remaining three test pits were used for observation and
soil logging. Subcontracted excavation services were performed EK Bailey Construction. The
test pit locations are shown on the Site Diagram (Exhibit 2, Appendix A).
Soils from the test pits were logged to document general lithology, color, and the presence or
absence of fill and debris. In addition, the test pits were field screened using a photoionization
detector (PID) to qualitatively evaluate the presence of volatile organic compounds (VOCs); a
direct-reading methane detector capable of reading methane in the parts per million (ppm) range,
a hydrogen sulfide gas detector, and a combustible gas indicator to monitor the risk of explosion.
Copies of the test pit logs are presented in Appendix C.
Samples were collected from the upper 0 – 12 inches of native material. In several cases where
no fill was encountered, samples were collected from 12 – 30 inches below ground surface to
avoid introducing potential contaminants from foot traffic and the backhoe into the sample,
providing there was no evidence of impacts in the surface soils.
Soil samples were collected from the excavated material using a hand trowel. The samples were
placed in laboratory-prepared containers, labeled, and placed on ice in a cooler. The sample
coolers and completed chain-of-custody forms were relinquished to Pace Analytical National
Center for Testing & Innovation (Pace), a Utah-certified laboratory, for analysis on a standard
turnaround time.
Sampling equipment was cleaned using an Alconoxâ wash and potable water before beginning
the project and before collecting each soil sample.
3.2 Monitoring Well Installation, Development, and Sampling
3.2.1 Soil Borings for Monitoring Wells
Soil borings for monitoring wells were advanced with direct push (“Geoprobe”) drilling equipment
outfitted with 3.75-inch rods to allow for the construction of 2-inch-diameter monitoring wells. The
mechanized drilling services were performed by a Utah-licensed well driller, Direct Push Services;
Terracon environmental personnel selected the boring locations, visually observed the drilling
activities, logged the soil borings, and collected field samples.
During advancement of the soil borings, soils were continuously cored in 5-foot intervals and
observed to document subsurface soil types, color, relative moisture content, and sensory
evidence of environmental impacts. The soil cores were also field screened using sensory

methods, a photoionization detector (PID) to qualitatively evaluate the presence of volatile organic
compounds (VOCs), a direct reading methane detector, and a hydrogen sulfide gas detector.
3.2.2 Well Installation
After all the borings had been advanced they were converted to groundwater monitoring wells
(TOSA MW-1, TOSA MW-2, and TOSA MW-3). The monitoring wells were installed according to
the following general procedures:
n Borings were advanced to a total depth of 13 to 16.5 feet below ground surface (bgs);
n Installation of 10 feet of 2-inch diameter, 0.010-inch machine slotted polyvinyl chloride
(PVC) well screen with a threaded bottom cap;
n Installation of 2-inch diameter, threaded, flush-joint PVC riser pipe to approximately 2 feet
above the surface;
n Addition of pre-sieved 20/40 grade silica sand for annular sand pack around the screened
interval from the bottom of the boring to 2 feet above the top of the screen;
n Placement of 2 feet of hydrated bentonite pellets above the sand pack; and
n Addition of cement/bentonite slurry to the surface;
Copies of the boring logs with monitoring well construction details are presented in Appendix C.
3.2.3 Well Development
At least 24 hours after the wells were constructed, they were developed by bailing with new
disposable bailers to remove fine grained sediments from the sand pack and well screen in order
to allow the infiltration of formation water. Approximately five casing volumes of water were
removed from each well.
3.2.4 Well Survey
The top of the PVC casing in each of the three monitoring wells was surveyed on January 29,
2022, relative to an arbitrary datum point of 100 feet. Depth-to-groundwater was measured in
each of the monitoring wells on January 26, 2022. The site-specific groundwater gradient was
calculated using the well casing elevations and depth-to-groundwater measurements.Table 1
(Appendix B), is a summary of the survey and depth-to-groundwater measurement data. The
site-specific groundwater gradient is shown on Exhibit 2 (Appendix A).
3.2.5 Groundwater Sampling
The wells were sampled on January 26, 2022, using low-flow sampling methods. The wells were
evacuated with a low-flow peristaltic pump. New high-density polyethylene (HDPE) tubing was
used for each well, the inlet of which was placed within the top foot of the water column. Water
quality parameters (pH, temperature, conductivity, and dissolved oxygen) were measured in line
Limited Site Investigation Report

Responsive ■ Resourceful ■ Reliable 6
with a YSI Professional Plus flow-through cell, calibrated prior to use according to manufacturer's
specifications. Using depth to water and total depth of well measurements, the casing volume of
water for each well was calculated. The peristaltic pump was set to pump water at a rate of 200
milliliters per minute (mL/min) or less. The wells were purged until one of the following criteria
were met:
n groundwater quality parameters of pH, temperature, conductivity, and dissolved oxygen
readings had stabilized to within 10% over three consecutive readings;
n three casing volumes were removed; or
n the well had pumped dry.
The scope of work included collecting groundwater samples for analysis of perfluoroalkyl
substances (PFAS). These analytes require special sampling and handling methods. Terracon
employed the “Clean Hands – Dirty Hands” protocol, developed by the US EPA for sampling low
level metals and can be used for other contaminants that are analyzed in the parts per trillion
range. In this procedure, one field person is designated as the “clean hands” sampler and is
assigned with only handling and filling the sample containers. A second field person is designated
as the “dirty hands” sampler and performs all other tasks, such as opening the well covers,
measuring depth to water, and installing the tubing in the well. To verify the field methods were
protective of sample integrity, a field blank and an equipment blank were collected. The results
of the blank analytical results are discussed in Section 5, Quality Assurance / Quality Control.
Once the sample containers for PFAS were filled and placed in their own cooler, the remainder of
the sample containers were filled according to Terracon’s Standard Operating Procedures. For
all wells sampled, using the well purging pump already in place, the sample containers were filled
out of the pump discharge line maintaining the low-flow setting. Samples for analysis of metals
were filtered through an in-line, disposable, 0.45-micron pore filter.
The use of non-disposable sampling equipment was limited to the water level probe. It was
decontaminated using an Alconox® detergent wash followed by a potable water rinse then
followed by a certified PFAS-free water rinse, prior to commencement of the project and between
the collection of each sample.
3.3 Soil Gas Sampling
3.3.1 Probe Installation
Soil gas probes were installed December 22, 2021, at the locations shown on Exhibit 2
(Appendix A). The soil gas sampling probes were installed using a direct-push drill rig to advance
a boring to an approximate depth of 4 to 5 feet bgs. The implants consist of a 6-inch long stainless
steel disposable screen anchored to a polyethylene tubing that extends to the surface. A one-
foot sand pack, created of 10-20 silica sand, was placed around the implant and the remainder of

the anulus was filled with hydrated bentonite chips. Care was taken to ensure adequate hydration
of the chips to avoid air flow through the bentonite.
3.3.2 Soil Gas Sample Collection
The samples were collected on January 26, 2022. As noted in Section 2, SG-6 was apparently
set in or near the water table and could not be sampled. The remaining soil gas probes were
sampled according to the following methodology. At each location, Terracon conducted leak
detection tests. The first test was to evaluate the sample train for leaks by conducting a shut-in
test on the sample train after it was fully assembled. The shut-in test was conducted by closing
the valve to the soil gas probe and applying a vacuum to the closed sample train while monitoring
the pressure on an inline vacuum gauge for 1 minute. If the sample train held a constant vacuum
pressure, the sample train was deemed to be airtight. Following the shut-in test, the air that was
evacuated from the sample train to generate the vacuum was purged.
A second leak detection test was conducted by introducing helium gas at a concentration between
15 and 20 percent into a sampling shroud placed over the probe. If helium was measured in the
sampling train at a concentration of greater than 7,500 parts per million (ppm), it indicated there
was potential breakthrough in the sampling train and all connections were re-examined and
tightened where necessary and re-tested. Three helium tests were conducted at each location
prior to sampling.
The soil gas samples were collected in laboratory-supplied, batch certified clean 400-mL Summa®
canisters, using new Teflon® tubing and a flow regulator that restricts flow to no more 200 mL per
minute.
The Summa canisters were then packaged and shipped to the analytical laboratory under chain
of custody.

4.0 RESULTS
4.1 Subsurface Conditions
Apparent fill material with debris was encountered in test pits TP-22, -24, -25, -28, and -31. The
fill consisted of dark brown silt mixed with bits of wood, bricks, and concrete. In test pit TP-22,
the wood fragments appeared charred. The observed thickness of the fill ranged from 1.5 feet
thick in TP-24 to 5 feet thick in TP-22 and TP-25. It should be noted that several test pits
excavated in the area for previous investigations also encountered fill with debris. These are TP-
11R, TP-12, and TP13 and are included on Exhibits 2 and 3; Appendix A.
Below the fill material, sediments consisted of silty and clayey sand. In borings for MW-1 and
MW-3 and TP-21, clay was encountered below the silty and clayey sand layer. No positive
detections for methane, hydrogen sulfide, or VOCs were measured with the direct-reading
instruments.
The depth to groundwater varied greatly across the site and was encountered at approximately
2.5 feet below ground surface at the southern end of the property (TP-32 and MW-3) and as much
8 feet bgs in MW-2, and 7 feet bgs in test pits TP-18, -19, and -25. However, based on elevation
data provided by the Client’s ALTA survey, there is approximately 5 feet of elevation difference in
ground surface at these locations.

Groundwater elevations calculated based on the top-of-casing well elevations and depth-to-
groundwater measurements indicate groundwater at the site flows to the southwest as shown on
Exhibit 2 (Appendix A).
4.2 Soil Analytical Results
Soil analytical results are summarized in Table 2 (Appendix C). For the VOC, SVOC, PCB, and
Pesticide analyses, only compounds detected in at least one sample are displayed in the table.
For a full list of analytes, refer to the laboratory analytical reports in Appendix D. The table
includes data from sample locations near the focus area that were collected during previous
investigations. The analytical results were compared to the U.S. Environmental Protection
Agency’s (EPA’s) Regional Screening Levels (RSLs) for soil under both residential and industrial
scenarios. The RSLs use a Target Cancer Risk of 1x10-6 (one-in-a-million) and a Hazard Quotient
of 1.
As shown in the table, low levels of several VOCs and SVOCs were reported in some of the
samples; however, no compounds were detected at concentrations above regulatory screening
levels. PCBs and pesticides were not detected.
The analytical results for the 8 Resource Conservation and Recovery Act (RCRA) metals (arsenic,
barium, cadmium, chromium, lead, mercury, selenium, and silver) and hexavalent chrome show
the only occurrence of these contaminants above a screening level is from arsenic. Arsenic
concentrations exceeded both the residential and industrial RSLs for soil in the majority of the soil
samples.
4.3 Groundwater Analytical Results
Groundwater analytical results are summarized in Table 3. Screening levels used for comparison
are discussed below.
4.3.1 Groundwater Analytical Results – Dissolved Metals
The analytical results for dissolved metals (8 RCRA metals in monitoring wells TOSA MS-01, -
02, and -03 are presented in Table 3 (Appendix C). The analytical results were compared to the
U.S. EPA’s Maximum Contaminant Levels (MCLs) for drinking water.
Arsenic was the only metal to exceed the MCL. It is above the MCL of 0.010 mg/L in the samples
from TOSA MW-02 and TOSA MW-03.
4.3.2 Groundwater Analytical Results – Pesticides, PCBs, VOCs, and PAHs
For the VOC, SVOC, PCB, and Pesticide analyses, only compounds detected in at least one
sample are displayed in the table. For a full list of analytes, refer to the laboratory analytical

reports in Appendix D. Detected compounds were compared to EPA’s MCLs. In addition,
petroleum hydrocarbon results (i.e., TPH-GRO, Oil & Grease, and the VOCs methyl-tert-butyl
ether, benzene, toluene, ethylbenzene, xylenes, and naphthalene [MBTEXN]) were compared to
Utah DEQ’s ISLs. Finally, the U.S. EPA’s Vapor Intrusion Screening Levels (VISLs) are
presented for comparison. VISLs were reviewed for residential scenarios using a Target Cancer
Risk of 1x10-6 (one-in-a-million) and a Hazard Quotient of 1.
Only Methyl-tert-butyl ether (MTBE) was detected above the laboratory reporting limit. It was not
reported at a concentration that exceeds a screening level.
4.3.3 Groundwater Analytical Results - PFAS
Currently, PFAS compounds in groundwater do not have enforceable screening levels. However,
the EPA has published Health Advisory Standards (HAS) for the PFAS compounds
Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA) in drinking water of 70
nanograms per liter (ng/L). The results of the PFOS and PFOA analyses are listed in Table 3.
The full list of PFAS compounds included in the analysis (EPA Method 537 Modified for PFAS) is
presented in the laboratory analytical report (Appendix D).
As shown in the table, PFOA was reported at 194 ng/L in the sample from TOSA MW-02 which
exceeds the HAS of 70 ng/L. Other PFAS compounds were detected above the laboratory
reporting limits and are listed in the laboratory analytical report; however, as noted earlier, there
is currently no enforceable standard or screening level for comparison.
4.4 Soil Gas Analytical Results
The analytical results for VOCs in soil gas are presented in Table 4 (Appendix C). The results
were compared to the U.S. EPA’s Target Sub-Slab and Near-source Soil Gas Concentration
VISLs for residential scenarios. The VISLs use a Target Cancer Risk of 1x10-6 (one-in-a-million)
and a Hazard Quotient of 1.
As shown in Table 4 (Appendix C), benzene and chloroform were reported at concentrations
exceeding the residential VISLs. Chloroform was reported at 8.4 micrograms per cubic meter
(ug/m3) in SG-8 and at 73 ug/m3 in SG-9. The residential VISL is 4.07 ug/m3. Benzene was not
detected in the soil gas samples collected during this investigation; however, in August 2021, the
sample from SG-3, located west of the Pilot Phase area, reported 42 ug/m3 benzene which
exceeds the residential VISL of 12 ug/m3.
5.0 QUALITY ASSURANCE / QUALITY CONTROL
Quality control for the sampling program included using standardized sample collection and
handling methods, documenting pertinent field information, and keeping chain-of-custody

records. All sampling was conducted following Terracon’s Standard Operating Procedures
(SOPs).
The sampling work included the collection of 12 soil samples, three groundwater samples, and
four soil gas samples. Documentation provided with the laboratory analytical results reports
included case narratives; analytical data with minimum method detection limits (MDLs) and
reported detection limits (RDLs) listed for all analyses; surrogate recoveries for GC/MS analyses
with laboratory control limits; chain-of-custody records; and a quality control summary, including
method blanks, matrix spike/matrix spike duplicates (MS/MSD) with control limits, laboratory
control samples and duplicates (LCS/LCSD) with control limits; and application of data qualifiers
where warranted. Soil and groundwater sample analyses were conducted by Pace Analytical
Laboratories. Soil gas samples were analyzed by H&P Mobile Geochemistry Inc. Soil gas and
PFAS samples did not have associated MS/MSDs analyzed, but did have LCS/LSCD, surrogate
recoveries, and method blanks analyzed.
Assessment of the Data Quality Indicators (DQIs) for Precision, Bias and Accuracy,
Representativeness, Comparability, Completeness, and Sensitivity are presented in the following
subsections.
5.1 Precision
Precision was evaluated on the basis of relative percent difference (RPD) as a measure of
reproducibility between LCS/LCSD pairs and MS/MSD pairs (analytical precision) and between
field samples and field duplicate samples (field precision).
The RPD is calculated to evaluate precision using the following equation.

used to qualify this data. The affected analytes were not detected in concentrations
above the RDL or applicable regulatory screening levels. It is not anticipated the
analytical precision issue will affect the conclusions of this report and those
samples are well below applicable screening levels.
¡The laboratory noted that the RPDs between the primary and confirmatory analysis
for the MS and MSDs for most pesticides (Batch W1804715) and PCB 1016 and
PCB 1260 (Batch WG1804715) exceeded 40%. A P flag was used to qualify this
data. The affected analytes were not detected in concentrations above the RDL
or applicable regulatory screening levels. It is not anticipated the analytical
precision issue will affect the conclusions of this report and those samples are well
below applicable screening levels.

Based on the results of the RPD analyses of the LCS/LCSD pairs and the evaluation provided
above,analytical precision is considered within control for Laboratory Set 222013172 (Soil
Gas Samples).
5.1.2 Field Precision
Field duplicates were collected at rate of 10 percent of soil, groundwater, and soil gas samples
(or one field duplicate for up to 10 samples of each of these media). Two field duplicate soil
samples and one field duplicate groundwater sample and one field duplicate soil gas sample were
selected at random.
Analytical results for original samples and field duplicate pairs that are less than five times the
laboratory’s Reported Detection Limit (RDL) in the analytical reports were considered within
control if the difference between the sample concentration and its duplicate was less than two
times the RDL. When analytical results for the original sample and the field duplicate pairs are
greater than five times the RDL, the duplicate pair was considered within control when the RPDs
for the field duplicate pairs were within the control limits (50% for solid samples and 25% for
groundwater samples).
n Laboratory Set L1456323 (Soil Samples):
¡8 RCRA Metals in Soil
Reported concentrations for arsenic for TP-28 2.5’ were less than 5 X RDL where
the duplicate, TP-280 2-5’, was greater than 5 x RDL. The difference between the
sample and duplicate concentrations was greater than 2 X RDL, so this pair is not
considered within control. The calculated RPDs for chromium and lead (67% and
74.7%, respectively), are greater than the 50% control limits. There is no regulatory
screening level for chromium, and both samples are well below any regulatory
screening level for lead. Additionally, all metals for the other duplicate pair (TP-23
1.5’ and TP-230 1.5’), are within control. It is unlikely that this original pair not
being in control had an effect on the conclusions of this report.
¡Hexavalent Chromium in Soil
The duplicate pair is considered within control as all of the analytes achieve the
requirements set out in the SOPs.

5.2 Bias and Accuracy
Bias and Accuracy were evaluated through a review of the method blanks, trip blanks, percent
recoveries for LCS/LCSD, and percent recoveries for MS/MSD summaries provided by the
laboratory. Method blanks and trip blanks were considered within control (i.e.,accuracy) if the
constituents analyzed were less than the analytical method reporting limits. LCS/LCSD and
MS/MSD analyses were considered within control if the percent recoveries were within the
laboratory’s established limits (i.e.,bias). A summary of the Quality Control assessment for Bias
and Accuracy is presented below.

A J4 value was assigned to this data. However, no samples had detections of this
analyte above the RDL or applicable regulatory screening levels. As such, the
percent recoveries for this analyte being outside of the laboratory’s control limits is
not anticipated to affect the usability of the data.
¡Bias – MS/MSD Percent Recoveries:The percent recoveries for the MS and
MSD were within the laboratory’s control limits for RCRA metals, VOCs, PAHs,

5.3 Representativeness
Representativeness is a qualitative parameter most concerned with proper design and execution
of the sampling program to produce data that accurately and precisely represent environmental
conditions. Selection of analytical methods, sampling methods and locations representative of
the media sampled were set forth in the proposal dated December 7, 2021.Representativeness
in the field was achieved by implementing the scope of work in the proposal and using appropriate
sampling methods, sample containers, sample handling and preservation methods.
Representativeness in the laboratory was achieved by using the proper analytical procedures,
meeting sample holding times, and analyzing and assessing laboratory QA/QC samples.
Field Representativeness
Sampling was conducted in general accordance with the workplan and associated Standard
Operating Procedures. The following deviations from the workplan occurred during the sampling
event.
n Sample SG-6 was not analyzed as water entered the container while attempting to
sample the soil gas.
Laboratory Representativeness
Sample analyses followed the analytical methods listed in the workplan or equivalent EPA-
approved variations of the listed methods.
n The laboratory noted that the recoveries for some extracted internal standards for the
PFAS sampling were outside the control limits for sample TOSA MW-02. The sample
was re-extracted with similar results for this extracted internal standard. Other QA/QC
parameters were within specifications. This issue is not expected to have an effect on
the usability of the data.

Representativeness is considered within control.
5.4 Comparability
Comparability is a qualitative term expressing the confidence with which one data set can be
compared to another. The comparability goal was achieved using standardized sampling
procedures in accordance with the workplan, use of standardized and approved laboratory
analytical methods, and reporting the analytical results in appropriate and consistent units.
n Sampling was conducted in general accordance with the proposal’s scope of work and
associated Standard Operating Procedures. Deviations that occurred during the
sampling event and are discussed in Section 5.3.
n Sample analyses followed the analytical methods listed in the proposal’s scope of work
or equivalent methods or EPA-approved variations of the listed methods.
n The units of measure reported by the laboratory were consistent with the units of
measure used by the regulatory screening levels.
n The number of field duplicates specified in the proposal’s scope of work was at least
10% of the field samples.
¡RCRA 8 Metals: Two field duplicate for seventeen soil samples or 11.8%, which
exceeds the 10% goal. One field duplicate for 3 groundwater samples or 33.3%,
which exceeds the 10% goal.
¡Hexavalent Chromium:One field duplicate for four soil samples or 25%, which
exceeds the 10% goal. One field duplicate for 3 groundwater samples or 33.3%,

Comparability is considered within control.
5.5 Completeness
The samples collected were submitted and analyzed by the laboratory according to the chain-of-
custody. Additionally, the data collection followed the procedures and requirements as described
in the proposal’s scope of work. The data are considered usable as qualified. The completeness
for this sampling event was 100%. Minor exceptions exist as described above, but none are
expected to affect the usability of the data or the conclusions of this report.
With acknowledgement of qualified results for the analytes listed above, the analytical data
are acceptable for their intended use to evaluate constituent concentrations compared to
applicable regulatory screening levels.
5.6 Sensitivity
Sensitivity refers to the capability of a method or instrument to discriminate between measurement
responses representing different levels of the variable of interest. The sensitivity goal is for RDLs
to be below comparative screening levels (November 2021), which vary considerably by analyte
and in value and applicability. Overall, the level of sensitivity was sufficient to allow the
identification of soil and groundwater constituents above applicable regulatory screening levels.
n Laboratory Set L1451927 (Soil Samples):
¡RCRA 8 Metals:The RDLs were all less than the EPA RSLs for analytes reported
as less than the RDL.
¡Hexavalent Chromium: The RDLs for hexavalent chromium exceeded residential
RSL. This constituent was not reported above its RDLs or MDLs in any of the
samples. As a result, this is not anticipated to affect the conclusions of this report.
¡VOCs: The RDLs were all less than the Utah ISLs, Utah Tier 1 screening levels,
and EPA residential RSLs, as applicable, for analytes reported as less than the

RDL. The only exception to this was 1,2-dibromo-3-chloropropane that had RDLs
that exceeded the EPA commercial and residential RSL. This constituent was not
reported above its RDLs or MDLs in any of the samples. As a result, this is not
anticipated to affect the conclusions of this report.
¡PAHs: The RDLs were all less than the EPA RSLs for analytes reported as less
than the RDL.
¡Pesticides and PCBs: Pesticides and PCBs were not individually analyzed for
sensitivity. However, no pesticides or PCBs were reported above RDLs or MDLs
in any of the samples. As a result, this is not anticipated to affect the conclusions
of this report.
n Laboratory Set L1455564 (Groundwater Samples):
¡RCRA 8 Metals:The RDLs were less than the regulatory screening levels for
analytes reported as less than the RDL.
¡Hexavalent Chromium: The RDLs were less than the regulatory screening levels
for analytes reported as less than the RDL.
¡VOCs: The RDLs were all less than the regulatory screening levels, as applicable,
for analytes reported as less than the RDL. The only exceptions to this were
acrolein, acrylonitrile, bromodichloromethane, carbon tetrachloride, chloroform,
1,2-dibromo-3-chloropropane, 1,2-dibromoethane, hexachloro-1,3-butadiene,
naphthalene, and vinyl chloride that had RDLs that exceeded a regulatory
screening level. As these constituents was not reported in any of the samples, it
is not anticipated to affect the conclusions of this report.
¡PAHs: The RDLs were all less than the EPA RSLs for analytes reported as less
than the RDL.
¡Pesticides and PCBs: Pesticides and PCBs were not individually analyzed for
sensitivity. However, no pesticides or PCBs were reported above RDLs or MDLs
in any of the samples. As a result, this is not anticipated to affect the conclusions
of this report.
n Laboratory Set L1456323 (PFAS Groundwater Samples):
¡PFAS:The RDLs are believed to be less than the regulatory screening levels for
analytes reported as less than the RDL.

n Laboratory Set 222013172 (Soil Gas Samples):
¡VOCs: The RDLs were all less than or equal to the EPA VISLs for analytes

Residential VISLs. The RDL did not exceed the Commercial VISL. Three samples
did have detections of chloroform above Commercial and/or Residential VISLs. It
is possible that other samples may have results also exceeding Residential VISLs
for chloroform although they are below the RDL. However, this condition is unlikely
to affect the conclusions of this report or the usability of the data.
The DQIs for Sensitivity were achieved. As such,Sensitivity was deemed acceptable.
6.0 DISCUSSION
6.1 Summary of Soil Conditions
Observations made during the excavation of 15 test pits show that much of the Site remains free
of debris-containing fill material. When encountered, primarily on the west side of the Site, the
debris consisted of wood, brick, and concrete fragments in minor amounts. Only one test pit, TP-
22, contained charred material, suggesting burning of trash was not a widespread practice.
Results of the soil sampling indicate there has been little impact from the Site’s use as a green
waste landfill and from its proximity to the historical municipal landfill on the parent parcel. Low
concentrations of benzene, xylenes, and several semi volatile organic compounds were reported
in samples across the Pilot Phase area; however, in all cases, these constituents were present
below regulatory screening levels. Pesticides and PCBs were not reported above laboratory
detection limits.
Arsenic was found at concentrations exceeding either the residential or industrial RSL, ranging
from 2.09 to 16 mg/kg. These concentrations fall within the range considered to be naturally
occurring background concentrations for Utah (as reported in Element Concentrations in Soils
and Other Surficial Materials of the Conterminous United States [U.S. Geological Survey
Professional Paper 1270; 1984]). In Terracon’s experience, cleanup levels for arsenic are
typically around 50 mg/kg for residential properties. The arsenic concentrations reported in soil
were all less than 50 mg/kg.
6.2 Summary of Groundwater Conditions
Groundwater elevation survey data were used to calculate the direction of groundwater flow. The
survey data indicate groundwater at the site is currently flowing to the southeast. There are many
potential influences on shallow groundwater in the area, including the sewer main line along the
Limited Site Investigation Report
Proposed TOSA Village Pilot Phase ■ Salt Lake City, Utah
March 2, 2022 ■ Terracon Project No. 61217255 Task 3
Responsive ■ Resourceful ■ Reliable 23
Site’s western boundary and the City Drain, approximately 1,000 feet south of the Site.
Additionally, the function and effect of the North Ditch, which runs across the site, is not well
understood. It is possible the direction of groundwater flow could be influenced by these or other
features and could change seasonally.
The results of the groundwater sample analyses show little impacts at the site. Pesticides, PAHs,
and PCBs were not reported above laboratory reporting limits. The only VOC reported above
laboratory reporting limits was methyl-tert-butyl ether (MTBE), a gasoline constituent. However,
its reported concentration is well below screening levels.
Arsenic was found in two of the samples at a concentration above the MCL. As with the
occurrence of arsenic in soils in the Salt Lake Valley, it is relatively common to detect arsenic in
groundwater.
The PFAS analytical data indicate the presence of the compound PFOA in the groundwater at
TOSA-MW02 above the health advisory level of 70 ng/L. As this is a drinking water advisory, and
the water in the shallow aquifer is not consumed, the level is provided solely for reference. Of the
three monitoring wells installed at the site, TOSA-MW02 is closest to the main landfill and may
reflect that PFAS compounds have entered the subsurface from the landfill materials.
6.3 Summary of Soil Gas Conditions
Soil gas samples from within the Pilot Phase area show the presence of chloroform above the
residential screening level in two of the four samples. No other compounds exceed the VISL
within the Pilot Phase area; however, the sample from SG-3, located west of the Pilot Phase area,
reported benzene above its residential VISL in the sample collected in August 2021. In addition,
methane was also elevated in the sample from SG-3.
Soil gas concentrations tend to be highly variable as they are influenced by water level,
precipitation, and barometric pressure, among other factors. As such, variable occurrences of
low concentrations of VOCs in soil gas at the site should be expected. The data suggest a soil
gas intrusion condition would likely exist for buildings constructed on the site.
7.0 CONCLUSIONS
The Limited Site Investigation of the Pilot Phase area of the proposed TOSA Village indicates
minimal impacts from landfilling and other industrial uses of the site and nearby properties. Soil
impacts have not been observed, with the exception of minor amounts of debris in the upper 5
feet in soils in some locations.
Groundwater impacts appear limited to arsenic and PFAS compounds. The source of these
impacts is likely the landfill on the parent parcel which appears to be upgradient of the Site. As

shallow groundwater is not a source of drinking water, the presence of these compounds is not
likely to affect future residents of the proposed village.
Chloroform may pose a potential for vapor intrusion into future buildings on the northern portion
of the Site based on the soil gas analytical results. Additionally, methane appears to be present
at elevated levels farther west of the Site. The presence of VOCs in soil gas at the Site can be
addressed by a vapor intrusion mitigation system.

CASE NARRATIVE
Unless qualified or notated within the narrative below, all sample aliquots were received at the correct
temperature, in the proper containers, with the appropriate preservatives, and within method specified
holding times. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental
samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality
Control are within established criteria except where addressed in this case narrative, a
non-conformance form or properly qualified within the sample results. By my digital signature below, I
affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the
potential to affect the quality of the data have been identified by the laboratory, and no information or
data have been knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
(dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry)Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry)Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J3 The associated batch QC was outside the established quality control range for precision.
J4 The associated batch QC was outside the established quality control range for accuracy.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
P RPD between the primary and confirmatory analysis exceeded 40%.
P1 RPD value not applicable for sample concentrations less than 5 times the reporting limit.
V The sample concentration is too high to evaluate accurate spike recoveries.

CASE NARRATIVE
Unless qualified or notated within the narrative below, all sample aliquots were received at the correct
temperature, in the proper containers, with the appropriate preservatives, and within method specified
holding times. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental
samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality
Control are within established criteria except where addressed in this case narrative, a
non-conformance form or properly qualified within the sample results. By my digital signature below, I
affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the
potential to affect the quality of the data have been identified by the laboratory, and no information or
data have been knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J3 The associated batch QC was outside the established quality control range for precision.
J4 The associated batch QC was outside the established quality control range for accuracy.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.

CASE NARRATIVE
Unless qualified or notated within the narrative below, all sample aliquots were received at the correct
temperature, in the proper containers, with the appropriate preservatives, and within method specified
holding times. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental
samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality
Control are within established criteria except where addressed in this case narrative, a
non-conformance form or properly qualified within the sample results. By my digital signature below, I
affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the
potential to affect the quality of the data have been identified by the laboratory, and no information or
data have been knowingly withheld that would affect the quality of the data.

Dear Ms Williams: "
Enclosed for your review is the iit, Rrorr"ssment (SRA) Report for the Redwood Road
Dump site (referred to as the "Site"). The Site was the primary landfill for Salt Lake City frbm 1923
until 1962. The Site is estimated to contain approximately 1,340,000 cubic yards of refuse and fill;
Interstate 215 was constructed through the center of the Site in 1988 creating an eastern and western
refuse pile;
The nonhern portion of the western landfill is used-for the City's automobile impound lot. Salt
and gravel are stored on the southern portion of the western landfill. A City vehicle washing and
refueling facility is under construction on City property northwest of the easteri landfill. Snow .
cleared from downtown Salt Lake City in the winter is placed on rhe highest portion of the eastern
landfill by City streets personnel, potentially increasing the volume of contaminated landfill leachate.A 1991 Site Investigation and a 2000 Targeted Brownfields Assessment have established the
following:
Elevated concenfations of lead (2,610 mg/kg), benzo (a) pyrene (5,000 pglkg) and dibenz (a, h)
anthracene (1,000 pglkg were identified in subsurface soils. Elevated concentrations of arsenic.
(1,290 pgL) antimony Qa.z p"glL), selenium Q .8 pgtL) and pentachlorophenol (3 ltglL)have
been found in Site groundwater. The sampling of downgradient wells was not included in the
previous studies. Therefore, the extent of downgradient groundwater contamination is unknown.
City Drain Canal surface water lead concentrations rise from a non-detectable backglound
concentration to a high of 59.2 pgtL downstream from the Site. This concentration significantly
exceeds the surface water Criteria Continuous Concentration of 2.5 pglL. Arsenic levels increase
from a background concentration of 61 ltglL to 82.5 p{L after surface water passes the Site. A
wetland environment exists ten miles downstream of the Site at the Great Salt Lake-
Approximately 50 miles of wetland frontage occur within the 15 mile target distance limit.
Several duck hunting clubs are located within these wetland areas. Site.drainage enters the Great
Salt Lake at Farmingron Bay Wildlife Refuge.

We recommend that an Expanded Site Investigation include; (l) the sampling of downgradient
shallow wells and wetiands and, (2) the resampling of groundwater and surface water. Inorganic and
organic sampling data can then be evaluated with previously collected results to better understand
threats to wetlands and wildlife and the potential for site listing on the National.Priorities List.
After reviewing the SRA report, please inform us of any comments or changes that need to be
incorporated in the final version of the document. Please contact Neil Taylor at [phone] if you '

l.O INTRODUCTION
Under authority of the Comprehensive Environmental Response, Compensation, and
Liability Act (CERCLA), as amended by the Superfund Amendments and
Reauthorization Act (SARA), and in accordance with applicable provisions of the
National Contingency Plan, the Utah Department of Environmental Quality, Division of
Environmental Response and Remediation (DERR) has prepared this Site Reassessment
Report (SRA) for the Redwood Road Dump, UTD980961502 (referred to as the "Site")
in Salt Lake City, Salt Lake County, Utah. This SRA was prepared under a cooperative
agreement between DERR and the U.S. Environmental Protection Agency, Region 8
(EPA). The purpose of the Site details described herein is to report information
concerning current Site conditions, assess the threat posed to human health and the
environment from hazardous materials or potential releases of hazardous materials and to
support decisions regarding further investigation under CERCLA or other appropriate
authority. Additionally, contaminant pathways/targets and near future uses of the Site
were examined to identify if any possible changes to the property were imminent. The
Site Visit Report is included as Appendix A. The EPA Preliminary Assessment
Worksheet is provided as Appendix B.
2.0 SITE OBJECTIVES
The objectives of the activities performed during the SRA were related to assessing if
hazardous substances located on-site pose a threat to human health or the environment.
The objectives of this SRA were to:
o Determine the continued presence of contamination in selected media;
o Assess the potential contamination characteristics;
o Assess the potential routes for contaminant migration;
o Assess the suspected exposure pathways;
o Identify potential targets that may be affected by on-site contamination as
well as other targets that may be impacted by the migration of the
contamination via the suspected exposure pathways; and
o Determine if continued assessment under CERCLA is warranted.
3.0 SITE LOCATION DESCRIPTION
3.1 SITE HISTORY AND PREVIOUS WORK
The Site extends west from 1900 West Street to 2200 West Street. and south from 500
South Street to Indiana Avenue (800 South) in Salt Lake City, Utah (Figure l). The Site
is approximately 7A acres in size and is owned by Salt Lake City Corporation (DERR,
1995). The Site is located in the SE y4 of the SE 1/4 of the NE 1/4 of Section 9,
Township I South, Range I West, Salt Lake Base Meridian (USGS, 1962). The Site is
bisected by Interstate 215 (I-2I5) and includes an eastem and western refuse pile. The
Salt Lake City Road Maintenance and Automobile Impound Lot is located directly north
(across 500 South Street) of the western portion of the Site.
The Site was the primary landfill for Salt Lake City fuom 1923 to 1962, when it was
closed to public dumping (DERR, 1995). The Site is estimated to contain approximately
1,340,000 cubic yards of refuse and fill (DERR, 1995). A manifest system was not in
place at the landfill during its operation and no records remain of waste content or
quantities dumped at the Site (UBSHW,1987). In addition, no regulations were in place
to limit possible hazardous waste additions to the landfill. The Site was reported to take
in household, commercial and industrial wastes. The Site has experienced numerous sub-
surface fires, occasional bad odors, caving and differential settling due to decomposing
refuse (UBSFIW, 1987).
The eastern portion of the Site was used from 1962 ta 1995 by Salt Lake City
Corporation's Parks and Recreation Department and Public Services Department for the
disposal of leaves, grass clippings, tree trimmings and storm sewer sludge (DERR, 1995).
I-215 was constructed through the center of the Site in 1988 creating an eastern and
western refuse pile. It is believed that waste characteristics at the Site include municipal
wastes such as household, commercial, industrial and organic materials.
A report entitled "Preliminary Investigations Disposition of Garbage Materials in
Abandoned Landfill" (PI) was prepared for the Utah Department of Transportation
(UDOT), Salt Lake City, Utah, by Dr. David W. Eckhoff in July of 1977 (Eckoff, 1977).
The investigation found that mixed garbage and refuse had been dumped and bumed on
the Site. Twenty auger holes were drilled into the landfill. Forty three measurements for
explosive gas were taken at five foot intervals within the drill holes. The borehole
explosive gas concentrations are provided in Appendix C, Table 1.
The refuse and cover material in the interstate right-of-way was moved to the east pile
during the construction of I-215 in 1988 (DERR, 1995). A Preliminary Assessment (PA)
of the Site was prepared by the Utah Department of Health's Bureau of Solid and
Hazardous Waste in 1987. A 1991 Site Inspection (SI) sampling event included seven
groundwater samples, three surface water samples, ten soil samples and three sediment
samples (DERR, 1992). The monitoring well physical groundwater parameters are
provided in Appendix C, Table 2. The organic data results for groundwater and surface
water samples are provided in Appendix C, Table 3. The inorganic analyses for
groundwater and surface water samples are provided in Appendix C, Table 4. The
organic analyses for soil and sediment samples are provided in Appendix C, Table 5.
The inorganic analyses for soil and sediment samples are provided in Appendix C, Table
6. The original report sample location map is provided as Appendix C, Figure 5. Figure
5a places the approximate sample locations on a 2008 satellite photograph. Figure 5b
provides arsenic concentrations for soil and groundwater samples. The original report
Site groundwater map is provided as Figure 6.
EPA Region 8 gave the Site a higher priority for further investigation under CERCLA on
January 27,1992 (USEPA, 1992). DERR conducted a Site Inspection Prioritization
(SIP) for the Site in September, 1995. The report concluded that the Site may present
hazards to those working and living near it, as well as to transients and bottle collectors
(DERR, 1995). Although the Site is vegetated and surface runoff is slow, the SIP
concluded that the accumulated refuse, soil, and shallow groundwater contain hazardous
substances and these present a threat to human health and the environment.
Chromium and lead contaminated soils were illegally placed on the central part of the
eastern landfill some time during December of 1991 by Tool Design Engineering and
Manufacturing facility personnel (DSIIW, 2010). Chromium concentrations in samples
collected from the soil ranged from 1,240 m/kg to 3,300 mglkg. lrad concentrations
ranged from 1,000 mgkg to 1,800 mgkg. The contaminated soils were discovered in
1992. Approximately 310 cubic yards of soil was removed from the landfill under the
supervision of the Division of Solid and Hazardous Waste and Terracon Consultants in
November L997. All eight cleanup verification samples were non-detect for chromium.
Seven of eight confirmation samples were non-detect for lead with the remaining sample
yielding 0.1 mg/kg lead (Terracon,1997). The EPA residential screening level for lead is
generally 400 mg/kg.
DERR conducted a Targeted Brownsfields Assessment (TBA) for the western portion of
the Site and the Salt Lake City Road Maintenance and Automobile Impound Lot in June,
2000. Selected figures from that assessment together with 2008 satellite photo overlays
are provided as Appendix D. Field work was conducted to assist Salt Lake City
Corporation in gathering additional information about the Site (DERR, 2001). Appendix
D, Figure 1 identifies the approximate location of trenches cut and sample locations.
Phase I consisted of using a backhoe to cut trenches into the subsurface to evaluate the
extent and type of refuse present. Soil samples were collected from selected locations.
Phase II consisted of installing l5 direct push borings across the western landfill. Soil,
soil gas, groundwater and surface water samples were collected and submitted for
laboratory analysis of volatile organics, semivolatile organics, metals and pesticides.
Field observations from the June 15, 2000 trenching and investigation activities suggest
the extent of refuse in the western landfill is potentially limited to the landfill's eastem
bench.
The Portland Cement Superfund site is located directly south of the eastern landfill and
Indiana Avenue on approximately 71 acres. The risks posed by the Portland cement site
were derived from cement kiln dust and chromium bearing bricks which were landfilled
within the Site boundaries. The dust contained several heavy metals including: arsenic,
cadmium, chromium,lead, manganese and molybdenum. The contaminated soil, kiln
dust and chromium bricks were removed from the Portland cement site from 1992
through 1997. The Portland Cement site Record of Decision for Operable Unit Three
(groundwater) states that groundwater contamination is contained in the shallowest
aquifer within the Portland Cement site boundaries by a canal on the eastern boundary of
the Portland Cement site known as the "City Drain", a City sewer line on the east and
north of the site, and a storm water ditch west of I-215. Analytical results of semiannual
groundwater monitoring beneath the Portland Cement site indicate that the contaminant
plume is limited to shallow groundwater within the Portland Cement site boundaries
(DERR,20A7).
3.2 CURRENT SITE CONDITIONS AND NEAR FUTURE USES
The northern portion of the western landfill and the sliver of land directly north of the
western landfill across 500 South Street are used for Salt Lake City's automobile
impound lot. Salt and gravel are stored on the southern portion of the western landfill.
Both landfills are perimeter fenced (DERR, 20I0a). The landfills are closed to the public
with no dumping allowed (Pope, 2010). The eastern landfill is elevated about 10 feet
above the natural ground surface and is covered with soil and natural vegetation. The
landfill is about 300 yards wide and 400 yards long. Various materials are stored on a
flat area northeast of the eastern landfill. Some of these materials include soil from the
City cemetery, wooden posts, large flowerpots for decorative downtown projects, and
large utility poles.
A City vehicle washing and refueling facility is under construction on City property
northwest of the eastern landfill. The City chips trees, limbs and leaves on a large
asphalted area southeast of the eastern landfill. This material is later hauled to the county
landfill for composting. Plans are being considered to extend this asphalted area further
north and convert the area into a temporary model airplane airport. Access to the landfill
outside the asphalted area will remain restricted (Pope, 2010).
Snow cleared from downtown Salt Lake City is placed on the highest portion of the
eastern landfill by City streets personnel. An area on the elevated eastern landfill has
been leveled and covered with clay and gravel for this purpose.
3.3 GEOLOGY, HYDROGEOLOGY. HYDROLOGY AND METEOROLOGY
The Site is located within the Jordan River Valley of the Great Basin Section of the Basin
and Range Physiographic Province. The Jordan River Valley is bounded by the Wasatch
Mountains to the east, the Oquinh Mountains to the west, the Traverse Mountain Range
to the south, and the Great Salt Lake to the north. Basin-fill deposits were eroded from
the Wasatch and Oquirrh Mountains and deposited in the Salt Lake Valley. The general
stratigraphy of the area is charucteized by several hundred to several thousand feet of
unconsolidated and semi-consolidated basin fill deposits. Mountain streams and
historical lakes carried most of the sediment into the basin and ancient Lake Bonneville.
The fine-grained sediments were deposited in deeper portions of Lake Bonneville. The
coarser-grained sediments were deposited along the margins of ancient Lake Bonneville
near the mountains as its level eventually receded to its present level as the Great Salt
Lake (Waddell, et al,1987).
Precipitation that falls as rain or snow in the mountain ranges flows down the range
fronts and recharges the deep aquifer within the Salt Lake Valley. The shallow water
table aquifer is generally recharged by downward infiltration from precipitation, canals,
irrigatedlands and streams as well as by upward leakage from the underlying confined
aquifer (Waddell, et al, 1987). Surficial basin fill deposits within the Salt Lake Valley
generally consist of a series of Quatemary lacustrine, alluvial fan, sand dune, mud-rock
flow, ash falls, glacial and flood plain sediments. Groundwater occurs within these
4
valley fill deposits as a complex series of aquifers (Waddell, et al, 1987). The deeper
aquifer lies in Quaternary deposits of clay, silt, sand, and gravels that are hydraulically
interconnected with individual beds of sand and gravel ranging in thickness from less
than one foot to tens of feet. The maximum thickness of the principal aquifer is greater
than 1,000 feet in the northern portion of the valley. Most deep wells in the Salt Lake
Valley are completed in sediments at depths of less than 1,200 feet.
Municipal wells within four miles of the Site are completed at depths of 1,100 feet and
less (DERR,1992). There are no wells currently in use on-site (DERR, 2010a). Drilling
logs from the four monitoring wells installed at the Site in 1991, in addition to the well
logs from the neighboring Portland Cement site (UTD980718670) reveal a lithology of
clay, silt and sand beneath the landfill (DERR, 1995). A soil survey of the Salt Lake area
identified the soils at the Site as dumps (Du), Salt Air Silty Clay Loam ($a), Loamy
Borrow Pits (Lo), Sandy Terrace Escarpments (Sc), and Decker Fine Sandy Loam (De)
(DERR, t992).
Groundwater flow in the shallow aquifer although complex, due to the interaction with
local surface water and underground utility pathways, is generally to the northwest.
Appendix C, Figure 6 provides known groundwater contours and the anticipated
groundwater flow direction. A 42 inch sanitary sewer is buried at an average depth of 17
feet below grade on the eastern border of the Site. The bedding material of the sewer line
appears to be removing groundwater from the shallow aquifer and routing it to the City
Drain. Groundwater flow under the eastern landfill also appears to be toward the City
Drain (DERR, 1992).
The Salt Lake Valley is located in the Great Basin drainage system, which is a closed
system with no outlets. The Jordan River and its tributaries form the main drainage for
the valley. The Jordan River is a Class 3C stream and discharges into the Great Salt
Lake. The Surplus Canal and the City Drain are located in close proximity to the Site.
The City Drain is located west of I-215 and just east of the western landfill. The surplus
Canal is a losing stream and likely receives no contribution from contaminated
groundwater (EPA, 1998). The "North Ditch" drains the City property northeast of the
eastern landfill. The ditch is piped to a storm drain that flows to the City Drain. The
City Drain is the primary groundwater discharge point. The City Drain joins the Sewer
Canal approximately six miles to the north of the site. The Sewer Canal eventually
discharges into the Great Salt Lake. The Surplus Canal is located approximately 1,000
feet to the west of the Site. The discharge points for the Jordan River, the Surplus Canal
and the Sewer Canal into the Great Salt Lake are characteized by freshwater marshes.
The discharge points are within the confines of the Farmington Bay Waterfowl
Management Area (DERR, 1992).
The Salt Lake Valley is characteized as being semiarid. The normal maximum
temperature ranges from 37.0o F. in January to 93.7" F in July. The normal minimum
temperature ranges from 19.7o F in January to 61.8'F in July. The average annual
rainfall is 15.31 inches per year with a normal monthly high of 2.21inches in April and a
normal monthly low of 0.72 inches in July. The average annual snowfall is 58.0 inches.
The estimated pan evaporation is a 3.91 inches per year. The winds are predominantly
from the south and southeast and have a mean speed of four to five miles per hour
(Ashcroft, 1992).
3.4 SITE CONCEPTUAL MODEL
Water from precipitation and snow dumping flow through the unlined landfill waste. The
leachate contaminates shallow groundwater. The contaminated groundwater flows to the
City Drain Canal which bisects the site and is carried north by surface water flow into
wetlands and bird habitats. Contaminated groundwater also flows to the northwest in the
subsurface, potentially contaminating shallow, private water wells. The site conceptual
model is illustrated as a flow chart in Fisure 3.
4.0 PATHWAY ANALYSIS
4.1 SITE WASTE SOURCES QUANTITY AND CHARACTERISTICS
Both west and east landfills contain municipal trash and unknown quantities of hazardous
materials. Both petroleum and chemical wastes were found in soil borings that were part
of a 1977 IJDOT landfill waste investigation. The volume of the landfills is calculated at
approximately 1,338,000 cubic yards (Eckoff,1977). The landfills are not properly
contained to minimize leaching of materials into the shallow groundwater.
4.2 GROUNDWATER MIGRATION PATHWAY
4.2.1 TARGETS
Seventeen municipal wells from three cities are located within the four mile target
distance range. All wells are located east or south of the Site and hydraulically
upgradient (DDW, 20I0a; DDW,2010b). All three city water systems are blended with
multiple groundwater and surface water sources. Table 1 identifies the population served
by the three public water systems having wells located within four miles of the Site.
Table L
Population Receiving Groundwater from Wells Located
within Four Miles of the Site
Svstem Name Population Served
Granger-Hunter Improvement District 106.000
Salt Lake City 387,506
South Salt Lake 18,000
Total Population Served 5l l,506
Approximately 4,102 underground points of diversion are located within four miles of the
Site. The uses for the large majority are for "domestic" or irrigation purposes and most
are upgradient of the Site (DWR, 2010). The closest downgradient well is approximately
400 yards northwest of the Site, north of 500 South and east of the Surplus Canal. The
6
well is 2 inches in diameter, 280 feet deep and was drilled in 1947. All downgradient
wells within 1.5 miles are from 200 to 400 feet deep, artesian wells, drawing from the
deeper, confined aquifer. It is likely that shallow groundwater flows into the City Drain
Canal that bisects the site.
4.2.2 SUMMARY OF PAST RESULTS
4.2.2.1DERR 1991 Site Inspection
Four monitoring wells installed by EPA and two Portland Cement CERCLA Site
monitoring wells to the south of the Site were sampled (Appendix C, Figure 5). A
duplicate sample was also collected from RD-MW-O2.
Appendix C, Tables 3 and 4 summarize the analytical results for the seven groundwater
samples. All samples were analyzed for volatiles, base-neutrallacid extractables,
pesticides, PCBs and metals. There were no pesticide or volatile compounds detected in
the groundwater samples. There were no organic chemical concentrations found above
Superfund Chemical Data Matrix (SCDM) benchmarks (SCDM, 2004). Appendix C,
Table 4 lists the inorganic analyses. A summary of the metals detected near or above
SCDM benchmarks is provided in the table below. Arsenic was detected at314 pglL,
248 p"glL and 179 pgLir three of the four downgradient wells compared ta 19 p.glLin
the background well. Sample RD-MW-OS contained 3a.2 TtglL antimony. Selenium was
detected in RD-MW-O1 at A.8 1.tglL.
4.2.2.2 DERR 2000 Targeted Brownfields Assessment
Approximately 15 direct push borings were installed across the Site during the 2000
TBA. Soil, soil gas, groundwater and surface water samples were collected and
submitted for volatile organic, semivolatile organic, pesticides, PCBs and dissolved
metals analysis.

Sampling results from the June 2000 TBA revealed pentachlorophenol in sample RRD-
11 at an estimated concentration of 3 ttdL. The MCL for this compound is I pgll-. No
other organics were detected in the groundwater above SCDM benchmarks (DERR,
2001).
Arsenic was detected in many groundwater samples above the MCL of I0 ltgll-. Arsenic
was found in sample RRD-I at 1,290 ptglL and in RRD- 2 at 1,000 pgL. Both sample
locations are north of the Site (Appendix D, Figure 5). Dissolved arsenic was reported in
RRD-7 at an estimated concentration of 1,170 pgL. Other groundwater samples ranged
from 2-4 trt"gll- to 236 1t glL. No other dissolved metals were detected in the groundwater
above SCDM benchmarks. The sampling locations and groundwater arsenic
concentrations from the June 2000 sampling event are included as Appendix D, Figure 5.
4.2.3 DATA GAPS
No shallow groundwater samples have been collected farther downgradient (northwest)
of the Site than the City impound lot north of 500 South. The closest downgradient well,
located approximately 400 yards northwest of the Site, has not been sampled. No
groundwater sampling has been conducted since June 2000. The present extent of
downgradient arsenic groundwater contamination is therefore unknown.
4.3 SOIL EXPOSURE PATHWAY
4.3.1 TARGETS
The Redwood Road Dump is enclosed by chain link and barbed wire fences. This barrier
prevents unauthorized vehicle access (DERR, 2010a). There is no on-site population or
residences. There are no schools or day cares located within 200 feet of the site.
4.3.2 SUMMARY OF PAST RESULTS
4.3.2.1 UDOT 197 7 Preliminary Inspection
One rotary hole and 19 auger holes were drilled into the landfill from April toMay L977.
Forty three refuse (soil) samples were analyzedfor total solids, volatile solids, BOD, and
moisture content. Explosive gas concentrations were measured for a few holes in April
L977 and measured twice in May 1977 for all holes at various depths. Borehole
explosive gas concentrations ranged from zero to 27 percent by volume (Eckoff, 1977).
Explosive gas concentrations are provided as Appendix C, Table 1.
Several locations repeatedly yielded methane concentrations above the lower explosive
limit (LEL). Two of the sampling locations showed methane concentrations above 10
percent by volume. In 12 of the 20 borings, petroleum products were found at or near the
water table. One of the drill holes, G-3C, cited the presence of a "chemical waste" at a
depth of 8-10 feet. Thickness of the refuse in the landfill was determined to vary
between one foot and29 feet, with the refuse-natural ground interface undulating
between elevations of 4216-4224 feet above sea level.
4.3.2.2 DERR 1991 Site Inspection
Ten soil samples were collected numbenng RD-SO-0I through RD-SO-l0. Sample
locations are shown in Appendix C, Figure 5 and 5a. Eight of the ten were surface
samples. Sample RD-SO-02 is the background sample. Samples RD-SO-06 and RD-SO-
07 can be considered source samples of "oily waste" taken near the water table from
monitoring wells MW- 2 and MW-4. It does not appear that these two samples were
submitted for inorganic analysis. Sample results can be found in Appendix C, Tables 5-
6.
Appendix C, Tables 5 and 6 summarize the analyical data results for soil and sediment
samples. Site soils contain above background concentrations of 21 BNA compounds,
five VOA compounds, 12 pesticide compounds, and one PCB compound. None are
above SCDM benchmarks. The PCB compound, aroclor-1260, was detected in RD-SO-
09 at 150 ppb. Table 6 indicates a release of at least 10 metals to the soil has occurred at
the Site. Concentrations of barium, calcium, chromium, copper, iron, lead, mercury,
nickel, sodium, and zinc were detected over three times that of the background sample.
None were above SCDM benchmarks. However, lead has no established SCDM
benchmark. Lead was detected in sample SO-10 at2,610 mdkg in the northern corner of
the western landfill. This sample was taken directly above the refuse inside a hole
previously used to excavate old bottles about three feet below ground surface.
4.3.2.3 DERR 2000 Targeted Brownfields Assessment
Soil samples were collected during installation of the direct push groundwater samples
and from selected trench locations across the Site. Soil samples were collected directly at
the soil/water interface. Most soil samples were collected between seven to nine feet
below ground surface. Soil sample locations are provided as Appendix D, Figure 1 and
provide 2008 satellite imagery for the sample locations.
Lead was reported in sample T-3 at 1,760 mglkg. Lead was reported in sample SB-2 at an
estimated concentration of 1,930 m/kg. Poly nuclear aromatic hydrocarbon compounds
were detected from the base of a trench cut (SB-2) along the central portion of the east
bench. Soil samples collected from the base of the 10 foot trench cut revealed benzo (a)
pyrene at 5,000 ug/kg and dibenz (a,h) anthracene at 1,000 udkg. The SCDM CRSC for
both compounds is 880 udkg. Selected figures from the study are provided in Appendix
D. Figure 4 is the original report sample map identifying the benzo (a) pyrene
concentrations found in soil samples from the western landfill. Figure 4a is the historic
report sample map detailing the lead concentrations at the western landfill.
No VOCs, SVOCs or PCBs/Pesticides were detected in any other samples above SCDM
benchmarks or the EPA Region 3 commercial/industrial soil screening criteria. Arsenic
was reported in all soil samples collected from the western landfill. The highest reported
concentration was 43.9 mg/kgwith the remaining concentrations ranging from 6.0 mdkg
to 25 mgkg.
4.3.3 DATA GAPS
Only limited subsurface soil hazardous constituent analysis has been conducted for the
eastern landfill.
4.4 SI.IRFACE WATER PATHWAY
4.4.1 TARGETS
There are no surface drinking water sources within the 15 mile target distance limit.
Surface waters are not used for fishing within 15 downstream miles. A wetland
environment exists at the Great Salt Lake which is approximately l0 miles downstream
of the Site (Appendix B, Figures on pages 10 and 11). Approximately 50 miles of
wetland frontage occur within the 15 mile target distance limit (USDI, 1990). Several
duck hunting clubs are located within these wetland areas (DWLR, 2010). The Site is
located in a 100 year flood zone (FEMA, 2010).
4.4.2 SUMMARY OF PAST RESULTS
4.4.2.1DERR 1991 Site Inspection
Three surface water samples were collected at the Site, as well as three sediment samples
(see Appendix C, Figure 5 and 5a). A quality control trip blank water sample was also
taken. Upgradient and downgradient water samples were collected from the City Drain
and a water sample was taken from the unnamed north ditch. The up-gradient City Drain
sample served as the background sample. Sediment samples were taken in the same
general location as the surface water samples.
Surface water sample results tables from this investigation are provided in Appendix C
(Tables 3-6). The SCDM surface water environmental pathway benchmark for acute
exposure is the Criteria Maximum Concentration (CMC) and the benchmark for chronic
exposure is the Criterion Chronic Concentration (CCC). The environmental toxicity of
metals in surface water depends upon water hardness. As the water hardness of the City
Drain has not been determined, the default CMC and CCC values for a water hardness of
100 mg/L is provided. Lead was detected in the north ditch sample at23.6 ltglI-. The
CMC for lead is 65 ltgtL and the CCC for lead is 2.5 pglL. Antimony was detected at25
1tg[LfromRD-SW-02. No CMC or CCC for antimony has been established. Arsenic
was also detected in the upgradient City Drain sample at 53.4 ltgll- and in the
downgradient sample at 59.2 p.g& (CMC = 340 tLgL, CCC = 150 pglL).
Appendix C, Table 5 identifies the 11 BNA, six pesticide and two VOA compounds that
were detected in the sediment samples. The majority of these contaminants were
detected in the north ditch, indicating they most probably originated from the landfill.
10
The north ditch sediment sample contained three metal concentrations that were more
than three times the concentration in the upgradient City Drain sediment sample. These
metals include lead (68.2 mdkg), magnesium (33,000 mdkg) and zinc (222 mglkg).
4.4.2.2 DERR 2000 Targeted Brownfields Assessment
Surface water samples RRD-SW-I, RRD-SW-Z andRRD-SW-3 were collected from the
City Drain which borders the western landfill on the east. RRD-SW-4 was collected
from the northern portion of a possible wetland area identified on the central portion of
the eastern landfill. RRD-SW-5 was a duplicate of RRD-SW-4.
Appendix D, Tables 3,6,9 and llsummarize the surface water analytical results.
Arsenic was reported in the southernmost (background) surface water sample (RRD-SW-
1) at 61 pglL, in RRD-SW-Z at79.7 lrdL and in RRD-SW-3 at82.8 pglL. All measured
surface water arsenic concentrations were below the CMC QaU pdL\ and the CCC (150
pglL). Lead increased from the background non-detect concentration to 56.1 1tglL at
RRD-SW-2 and 50.3 ltglL at RRD-SW-3 (CMC = 65 p"dL, CCC = 2.5 pelL). No other
metals were reported above SCDM benchmarks.
4.4.3DATA GAPS
Determining the appropriate metal toxicity benchmark requires knowing the average
hardness of City Drain surface water. This value has not yet been determined.
4.5 AIR MIGRATION PATHWAY
4.5.1 TARGETS
There is no on-site population or residences at the Redwood Road Dump. There are no
schools or day cares located within 200 feet of the site. There is a population of 130,095
within the four-mile Target Distance Limit (DERR,2010b). Table 3lists the target
population within various distances. Both western and eastern landfills are fenced. Two
means of access are available to the eastern landfill; one is from the north through a gate
which is locked at night, and one from the south through a road barrier. Approximately
50 miles of wetland frontage occur within the 15 mile target distance limit (USDI, 1990).

4.5.2 SUMMARY OF PAST RESULTS
4.5.2.1 UDOT 197 7 Preliminary Inspection
One rotary hole and 19 auger holes were drilled into the landfill from April toMay 1977.
Explosive gas concentrations were measured for a few holes in April 1977 and measured
twice in May 1977 for all holes at various depths. Several locations repeatedly yielded
methane concentrations above the lower explosive limit (LEL).
4.5.2.2 DERR 2000 Targeted Brownfields Assessment
Soil gas samples were collected from two locations along the eastern bench of the
western landfill in accordance with the protocol established in the TBA Workplan and
analyzed for methane. Methane was reported in SG-l at23,000 ppmv (46 percent of the
lower explosive limi|. Methane was not reported in SG-2 above the level of detection.
4.5.3 DATA GAPS
None identified.
5.0 SIJMMARY AND CONCLUSIONS
The Site was the primary landfill for Salt Lake City from 1923 untll1962 and is
estimated to contain approximately 1,340,000 cubic yards of refuse and fill. The Site was
reported to take in household, commercial and industrial wastes. I-215 was constructed
through the center of the Site in 1988 creating an eastern and western refuse pile. The
refuse and cover material in the interstate right-of-way was moved to the east pile during
the construction. Thickness of the refuse in the landfill varies between one foot and29
feet, with the refuse-natural ground interface undulating between elevations of 4216-4224
feet.
Chromium and lead contaminated soils were illegally placed on the central part of the
eastern landfill some time during December of 1991. The contaminated soils were
removed from the landfill in November 7997.
The northern portion of the western landfill is used for Salt Lake City's automobile
impound lot. Salt and gravel are stored on the southern portion of the western landfill.
The eastern landfill is elevated about 10 feet above the natural ground surface and is
covered with soil and natural vegetation. The eastern landfill is about 300 yards wide and
400 yards long. Various materials are being stored on a flat area northeast of the eastern
landfill.
A City vehicle washing and refueling facility is under construction on City property
northwest of the eastern landfill. Plans are being considered to extend this asphalted area
further north and convert the area into a temporary model airplane airport. Snow cleared
T2
from downtown Salt Lake City in the winter is placed on the highest portion of the
eastern landfill by City streets personnel.
The Portland Cement Superfund site is located directly south of the eastern landfill and
south of Indiana Avenue. Semiannual monitoring of the contaminated groundwater
beneath the Portland Cement site indicates that the shallow aquifer contaminant plume
continues to be contained within the Portland Cement site boundaries.
The 1991 SI and 2000 Tareeted Brownfields Assessment have established the followins:
o Soil - Concentrations of barium, calcium, chromium, copper, iron, mercury,
nickel, sodium, and.zinc were detected in surface soils over 3 times that of the
background sample. In particular, lead was detected in the subsurface soils as
high as 2,610 mdkg.
Concentrations of benzo (a) pyrene (5,000 pglkg and dibenz (a, h) anthracene
(1,000 pglkg were identified in subsurface soils above SCDM benchmarks. The
SCDM CRSC for both compounds is 880 pglkg. There is no on-site population
or residences at the Redwood Road Dump. There are no schools or day cares
located within 200 feet of the site.
o Groundwater - The presence of arsenic (I,290 pgL) antimony (34.2 1t"glL),
selenium GaS pg\-), pentachlorophenol (3 pglL) have been found in Site
groundwater above SCDM benchmarks. Arsenic contamination above the l0
1.tgll- groundwater MCL is widespread. However, the closest downgradient
well, located approximately 400 yards northwest of the Site, has not been
sampled. The extent of downgradient groundwater contamination to the
northwest is, therefore, unknown. Seventeen municipal wells from three cities are
located within the four mile target distance limit. All are located east or south of
the Site and hydraulically upgradient. All downgradient wells are privately
owned.
o Surface water - The City Drain Canal bisects the site. Water from the canal
eventually enters the Great Salt Lake at Farmington Bay Wildlife Refuge
approximately 10 miles downstream of the site. Approximately 50 miles of
wetland frontage occur within the 15 mile target distance limit (USDI, 1990).
Several duck hunting clubs are located within these wetland areas. There are no
surface drinking water sources within the 15 mile target distance limit of the Site.
Surface waters are not used for fishing within 15 downstream miles.
City Drain Canal surface water lead concentrations rise from a non-detectable
background concentration to a high of 59.2 ltglL downstream of the Site. This
concentration significantly exceeds the surface water CCC of 2.5 pglL. However,
although elevated levels of lead have been detected in subsurface site soils,
elevated levels of lead have not been detected in Site sroundwater. Arsenic levels
t3
increase from a background concentration of 6l L+glL to 82.8 pgll downstream of
the Site.

SITE VISIT REPORT
SITE VISIT REPORT
For the Redwood Road Dump
CERCLIS ID UTD98O9615O2
On March 9 and 22,2010 Neil Taylor with the Utah Department of Environmental
Quality, Division of Environmental Response and Remediation conducted a site visit of
properties associated with the investigation of the Redwood Road Dump (Site). This
report describes the Site visits. Supporting photographs can be found at the end of the
visit description. on March 22, Neil Taylor was accompanied by val Pope, Parks
Division Manager with the Salt Lake city Department of Public Services.
The Site is located between 500 South on the North and Indiana Avenue on the South and
from 1900 West on the East to 2200 West on the West. The Redwood Road Dump
consists of westem and eastern covered landfills. Historically the landfills were one unit
but are now bisectedby l-215. Both landfills are covered with soil and vegetated with
native grasses.
We first entered the eastem landfill using an access road located directly behind the Parks
Division building which is located at 1963 West 500 South. Various materials are being
stored on the flat area northeast of the elevated and covered eastern landfill. Some of
these materials include soil from the city cemetery, wooden posts, large flowerpots for
decorative use downtown, and large utility poles.
A city vehicle washing and refueling facility is under construction just northwest of the
eastem landfill. Trees limbs and leaves are chipped up on a large asphalted area
southeast of the eastem landfill. This material is later hauled to the county landfill for
composting. Snow cleared from downtown in the winter is dumped on the highest
portion of the eastern landfill. An area on the elevated eastem landfill has been leveled
and covered with clay and gravel for this purpose.
An open ditch runs north northeast from the Southeastern property drainage to behind the
Parks Division building. The drainage is then piped from the Southwest quarter of the
Parks building to a storm drain on 500 South. The "North Drain" described in previous
site investigation reports, no longer appears to exist.
The narrow, elevated, western portion of the landfill is located just west of I-215 and the
City Drain canal and east of a variety of city and private properties running down Delong
Street (2105 West). A row of commercial businesses are located on the northern portion
of Delong Street. The city impound lot is located east of these properties. The northem
half of the western landfill is located east of the city impound lot.
The Salt Lake City Streets Division owns the southern half of Delong Street. This
includes the southern half of the western landfill. The elevated southem half of the
landfill is being used for storage of a variety of gravel used in street repair and tree limbs.

BACKGROT IID/OPERATTNG HI STORY
6. DESCRIBE OPERATING HISTORY OF SITE: the Site was the primary landfill for Salt Lake
City from l-923 until l-952. The Site is estimated t.o contain approximatefy 1,3.40,000
cubic yards of refuse and fill. The Site was reported to take in household,
commercial and industrial wastes. I-215 was constructed through the center of the
Site in 1988 creat,ing an eastern and western refuse pi1e. The refuse and cover
material in the Interstate right-of-way was moved to the east pile during the
construction. Thickness of the refuse in the landfill varies between one foot and 29
feet, with the refuse-natural ground int,erface undulating between elevations of 4216-
4224 feeE.

12.BRIEFLY EXPLAIN HOW WASTE QUANTITY WAS ESTIMATED (e.9., historical records or
manifests, permit applications, air photo measurements, etc.): A report entitled
"Preliminary Investigations Disposition of Garbage Materials in Abandoned Landfill"
(PI) was prepared for the Utah Department of Transportation (UDOT), Salt Lake Citv,
Utah, by Dr. David W. Eckhoff in Ju]y of l-977. rhe investigation found that mixed
garbage and refuse had been dumped and burned on the site. Twenty auger holes were
drilled into t,he landfill from which the volume and type of waste was cal-culated.

four downgradient we1ls compared to 19 pg/L in a background well. Antimony was
detected at'34.2 pg/L in one well and above background concentrations. In 2000,
arsenic was detected in manv groundwater samp]es above the MCL of 10 pr.g/L. Arsenic
was found at l-,290 pg/L and at L,000 pg/L in two sample wells locaEed north of the
Site. Dissolved arsenic was reported in on the western edge of the western fandfill
aE an estimated concentration of l-,1-70 pg/L. other groundwater samples ranged from
2.4 uq/L Lo 236 uq/L

18. DISCUSS THE PROBABLE SURFACE RLINOFF PATTERNS FROM THE SITE TO SURFACE WATERS: The
Surplus Canal and the City Drain are located in close proximitv to the site. The
"North Ditch" drains the City property northeast of the east,ern l-andfill. The ditch
is piped to a storm drain that flows to the City Drain. The City Drain is located
west of I-215 and just, east of the western landfill. The City Drain is the primary
groundwater discharge point. The Citw Drain joins th€ Sewer Canal approximately six
miles to the north. The Sewer Canal eventually discharges into Ehe Great Salt Lake
approximatelv l-0 miles downstream of the Site. The Surplus Canal is located
approximately 1,000 feet to the west of the Site. The discharge points for the
Jordan River, the Surplus Canal and the Sewer Canal into the Great SaIt Lake are
characterized by freshwater marshes. The discharge points are withj-n the confines of
the Farmington Bay Waterfowl Management Area

REMEDIAL SITE ASSESSMENT DECISION – EPA Region 08
Site Name:REDWOOD ROAD DUMP
Alias(es):
City:MAGNA County or Parish:SALT LAKE State:UT
Refer to Report Dated:10/24/2018 EPA ID:UTD980961502
Report Developed By:STATE State ID:
Report Type:Expanded Site Inspection #001 Decision Date:10/24/2018
1. Further Remedial Site Assessment Under CERCLA (Superfund) is not required because:
NFRAP-Site does not qualify for the NPL based on existing information
2. Further Assessment Needed Under CERCLA.
3. Remedial study/cleanup needed.
Decision/Rationale:
Historic city landfill located about two miles south-southeast of the Salt Lake City International Airport. The landfill
received solid waste from 1923 to 1962 before being closed to public dumping. Municipal wastes such as household,
commercial, industrial and organic materials are believed to be buried on-site. Chromium and lead contaminated soils
were illegally dumped at the site in 1991 and subsequently removed under the direction of the Utah Division of Solid
and Hazardous Waste in 1997. The landfill is currently covered with top soil to various depths. Previous investigations
have identified elevated levels of organic compounds, heavy metals and the pesticides in on-site soils.
The Utah Department of Environmental Quality (UDEQ) completed an Expanded Site Inspection (ESI) in 2017 to
evaluate potential health threats related to the site. According to the ESI report, exposure to contaminated soils is
limited by perimeter fencing and current operations and maintenance. There are no on-site residents, schools or
daycares located with 200 feet of the site. Arsenic, antimony, selenium and pentachlorophenol were found in shallow
groundwater, but there are no downgradient wells used for drinking water within four miles of the site. Elevated
concentrations of heavy metals in nearby surface water and sediment could not be attributed to the site due to potential
upstream sources of contamination.
Based on the review of the ESI report, the U.S. Environmental Protection Agency (EPA) concurs with UDEQ’s
recommendation of No Further Remedial Action Planned (NFRAP), at this time. The basis for the NFRAP determination
is provided above. A NFRAP designation means that no additional remedial steps under the Federal Superfund
program will be taken at the site unless new information warranting further Superfund consideration or conditions not
previously known to EPA regarding the site are disclosed. In accordance with EPA's decision regarding the tracking of
NFRAP sites, the referenced site may be removed from EPA’s Active site inventory and placed in a separate Archive
site inventory as an historical record if no further Superfund interest is warranted. Archived sites may be returned to the
Active site inventory if new information necessitating further Superfund consideration is discovered.

Dear Mr. Dunham:
Enclosed for your review is the Expanded Site Investigation (ESI) Analytical Results
Report (ARR) for the Redwood Road Dump (Site) (CERCLIS ID# UTD980961502) located in
Salt Lake City, Utah.
The ARR focuses on the surface water exposure pathway and provides inorganic metal
concentrations from surface water, and sediment samples collected upgradient and downgradient
of the Site from the City Drain Canal. Other exposure pathways have been extensively examined
by prior investigations and are summarized in the report. ARR appendices include key data tables
and figures from these previous studies.
Above-background concentrations of barium, calcium, chromium, copper, iron, lead,
mercury, nickel, sodium, zinc, benzo(a)pyrene, dibenz(a, h)anthracene, and arochlor 1260 were
detected in surface soils. However, there is no on-site population or residences at the Site. There
are no schools or day cares located within 200 feet of the Site. No exposure to contaminants is
anticipated at the Site when the Site is appropriately maintained and controlled under current
operating practices. Arsenic, antimony, selenium, and pentachlorophenol were found in Site
groundwater above SCDM benchmarks. However, there are no downgradient wells used for
drinking water within four miles from the Site.
Although a 2000 Targeted Brownfield Assessment attributed a release of lead and arsenic
from the Site to the City Drain Canal, data from this most current sampling show a higher
background concentration of both metals than in most downgradient surface water samples. The
City Drain Canal joins the Northwest Oil Drain and flows to the Great Salt Lake. The Northwest
Oil Drain has an extensive history of petroleum and industrial contamination. Elevated
concentrations of lead have been documented in sediments at the mouth of the Northwest Oil

Drain. However, it does not appear that the Site is a contributor to the lead contaminant load as
upgradient lead contamination in the City Drain Canal is higher in the background sample than in
any downgradient sample. Thus, we recommend a finding of No Further Remedial Action for the
Site.
After reviewing the ESI ARR, please inform us of any comments or changes that need to
be incorporated into the final version of the document. If you have any questions, please contact

1.0 INTRODUCTION
Under authority of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as
amended by the Superfund Amendments and Reauthorization Act (SARA), and in accordance with applicable
provisions of the National Contingency Plan, the Utah Department of Environmental Quality, Division of
Environmental Response and Remediation (DERR) has prepared this Expanded Site Investigation (ESI)
Analytical Results Report (ARR) for the Redwood Road Dump, UTD980961502, (referred to as the “Site”) in Salt
Lake City, Salt Lake County, Utah. This ESI was prepared under a cooperative agreement between DERR and
the U.S. Environmental Protection Agency, Region 8 (EPA). Surface water and sediment samples were collected
as part of this ESI. Field notes and photographs were produced throughout the sampling event to document
sample locations, sampling methods and field observations. The field notes and photographs were later
transcribed to the Field Activities Report (Appendix A).
2.0 SITE OBJECTIVES
The objectives of this ESI were to:
• Determine the presence of contamination in selected media.
• Assess the potential contamination characteristics.
• Assess the potential routes for contaminant migration.
• Assess the suspected exposure pathways.
• Address data gaps from previous assessments.
• Identify potential targets that may be affected by on-site or off-site contamination as well as other
targets that may be impacted by the contamination migration via the suspected exposure
pathways.
• Determine if additional assessment under CERCLA is warranted.
3.0 SITE DESCRIPTION
3.1 Site Location and Description
The Site includes two historical landfills, bisected by Interstate 215 (1-215). The eastern landfill extends west from
1900 West Street to 1-215 at about 2000 West. The northern border is 500 South Street. The western half of the
landfill begins at 1-215 at about 2000 West and continues to 2200 West. The southern border is Indiana Avenue
and the northern border is 500 South (Figure 2). The Site is approximately 70 acres in size and is owned by Salt
Lake City Corporation. The Site is located in the Southeast % of the Southeast 1/4 of the Northeast 1/4 of Section 9,
Township 1 South, Range 1 West, Salt Lake Base Meridian (U.S. Geological Survey, 1975). The Salt Lake City
Road Maintenance and Automobile Impound Lot is located directly north (across 500 South Street) of the eastern
landfill (Yeomans, 1995). In 2014, Salt Lake City constructed a four-acre, one-megawatt solar farm on the
northern flank of the eastern landfill. The solar panels are held down by surface-placed concrete ballast blocks.
These concrete blocks sit on a layer of rock that was placed over the existing grade to not disturb the cap (Sokol,
2015). The city operates a large wood chipping and composting operation on the south end of the western landfill
(Figure 2). The City Drain canal flows south to north on the eastern edge of the western landfill. The City Drain
flows approximately 11 miles to the Northwest Oil Drain (NWOD) Delta (the Delta) of the Great Salt Lake. The
Delta sediments are contaminated with oil, grease, lead, and mercury (TechLaw, 2012). The NWOD also flows to
the Delta (Figure 1).

3.2 Site History and Previous Work
3.2.1 Site History
The Site was the primary landfill for Salt Lake City from 1923 until 1962, when it was closed to public dumping.
The Site is estimated to contain approximately 1,340,000 cubic yards of refuse and fill (Eckoff, 1997). A manifest
system was not in place at the landfill during its operation, and no records remain of waste content or quantities
dumped at the Site (Utah Bureau of Solid and Hazardous Waste, 1987). The eastern portion of the Site was used
from 1962 to 1995 by Salt Lake City Corporation’s Parks and Recreation Department and Public Services
Department for the disposal of leaves, grass clippings, tree trimmings and storm sewer sludge. 1-215 was
constructed through the center of the Site in 1988 creating an eastern and western refuse pile. It is believed that
waste characteristics at the Site include municipal wastes such as household, commercial, industrial and organic
materials (Yeomans, 1995).
The northern portion of the east landfill, and the sliver of land directly north of the eastern landfill across 500
South Street, are used for Salt Lake City's automobile impound lot. Salt and gravel are stored in the southern
portion of the western landfill. Both landfills are perimeter fenced (Taylor, 2010). The landfills are closed to the
public with no dumping allowed. A City vehicle washing and refueling facility has been constructed on City
property northwest of the eastern landfill.
Chromium and lead-contaminated soils were illegally placed in the central part of the eastern landfill sometime
during December of 1991 by Tool Design Engineering and Manufacturing facility personnel (Utah Division of Solid
and Hazardous Waste, 2010). Chromium concentrations in samples collected from the soil ranged from 1,240
milligrams per kilogram (mg/kg) to 3,300 mg/kg. Lead concentrations ranged from 1,000 mg/kg to 1,800 mg/kg.
The contaminated soils were discovered in 1992. Approximately 310 cubic yards of soil was removed from the
landfill under the supervision of the Utah Division of Solid and Hazardous Waste and Terracon Consultants in
November 1997. Historical records do not clearly identify the location of the contaminated soil. All eight cleanup
verification samples were non-detect for chromium and lead.
3.2.2 Preliminary Investigation
A report entitled "Preliminary Investigations Disposition of Garbage Materials in Abandoned Landfill" (PI) was
prepared for the Utah Department of Transportation (UDOT), Salt Lake City, Utah, by Dr. David W. Eckhoff in July
of 1977. Twenty auger holes were drilled into the landfill. The investigation found that mixed garbage and refuse
had been dumped and burned on the Site. The garbage is covered to various depths by soil, but not with an
engineered landfill cap (Eckoff, 1997). A Preliminary Assessment (PA) of the Site was prepared by the Utah
Department of Health's Bureau of Solid and Hazardous Waste in 1987.
3.2.3 Site Inspection
A 1991 Site Inspection (SI) sampling event included seven groundwater samples, three surface water samples,
ten soil samples and three sediment samples (Hawkins, 1992). All samples were analyzed for volatiles, base-
neutral/acid extractables, pesticides, PCBs, and metals. Selected data and figures from the 1991 SI are provided
as Appendix B. A sample location map is provided as Appendix B, Figure 1.
Soil sample analyses indicated the presence of 21 base neutral/acid compounds, five volatile organic compounds,
12 pesticide compounds, and arochlor 1260 (a polychlorinated biphenyl (PCB) compound). Concentrations of the
polycyclic aromatic hydrocarbons (PAHs) benzo(a)anthracene and benzo(a)pyrene exceeded the Superfund
Chemical Data Matrix (SCDM) Cancer Risk Screening Concentration (CRSC) benchmarks in several on-site
locations. These PAHs likely formed during the incomplete combustion of garbage and wood. The PCB Aroclor-
1260 was also detected at 150 mg/kg in one soil sample collected from the center of the eastern landfill. This
exceeds the 0.3 mg/kg CRSC soil benchmark. No other soil contaminant exceeded SCDM benchmarks (U.S
Environmental Protection Agency, 2017). Figure 4 provides the location and concentration of benzo(a)pyrene
detected in both landfills in either the Site Investigation or a Targeted Brownfield Assessment (TBA) conducted in
UTAH DIVISION OI KNVIRONMKNTAI. KKSPONSK AND REMEDIATION
REDWOOD ROAD DUMP IITD980961502
The upgradient City Drain surface water sample contained aluminum at a concentration of 104 microgram per liter
(pg/L). However, the downgradient, surface water sample from the City Drain contained aluminum at a
concentration of 728 microgram per liter (pg/L). All surface water samples exceeded the 87 pg/L Criteria Chronic
Concentration CCC, SCDM environmental benchmark for aluminum. The downgradient surface water sample
also contained lead at a concentration of 8 pg/L. This result exceeds the 2.5 pg/L CCC benchmark.
Arsenic was detected at 314, 248 and 179 pg/L in three of four downgradient wells as compared to 19 pg/L in the
background well. The Maximum Contaminant Level (MCL) for arsenic is 10 pg/L. The closest downgradient
groundwater sample also contained 34.2 pg/L antimony, which is also above the 6 pg/L MCL. The location of
elevated concentrations of arsenic in groundwater detected during the SI or TBA investigations are provided in
Figure 5. The nearest downgradient well used for drinking water is located 4.9 miles north of the Site.
Lead was detected in Site soils at concentrations ranging from 15.5 to 2,610 mg/kg. The highest concentration
was found in the northern corner of the western landfill. There is no SCDM benchmark for lead in soil. The
Regional Screening Level for lead is 400 mg/kg. The highest concentration of iron in the City Drain (1,060 pg/kg)
and in groundwater under the eastern landfill (2,570 pg/kg) exceeded the 1,000 pg/kg CCC.
The Site received a higher priority for further investigation under CERCLA on January 27, 1992. DERR
conducted a Site Inspection Prioritization (SIP) for the Site in September 1995 (U.S. Environmental Protection
Agency, 2013). The report concluded that the Site may present hazards to those working and living near it, as
well as to transients and bottle collectors (Yeomans, 1995). Although the Site is vegetated and surface runoff is
slow, the SIP concluded that the accumulated refuse, soil, and shallow groundwater contain hazardous
substances and these present a threat to human health and the environment.
3.2.4 Targeted Brownfield Assessment
In 2000, the Salt Lake City Corporation considered relocating the City’s existing fleet maintenance and office
facilities to the Site. The City requested DERR assistance in screening the site for potential contamination. The
objective of the June 2000 targeted Brownfields Assessment (TBA) was to collect screening information from
selected locations across the site to evaluate environmental conditions in preparation for a potential change in
land use. The DERR conducted a TBA for the western portion of the Site and the Salt Lake City Road
Maintenance and Automobile Impound Lot in June 2000. Selected data and figures from the TBA are provided as
Appendix C. Appendix C, Figure 3 identifies the approximate location of trenches cut and sample locations. Soil
samples were collected from preselected locations, and 15 direct push borings were installed across the western
landfill. Soil, soil gas, groundwater and surface water samples were collected and submitted for laboratory
analysis of volatile organics, semivolatile organics, metals, and pesticides. Field observations from June 15,
2000, trenching and investigation activities suggest that refuse in the western landfill is limited to the landfill’s
eastern bench.
Soil and groundwater samples were collected during installation of direct push wells and from selected trench
locations across the Site. Soil samples were collected directly at the soil/water interface. No organic or inorganic
compounds were found in concentrations exceeding SCDM benchmarks with the exception of arsenic,
dibenz(a,h)anthracene, and benzo(a)pyrene (Rees, 2001).
Lead was reported in soil samples at concentrations from 14.2 to 1,930 mg/kg. Soil samples collected from the
base of a 10-foot trench cut (SB-2) in the center of the western landfill revealed benzo(a)pyrene at 5,000 pg/kg
and dibenz(a,h)anthracene at 1,000 pg/kg (Rees, 2001). The SCDM CRSC for both compounds is 20 pg/kg (U S.
Environmental Protection Agency, 2017). The CRSC for benzo(a)pyrene was also exceeded in five samples
collected from the western portion of the landfill. Arsenic, antimony, selenium, and pentachlorophenol were
detected in Site groundwater above SCDM benchmarks. The location of elevated concentrations of
benzo(a)pyrene in soil detected during the SI, TBA, and ESI investigations is provided in Figure 4. No VOCs,
semivolatile organic compounds (SVOCs), RGBs, or pesticides were detected in any other samples above SCDM
benchmarks (Rees, 2001).
Lead was detected at 56.1 pg/L in the downgradient City Drain Canal surface water sample, collected during the
TBA, but was not detected in the upgradient sample. The CMC for lead in surface water is 65 pg/L and the CCC
for lead is 2.5 pg/L. Arsenic was also detected in the upgradient City Drain sample at 61 pg/L and in the
UTAH DIVISION OI UNVIRONMUNTAU RI SPONSI) AND RKMKDIATION
Rl.DWOOl) ROAD DUMP UTD980961502
downgradient sample at 82.8 pg/L (Rees, 2001). No other metal was reported in surface water above SCDM
benchmarks. The arsenic CMC is 340 pg/L and the lead CCC is 150 pg/L.
Arsenic was detected in multiple soil samples above the 30 mg/kg SCDM Reference Dose Screening
Concentration (RDSC) benchmark for soil and the 0.77 mg/kg CRSC. The highest concentration of arsenic in any
soil sample (43.9 mg/kg) was collected from a trench cut in the center of the western landfill (SB-2). No
background soil sample was collected during the TBA. The 1991 SI reported a background arsenic concentration
of 10.8 pg/kg. Only one TBA soil sample exceeded three times the SI arsenic background.
Arsenic was detected in many groundwater samples significantly above the MCL of 10 pg/L and the SCDM
freshwater acute exposure benchmark CCC of 150 pg/L. Arsenic was detected at two locations north of the
western landfill at 1,290 pg/L and 1,000 pg/L. Dissolved arsenic was reported in groundwater collected from the
middle of the western landfill at an estimated concentration of 1,170 pg/L. Other groundwater samples ranged
from 2.4 pg/L to 236 pg/L. Figure 5 provides the location of elevated arsenic concentrations in groundwater
detected during either the SI or the TBA. No other dissolved metals were detected in groundwater above SCDM
benchmarks (Rees, 2001; U.S. Environmental Protection Agency, 2017).
3.2.5 Portland Cement Site Investigations
The Portland Cement Superfund site is located directly south of the eastern landfill and Indiana Avenue on
approximately 71 acres. The risks posed by the Portland cement site were derived from cement kiln dust and
chromium bearing bricks that were landfilled within the Site boundaries. The dust contained several heavy metals
including arsenic, cadmium, chromium, lead, manganese and molybdenum. The contaminated soil, kiln dust and
chromium bricks were removed from the Portland Cement site from 1992 through 1997 (Howes, 2007). A
groundwater plume beneath the Portland Cement site contains elevated concentrations of arsenic, chromium,
lead, manganese and molybdenum.
Groundwater contamination is contained in the shallowest aquifer within the Portland Cement site boundaries by
a canal on the eastern boundary of the Portland Cement site known as the “City Drain,” a City sewer line on the
east and north of the site, and a storm-water ditch west of 1-215. Analytical results of semiannual groundwater
monitoring beneath the Portland Cement site indicate that the contaminant plume is contained within the Portland
Cement site boundaries (Utah Department of Environmental Quality, 2012).
3.2.6 Northwest Oil Drain Delta Sediment Investigation
The NWOD canal system begins at about 1000 North and Warm Springs Road, about 1.5 miles east of the City
Drain. The NWOD canal also flows from south to north (Figure 1). The City Drain and the NWOD join about six
miles north of the site and flow northwest toward the Farmington Bay Wildlife Management Area (FBWMA) and
the Great Salt Lake (GSL) in a shallow sediment deposition area known as the “Northwest Oil Drain Delta” (the
Delta) (Waddell et al., 2009). The NWOD is a set of canals constructed in the 1920s for the transport and
disposal of waste refinery oils, other industrial wastewater effluents, sewage, and storm water. The canals were
used extensively throughout the 1950s. There are two primary canals and several small tributary canals entering
from the industrialized area to the east. The two primary canals were used for industrial waste and a lesser canal
was used for sewage. The length of the canal is approximately 15 linear miles. A large portion of the southern end
of the canal system is no longer in use, although the remainder of the canal system still receives treated municipal
and industrial wastes (TechLaw, 2012). Both the NWOD and the City Drain flow to the Delta.
Removal actions were conducted by the Northwest Oil Drain Working Group under an Administrative Order on
Consent for approximately 8.6 miles of the oil drain in 2004 and 2005 extending from Boy Scout Drive (1300
North) downstream to the City Drain and south for 5.75 miles from the NWOD Great Salt Lake outlet. These
actions consisted of removal and disposal of sediments and sidewalls to reduce the concentration of oil, grease,
diesel-range organics, and metals such as lead and mercury (TechLaw, 2012).
An assessment of inorganic contaminant concentrations in the sediments of the Delta and on the impact of the
contaminants on the health offish and birds was published in 2009 by the U.S. Fish and Wildlife Service.
Selected data and figures from the 2009 Delta study are provided as Appendix D. Section 7.0 of the U.S. Fish

and Wildlife Service report addresses contaminant assessment of sediments in the Delta and is included in
Appendix D. A map of the Delta in relation to the Site is provided as Figure 1 and as Appendix D, Figure 7-1.
The assessment identified the average level of mercury in avian eggs to be 5.99 mg/kg dry weight, double the
Level of Concern (3 mg/kg) identified by the Department of Interior (Waddell et al., 2009). Mercury has not been
identified as a contaminant of concern from the Redwood Road Dump. The U S. Fish and Wildlife Service
collected twenty sediment samples in a grid pattern across the NWOD Delta. A map of the sediment sample
locations is provided on Figure 7-1, page 75 of the report, in Appendix D. The geometric mean concentration of
14 metals exceeded their respective Threshold Effects Concentration (TEC), out of the 15 metals for which TECs
could be identified (MacDonald et al., 2000; Waddell et al., 2009). The TEC is a consensus-based sediment
quality guideline for freshwater ecosystems developed by academia to identify a level below which harmful
environmental effects are unlikely. The 14 metals include aluminum, arsenic, barium, beryllium, boron, cadmium,
chromium, copper, lead, mercury, nickel, selenium, vanadium and zinc.
The geometric mean concentration of lead in the sediment samples (193 mg/kg) also exceeded the higher
Probable Effects Concentration (PEC) of 128 mg/kg. The Probable Effect Concentration (PEC) is a screening
level above which harmful effects are more likely than not to be observed (MacDonald et al., 2000).
Another assessment of the nature and extent of lead, mercury, total petroleum hydrocarbons-diesel range
organics, polycyclic aromatic hydrocarbons, and oil and grease in the FBWMA was published in 2012 by EPA.
The NWOD Delta includes part of the FBWMA. A copy of this report is provided in Appendix E. Twenty-five
sediments samples were collected within the FBWMA. A map of the sample locations is provided as Figure 1 in
Appendix E.
Results from the 2011 FBWMA site investigation showed that lead concentrations ranged from 28 mg/kg to 325
mg/kg within the 0-6” depth interval (Appendix E, Table 1). A map of the sample locations and their corresponding
lead and mercury concentrations is provided as Figure 2 in Appendix E. The highest lead concentrations were
noted near the mouth of the canal at sampling locations FBWMA-018-11, FBWMA-019-11, and FBWMA-020-11.
Lead concentrations at these sites were 234 mg/kg, 325 mg/kg, and 291 mg/kg, respectively. These
concentrations significantly exceed the 35.8 mg/kg TEC and the 128 mg/kg PEC (MacDonald et al., 2000). Lead
concentrations decrease as distance increases from the mouth of the canal outward past the three sampling
locations mentioned above (Waddell et al., 2009).
Mercury concentrations in the 0-6” sediment depth interval ranged from 0.077 mg/kg to 5.3 mg/kg (Appendix E,
Table 1). As seen in the lead results for sediment, the highest concentrations of mercury were noted at sampling
locations FBWMA-018-11, FBWMA-019-11, and FBWMA-020-11, near the mouth of the NWOD, with mercury
concentrations of 2.7 mg/kg, 5.3 mg/kg, and 4 mg/kg, respectively. Statistically, significant relationships were
found between the concentrations of Pb and Hg (r2 = 0.91) (Waddell et al., 2009). The source of the
contamination was not identified as a part of the study. Potential sources include the NWOD and the City Drain.
3.2.7 Site Reassessment
A Site Reassessment Report (SRA) was written in 2011 to update Site data and identify data gaps. The SRA
resulted in a recommendation to conduct an ESI to sample downgradient shallow wells and wetlands and
resample groundwater and surface water. When no downgradient wells used for drinking water were identified
between the Site and the Great Salt Lake, the ESI sample plan was modified to only sample surface water and
sediment from the City Drain Canal.
4.0 FIELD ACTIVITIES
ESI sampling was conducted on June 9, 2015 by DERR sampling personnel Neil Taylor and David Bird. The
weather was clear with temperatures in the high 80s. Field activities included the collection of seven surface
water samples and four sediment samples. This total includes a field duplicate surface water sample (RD-SW-
07). All personnel conducted sampling in Level D personal protective gear. The northing and easting of surface
water and sediment sample locations were identified using a GeoExplorer 3® and documented in the field notes.
Downstream samples were collected before upstream samples. A map of sample locations is provided as Figure
3. A one-liter polyethylene bottle was lowered into the City Drain at various locations to collect surface water

REDWOOD ROAD DUMP UTD980961502 5
samples. Clean stainless-steel spoons were used to collect sediment samples at the same location as surface
water samples when sediment was found. Water samples were preserved with nitric acid.
All samples were labeled, bagged and placed on ice in coolers and transported to DERR. Chain-of-custody forms
and sampling documentation were prepared using ERA’S Scribe software. All samples were hand delivered to
ALS Laboratories for inorganic metals analysis on June 9, 2015. Completed chain-of-custody forms are included
in Appendix F.
Field notes and photographs were taken throughout the sampling event to document sample locations, sampling
methods, and field observations. The field notes will remain in the DERR project file. Field notes and
photographs were transcribed to the Field Activities Report and provided additional details about the Site. The
Field Activities Report is included in Appendix A. The laboratory analytical data validation reports are presented
in Appendix G.
5.0 DEVIATIONS FROM THE WORK PLAN
The following are deviations from the Expanded Site Investigation Work Plan implemented for the Site (Taylor,
2015):
• The decontamination sample (RD-SW-08) was not collected because an adequate quantity of clean
stainless-steel spoons was available for sediment samples and a dipper was not used to collect surface
water samples. Field decontamination was unnecessary.
• The sample for water hardness (RD-SW-09) was not collected because water hardness (as calcium
carbonate) can be calculated from calcium and magnesium concentrations. A separate sample for
hardness measurement purposes was not necessary.
• Salt Lake City e-mailed authorization to sample the City Drain canal (Stewart, 2014). A signed Consent
For Access to Property Form was not necessary.
• Sediment sample RD-SE-05 was to be collected at the same location as RD-SW-05. Sample RD-SE-06
was to be collected at the same location as RD-SW-06. Both samples were not collected because the
sides of the City Drain canal were lined with rock at the planned sample locations and there was no
sediment to collect.
6.0 WASTE/SOURCE CHARACTERISTICS
Both west and east landfills contain municipal trash and unknown quantities of hazardous materials. Petroleum
wastes were found in four of twenty landfill soil borings that were part of a 1977 UDOT landfill waste investigation.
The investigation concluded that the majority of the organic matter in the landfill had decomposed or had been
burned, leaving mainly inorganic matter, ash, and cover material. An undefined chemical waste was found in one
of the twenty borings. The volume of the landfills is calculated at approximately 1,340,000 cubic yards (Eckoff,
1997). The landfills are not properly contained to minimize leaching of materials into the shallow groundwater.
Chromium and lead-contaminated soils were illegally placed in the central part of the eastern landfill sometime
during December of 1991 by Tool Design Engineering and Manufacturing facility personnel (Utah Division of Solid
and Hazardous Waste, 2010). Chromium concentrations in samples collected from the soil ranged from 1,240
mg/kg to 3,300 mg/kg. Lead concentrations ranged from 1,000 mg/kg to 1,800 mg/kg. The contaminated soils
were removed in 1997 and the cleanup was verified by confirmation sampling (Terracon, 1997).

7.0 GROUNDWATER PATHWAY
7.1 Hydrogeology
Precipitation that falls as rain or snow in the mountain ranges flows down the range fronts and recharges the deep
aquifer within the Salt Lake Valley. The shallow water table aquifer is generally recharged by downward
infiltration from precipitation, canals, irrigated lands and streams as well as by upward leakage from the
underlying confined aquifer. Surficial basin fill deposits within the Salt Lake Valley generally consist of a series of
Quaternary lacustrine, alluvial fan, sand dune, mud-rock flow, ash falls, glacial and floodplain sediments.
Groundwater occurs within these valley fill deposits as a complex series of aquifers. The deeper aquifer lies in
Quaternary deposits of clay, silt, sand, and gravels that are hydraulically interconnected with individual beds of
sand and gravel ranging in thickness from less than one foot to tens of feet. The maximum thickness of the
principal aquifer is greater than 1,000 feet in the northern portion of the valley. Most deep drinking water wells in
the Salt Lake Valley are completed in sediments at depths of less than 1,200 feet (Waddell et al., 1987)
There are no wells currently in use on-site. Drilling logs from the four monitoring wells installed at the Site in
1991, in addition to the well logs from the neighboring Portland Cement site reveal a lithology of clay, silt and
sand beneath the landfill (Hawkins, 1991). A soil survey of the Salt Lake area identified the soils at the Site as
dumps, Salt Air Silty Clay Loam, Loamy Borrow Pits, Sandy Terrace Escarpments, and Decker Fine Sandy Loam
(Hawkins, 1992).
Groundwater flow in the shallow aquifer although complex, due to the interaction with local surface water and
underground utility pathways, is generally to the northwest. A 42-inch sanitary sewer is buried at an average
depth of 17 feet below grade on the eastern border of the Site. The bedding material of the sewer line appears to
be removing groundwater from the shallow aquifer and routing it to the City Drain. Groundwater flow under the
eastern landfill also appears to be toward the City Drain (Hawkins, 1992).
7.2 Targets
Seventeen municipal wells from three cities are located within the four-mile target distance range from the Site.
All wells are located east or south of the Site and hydraulically upgradient (Utah Division of Drinking Water, 2017).
All three city water systems are blended with multiple groundwater and surface water sources. Approximately
4,102 underground points of diversion are located within four miles of the Site. The uses for the large majority are
for "domestic" or irrigation purposes, and most are upgradient of the Site. All downgradient wells within three
miles of the Site are 200 to 400 feet deep artesian wells drawing from the deeper, confined aquifer. The few
existing downgradient wells are privately owned, and none are presently used for residential drinking water (Utah
Division of Water Rights, 2017).
Several residential wells located 4.1 miles north and downgradient of the Site were used for drinking water until
recent private testing revealed arsenic levels above the MCL. One well was sampled by DERR personnel in 2015
as part of the investigation of a separate site. Arsenic was found at 5 pg/L. This is below the 10 pg/L MCL and
above the 4 pg/L RDSC and 0.057 pg/L CRSC SCDM benchmarks (Mitkem Laboratories, 2015).
7.3 Sample Locations
No groundwater samples were collected as a part of this investigation.
7.4 Analytical Results
There were no additional groundwater analytical results generated as a part of this ESI.
7.5 Conclusions
The Site may be the source of elevated arsenic detected as high as 1,290 pg/L in downgradient, shallow
groundwater. However, a United States Geological Survey study has determined that elevated arsenic in
groundwater under landfills may not be the results of arsenic disposed of as landfill waste. Rather, dissolved

RKDWOOD ROAD DUMP 110980961502
organic carbon in a landfill leachate plume may dissolve arsenic from arsenic-containing iron oxides in the aquifer
and bedrock. Degradation of the dissolved organic carbon in the plume removes oxygen from the water and
creates reducing conditions that favor the dissolution of iron oxides and the release of arsenic from the sediments
(Delemos et al., 2006).
Seventeen municipal wells from three cities are located within the four-mile, target-distance limit from the Site. All
are located east or south of the Site and hydraulically upgradient. All downgradient wells located within four miles
of the Site are privately owned, and none are used for drinking water.
8.0 SURFACE WATER PATHWAY
8.1 Hydrology
The Salt Lake Valley is located in the Great Basin drainage system, which is a closed system with no outlets. The
Jordan River and its tributaries form the main drainage for the valley. The Jordan River is a Class 3B stream and
discharges into the Great Salt Lake (State of Utah, 2014). The Surplus Canal and the City Drain are located in
close proximity to the Site. The City Drain is located west of 1-215 and just east of the western landfill. The
Surplus Canal is a losing stream, about 1,000 feet to the west of the Site and likely receives no contribution from
contaminated groundwater (U.S. Environmental Protection Agency, 1998). The City Drain is the primary
discharge point for Site groundwater. The NWOD and the City Drain join about six miles downgradient of the Site
and discharge into the FBWMA 10 miles north and downgradient of the Site (Hawkins, 1992).
8.2 Targets
There are no surface drinking water sources within the 15-mile target distance limit from the Site. The discharge
points for the Jordan River, the Surplus Canal, and the NWOD Delta in the Great Salt Lake are characterized by
freshwater marshes. The discharge points are within the confines of the FBWMA (Hawkins, 1992).
Approximately 50 miles of wetland frontage occur within the 15-mile target distance limit (U.S. Fish and Wildlife
Service).
8.3 Sample Locations
Sample locations were selected to characterize sections of the City Drain canal before its merger with the NWOD.
Surface water and sediment samples were co-located whenever possible. A description of sample locations and
the sampling rationale is provided as Table 1.
• Samples RD-SW-01 and RD-SE-01 were collected from the City Drain after the drain flows under Indiana
Avenue. This location is on the southern and upgradient boundary of the Site and serves as a
background sample for both surface water and sediments.
• Samples RD-SW-02 and RD-SE-02 were collected from the City Drain after it flows under 500 South.
This sample is approximately 100 yards north and downgradient of the Site.
• Samples RD-SW-03 and RD-SE-03 were collected from the City Drain as it flows parallel to Dauntless
Avenue (1000 North) and before the City Drain combines with a storm water drainage canal that runs on
the north side of 1-215.
• Samples RD-SW-04 and RD-SE-04 were collected from the City Drain at 1700 North before the City
Drain Canal merges with a branch of the Jordan River.
• Samples RD-SW-05 and RD-SE-05 were planned to be collected from the City Drain at Rose Park Lane
before the canal merges with the NWOD. All sediment had been removed from the canal banks, and no
sediment sample was collected.
• Samples RD-SW-06, RD-SW-07, and RD-SE-06 were planned to be collected from the combined flows of
the City Drain and the NWOD at approximately 3300 North. All sediment had been removed from the
canal banks, and no sediment sample was collected.

8.4 Analytical Results
8.4.1 Surface Water
As specified by the Hazard Ranking System (HRS), analytical results from field samples are typically compared to
analytical results from background sample(s) and to Sample Quantitation Limits (SQL) for determining an
observed release. The criteria for establishing an “observed release” is as follows:
• If the background concentration is not detected, an observed release is established when the sample
concentration equals or exceeds the sample quantitation limit; or
• If the background concentration equals or exceeds the detection limit, an observed release is established
when the sample concentration “significantly exceeds” the background concentration. Generally,
“significantly exceeds” is defined to be situations where the sample concentration exceeds the
background concentration by at least three times (U.S. Environmental Protection Agency, 1990).
A summary of the inorganic metal concentrations detected in surface water samples is provided in Table 2. The
concentration of aluminum (1,290 pg/L) in the upgradient sample (RD-SW-01) significantly exceeds the 750 pg/L
CMC and the 87 pg/L CCC. However, the concentration of aluminum (258 pg/L) in the first downgradient sample
after the Site (RD-SW-02), although still exceeding the CCC, is significantly less than the upgradient sample. The
concentration of aluminum at Dauntless Avenue (363 pg/L), 1700 North (124 pg/L), and Rose Park Lane (96.4
pg/L) exceed the CCC.
The concentration of iron (2,130 pg/L) in the upgradient surface water sample also significantly exceeds the CMC
of 1,000 pg/L. However, downgradient iron concentrations are below SCDM benchmarks. Lead was detected in
the upgradient surface water sample at a concentration of 12.8 pg/L. This is above the 2.5 pg/L CCC benchmark.
However, lead concentrations in all downgradient samples are below the CMC and CCC. No other inorganic
metal concentrations exceed an SCDM benchmark (U.S. Environmental Protection Agency, 2017).
8.4.2 Sediment
A summary of inorganic metal concentrations detected in canal sediment samples is provided in Table 3.
Potassium was detected at 4,590 mg/kg in sediment collected from the City Drain at Dauntless Avenue and 1-215.
This exceeds by over three times the 1,480 mg/kg concentration of potassium detected in the background
sediment sample. Silver was found at 1.5 mg/kg in sediment collected at 500 South and 1-215 and was found at
1.3 mg/kg at Dauntless Avenue and 1-215. These exceed by over three times the background concentration of
silver detected in the background sample (0.2 mg/kg). A TEC or PEC has not been determined for either
potassium or silver. Both upgradient and downgradient concentrations of arsenic, copper, and lead exceed the
sediment TEC. The concentration of copper and lead remain elevated above the TEC at the last sample point
(1700 North and 1-215).
8.5 Conclusions
Although the concentration of aluminum, cadmium, copper, and lead are above environmental benchmarks in
both surface water or sediment, none significantly exceeds the background sample concentration and thus, none
of the releases can be attributed to the Site. Only aluminum was found in downgradient surface water samples
above an SCDM benchmark. Only potassium and silver concentrations in downgradient City Drain sediment
significantly exceed the upgradient sediment metal concentrations. No metal was both present in a concentration
exceeding a SCDM benchmark or sediment toxicity benchmark and present at a concentration at least three
times background. Thus, no releases of concern can be tied to the Site from this study. Previous studies have
shown a release of lead to the City Drain both above a SCDM benchmark and significantly above background
concentrations (Rees, 2001).

9.0 SOIL EXPOSURE PATHWAY
9.1 Geology
The Wasatch Front is underlain by the active Wasatch Fault system. This system is a major geologic structure
that extends generally north and south for a distance of some 210 miles. Vertical movement along this fault
system exceeds three miles. The Wasatch Front is subdivided into several valleys (Waddell et al., 1987).
The Site is located in the Jordan River Valley of the Great Basin Section of the Basin and Range Physiographic
Province. The Jordan River Valley is bounded by the Wasatch Mountains to the east, the Oquirrh Mountains to
the west, the Traverse Mountain Range to the south, and the Great Salt Lake to the north. Basin-fill deposits
were eroded from the Wasatch and Oquirrh Mountains and deposited in the Salt Lake Valley. The general
stratigraphy of the area is characterized by several hundred to several thousand feet of unconsolidated and semi-
consolidated basin-fill deposits. Mountain streams and historical lakes carried most of the sediment into the basin
and ancient Lake Bonneville. The fine-grained sediments were deposited in deeper portions of Lake Bonneville.
The coarser-grained sediments were deposited along the margins of ancient Lake Bonneville near the mountains
as its level eventually receded to its present level as the Great Salt Lake (Waddell, et al., 1987).
9.2 Targets
The Redwood Road Dump is enclosed by chain link and barbed wire fences. This barrier prevents unauthorized
vehicle access (Taylor, 2010). There is no on-site population or residences. There are no schools or day cares
located within 200 feet of the site. There is a population of 130,095 within the four-mile Target Distance Limit
(U S. Census Bureau, 2010). Table 4 lists the target population within various distances. Both western and
eastern landfills are fenced. Two means of access are available to the eastern landfill; one is from the north
through a gate that is locked at night, and one from the south through a road barrier. Approximately 50 miles of
wetland frontage occur within the 15-mile target distance limit (U S. Fish and Wildlife Service).
9.3 Sample Locations
No soil samples were collected during the ESI. Only limited subsurface soil hazardous constituent analysis has
been conducted for the eastern landfill.
9.4 Analytical Results
There are no new analytical results for the soil exposure pathway. Previous investigations summarized in Section
3.2 have identified a variety of organic and inorganic contaminants present in Site soils because of historical use
as a municipal landfill including concentrations of barium, calcium, chromium, copper, iron, mercury, nickel,
sodium, and zinc over three times that of the background sample. Lead was found in the subsurface soils as high
as 2,610 mg/kg. Benzo(a)pyrene was detected in the soil as high as 5,000 pg/kg and dibenz(a, h)anthracene
detected as high as 1,000 pg/kg. The benchmark for benzo(a)pyrene and dibenz(a, h)anthracene is 20 pg/kg.
9.5 Conclusions
Although a variety of both organic and inorganic contaminants is present in surface soils, the Site is fenced and
well maintained. No exposure to Site contaminants is anticipated when the Site is controlled under current
operating practices.
10.0 AIR EXPOSURE PATHWAY
10.1 Meteorology
The Salt Lake Valley is characterized as being semiarid. The normal maximum temperature ranges from 37.0° F
in January to 93.7° F in July. The normal minimum temperature ranges from 19.7° F in January to 61.8° F in July.
The average annual rainfall is 15.31 inches per year with a normal monthly high of 2.21 inches in April and a
io

normal monthly low of 0.72 inches in July. The average annual snowfall is 58.0 inches. The estimated pan
evaporation is a 3.91 inches per year (Western Regional Climate Center). The winds are predominantly from the
south and southeast and have a mean speed of four to five miles per hour (Ashcroft et al., 1992).
10.2 Targets
Table 4 lists the target population within various distances. Both western and eastern landfills are fenced. Two
means of access are available to the eastern landfill; one is from the north through a gate that is locked at night,
and one from the south through a road barrier. The landfills are covered to various depths by soil. There is not
an engineered landfill cap (Eckoff, 1997).
10.3 Sample Locations
There were no additional samples collected beyond the soil gas samples collected during prior investigations
described in Section 3.2.
10.4 Analytical Results
No additional analytical results were generated by this ESI.
10.5 Conclusions
Methane, as the result of the decomposition of municipal waste, is the only airborne contaminant identified by
prior investigations as a potential exposure hazard. Methane was not identified in concentrations that should be
an explosion or health hazard under current operating conditions at the Site.
11.0 DATA QUALITY
Sampling was conducted according to methods outlined in the DERR Quality Assurance Program Plan for
Environmental Data Operations (QAPP) of November 2014 and other relevant EPA guidance documents.
Samples were kept in the possession of the DERR project manager and strict chain of custody was maintained
during the sampling event. All collected samples were kept on ice and cooled to 4° C. Water samples were
preserved by nitric acid to a pH below 2. All sample information was logged into a field notebook, and collected
samples were photo documented on-site. EPA chain-of-custody forms were completed using the Scribe software
and accompanied the sample shipments to the laboratory. Copies of the chain-of-custody forms are included in
Appendix F. All samples were hand carried to the laboratory the day of collection and analyzed within 21 days of
collection.
Samples RD-SW-03 and RD-SE-02 were collected as double volume laboratory duplicates for QA/QC purposes.
Surface water sample RD-SW-07 was collected as a field duplicate of sample RD-SW-06. Both samples
identified the same metals in similar concentrations. The relative percent difference of analyte concentrations was
below the 30 percent rejection limit.
A validation package was prepared by Weston Solutions for the water and sediment samples (Appendix G). Data
were determined to be acceptable according to EPA Data quality concerns, adjustments, and qualifications noted
in the review are summarized in Table 5. The data validation package was reviewed by the project manager and
the data was transcribed into Tables 2 to 3. The Data Quality Objectives for the Site, as presented in Table 6 of
this report, were met.
12.0 SUMMARY
The Site was the primary landfill for Salt Lake City from 1923 until 1962, when it was closed to public dumping. I-
215 was constructed through the center of the Site in 1988 creating an eastern and western refuse pile. It is
believed that waste characteristics at the Site include municipal wastes such as household, commercial, industrial
UTAH DIVISION OF ENVIRONMENTAL RESFONSE AND REMEDIATION

and organic materials. The City Drain Canal bisects the site. Water from the canal eventually enters the FBWRA
approximately 10 miles downstream of the site. Approximately 50 miles of wetland frontage occur within the 15-
mile target distance limit.
The Site has undergone a series of studies to identify potential Site contaminants and off-site effects. Above
background concentrations of barium, calcium, chromium, copper, iron, lead, mercury, nickel, sodium, zinc,
benzo(a)pyrene, dibenz(a, h)anthracene, and arochlor 1260 were detected in surface soil. However, there is no
on-site population or residences at the Redwood Road Dump. There are no schools or day cares located within
200 feet of the site. No exposure to contaminants is anticipated at the Site when the Site is appropriately
maintained and controlled under current operating practices.
Arsenic, antimony, selenium, and pentachlorophenol were found in Site groundwater above SCDM benchmarks.
However, there are no downgradient wells used for drinking water within four miles from the Site. Arsenic levels
in surface water increase from a background concentration of 54.8 pg/L to a concentration of 89.5 pg/L
immediately downstream of the Site. Arsenic concentrations decrease after that point to a concentration of 15.4
pg/L at the Sewer Canal.
Elevated concentrations of lead have been found in sediments of the FBWRA. The focus of this ESI was to
determine if surface water and groundwater flowing to the canal from the Site may be a source of contaminants
flowing to the FBWRA. Most inorganic metal concentrations in water collected from the City Drain Canal as a part
of this ESI were higher in the upgradient sample than the downgradient sample. Both upgradient and
downgradient inorganic metal concentrations of aluminum exceed an SCDM benchmark.
Both upgradient and downgradient surface water contains lead at a concentration exceeding an SCDM
benchmark. Both upgradient and downgradient sediments contain arsenic, copper, lead, and cadmium in
concentrations that exceed an environmental benchmark. Thus, no significant releases of metals to surface water
or sediment can be attributed to the Site at this time.

A serial dilution analysis was performed on
sample MH0AA2. Results were not assessed
unless the native concentration was
nominally 50* the MDL. The %D for arsenic
exceeded the control limit at 11%; therefore,
arsenic in the samples, all detects, was
qualified as estimated, “J.” The remaining
percent differences (%Ds) were within the
control limit of <10%.

A laboratory duplicate analysis was
performed on sample MH0AB0. The antimony
results exceeded the control limit of ± the
reporting limit (RL) and the lead (78%) and
magnesium (46%) RPDs exceeded the
control limit; therefore, results for these
analytes were qualified as estimated, “J,” for
detects and, “UJ,” for nondetects in the
samples.

Sediment
A matrix spike analysis was performed on
sample MH0AB0. Results were not assessed
when the native concentration exceeded the
spike amount by 4* or more. Recoveries
were above the control limit; therefore,
detects for these analytes in the samples
were qualified as estimated with a potential
high bias, “J+.” The antimony recovery was
below the control limit at 25%; therefore,
antimony detected in the samples was
qualified as estimated with a potential low
bias, “J-.” As the post digestion spike
recovery for antimony was acceptable,
nondetected antimony in sample MH0AB2
was qualified as estimated, “UJ,” instead of
beinq rejected.

Optimization of Sample
Design
Lead in surface water, has
been detected at a level
significantly exceeding
SCDM screening levels.
Arsenic has also been
detected in surface water at
about half the SCDM
benchmark. No surface
water or sediment samples
have been collected from
downgradient surface
waters to determine
potential threats to
downgradient sensitive
environments. Total water
hardness has not been
determined to permit
accurate determination of
SCDM hardness based on
environmental benchmarks
Are Site contaminants present
in surface water or sediments
at levels that could pose a
threat to downgradient
sensitive environments?
Field and laboratory
analytical results from
surface water and sediment
upgradient and
downgradient samples will
form the basis for making
subsequent decisions.
Surface water total
hardness analytical results
will be used to calculate
SCDM hardness based
environmental benchmarks.
Analytical results from
surface water will be
compared to SCDM
environmental benchmarks.
Analytical results from
sediment samples will be
compared to background
concentrations to determine
if an “observed release” of
contaminants is present.
Surface water and
sediment samples will be
collected upgradient of the
Site and downgradient of
the Site at locations before
and after the City Drain
merges with several
downgradient canals
before entering sensitive
environments at the Great
Salt Lake. Co-located
sediment samples will also
be collected.
In general, sample
results will be compared
to background samples
and to SCDM
benchmarks to determine
if potential
environmental threats
exist. Contaminant
concentrations in
upgradient and
downgradient samples
will be used to further
identify the extent of
contamination.
Judgmental sampling will be
used to bias samples toward
more potentially
contaminated areas.
Statistical sampling will not
be used and the tolerance
limits on decision errors will
not be calculated. All
analytical data will be
reviewed, verified and
validated to ensure data are
acceptable for the intended
use.
Sample locations may be
adjusted based on utility
clearances or other field
factors. Site maps,
updated with the results
from previous sample
studies, will be used to
determine the number and
location of potential
source sample locations.
The surface water sample
used for determining total
water hardness will be
collected at a location that
accurately represents the
quality of water flowing
from the Site into
sensitive environments.

FIELD ACTIVITIES REPORT
FIELD ACTIVITIES REPORT
SURFACE WATER AND SEDIMENT SAMPLING
For the Redwood Road Dump
CERCLIS ID UTD980961502
June 9,2015
On June 9, 2015 Utah Department of Environmental Quality Division of Environmental Response and
Remediation (DERR) personnel coordinated groundwater, sediment and surface water sampling in
connection with the investigation of the Redwood Road Dump (Site). This report describes the sampling
effort.
Sampling Conditions
DERR sampling personnel included Neil Taylor and David Bird. The weather was clear with
temperatures in the high 80s. Photographs document the sample locations. All personnel conducted
sampling in Level D personal protective gear. The northing and easting of surface water and sediment
sample locations were identified using a GeoExplorer 3® and documented in the field notes. All samples
were labeled, bagged and placed on ice in coolers and transported to DERR. All samples were hand
delivered to AES Laboratories for metals analysis on June 9, 2015.
1
RD-SW-06/07
This sample was collected on West Center Street in North Salt Lake from the City Drain. The canal
banks were very steep with rock placed on the canal banks. No sediment was available to sample. This
location is northeast and downstream of the City Drain Canal merger with the Sewage Canal and
Northwest Oil Drain.
Figure 1 - Looking West
2
RD-SW-04
The sample was collected by taking the 2100 South exit off 1-215 and then proceeding east along Rose
Park Lane to 2200 West. There was very little, if any, flow in the canal at this location and banks were
steep. This location is before the merge with the branch of the Jordan River. Water looked stagnant and
the canal banks were lined with rock with no sediment available to sample.
Figure 2 - Looking West
3
RD-SW-04/SE-04
This is after the merge with the Jordan River branch, but appeared to have little difference from after the
merge. There was very little flow and the water was stagnant. Canal banks were very steep and the
sampler had to be lowered and retrieved by rope. A small amount of sediment was sampled.
4
RD-SW/SE-03
This City Drain sample location is at the east end of Dauntless Avenue on the south side of the avenue
on the north bank of the City Drain. Water was flowing a bit more here and the water appeared more
clear. A surface water laboratory duplicate was also collected here.
5
SW/SE-02
This location is on the west side of 1-215 along 500 South and is just east of a city impound lot. The
mud here was very dark in color and smelled of petroleum. Sediment was dark and sticky.
6
RD-SW/SE-01
This is the upgradient sample location just after the City Drain Canal has past under Indiana Avenue.
The sample was collected on the south bank of the canal on property used by the city to store equipment
and salt.

APPENDIX D
ASSESSMENT OF CONTAMINANTS IN THE WETLANDS
AND OPEN WATERS OF THE GREAT SALT LAKE, U.S.
FISH AND WILDLIFE SERVICE, SECTION 7
U.S. Fish & Wildlife Service
Assessment of Contaminants in the
Wetlands and Open Waters of the
Great Salt Lake, Utah
1996-2000
7.0 CONTAMINANT ASSESSMENT OF SEDIMENTS IN THE NORTHWEST
OIL DRAIN "DELTA", FARMINGTON BAY, 2000
7.1 Introduction
The Northwest Oil Drain (NWOD) was built in the early part of the 20th century as part of the Salt Lake
City’s irrigation and flood water control system and to transport waste waters from heavy industries
located in the northwest quadrant of the city. Currently, flows are a combination of return flows from
canals originally diverted from the Jordan River, storm waters, treated wastewater effluents from the Salt
Lake City Wastewater Treatment Plant (SLC WWTP) and treated wastewaters from several refineries still
in operation in the area. Prior to the implementation of controls under water quality regulations beginning
with the 1972 Water Pollution Control Act, the NWOD carried untreated wastewaters from a variety of
industries in the northwest quadrant, including the refineries, feed lots, tanneries, metal fabricating and
plating operations, chemical manufacturing plants, and other “heavy industries.” The former name of the
NWOD, still currently in use, is “the Sewage Canal.”
The NWOD enters the Great Salt Lake within one of the most intensely managed and productive
waterfowl habitats on the GSL, the Farmington Bay Waterfowl Management Area (FBWMA) which is
owned and operated by the Utah Department of Natural Resources Division of Wildlife Resources
(UDNR- DWR). The outlet of the NWOD forms a delta of sediments which reach out several kilometers
into the bay, and is located between two of the main waterfowl management impoundments of the
FBWMA, the Turpin Unit to the north and the Crystal Unit to the south (Figure 7-1). Although the
shoreline of the GSL varies considerably depending on lake level, the delta is typically shallowly
inundated over much of its area, and is vegetated with emergent and submerged aquatic wetland plants.
There are typically a large number and variety of avian species foraging and nesting in the area, with
large populations of American avocets, black-necked stilts, white-faced ibis, and American coots foraging
in the sediments.

location of sediment samples (and transects) within the NWOD delta.

in operation in the area. Prior to the implementation of controls under water quality regulations beginning
with the 1972 Water Pollution Control Act, the NWOD carried untreated wastewaters from a variety of
industries in the northwest quadrant, including the refineries, feed lots, tanneries, metal fabricating and
plating operations, chemical manufacturing plants, and other “heavy industries.” The former name of the
NWOD, still currently in use, is “the Sewage Canal.”
The NWOD enters the Great Salt Lake within one of the most intensely managed and productive
waterfowl habitats on the GSL, the Farmington Bay Waterfowl Management Area (FBWMA) which is
owned and operated by the Utah Department of Natural Resources Division of Wildlife Resources
(UDNR- DWR). The outlet of the NWOD forms a delta of sediments which reach out several kilometers
into the bay, and is located between two of the main waterfowl management impoundments of the
FBWMA, the Turpin Unit to the north and the Crystal Unit to the south (Figure 7-1). Although the
shoreline of the GSL varies considerably depending on lake level, the delta is typically shallowly
inundated over much of its area, and is vegetated with emergent and submerged aquatic wetland plants.
There are typically a large number and variety of avian species foraging and nesting in the area, with
large populations of American avocets, black-necked stilts, white-faced ibis, and American coots foraging
in the sediments.

Contaminants Assessment
Beginning in the late 1990’s, the U.S. EPA and the Utah Department of Environmental Quality (UDEQ)
began conducting remedial investigations of the NWOD under the Comprehensive Environmental
Response, Liability and Compensation Act (CERCLA). These investigations came to the Service’s
attention after much of the sampling for the 1996-1997 GSL Wetlands Contaminant assessment had been
completed. However, based on data that had been collected in relevant locations (summarized below, and
shown in Figure 7-2), the Service recommended that the NWOD remedial investigation include the
submerged portion in Farmington Bay to address avian exposure to contaminants in the delta and
characterize risks to avian populations. The study detailed in this section was undertaken by the Service
in order to gather data to help in this process. However, the regulatory agencies declined to extend the
investigation due to a variety of factors. The upstream segments of the NWOD canal were cleaned up
during approximately 2002 - 2005, but the delta of the NWOD remains unaddressed to date.
7.2 Study Location and Methods
Twenty sediment sampling locations were chosen for this investigation and sampled in 2000. Eighteen of
the sampling points were located at the mouth of the NWOD where it empties out into Farmington bay
near the southwest end of the impoundment dike between the Crystal Unit (to the south) and the Turpin
Unit (to the north) in the FBWMA (Figure 7-1). Two additional samples were located upgradient of the
shoreline of Farmington Bay as it existed in 2000, within the Turpin Unit. These samples were located to

characterize contamination that may have been deposited in the Turpin Unit during the early 1980’s,
when several years of historically high precipitation had resulted in flooding of the GSL shoreline. The
samples were arranged in transects that ran parallel to the shoreline and extended out into Farmington
Bay. The first transect (T-l) included the two points within the Turpin Unit, and the second (T-2) was the
first transect located within Farmington Bay. A total of six transects, spaced approximately 500 meters
apart, extended about 2.5 km into Farmington Bay. Sediments in the four shore-most transects (T-l
through T-4) were located under less than 30 cm of water; these were sampled with decontaminated
stainless steel scoops according to procedures outlined in Section 3. The last two transects (T-5 and T-6)
were under approximately 1.0 - 1.5 meters of water, and were sampled with a stainless steel ponar dredge
from a canoe. All samples were collected into chemically clean borosilicate glass jars, and handled,
transported and stored as described in Section 3. Samples were analyzed for 19 metals, 25 organochlorine
compounds (including total PCBs); and 25 polynuclear aromatic hydrocarbons (PAHs) including both
non-alkylated and alkylated PAHs. Two isomers of tetrachlorobenzene (TCB; 1,2,3,4- and 1,2,4,5-
isomers), were also included in the analysis. Analytical laboratories and methods are described in Section
3.
Analytical results were compared with the freshwater Consensus-based Sediment Screening Guidelines
(CBSSG) threshold effect concentrations (TECs) and probable effect concentrations (PECs) used to
evaluate the GSL wetland sediments. (MacDonald et al. 2000) and see Section 4.1). Concentrations of
selenium were evaluated against the sediment guidelines in (National Irrigation Water Quality Program
1998) because these guidelines directly address adverse effects to avian species. Concentrations of Al, Ba,
Mn, and V were compared with concentrations identified in “SQuiRT” (Screening Quick Reference
Tables) produced by the National Oceanic and Atmospheric Administration (NOAA;(Buchman 1999).
Ecologically-based screening concentrations could not be identified for Be and B, so concentrations of
these elements were compared with mean “background” concentrations in western U.S soils (Shacklette
& Boemgen 1984) as a way of roughly identifying elevated concentrations compared with these
“background” values. No reference values were identified for Fe, Mg, Mo and Sr. For organics,
available TEC and PEC concentrations (MacDonald et al., 2000 and NOAA, 1999) were used as
screening benchmarks. Although these benchmarks are not available for all of the compounds that were
analyzed, they are available for constituents that are typically of greatest concern for ecological toxicity.
Since organic constituents tend to co-occur with each other, we believed that elevated concentrations of
compounds with screening concentrations would tend to “drive” the evaluation, so no attempt was made
to identify additional benchmarks for compounds not addressed by the CBSG or SQuiRT references.
7.3 Results and Discussion
Trace Elements-
All data from the metals analysis in the Oil Drain Delta sediments are presented in Appendix Table D-l.
All elements but Hg, Mo and Se were detected in every sample, with Mo the least frequently detected, in
less 50% of the samples.
The geometric means of 14 metals exceeded their respective TECs, out of the 15 metals for which TECs
could be identified (Table 7-1). Only the geometric mean concentrations of Cr, Mn and Vn did not
exceed these lower benchmarks. All 20 samples exceeded the TECs for a number of metals of concern
including As, and Pb; 19 of the 20 samples exceeded the TEC for mercury (Table 7-1). The geometric
mean concentration of lead (Pb) exceeded the higher threshold PEC, and a high frequency of samples
exceeded the PECs for Pb and Cu. Seven of the 20 sediment samples exceeded the PEC for Hg.
In addition to the number of exceedences of the sediment benchmarks, the spatial distribution of
contaminant concentrations was also of interest. Copper, Pb and Zn collectively tended to have the
highest concentrations from Transect 3 (T-3) outward (Figure 7-3); Hg exhibited the same trend (Figure
7-4).

Contaminants Assessment
Organics-PCBs, DDTs, other chlorinated hydrocarbons
All data from the analysis of organic constuents in the NWOD Delta sediments are presented in
Appendix Tables D-2 (OCs and PCBs), D-3 (non-alkylated PAHs) and D-4 (alkylated PAHs).
Total PCBs and DDTs were detected in all 20 samples. Total PCB (t-PCB) concentrations ranged from
0.043 - 5.55 mg/kg (geometric mean 0.293 mg/kg), with 19 of 20 samples exceeding the TEC of 0.060
mg/kg and five exceeding the PEC of 0.680 mg/kg. Echoing the contaminant distribution observed for
trace metals, the highest detected concentrations of total PCB occurred the furthest off-shore in Transect 6
(Figure 7-5).
All six isomers of DDT were detected in NWOD delta sediments, with the isomers of DDD (o,p’-DDD
and p,p ’-DDD) the most frequently occurring, in 18 of 20 samples (Table 7-2). Maximum detected
concentrations of all six isomers exceeded their respective PECs, and geometric mean concentrations of
o,p -DDD and p,p ’-DDE exceeded their TECs (0.005 mg/kg and 0.003 mg/kg, respectively). In contrast
to total PCB concentrations, which had a distinct peak in Transect 6 (furthest off-shore), concentrations of
DDTs were more evenly distributed throughout the sampling grid (shown as total DDT in Figure 7-6).
Non-DDT organochlorines were also detected in NWOD delta sediments, with chlordanes (alpha
chlordane, gamma chlordane, cis- and trans- isomers of nonachlor) present at the highest concentrations
in this group. This was similar to trends observed in wetland sediments around the GSL during the 1996-
1996 contaminants assessment, but concentrations tended to be higher in the NWOD delta. Geometric
mean concentrations of alpha chlordane slightly exceeded the TEC (0.0033 mg/kg vs. the TEC of 0.0032
mg/kg). Spatial trends for these compounds were consistent with that seen for other constituents
analyzed, with the highest concentrations being present in the furthest off-shore transect, T-6 (Table 7-3).
Polynuclear aromatic hydrocarbons (PAHs)
Both alkylated and non-alkylated PAHs were analyzed in NWOD delta sediments. This was done to
provide data for a “fingerprint” analysis of PAHs, which can provide information as to the origin and/or
source of these compounds, but this analysis was not performed. Complete data from these analyses are
provided in Appendix Tables D-3 (alkylated PAHs) and D-4 (non-alkylated PAHs). Howver, sediment
screening benchmarks are only available for non-alkylated PAHs, so only these compounds are discussed
below. Total PAHs (t-PAH), calculated as the summed concentration of all PAHs (using a value of V2 the
detection limit for samples with non-detected concentrations) were also evaluated. Two isomers of
tetrachlorobenzene (TCB) were also evaluated; sediment screening benchmarks are not available for these
compounds either.
As expected, PAHs were widely distributed in the Oil Drain delta with all 25 of the non-alkylated PAHs
analyzed detected in at least one sample and with 16 of the 25 detected in all sediment samples. At least
one PAH was present >TEC in each of the 20 samples. Nine PAH compounds had mean concentrations
in at least one transect that exceeded their respective TECs and the mean concentration of
dibenz(a,/z)anthracene exceeded the PEC in one transect (T-5) (Table 7-4),. Three PAH compounds, and
t-PEC had maximum detected concentrations > PEC in at least one sample. While PAH concentrations
exceeded TECs throughout the sampling grid, the spatial distribution concentrations was similar to that
observed previously, the highest concentrations detected at the off-shore edge of the grid (Figure 7-7).
Conclusions and Recommendations
The majority of trace elements of concern (e.g., Hg, Cu, Pb, Zn) as well as chlorinated OCs and PAHs
were detected in NWOD delta sediments at levels that exceeded threshold sediment toxicity
concentrations for individual compounds. These concentrations are known to adversely impact both
sediment-dwelling organisms and birds that forage on them.

Figure 7-7. Spatial distribution of total (summed) non-alkylated PAH concentrations
(mg/kg dry weight) in sediments, Northwest Oil Drain Delta of the Great Salt Lake, 2000.
Threshold effect concentration (TEC) =1.61 mg/kg; probable effects concentration (PEC)
=22.8 mg/kg.
While sediment TECs are commonly interpreted as conservative because adverse effects are “not
expected below them, an evaluation of the individual studies that form their basis indicates that adverse
effects have been observed at or even below these thresholds in certain cases (D. Wall, USFWS, personal
communication). Additionally, individual TECs/PECs do not address cumulative (additive or
synergistic) toxicity. We found mean concentrations of 14 of 15 metals, and organic compounds
including total PCBs, DDT isomers, chlordane and several PAHs (including total PAH) to be present
above TECs, and nearly half of the samples had levels of some of the most toxic constituents (Pb, Hg, t-
PAH) exceeding “probable” effects levels. Cumulatively, these data suggest that sediment-dwelling
invertebrate and plant communities could be impaired in the NWOD delta. These impairments can lead
to a decrease in abundance and diversity of food items for avian fauna that occur in the FBWMA, where
the NWOD delta is located.
However, despite possible impairment, sediment-dwelling organisms and plants are present in the NWOD
delta, because some of the most abundant species in the area, which are adapted to the difficult
environmental conditions of the GSL’s estuarine wetlands (e.g., high salinity, low oxygen, high
temperatures) are also pollutant tolerant. Avian usage of food resources in the NWOD delta is also a
function of the surrounding, less polluted habitats in the FBWMA, which are managed specifically for
84 GSL Wetlands & Open Waters 1996-2000
Contaminants Assessment
avian productivity. These conditions create a pathway for birds to be exposed to contaminants in the
NWOD delta both through consumption of food items (e.g., the gut contents of macroinvertebrates,
sediments attached to roots and other plant matter) and through consumption of sediments adhering to
these food items. This “incidental” sediment ingestion can range from 3 - 10% of total dietary intake
depending on species (Hui & Beyer 1998; Beyer et al. 2008).
The highest concentrations of almost all constituents were observed in the farthest off-shore transects.
Thus, while the “nature” of contamination in the NWOD delta is better characterized as a result of this
study, the “extent” of the contamination is not. Because the location of the GSL shoreline fluctuates
greatly with small changes in lake elevation, the areas around the farthest transects may be exposed at
lower lake levels, subsequently increasing exposure risk to benthic foraging birds.
Mercury concentrations in avian eggs collected in the Crystal Unit in 1996-1997 (discussed in Section
4.4) seem to indicate that birds exposed to sediments in this area would have increased risk of
ecologically adverse effects. Elevated t-Hg concentrations were observed in black-necked stilt and
American coot, both of which are highly sediment exposed and are commonly observed in the NWOD
delta. However, in our follow-up investigation, which addressed a piscivorous species, Forsters’ tem (see
Section 6), elevated mercury concentrations were not observed. We believe this indicates that mercury
uptake in the Farmington Bay wetlands does not occur through the food-chain (i.e., biomagnification
through successive trophic levels) but is instead more an issue of direct sediment exposure.

1.0 Introduction
This document serves as die technical memorandum for die site investigation that took place on
September 19,2011 at the Farmington Bay Waterfowl Management Area (FBWMA) in support
of the Northwest Oil Drain Superfund Site. Figure 1 shows the sampling locations for the 2011
site investigation. The study was designed to determine the nature and extent of the
contaminants of potential concern (COPC) within sediments of the FBWMA. The investigation
included the assessment of COPCs in the flowing portion of the Northwest Oil Drain and non­
flowing portion of the Great Salt Lake. All samples were collected per the procedures set forth
in the Sampling and Analysis Plan/Quality Assurance Project Plan for the Northwest Oil Drain
dated September 2011 (SAP). Any deviations from the plan are identified in the body of this
document. The COPCs for the site are also identified in the SAP (ESAT 2011) and consist of
lead, mercury. Total Petroleum Hydrocarbons-Diesel Range Organics (TPH-DRO), Polycyclic
Aromatic Hydrocarbons (PAHs), and Oil and Grease (O&G). Action Levels for TPH-DRO (100
mg/kg) and O&G (300 mg/kg) were previously proposed by the Northwest Oil Drain (NWOD)
working group for other portions of the canal and accepted by the Environmental Protection
Agency and the State of Utah (Stantec Consulting Inc., 2003).
The goals of this sampling event were to provide data to determine the nature and extent of
metals and petroleum-related contamination in the FBWMA and to allow comparison of these
data to clean-up criteria established for the NWOD and risk-based screening benchmarks for
benthic invertebrates. This Technical Memorandum addresses these goals and also aims to
determine the relationship between historical and current data where sampling locations are co­
located and to determine if tire extent of contamination was indeed captured during the 2011 site
investigation. Historical data were obtained from Camp Dresser Mckee (CDM) and United
States Fish and Wildlife Service (USFWS). The 2011 data set was collected by the United States
Environmental Protection Agency (EPA) and Region 8 Environmental Services Assistance Team
(ESAT).
1.1 Background
The NWOD is a set of canals constructed in the 1920s for the transport and disposal of waste
refinery oils, other industrial wastewater effluents, sewage, and storm water. The canals were
used extensively throughout the 1950s. There are two primary canals, several small tributary
canals entering from the industrialized area to the east, as well as larger tributaries (e.g., City
Dram) from the south. The two primary canals were used for industrial waste, and a lesser ranal
which was used for sewage. The NWOD begins near downtown Salt Lake City, and proceeds
northwesterly toward the FBWMA and the Great Salt Lake (GSL). The length of the canal is
approximately 15 linear miles. A large portion of the southern end of the canal system is no
longer in use, although the remainder of the canal system still receives treated municipal and
industrial wastes.
The Rose Park Subdivision was constructed on top of a section of the southern end of the mnnl
system. Approximately 35 homes and a school exist directly above the old canal. The NWOD
surfaces northwest of Rose Park, where it is an ephemeral open ditch referred to as the "non­
2
flowing" or abandoned section. There is too little water in this section of the canal to generate a
constant flow; however, water ponds in places during wet periods. The Salt Lake City municipal
water treatment plant effluent discharges into the NWOD at approximately 1500 North and 1200
West streets. At this point the NWOD has year-round flow. This is referred to as the "flowing"
section of the NWOD. Various surface drains discharge into the NWOD, so that the water body
gains volume as it flows towards the Great Salt Lake. Based on information contained in the
expanded site characterization (CDM, 1999), the sludge from the oil drain contained heavy
metals, including arsenic, chromium, copper, lead, mercury, selenium, and numerous organic
compounds including PAHs.
Regulatory Actions
Removal actions were conducted by the NWOD Working Group under an Administrative Order
on Consent for approximately 8.6 miles of the oil drain in 2004 and 2005. These actions
consisted of removal and disposal of sediments from the upper 2.2 miles extending from Boy
Scout Drive downstream to die city drain and removal and side-cast of sediments from
approximately 3000 feet north of the concrete bridge at FBWMA upstream for 5.75 miles. The
overall objective of these removal actions was to;
• Minimize current risk to human health and the environment from sediments
• Restore the conveyance capacity of the NWOD
Design work for sediment removal from Segments 2 and 3 is on-going. The recommended
clean-up levels for TPH-Diesel Range Organics (DRO) is 100 mg/kg and 300 mg/kg for O&G.
Action Levels for TPH-DRO and O&G were previously proposed by the NWOD working group
for other portions of the canal and accepted by the Environmental Protection Agency and the
State of Utah (Stantec Consulting Inc., 2003). An additional objective is to reduce total lead •
concentrations as stated in die “Action Memorandum ”(EPA, 2003a).
Current Land Use
The land surrounding the southern end of the NWOD is industrial or residential. After the
NWOD passes the 1-215 and Redwood Road intersection, land use becomes predominandy
agricultural. Plowed fields and livestock grazing are visible on both sides of die NWOD. As the
NWOD approaches the Great Salt Lake, it passes through land previously owned by a duck chib,
which has since been turned over to the Utah Division of Wildlife Resources. The duck club
historically managed the area for wildlife, waterfowl production, and hunting. Upon leaving the
duck chib property, the NWOD enters FBWMA and flows 15 miles or more before reaching the
Great Salt Lake. The FBWMA is currently owned and managed by the Utah Division of Wildlife
Resources. The NWOD is currently managed by both Salt Lake County and Salt Lake City. The
water level in Farmington Bay has receded over the last decade exposing more upland and drain
as compared to 1999 when EPA conducted its initial studies regarding the northern extent of the
NWOD. The exposed canal as well as the mouth, where the NWOD discharges into Farmington
Bay, is clearly discernible and samples were collected from key locations where contamination
was suspected.
2.0 Nature and Extent of Contamination
3
This section presents the distribution of COPCs identified in the 2011 site investigation for the 0-
6” and 12-18” depth intervals. No data were collected for the 6-12” interval. Additional samples
were collected from depths of 12-18” at stations FBWMA-17-11, FBWMA-010-11, FBWMA-
007-11, and FBWMA-005-11. Note that these location designations have been truncated from
those outlined in the SAP. Instead of using the full numeric year at the end of each location
designation, only the last two digits were used.
Comparisons were made to co-located sampling locations previously studied by CDM and
USFWS. Two locations were selected as reference sites, FBWMA-024-11 and FBWMA-025-
11, based on their distance from the impacted area as well as a review of historical
documentation indicating that areas further north of the FBWMA had lower COPC levels.
Results from the 2011 site investigation are shown in Tables 1 through 3. Historical comparison
data from the previous studies conducted by CDM and the USFWS are shown in Table 4. A
map depicting the 2011 sampling locations is included in Figure 1.
2.1 Lead
Results from the 2011 site investigation 0-6” depth interval showed that lead concentrations
ranged from 28 mg/kg at sampling location FBWMA-021-11 to 325 mg/kg at sampling location
FBWMA-019-011 (Table 1). The highest concentrations of lead were noted near the mouth of
the canal at sampling locations FBWMA-018-11, FBWMA-019-11, and FBWMA-020-11. Lead
concentrations at these sites were 234 mg/kg, 325 mg/kg, and 291 mg/kg, respectively. These
locations are approximately 2061 feet to 2615 feet from die mouth of the canal (approximate
sampling location FBWMA-021-11). As distance increases from the mouth of the canal outward
past the three sampling locations mentioned above, lead concentrations decrease. Most notable
decreases in lead concentrations were to the west of the mouth of the canal at sampling locations
FBWMA-001-11, FBWMA-002-11, and FBWMA-023-11, where concentrations were typically
less than 100 mg/kg. For samples collected at 12-18”, lead concentrations ranged from 8.9
mg/kg to 34.7 mg/kg. Results for the 0-6” and 12-18” depths are shown in Table 1.
2.2 Mercury
Mercury concentrations in the 0-6” depth interval ranged from 0.077 mg/kg at site FBWMA-
010-1 1 to 5.3 mg/kg at site FBWMA-019-11 (Table 1). As seen in the lead results for sediment,
the highest concentrations of mercury were noted at sampling locations FBWMA-018-11,
FBWMA-019-11, and FBWMA-020-11, with mercury concentrations of 2.7 mg/kg, 5.3 mg/kg,
and 4 mg/kg, respectively. For sites that were sampled at the 12-18” depth interval, mercury
concentrations ranged from 0.077 mg/kg to 0.24 mg/kg. The reference samples at sampling
locations FBWMA-024-11 and FBWMA-025-1 lhad concentrations of0.343 mg/kg and 0.30
mg/kg.
4
2J PAH
Total PAH values for the 0-6” depth interval ranged from 39 ug/kg to 7330 ug/kg (Table 2).
Worth noting are the PAH values at sampling locations FBWMA-018-11, FBWMA-019-11,
FBWMA-020-11, and FBWMA-022-11 which have total PAH values far exceeding those
measured at the other sampling locations during the 2011 site investigation. For the 12-18”
depth interval, the total PAH values ranged from 62.4 ug/kg to 116.7 ug/kg. The reference
sampling locations FBWMA-024-11 and FBWMA-025-11 had total PAH values of 79.1 ug/kg
and 86.7 ug/kg, respectively, and were sampled at the 0-6” depth interval. For each non-detected
individual PAH compound, a value of Vz the detection limit was used in the total PAH
calculation.
2.4 TPH-DRO
TPH-DRO concentrations for the 0-6” and 12-18” depth intervals were above the action level of
100 mg/kg accepted for the NWOD for all sampling locations (Table 3). TPH-DRO
concentrations for the 0-6” depth interval ranged from 124 mg/kg at sampling location FBWMA-
003-11 to 10,900 mg/kg at sampling location FBWMA-020-11. The highest concentrations were
observed at sampling locations FBWMA-018-11, FBWMA-019-11, and FBWMA-020-11, with
concentrations ranging from 5,320 mg/kg to 10,900 mg/kg. For the 12-18” depth interval, TPH-
DRO concentrations ranged from 134 mg/kg to 301 mg/kg. The reference sampling locations
FBWMA-024-11 and FBWMA-025-11 had TPH-DRO concentrations of 798 mg/kg and 376
mg/kg, respectively.
2.5 Oil and Grease
Table 3 shows that O&G were detected at concentrations above the NWOD action level of 300
mg/kg at sampling locations FBWMA-010-11 (628 mg/kg), FBWMA-013-11 (406 mg/kg), and
FBWMA-019-11 (654 mg/kg). O&G were not detected at any other sampling locations during
the 2011 event. Figure 2 shows the locations where O&G were detected.
2.6 Historical Comparisons
Results from historical sampling locations co-located with the 2011 sampling locations were
available for five sites for mercury and lead. Sampling locations from the 2011 site investigation
were compared to USFWS data from 1999 and CDM data from 1998 (Table 4). No comparisons
were made for total PAH, TPH-DRO, or O&G since no historical data were available in the
original dataset. This may have been due to lost or misplaced samples, unreported data, or
because the analysis for these chemicals was not performed. Comparisons were made between
historical sampling location 00ODSE03 and the 2011 sampling location FBWMA-009-11. Even
though the sampling locations do not match up identically, they are believed to be within close
enough proximity to one another to give a useable comparison. Figure 1 shows the sampling
locations from the 2011 sampling events and the co-located sampling locations.

3.0 Evaluation of Hazard Quotients
3.1 Data manipulation
The analytical data for TPH-DRO, O&G, lead, and mercury in the 25 surface and 4 subsurface
sediment samples collected in 201 Iwere used “as is” in the evaluation, even though all of the Pb
values, and four of the Hg values, were flagged as “J” (i.e., estimated). All of the reported
concentrations of Pb, Hg (except for one value), and TPH-DRO were also present above their
analytical detection limits. A mercury concentration was reported as non-detect in one of the four
subsurface sediment samples, but a value of 'A the detection limit was used for data analysis
purposes. Only three of the 25 surface sediment samples and none of die four subsurface
sediment samples had O&G levels above the detection limit. The database used in the
assessment reported the remaining 26 O&G values as “0”, with no level of detection indicated.
Therefore, these values could not be evaluated further.
The total PAH level in each sediment sample was calculated by summing the concentrations for
the following individual PAHs: acenaphthene, acenaphthylene, anthracene, benzo(a)anthracene,
benzo(a)pyrene, benzo(a)fluoranthene, benzo(g,h,i)perylene, benzo(k)fluoranthene, chrysene,
dibenzo(a,h)anthracene, fluoranthene, fluorene, indeno(l,2,3-cd)pyrene, naphthalene,
phenanthrene, and pyrene. All non-detects for PAH analytes were included in the calculations at
one-half of their detection limits.
3.2 Benchmarks
As discussed in Section 1.0 (Introduction), the action levels for TPH-DRO (100 mg/kg) and
O&G (300 mg/kg) proposed by the NWOD Working Group were available for use in die data
analysis presented in the next subsection.
No such values were proposed for lead, mercury, or total PAHs. Instead, the consensus-based
Threshold Effect Concentrations (TECs) developed by MacDonald et al. (2000) were retained
for use in the data analysis. These TECs are as follows: lead = 35.8 mg/kg, mercury = 0.18
mg/kg, and total PAHs = 1,610 fig/kg. They should be considered conservative since TECs
represent concentrations at which no adverse effects to benthic invertebrates are expected.
3 J Data analysis
The analytical data for the sediment samples collected from die FBWMA in September 2011
were interpreted in two different ways, as follows:
• Hazard quotients (HQs)
HQs were calculated for the 25 surface and the four subsurface sediment samples by
dividing each contaminant level by its respective benchmark. Hence,
6
HQ = [contaminant!
benchmark
HQs have no units. A value > 1.0 indicates the potential for unacceptable risk to benthic
invertebrates. A value <1.0 indicates that levels of risk are acceptable.
Correlation analysis
A correlation analysis was performed on the analytical data of the 25 surface sediment
samples to determine if a relationship existed between the concentrations of four of the
five contaminants (note: O&G was excluded because only three detected data points were
available). The following correlations were performed:
o Pb vs. Hg
o Pb vs. TPH-DRO
o Pb vs. total PAHs
o Hg vs. TPH-DRO
o Hg vs. total PAH
o TPH-DRO vs. total PAHs
Six figures (see further below) were prepared to illustrate the results of this analysis.
Each figure also provides the value for r2 and the statistical significance. The r2
represents die coefficient of determination, which indicates the proportion (or percentage)
of the total variation for the variable on the Y-axis which is accounted for by the fitted
model.
4.0 Interpretation
4.1 HQs for surface sediments
Table 5 summarizes the HQs for the 25 surface sediments collected from FBWMA.
Table 8 provides the analytical data used to calculate these HQs. The data can be
summarized as follows:
Lead
7
The HQs exceeded 1.0 in all 25 surface sediment samples, except for sample FBWMA-
021-11.
The HQs for the two reference samples (i.e., FBWMA-024-11 and FBWMA-025-11)
both equaled 2.8 and exceeded many of the Pb HQs for the site samples.
The HQs were noticeably higher in four sediment samples, namely FBWMA-018-11,
FBWMA-019-11, FBWMA-020-11, and FBWMA-022-11.
Mercury
The HQs exceeded 1.0 in all 25 surface sediment samples, except for samples FBWMA-
013-11 and FBWMA-021-11.
The HQs for the two reference samples (i.e., FBWMA-024-11 and FBWMA-025-11)
equaled 1.9 and 1.7, respectively, and were among die lowest measured in the 25 surface
sediment samples.
The HQs were noticeably higher in three sediment samples, namely FBWMA-018-11,
FBWMA-019-11, and FBWMA-020-11.
TPH-DRO
• The HQs exceeded 1.0 in all 25 surface sediment samples.
• The HQs for the two reference samples (i.e., FBWMA-024-11 and FBWMA-025-11)
equaled 8.0 and 3.8, respectively. The reference HQ of 8.0 exceeded many of the DRO
HQs of the site samples.
• The HQs were noticeably higher in four sediment samples, namely FBWMA-018-11,
FBWMA-019-11, FBWMA-020-11, and FBWMA-022-11.
Oil A Grease
Concentrations above the detection limit were available for only three of die 25 surfece
sediment samples, resulting in HQs ranging between 1.4 and 2.2. HQs could not be
derived for either one of the reference samples due to the lack of detection. Not enough
O&G data were available to identify patterns or draw conclusions.
Total PAHs
8
• Sixteen of 23 HQs fell below 1.0. Two samples (FBWMA-15-11 and FBWMA-016-11)
were destroyed during shipping to the analytical laboratory. Therefore no data were
available to develop HQs for those two samples.
• The HQs for the two reference samples (i.e., FBWMA-024-11 and FBWMA-025-11)
were among the lowest measured in the 25 surface sediment samples. They equaled 0.05
and 0.1, respectively.
• The HQs equaled or exceeded 1.0 in sediment samples FBWMA-002-11 (1.0), FBWMA-
018-11 (1.3), FBWMA-019-11 (2.3), FBWMA-020-11 (4.6), and FBWMA-022-11 (1.4).
4.2 HQs for subsurface sediments
Table 6 summarizes the HQs for the four subsurface sediments collected from die FBWMA.
Table 9 provides the analytical data used to calculate the HQs. The HQs for all five
contaminants in all four subsurface sediment samples were lower than die HQs for the same five
contaminants in the surface sediment samples collected at the same locations. When compared
to their surface sample counterparts, subsurface sediment HQs decreased by <2 to 10.
43 Correlations
Figures 3 through 8 show die correlation analyses for the contaminant levels measured in die 25
surface sediment samples collected in 2011. Each figure includes a vertical and horizontal line
to indicate the sediment benchmarks for the two contaminants included in the correlation
analysis. Note that, by definition, all die data points located to the right of the vertical sediment
benchmark line and/or above the horizontal sediment benchmark line have HQs > 1.0. The
results can be summarized as follows:
• A statistically significant relationship was found between the concentrations of Pb and
Hg (r2 = 0.91, p c 0.0001; see Figure 3) and between the concentrations of TPH-DRO
and total PAHs (r2 = 0.89, p < 0.0001; see Figure 8). The r^’s were substantially lower,
but still statistically significant (all p’s < 0.0001), between individual metals and organics
(see Figures 4 to 7). •
• All six figures showed four data points (indicated by an asterisk) with consistently higher
contaminant levels. The highest three concentrations came from samples FBWMA-018-
11, FBWMA-019-11, and FBWMA-020-11. These three samples were collected next to
each other and appear to represent a distinct area of elevated contamination in the
FBWMA, what we will refer to as a “hot spot” from this point forward. The remaining
high concentration was observed at FBWMA-022-11, located at the mouth of the
NWOD. This location may also represent an additional “hot spot”.
9
Table 7 shows that the strength of the relationships presented in Figures 3 through 8 was
largely driven by these four “hot spot” samples. The r2 dropped substantially in all six
correlations when the four “hot spot” data points were removed from the analysis. The
statistical significance was also eliminated in four of the six comparisons. This
observation further strengthened the view that the sediment at and around these four
sampling locations may need further attention.
5.0 Uncertainties
Uncertainties, which are inherent in any evaluation of this nature, need to be identified in order
to provide context to the risk management decision-making process. The major uncertainties are
discussed below.
• The HQs for Pb, Hg, and total PAHs were calculated using the consensus-based TECs
developed by MacDonald et al. (2000). MacDonald et al. (2000) also developed
consensus-based Probable Effects Concentrations (PECs), which represent levels at
which an effect to benthic invertebrates becomes possible. The PECs are as follows: Pb
= 128 mg/kg, Hg = 1.06 mg/kg, and total PAHs = 22,800 pg/kg. A review of the
analytical data presented in Table 8 showed the following patterns:
o The Pb levels in surface sediment just exceeded the PEC for Pb in samples
FBWMA-010-11 (135 mg/kg), FBWMA-012-11 (132 mg/kg), and FBWMA-015-
11 (129 mg/kg). Greater exceedances of the PEC for Pb were observed in
samples FBWMA-018-ll (234 mg/kg), FBWMA-019-11 (325 mg/kg), FBWMA-
020-11 (291 mg/kg), and FBWMA-022-11 (162 mg/kg). It was noteworthy
the Pb levels in the two reference samples (FBWMA-024-11 and FBWMA-025-
11) were both relatively high at 102 mg/kg each.
o The Hg levels in surface sediment exceeded the PEC for Hg only in samples
FBWMA-018-11 (2.7 mg/kg), FBWMA-019-11 (5.3 mg/kg), and FBWMA-020-
11 (4.0 mg/kg).
o The total PAH levels did not exceed the PEC for total PAHs in any of the 25
surface sediment samples. This pattern suggested that total PAHs were unlikely
to be a major risk driver at the FBWMA.
• It was not known if the cleanup goals for TPH-DRO and O&G were originally derived to
protect benthic invertebrates. The HQs implicitly assumed that the cleanup goals were
risk-based, even though this could not be verified.
The Pb and TPH-DRO levels measured in the two reference sediment samples were
higher than over half of the Pb and TPH-DRO levels measured in the samples collected
from the FBWMA area affected by the NWOD. This observation suggested that the
FBWMA may be impacted by other contaminant sources not associated with the NWOD,
or that contamination from the NWOD migrated farther into the bay than expected. The ’
10
presence of relatively high levels of Pb and TPH-DRO in the reference samples
represented an uncertainty that should be considered in the management decision-making
process. For example, the Pb level in the reference samples equaled 102 mg/kg but 132
mg/kg in sample FBWMA-012-11 (see Table 8). The difference between these two
values (132-102 = 30 mg/kg) represents the direct contribution of Pb from the NWOD at
this sampling location. This value fell below the TEC for Pb (35.8 mg/kg), which
suggested no potential for site-related risk, even though the HQ for Pb in FBWMA-012-
11 equaled 3.7 (see Table 5).
No data exist about the bioavailability of the target contaminants to the benthic
invertebrate community at the FBWMA. The bioavailability of divalent metals (which
includes Pb but not Hg) in sediments is a function of Acid Volatile Sulfides (AVS),
Simultaneously Extracted Metals (SEM), and the fraction of organic carbon (/«.) present
in the samples (EPA, 2005). The bioavailability of total PAHs in sediments is a function
of the organic carbon content of the sample (EPA, 2003b). These variables were not
measured in any of the sediment sample collected for the current study. Hence, it was not
possible to quantify the bioavailability (and hence the potential for toxicity) of Pb, Hg,
and total PAHs to the benthic invertebrate community and help determine if the HQs
represented actionable or only hypothetical risk.
This study compared sediment contaminant levels to TECs and generic cleanup goals.
These benchmarks were assumed to protect benthic invertebrates, but did not provide any
information on the potential for risk to waterfowl that may feed in the bay and may come
in direct or indirect contact with the contaminated sediment. Such an evaluation would
need more data related to water depth, the type and abundance of benthic invertebrates or
other food items, the kind of bird species present at the FBWMA, the feeding strategies
of these bird species, and other exposure-related issues, such as contaminant
bioavailability and food chain accumulation. This lack of information represents an
important uncertainty that should be considered in the management decision-making
process.
6.0 Conclusions
In September 2011, Tech Law collected sediment samples at 25 locations from the FBWMA in
the general vicinity of where the NWOD enters in the GSL. Twenty five samples were collected
at the sediment surface (0-6” deep) and four more samples were collected from the subsurface
(12-18” deep). All of the samples were analyzed for metals, TPH-DRO, O&G, and PAHs. Total
PAH was calculated for each sample as the sum of 16 individual PAHs.
The contaminant levels in the surface and subsurface sediment samples were compared against
conservative ecotoxicity-based screening benchmarks (Pb, Hg, and total PAHs) or sediment
cleanup goals (TPH-DRO and O&G) to calculate HQs and assess the potential for unacceptable
risk to benthic invertebrates. A correlation analysis was also used to determine if the levels of
Pb, Hg, TPH-DRO and total PAHs measured in surface sediments were associated to each other.
11
The major findings of the investigation were as follows:
The contaminant levels in the 23 site-related and two reference surface sediment samples
routinely exceeded die ecotoxicity-based screening benchmarks for Pb and Hg (and total
PAHs to a much lesser degree). The level of TPH-DRO in all of the sediment samples,
including the two reference samples, exceeded its cleanup goal.
• FBWMA-018-11, FBWMA-019-11, and FBWMA-020-1 Iwere the three most
contaminated surface sediment samples. They were located in the same general area and
appeared to represent a distinct area of elevated contamination associated with past
releases from the NWOD, which we have termed a “hot spot” for the purposes of this
report. Sample FBWMA-022-11, which was die fourth most impacted sample, was
collected within the canal just north of the previous sections where remedial action was
conducted. The area represented by FBWMA-022-11, as well as the other areas that
were sampled during this investigation, were not included in the previous remedial action
and should be representative of historical deposition from the drain.
High i^’s and statistically significant relationships were found between die concentrations
of Pb and Hg (r2 = 0.91), and between the concentrations of TPH-DRO and total PAH (r2
= 0.87) using the frill 25 surface sediment sample dataset. Weaker but still significant
relationships were found between the metals and the organics in the same dataset.
However, removing the four “hot spot” samples from the analysis eliminated the
statistical significance in four of the six comparisons, which confirmed that the sediment
around the four “hot spot” sampling locations may require special attention in the future.
The contamination measured in the four subsurface (12-18”) sediment samples was
substantially lower than that measured in the four surface (0-6”) sediment samples
collected from the same location. This pattern suggested that the historic contaminants
released by the NWOD may be mostly confined to the “biotic active zone” in die top 6”
of the sediment in the FBWMA.
Not enough data were available to determine if the exceedances of die various benchmarks and
cleanup goals observed in this study represented actionable risk. However, there is enough
information to suggest that sediment in Farmington Bay is potentially impacted by contaminants
from the NWOD. Additional investigation should be performed by the NWOD working group
to determine whether an actionable risk to the environment exists. This may include (but is not
limited to) measuring AVS, SEM, and foe, and sediment toxicity testing. Sediment exposure to
other receptors, such as migratory birds, may need to be evaluated as well. Finally, two points
should be considered during the planning process for future investigation with the
NWOD: 1) the FBMWA may be impacted by other contamination sources not associated with
the NWOD, and 2) contamination from die NWOD may have migrated further into the Bay than
expected.

II. Sample Management
The samples were received at the laboratory above the temperature limits of 4°C ±20C, at 16°C;
however, as the samples had insufficient time to chill, no qualifications were required. The
samples were received intact, on ice, and properly preserved. The chains-of-custody (COCs)
were appropriately signed and dated by field and laboratory personnel. Custody seals were
present and intact upon receipt at the laboratory.
No issues were noted by the laboratory in the case narrative. The reviewer noted Sample Log-
In Sheet reported that sample tags were absent and were not listed on the COC; however, the
reviewer noted the tags were listed on the COC. Additionally, the reviewer noted that no
sample was designated for quality control (QC) analyses. The laboratory chose a sample for
QC analyses.

III. Method Analyses
A. Contract Laboratory Program Statement of Work for Inorganic Superfund
Methods, ISM01.3—Metals
Reviewed By: P. Meeks
Date Reviewed: July 27, 2015
The samples listed in Table 1 for this analysis were validated based on the guidelines outlined in
the Quality Assurance Project Plan for U. S. EPA Region 8 CERCLA Site Assessment (2013),
United States Environmental Protection Agency Contract Laboratory Program Statement of Work
for Inorganic Superfund Methods, ISM01.3 (2005), and the National Functional Guidelines for
Inorganic Superfund Data Review (2010).
• Holding Times: The six-month analytical holding time was met.
• Calibration:
o Initial calibration: Five standards and a blank were analyzed for all analytes. All non­
zero initial calibration results were within +30% of the true values. Linear regression
initial calibration correlation coefficients were >0.995 and the intercepts were less than
the reporting limits. Although required by the method to be below the RL, the lowest
non-zero standards were at the RL. As nondetected data were reported at the RL, no
qualifications were deemed necessary.
o Initial (ICV) and continuing calibration (CCV) verification: ICV and the CCV recoveries
were within 90-110%.
• Blanks: There were detects in the method blank and CCBs, but none were sufficient to
qualify the site samples.
• Interference Check Samples (ICSA/B): The ICSA and ICSAB recoveries for the analytes
were within the 80-120% or ±2* the RL, whichever was greater. No analytes were
detected in the ICSAs at concentrations indicative of matrix interference.
• Laboratory Control Samples (LCS): LCS recoveries were within 70-130%.
• Laboratory Duplicates: A laboratory duplicate analysis was performed on sample
MH0AB0. The antimony results exceeded the control limit of ± the reporting limit (RL) and
the lead (78%) and magnesium (46%) RPDs exceeded the control limit; therefore, results
for these analytes were qualified as estimated, “J,” for detects and, “UJ,” for nondetects in
the samples. The remaining results were within the control limits of RPDs <20% for
results 55* the (RL) and +RL for results <5* the RL
6 Revision 0

DATA VALIDATION REPORT SDG: MH0AA9
• Matrix Spike: A matrix spike analysis was performed on sample MHOABO. Results were
not assessed when the native concentration exceeded the spike amount by 4* or more.
Recoveries for arsenic (136%), manganese (126%), and zinc (134%) were above the
control limit; therefore, detects for these analytes in the samples were qualified as
estimated with a potential high bias, “J+.” The antimony recovery was below the control
limit at 25%; therefore, antimony detected in the samples was qualified as estimated with a
potential low bias, “J-.” As the post digestion spike recovery for antimony was acceptable,
nondetected antimony in sample MH0AB2 was qualified as estimated, “UJ," instead of
being rejected. The remaining recoveries were within 75-125%.
• Post Digestion Spike: A post digestion spike analysis was performed on sample MHOABO
for the analytes with matrix spike recovery outliers. The recoveries were within the control
limits of 75-125%.
• Serial Dilution: A serial dilution analysis was performed on sample MHOABO. Results
were not assessed unless the native concentration was nominally 50x the MDL. The
applicable percent differences (%Ds) were within the control limit of <10%.
• Sample Result Verification: Calculations were verified and the sample results reported on
the sample result summary were verified against the raw data. No transcription errors or
calculation errors were noted. Reported nondetects are valid to the reporting limit;
however, the EDD appeared to report nondetects to the method detection limit.
In order to report the analyte within the linear range of the calibration, calcium was
reported from 2* dilutions in samples MH0AA9, MHOABO, and MH0AB1.
The laboratory electronic data deliverable (EDD) contained two field listing sample results:
LAB_RESULT and FINAL_RESULT. The FINAL_RESULT field reported the sample
result with too many significant digits. The LAB_RESULT field primarily contained the
results reported on the Form Is in the data package, but results requiring rounding were
not rounded.
• Field QC Samples: Field QC samples were evaluated, and if necessary, qualified based
on method blanks and other laboratory QC results affecting the usability of the field QC
data. Any remaining detects were used to evaluate the associated site samples.
Following are findings associated with field QC samples:
o Field Blanks and Equipment Rinsates: No field blank or equipment rinsate
samples were identified in this SDG.
o Field Duplicates: There were no field duplicate samples identified in this SDG.

III. Method Analyses
A. Contract Laboratory Program Statement of Work for Inorganic Superfund
Methods, ISM01.3—Metals
Reviewed By: P. Meeks
Date Reviewed: July 27, 2015
The samples listed in Table 1 for this analysis were validated based on the guidelines outlined in
the Quality Assurance Project Plan for U. S. EPA Region 8 CERCLA Site Assessment (2013),
United States Environmental Protection Agency Contract Laboratory Program Statement of Work
for Inorganic Superfund Methods, ISM01.3 (2005), and the National Functional Guidelines for
Inorganic Superfund Data Review (2010).
• Holding Times: The six-month analytical holding time was met.
• Tuning: The mass calibration and resolution check criteria were met. Tuning solution
%RSDs affecting sample results were <5% and masses of interest were calibrated to < 0.1
atomic mass unit (amu).
• Calibration:
o Initial calibration: Five standards and a blank were analyzed for all analytes. All non­
zero initial calibration results were within ±30% of the true values. Linear regression
initial calibration correlation coefficients were >0.995 and the intercepts were less than
the reporting limits. Although required by the method to be below the RL, the lowest
non-zero standards were at the RL. As nondetected data were reported at the RL, no
qualifications were deemed necessary.
o Initial (ICV) and continuing calibration (CCV) verification: ICV and the CCV recoveries
were within 90-110%.
• Blanks: Results listed in the table below were qualified as nondetected, “U,” at the
reporting limits. There were other detects in the method blank and CCBs, but none were
sufficient to qualify the site samples.

• Interference Check Samples (ICSA/B): The ICSA and ICSAB recoveries for the analytes
were within the 80-120% or ±2* the RL, whichever was greater. No analytes were
detected in the ICSAs at concentrations indicative of matrix interference.
• Laboratory Control Samples (LCS): LCS recoveries were within 70-130%.
• Laboratory Duplicates: A laboratory duplicate analysis was performed on sample
MH0AA2. The results were within the control limits of RRDs <20% for results >5* the RL
and ±RL for results <5* the RL
• Matrix Spike: A matrix spike analysis was performed on sample MH0AA2. The
interferents, which are not required in the spike mix, were not spiked. The recoveries were
within 75-125%.
• Post Digestion Spike: No post digestion spike analyses were performed on a sample from
this SDG.
• Serial Dilution: A serial dilution analysis was performed on sample MH0AA2. Results
were not assessed unless the native concentration was nominally 50x the MDL. The %D
for arsenic exceeded the control limit at 11%; therefore, arsenic in the samples, all detects,
was qualified as estimated, “J.” The remaining percent differences (%Ds) were within the
control limit of <10%.
• Internal Standards Performance: All sample internal standard intensities were within the
control limits of 60-125% of the calibration blank.
• Sample Result Verification: Calculations were verified and the sample results reported on
the sample result summary were verified against the raw data. No transcription errors or
calculation errors were noted. Reported nondetects are valid to the reporting limit;
however, the EDD appeared to report nondetects to the method detection limit.
In order to report the analyte within the linear range of the calibration, calcium in samples
MH0AA5 and MH0AA6 was reported from 2* dilutions and sodium in all samples was
reported from 5* dilutions.

The laboratory electronic data deliverable (EDD) contained two field listing sample results:
LAB_RESULT and FINAL_RESULT. The FINAL_RESULT field reported the sample
result with too many significant digits. The LAB_RESULT field primarily contained the
results reported on the Form Is in the data package, but results requiring rounding were
not rounded.
• Field QC Samples: Field QC samples were evaluated, and if necessary, qualified based
on method blanks and other laboratory QC results affecting the usability of the field QC
data. Any remaining detects were used to evaluate the associated site samples.
Following are findings associated with field QC samples:
o Field Blanks and Equipment Rinsates: No field blank or equipment rinsate
samples were identified in this SDG.
o Field Duplicates: Samples MH0AA5 and MH0AA6 were identified as field
duplicate samples. All detects were in common and the RPDs for analytes
detected above the reporting limit were less than 30%.

Dear Ms Williams:
Enclosed for your review is the Site Reassessment (SRA) Report for the Redwood Road
Dump site (referred to as the "Site"). The Site was the primary landfill for Salt Lake City from 1923
until 1962. The Site is estimated to contain approximately 1,340,000 cubic yards of refuse and fill.
Interstate 215 was constructed through the center of the Site in 1988 creating an eastem and westem
refuse pile.
The northem portion of the westem landfill is used for the City's automobile impound lot. Salt
and gravel are stored on the southem portion of the westem landfill. A City vehicle washing and
refueling facility is under construction on City property northwest of the eastem landfill. Snow
cleared from downtown Salt Lake City in the winter is placed on the highest portion of the eastem
landfill by City streets personnel, potentially increasing the volume of contaminated landfill leachate.
A 1991 Site Investigation and a 2000 Targeted Brownfields Assessment have established the
following:
Elevated concentrations of lead (2,610 mg/kg), benzo (a) pyrene (5,000 /ig/kg) and dibenz (a, h)
anthracene (1,000 /xg/kg) were identified in subsurface soils. Elevated concentrations of arsenic.
(1,290 ng/L) antimony (34.2 /ig/L), selenium (14.8 /ig/L) and pentachlorophenol (3 /ig/L) have
been found in Site groundwater. The sampling of downgradient wells was not included in the
previous studies. Therefore, the extent of downgradient groundwater contamination is unknown.
City Drain Canal surface water lead concentrations rise from a non-detectable background
concentration to a high of 59.2 /ig/L downstream from the Site. This concentration significandy
exceeds the surface water Criteria Continuous Concentration of 2.5 /ig/L. Arsenic levels increase
from a background concentration of 61 /ig/L to 82.8 /ig/L after surface water passes the Site. A
wetland environment exists ten miles downstream of the Site at the Great Salt Lake.
Approximately 50 miles of wetland frontage occur within the 15 mile target distance Hmit.
Several duck hundng clubs are located within these wedand areas. Site.drainage enters the Great
Salt Lake at Farmington Bay Wildlife Refuge.

We recommend that an Expanded Site Invesdgation include; (1) the sampling of downgradient
shallow wells and wedands and, (2) the resampling of groundwater and surface water. Inorganic and
organic sampling data can then be evaluated with previously collected results to better understand
threats to wedands and wildlife and the potential for site listing on the Nadonal Priorides List.
After reviewing the SRA report, please inform us of any comments or changes that need to be
incorporated in the final version of the document. Please contact Neil Taylor at [phone] if you

1.0 INTRODUCTION
Under authority of the Comprehensive Environmental Response, Compensafion, and
Liability Act (CERCLA), as amended by the Superfund Amendments and
Reauthorizadon Act (SARA), and in accordance with applicable provisions of the
Nadonal Confingency Plan, the Utah Department of Environmental Quality, Division of
Environmental Response and Remediation (DERR) has prepared this Site Reassessment
Report (SRA) for the Redwood Road Dump, UTD980961502 (referred to as the "Site")
in Salt Lake City, Salt Lake County, Utah. This SRA was prepared under a cooperadve
agreement between DERR and the U.S. Environmental Protecdon Agency, Region 8
(EPA). The purpose of the Site details described herein is to report informafion
conceming current Site conditions, assess the threat posed to human health and the
environment from hazardous materials or potendal releases of hazardous materials and to
support decisions regarding further invesdgadon under CERCLA or other appropriate
authority. Addidonally, contaminant pathways/targets and near future uses of the Site
were examined to identify if any possible changes to the property were imminent. The
Site Visit Report is included as Appendix A. The EPA Preliminary Assessment
Worksheet is provided as Appendix B.
2.0 SITE OBJECTIVES
The objecdves of the acdvides performed during the SRA were related to assessing if
hazardous substances located on-site pose a threat to human health or the environment.
The objectives of this SRA were to:
Determine the condnued presence of contamination in selected media;
Assess the potendal contaminadon characterisdcs;
Assess the potendal routes for contaminant migradon;
Assess the suspected exposure pathways;
Idendfy potendal targets that may be affected by on-site contaminadon as
well as other targets that may be impacted by the migradon of the
contamination via the suspected exposure pathways; and
• Determine if condnued assessment under CERCLA is warranted.
3.0 SITE LOCATION DESCRIPTION
3:1 SITE HISTORY AND PREVIOUS WORK
The Site extends west from 1900 West Street to 2200 West Street, and south from 500
South Street to Indiana Avenue (800 South) in Salt Lake City, Utah (Figure 1). The Site
is approximately 70 acres in size and is owned by Salt Lake City Corporation (DERR,
1995). The Site is located in the SE 1/4 of the SE 1/4 of the NE 1/4 of Section 9,
Township 1 South, Range 1 West, Salt Lake Base Meridian (USGS, 1962). The Site is
bisected by Interstate 215 (1-215) and includes an eastem and westem refuse pile. The
Salt Lake City Road Maintenance and Automobile Impound Lot is located directly north
(across 500 South Street) of the westem portion of the Site.
The Site was the primary landfill for Salt Lake City from 1923 to 1962, when it was
closed to public dumping (DERR, 1995). The Site is estimated to contain approximately
1,340,000 cubic yards of refuse and fill (DERR, 1995). A manifest system was not in
place at the landfill during its operation and no records remain of waste content or
quantities dumped at the Site (UBSHW, 1987). In addition, no regulations were in place
to limit possible hazardous waste additions to the landfill. The Site was reported to take
in household, commercial and industrial wastes. The Site has experienced numerous sub-
surface fires, occasional bad odors, caving and differential settling due to decomposing
refuse (UBSHW, 1987).
The eastem portion of the Site was used from 1962 to 1995 by Salt Lake City
Corporation's Parks and Recreation Department and Public Services Department for the
disposal of leaves, grass clippings, tree trimmings and storm sewer sludge (DERR, 1995).
1-215 was constructed through the center of the Site in 1988 creating an eastem and .
westem refuse pile. It is believed that waste characteristics at the Site include municipal
wastes such as household, commercial, industrial and organic materials.
A report entitled "Preliminary Investigations Disposition of Garbage Materials in
Abandoned Landfill" (PI) was prepared for the Utah Department of Transportation
(UDOT), Salt Lake City, Utah, by Dr. David W. Eckhoff in July of 1977 (Eckoff, 1977).
The investigation found that mixed garbage and refuse had been dumped and burned on
the Site. Twenty auger holes were drilled into the landfill. Forty three measurements for
explosive gas were taken at five foot intervals within the drill holes. The borehole
explosive gas concentrations are provided in Appendix C, Table 1.
The refuse and cover material in the interstate right-of-way was moved to the east pile
during the construction of 1-215 in 1988 (DERR, 1995). A Preliminary Assessment (PA)
of the Site was prepared by the Utah Department of Health's Bureau of Solid and
Hazardous Waste in 1987. A 1991 Site Inspection (SI) sampling event included seven
groundwater samples, three surface water samples, ten soil samples and three sediment
samples (DERR, 1992). The monitoring well physical groundwater parameters are
provided in Appendix C, Table 2. The organic data results for groundwater and surface
water samples are provided in Appendix C, Table 3. The inorganic analyses for
groundwater and surface water samples are provided in Appendix C, Table 4. The
organic analyses for soil and sediment samples are provided in Appendix C, Table 5.
The inorganic analyses for soil and sediment samples are provided in Appendix C, Table
6. The original report sample location map is provided as Appendix C, Figure 5. Figure
5a places the approximate sample locations on a 2008 satellite photograph. Figure 5b
provides arsenic concentrations for soil and groundwater samples. The original report
Site groundwater map is provided as Figure 6.
EPA Region 8 gave the Site a higher priority for further investigation under CERCLA on
January 27, 1992 (USEPA, 1992). DERR conducted a Site Inspection Prioritization
(SIP) for the Site in September, 1995. The report concluded that the Site may present
hazards to those working and living near it, as well as to transients and bottle collectors
(DERR, 1995). Although the Site is vegetated and surface runoff is slow, the SIP
concluded that the accumulated refuse, soil, and shallow groundwater contain hazardous
substances and these present a threat to human health and the environment.
Chromium and lead contaminated soils were illegally placed on the central part of the
eastem landfill some time during December of 1991 by Tool Design Engineering and
Manufacturing facility personnel (DSHW, 2010). Chromium concentrations in samples
collected from the soil ranged from 1,240 mg/kg to 3,300 mg/kg. Lead concentrations
ranged from 1,000 mg/kg to 1,800 mg/kg. The contaminated soils were discovered in
1992.. Approximately 310 cubic yards of soil was removed from the landfill under the
supervision of the Division of Solid and Hazardous Waste and Terracon Consultants in
November 1997. All eight cleanup verification samples were non-detect for chromium.
Seven of eight confirmation samples were non-detect for lead with the remaining sample
yielding 0.1 mg/kg lead (Terracon, 1997). The EPA residential screening level for lead is
generally 400 mg/kg.
DERR conducted a Targeted Brownsfields Assessment (TBA) for the westem portion of
the Site and the Salt Lake City Road Maintenance and Automobile Impound Lot in June,
2000. Selected figures from that assessment together with 2008 satellite photo overlays
are provided as Appendix D. Field work was conducted to assist Salt Lake City
Corporation in gathering additional information about the Site (DERR, 2001). Appendix
D, Figure 1 identifies the approximate location of trenches cut and sample locations.
Phase I consisted of using a backhoe to cut trenches into the subsuiface to evaluate the
extent and type of refuse present. Soil samples were collected from selected locations.
Phase II consisted of installing 15 direct push borings across the westem landfill. Soil,
soil gas, groundwater and surface water samples were collected and submitted for
laboratory analysis of volatile organics, semivolatile organics, metals and pesticides.
Field observations from the June 15, 2000 trenching and investigation activities suggest
the extent of refuse in the westem landfill is potentially limited to the landfill's eastem
bench.
The Portland Cement Superfund site is located directly south of the eastem landfill and
Indiana Avenue on approximately 71 acres. The risks posed by the Portland cement site
were derived from cement kiln dust and chromium bearing bricks which were landfilled
within the Site boundaries. The dust contained several heavy metals including: arsenic,
cadmium, chromium, lead, manganese and molybdenum. The contaminated soil, kiln
dust and chromium bricks were removed from the Portland cement site from 1992
through 1997. The Portland Cement site Record of Decision for Operable Unit Three
(groundwater) states that groundwater contamination is contained in the shallowest
aquifer within the Portland Cement site boundaries by a canal on the eastem boundary of
the Portland Cement site known as the "City Drain", a City sewer line on the east and
north of the site, and a storm water ditch west of 1-215. Analytical results of semiannual
groundwater monitoring beneath the Portland Cement site indicate that the contaminant
plume is limited to shallow groundwater within the Portland Cement site boundaries
(DERR, 2007).
3.2 CURRENT SITE CONDITIONS AND NEAR FUTURE USES
The northem portion of the westem landfill and the sliver of land directly north of the
westem landfill across 500 South Street are used for Salt Lake City's automobile
impound lot. Salt and gravel are stored on the southem portion of the westem landfill.
Both landfills are perimeter fenced (DERR, 2010a). The landfills are closed to the public
with no dumping allowed (Pope, 2010). The eastem landfill is elevated about 10 feet
above the natural ground surface and is covered with soil and natural vegetation. The
landfill is about 300 yards wide and 400 yards long. Various materials are stored on a
flat area northeast of the eastem landfill. Some of these materials include soil from the
City cemetery, wooden posts, large flowerpots for decorative downtown projects, and
large utility poles.
A City vehicle washing and refueling facility is under construction on City property
northwest of the eastem landfill. The City chips trees, limbs and leaves on a large
asphalted area southeast of the eastem landfill. This material is later hauled to the county
landfill for composting. Plans are being considered to extend this asphalted area further
north and convert the area into a temporary model airplane airport. Access to the landfill
outside the asphalted area will remain restricted (Pope, 2010).
Snow cleared from downtown Salt Lake City is placed on the highest portion of the
eastem landfill by City streets personnel. An area on the elevated eastem landfill has
been leveled and covered with clay and gravel for this purpose.
3.3 GEOLOGY, HYDROGEOLOGY, HYDROLOGY AND METEOROLOGY
The Site is located within the Jordan River Valley of the Great Basin Section of the Basin
and Range Physiographic Province. The Jordan River Valley is bounded by the Wasatch
Mountains to the east, the Oquirrh Mountains to the west, the Traverse Mountain Range ,
to the south, and the Great Salt Lake to the north. Basin-fill deposits were eroded from
the Wasatch and Oquirrh Mountains and deposited in the Salt Lake Valley. The general
stratigraphy of the area is characterized by several hundred to several thousand feet of
unconsolidated and semi-consolidated basin fill deposits. Mountain streams and
historical lakes carried most of the sediment into the basin and ancient Lake Bonneville.
The fine-grained sediments were deposited in deeper portions of Lake Bonneville. The
coarser-grained sediments were deposited along the margins of ancient Lake Bonneville
near the mountains as its level eventually receded to its present level as the Great Salt
Lake (Waddell, et al, 1987).
Precipitation that falls as rain or snow in the mountain ranges flows down the range
fronts and recharges the deep aquifer within the Salt Lake Valley. The shallow water
table aquifer is geiierally recharged by downward infiltration from precipitation, canals,
irrigated lands and streams as well as by upward leakage from the underlying confined
aquifer (Waddell, et al, 1987). Surficial basin fill deposits within the Salt Lake Valley
generally consist of a series of Quaternary lacustrine, alluvial fan, sand dune, mud-rock
flow, ash falls, glacial and flood plain sediments. Groundwater occurs within these
valley fill deposits as a complex series of aquifers (Waddell, et al, 1987). The deeper
aquifer lies in Quaternary deposits of clay, silt, sand, and gravels that are hydraulically
interconnected with individual beds of sand and gravel ranging in thickness from less
than one foot to tens of feet. The maximum thickness of the principal aquifer is greater
than 1,000 feet in the northem portion of the valley. Most deep wells in the Salt Lake
Valley are completed in sediments at depths of less than 1,200 feet.
Municipal wells within four miles of the Site are completed at depths of 1,100 feet and
less (DERR, 1992). There are no wells currently in use on-site (DERR, 2010a). Drilling
logs from the four monitoring wells installed at the Site in 1991, in addition to the well
logs from the neighboring Portland Cement site (UTD980718670) reveal a lithology of
clay, silt and sand beneath the landfill (DERR, 1995). A soil survey of the Salt Lake area
identified the soils at the Site as dumps (Du), Salt Air Siity Clay Loam (Sa), Loamy
Borrow Pits (Lo), Sandy Terrace Escarpments (Sc), and Decker Fine Sandy Loam (De)
(DERR, 1992).
Groundwater flow in the shallow aquifer although complex, due to the interaction with
local surface water and underground utility pathways, is generally to the northwest.
Appendix C, Figure 6 provides known groundwater contours and the anticipated
groundwater flow direction. A 42 inch sanitary sewer is buried at an average depth of 17
feet below grade on the eastem border of the Site. The bedding material of the sewer line
appears to be removing groundwater from the shallow aquifer and routing it to the City
Drain. Groundwater flow under the eastem landfill also appears to be toward the City
Drain (DERR, 1992).
The Salt Lake Valley is located in the Great Basin drainage system, which is a closed
system with no outlets. The Jordan River and its tributaries form the main drainage for
the valley. The Jordan River is a Class 3C stream and discharges into the Great Salt
Lake. The Surplus Canal and the City Drain are located in close proximity to the Site.
The City Drain is located west of 1-215 and just east of the westem landfill. The surplus
Canal is a losing stream and likely receives no contribution from contaminated
groundwater (EPA, 1998). The "North Ditch" drains the City property northeast of the ;
eastem landfill. The ditch is piped to a storm drain that flows to the City Drain. The
City Drain is the primary groundwater discharge point. The City Drain joins the Sewer
Canal approximately six miles to the north of the site. The Sewer Canal eventually
discharges into the Great Salt Lake. The Surplus Canal is located approximately 1,000
feet to the west of the Site. The discharge points for the Jordan River, the Surplus Canal
and the Sewer Canal into the Great Salt Lake are characterized by freshwater marshes.
The discharge points are within the confines of the Farmington Bay Waterfowl
Management Area (DERR, 1992).
The Salt Lake Valley is characterized as being semiarid. The normal maximum
temperature ranges from 37.0° F. in January to 93.7° F in July. The normal minimum
temperature ranges from 19.7° F in January to 61.8° F in July. The average annual
rainfall is 15.31 inches per year with a normal monthly high of 2.21 inches in April and a
normal monthly low of 0.72 inches in July. The average annual snowfall is 58.0 inches.
The estimated pan evaporation is a 3.91 inches per year. The winds are predominantly
from the south and southeast and have a mean speed of four to five miles per hour
(Ashcroft, 1992).
3.4 SITE CONCEPTUAL MODEL
Water from precipitation and snow dumping flow through the unlined landfill waste. The
leachate contaminates shallow groundwater. The contaminated groundwater flows to the
City Drain Canal which bisects the site and is carried north by surface water flow into
wetlands and bird habitats. Contaminated groundwater also flows to the northwest in the
subsurface, potentially contaminating shallow, private water wells. The site conceptual
model is illustrated as a flow chart in Figure 3.
4.0 PATHWAY ANALYSIS
4.1 SITE WASTE SOURCES QUANTITY AND CHARACTERISTICS
Both west and east landfills contain municipal trash and unknown quantities of hazardous
materials. Both petroleum and chemical wastes were found in soil borings that were part
of a 1977 UDOT landfill waste investigation. The volume of the landfills is calculated at
approximately 1,338,000 cubic yards (Eckoff, 1977). The landfills are not properly
contained to minimize leaching of materials into the shallow groundwater.
4.2 GROUNDWATER MIGRATION PATHWAY
4.2.1 TARGETS
Seventeen municipal wells from three cities are located within the four mile target
distance range. All wells are located east or south of the Site and hydraulically
upgradient (DDW, 2010a; DDW, 2010b). All three city water systems are blended with
multiple groundwater and surface water sources. Table 1 identifies the population served
by the three public water systems having wells located within four miles of the Site.
Table 1
Population Receiving Groundwater from Wells Located
within Four Miles of the Site
System Name Population Served
Granger-Hunter Improvement District 106,000
Salt Lake City 387,506
South Salt Lake 18,000
Total Population Served 511,506
Approximately 4,102 underground points of diversion are located within four miles ofthe
Site. The uses for the large majority are for "domestic" or irrigation purposes and most
are upgradient of the Site (DWR, 2010). The closest downgradient well is approximately
400 yards northwest of the Site, north of 500 South and east of the Surplus Canal. The
well is 2 inches in diameter, 280 feet deep and was drilled in 1947. All downgradient
wells within 1.5 miles are from 200 to 400 feet deep, artesian wells, drawing from the
deeper, confined aquifer. It is likely that shallow groundwater flows into the City Drain
Canal that bisects the site.
4.2.2 SUMMARY OF PAST RESULTS
4.2.2.1 DERR 1991 Site Inspection
Four monitoring wells installed by EPA and two Portland Cement CERCLA Site
monitoring wells to the south of the Site were sampled (Appendix C, Figure 5). A
duplicate sample was also collected from RD-MW-02.
Appendix C, Tables 3 and 4 summarize the analytical results for the seven groundwater
samples. All samples were analyzed for volatiles, base-neutral/acid extractables,
pesticides, PCBs and metals. There were no pesticide or volatile compounds detected in
the groundwater samples. There were no organic chemical concentrations found above
Superfund Chemical Data Matrix (SCDM) benchmarks (SCDM, 2004). Appendix C,
Table 4 lists the inorganic analyses. A summary of the metals detected near or above
SCDM benchmarks is provided in the table below. Arsenic was detected at 314 /ig/L,
248 /ig/L and 179 /ig/L in three of the four downgradient wells compared to 19 /ig/L in
the background well.. Sample RD-MW-05 contained 34.2 /ig/L antimony. Selenium was
detected in RD-MW-01 at 14.8 /ig/L.

4.2.2.2 DERR 2000 Targeted Brownfields Assessment
Approximately 15 direct push borings were installed across the Site during the 2000
TBA. Soil, soil gas, groundwater and surface water samples were collected and
submitted for volatile organic, semivolatile organic, pesticides, PCBs and dissolved
metals analysis.
Sampling results from the June 2000 TBA revealed pentachlorophenol in sample RRD-
11 at an estimated concentration of 3 /ig/L. The MCL for this compound is 1 /ig/L. No .
other organics were detected in the groundwater above SCDM benchmarks (DERR,
2001).
Arsenic was detected in many groundwater samples above the MCL of 10 /ig/L. Arsenic
was found in sample RRD-1 at 1,290 /ig/L and in RRD- 2 at 1,000 /ig/L. Both sample
locations are north of the Site (Appendix D, Figure 5). Dissolved arsenic was reported in
RRD-7 at an estimated concentration of 1,170 /tg/L. Other groundwater samples ranged
from 2.4 /ig/L to 236 /xg/L. No other dissolved metals were detected in the groundwater
above SCDM benchmarks. The sampling locations and groundwater arsenic
concentrations from the June 2000 sampling event are included as Appendix D, Figure 5.
4.2.3 DATA GAPS
No shallow groundwater samples have been collected farther downgradient (northwest)
ofthe Site than the City impound lot north of 500 South. The closest downgradient well,
located approximately 400 yards northwest of the Site, has not been sampled. No
groundwater sampling has been conducted since June 2000. The present extent of
downgradient arsenic groundwater contamination is therefore unknown.
4.3 SOIL EXPOSURE PATHWAY.
4.3.1 TARGETS
The Redwood Road Dump is enclosed by chain link and barbed wire fences. This barrier
prevents unauthorized vehicle access (DERR, 2010a). There is no on-site population or
residences. There are no schools or day cares located within 200 feet of the site.
4.3.2 SUMMARY OF PAST RESULTS
4.3.2.1 UDOT 1977 Prehminary Inspection
One rotary hole and 19 auger holes were drilled into the landfill from April to May 1977.
Forty three refuse (soil) samples were analyzed for total solids, volatile solids, BOD, and
moisture content. Explosive gas concentrations were measured for a few holes in April
1977 and measured twice in May 1977 for all holes at various depths. Borehole
explosive gas concentrations ranged from zero to 27 percent by volume (Eckoff, 1977).
Explosive gas concentrations are provided as Appendix C, Table 1.
Several locations repeatedly yielded methane concentrations above the lower explosive
limit (LEL). Two of the sampling locations showed methane concentrations above 10
percent by volume. In 12 of the 20 borings, petroleum products were found at or near the
water table. One of the drill holes, G-3C, cited the presence of a "chemical waste" at a
depth of 8-10 feet. Thickness of the refuse in the landfill was determined to vary
between one foot and 29 feet, with the refuse-natural ground interface undulating
between elevations of 4216-4224 feet above sea level.
4.3.2.2 DERR 1991 Site Inspection
Ten soil samples were collected numbering RD-SO-01 through RD-SO-10. Sample
locations are shown in Appendix C, Figure 5 and 5a. Eight of the ten were surface
samples. Sample RD-SO-02 is the background sample. Samples RD-SO-06 and RD-SO-
07 can be considered source samples of "oily waste" taken near the water table from
monitoring wells MW- 2 and MW-4. It does not appear that these two samples were
submitted for inorganic analysis. Sample results can be found in Appendix C, Tables 5-
6.
Appendix C, Tables 5 and 6 sunmfiarize the analytical data results for soil and sediment
samples. Site soils contain above background concentrations of 21 BNA compounds,
five VOA compounds, 12 pesticide compounds, and one PCB compound. None are
above SCDM benchmarks. The PCB compound, aroclor-1260, was detected in RD-SO-
09 at 150 ppb. Table 6 indicates a release of at least 10 metals to the soil has occurred at
the Site. Concentrations of barium, calcium, chromium, copper, iron, lead, mercury,
nickel, sodium, and zinc were detected over three times that of the background sample.
None were above SCDM benchmarks. However, lead has no established SCDM
benchmark. Lead was detected in sample SO-10 at 2,610 mg/kg in the northem comer of
the westem landfill. This sample was taken directly above the refuse inside a hole
previously used to excavate old bottles about three feet below ground surface.
4.3.2.3 DERR 2000 Targeted Brownfields Assessment
Soil samples were collected during installation of the direct push groundwater samples
and from selected trench locations across the Site. Soil samples were collected directly at
the soil/water interface. Most soil samples were collected between seven to nine feet
below ground surface. Soil sample locations are provided as Appendix D, Figure 1 and
provide 2008 satellite imagery for the sample locations.
Lead was reported in sample T-3 at 1,760 mg/kg. Lead was reported in sample SB-2 at an
estimated concentration of 1,930 mg/kg. Poly nuclear aromatic hydrocarbon compounds
were detected from the base of a trench cut (SB-2) along the central portion of the east
bench. Soil samples collected from the base of the 10 foot trench cut revealed benzo (a)
pyrene at 5,000 ug/kg and dibenz (a,h) anthracene at 1,000 ug/kg. The SCDM CRSC for
both compounds is 880 ug/kg. Selected figures from the study are provided in Appendix
D. Figure 4 is the original report sample map identifying the benzo (a) pyrene
concentrations found in soil samples from the westem landfill. Figure 4a is the historic
report sample map detailing the lead concentrations at the westem landfill.
No VOCs, SVOCs or PCBs/Pesticides were detected in any other samples above SCDM
benchmarks or the EPA Region 3 commercial/industrial soil screening criteria. Arsenic
was reported in all soil samples collected from the westem landfill. The highest reported
concentration was 43.9 mg/kg with the remaining concentrations ranging from 6.0 mg/kg
to 25 mg/kg.
4.3.3 DATA GAPS
Only limited subsurface soil hazardous constituent analysis has'been conducted for the
eastem landfill. .
4.4 SURFACE WATER PATHWAY
4.4.1 TARGETS
There are no surface drinking water sources within the 15 mile target distance limit.
Surface waters are not used for fishing within 15 downstream miles. A wetland
environment exists at the Great Salt Lake which is approximately 10 miles downstream
of the Site (Appendix B, Figures on pages 10 and 11). Approximately 50 miles of
wedand frontage occur within the 15 mile target distance limit (USDI, 1990). Several
duck hundng clubs are located within these wetland areas (DWLR, 2010). The Site is
located in a 100 year flood zone (FEMA, 2010).
4.4.2 SUMMARY OF PAST RESULTS
4.4.2.1 DERR 1991 Site Inspection
Three surface water samples were collected at the Site, as well as three sediment samples
(see Appendix C, Figure 5 and 5a). A quality control trip blank water sample was also
taken. Upgradient and downgradient water samples were collected from the City Drain
and a water sample was taken from the unnamed north ditch. The up-gradient City Drain
sample served as the background sample. Sediment samples were taken in the same
general location as the surface water samples.
Surface water sample results tables from this investigation are provided in Appendix C
(Tables 3-6). The SCDM surface water environmental pathway benchmark for acute
exposure is the Criteria Maximum Concentration (CMC) and the benchmark for chronic
exposure is the Criterion Chronic Concentration (CCC). The environmental toxicity of
metals in surface water depends upon water hardness. As the water hardness of the City
Drain has not been determined, the default CMC and CCC values for a water hardness of
100 mg/L is provided. Lead was detected in the north ditch sample at 23.6 /ig/L. The
CMC for lead is 65 /tg/L and the CCC for lead is 2.5 /ig/L. Antimony was detected at 25
/ig/L from RD-SW-02. No CMC or CCC for antimony has been established. Arsenic
was also detected in the upgradient City Drain sample at 53.4 /ig/L and in the
downgradient sample at 59.2 /tg/L (CMC = 340 /ig/L, CCC = 150 /ig/L). .
Appendix C, Table 5 identifies the 11 BNA, six pesticide and two VOA compounds that
were detected in the sediment samples. The majority of these contaminants were
detected in the north ditch, indicating they most probably originated from the landfill.
10
The north ditch sediment sample contained three metal concentrations that were more
than three times the concentration in the upgradient City Drain sediment sample. These
metals include lead (68.2 mg/kg), magnesium (33,000 mg/kg) and zinc (222 mg/kg).
4.4.2.2 DERR 2000 Targeted Brownfields Assessment
Surface water samples RRD-SW-1, RRD-SW-2 and RRD-SW-3 were collected from the
City Drain which borders the westem landfill on the east. RRD-SW-4 was collected
from the northem portion of a possible wedand area identified on the central portion of
the eastem landfill. RRD-SW-5 was a duplicate of RRD-SW-4.
Appendix D, Tables 3, 6, 9 and 12 summarize the surface water analytical results.
Arsenic was reported in the southemmost (background) surface water sample (RRD-SW-
1) at 61 /ig/L, in RRD-SW-2 at 79.7 /ig/L and in RRD-SW-3 at 82.8 /ig/L. All measured
surface water arsenic concentrations were below the CMC (340 /tg/L) and the CCC (150
/ig/L). Lead increased from the background non-detect concentration to 56.1 /ig/L at
RRD-SW-2 and 50.3 /ig/L at RRD-SW-3 (CMC = 65 /ig/L, CCC = 2.5 /ig/L). No other
metals were reported above SCDM benchmarks.
4.4.3 DATA GAPS
Determining the appropriate metal toxicity benchmark requires knowing the average
hardness of City Drain surface water. This value has not yet been determined.
4.5 AIR MIGRATION PATHWAY
4.5.1 TARGETS
There is no on-site population or residences at the Redwood Road Dump. There are no
schools or day cares located within 200 feet of the site. There is a population of 130,095
within the four-mile Target Distance Limit (DERR, 2010b). Table 3 lists the target
population within various distances. Both westem and eastem landfills are fenced. Two
means of access are available to the eastem landfill; one is from the north through a gate
which is locked at night, and one from the south through a road barrier. Approximately
50 miles of wedand frontage occur within the 15 mile target distance limit (USDI, 1990).

4.5.2 SUMMARY OF PAST RESULTS
4.5.2.1 UDOT 1977 Preliminary Inspection
One rotary hole and 19 auger holes were drilled into the landfill from April to May 1977.
Explosive gas concentrations were measured for a few holes in April 1977 and measured
twice in May 1977 for all holes at various depths. Several locations repeatedly yielded
methane concentrations above the lower explosive limit (LEL).
4.5.2.2 DERR 2000 Targeted Brownfields Assessment
Soil gas samples were collected from two locations along the eastem bench of the
westem landfill in accordance with the protocol established in the TBA Workplan and
analyzed for methane. Methane was reported in SG-1 at 23,000 ppmV (46 percent of the
lower explosive limit). Methane was not reported in SG-2 above the level of detection.
4.5.3 DATA GAPS
None identified.
5.0 SUMMARY AND CONCLUSIONS
The Site was the primary landfill for Salt Lake City from 1923 until 1962 and is .
estimated to contain approximately 1,340,000 cubic yards of refuse and fill. The Site was
reported to take in household, commercial and industrial wastes. 1-215 was constmcted
through the center of the Site in 1988 creating an eastem and westem refuse pile. The
refuse and cover material in the interstate right-of-way was moved to the east pile during
the construction. Thickness of the refuse in the landfill varies between one foot and 29
feet, with the refuse-natural ground interface undulafing between elevations of 4216-4224
feet.
Chromium and lead contaminated soils were illegally placed on the central part of the
eastem landfill some time during December of 1991. The contaminated soils were
removed from the landfill in November 1997.
The northem portion of the westem landfill is used for Salt Lake City's automobile
impound lot. Salt and gravel are stored on the southem portion of the westem landfill.
The eastem landfill is elevated about 10 feet above the natural ground surface and is
covered with soil and natural vegetafion. The eastem landfill is about 300 yards wide and
400 yards long. Various materials are being stored on a flat area northeast of the eastem
landfill.
A City vehicle washing and refueling facility is under constmction on City property
northwest of the eastem landfill. Plans are being considered to extend this asphalted area
further north and convert the area into a temporary model airplane airport. Snow cleared
12
from downtown Salt Lake City in the winter is placed on the highest portion of the
eastem landfill by City streets personnel.
The Portland Cement Superfund site is located directly south of the eastem landfill and
south of Indiana Avenue. Semiannual monitoring of the contaminated groundwater
beneath the Portland Cement site indicates that the shallow aquifer contaminant plume
confinues to be contained within the Portland Cement site boundaries.
The 1991 SI and 2000 Targeted Brownfields Assessment have established the following:
• Soil - Concentrations of barium, calcium, chromilim, copper, iron, mercury,
nickel, sodium, and zinc were detected in surface soils over 3 times that ofthe
background sample. In particular, lead was detected in the subsurface soils as
high as 2,610 mg/kg.
Concentrations of benzo (a) pyrene (5,000 /ig/kg) and dibenz (a, h) anthracene
(1,000 /xg/kg) were identified in subsurface soils above SCDM benchmarks. The
SCDM CRSC for both compounds is 880 /xg/kg. There is no on-site population
or residences at the Redwood Road Dump. There are no schools or day cares
located within 200 feet of the site.
• Groundwater - The presence of arsenic (1,290 Mg/L) antimony (34.2 /xg/L),
selenium (14.8 /xg/L), pentachlorophenol (3 Mg/L) have been found in Site
groundwater above SCDM benchmarks. Arsenic contamination above the 10
ng/L groundwater MCL is widespread. However, the closest downgradient
well, located approximately 400 yards northwest of the Site, has not been
sampled. The extent of downgradient groundwater contamination to the
northwest is, therefore, unknown. Seventeen municipal wells from three cities are
located within the four mile target distance limit. All are located east or south of
the Site and hydraulically upgradient. All downgradient wells are privately
owned.
Surface water - The City Drain Canal bisects the site. Water from the canal
eventually enters the Great Salt Lake at Farmington Bay Wildlife Refuge
approximately 10 miles downstream of the site. Approximately 50 miles of
wetland frontage occur within the 15 mile target distance limit (USDI, 1990).
Several duck hunting clubs are located within these wetland areas. There are no
surface drinking water sources within the 15 mile target distance limit of the Site.
Surface waters are not used for fishing within 15 downstream miles.
City Drain Canal surface water lead concentrations rise from a non-detectable
background concentration to a high of 59.2 /xg/L downstream of the Site. This
concentration significantly exceeds the surface water CCC of 2.5 /xg/L. However,
although elevated levels of lead have been detected in subsurface site soils,
elevated levels of lead have not been detected in Site groundwater. Arsenic levels
13
increase from a background concentration of 61 /xg/L to 82.8 /ig/L downstream of
the Site.

SITE VISIT REPORT
SITE VISIT REPORT
For the Redwood Road Dump
CERCLIS ID UTD980961502
On March 9 and 22, 2010 Neil Taylor with the Utah Department of Environmental
Quality, Division of Environmental Response and Remediation conducted a site visit of
properties associated with the investigation of the Redwood Road Dump (Site). This
report describes the Site visits. Supporting photographs can be found at the end of the
visit description. On March 22, Neil Taylor was accompanied by Val Pope, Parks ^
Division Manager with the Salt Lake City Department of Public Services.
The Site is located between 500 South on the North and Indiana Avenue on the South and
from 1900 West on the East to 2200 West on the West. The Redwood Road Dump
consists of westem and eastem covered landfills. Historically the landfills were one unit
but are now bisected by 1-215. Both landfills are covered with soil and vegetated with
native grasses.
We first entered the eastem landfill using an access road located directly behind the Parks
Division building which is located at 1963 West 500 South. Various materials are being
stored on the flat area northeast of the elevated and covered eastem landfill. Some of
these materials include soil from the city cemetery, wooden posts, large flowerpots for
decorative use downtown, and large utility poles.
A city vehicle washing and refueling facility is under construction just northwest of the
eastem landfill. Trees limbs and leaves are chipped up on a large asphalted area
southeast of the eastem landfill. This material is later hauled to the county landfill for
composting. Snow cleared from downtown in the winter is dumped on the highest
portion of the eastem landfill. An area on the elevated eastem landfill has been leveled
and covered with clay and gravel for this purpose.
An open ditch runs north northeast from the Southeastem property drainage to behind the
Parks Division building. The drainage is then piped from the Southwest quarter of the
Parks building to a storm drain on 500 South. The "North Drain" described in previous
site investigation reports, no longer appears to exist.
The narrow, elevated, westem portion of the landfill is located just west of 1-215 and the
City Drain canal and east of a variety of city and private properties mnning down Delong
Street (2105 West). A row of commercial businesses are located on the northem portion
of Delong Street. The city impound lot is located east of these properties. The northem
half of the westem landfill is located east of the city impound lot.
The Salt Lake City Streets Division owns the southem half of Delong Street. This
includes the southem half of the westem landfill. The elevated southem half of the
landfill is being used for storage of a variety of gravel used in street repair and tree limbs.

BACKGROUND/OPERATING HISTORY
6. DESCRIBE OPERATING HISTORY OF SITE: The Site was the primary landfill for Salt Lake
City from 1923 until 1962. The Site is estimated to contain approximately 1,340,000
cubic yards of refuse and fill. The Site was reported to take in household,
commercial and industrial wastes. 1-215 was constructed through the center of the
Site in 1988 creating an eastern and western refuse pile. The refuse and cover
material in the Interstate right-of-way was moved to the east pile during the
construction. Thickness of the refuse in the landfill varies between one foot and 29
feet, with the refuse-natural ground interface undulating between elevations of 4216-
4224 feet.
Source of information: BSHW, 1987; DERR, 1995; Eckoff, 1977
7. DESCRIBE THE NATURE OF SITE OPERATIONS (property size, manufacturing, waste disposal,
storage, etc.): The northern portion of the western landfill is used for the-City's
automobile impound lot. Salt and gravel are stored on the southern portion of the
western landfill. The eastern landfill is elevated about 10 feet above the natural
ground surface and is covered with soil and natural vegetation. The landfill is about
300 yards wide and 400 yards long. Various materials are being stored on a flat area
northeast of the eastern landfill.
Source of information: DERR, 2010a; Terracon, 1997

PA Worksheet
Page 5
8. DESCRIBE ANY EMERGENCY OR REMEDIAL ACTIONS THAT HAVE OCCURRED AT THE SITE: Chromium
and lead contaminated soils were illegally placed on the central part of the eastern
landfill some time during December of 1991. The contaminated soils were removed from
the landfill in November 1997. Several drums were removed on August 10, 1993 that

substance disposal, storage or handling; 2) size/volume/area of all features/
structures that might contain hazardous waste; 3) condition/integrity of each storage
disposal feature or structure; 4) types of hazardous substances handled.
12.BRIEFLY EXPLAIN HOW WASTE QUANTITY WAS ESTIMATED (e.g., historical records or
manifests, permit applications, air photo measurements, etc.): A report entitled
"Preliminary Investigations Disposition of Garbage Materials in Abandoned Landfill"
(PI) was prepared for the Utah Department of Transportation (UDOT), Salt Lake City,
Utah, by Dr. David W. Eckhoff in July of 1977. The investigation found that mixed
garbage and refuse had been dumped and burned on the site. Twenty auger holes were
drilled into the landfill from which the volume and type of waste was calculated.
Source of information: Eckhoff, 1977

14. IS THERE ANY POSITIVE OR CIRCUMSTANTIAL EVIDENCE OF A RELEASE TO GROtJNDWATER?
^ YES • NO
Describe: In 1991, arsenic was detected at 314 ug/'L, 248 /xg/L and 179 ixg/'h in three of
four downgradient wells compared to 19 /xg/L in a background well. Antimony was
detected at 34.2 /xg/L in one well and above background concentrations. In 2000,
arsenic was detected in many groundwater samples above the MCL of 10 /xg/L. Arsenic
was found at 1,2 90 /xg/L and at 1,000 /xg/L in two sample wells located noriih of the
Site. Dissolved arsenic was reported in on the western edge of the western landfill
at an estimated concentration of 1,170 /xg/L. Other groundwater samples ranged from
2.4 /xg/L to 236 /xg/L

18. DISCUSS THE PROBABLE SURFACE RUNOFF PATTERNS FROM THE SITE TO StIRFACE WATERS: The
Surplus Canal and the City Drain are located in close proximity to the site. The
"North Ditch" drains the City property northeast of the eastern landfill. The ditch
is piped to a storm drain that flows to the City Drain. The City Drain is located
west of 1-215 and just east of the western landfill. The City Drain is the primary
groundwater discharge point. The City Drain joins the Sewer Canal approximately six
miles to the north. The Sewer Canal eventually discharges into the Great Salt Lake
approximately 10 miles downstream of the Site. The Surplus Canal is located
approximately 1,000 feet to the west of the Site. The discharge points for the
Jordan River, the Surplus Canal and the Sewer Canal into the Great Salt Lake are
characterized by freshwater marshes. The discharge points are within the confines of
the Farmington Bay Waterfowl Management Area

27. DISCUSS GROUNDWATER USAGE WITHIN FOUR MILES OF THE SITE: Seventeen municipal wells
from three cities are located within the 4-mile target distance range. All are
located east or south of the Site and hydraulically up-gradient. Approximately 4,102
underground points of diversion are located within four miles of the Site. The uses
for the large majority are for "domestic" or irrigation purposes and most are
upgradient of the Site. The closest downgradient well is approximately 400 yards
northwest of the site, north of 500 South and east of the surplus canal. The well is
2 inches in diameter, 280 feet deep and was drilled in 1947.

1.0 INTRODUCTION
Under authority of the Comprehensive Environmental Response, Compensation, and Liability Act
(CERCLA), as amended by the Superfund Amendments and Reauthorization Act (SARA), and in
accordance with applicable provisions of the National Contingency Plan, the Utah Department of
Environmental Quality, Division of Environmental Response and Remediation (DERR) has
prepared this Work Plan as part of an Expanded Site Investigation (ESI) at the Redwood Road
Dump UTD980961502, (referred to as "Site") in Salt Lake City, Salt Lake County, Utah. This ESI
was prepared under a cooperative agreement between DERR and the U.S. Environmental
Protection Agency, Region 8 (EPA). The sampling described in this ESI Work Plan will evaluate
potential sediment and surface water contamination as well as delineate possible exposure
pathways and targets.
2.0 OBJECTIVES
This Work Plan will provide a framework for data collection and sampling activities near the Site
to assess if historical activities caused a release of hazardous substances that pose a potential threat
to human health and the environment. The results from the ESI will be used to evaluate if
significant releases occurred or exist to warrant "listing" the Site on the EPA's National Priorities
List or cleanup of the Site under some other program or authority. Environmental samples will be
collected from off-site locations to determine the presence of contamination from past activities in
the area.
The objectives of this ESI are to:
• Determine the presence of contamination in selected media;
• Assess the potential contamination characteristics;
• Assess the potential routes for contaminant migration;
• Assess the suspected exposure pathways;
• Identify potential targets that may be impacted by the migration of on-site
contamination via the suspected exposure pathways; and
• Determine if continued assessment under CERCLA is warranted.

3.0 BACKGROUND INFORMATION
3.1 SITE LOCATION
The Site extends west from 1900 West Street to 2200 West Street, and south from 500 South Street
to Indiana Avenue (800 South) in Salt Lake City, Utah (Figures 1 and 2). The Site is
approximately 70 acres in size and is owned by Salt Lake City Corporation (DERR, 1995). The
Site is located in the Southeast 1/4 of the Southeast 1/4 of the Northeast 1/4 of Section 9, Township
1 South, Range 1 West, Salt Lake Base Meridian (USGS, 1962). The Site is bisected by Interstate
215 (1-215) and includes an eastern and western refuse pile. The Salt Lake City Road Maintenance
and Automobile Impound Lot is located directly north (across 500 South Street) of the western
portion of the Site.
3.2 SITE HISTORY
The Site was the primary landfill for Salt Lake City from 1923 to 1962, when it was closed to
public dumping. The Site is estimated to contain approximately 1,340,000 cubic yards of refuse
and fill (Eckoff, 1997). A manifest system was not in place at the landfill during its operation and
no records remain of waste content or quantities dumped at the Site (UBSHW, 1987). The eastern
portion of the Site was used from 1962 to 1995 by Salt Lake City Corporation's Parks and
Recreation Department and Public Services Department for the disposal of leaves, grass clippings,
tree trimmings and storm sewer sludge (DERR, 1995). 1-215 was constructed through the center
ofthe Site in 1988 creating an eastern and western refuse pile. It is believed that waste
characteristics at the Site include municipal wastes such as household, commercial, industrial and
organic materials.
The northern portion of the western landfill and the sliver of land directly north of the western
landfill across 500 South Street are used for Salt Lake City's automobile impound lot. Salt and
gravel are stored on the southern portion of the western landfill. Both landfills are perimeter
fenced (DERR, 2010a). The landfills are closed to the public with no dumping allowed. A City
vehicle washing and refueling facility has been constructed on City property northwest of the
eastern landfill. The City chips trees, limbs and leaves on a large asphalted area southeast of the
eastern landfill. Access to the landfill outside the asphalted area will remain restricted (Salt Lake
City Parks, 2010).
The Portland Cement Superfund site is located directly south of the eastern landfill and Indiana
Avenue on approximately 71 acres. Kiln dust from the Portland Cement site contained arsenic,
cadmium, chromium, lead, manganese and molybdenum. Groundwater monitoring beneath the
Expanded Site Investigation Work Plan Utah DEQ/DERR
Redwood Road Dump UTD980961502
Page 2
Portland Cement site indicates that the Portland Cement groundwater contaminant plume is
limited to shallow groundwater that is contained within the Portland Cement site boundaries
(DERR, 2007).
3.3 PREVIOUS INVESTIGATIONS
A Preliminary Assessment (PA) of the Site was prepared by the Utah Department of Health's
Bureau of Solid and Hazardous Waste in 1987. A Site Inspection (SI) was conducted in 1991 and
a Targeted Brownsfields Assessment (TBA) was conducted in June, 2000 for the western portion
of the Site and the Salt Lake City Road Maintenance and Automobile Impound Lot. The 1991 SI
and 2000 Targeted Brownfields Assessment have established the following:
• Soil - Concentrations of barium, calcium, chromium, copper, iron, mercury, nickel,
sodium, and zinc were detected in surface soils over three times that of the background
sample. In particular, lead was detected in the subsurface soils as high as 2,610 mg/kg.
Concentrations of benzo (a) pyrene (5,000 pg/kg) and dibenz (a, h) anthracene (1,000
pg/kg) were identified in subsurface soils above Superfund Chemical Data Matrix
(SCDM) benchmarks (SCDM, 2014). The SCDM Cancer Risk Screening Concentration
(CRSC) for both compounds is 20 pg/kg.
• Groundwater - The presence of arsenic (1,290 pg/L), antimony (34.2 pg/L), selenium
(14.8 pg/L) and pentachlorophenol (3 pg/L) have been found in Site groundwater above
SCDM benchmarks. Arsenic contamination above the 10 pg/L groundwater Maximum
Contaminant Level (MCL) is widespread. However, no public or private drinking water
wells have been identified downgradient of the Site.
• Surface water - The City Drain Canal bisects the Site. Water from the canal eventually
enters the Great Salt Lake at Farmington Bay Wildlife Refuge approximately 10 miles
downstream of the Site. Approximately 50 miles of wetland frontage occur within the
15-mile target distance limit (USDI, 1990).
The SCDM surface water environmental pathway benchmark for acute exposure is the
Criterion Maximum Concentration (CMC) and the benchmark for chronic exposure is the
Criterion Chronic Concentration (CCC). The environmental toxicity of metals in surface
water depends upon water hardness. As the water hardness of the City Drain has not been
determined, the default CMC and CCC values for a total water hardness of 100 mg/L are
provided. City Drain Canal surface water lead concentrations rise from a non-detectable
background concentration to a high of 59.2 pg/L downstream of the Site. This
Expanded Site Investigation Work Plan Utah DEQ/DERR
Redwood Road Dump UTD980961502
Page 3
concentration does not exceed the surface water CMC of 65 pg/L, but significantly exceeds
the surface water CCC of 2.5 pg/L. However, although elevated levels of lead have been
detected in subsurface Site soils, elevated levels of lead have not been detected in Site
groundwater. Arsenic levels in surface water increase from a background concentration of
61 pg/L to 82.8 pg/L downstream ofthe Site. This is below the 340 pg/L CMC and the 150
pg/L CCC (SCDM, 2014; DERR. 2001).
3.4 PHYSICAL CONDITIONS
3.4.1 HYDROGEOLOGY
Precipitation that falls as rain or snow in the mountain ranges flows down the range fronts and
recharges the deep aquifer within the Salt Lake Valley. The shallow water table aquifer is
generally recharged by downward infiltration from precipitation, canals, irrigated lands and
streams as well as by upward leakage from the underlying confined aquifer (Waddell, et al, 1987).
Surficial basin fill deposits within the Salt Lake Valley generally consist of a series of Quaternary
lacustrine, alluvial fan, sand dune, mud-rock flow, ash falls, glacial and flood plain sediments.
Groundwater occurs within these valley fill deposits as a complex series of aquifers (Waddell, et
al, 1987). The deeper aquifer lies in Quaternary deposits of clay, silt, sand, and gravels that are
hydraulically interconnected with individual beds of sand and gravel ranging in thickness from
less than one foot to tens of feet. The maximum thickness of the principal aquifer is greater than
1,000 feet in the northern portion of the valley. Most deep wells in the Salt Lake Valley are
completed in sediments at depths of less than 1,200 feet (Waddell, et al, 1987).
Municipal wells within four miles of the Site are completed at depths of 1,100 feet and less
(DERR, 1992). There are no wells currently in use on-site (DERR, 2010a). Drilling logs from the
four monitoring wells installed at the Site in 1991, in addition to the well logs from the neighboring
Portland Cement site (UTD980718670) reveal a lithology of clay, silt and sand beneath the landfill
(DERR, 1995). A soil survey of the Salt Lake area identified the soils at the Site as dumps (Du),
Salt Air Silty Clay Loam (Sa), Loamy Borrow Pits (Lo), Sandy Terrace Escarpments (Sc), and
Decker Fine Sandy Loam (De) (DERR, 1992).
Groundwater flow in the shallow aquifer although complex, due to the interaction with local
surface water and underground utility pathways, is generally to the northwest. A 42-inch sanitary
sewer is buried at an average depth of 17 feet below grade on the eastern border of the Site. The
bedding material of the sewer line appears to be removing groundwater from the shallow aquifer
and routing it to the City Drain. Groundwater flow under the eastern landfill also appears to be
toward the City Drain (DERR, 1992).

3.4.2 HYDROLOGY
The Salt Lake Valley is located in the Great Basin drainage system, which is a closed system with
no outlets. The Jordan River and its tributaries form the main drainage for the valley. The Jordan
River is a Class 3B stream and discharges into the Great Salt Lake (UAC, 2012). The Surplus
Canal and the City Drain are located in close proximity to the Site. The City Drain is located west
of 1-215 and just east of the western landfill. The Surplus Canal is a losing stream and likely
receives no contribution from contaminated groundwater (USEPA, 1998). The "North Ditch"
described in earlier reports was a depression that drained the City property northeast ofthe eastern
landfill. This depression has been filled in and runoff is now piped to a storm drain that flows to
the City Drain. The City Drain is the primary groundwater discharge point. The City Drain joins
the Sewer Canal approximately six miles to the north of the Site. The Sewer Canal eventually
discharges into the Great Salt Lake. The Surplus Canal is located approximately 1,000 feet to the
west of the Site. The discharge points for the Jordan River, the Surplus Canal and the Sewer Canal
into the Great Salt Lake are characterized by freshwater marshes. The discharge points are within
the confines of the Farmington Bay Waterfowl Management Area (DERR, 1992).
3.4.3 GEOLOGY
The Wasatch Front is underlain by the active Wasatch Fault system. This system is a major
geologic structure that extends generally north and south for a distance of some 210 miles.
Vertical movement along this fault system exceeds three miles. The Wasatch Front is subdivided
into several valleys (Waddell, et al, 1987).
The Site is located within the Jordan River Valley of the Great Basin Section of the Basin and
Range Physiographic Province. The Jordan River Valley is bounded by the Wasatch Mountains to
the east, the Oquirrh Mountains to the west, the Traverse Mountain Range to the south, and the
Great Salt Lake to the north. Basin-fill deposits were eroded from the Wasatch and Oquirrh
Mountains and deposited in the Salt Lake Valley. The general stratigraphy of the area is
characterized by several hundred to several thousand feet of unconsolidated and semi-consolidated
basin fill deposits. Mountain streams and historical lakes carried most of the sediment into the
basin and ancient Lake Bonneville. The fine-grained sediments were deposited in deeper portions
of Lake Bonneville. The coarser-grained sediments were deposited along the margins of ancient
Lake Bonneville near the mountains as its level eventually receded to its present level as the Great
Salt Lake (Waddell, et al, 1987).
Expanded Site Investigation Work Plan Utah DEQ/DERR

3.4.4 METEROLOGY
The Salt Lake Valley is characterized as being semiarid. The normal maximum temperature
ranges from 37.0° F in January to 93.7° F in July. The normal minimum temperature ranges from
19.7° F in January to 61.8° F in July. The average annual rainfall is 15.31 inches per year with a
normal monthly high of 2.21 inches in April and a normal monthly low of 0.72 inches in July. The
average annual snowfall is 58.0 inches. The estimated pan evaporation is a 3.91 inches per year
(USGS, 2009). The winds are predominantly from the south and southeast and have a mean speed
of four to five miles per hour (Ashcroft et al., 1992).
3.5 PRELIMINARY PATHWAY ANALYSIS
Potential exposure pathways and potential data gaps are presented in the Conceptual Site Model
(Figure 3), and are discussed in more detail in the following sections.
3.5.1 WASTE SOURCE CHARACTERIZATION
Both west and east landfills contain municipal trash and unknown quantities of hazardous
materials. Both petroleum and chemical wastes were found in soil borings that were part of a 1977
UDOT landfill waste investigation. The volume of the landfills is calculated at approximately
1,340,000 cubic yards (Eckoff, 1977). The landfills are not properly contained to minimize
leaching of materials into the shallow groundwater.
Chromium and lead contaminated soils were illegally placed on the central part ofthe eastern
landfill some time during December of 1991 by Tool Design Engineering and Manufacturing
facility personnel (DSHW, 2010). Chromium concentrations in samples collected from the soil
ranged from 1,240 mg/kg to 3,300 mg/kg. Lead concentrations ranged from 1,000 mg/kg to 1,800
mg/kg. The contaminated soils were removed in 1997 (Terracon, 1997).
3.5.2 SOIL EXPOSURE PATHWAY ANALYSIS
Site soils contain above background concentrations of 21 base/neutral acid (BNA) organic
compounds, five volatile organic compounds (VOAs), 12 pesticide compounds, and one
polychlorinated biphenyl (PCB) compound. None were found in concentrations exceeding SCDM
benchmarks. The PCB Aroclor-1260, was detected in one sample at 150 ppb. Concentrations of
barium, calcium, chromium, copper, iron, lead, mercury, nickel, sodium and zinc were detected
over three times background. None were above SCDM benchmarks. However, lead has no
established SCDM benchmark. Lead was detected at 2,610 mg/kg in the northern corner of the
Expanded Site Investigation Work Plan Utah DEQ/DERR
Redwood Road Dump UTD980961502
Page 6
western landfill (DERR, 2001). Arsenic was reported in all soil samples collected from the
western landfill. The highest reported concentration was 43.9 mg/kg (DERR, 2001).
Soil samples were collected during installation of the direct push groundwater samples and from
selected trench locations across the Site. Soil samples were collected directly at the soil/water
interface. Lead was reported in samples at concentrations from 1,760-1,930 mg/kg. Polynuclear
aromatic hydrocarbon compounds were detected in a trench cut along the central portion of the
east bench. Soil samples collected from the base of a 10 foot trench cut revealed benzo (a) pyrene
at 5,000 pg/kg and dibenz (a,h) anthracene at 1,000 pg/kg (DERR, 2001). The SCDM CRSC for
both compounds is 20 pg/kg (SCDM, 2014). The CRSC for benzo (a) pyrene was exceeded in five
samples collected from the western portion of the landfill ranging from a high of 5,000 pg/kg to a
low of 34 pg/kg. No VOCs, semivolatile organic compounds (SVOCs) or PCBs/Pesticides were
detected in any other samples above SCDM benchmarks.
Eleven BNA, six pesticide and two VOC compounds were detected in sediment samples. The
majority of these contaminants were detected in the now nonexistent North Ditch, indicating they
most probably originated from the landfill. The North Ditch sediment sample contained three
metal concentrations that were more than three times the concentrations found in the upgradient
City Drain sediment sample. These metals include lead (68.2 mg/kg), magnesium (33,000 mg/kg)
and zinc (222 mg/kg) (DERR, 1992). There is no on-site population or residences at the Redwood
Road Dump. There are no schools or day cares located within 200 feet of the Site (DERR 2010a).
3.5.3 GROUNDWATER EXPOSURE PATHWAY ANALYSIS
Sampling results from the June 2000 TBA revealed pentachlorophenol in one groundwater sample
at an estimated concentration of 3 pg/L. The drinking water MCL for this compound is 1 pg/L.
No other organics were detected in the groundwater above SCDM benchmarks (DERR, 2001;
SCDM, 2014).
Arsenic was detected in many groundwater samples above the MCL of 10 pg/L. Arsenic was
detected at two locations north of the western landfill at 1,290 pg/L and 1,000 pg/L. Dissolved
arsenic was reported in groundwater collected from the middle of the eastern landfill at an
estimated concentration of 1,170 pg/L. Other groundwater samples ranged from 2.4 pg/L to 236
pg/L. No other dissolved metals were detected in the groundwater above SCDM benchmarks
(DERR, 2001; SCDM, 2014).
Seventeen municipal wells from three cities are located within the four-mile target distance range.
All wells are located east or south of the Site and hydraulically upgradient (DDW, 2010a; DDW,
Expanded Site Investigation Work Plan Utah DEQ/DERR
Redwood Road Dump UTD980961502
Page 7
2010b). All three city water systems are blended with multiple groundwater and surface water
sources. Approximately 4,102 underground points of diversion are located within four miles of
the Site. The uses for the large majority are for "domestic" or irrigation purposes and most are
upgradient of the Site. All downgradient wells within three miles of the Site are from 200 to 400
feet deep artesian wells drawing from the deeper, confined aquifer. All downgradient wells are
privately owned and are not used for drinking water (DWR, 2010).
3.5.4 SURFACE WATER PATHWAY ANALYSIS
There are no surface drinking water sources within the 15-mile target distance limit from the Site.
Surface waters are not used for fishing within 15-downstream miles. A wetland environment
exists at the Great Salt Lake which is approximately 10 miles downstream of the Site.
Approximately 50 miles of wetland frontage occur within the 15-mile target distance limit (USDI,
1990). Several duck hunting clubs are located within these wetland areas (DWLR, 2010).
In the 2000 TBA, lead was not detected in the upgradient sample and detected at 56.1 |ag/L in the
downgradient sample. The CMC for lead is 65 pg/L and the CCC for lead is 2.5 pg/L. No other
metal was reported above SCDM benchmarks. Arsenic was also detected in the upgradient City
Drain sample at 61 pg/L and in the downgradient sample at 82.8 pg/L (CMC = 340 pg/L, CCC =
150 pg/L).
3.5.5 AIR EXPOSURE PATHWAY ANALYSIS
There is no on-site population or residences at the Redwood Road Dump. There are no schools or
day cares located within 200 feet of the Site. There is a population of 130,095 within the four-mile
Target Distance Limit (DERR, 2010b). Both western and eastern landfills are fenced. Two means
of access are available to the eastern landfill; one is from the north through a gate which is locked
at night, and one is from the south through a road barrier.
4.0 DATA QUALITY OBJECTIVES
The EPA Data Quality Objective (DEQ) Process is a seven-step planning approach used to prepare
plans for environmental data collection activities. It provides a systematic approach for defining
the criteria that data collection design should satisfy. Surface water exposure is the pathway of
highest potential concern for the Site. Air and groundwater pathways are of lesser concern.
Expanded Site Investigation Work Plan Utah DEQ/DERR
Redwood Road Dump UTD980961502
Page 8
STEP ONE - THE PROBLEM STATEMENT
Lead in surface water, has been detected at a level significantly exceeding SCDM screening levels.
Arsenic has also been detected in surface water at about half the SCDM benchmark. No surface
water or sediment samples have been collected from downgradient surface waters to determine
potential threats to downgradient sensitive environments. Total water hardness has not been
determined to permit accurate determination of SCDM hardness based on environmental
benchmarks.
STEP TWO - IDENTIFYING THE DECISIONS
Are Site contaminants present in surface water or sediments at levels that could pose a threat to
downgradient sensitive environments?
STEP THREE - IDENTIFYING THE DECISION INPUTS
Field and laboratory analytical results from surface water and sediment upgradient and
downgradient samples will form the basis for making subsequent decisions. Surface water total
hardness analytical results will be used to calculate SCDM hardness based environmental
benchmarks. Analytical results from surface water will be compared to SCDM environmental
benchmarks. Analytical results from sediment samples will be compared to background
concentrations to determine if an "observed release" of contaminants is present.
STEP FOUR - DEFINE THE STUDY BOUNDARIES
Surface water and sediment samples will be collected upgradient of the Site and downgradient of
the Site at locations before and after the City Drain merges with several downgradient canals
before entering sensitive environments at the Great Salt Lake. Co-located sediment samples will
also be collected.
STEP FIVE - DEVELOPING DECISION RULES
In general, sample results will be compared to background samples and to SCDM benchmarks to
determine if potential environmental threats exist. Contaminant concentrations in upgradient and
downgradient samples will be used to further identify the extent of contamination.
STEP SIX - DEFINING TOLERANCE LIMITS ON DECISION ERRORS STEP
Judgmental sampling will be used to bias samples toward more potentially contaminated areas.
Statistical sampling will not be used and the tolerance limits on decision errors will not be
Expanded Site Investigation Work Plan Utah DEQ/DERR
Redwood Road Dump UTD980961502
Page 9
calculated. All analytical data will be reviewed, verified and validated to ensure data are
acceptable for the intended use.
STEP SEVEN - OPTIMIZING THE SAMPLE DESIGN
Sample locations may be adjusted based on utility clearances or other field factors. Site maps,
updated with the results from previous sample studies, will be used to determine the number and
location of potential source sample locations. The surface water sample used for determining total
water hardness will be collected at a location that accurately represents the quality of water
flowing from the Site into sensitive environments.
5.0 FIELD PROCEDURES
5.1 CONCEPT OF OPERATIONS
5.1.1 SCHEDULE
Sampling for this ESI is tentatively scheduled for spring or summer 2015 and is contingent upon
the EPA's approval of this Work Plan. Field activities are expected to last one to two days
depending on conditions at the Site. Coordination with the landowners, lessees, laboratories, and
local health authority is on-going and concurrent with this Work Plan. All logistical functions will
be arranged by the Project Manager in advance of sampling.
5.1.2 SAFETY
On-site personnel will avoid direct dermal contact, inhalation, and ingestion of potentially
contaminated materials. Sampling will be conducted in Level D personal protective equipment
unless the Site Health and Safety Officer, upon evaluation of Site conditions, deems an upgrade
necessary. A detailed Health and Safety Plan (HASP) has been prepared and will be reviewed with
field personnel prior to the beginning of any fieldwork (Appendix A). A Tailgate Safety Meeting
form will be provided and reviewed by all personnel prior to start of activities each field day.
In the event of an accident, the nearest hospital is the LDS Hospital (801-408-1100) located at 325
East 400 North (8th Avenue), Salt Lake City, Utah. A map of the route to the hospital from the Site
has been included with the HASP in Appendix A.
Expanded Site Investigation Work Plan Utah DEQ/DERR
Redwood Road Dump UTD980961502
Page 10
5.1.3 SITE ACCESS AND LOGISTICS
Site access will be arranged by the Project Manager. The landowners/lessees will be asked to sign
a "Consent For Access to Property" form (Appendix B) prior to sampling. Any additional
logistical functions will be arranged by the Project Manager.
5.2 SAMPLE LOCATIONS
Surface water and sediment samples will be collected from the locations identified in Tables 1 and
2 and Figure 4. Samples will be collected to fill data gaps in the Conceptual Site Model given in
Figure 3 and to augment the existing data. Figure 4 identifies sampling locations for surface water,
and sediment. Surface water and sediment samples are located to identify the level of
contaminants immediately upgradient and downgradient of the Site and to identify contaminant
contributions by other streams entering the 15-mile downstream pathway and delivered to Great
Salt Lake sensitive environments. Sample locations may be adjusted in the field because of
utilities or other Site conditions that make the proposed sampling points inaccessible. Deviations
from this Work Plan will be documented in the field notes by the Project Manager and noted in the
ESI Analytical Results Report.
5.2.1 SOIL SAMPLES
Previous investigations have adequately characterized soil contaminants on and near the Site. No
additional soil samples will be collected as a part of this investigation.
5.2.2 GROUNDWATER SAMPLES
Previous investigations have adequately characterized groundwater contaminants on and near the
Site. No additional groundwater samples will be collected as a part of this investigation.
5.2.3 SURFACE WATER AND SEDIMENT SAMPLES
Surface water and sediment samples will be collected in the locations identified in Tables 1 and 2
and Figure 4 to identify the extent to which the Site contributes to surface water contamination in
the City Drain canal and to determine contaminant concentration downgradient as surface water
flows to the Great Salt Lake and sensitive ecosystems.
Expanded Site Investigation Work Plan Utah DEQ/DERR
Redwood Road Dump UTD980961502
Page 11
5.3 SAMPLING METHODS
The locations of the samples have been selected based on previous Site sample results and the
location of human and environmental targets. A description of the proposed samples is included in
Tables 1 and 2. The Tables provide the following information;
• Table 1 lists sample locations and rationale.
• Table 2 is a sample analysis checklist that denotes the laboratory parameters for the
analysis of each sample.
Sampling will proceed according to methods outlined in the DERR CERCLA Quality Assurance
Project Plan (QAPP) of September 2014 and other relevant EPA guidance documents. All
sampling events will be documented in a field log book including data such as: date, time, sample
number, geographic coordinates, sediment grain size and sediment percent organic content. A
photograph will be taken of each sample location. Field conditions may necessitate a deviation of
sampling methods from those presented in the Work Plan. Such deviations will be noted in the
field notes and reported in the ESI Analytical Results Report. All samples will be collected using
the appropriate number and type of sampling containers as specified by EPA Contract Laboratory
Program (CLP) guidance. All sample collection will proceed following strict chain-of-custody
procedures.
5.3.1 SOIL
Collection of soil samples is not anticipated.
5.3.2 GROUNDWATER
Collection of groundwater samples is not anticipated.
5.3.3 SURFACE WATER AND SEDIMENT
All safety protocols are detailed in the Health and Safety Plan (Appendix A). Downstream
locations will be sampled first to prevent fugitive sediments from flowing downstream and
impacting sample results. Water samples will be collected before sediment at each sample
location, taking care not to disturb the underlying sediments. Surface water samples will be
collected by placing a one-liter polyethylene sample container, or if necessary, a dipper directly
into the surface water body. Water will be poured from the dipper into the sample container. If
used, the dipper will be field decontaminated after use by washing the dipper in tap water and
Expanded Site Investigation Work Plan Utah DEQ/DERR
Redwood Road Dump UTD980961502
Page 12
Alconox followed by a rinse in tap water and a final rinse in deionized water. A dipper rinse water
sample will be collected to determine the efficacy of decontamination procedures. Sediment
samples will be collected using dedicated stainless steel spoons. The sediment will be placed
directly into a 250-mL glass jar. Water will be decanted from the jar. Spoons will be
decontaminated at DEQ for reuse in other Site sampling efforts by washing in tap water and
Alconox and rinsing in deionized water.
5.4 INVESTIGATION DERIVED WASTE
The generation of investigation derived waste (IDW) is not anticipated. Should any IDW be
collected, it will be disposed of in accordance with state and federal regulations and guidelines.
Disposable sampling equipment will be removed from the Site and disposed of as a non-hazardous
waste. Excess sample quantities will be returned to the original location.
5.5 ANALYTICAL PARAMETERS
Eight water samples will be collected for total metals analysis. These sample will be preserved
with nitric acid (HNO3). A water sample will also be collected for total water hardness analysis
expressed in mg/L calcium carbonate (CaCOa). This sample will be collected from the Sewer
Canal at the point the canal crosses the North Salt Lake Center Street. The total water hardness
sample will be passed through a 0.45-micron filter, using a pressurized bailer or peristaltic pump,
and preserved with hydrochloric acid to a pH of less than 2. Surface water and sediment samples
will also be preserved by cooling with ice to 4° Celsius. Samples to be analyzed for total metals
will be shipped to a CLP laboratory and analyzed under Routine Analytical Services (RAS). The
sample to be analyzed for total hardness will be shipped to a laboratory identified by EPA. All
samples will be analyzed according to EPA approved methods.
FIELD QUALITY CONTROL AND ASSURANCE PROCEDURES
Samples will be handled and preserved as per the criteria of the DERR QAPP of September 2014.
Appropriate background, field and laboratory duplicate samples will be collected.
CHAIN-OF-CUSTODY
Chain-of-Custody forms will be prepared with the EPA approved "Scribe" software. Samples will
be handled and delivered to the CLP laboratory in accordance with the chain-of-custody protocol
as prescribed in the DERR QAPP of September 2014.

APPENDIX A
HEALTH AND SAFETY PLAN
Site Health & Safety Plan
Redwood Road Dump
2000 West Indiana Avenue
Salt Lake City, Utah
Spring 2014
A. Site Hazard Evaluation
The contamination most likely to be encountered at the site would be from contaminated
surface water and sediment from site runoff. No other known environmental hazards
exist at the site. The primary exposure pathways are ingestion of contaminated water and
sediment by hand to mouth. No special site entry procedures will be necessary.
B. Site Investigation Team - Responsibility
Neil Taylor Project Manager
Kim Vieweg Site Health & Safety Officer
C. Personal Protection Equipment (PPE)
Based on the minimum exposure expectation at the Site, level D PPE will be worn by
workers at all times. Modifications of the protection level are not expected, however,
level C PPE should be available for use at the site if deemed necessary. This
determination will be made by the Site Safety Officer. Hip boots and a life vest will be
worn whenever collecting sediment or surface water samples near canals. A body
harness and safety line will be used to tie off the sampler where canal banks are steep.
Work should not be performed during or after rain or snow that could make canal banks
slippery.
D. Surveillance and Monitoring Equipment
On-site air monitoring will not be required based on characteristics and concentrations of
likely exposure. An upgrade to Level C PPE will be conducted, if necessary.
E. Disposal of Investigation Derived Material
Decontamination solutions and used PPE will be properly stored and disposed of.
F. Emergency Information
