EXECUTIVE SUMMARY

SITE ENVIRONMENTAL HISTORY
This report presents the results of a Phase II Environmental Site Assessment (ESA) conducted
within the South Valley Water Reclamation (SVWR) property, located northeast of the intersection
of Highway 111 and 11800 South in South Jordan, Utah (Site) on behalf of SOJO118, LLC
(Client). The purpose of the investigation was to assess the recognized environmental conditions
(RECs) identified at the Site in the Phase I ESA prepared by Kleinfelder (Document
No. SLC19R99955, dated August 21, 2019). Kleinfelder also conducted a limited Phase II ESA
of the property (Kleinfelder, 2020); the results of which are incorporated into this revised Phase II
ESA report. The Site location is presented on Figure 1. The Site features, as identified in the
Phase I ESA, are presented on Figure 2.

The Site is approximately 187 acres in size and is owned by SVWR. A Trans-Jordan Landfill
composting and maintenance facility is located in the north portion of the Site and an inactive,
permitted sewage disposal facility (Lark Monofill) is located in the south portion of the Site. The
Bastian Ditch formerly traversed the approximate center of the Site, generally oriented from north
to south. Mining-related water from Bingham Canyon was gravity fed through the Bastian Ditch
from at least 1937 through approximately 1985. The mine water carried tailings and sediment
known to have contained elevated levels of lead and arsenic. The Bastian Ditch is designated
Operable Unit 5 (OU5) of the Kennecott South Zone Comprehensive Environmental Response,
Compensation and Liability Act (CERCLA) Site. The former ditch alignment has been obscured
due to redevelopment of the Site for the composting facility and sewage disposal operations.
Based on our historical research and Site characterization, metals-impacted soil from the
Bastian Ditch remain on Site in the former ditch location.

In addition, a railroad line (the Lark Spur) was formerly located adjacent to the west of the Site
from at least 1937 through the late 1970’s or early 1980’s. The former Lark Spur railway alignment
is included as part of the Lark Waste Rock and Tailings OU6. Slag was historically used as ballast
for the railroad lines in the vicinity of the Site and elevated concentrations of lead and arsenic
were identified in some of the railroad ballast. The railroad tracks and ballast material appears to

20201466.004A / SLC20R105847_R2 Page 2 of 27 June 2, 2020

have been removed from property west of the Site. No evidence of slag was observed on the
ground surface near the western Site boundary.

SITE CHARACTERIZATION ACTIVITIES
The purpose of this investigation was to assess the potential presence of elevated levels of lead
and arsenic at the Site associated with the former Bastian Ditch and to investigate the potential
presence of petroleum hydrocarbons near the maintenance facility’s underground storage tank
(UST), oil/water separator (OWS), former drum storage area, and septic system. Kleinfelder’s
scope of services included a review of historical aerial photographs, preparation of the
investigation work plan, excavation of 12 trenches perpendicular to the buried Bastian Ditch,
advancement of vertical soil borings across the Site, excavation of test pits along the eastern Site
boundary, and laboratory analysis of soil samples.

FINDINGS
Elevated lead and arsenic concentrations were detected in the Bastian Ditch trench soil samples
from the ground surface to depths ranging from 3 to 9 feet below ground surface (bgs). Soil
samples from nine of the ten Bastian Ditch trenches where lab samples were collected, had lead
and/or arsenic concentrations above the Unrestricted Land-Use Standards of 500 milligrams per
kilogram (mg/kg) lead and 50 mg/kg arsenic. Two of the trenches contained hazardous
concentrations of lead.

The soil samples collected from the shallow flood plain and soil berm did not contain
concentrations of lead and arsenic above the Unrestricted Land-Use Standards of 500 mg/kg lead
and 50 mg/kg arsenic.

Soil samples collected near the east property boundary contained lead and/or arsenic
concentrations exceeding the Unrestricted Land-Use Standards in four geoprobe borings and five
trenches. The elevated metals concentrations were generally identified near the eastern property
fence line and did not extend westward into the Site property more than 10 to 15 feet.

20201466.004A / SLC20R105847_R2 Page 3 of 27 June 2, 2020

No petroleum hydrocarbon impacts were identified in soil samples collected from the borings near
the UST, OWS, septic tank or leach field. No chlorinated solvents or volatile organic compounds
were detected in soil near the septic system. Oil concentrations below the Utah Division of
Environmental Response and Remediation (DERR) initial screening levels (ISLs) were detected
in surfaced soil near the former drum storage area.

RECOMMENDATIONS
Since metals concentrations were identified in the Bastian Ditch sediments that exceed the
Unrestricted Land-Use Standards for lead and arsenic, and the proposed Site redevelopment has
the potential to expose soil with elevated lead and arsenic concentrations, a soil removal plan will
be developed to mitigate potential exposure to metal-impacted soils during redevelopment of the
Site. The plan will include additional characterization activities, contaminant removal, and
post-removal soil confirmation sampling.

INTRODUCTION

Kleinfelder has prepared this report to present the results of a Phase II Environmental Site
Assessment (ESA) conducted at the South Valley Water Reclamation (SVWR/Owner) property
known as the Lark Monofill, located northeast of the intersection of Highway 111 and 11800 South
in South Jordan, Utah (Site) on behalf of SOJO118, LLC (Client). The Site location is presented
on Figure 1 and is approximately 187 acres in size. Kleinfelder understands that the Client is
considering purchasing the property for redevelopment. The Site location is presented in
Figure 1. Site details are presented in Figure 2.

Investigation activities were conducted to assess findings of the Phase I ESA conducted by
Kleinfelder in 2019, and for compliance purposes with Salt Lake County Contaminated Soils
Ordinance, Title 9 Chapter 9.5. Site investigation activities included assessment of the potential
presence of elevated levels of lead and arsenic at the Site associated with the former Bastian
Ditch (Ditch) and potential soil impacts near the maintenance facility’s UST, OWS, and septic
system. Kleinfelder’s scope of services included a review of historical aerial photographs,
preparation of the investigation work plan, excavation of 12 trenches perpendicular to the buried
Bastian Ditch, advancement of vertical soil borings across the Site, excavation of test pits along
the eastern Site boundary, and laboratory analysis of soil samples in accordance with our work
plan (Document No.: SLC19O102067), dated October 8, 2019.

SITE HISTORY
The Site was used for dry farming from at least 1937 through 1985, with mining-related waters
transported through the Bastian Ditch, crossing the Site from north to south, for downstream
irrigation. The Bastian Ditch is designated Operable Unit 5 (OU5) of the Kennecott South Zone
CERCLA Site. The Bastian Ditch sediments have been identified in other off-Site locations as
containing elevated concentrations of lead and arsenic. The ditch alignment is no longer evident
on the ground surface of the Site. No records were identified of the Site being irrigated using water
from the Bastian Ditch. The former Bastian Ditch alignment is visible on the 1937 aerial
photograph, included as Figure 3.

20201466.004A / SLC20R105847_R2 Page 5 of 27 June 2, 2020

The Bastian Ditch Drainage Area, located directly east of the southern half of the Site, was
historically flood-irrigated for crop production via a series of small irrigation ditches. The irrigation
water was transported to the Drainage Area from the main Bastian Ditch alignment by a ditch
located north of the northern Lark Monofill Site boundary. Bastian Ditch water may have also
entered the Drainage Area via a Bastian Ditch tributary that crossed the Site flowing southeast as
shown on Figure 3. The Bastian Ditch Drainage was identified as containing elevated lead and
arsenic in shallow soils during several investigations conducted by Kennecott Utah Copper and
Kleinfelder.

In 2016 Kennecott representatives performed corrective action for portions of the Bastian Ditch
Drainage soils via over excavation and off-site disposal of soils identified as containing lead and
or arsenic above the Unrestricted Land-Use Standards (Rio Tinto, 2016). According to the
2016 Soil Removal Report, 29,400 cubic yards of soil was removed for off-site disposal at
Kennecott’s Bluewater Repository. The soil that contained lead concentrations above 500 mg/kg
was generally found in shallow soil up to depths of 12 to 14 inches bgs. Soil with metals
concentrations above the Unrestricted Land-Use Standards were left in place in some locations
along the western fence line adjoining the Lark Monofill Site. Excerpts from the 2016 Rio Tinto
report are included in Appendix A.

A historical railroad line (Lark Spur) was formerly located adjacent to the west of the Site from at
least 1937 through the late 1970’s or early 1980’s. The spur is visible on the 1937 aerial
photograph (Figure 3). The former Lark Spur railway alignment is included as part of the Lark
Waste Rock and Tailings OU 6 CERCLA Site due to slag that was used for ballast, which may
contain elevated concentrations of lead and arsenic. A map illustrating OU6 and the Site’s location
relative to the Lark Spur is included in Appendix A. The railroad alignment was removed during
the OU6 corrective action activities. No evidence of slag was observed on the ground surface
near the western Site boundary.

Kennecott Utah Copper obtained an environmental covenant (EC) for a portion of the Lark Spur
directly north of the Site that corresponds with the paved road connecting the Site to the
Trans-Jordan landfill. The EC indicates contaminated material associated with that portion of the
Lark Spur is believed to remain beneath the paved road north of the Site.

In approximately 1985 to 1986, portions of the Bastian Ditch and other Site soils were excavated,
a maintenance building was constructed at the Site, composting operations were initiated by
SVWR, and the Site usage as a sewage disposal facility began. Liquid sewage transported from
the SVWR wastewater treatment plant was buried in the east portion of the Site from 1985 through
1987. In 1987 through 1999, sewage sludge from the SVWR wastewater treatment plant were
buried in trenches in the south portion of the Site. According to SVWR personnel, the trenches
were typically 3 feet wide, 10 to 20 feet deep, and 1,000 feet long, excavated on 20-foot centers
oriented east to west. Approximately 285 trenches were excavated at the Site. No sewage
disposal trenches exist beneath the composting facility or in the southwest portion of the Site
(Figure 2). The south portion of the Site (sewage disposal area) has been left inactive since
approximately 1999. Beginning in 2006, Trans-Jordan Landfill began leasing the north portion of
the Site and operating the composting facility.

A 2,000-gallon waste-oil UST was installed east of the Trans-Jordan maintenance/storage
building in 1986. The tank was converted to a heating oil UST in 1996. Soil samples were collected
in May 1996, prior to the change in service. A LUST incident (JOI) was assigned to the Site due
to contaminated soil detected at depths from approximately 4 to 12 feet below ground surface
(bgs). Based on the soil analytical results, Total Recoverable Petroleum Hydrocarbons (TRPH)
were detected in the closure soil samples at a maximum concentration of 390 mg/kg. No soil was
removed during the closure activities, and DERR did not require removal or additional
investigation of the petroleum impacts. Groundwater was not encountered during the UST closure
activities as depth to groundwater in the area is over 300 feet bgs. The LUST file was closed by
DERR in July 1996 due to the lack of encountered groundwater, the TRPH concentration in the
soil below DERR Tier 1 Screening Criteria, low permeability of the silt surrounding the UST, and
the low toxicity and mobility of TRPH. The location of the UST is presented on Figure 2.

REGULATORY BACKGROUND
The DERR has regulatory authority for contaminated soil management within the Kennecott South
Zone operable units, including the Bastian Ditch (OU5), that crosses the Site. Because SOJO118,
LLC wishes to redevelop, grade, and/or transport soils from OU5, DERR required a Site
characterization be conducted to assess whether elevated concentrations of lead and arsenic
exist in the Site soils. In addition, remediation and reuse of the sewage disposed at the Site is
regulated by the Code of Federal Regulations (CFR) 40 CFR Part 503 - Standards for the Use or

20201466.004A / SLC20R105847_R2 Page 7 of 27 June 2, 2020

Disposal of Sewage Sludge. Figures showing the extent of OU5 (Bastian Ditch), and OU6 (Lark
Waste Rock and Lark Spur) are included in Appendix A.

A 2015 joint Technical Memorandum prepared by the DERR and U.S. Environmental Protection
Agency (EPA) Region 8 (the Agencies) established soil action levels for the Kennecott North and
South Zone Operable Units, including the following standards for the Bastian Ditch (OU5):

• Agricultural Land-Use Standards – 8,500 mg/kg lead and 100 mg/kg arsenic,
• Industrial Land-Use Standards – 4,414 mg/kg lead and 261 mg/kg arsenic,
• Recreational Land-Use Standards - 2,207 mg/kg lead and 283 mg/kg arsenic,
• Unrestricted Land-Use Standards - 500 mg/kg lead and 50 mg/kg arsenic.

To allow for maximum flexibility in Site development, SOJO118, LLC intends to perform any
necessary corrective action in compliance with the Unrestricted Land-Use Standards.

CONTAMINANTS OF CONCERN
The contaminants of concern (COCs) for the Site are lead and arsenic in soil, where the Bastian
Ditch may have impacted the Site, and petroleum hydrocarbons near the UST, OWS, and septic
system associated with the Trans-Jordan maintenance building. Volatile organic compounds
(VOCs) were also assessed in the soil samples collected near the septic system to assess for the
potential present of solvents used in the maintenance building.

INVESTIGATION ACTIVITIES

In accordance with Salt Lake County Contaminated Soils Ordinance, Title 9 Chapter 9.5, because
the Site is associated with the OU5 (Bastian Ditch), a Site characterization was conducted to
assess for the presence of elevated metals. Additionally, RECs identified during Kleinfelder’s
Phase I ESA were assessed. The field investigation was conducted in October 2019 and
March and April 2020.

Prior to commencing field work, Blue Stakes of Utah Utility Notification Center (Blue Stakes) was
notified to assess the potential presence and location of buried utilities. Additionally, Kleinfelder
reviewed historical Site drawings to assess the locations of utilities and product piping and Penhall
Company, conducted an on-Site private utility locate in the vicinity of the maintenance building.
Penhall used ground penetrating radar, radio frequency, and electromagnetic locating equipment
to identify and confirm locations of subsurface utilities, the heating oil UST, the OWS, and their
respective piping.

The sampling protocols discussed below were used to investigate the potential presence of
elevated concentrations of lead and arsenic at the Site, and to investigate the potential presence
of petroleum hydrocarbons near the UST, OWS, and septic system. Potential VOC impacts were
also assessed near the septic system location. Sampling Protocol #1 (Section 3.1) was designed
to investigate areas where near surface soils may be impacted by lead and arsenic due to flood
irrigation with metals-impacted water, or where excavated Bastian Ditch sediment may have been
graded across the Site. Sampling Protocol #2 (Section 3.2) addresses buried sediments within
the former Bastian Ditch. Sampling Protocol #3 (Section 3.3) was designated to investigate for
petroleum hydrocarbons near the UST, OWS, and septic system and for VOCs near the septic
system. Sampling Protocol #4 (Section 3.4) was designated to investigate additional Client
investigation requests. Detailed procedures for sample collection, homogenization, labeling, field
records, decontamination, etc. are included in Section 3. Photographs of the Bastian Ditch
Sediments, test pit logs and boring logs are included in Appendix B.

SHALLOW SOILS AND BERM INVESTIGATION SAMPLING
Near surface soil sampling was conducted across the Site to assess for metals impacts in shallow
soil due to the possibility that mine-related water may have been used for flood irrigation of the
Site via the Bastion Ditch. However, interviews with Kennecott personnel indicated the area was
never irrigated. Soil samples were collected using a direct push drill rig in a grid pattern with
approximately 400 feet between samples across the Site, resulting in 44 boring locations.

Additionally, the sewage disposal trenching disturbed the Bastian Ditch sediments where each
trench crossed the Ditch alignment. Ditch sediments were mixed with surrounding material and
graded across the Site. The bermed material in the east portion of the Site originated from the
sewage disposal trench excavations; therefore, it was suspected to contain traces of Bastian Ditch
sediment. It should be noted that the volume of Bastian Ditch sediments disturbed by each
sewage trench excavation was minimal compared to the volume of soil excavated per trench. The
sewage trenches were excavated 10 to 20 feet and 1,000 feet long, encountering ditch sediment
the was generally 4 feet deep and 6 to 10 feet long within the trench; therefore, it is reasonable
to conclude the excavated ditch sediments would have been dispersed and “diluted” during trench
excavation. Seven borings (KS-1 through KS-7) were advanced within the excess soil stockpile
berm on the northeast portion of the sewage disposal area (Figure 4).

The borehole locations were selected in advance with the final locations dictated by the presence of
existing surface features. The boring locations were surveyed with a hand-held GPS with
sub-meter horizontal accuracy. At each grid point, one vertical-profile soil sample was collected
from a depth of 0 to 2 feet bgs. The sampler was decontaminated before use and between each
sample using a non-phosphate detergent wash with a distilled water rinse. New, factory-sealed,
Lexan sleeves were used to collect each sample. The vertical grid sample was split into a 0- to
12-inch depth and a 12- to 24-inch depth sample. Because the Site surface soils have been
graded periodically for sewage trenching and weed control, a sample interval of 0 to 12-inches
was selected to represent the “mixed” surficial soils, while the 12- to 24-inch sample represents
undisturbed soils.

20201466.004A / SLC20R105847_R2 Page 10 of 27 June 2, 2020
© 2020 Kleinfelder www.kleinfelder.com
The soil berm borings were extended to the apparent depth of the stockpile and composited into
two increments representing 0- to 5-feet bgs and 5- to 9-feet bgs. The bermed material contains
spoils from the sewage trenches. If Bastian Ditch sediments are present in the bermed material
they would have been mixed with other excavated trench sediments prior to placement in the
berm and are unlikely to contain concentrated, undisturbed Ditch sediments; therefore, this
sampling protocol was selected in order to characterize the entire vertical column of bermed
material.

Each composite soil sample was homogenized in a new, sealable plastic bag. Large debris and
rocks were removed prior to homogenization of soil. The composite sample intervals were
field-screened for the presence of lead and arsenic using a hand-held x-ray fluorescence (XRF)
instrument. The grid soil sample with the highest XRF measurement was submitted to Pace
National Analytical Laboratory (Pace) for analysis of total arsenic and lead by EPA Method 6010B.
Fifty-two samples were submitted for laboratory analysis. Figure 3 illustrates the historical Bastian
Ditch alignment and sample locations on a 1937 aerial photograph. The sample locations and
Site features are indicated on Figure 4. The XRF readings and the associated laboratory analytical
results for total lead are presented in Table 1.

BASTIAN DITCH TRENCH SAMPLING
The approximate location of the former Bastian Ditch alignment was identified in the field using
GPS coordinates obtained from the 1937 historical aerial imagery. A track-hoe was used to
excavate trenches perpendicular to the former ditch location. The purpose of the trenching was
to identify the location, depth and width of Bastian Ditch sediments remaining below grade at the
Site and to assess the concentrations of lead and arsenic in the ditch sediments. Twelve trenches
were excavated (KT-1 and KT-4 through KT-14) in accessible areas (at an average spacing of
approximately 725 feet) along the former Bastian Ditch alignment to a depth of at least 1 foot
below the apparent depth of the ditch sediments. Kleinfelder proposed to excavate two trenches
(KT-2 and KT-3) within the Trans-Jordan composting area, but SVWR requested the paved facility
not be disturbed at this time, so those locations were not assessed. The trench locations are
presented on Figures 3 and 4.

20201466.004A / SLC20R105847_R2 Page 11 of 27 June 2, 2020
© 2020 Kleinfelder www.kleinfelder.com
Each trench was excavated to the depth and width necessary to identify the lateral and vertical
extent of the ditch sediment at that location. The trench sediments were logged and field-screened
from the trench sidewalls or from excavation spoils using the XRF instrument. The dimensions of
the channel, soil discolorations, and the apparent location of the ditch sediments within the trench
were noted.

Soil samples were collected by hand in trenches up to 4 feet bgs if the soil type encountered was
stable. Soil samples from trench depths greater than 4 feet bgs were collected from spoils placed
on the surface by the track-hoe.

When visual indicators such as discoloration or sediment deposition and XRF readings showed
the apparent channel sediments, a minimum of two vertical composite soil samples were collected
representing the layer exhibiting the highest lead and/or arsenic XRF measurements, and an
additional sample was collected from the “clean” layer below the channel sediments. No samples
were collected for laboratory analysis when no apparent channel sediments were present (i.e.
Trench KT-7 and Trench KT-11). Each composite soil sample was collected using either new
disposable hand tools or decontaminated hand tools and homogenized in a new, sealable plastic
bag. Large debris and rocks were removed prior to homogenization of soil. Clay soils were
thoroughly mixed to the extent practicable. Each composite soil sample was field-screened with
the XRF to evaluate lead and arsenic concentrations. Twenty-nine soil samples from 10 trenches
were submitted to Pace for analysis of total lead and arsenic by EPA Method 6010B. After receipt
of the total metals analytical results, the five soil samples with lead concentrations exceeding
3,500 mg/kg were analyzed for lead and arsenic concentrations by the Toxicity Characteristic
Leaching Procedure (TCLP).

The excavation was backfilled with the spoils in reverse order of removal, compacted with the
bucket, and graded to match the surrounding soil. The backfill was not compacted to an
engineering standard. The trenches were logged and photographed and XRF readings were
entered on the field log at the corresponding depth. The trench locations were surveyed with a
hand-held global positioning system (GPS) unit with sub-meter horizontal accuracy.

BASTIAN DITCH INTERCEPTION WITH SEWAGE TRENCHES
During the field investigation, the Client asked Kleinfelder to field-screen soil in two test pits
(KTP-2 and KTP-10) where the Bastian Ditch crosses the sewage disposal trenches (See
Figure 4). This was conducted to assess whether metal-contaminated soil was brought to the
surface during sewage disposal trenching and backfilling operations. The test pits were excavated
to 12 feet bgs, the spoils were placed on the surface in separate piles representing vertical 2-foot
depth intervals, and the soil was field-screened using the XRF. Sewage was encountered
between 10 and 10.5 feet bgs in each test pit. The XRF readings were consistent with the native
soils monitored elsewhere on Site and elevated metal concentrations were not detected within
the vertical profile of the test pit (Table 1). Due to the lack of elevated XRF metal readings, no soil
samples from the sewage disposal areas were submitted for laboratory analysis.

Additionally, the Client asked Kleinfelder to calculate an approximate volume of soil to be removed
should all the Bastian Ditch sediment be removed from the Site in the future. Several assumptions
were made in order to quantify an approximate removal volume. These assumptions included the
following:

• At least 1 foot of over-excavation,
• The removal shape would be rectangular instead of v-shaped,
• Clean cover would be included in the removed material,
• The depth of impacted material was averaged between trench locations, and
• A 20% contingency was added to the total volume.

Using these assumptions, Kleinfelder calculated an approximate removal volume of 13,000 to
16,800 cubic yards of soil within the main Bastian Ditch alignment. Kleinfelder did not estimate
impacted soil volumes along the eastern property line

EAST/NORTHEAST PROPERTY LINES - SHALLOW SOIL SAMPLING
Kleinfelder conducted an investigation adjacent to the east and northeast property lines to assess
for impacts related to the Bastian Ditch Drainage Area, which is located adjacent to the eastern
Site boundary. Forty-nine locations (KE-38 though KE-86) were assessed using a direct-push drill
rig and excavator, and 59 soil samples were submitted for laboratory analysis. An additional nine

samples were collected that showed yellow-staining indicative of Bastian Ditch sediments (labeled
KE-#BD to represent Bastian Ditch sediment). The locations where yellow-stained sediments
were observed on the east property line are presented in Figure 5. The initial samples were
collected within 5 to 10 feet of the fence line. Where metals-impacted soil was evident, additional
samples were collected moving westward into the Site, to identify the lateral, western extent of
impacted soils near the eastern property line that are associated with the Bastian Ditch Drainage.
The investigation focused on the upper 5 feet of soil because the metals-impacted soil in the
Drainage area was generally identified within the upper 12 to 14 inches. The east property line
sample locations are presented on Figure 5.

It should be noted that some of the boring identification numbers for this task do not match the
laboratory analytical reports. The identification numbers were renamed from KB-XX to KE-XX to
reflect the sample location and eliminate duplicate sample IDs for KB-38 through KB-45. For
instance, on the laboratory analytical report, the east side sample identified as KB-40 is identified
in this report as KE-40. The sampling methodology for the direct-push and excavated trenches
is described below.
3.4.1 East Side Direct-Push Soil Sampling
A direct push drill rig was used to advance ten soil borings (KE-38 through KE-47) along the south
half of the eastern Site boundary adjacent to the area excavated during the Bastian Ditch
Drainage soil removal activities (Figure 5). The borings were spaced 100 feet apart, and each
boring was located approximately 10’ west of the eastern fence line. Each boring was advanced
to 5 feet bgs. Soil samples were collected from the 0 to 2.5-foot and 2.5 to 5-foot intervals in each
boring. The drilling and sample collection activities were performed in the same manner as
described in Section 3.1 of this report. Two samples from each boring (20 total samples) were
submitted to Pace for laboratory analysis of total lead and total arsenic by EPA Method 6010B.
3.4.2 East Side Trench Soil Sampling
From April 2 through April 6, 2020 Kleinfelder excavated an additional 39 shallow trenches
(KE-48 through KE-86) along the northern and northeastern Site boundaries (Figure 5). The test
pits were spaced on approximate 100-foot intervals. Each test pit was excavated to a total depth
between approximately 4- and 9-feet bgs. In each test pit, one soil sample was collected from the
0- to 2-foot interval (labelled “A” series) and a second soil sample was collected from 2- to 4-foot

20201466.004A / SLC20R105847_R2 Page 14 of 27 June 2, 2020

interval (“B” series). In test pits where a yellow sediment layer (indicative of metals-impacted
sediment) was observed, a third soil sample was collected from the yellow-stained soil and given
a “BD” suffix (indicating suspect Bastian Ditch Drainage sediment).

The yellow-stained material was generally encountered near the fence line and was observed to
“pinch out” within approximately 8 to 10 feet of the east fence. In one location (KE-54), the yellow
staining was not encountered until 8 feet west of the fence line and extended at least 4 feet
underneath the dirt road (extending approximately 12 to 20 feet from the fence). In every trench,
non-stained soil was observed to the west of the stained interval. Thirty-nine (39) soil samples
and nine (9) yellow-stained sediment samples collected from the test pits were submitted to Pace
for laboratory analysis of total lead and total arsenic by EPA Method 6010B. The soil boring and
test pit locations are presented on Figure 5.

UST AND OIL/WATER SEPARATOR SUBSURFACE SAMPLING AND INSPECTION
Kleinfelder’s Phase I ESA (Kleinfelder, 2020) identified the heating oil UST, located east of the
maintenance building, as a CREC. SVWR indicated that they do not know whether heating oil is
currently stored in the UST. As detailed in the Site Phase I ESA, the subsurface soil surrounding
the UST was assessed in 1996 and a limited petroleum release was identified. The release file
was subsequently by DERR with no further action. Kleinfelder advanced two borings (B-1 and
B-2) using a direct-push drill rig to 15 feet bgs adjacent to the UST to assess the current
subsurface conditions. The boring locations are presented on Figure 6. The soils were monitored
for organic vapors using a photo-ionization detector (PID) and inspected for petroleum staining
and odor. No indications of petroleum impacts were identified in either boring.

Based on the lack of apparent soil impacts, only one soil sample (from boring B-1) was selected
for laboratory analysis to confirm the field findings. The sample was collected from the 10 to
15-foot depth interval to characterize soil beneath the UST and because this was the only location
where darker, possibly petroleum-stained soil was observed in either boring. The sample was
laboratory-analyzed for Total Petroleum Hydrocarbons (TPH) as gasoline-range organics
(TPH-GRO), diesel-range organics (TPH-DRO) and oil-range organics (TPH-ORO) by EPA
Method 8015. The boring logs are included in Appendix B.

20201466.004A / SLC20R105847_R2 Page 15 of 27 June 2, 2020
© 2020 Kleinfelder www.kleinfelder.com
An OWS, observed inside the maintenance building near the south wall, was also identified as a
potential source of environmental concern. Kleinfelder advanced one boring (B-3) to 15 feet bgs
adjacent to the OWS. The soil was logged and screened with the PID for organic vapors. No
organic vapors were detected, and no soil staining was observed in the soil boring. The boring
log is included in Appendix B.

In March 2020, Kleinfelder inspected the OWS and the associated drains and sumps in the
maintenance building. Two trench drains run the length of the building, and one three-chamber
sump is located in the wash bay, as indicated on Figure 6. Kleinfelder was unable to observe
where the piping runs due to dirt and debris clogging the pipes, but it is likely that the trench drains
and sump direct water to the OWS. During the initial inspection, Kleinfelder was unable to observe
the inlet or outlet of the OWS because it was full of oil, water, and sludge. Kleinfelder retained the
services of Sump and Trap, LLC to remove the fluids and clean the OWS. Sump and Trap first
performed a chlor-detect test which was negative, indicating that no chlorinated solvents were
present in the fluid at detectable concentrations. After the OWS was cleaned out, Kleinfelder was
able to observe an inlet and an outlet in the OWS. Based on our observations, it appears that the
OWS drains to the septic system, located southwest of the maintenance building. The oil, water,
and sludge from the OWS were recycled by Sump and Trap at their Salt Lake City facility.

AST AND DRUM STORAGE AREA INSPECTION AND SAMPLING
Two above ground storage tanks (ASTs) are located north of the maintenance building. Both
tanks have built-in secondary containment; one is a concrete-encased, steel walled tank, and the
other is a double-walled steel tank. The double-walled steel tank is placarded as empty. The tanks
are installed on a concrete pad that was observed to be in good condition with no stains or cracks
observed during the March 2020 field activities.

Additionally, Kleinfelder inspected the area to the east of the ASTs, where 55-gallon drums were
previously observed to be stored. As reported in the Site Phase I ESA report, the drums were
previously observed to be empty, and were reportedly used for the annual landfill rodeo. No
staining was noted on the bare soil at the edge of the asphalt; however, light staining was
observed on the asphalt surface. Kleinfelder collected a five-point composite soil sample
(LARK-SS1) from the near-surface soil adjacent to the stained asphalt. A composite sample was
collected to assess the ground surface in the general vicinity of the former drum storage area

20201466.004A / SLC20R105847_R2 Page 16 of 27 June 2, 2020
© 2020 Kleinfelder www.kleinfelder.com
because no obvious area of soil impact was observed that would be appropriate for a targeted
grab sample. The soil sample was submitted to Pace for analysis of total petroleum hydrocarbons
as gasoline range organics (TPH-GRO), TPH as diesel range organics (TPH-DRO), TPH as oil
range organics (TPH-ORO), Resource Conservation and Recovery Act (RCRA) – 8 metals, and
VOCs. The composite soil sample location is shown on Figure 6.

LEACH FIELD SAMPLING
Kleinfelder used Site drawings provided by SVWR (included in Appendix B) and Site observations
to identify the location of the septic tank and leach field. On March 16, 2020, Kleinfelder advanced
nine soil borings (KS-29 through KS-37) in the leach field and septic tank area using a direct push
drill rig. Each boring was advanced to refusal, which was typically encountered around 9.5’ bgs
in gravel. Kleinfelder’s field engineer observed a dark brown soil layer in most of the borings
between approximately 2 and 4 feet bgs. The dark layer did not have an odor or elevated PID
readings and appeared to be organic material related from the leach field piping. Soil samples
from five of the borings were selected from the dark brown soil interval to be submitted for
laboratory analysis of TPH-GRO, TPH-DRO, TPH-ORO, VOCs, total lead, and total arsenic. The
drilling and sample collection were performed in the same manner as described in Section 3.1 of
this report. The leach field boring locations are presented on Figure 6.

ANALYTICAL RESULTS

The analytical results obtained from the Site investigation are presented below. Copies of the
laboratory analytical reports and chain of custody documentation are included in Appendix C. The
soil analytical results were compared to the following regulatory standards: DERR Initial
Screening Levels for petroleum hydrocarbons and VOCs; the Unrestricted Land-Use Standards
for lead and arsenic of 500 mg/kg and 50 mg/kg, respectively; OU5 Recreational Land-Use
Standards for lead and arsenic of 2,207 mg/kg and 283 mg/kg, respectively. The laboratory
analytical results for the Bastian Ditch metals assessments are summarized in Tables 2 and 3,
and the analytical results for the maintenance building septic system investigation are
summarized in Table 4. Tables 5 and 6 present the quality assurance laboratory results.

SHALLOW FLOOD PLAIN INVESTIGATION RESULTS
The maximum lead and arsenic concentrations detected in the shallow flood plain soil samples
(0- to 1-foot bgs) were 241 mg/kg lead and 29 mg/kg arsenic; and averaged 96 mg/kg and
13 mg/kg, respectively. The flood plain samples collected from 1- to 2-feet bgs had maximum lead
and arsenic concentrations of 278 mg/kg and 16.2 mg/kg and averaged 111 mg/kg and 12 mg/kg,
respectively. All 44 shallow-soil flood plain samples (KB-1 through KB-12 and KB-14 through
KB-45) had metals concentrations below the Unrestricted Land-Use Standards for lead and
arsenic of 500 mg/kg and 50 mg/kg (See Table 2).

BERM INVESTIGATION RESULTS
The maximum lead and arsenic concentrations in the top five feet of bermed material (0- to 5-foot
bgs) were 164 mg/kg and 15 mg/kg and averaged 137 mg/kg and 13 mg/kg, respectively. The
material from 5- to 9-feet bgs had maximum lead and arsenic concentrations of 110 mg/kg and
16 mg/kg and averaged 99 mg/kg and 12 mg/kg, respectively. The seven berm samples
(KS-1 though KS-7) had metals concentrations below the Unrestricted Land-Use Standards for
lead and arsenic of 500 mg/kg and 50 mg/kg (See Table 2).

BASTIAN DITCH TRENCH INVESTIGATION RESULTS
Twelve trenches were excavated along the Bastian Ditch alignment (KT-1 and KT-4 through
KT-14) as shown in Figures 3 and 4. The Bastian Ditch metals-impacted sediments were visually
evident in the trenches due to their yellow-orange staining. The Bastian Ditch metals-impacted
sediments were evident in ten of the twelve trenches excavated but were not identified visually or
with the XRF in trenches KT-7 and KT-11. Trench KT-7 was excavated within a surface drainage
area that does not appear to be associated with the Bastian Ditch. Trench KT-11 was located
within a side drainage not associated with the Bastian Ditch that was identified in the 1937 aerial
photograph. Twenty-nine soil samples from the ten trenches containing Bastian Ditch sediments
were submitted for laboratory analysis.

The top of the Bastian Ditch channel sediments were found on average between 2 to 2.5 feet bgs,
but were as shallow as directly at the ground surface (KT-5) and as deep as 6.5 bgs (KT-8), based
on field observations and XRF readings. The analytical results are presented in Table 2
summarized below:

• Lead and arsenic concentrations in the Bastian Ditch channel sediments averaged
4,362 mg/kg and 287 mg/kg, respectively.
• The maximum metals concentrations were found in trench KT-1, which is located off-site
just northeast of the property line, with 25,000 mg/kg lead and 1,120 mg/kg arsenic. The
maximum metals concentrations detected in the on-site trenches were found in KT-12,
located in the far southwest corner of the Site, with 8,560 mg/kg lead and 299 mg/kg
arsenic.
• Lead concentrations exceeding the Recreational Land-Use Standard of 2,207 mg/kg lead
were present in five of the ten trenches sampled. Arsenic concentrations exceeding the
Recreational Land-Use Standard of 450 mg/kg arsenic were present in two trenches.
• Lead concentrations exceeding the Unrestricted Land-Use Standard of 500 mg/kg were
present in nine of the twelve trenches (75 percent). Arsenic concentrations exceeding the
Unrestricted Land-Use Standard of 50 mg/kg arsenic were present in six (half) of the
sampled trenches.
• Analytical results for samples collected below the visually-indicated and XRF-screened
Ditch sediment layer averaged 260 mg/kg for lead and 19 mg/kg for arsenic. The maximum

20201466.004A / SLC20R105847_R2 Page 19 of 27 June 2, 2020
© 2020 Kleinfelder www.kleinfelder.com
reading was 591 mg/kg lead and 79 mg/kg arsenic. This indicates the sediment staining
and XRF data accurately identified the depth extent of the ditch sediments.
• Samples from two trench locations (KT-1 on the far north end of the Site and KT-12 on
the far south end) had TCLP lead concentrations that exceeded the hazardous waste
threshold of 5 mg/L. Both samples exceeded 8,500 mg/kg total lead concentrations.

EAST/ NORTHEAST PROPERTY LINES - SHALLOW SOIL INVESTIGATION RESULTS
Fifty-nine (59) soil samples from 49 locations (KE-38 though KE-86) as well as 9 yellow-stained
sediment samples (KE- #BD) were laboratory analyzed from the east-side assessment. The
analytical results are presented in Table 3. The laboratory reported total lead and arsenic
concentrations in soil exceeding the Unrestricted Land-Use Standards of 500 mg/kg for lead and
50 mg/kg for arsenic in four geoprobe borings (KE-40, 43, 44 and 45 at the 0-2.5 or 2.5-5 foot
depths) and in five of the nine yellow-stained sediment samples observed in the east trenches
(see Figure 5). In each of the trenches where yellow-stained sediments were observed above
cleanup standards, “clean” soil was documented at the 0-2 and 2-4 foot depths within several feet
west of where the yellow-stained sediments were observed to “pinch out” in the subsurface. The
soils with metals concentrations exceeding the Unrestricted Land-Use Standards were generally
identified near the eastern property fence line and did not extend westward into the Site property
more than 10 to 15 feet.

The maximum lead concentration detected in the east/northeast samples was 1110 mg/kg in the
yellow-stained sample KE-54BD. The maximum arsenic concentration detected was 73.7 mg/kg
in KE-54BD. Based on the generally high lead and arsenic concentrations, the yellow-stained soil
observed in some trenches excavated along the eastern Site boundary is likely associated with
the Bastian Ditch Drainage sediment.

UST, DRUM STORAGE AREA, AND OIL/WATER SEPARATOR SEDIMENT RESULTS
TPH-GRO, TPH-DRO and TPH-ORO were not detected above laboratory reporting limits in the
soil sample collected adjacent to the UST. Elevated PID readings were not detected in the soil
samples collected adjacent to the UST or the OWS. Additionally, chlorinated solvents were not
detected in the chlor-detect test run by Sump and Trap on the OWS sludge. Based on these

20201466.004A / SLC20R105847_R2 Page 20 of 27 June 2, 2020
© 2020 Kleinfelder www.kleinfelder.com
results, no evidence of petroleum hydrocarbons or VOCs were detected in the soil samples
collected near the former UST and OWS.

TPH-ORO was reported by the laboratory in the composite sample collected from the ground
surface in the vicinity of the former drum storage area at a concentration of 663 mg/kg, which is
below the DERR ISL of 1000 mg/kg. Concentrations of TPH-DRO, TPH-GRO, methyl tertiary
butyl ether (MTBE), benzene, toluene, ethylbenzene, total xylenes, naphthalene (MBTEXN) were
not detected above the laboratory reporting levels. Concentrations of lead and arsenic were also
below the Unrestricted Land-Use Standards.

LEACH FIELD INVESTIGATION RESULTS
The laboratory did not detect TPH-GRO, TPH-DRO, TPH-ORO, MBTEXN, tetrachloroethylene
(PCE), trichloroethylene (TCE), or vinyl-chloride (VC) at concentrations above the laboratory
reporting limits for the five soil samples submitted for laboratory analysis. Based on the laboratory
analytical data, no evidence of petroleum or chlorinated solvent contamination appears to be
present in the septic system location. Arsenic and lead were each reported at concentrations
below the Unrestricted Land-Use Standards. Based on historical aerial photography, the Bastian
Ditch channel is located east of the septic tank and leach field, as illustrated in Figure 6. The Ditch
sediments in that area are anticipated to remain intact and were likely not disturbed during
installation of the leach field.

DATA QUALITY OBJECTIVES AND QA/QC

FIELD QUALITY ASSURANCE/QUALITY CONTROL
Quality Assurance (QA) and quality control (QC) procedures associated with the subsurface
investigation were implemented to produce data that are accurate, credible, and representative
of conditions at the Site. Kleinfelder’s QA/QC procedures for this project included:

• Careful record keeping and documentation;
• Use of appropriate equipment and decontamination procedures;
• Split Quality Assurance samples;
• Documentation of Chain-of-Custody; and
• The samples were submitted to PACE, a state certified laboratory, which follows QA/QC
procedures consistent with USEPA standards. Laboratory QA/QC samples included
method blanks, matrix spikes, duplicates and calibration check samples. QA statements
for the lab samples are included with the laboratory reports in Appendix C.

Quality control for the sampling program included using standardized sample collection and
handling methods, documenting pertinent field information, and keeping chain-of-custody records
as prescribed herein. Single-use, disposable sampling tools were used for sample collection, or
non-disposable sampling equipment was decontaminated between each sample location.

DATA QUALITY ASSESSMENT REVIEW
The purpose of data quality assessment is to assure that data generated under the QA/QC
program is reconciled, accurate and consistent with program data quality objectives (DQOs). The
quality of the data was assessed based on precision, accuracy, completeness,
representativeness and comparability. The collected samples were analyzed for total arsenic and
lead, petroleum hydrocarbon constituents and volatile organic compounds. The primary lab used

20201466.004A / SLC20R105847_R2 Page 22 of 27 June 2, 2020
© 2020 Kleinfelder www.kleinfelder.com
was Pace Analytical (Pace) and the secondary lab used was American West Analytical Labs
(AWAL).

A review of the laboratory analytical reports indicated all sample analyses were performed within
holding times, the samples were analyzed following the correct methods, all instruments and
calibration check requirements were met, and the method blanks did not report concentrations of
either lead or arsenic.

Precision is the degree to which a measurement is reproducible and is quantitatively measured
by calculating the Relative Percent Difference (RPD) of two measurements. Precision in terms of
the RPD was evaluated on an inter-laboratory and intra-laboratory basis. RPD is defined as:

RPD= [(A1-A2)/((A1+A2)/2)]*100

Where • A1 = Analytical result from laboratory #1
• A2 = Analytical result from laboratory #2

Intra-laboratory precision was assessed by calculating the RPD between the original sample and
its’ field duplicate. One out of every 10 samples collected for lab analysis was split two ways for
a total of eight duplicate samples. The samples were split with one portion submitted as a standard
analytical sample and one portion as a blind duplicate to be analyzed at the primary lab (Pace).
The data quality objective for the split sample analyses is an RPD of <35%. The RPD of the eight
split duplicate samples met the goal of less than 35% for all samples, as presented in Table 5.

Inter-laboratory precision was assessed by calculating the RPD between a field split sample
analyzed by two independent laboratories (AWAL and Pace). The inter- laboratory split sample
was collected at a rate of 10% of field duplicate samples, resulting in one field split soil. The data
quality objective for the inter-laboratory split sample was an RPD of 35% or less. The RPD of the
inter-laboratory split sample met the goal of less than 35% for lead and was not calculated for
arsenic because the arsenic concentration was below laboratory detection levels. The
Inter-laboratory RPD is presented in Table 6.

Duplicate samples were not collected during the supplemental Phase II sampling of the leach
field and eastern property boundary.

20201466.004A / SLC20R105847_R2 Page 23 of 27 June 2, 2020
© 2020 Kleinfelder www.kleinfelder.com
Representativeness was assessed by verifying the samples were analyzed within their analytical
method holding times and that method blanks do not report any contamination. A review of the
laboratory analytical reports indicated all sample analyses were performed within holding times
and the method blanks did not report concentrations of either lead or arsenic.

Comparability was assessed by the units of measure reported in the analytical results compared
to the units of measure established for the action levels and by using analytical methods that are
comparable to other similar studies in the same area and under the same regulatory framework.
The units of measure reported by the laboratory are the same units of measure for the action
levels and the analytical methods employed are consistent with similar studies conducted in the
area.

Percent Completeness was measured as the number of samples that were within the established
control limits for all quality control parameters. With 79 Bastian Ditch assessment samples
collected, each analyzed for total lead and arsenic, there are 158 analytical results. Of the
158 analytical results, one total arsenic and two total lead analytical results were qualified, which
represents 1.8% of the sample analyses performed. As such, 98.3% of the sample results were
not qualified and are considered valid, which exceeds the DQO of 90% valid data.

Based on our review of the analytical data and associated data quality assessment findings, we
believe that the data may be used for the intended purpose of characterizing the Site soils.

The quality of the XRF screening data was evaluated by reviewing the RPD with the associated
laboratory analytical result for total lead. The data quality objective for the XRF samples is an
RPD of <35%. The RPD results are presented on Table 1. The average RPD for the data set was
26.4%, with 75 percent of the samples meeting the RPD goal. The variation is attributed to the
non-homogenous nature of the soils as well as the relative accuracy of the field instrument.

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
as prescribed herein. Single-use, disposable sampling tools were used for sample collection, or
non-disposable sampling equipment was decontaminated between each sample location.

CONCLUSIONS AND RECOMMENDATIONS

The Site contains a portion of the Bastian Ditch, which has been designated OU5 of the Kennecott
South Zone CERCLA Site. The DERR has regulatory authority for contaminated soil management
within the Kennecott South Zone operable units, including the Bastian Ditch. Because SOJO118,
LLC wishes to redevelop, grade, and/or transport soils from OU5, DERR required a Site
characterization be conducted to assess whether elevated lead and/or arsenic concentrations
exist in the Site soils due to the presence of the Bastian Ditch. Kleinfelder conducted this Site
characterization to assess for the presence of elevated metals associated with the Bastian Ditch
and to assess other RECs identified at the Site during our Phase I ESA.

The investigation identified elevated metal concentrations in the Site soils within the Bastian Ditch
alignment at depths ranging from the ground surface to 6.5 feet bgs. Five of the ten trenches that
were sampled contained lead concentrations above the Recreational Land-Use Standard
established for the OU5 Bastian Ditch area of 2,207 mg/kg lead. Nine of the ten trenches sampled
contained lead and/or arsenic concentrations above the Unrestricted Land-Use Standards. Two
of the trenches contained RCRA-characteristically hazardous concentrations of lead. The shallow
flood plain and soil berm samples did not contain lead or arsenic concentrations above the
Unrestricted Land-Use Standards. Concentrations of lead and arsenic that exceed the
Unrestricted Land-Use Standards were also identified in nine soil samples collected from
locations along the eastern Site boundary.

Since metals concentrations were identified in the Bastian Ditch sediments that exceeded the
Unrestricted Land-Use Standards for lead and arsenic, and the proposed Site redevelopment has
the potential to expose soil with elevated concentrations of lead and arsenic, a soil removal and
management plan must be developed to properly manage metal-impacted soils that will be
disturbed during Site redevelopment. The plan will include additional characterization,
contaminant removal and disposal protocols, and post-removal soil confirmation sampling.

A heating oil UST, located east of the maintenance building, stained soil/pavement in a drum
storage area, an OWS, and a septic system and leach field were identified as potential
environmental concerns at the Site. Prior reports indicated petroleum-impacted soil was present
near the UST; however, Kleinfelder did not identify petroleum-impacted soil in the borings

20201466.004A / SLC20R105847_R2 Page 25 of 27 June 2, 2020

advanced adjacent to the UST. Petroleum impacts were also not identified near the OWS during
this investigation. Additionally, no petroleum hydrocarbons or solvent impacts were detected in
soil samples collected from the septic tank and leach field. TPH-ORO was detected in the
composite sample collected from the ground surface in the vicinity of the former drum storage
area at a concentration below the DERR ISL.

Prior to Site redevelopment, the UST must be permanently closed in accordance with DERR
regulations. It is possible that petroleum-impacted soil will be encountered beneath, or in the
vicinity of the Trans-Jordan maintenance building and associated fixtures (sumps, OWS, etc.). If
encountered, the impacted soil must be characterized and managed and/or disposed of at an
approved facility in accordance with DERR and Salt Lake County Health regulations.

Soil Characterization and Post-Removal Sampling Report Page 2-4
No soil removal was performed at this site because part of this area will be controlled
by an Environmental Covenant that will restrict excavation of soil in this area. Soil
that was excavated to expose impacted soil was placed back in the excavation in the
same order in which it was found. Soil was not removed at the location of the test pits
because the soil concentrations were not very much higher than the residential land-
use action levels and were found in relatively thin units. It is thought that should this
soil be excavated, the resulting mixing of soil units would produce soil that is under
the residential land-use action level.
2.5 Bastian Ditch Drainage Area
The Bastian Ditch Drainage site is located in the Daybreak West Village area and is
bounded on the south by 118th South Street and extends from street coordinates 6600
West to 7100 West and street coordinates 112th South to 118th south (Figure 2-4). This
site is relatively flat lying with a slight downslope to the east and has a history of
farming although it was not being actively farmed at the time of this investigation.
The area is covered with June grass vegetation and is dissected by a north-south
trending gravel road.
Kleinfelder identified four general areas where historic irrigation ditches were located
that contained lead concentrations above the residential land-use action level. These
sites were characterized to determine the lateral and vertical extent of the impacted
soil. It was found that the historic ditches did contain soil with elevated lead
concentrations but also large areas in between the ditches also contained impacted
soil. Many of the sites containing impacted soil were connected indicating that this
area may have been flood-irrigated with mining-related water and in places, the water
flowed in a sheet wash manner thereby affecting large areas. The soil containing lead
concentrations greater than 500 mg/kg was generally found to depths of 12” to 14”
below the surface however, the ditches contained soil with elevated lead up to 3.5 feet
below the surface. Locally arsenic was found in concentrations exceeding the
residential land-use action level as well.
The source of the irrigation water is known to have been the historic Bastian Ditch
that dissects the area of investigation from the northwest and flowed to the east-
southeast. This ditch carried mining impacted water from Bingham Creek located 1.5
miles to the northwest of this area. For this reason, the up-gradient end of the
historic Bastian Ditch was located in the field where it entered the Daybreak property
(not sampled in the Phase II ESA) and the soil in this area was characterized. The soil
in the vicinity of the Bastian Ditch was found to contain lead and locally arsenic above
the residential land-use action levels.

Soil Characterization and Post-Removal Sampling Report Page 2-5
The removal areas for the Bastian Ditch Drainage site covered numerous large and
small irregularly shaped areas that in total covered 12.72 acres. The removal depths
were generally between 12” to 14” below the surface although locally removal
excavations were as deep as 3.5 feet below the surface.
2.6 Transite Pipe
The transite pipe was located at two separate sites in the western Commerce Park
area (Figure 3-1). The pipe consisted of eight, 15 feet long sections of predominately
intact, non-friable asbestos transite pipe that were 15 inches in diameter. There were
a few fragments of the pipe that were on the ground next to the intact pipe sections.
Inspection of the two locations where the pipe was located indicated no other sign of
additional fragments.
The pipe was wrapped prior to removal and loaded into a truck using an all-terrain
forklift. The pipe was hauled to the Mountain View Landfill located in Salt Lake City,
Utah for disposal. Documentation of the removal of the transite pipe is included in
Appendix E.

This sample lies within an environmental covenant area. Sample 1167Z-36 represents
material between 20 and 40 inches deep and contained arsenic and lead
concentrations of 26 and 799 mg/kg, respectively. This sample lies outside of the
environmental covenant area but was left in place due to the thickness of overlying
and underlying clean soil. The lead concentrations for the remaining samples ranged
from 67 to 657 mg/kg with an average of 238 mg/kg. Arsenic concentrations ranged
from 12 to 35 mg/kg with an average of 20 mg/kg.
Bastian Ditch Drainage 9.1.7
None of the 145 post-removal samples collected exceeded the Daybreak residential or
the unrestricted land-use action levels for lead and arsenic. Lead concentrations
ranged from 26 to 498 mg/kg with an average of 208 mg/kg. Arsenic concentrations
ranged from 8 to 38 mg/kg with an average of 20 mg/kg.
None of the 61 confirmation samples collected exceeded the Daybreak residential or
the unrestricted land-use action levels for lead and arsenic. Lead concentrations
ranged from 50 to 376 mg/kg with an average of 228 mg/kg. Arsenic concentrations
ranged from 15 to 32 mg/kg with an average of 20 mg/kg.
Ten characterization samples were collected to represent soil left along the fence on
the west property line. Seven of the 10 samples exceeded the Daybreak residential
land-use action level for lead and one of the 10 samples exceeded the action level for
arsenic. Lead concentrations ranged from 273 to 2594 mg/kg with an average of 1055
mg/kg and arsenic concentrations ranged from 24 to 126 mg/kg with an average of 68
mg/kg.
Sample 1167F-2 was collected to represent the imported road base used to fill the
removal excavation across the access road. The arsenic and lead concentrations were
20 and 106 mg/kg, respectively.
9.2 SPLP
Six samples were analyzed using the SPLP. These samples were chosen because they
contained high lead and or arsenic total metal concentrations. Arsenic concentrations
found in the leachate were below the reporting limit of 0.1 mg/L for all six of the
samples. Two of the six samples contained lead concentrations above the reporting
limit of 0.05 mg/L at 0.06 and 0.19 mg/L. Leachate concentrations for each of the
RCRA 8 metals in the six samples were well below the Toxicity Characteristics (TC)
limits.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. 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.

ONE LAB. NATIONWIDE.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.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
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
The remainder of this page intentionally left blank, there are no qualifiers applied to this SDG.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. 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.

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.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. 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.

ONE LAB. NATIONWIDE.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.
RDL Reported Detection Limit.
RDL (dry)Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
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
J3 The associated batch QC was outside the established quality control range for precision.
O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate
matrix interference.
V The sample concentration is too high to evaluate accurate spike recoveries.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. 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.

ONE LAB. NATIONWIDE.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.
RDL Reported Detection Limit.
RDL (dry)Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
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
O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate
matrix interference.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. 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.

ONE LAB. NATIONWIDE.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.
RDL Reported Detection Limit.
RDL (dry)Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
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
J3 The associated batch QC was outside the established quality control range for precision.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate
matrix interference.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. 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.

ONE LAB. NATIONWIDE.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.
ND Not detected at the Reporting Limit (or MDL where applicable).
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.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
J7 Surrogate recovery cannot be used for control limit evaluation due to dilution.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. 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.

ONE LAB. NATIONWIDE.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.
ND Not detected at the Reporting Limit (or MDL where applicable).
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.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
J7 Surrogate recovery cannot be used for control limit evaluation due to dilution.
O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate
matrix interference.

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. 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.

ONE LAB. NATIONWIDE.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.
RDL Reported Detection Limit.
RDL (dry)Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
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
O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate
matrix interference.
