Brad,
The University of Utah and Terracon have prepared the attached Phase 2 Site Characterization
Report for the SLC Station Center site (DWMRC Facility ID No. UTCA-0023, formerly WRR
Industries Inc.). As noted in the report and discussed in our phone conversation yesterday with
Paige and Bill, this investigation appears to have fully delineated the groundwater impacts at the
site, but there are some soil gas impacts at the southeastern site boundary that will require off-site
sampling east of the site. We are currently working to secure access to the eastern-adjoining
property which is owned by the SLC RDA. The University will submit a separate work plan for the
eastern off-site soil gas assessment to DWMRC, pending property access approval by the RDA
and DWMRC’s approval of the remaining site characterization findings presented in this report.
Please reach out if you have any questions or comments during your review.
Thanks,

1.0 Introduction
Terracon Consultants, Inc. (Terracon) has completed a Phase 2 Site Characterization
Assessment (site investigation) at the SLC Station Center site (site) located at 550 and 570
West 400 South, Salt Lake City, Utah (Exhibit 1, Appendix A). This site investigation was
completed per the Phase 2 Site Characterization Work Plan (Phase 2 SCW; University of
Utah 2023) dated May 17, 2023. This site investigation was conducted to address data gaps
identified in the Site Characterization Report (SCR; Terracon 2023) and Phase 2 SCW, as
required to fully characterize the environmental impacts at the site and determine current
site risk levels per Utah Department of Environmental Quality (UDEQ), Division of Waste
Management and Radiation Control’s (DWMRC) requirements for risk-based closure per Utah
Administrative Code (UAC) R315-101.
1.1 Site Description
The SLC Station Center site is comprised of 1.89-acres of land currently owned by the
University of Utah and the University of Utah Research Foundation (University). The site
comprises seven parcels consisting of the addresses, Salt Lake County Assessor Parcel

Exhibit 1 presents the site location on a portion of the United States Geological Survey
(USGS) topographic map.
1.2 Site History and Summary of Previous Assessment and Corrective
Action
The site has a long history of industrial uses including automobile and heavy equipment
repair, heating plants, a paint shop, a landscaping and erosion control contractor, and other
miscellaneous industrial-type clients from the early 1900s through 2022. The site was most
recently occupied by WRR Industries, Inc., a landscaping and erosion control contractor.
The buildings on the property were used for office space and dry storage of miscellaneous
new and old stock materials such as auto parts, landscaping equipment, vehicle storage,
and diesel truck repair bays.
Terracon completed Phase I Environmental Site Assessments (ESA) at the site in 2018 and
2021 (Terracon 2018; Terracon 2021). The Phase I ESAs identified multiple Recognized
Environmental Conditions (RECs) including a long history of industrial use and the presence
of sumps, staining, oil-water separators, leaking drums, and adjacent sites with known
contamination (Quality Plating).
To evaluate conditions associated with the identified RECs, Terracon performed a Limited
Site Investigation in 2017 (LSI; Terracon 2017). The 2017 LSI involved advancement of
eight boreholes (B-1 through B-8 on Exhibit 2) to 15 feet below ground surface (bgs) to
evaluate on-site soil and groundwater impacts from the historical industrial uses of the site
and adjacent properties.
The LSI results indicated that a portion of on-site groundwater was impacted by the
presence of several dissolved-phase chlorinated volatile organic compounds (VOCs)
including tetrachloroethene (PCE), trichloroethene (TCE), cis-1,2-dichloroethene (DCE),
trans-1,2-dichloroethene (trans-1, 2 DCE), and vinyl chloride (VC). The highest
concentration of PCE was present at boring B-3 at a concentration of 34.1 mg/L which
indicated the potential presence of dense non-aqueous phase liquid (DNAPL). The source of
the contaminants was not identified, but the highest concentrations of PCE at boring B-3
were located near an oil-water separator in the northeastern portion of the site. The LSI did
not identify VOC impacts in site soils. The LSI identified de minimis petroleum impacts in
site soils and groundwater and did not identify metals impacts in site soils and groundwater
(Terracon 2017).
Additional site investigation was subsequently performed by Environmental Contractors
Incorporated (ECI) during 2018. ECI advanced seven additional soil borings in March 2018
and August 2018 (B-9 through B-15 on Exhibit 2) to further define the horizontal extent of
groundwater VOC contamination (ECI 2018). Five monitoring wells (MW-1 through MW-5 on
Exhibit 2) were subsequently installed by ECI (ECI 2020).

ECI engaged DWMRC to provide remediation oversight in September 2018. Multiple
remedial Work Plans and Corrective Action Plans were prepared by ECI and submitted to
DWMRC. The following structural demolition, soil removal, and groundwater remediation
was subsequently conducted by ECI at the site from 2018 to 2021 per the DWMRC-
approved plans (Exhibit 4).
The lean-to structure located south of the former boiler room was demolished
(ECI 2020).
The concrete floor of the former boiler room, the oil/water separator, and
associated soil to a depth of approximately 12 feet bgs were removed (ECI
2020).
A groundwater extraction trench and stacked-tray air stripper were operated in
the northeast area of the site from April 2019 through November 2019 (ECI
2020).
From March 2020 to July 2020, approximately 8,066 pounds of 97%
remediation-grade crystalline potassium permanganate (KMnO4) ~4% solution
was added to extracted groundwater and re-injected via trenches and eight soil
borings (ECI 2020).
From June 2021 to October 2021 approximately 4,630 pounds of ~4% KMnO4
solution was added to extracted groundwater and re-injected via 14 soil borings
(ECI 2022).
Structural demolition and associated soil removal conducted by ECI was conducted for
assessment purposes and not to address a specific known source area. PCE, TCE, and VC
were reported above United States Environmental Protection Agency (EPA) Maximum
Contaminant Levels (MCLs) in site groundwater during ECI’s final sampling event conducted
in September 2021 (ECI 2022) as summarized below:
PCE was reported at concentrations of 0.01 mg/L and 11.1 mg/L at MW-2 and
MW-3, respectively, which exceeded the MCL of 0.005 mg/L.
TCE was reported at a concentration of 0.0466 mg/L at MW-2, which exceeded
the MCL of 0.005 mg/L.
VC was reported at concentrations of 0.055 mg/L, 0.0162 mg/L and 0.0079
mg/L at MW-2, MW-3, and MW-4, respectively, which exceeded the MCL of
0.002 mg/L.
ECI’s September 2021 groundwater sampling results indicated that PCE concentration
rebound occurred at MW-3, suggesting incomplete remediation of the VOC plume. PCE
concentrations at MW-3 were reported at <0.001 mg/L in July 2021, increased to 18.4 mg/L
in August 2021, then declined to 11.1 mg/L in September 2021. TCE at MW-3 experienced
concentration rebound from July 2021 to August 2021, rising from <0.001 mg/L to 5.75
mg/L, and then declining to <0.001 mg/L in September 2021. VC concentrations rebounded
at MW-2, MW-3, and MW-4 in August 2021 and/or September 2021. Detectable
concentrations of additional VOC compounds were reported in MW-1, MW-2, MW-3, MW-4,

and MW-5 in September 2021 (ECI 2022). However, the VOC concentrations were below
MCLs.
Because ECI’s September 2021 groundwater sampling results exceeded DWMRC’s risk-
based closure criteria, Terracon subsequently conducted groundwater sampling, soil gas
sampling, and a high-resolution site characterization survey (HRSC survey) in January and
February 2023. Terracon’s January–February 2023 investigation documented ongoing VOC
impacts in groundwater in the existing monitoring wells, VOC impacts in soil gas, and a
potential extension of the chlorinated solvent plume in groundwater on the northern portion
of the site. The January–February 2023 investigation is detailed in the SCR (Terracon 2023).
Terracon’s January–February 2023 investigation concluded that the nature and extent of
VOC contamination in soil, groundwater, and soil gas at the site had not been fully
characterized and defined and that the chlorinated solvent occurrences exceeded UAC R315-
101 criteria for risk-based closure. Additional sampling of soil, groundwater, and soil gas
was conducted in August–September 2023 to attempt to fully characterize the nature and
extent of chlorinated solvent impacts at the site. This report provides a comprehensive
summary of the results of Terracon’s January–February 2023 and August–September 2023
sampling events.
2.0 Site Characterization Scope and Methods
The following sections detail the scope and methods of the site characterization sampling
that was conducted by Terracon in January–February 2023 and August 2023 to investigate
the data gaps identified in the Phase 2 SCW.

2.3 Sampling Methods
2.3.1 Utility Clearance and Drilling Activities
The public utility location service (Blue Stakes of Utah) was notified at least 48 hours prior
to commencing drilling activities. A private utility location service was used to locate
potential utilities and other subsurface obstacles in the immediate vicinity of each boring
location.
Monitoring well and soil gas probe installation services were performed by Utah-licensed
well driller Direct Push Services. Terracon environmental personnel directed and supervised
the monitoring well and soil gas probe installation.

2.3.2 Monitoring Well Installation and Soil Sampling
Thirteen new permanent groundwater monitoring wells were installed (Exhibit 2)to
intercept critical areas of the apparent VOC plume identified by the original HRSC survey
(Terracon 2023) and to confirm the boundaries of the VOC plume modeled by the original
HRSC survey. One monitoring well was also installed on public property south of the site to
evaluate potential off-site migration of the groundwater VOC plume. Monitoring wells were
not installed on adjacent private property. Monitoring wells were installed per the
procedures detailed in Terracon Standard Operating Procedure (SOP) 10B,Monitoring Well
Design and Installation (using direct-push drilling).
Monitoring wells were constructed with 2-inch diameter polyvinyl chloride (PVC) casing, with
0.010-inch factory-slotted well screen from the bottom of the well and solid casing from the
top of the screen to the land surface. A 10/20 graded silica sand filter pack was placed from
the bottom of the well to approximately two feet above the top of well screen, followed by a
hydrated bentonite chip annular seal to approximately 1-foot bgs. The monitoring wells
were fitted with locking J-plug well cap and a flush-mount, traffic-rated well box.
Following monitoring well installation, the static groundwater level in each well was
measured to the nearest 0.01-foot at the top of the well casing to assess if adequate
groundwater was present for development. The monitoring wells were developed utilizing a
polyethylene weighted bailer until a minimum of three to five well casing volumes of
groundwater had been removed, or the monitoring wells had been purged dry. After
development, the monitoring wells were allowed to reach equilibrium for a minimum of 24-
hours prior to groundwater sample collection.
Soil samples were collected from direct-push borings concurrently with monitoring well
installation (Table C3) to document lithology and collect samples for laboratory analysis of
soil VOCs at the depth intervals specified in the Phase 2 SCW.
During advancement of the borings, soils were logged as detailed in Terracon SOP 1,Soil
Sampling and Logging. Soil samples were collected following the procedures detailed in
Terracon SOP 5,Geoprobe Sampling. Soil samples were field screened using sensory
methods and with a Photoionization Detector (PID) equipped with a 10.6 electron volt
ultraviolet lamp source to evaluate the presence of VOCs (Appendix C).
2.3.3 Groundwater Sampling
Groundwater samples were collected from the monitoring wells using low-flow sampling
methods following the procedures detailed in Terracon SOP 12,Groundwater Monitoring
Well Sampling. Groundwater samples were dispensed directly into laboratory-supplied
sample containers and analyzed for VOCs via EPA Method 8260B.
Prior to sampling, Terracon personnel measured the static groundwater level in each well to
the nearest 0.01-foot at the top of the well casing. Terracon personnel surveyed the
Phase 2 Site Characterization Report

Facilities |Environmental | Geotechnical | Materials 8
monitoring well top-of-casing elevations to determine the groundwater flow direction and
develop a groundwater surface elevation map for the eastern portion of the site and off-site
to the south (Exhibit 5).
2.3.4 Soil Gas Sampling
Soil gas samples were installed and collected following the procedures detailed in Terracon
SOP 9,Soil-gas/Vacuum Probe Installation, and Terracon SOP 9A,Soil Gas Sampling. Soil
gas sampling was conducted by using a direct-push drill rig to advance borings to an
approximate depth of 5 feet bgs followed by the installation of soil gas probes. The probes
consisted of a 6-inch long stainless steel disposable screen anchored to polyethylene tubing
that extends to the surface. A one-foot, 10–20 silica sand pack was placed around the probe
and the remainder of the anulus was filled with hydrated bentonite chips. Care was taken to
ensure adequate hydration of the chips to avoid air flow through the bentonite. Due to
interior drill rig access limitations, a sub-slab Vapor Pin® was installed in lieu of a soil gas
probe at one soil gas sampling location (sample location SV-4,Exhibit 3)
The soil gas probes were allowed to equilibrate for a minimum of 24 hours prior to
sampling. Prior to sample collection, Terracon conducted leak detection tests at each sample
location. The first test evaluated the sample train for leaks by conducting a shut-in test on
the sample train after it was fully assembled. The shut-in test was conducted by closing the
valve to the gas probe and applying a vacuum to the closed sample train while monitoring
the pressure on an inline vacuum gauge for one minute. If the sample train held a constant
vacuum pressure, the sample train was deemed to be airtight. Following the shut-in test,
the air that was evacuated from the sample train to generate the vacuum was purged.
A second leak detection test was conducted by introducing helium gas at a concentration
between 15 and 20 percent into a sampling shroud placed over the probe. If helium is
measured in the sampling train at a concentration of greater than 7,500 parts per million
(ppm) it will indicate there was potential breakthrough in the sampling train and all
connections will be re-examined and tightened where necessary and re-tested.
The soil gas samples were collected in laboratory-supplied, batch-certified clean 1,000 mL
Summa® canisters, using new Teflon® tubing and a flow regulator that restricted flow to no
more than 200 mL per minute. Soil gas samples were analyzed for VOCs via EPA Method
TO-15. Following the collection of the samples, the soil gas probes were left in place to allow
for additional sample collection in the future, if necessary.
2.3.5 High Resolution Site Characterization Survey
A HRSC survey was performed using MIHPT technology to assess the horizontal and vertical
occurrence of VOC contamination in soil and groundwater and identify possible ongoing
source areas (i.e., sorbed-phase or residual DNAPL). A team of HRSC specialists, direct-
Phase 2 Site Characterization Report

October 3, 2023 | Terracon Project No. 61217142
Facilities |Environmental | Geotechnical | Materials 9
push drilling rig, and a command center vehicle housing all applicable technologies and
equipment were deployed to perform the HRSC survey at the site.
The MIHPT probe is a logging tool that indicates volatile hydrocarbon and solvent
contamination, soil electrical conductance, and hydraulic indicators of formation
permeability. An inert carrier gas is continually swept behind a heated membrane in the
probe, delivering diffused VOCs to a series of detectors in the command center vehicle. The
detectors each respond to different analyte properties, which allows for differentiation of
contaminants (i.e., volatile petroleum hydrocarbons or chlorinated solvents) and provides
the ability to map out the contaminant plume from source to extent. The MIHPT system
features multiple membrane interface detectors, sensors, and tools to assess subsurface
characteristics and VOC occurrence, including:
Electrical Conductivity (EC) sensor: The EC sensor creates a log of EC versus depth.
The EC of soil varies with soil grain size and a correlation can be made to soil type
relative to the EC. Broadly, sandy soils correlate to lower EC values, and EC
increases as soil grain size decreases to silt and clay-sized particles.
Hydraulic Profiling Tool (HPT): The HPT creates a log of the relative formation
permeability versus depth by injecting clean water at a constant flow rate through
the direct push rods and into adjacent soil via an injection port on the side of the
probe. Sensors record the flow rate and back pressure which are used to estimate
hydraulic conductivity relative to depth. The hydraulic conductivity values estimated
by the HPT are useful in understanding zones within the subsurface exhibiting higher
or lower relative permeabilities. Understanding soil permeability can aid in the
understanding of contaminant transport, storage, and flux.
Photoionization Detector: The PID responds to VOCs (i.e., petroleum hydrocarbons
and chlorinated solvents) and creates a log versus depth. Response is measured in
microvolts (µV) and can be used as a semi-quantitative method to compare VOC
intensity along both the vertical profile of an individual boring and relative to other
boring locations.
Flame Ionization Detector (FID): The FID responds to combustible VOCs only (i.e.,
petroleum hydrocarbons). Response is measured in µV and can be used as a semi-
quantitative method to compare petroleum hydrocarbon intensity along both the
vertical profile of an individual boring and relative to other boring locations.
Halogen Specific Detector (XSD): The XSD responds only to halogenated compounds
(i.e., chlorinated solvents). This detector creates a log of halogenated response
versus depth. Response is measured in µV and can be used as a semi-quantitative
method to compare halogenated compound intensity along both the vertical profile
of an individual boring and relative to separate boring locations.

This VOC contamination, lithology, and hydraulic conductivity data was captured every inch
the tooling was advanced and utilized in real time by field personnel to determine the next
boring locations.
Sixteen MIHPT borings were advanced during February 2023 and five additional MIHPT
borings were advanced in August 2023 (Exhibit 11) to depths ranging from 33 feet bgs to
53 feet bgs. A daily HRSC field report was generated by the contractor for review by
Terracon. This report included all preliminary data, boring locations completed, and quality
control results. Electronic data files were also transmitted to Terracon daily for data
management purposes and to optimize subsequent testing locations (Appendix D).
2.3.6 Field QA/QC Samples
Field duplicates were collected at a rate of 10 percent with one trip blank (laboratory-
supplied blank) per sample shipment. Five duplicate groundwater VOC samples and two
duplicate soil VOC samples were collected. Field duplicate samples and trip blanks are not
applicable to soil gas sampling and were not collected.

2.3.7 Equipment Decontamination
Clean disposable, single-use sampling equipment was used to conduct the soil,
groundwater, and soil gas sampling and was properly disposed of after each use. Drilling
equipment was cleaned using a high-pressure washer prior to beginning the project and
between soil gas probe locations.
MIPHT equipment was decontaminated using a three-bucket approach once all rods and the
probe were removed from each borehole. Wet rods were rinsed, washed with Alconox, then
rinsed again.
2.3.8 Site Restoration
Monitoring wells were completed with a flush-mount, traffic-rated well box. MIPHT borings
were backfilled with granular bentonite and hydrated with culinary water. Soil gas probes
were left in place to allow for additional future sampling, if needed.

3.4 HRSC Survey Data Summary
A HRSC survey was performed at the site which consisted of advancing twenty-one MIHPT
borings throughout exterior areas of the eastern portion site (Exhibit 11).The XSD
responses results suggested that a large and previously undocumented extension of the
chlorinated solvent plume was present in groundwater on the northern portion of the site,
extending to depths of at least 45 feet bgs in apparent silt and silty clay soils (Terracon
2023). Calibration checks, that were performed throughout the HRSC survey using known
standards, suggested that the highest XSD responses correlated to total chlorinated solvent
concentrations between 5 mg/L and 10 mg/L. However, laboratory analytical samples
collected from new monitoring wells installed on the northern portion of the site did not
support the HRSC survey results (Section 3.1;Table C1).
Detector responses that could suggest the presence of petroleum contamination (i.e.,
correlated PID and FID responses) were observed in MIHPT borings MIP-20 and MIP-21, but
a corresponding laboratory soil sample collected from MIP-20 reported concentrations of
petroleum hydrocarbons that were below UDEQ screening levels (Table C3). A copy of the
HRSC survey report is provided in Appendix D.
4.0 Data Quality Assessment
Laboratory analytical data was subject to internal reduction and validation prior to external
release of the data, as detailed in the laboratory’s Quality Assurance Manual. Following
receipt of the laboratory analytical results by Terracon, the data were reviewed to evaluate
compliance with Data Quality Indicators (DQIs).
Documentation provided with the laboratory analytical results reports included case
narratives; analytical data with minimum method detection limits (MDLs) and reported
detection limits (RDLs) reporting limits listed for all analyses; surrogate recoveries for gas
chromatography/mass spectroscopy (GC/MS) analyses with laboratory control limits; chain-
of-custody records; and a quality control summary including method blanks, matrix
spike/matrix spike duplicates (MS/MSD) with control limits, laboratory control samples and
duplicates (LCS/LCSD) with control limits; and application of data qualifiers where
warranted.
Assessment of the DQIs for Precision, Bias and Accuracy, Representativeness,
Comparability, Completeness, and Sensitivity are presented in the following subsections.

4.1 Precision
Precision was evaluated on the basis of relative percent difference (RPD) as a measure of
reproducibility between LCS/LCSD pairs and MS/MSD pairs (analytical precision) and
between field samples and field duplicate samples (field precision).
The RPD is calculated to evaluate precision using the following equation.
RPD=𝑿𝟎−𝑿𝟎
ቀ𝑿𝟎+𝑿𝟎
𝟎ቁ
𝒙𝟎𝟎𝟎Where X1 and X2 are the reported concentrations of the
samples being evaluated.
4.1.1 Analytical Precision
A summary of the Quality Control assessment for analytical precision is presented below.
Laboratory Sets L1576151, L1577035, L1647891, and L1652509
(Groundwater Samples):
o The RPDs for the MSD (Laboratory Batch WG2117810) associated with 1,3,5-
trimethylbenzene and 2-chloroethyl vinyl either and the MSD associated with
trichloroethene (Batch WG2127237) were outside the laboratory’s control
limits. Additionally, the RPDs for the LCSD (Batch WG2117684) for 1,1,2-
trichlorotrifluoroethane and bromomethane and the LCSD associated with
acrolein and acrylonitrile (Batch WG2117810) were outside the laboratory’s
control limits. As a result, a J3 flag was used to qualify this data. The affected
samples were all non-detect for these analytes with the exception of
trichloroethene where several samples had detections well above regulatory
screening levels. Additionally, other DQIs were in control. It is not anticipated
the analytical precision issue will affect the conclusions of this report, and it is
assumed that the concentrations of trichloroethene are above regulatory
screening levels for the affected samples where applicable.
Laboratory Sets L1577012 and L1648039 (Soil Gas Samples):
o The RPDs for the LCS/LCSD pairs were within the laboratory control limits. A
MS/MSD sample was not analyzed from this data set.
Laboratory Sets L1649038, L1647890, and L1645715 (Soil Samples):
o The RPDs for the LCSD (Laboratory Batch WG2114638) associated with
naphthalene, the LCSD associated with acetone and acrylonitrile (Batch
WG2118179), and the LCSD associated with hexachloro-1,3-butadiene (Batch
WG2119146) were outside the laboratory’s control limits. As a result, a J3
flag was used to qualify this data. The affected samples were all non-detect
for these analytes. The affected naphthalene sample was the trip blank, and
naphthalene was not detected above laboratory reporting limits. Additionally,
Phase 2 Site Characterization Report

October 3, 2023 | Terracon Project No. 61217142
Facilities |Environmental | Geotechnical | Materials 18
other DQIs were in control. A MS/MSD sample was not analyzed from these
data sets.
Based on the results of the RPD analyses of the LCS/LCSD samples and the evaluation
provided above,analytical precision is considered within control for Laboratory Sets
L1576151, L1577035, L1577012, L1649038, L1647890, L1645715, L1647891, L1652509,
and L1648039. Although MS/MSD samples were not analyzed for some of these data sets,
other DQIs were within control. This is not anticipated to affect the usability of this data or
the conclusions of this report.
4.1.2 Field Precision
Five field duplicate groundwater samples and two field duplicate soil samples were collected
and analyzed. Collection of field duplicates does not apply to soil gas sampling. A summary
of the Quality Control assessment for field precision is presented below.
Analytical results for original samples and field duplicate pairs that are less than five times
the laboratory’s RDL in the analytical reports were considered within control if the difference
between the sample concentration and its duplicate was less than two times the RDL. When
analytical results for the original sample and the field duplicate pairs are greater than five
times the RDL the duplicate pair was considered within control when the RPDs for the field
duplicate pairs were within 25% for groundwater samples and 50% for soil samples.
Laboratory Sets L1576151, L1577035, L1647891, and L1652509 (Groundwater
Samples): Five duplicate groundwater sample pairs were run for VOCs. The duplicate
pairs are considered within control as all the analytes achieved the requirements listed
above with the exception of cis-1,2-dichloroethene and trichloroethene. For these
analytes, the original result was greater than 5 X RDL and the duplicate was less than 5
X RDL where the difference was slightly greater than the RDL (Table C9.1). These
analytes are considered not in control. The same analytes were within control for the
remaining duplicate pairs, and several samples had concentrations of these analytes
above regulatory screening levels. As a result, this is not expected to affect the usability
of this data or the conclusions of this report.
Laboratory Sets L1649038, L1647890, and L1645715 (Soil Samples): Two
duplicate soil sample pairs were run for VOCs. The duplicate pairs are considered within
control as all the analytes achieved the requirements listed above (Table C9.2).
Based on the results of the RPD analyses of the field duplicate sample pairs and the
evaluation provided above,field precision is considered within control for Laboratory
Sets L1576151, L1577035, L1647891, L1652509, L1649038, L1647890, and L1645715.

4.2 Bias and Accuracy
Bias and Accuracy were evaluated through a review of the method blanks, trip blanks,
percent recoveries for LCS/LCSD, and percent recoveries for MS/MSD summaries provided
by the laboratory. Method blanks and trip blanks were considered within control (i.e.,
accuracy) if the constituents analyzed were less than the analytical method reporting limits.
LCS/LCSD and MS/MSD analyses were considered within control if the percent recoveries
were within the laboratory’s established limits (i.e.,bias). A summary of the Quality Control
assessment for Bias and Accuracy is presented below.
Laboratory Sets L1576151, L1577035, L1647891, and L1652509
(Groundwater Samples):
o Accuracy—Method Blank: All analytes in the method blanks were less than
the laboratory RDLs.
o Accuracy—Trip Blank: All analytes in the trip blank were less than the
laboratory RDLs.
o Surrogate Recoveries:Surrogate recoveries were within control.
o Bias—LCS/LCSD Percent Recoveries:The LCS and LCSD for
chloromethane (Batch WG1989060) and the LCSD for tetrachloroethene
(Batch WG1990087) were above the established quality control range for
accuracy. A J4 value was assigned to this data. Results for chloromethane in
the affected samples were not detected above RDLs or applicable screening
levels despite this high bias, and chloromethane is not considered a
contaminant of concern at the site. Multiple samples exceeded regulatory
screening levels for tetrachloroethene. They are considered to exceed these
levels despite the high bias. As a result, the percent recoveries for these
analytes being outside of the laboratory’s control limits is not anticipated to
affect the usability of the data.
The LCS and LCSD for 1,3,5-trimethylbenzene and naphthalene (Batch
WG2117810) was below the established quality control range. Additionally,
the LCS for methylene chloride (Batch WG2117810) was above the
established quality control range for accuracy. A J4 value was assigned to this
data. The affected samples were non-detect for these analytes, and these
analytes are not considered a contaminant of concern at the site. This is not
expected to affect the usability of the data.
o Bias—MS/MSD Percent Recoveries:The MS for 1,2-dichloroethane,
tetrachloroethene, trichloroethene, and trichlorofluoromethane (Batch
WG2127237) interfered with the ability to make any accurate determination,
causing a high spike value. A J5 qualifier was applied to this data. The

affected sample was non-detect for these analytes. This is not expected to
affect the usability of the data.
The MS and MSD for 1,1,2-trichlorotrifluoroethane, benzene, and
trichlorofluoromethane (Batch WG2117810) interfered with the ability to
make any accurate determination, causing a high spike value. A J5 qualifier
was applied to this data. The affected samples were either non-detect or
detected well below regulatory screening levels (benzene). This is not
expected to affect the usability of the data.
The MS for 2-chloroethyl vinyl ether (Batch WG2127237) interfered with the
ability to make any accurate determination, causing a low spike value. A J6
qualifier was applied to this data. The affected sample was non-detect for this
analyte, which is not a contaminant of concern at the site. This is not
expected to affect the usability of the data.
The MS and MSD for 1,2,3-trimethylbenzene and 2-chloroethyl vinyl ether
(Batch WG2117810) interfered with the ability to make any accurate
determination, causing a low spike value. A J6 qualifier was applied to this
data. The affected sample was non-detect for these analytes which are not
contaminants of concern at the site. This is not expected to affect the
usability of the data.
Laboratory Sets L1577012 and L1648039 (Soil Gas Samples):
o Accuracy—Method Blank: Ethanol was detected at an estimated
concentration (J value) in the Method Blank for Batch WG2117583. This is not
expected to affect the usability of this data.
o Accuracy—Trip Blank: A trip blank was not submitted for the soil gas
analysis.
o Surrogate Recoveries:The laboratory noted that surrogate recovery limits
for one surrogate (1,4-bromofluorobenzene, Batch WG2117583) in Laboratory
Report L1648039 (soil gas) were exceeded resulting in a J1 flag. Other
surrogates were in control as were other DQIs. This is not expected to affect
the usability of the data.
o Bias—LCS/LCSD Percent Recoveries:The percent recoveries in the
LCS/LCSD were within the laboratory’s control limits.
o Bias—MS/MSD Percent Recoveries:A MS/MSD sample was not analyzed
for this data set.

screening levels for tetrachloroethene. They are considered to exceed these
levels despite the high bias. As a result, the percent recoveries for these
analytes being outside of the laboratory’s control limits is not anticipated to
affect the usability of the data.
The LCS for naphthalene (Batch WG2114638) was below the established
quality control range for accuracy. The LCS for tetrachloroethene (Batch
WG2116333) was above the established quality control range for accuracy. A
J4 value was assigned to this data. The affected naphthalene sample was the
trip blank, and this analyte was not detected above laboratory reporting
limits. The affected tetrachloroethene results were non-detect for the affected
samples.
The LCS for tert-butylbenzene (Batch WG2119146) was below the established
quality control range for accuracy. A J4 value was assigned to this data. The
affected tert-butylbenzene results were non-detect for the affected samples.
o Bias—MS/MSD Percent Recoveries:A MS/MSD sample was not analyzed
for these data sets.
Bias and Accuracy are considered within control for Laboratory Sets L1576151,

L1648039. Some minor exceptions exist but are not expected to have an impact on the
usability of the results. Although MS/MSD samples were not analyzed for some of these data
sets, other DQIs were within control. This is not anticipated to affect the usability of this
data or the conclusions of this report.

4.3 Representativeness
Representativeness is a qualitative parameter most concerned with proper design and
execution of the sampling program to produce data that accurately and precisely represent
environmental conditions. Selection of analytical methods, sampling methods, and locations
representative of the media sampled were set forth in the Phase 2 SCW.
Representativeness in the field was achieved by implementing the approved Phase 2 SCW
and using appropriate sampling methods, sample containers, sample handling, and
preservation methods.Representativeness in the laboratory was achieved by using the
proper analytical procedures, meeting sample holding times, and analyzing and assessing
laboratory Quality Assurance/Quality Control (QA/QC) samples.
Field Representativeness
Sampling was conducted in general accordance with the Phase 2 SCW and associated SOPs.
The following deviations from the Phase 2 SCW occurred during the sampling events.
Additional soil samples were collected from sample locations MW-14 and MIP-20
based on field PID readings.
A few MIPHT borings and monitoring wells were moved slightly to accommodate drill
rig access or avoid identified utilities. It is unlikely that small changes in the
locations of these borings had a significant effect on data quality.
Laboratory Representativeness
Sample analyses followed the analytical methods listed in the Phase 2 SCW or equivalent
EPA-approved variations of the listed methods.
Sample analyses followed the analytical methods listed in the Phase 2 SCW or
equivalent EPA-approved methods or variations of the listed methods; and were
analyzed within method-specified holding times.
The analyte concentration for 2-propanol in soil gas sample SV-1 (Batch
WG1992097) exceeded the upper limit of the calibration range of the instrument
established by the initial calibration (ICAL). The fact that the calibration failed, 2-
proponal was detected at least three orders of magnitude higher in this sample than
any other sample collected from the site, and that 2-propanol is not considered a
contaminant of concern at the site based on historical use of the site indicates that
this data should be rejected. This is not expected to affect the usability of the
remaining data or conclusions of this report.
The laboratory noted that the analyte concentration for acetone and 2-propanol
(Batch WG2117583) in Laboratory Report L1648039 (soil gas) exceeded the upper
limit of the calibration range of the instrument established by the ICAL. These

analytes were detected in the affected samples at concentrations at least an order of
magnitude below regulatory screening levels and they are not considered
contaminants of concern at the site. This is not expected to affect the usability of
the data.
The laboratory noted that the pH was outside of the method requirement for
Batches WG2119158 and WG2121192. The sample containers were supplied from
the laboratory and were already preserved. This is not expected to affect the
usability of the data.
Representativeness is considered within control.
4.4 Comparability
Comparability is a qualitative term expressing the confidence with which one data set can
be compared to another. The comparability goal was achieved using standardized sampling
procedures in accordance with the Phase 2 SCW, use of standardized and approved
laboratory analytical methods, and reporting the analytical results in appropriate and
consistent units.
Sampling was conducted in general accordance with the Phase 2 SCW and
associated SOPs. Deviations from the Phase 2 SCW occurred during the sampling
event and are discussed in Section 4.3.
Sample analyses followed the analytical methods listed in the Phase 2 SCW,
equivalent approved methods, or variations of the listed methods.
The units of measure reported by the laboratory were consistent with the units of
measure used by the regulatory screening levels.
The number of field duplicates specified in the approved Phase 2 SCW was at
least 10% of the field samples.
o Groundwater Samples
VOCs: Five groundwater field duplicates for thirty-four groundwater
samples or 14.7%, which exceeds the 10% goal.
o Soil Samples
VOCs: Two soil field duplicates for seventeen soil samples or 11.7%,
which exceeds the 10% goal.
Comparability is considered within control.
4.5 Completeness
Completeness is the ratio of valid measurements to the number of planned measurements,
expressed as a percentage, and the completeness goal for the project is 90%. The sampling
program is deemed to meet the DQIs for valid measurements. The samples collected were
Phase 2 Site Characterization Report
SLC Station Center | Salt Lake City, Utah
October 3, 2023 | Terracon Project No. 61217142
Facilities |Environmental | Geotechnical | Materials 24
submitted and analyzed by the laboratory according to the chain-of-custody. Additionally,
the data collection followed the procedures and requirements as described in the approved
work plans. The data are considered usable as qualified. The analytical completeness for this
sampling event was >100%. Although one analyte (2-proponal) for one soil gas sample
(SV-1) was rejected, the sample completeness was well above the 90% threshold.
With acknowledgement of qualified results for the analytes listed above, the
analytical data are acceptable for their intended use to evaluate constituent
concentrations compared to applicable regulatory screening levels.
4.6 Sensitivity
Sensitivity refers to the capability of a method or instrument to discriminate between
measurement responses representing different levels of the variable of interest. The
sensitivity goal is for RDLs to be below comparative screening levels, which vary
considerably by analyte and in value and applicability. Overall, the level of sensitivity was
sufficient to allow the identification of soil, groundwater, and soil gas constituents above
applicable regulatory screening levels.
Laboratory Sets L1576151, L1577035, L1647891, and L1652509
(Groundwater Samples):
o VOCs: The RDLs were all less than the EPA VISLs and MCLs, as applicable, for
analytes reported as less than the RDL. The only exceptions to this were
acrolein, acrylonitrile, bromodichloromethane, carbon tetrachloride,
chloroform, 1,2-dibromo-3-chloropropane, 1,2-dibromoethane, hexachloro-
1,3-butadiene, and naphthalene which exceeded at least one of these
screening levels in at least one sample. None of these groundwater samples
had detections of these analytes or are considered contaminants of concern at
the site. Hence, this sensitivity issue for groundwater samples is not
anticipated to affect the conclusions of this report.
Laboratory Set L1577012 and L1648039 (Soil Gas Samples):
o The RDLs were all less than the EPA VISLs, as applicable, for analytes
reported as less than the RDL. The only exceptions to this were 1,3-
butadiene, 1,2-dibromoethane, hexachloro-1,3-butadiene, and naphthalene.
None of these soil gas samples had detections of these analytes or are
considered contaminants of concern at the site. Hence, this sensitivity issue
for soil gas samples is not anticipated to affect the conclusions of this report.
Laboratory Sets L1649038, L1647890, and L1645715 (Soil Samples):
o The RDLs were all less than the EPA RSLs, as applicable, for analytes reported
as less than the RDL. The only exceptions to this were 1,2-dibromo-3-

chloropropane, 1,2-dibromoethane, and 1,2,3-trichloropropane. None of these
soil samples had detections of these analytes or are considered contaminants
of concern at the site. Hence, this sensitivity issue for soil samples is not
anticipated to affect the conclusions of this report.
The DQIs for Sensitivity were achieved. As such,Sensitivity was deemed acceptable.
5.0 Updated Conceptual Site Model
This update to the conceptual site model (CSM) refines the CSM that was presented in the
SCR (Terracon 2023) and presents the current understanding of the release based on the
physicochemical properties of the contaminants of concern in combination with the most
recently collected site-specific data. The goals of the updated CSM are to:
Identify the contaminants of concern, their relative subsurface distribution, and
related environmental concerns associated with the release.
Define the remedial goals associated with the environmental concerns.
Identify informational data gaps and appropriate next steps.
The subsections identified below are core components to the updated CSM.
5.1 Geologic and Hydrogeologic Information and Setting
Near-surface soils consist of sandy gravel fill material to a depth of approximately 1 to 3.5
feet bgs. Up to 25 feet bgs, the fill materials are underlain by native silt, silty clay, and clay
that is occasionally interbedded with silty sand and poorly-graded sand layers (Appendix C).
From 25 feet bgs to 50 feet bgs clays and silty clays predominate (Appendix C).
Groundwater is present at depths of approximately 8–9 feet bgs in the monitoring wells.
Groundwater flow is in a generally westerly direction (Exhibit 5).
Surficial geologic units are underlain by sediments deposited within Lake Bonneville which
range from sand and gravel to silt and clay. The silts and clays generally represent
sediments deposited during deep water conditions away from canyon mouths and the
mountain front, while lake-deposited sand and gravel generally represent near-shore
sediments and deltaic deposits near canyon mouths (UGS 2009). Fine-grained silt and clay
deposits are expected to occur below surficial deposits at the site as the nearest canyon
mouth/mountain front depositional area is located approximately two miles to the northeast
at the mouth of City Creek Canyon.
Alluvial and lacustrine sediments of considerable thickness underlie the Lake Bonneville
deposits. Estimates of the total thickness of unconsolidated Quaternary deposits in the Salt
Lake Valley range from approximately 130 feet to as much as 2,000 feet (Wong et al.
Phase 2 Site Characterization Report
SLC Station Center | Salt Lake City, Utah
October 3, 2023 | Terracon Project No. 61217142

2002), depending on the proximity to the deepest part of the basin. Below this, semi-
consolidated and consolidated sediments extend to a depth of up to 8,500 feet, below which
bedrock is found (Wong et al. 2002).
The basin-fill aquifer system in the Salt Lake Valley includes a confined aquifer in the central
and northern parts of the basin (where the site is located), a deep unconfined aquifer
between the confined aquifer and the mountains, and a shallow unconfined aquifer overlying
the artesian confined aquifer (UGS 2009). The confining layer is between 40 and 100 feet
thick, and the top of the layer is between 50 and 150 feet below the land surface (UGS
2009). The shallow unconfined aquifer overlies the confining layer and is composed
primarily of fine-grained sediments that are only slightly more permeable than the confining
layer; in some areas it is difficult to differentiate between the two (UGS 2009). The shallow
unconfined aquifer yields little water, and the water is generally of low quality (UGS 2009).
5.2 Chlorinated Solvent Properties and Phased Spatial Distribution
5.2.1 Chlorinated Solvent Physical and Chemical Properties
PCE is a chlorinated ethene that is currently and has historically been used as a solvent in
dry cleaning, textile processing, and metal cleaning operations. Under ambient conditions
PCE will readily evaporate and generate PCE vapor. PCE is identified to be a probable human
carcinogen and short-term exposure to high concentrations may affect the central nervous
system. PCE has a density of 1.622 grams per cubic centimeter (g/cm3), which is greater
than the density of water, indicating immiscible PCE will ‘sink’ below the groundwater
surface and is classified as a DNAPL.
PCE has a chemical formula of C2Cl4 and consists of double bonded carbon atoms saturated
with chlorines. Pure PCE released into the subsurface can exist in four distinct phases that
present unique risks to receptors: pure-phase (i.e., DNAPL), sorbed-phase, dissolved-phase,
and vapor-phase.
In the dissolved phase, the sequential replacement of chlorine atoms with hydrogen atoms
may occur under natural groundwater conditions and results in the formation of breakdown
products that themselves are environmental contaminants of concern and include TCE
(C2HCl3), DCE (C2H2Cl2), and VC (C2H3Cl). In the subsurface, PCE and related breakdown
products are considered recalcitrant contaminants because of their density, mobility in the
aqueous phase, high toxicity, and general lack of omnipresent natural degraders.
5.2.2 Sorbed-Phase Contaminants of Concern and Spatial Distribution
Source area identification and an understanding of contaminant migration through the
subsurface and into the water-bearing zone are critical components of the CSM as sorbed-
phase or residual DNAPL and may result in persistent sources of dissolved-phase and vapor-
phase impacts. The investigations conducted to date by Terracon and ECI have collected soil
Phase 2 Site Characterization Report
SLC Station Center | Salt Lake City, Utah
October 3, 2023 | Terracon Project No. 61217142
Facilities |Environmental | Geotechnical | Materials 27
samples from over 30 locations throughout the site and have not reported chlorinated
solvent impacts in soil above applicable screening levels. It is considered unlikely that
additional characterization would identify a source of sorbed-phase contamination in an area
that has not been previously sampled.
5.2.3 Dissolved-Phase Chemicals of Concern and Spatial Distribution
Seventeen on-site monitoring wells and one off-site monitoring well are currently present.
Five of the on-site wells previously existed, and twelve on-site wells and one off-site well
were installed in early August 2023 for current investigation (Exhibit 2). Groundwater
samples have also historically been collected from an additional fifteen soil boring locations
(Exhibit 2). The monitoring wells have depths ranging from 17 feet bgs to 50 feet bgs
(Appendix C).
Monitoring well and historical soil boring data indicate the following regarding the
distribution of dissolved-phase chlorinated solvent impacts:
Maximum dissolved-phase chlorinated solvent impacts are currently present at and
in the vicinity of MW-1, MW-2, and MW-8 (Exhibit 6 through Exhibit 8)
The lateral extents of PCE impacts appear to be well defined to the north, south,
east, and west.
The lateral extents of TCE impacts appear to be defined to the north, south, and
west, and largely defined to the east. Low concentrations of TCE are present on the
eastern site boundary at MW-9 (Exhibit 7). Because the apparent groundwater flow
direction is east-to-west, it is considered unlikely that the TCE impacts extend a
meaningful distance east of MW-9.
The lateral extents of DCE impacts appear to be defined to the north, south, east,
and west, albeit with some conflicting results between the mid-August and late-
August/early-September groundwater sampling events. The mid-August sampling
results indicated the presence of DCE impacts on the eastern site boundary at MW-9
and off-site to the south at MW-15, but the late-August/early-September sampling
results did not (Table C1). The mid-August sampling event was conducted
immediately following installation and development of the new monitoring wells.
Because of the disturbance associated with the well installation, the late-
August/early-September sample results are considered more reliable indicators of
actual groundwater conditions. Concentrations of all chlorinated solvent compounds
were consistently lower at all newly-installed monitoring wells (MW-6 through MW-
15) during the late-August/early-September sampling event compared to the mid-
August sampling event.
The lateral extents of VC impacts appear to be defined to the north and east, but
not fully defined to the south and west. To the west, VC concentrations at MW-5 are
minimally elevated above the EPA MCL and EPA Commercial TGC VISL, indicating
Phase 2 Site Characterization Report
SLC Station Center | Salt Lake City, Utah
October 3, 2023 | Terracon Project No. 61217142
Facilities |Environmental | Geotechnical | Materials 28
that VC impacts are unlikely to extend off-site given the distance to the western site
boundary (approximately 100 feet). The southern-adjacent property is occupied by
Quality Plating, which has been used for chrome plating and other industrial
purposes since the 1950s. The Quality Plating property is considered a poor location
for further delineation given the potential for chlorinated solvent impacts unrelated
to the SLC Station Center site, and the lack of PCE, TCE, and DCE impacts at MW-
15.
The vertical extent of dissolved-phase chlorinated solvent impacts appears to be
limited to a depth of less than 25 to 30 feet bgs. Subsurface lithology below this
depth is dominated by low-permeability clays derived from Lake Bonneville
sediments (Appendix C) that appear to be acting as an aquitard and impeding the
downward migration of dissolved-phase contamination.
5.2.4 Vapor-Phase Contaminants of Concern and Spatial Distribution
Soil gas sampling has been conducted at twenty-eight on-site locations and three off-site
locations (Exhibit 3). Soil gas sampling data indicate the following regarding the distribution
of vapor-phase chlorinated solvent impacts:
Maximum vapor-phase PCE impacts are present on the northern and southwestern
portions of the site (Exhibit 9), while maximum vapor-phase TCE impacts are
present on the eastern portion of the site (Exhibit 10).
The lateral extents of PCE impacts appear to be defined to the west and partially
defined to the north, south, and east.
The lateral extents of TCE impacts appear to be defined to the north and west and
partially defined to the south and east.
On-site and off-site soil gas is not impacted by VC.
Limited soil gas impacts also exist for benzene and chloroform,
bromodichloromethane, ethylbenzene, and naphthalene; however, relative to PCE
and TCE, these impacts have limited distribution and low concentrations.
5.2.5 DNAPL Spatial Distribution
DNAPL has not been identified during assessment activities to date. It is considered unlikely
that additional characterization would identify a DNAPL source in an area that has not been
previously sampled.
5.3 Environmental Concerns Verification
Chlorinated solvent-impacted groundwater and soil gas have been identified at
concentrations that are either above applicable regulatory standards or at concentrations
that require additional investigation or action. This section of the updated CSM will describe
Phase 2 Site Characterization Report
SLC Station Center | Salt Lake City, Utah
October 3, 2023 | Terracon Project No. 61217142
Facilities |Environmental | Geotechnical | Materials 29
the location where the concerns exist, identify points of exposure (POEs), and evaluate
exposure pathways (EPs).
5.3.1 Chlorinated Solvent-Impacted Soil
Chlorinated solvent-impacted soil does not appear to be present at the site (Table C3).
5.3.2 Chlorinated Solvent-Impacted Groundwater
Groundwater sampling (Section 3.1;Exhibit 6 through Exhibit 8;Table C1) has confirmed
that chlorinated solvent impacts are present in groundwater at concentrations that exceed
EPA MCLs, EPA TGC VISLs, and UGWQS. Terracon conducted a search of UDEQ records for
public water system facilities and did not identify domestic or municipal groundwater supply
wells within one mile downgradient of the site. Additionally, Groundwater Permits or Water
Rights Points of Diversion were not identified within one-half mile downgradient of the site. The
chlorinated solvent-impacted groundwater does not appear to present a threat to
downgradient groundwater users.
The nearest surface water body is the Jordan River, located approximately one mile to the
west and downgradient of the site. Based on distance from the site, the chlorinated solvent-
impacted groundwater does not appear to present a threat to the identified surface water
bodies.
5.3.3 Chlorinated Solvent-Impacted Soil Gas
Soil gas sampling (Section 3.2;Exhibit 9 through Exhibit 10;Table C2) has confirmed that
chlorinated solvent impacts are present in soil gas at concentrations that exceed EPA
TSSNSGC VISLs. Limited soil gas impacts also exist for benzene and chloroform,
bromodichloromethane, ethylbenzene, and naphthalene; however, relative to PCE and TCE,
these impacts pose negligible risk to potential site receptors (Appendix F). Because the on-
site building is unoccupied and the site is generally surrounded by vacant land, there does
not appear to be a vapor intrusion risk to potential on-site or off-site receptors under
current conditions. There is one building present adjacent to the northern site boundary
where off-site PCE impacts appear to be present, but the building is used for commercial
purposes and PCE-impacted soil gas potentially present under this structure does not
exceed EPA Commercial TSSNSGC VISLs.
5.3.4 Remedial Goals
The University’s current remedial goal for the site is achievement of risk-based closure per
UAC R315-101-7(b)(1) under a “Corrective Action Complete with Controls” designation.
5.3.5 Informational Data Gaps
Terracon’s evaluation of the historical site data, historical remedial activities performed to
date, and site data from the current investigation has concluded that the significant data
gaps identified in the Phase 2 SCW have been sufficiently addressed for sorbed-phase and
Phase 2 Site Characterization Report

October 3, 2023 | Terracon Project No. 61217142
Facilities |Environmental | Geotechnical | Materials 30
dissolved-phase impacts. Some uncertainty remains regarding the off-site extent of vapor-
phase impacts, principally TCE in soil gas on the southeastern site boundary. The off-site
extent of vapor-phase TCE in soil gas on the southeastern site boundary represents a
significant data gap.
Additional off-site soil gas sampling to fully define these extents is recommended so that
risks to potential off-site receptors can be quantified and re-assessed following remediation
of dissolved-phase impacts. The eastern-adjoining property is owned by the Redevelopment
Agency of Salt Lake City (RDA). The University is actively working with the RDA to secure
access to the eastern-adjoining property for additional soil gas sampling on RDA-owned
property. The University will submit a separate work plan for the eastern off-site soil gas
assessment to DWMRC, pending property access approval by the RDA and DWMRC’s
approval of the remaining site characterization findings presented in this report.
6.0 Risk Evaluation
This section summarizes the results of the Risk Evaluation presented in Appendix F. The
results of the risk evaluation indicate that vapor-phase chlorinated solvent impacts in soil
gas exceed UAC R315-101 criteria for risk-based closure under a “Corrective Action
Complete with Controls” designation. For the most conservative exposure scenario
evaluated, under current site conditions the calculated total cancer risk is 4.76x10-5 and the
cumulative non-cancer Hazard Index is 14.01.
The EPA VISL Calculator was used to derive potential groundwater cleanup goals for the
site. Per the EPA VISL Calculator, the dissolved-phase cleanup goals required to achieve
“Corrective Action Complete with Controls” risk criteria for vapor-phase chlorinated solvents
in soil gas (cumulative carcinogenic risk of ≤1x10-4 but ≥1x10-6, cumulative non-
carcinogenic Hazard Index of ≤1.0) are presented in the table below.
Phase 2 Site Characterization Report
SLC Station Center | Salt Lake City, Utah
October 3, 2023 | Terracon Project No. 61217142
Facilities |Environmental | Geotechnical | Materials 31
In order to evaluate the potential feasibility of a cleanup to unrestricted use criteria, the EPA
VISL Calculator was used to derive potential groundwater cleanup goals that would achieve
“Corrective Action Complete without Controls” risk criteria for vapor-phase chlorinated
solvents in soil gas (cumulative carcinogenic risk of ≤1x10-6, non-carcinogenic Hazard
Index of ≤1.0). The potential dissolved-phase cleanup goals required to achieve
unrestricted “Corrective Action Complete without Controls” risk criteria are presented in the
table below.
Because vinyl chloride was non-detect in soil gas samples, the EPA VISL calculator could not
be used to estimate a Target Groundwater Concentration for vinyl chloride based on site-
specific soil gas data. Site-specific groundwater data were used to estimate this value,
which appears to be overly conservative for unrestricted use criteria given the lack of vinyl
chloride in on-site soil gas.

7.0 Conclusion
The nature and extent of VOC contamination in soil and groundwater at the site has been
sufficiently characterized to develop a remedial design that can achieve the University’s goal
of a “Corrective Action Complete with Controls” risk-based closure per UAC R315-101-
7(b)(1) criteria. The off-site extent of vapor-phase TCE impacts in soil gas on the
southeastern site boundary requires further delineation. The University will submit a
separate work plan for the off-site soil gas assessment, as detailed in Section 5.3.5.
Terracon recommends that a Corrective Action Plan (CAP) should be prepared to remediate
on-site groundwater to below the potential cleanup goals described in Section 6 (subject to
review and approval by DWMRC). On-site and off-site soil gas impacts should be addressed
via remediation of the on-site dissolved-phase chlorinated solvent source area. The CAP
should also include excavation and off-site disposal of on-site fill soils that are
geotechnically unsuitable for redevelopment of the site. The soil disturbance associated with
excavation of the fill soils should accelerate attenuation of vapor-phase impacts in soil gas
after remediation of dissolved-phase impacts is complete.

Qualifiers (Q):
J: The identification of the analyte is acceptable; the reported value is an estimate.J4: The associated batch QC was above the established quality control range for accuracy.
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.
mg/kg:Milligrams per kilogram.
RDL - Laboratory reported detection limit.
RPD - Relative Percent Difference was calculated when analyte concentrations are greater than or equal to five times the RDL. QA/QC RPD Goal is less than 50% for solid samples.
For analytes reported at concentrations less than five times the RDL, the QA/QC Goal is the difference between the sample and its duplicate is less than two times the RDL for solid samples.

PROJECT OVERVIEW
Project Summary
Between February 7-February 9, 2023, Eagle Synergistic worked with Terracon to complete a
HRSC investigation of an industrial property in Salt Lake City, UT. Direct Push technology
(DPT) services were provided by Eagle Synergistic. This investigation involved advancing 16
Membrane Interface Probe (MIP) borings to depths ranging from approximately 32-52 feet
below ground surface (bgs). The MIP was run in conjunction with the electrical conductivity
dipole (EC) and the Hydraulic Profiling Tool (HPT). Collectively, this probe configuration is
referred to as the MIHPT. The investigation had two objectives: The first objective was to
identify a suspected DNAPL/ chlorinated solvent source area. The second objective was to
delineate the chlorinated plume vertically and horizontally.

On August 22, 2023, Eagle Synergistic returned to site to complete additional MIP borings
based on the results of the February investigation. Five MIP borings were completed to depths
ranging from 32'-38' bgs. The results of this additional investigation are included in this report.

Site Access:
For the purposes of this investigation, the site was generally accessible. The investigation area
was limited to the exterior eastern half of the property, which was an open space with gravel, dirt,
asphalt or concrete surface, depending on the location.

DETECTOR INTERPRETATION
Typical standard MIP configurations use three gas phase detectors: a photo-ionization detector
(PID), flame-ionization (FID) and a halogen specific detector (XSD). The PID responds to
compounds which have an ionization potential of 10.6eV or less. These compounds include
both chlorinated and non-chlorinated hydrocarbons. The FID will respond when organic
compounds are present in the carrier gas stream at high enough concentration to combust in
the flame, which increases the flames ionization voltage. The XSD responds only to
halogenated compounds which are made up of chlorinated (most common halogenated
environmental contaminant), brominated and fluorinated compounds. Based upon which
detector or detector series a contaminant responds, we can determine if the contaminants are
halogenated, or petroleum based.
Chlorinated compounds such as trichloroethylene and perchloroethylene are detected by the
XSD and PID and respond in a similar profile. This is typical of common double bonded
chlorinated compounds which have an ionization potential below 10.6 eV. Single-bonded
chlorinated compounds such as chloroform, methylene chloride and 1,1,1,-trichloroethane have
an ionization potential above 10.6 eV, which results in a higher response on the XSD but will not
be detected by the PID.
Standard MIP systems can identify compound families and determine general compound
classes. The only sure way of determining contaminant concentration from MIP responses is to
take confirmation soil and/or groundwater samples for laboratory analysis. After obtaining the
results, the actual concentrations can be compared to the MIP detector responses and
concentrations may be estimated across the site.
In general, higher HPT pressure values indicate more compact soil. Likewise, higher EC values
indicate smaller grain size, increased pore-fluid conductivity, or higher compaction. HPT is
simply measuring the pressure required to maintain a set flow of water injected into the side-wall
soil. The EC is measuring how readily an electrical current can pass through the soil. A tighter,
more compact soil will display higher values than a looser, less compact soil.
Generally, EC values and HPT pressure should trend together. When the EC reads a lower
value (coarser-grained material (e.g., sand or gravel) the HPT pressure tends to generally read
lower in that interval as the sand/gravel will accept the injected water with ease. When the EC
reads a higher value (finer-grained material, (e.g., silts and clays) HPT pressure tends to read
higher. In tight, impermeable clays, HPT pressure can often reach 110 pounds per square inch
(PSI), the system maximum pressure, while EC values may range from 10-400 milli Siemens
per meter (mS/m).
This report, and the information contained herein, consists solely of qualitative information
provided to the recipient for its own independent use. Eagle Synergistic will not provide to the
recipient or owner(s) of the subject property any recommendations related to this report or any
information contained herein, and Eagle Synergistic hereby disclaims all responsibility related to
the same.

UNDERSTANDING EC AND HPT DATA
EC (Electrical Conductivity):
• Soil conductivity, in general, varies with grain size.
• Fine-grained soils, such as silts or clays, tend to produce higher EC signals than coarse-
grained sands and gravels.
• The EC can also detect salts, metals, etc.

HPT Pressure
As shown in the figure below, water from a supply tank (A) is pumped by a pump (B) housed
within the HPT controller at a set flow rate through the trunkline (D) and into the formation after
passing through the injection screen (F). HPT system injection pressure measurements are
made using a downhole pressure transducer (E). Use of a transducer in the downhole position
allows measurement of the injection pressure at the HPT screen only and excludes frictional
losses through the flow tube of the HPT trunkline. The downhole transducer position is also
necessary for making hydrostatic pressure measurements at the probe.

UNDERSTANDING MIP DETECTORS
During normal MIHPT operation, the general detection limit of most compounds is around 1ppm. For ppb
concentrations, the Low -Level MIHPT configuration is recommended. Contact Eagle Synergistic for further details.
Photo Ionization Detector (PID)
The PID uses ultraviolet radiation to ionize molecules in the effluent of the MIP carrier gas stream for
analyte detection. The PID is a non-destructive detector and can therefore be used in series with other
detector types. For a compound to be detected by a PID the chemical must have an ionization potential
below the electron voltage of the PID lamp. The most common PID lamp used with the MIP is 10.6eV.
The PID is generally used for detection of aromatic hydrocarbons such as benzene and toluene and
double bonded chlorinated compounds such as trichloroethylene and perchloroethylene.
Flame Ionization Detector (FID)
The FID uses a hydrogen/air flame to produce ions and electrons that can conduct electricity through the
flame. A potential is applied across the burner tip and the collector electrode. The resulting current is then
amplified and recorded. The FID will respond to any organic compound at a large enough concentration.
The FID has a lower sensitivity to common VOC analytes compared to the PID or XSD, and typically
serves as a confirmation detector run in tandem with the PID and XSD. It is, however, the primary
detector for mapping methane impacts since methane does not show up on the other detectors..

O: 303-305-7783 | www.EagleSynergistic.com | D: 720-475-0022
Halogen Specific Detector (XSD)
The XSD operates in an oxidative state that converts halogenated organics into free halogen atoms.
These halogen (X) atoms are adsorbed onto the activated platinum surface of the detector probe
assembly resulting in an increased thermionic emission. This emission current comprised of free
electrons, negative and positive ions which provides a corresponding voltage that is measured via an
electrometer circuit in the detector controller. The XSD is a destructive detector used for the detection of
total halogenated VOCs in the MIP system.

HRSC DATA OVERVIEW

Lithology:
From surface to ~10’ bgs, many borings displayed variable EC/HPT responses. Some locations,
e.g., MIP-02 and MIP-07, displayed anomalous EC values beyond those seen at other locations;
this is likely due to the presence of metallic debris in the shallow fill at these locations. Below
approximately 10’ bgs, most borings displayed a similar EC/HPT profile: Generally, an area of
lower permeability is seen from 10-15’bgs. This clayey interval is often punctuated by several
more-permeable intervals of lower HPT pressure. HPT/EC values below are consistent with
generally interbedded clays and silts. HPT data was not collected on MIP-18, 19, 20, or 21.
Interpretation
Lower magnitude, but significant, PID/XSD responses were observed across much of the
southern investigation area. Many of these impacts were observed between 15 and 25’ bgs.
Moving north, beyond the historic remedial injection area, higher magnitude PID/XSD responses
were observed at increasingly shallow depths. MIP-12 and MIP-13 displayed the highest
magnitude XSD responses across the greatest vertical extent. MIP-15 and MIP-21 also displayed
significant XSD response and was notably the highest magnitude response observed above the
known groundwater table. Many of these elevated XSD responses coincided with areas of
increased EC and/or HPT pressure, indicating a potential relationship between lithology and
presence of chlorinated compounds.
It is also worth noting that significant FID responses were observed in every boring below
approximately 20’ bgs. These FID responses were generally not accompanied by PID responses,
potentially indicating the presence of methane. Per discussion with D. Dean, this is not uncommon
for the area.

O: 303-305-7783 | www.EagleSynergistic.com | D: 720-475-0022
QUALITY ASSURANCE
All probes contain an electrical conductivity dipole, which is tested for performance prior to the
tooling being advanced. The dipole is tested using a low-value resistor and a high-value
resistor, and the results for this test are presented with each boring log. 
HPT ports and transducers are tested for performance prior to advancement using a reference
tube, which allows the static pressure of a 6-in water column to be measured. We ensure that
the transducer reads this value within a reasonable margin of error. This test is performed at the
beginning and end of each boring, and the results are included.
Membrane Interface Probes and the necessary gas chromatograph detectors are tested
simultaneously using site-specific chemical standards of known concentrations. These
standards are determined and mixed before work begins. Testing involves heating the MIP
probe while it is at the surface and placing the standard directly onto the membrane.
The contaminant then passes through the membrane and is carried into the chromatograph,
where it is picked up by the various detectors, (PID, FID, XSD). For this site, Eagle Synergistic’s
field specialists used standards of 1, 10, and 100 ppm of TCE. The response from each detector
is recorded to ensure they are within the operating range. Additionally, the “trip time” (the time it
takes for the contaminant to travel from the membrane to the gas chromatograph) is also
recorded. 
These QA/response tests are completed before and after each individual boring to ensure that
the system is functioning correctly and responding well to the site-specific contaminant of
concern. All QA/response logs are automatically compiled by the software and are available at
the client’s request.

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

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

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

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
(dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry)Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry)Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J2 Surrogate recovery limits have been exceeded; values are outside lower control limits.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.

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

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.
(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.
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
E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial
calibration (ICAL).
J The identification of the analyte is acceptable; the reported value is an estimate.
J1 Surrogate recovery limits have been exceeded; values are outside upper control limits.

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

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

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

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

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

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

Exhibit 1 (Appendix A) presents the site location on a portion of the United States Geologic
Survey (USGS) topographic map.
1.2 Background Information
The site has a long history of industrial uses including automobile and heavy equipment
repair, heating plants, a paint shop, a landscaping and erosion control contractor, and other
miscellaneous industrial-type clients from the early 1900s through 2022. The site was most
recently occupied by WRR Industries, Inc., a landscaping and erosion control contractor.
The buildings on the property were used for office space and dry storage of miscellaneous

new and old stock materials such as auto parts, landscaping equipment, vehicle storage,
and diesel truck repair bays.
Terracon completed Phase I Environmental Site Assessments (ESA) at the site in 2018 and
2021 (Terracon 2018; Terracon 2021). The Phase I ESAs identified multiple Recognized
Environmental Conditions (RECs) including a long history of industrial use and the presence
of sumps, staining, oil-water separators, leaking drums, and adjacent sites with known
contamination (Quality Plating).
To evaluate conditions associated with the identified RECs, Terracon performed a Limited
Site Investigation in 2017 (LSI; Terracon 2017). The 2017 LSI involved advancement of
eight boreholes (B-1 through B-8 on Exhibit 2) to 15 feet below ground surface (bgs) to
evaluate on-site soil and groundwater impacts from the historical industrial uses of the site
and adjacent properties.
The LSI results indicated that a portion of on-site groundwater was impacted by the
presence of several dissolved-phase chlorinated volatile organic compounds (VOCs)
including tetrachloroethene (PCE), trichloroethene (TCE), cis-1,2-dichloroethene (DCE),
trans-1,2-dichloroethene (trans-1, 2 DCE), and vinyl chloride (VC). The highest
concentration of PCE was present at boring B-3 at a concentration of 34.1 mg/L which
indicated the potential presence of dense non-aqueous phase liquid (DNAPL). The source of
the contaminants was not identified, but the highest concentrations of PCE at boring B-3
were located near an oil-water separator in the northeastern portion of the site. The LSI did
not identify VOC impacts in site soils. The LSI identified nominal petroleum impacts in site
soils and groundwater and did not identify metals impacts in site soils and groundwater
(Terracon 2017).
Additional site investigation was subsequently performed by Environmental Contractors
Incorporated (ECI) during 2018. ECI advanced seven additional soil borings in March 2018
and August 2018 (B-9 through B-15 on Exhibit 2) to further define the horizontal extent of
groundwater VOC contamination (ECI 2018). Five monitoring wells (MW-1 through MW-5 on
Exhibit 2) were subsequently installed by ECI (ECI 2020).
ECI engaged the Utah Department of Environmental Quality, Division of Waste Management
and Radiation Control (DWMRC) to provide remediation oversight in September 2018.
Multiple remedial Work Plans and Corrective Action Plans (CAP) were prepared by ECI and
submitted to DWMRC. The following structural demolition, soil removal, and groundwater
remediation was subsequently conducted by ECI at the site from 2018 to 2021 per the
DWMRC-approved plans.
The lean-to structure located south of the former boiler room was demolished
(ECI 2020).
The concrete floor of the former boiler room, the oil/water separator, and
associated soil to a depth of approximately 12 feet bgs were removed (ECI
2020).

A groundwater extraction trench and stacked-tray air stripper were operated in
the northeast area of the site from April 2019 through November 2019 (ECI
2020).
From March 2020 to July 2020, approximately 8,066 pounds of 97%
remediation-grade crystalline potassium permanganate (KMnO4) ~4% solution
was added to extracted groundwater and re-injected via trenches and eight soil
borings (ECI 2020).
From June 2021 to October 2021 approximately 4,630 pounds of ~4% KMnO4
solution was added to extracted groundwater and re-injected via 14 soil borings
(ECI 2022).
Structural demolition and associated soil removal conducted by ECI was conducted for
assessment purposes and not to address a specific known source area. PCE, TCE, and VC
were reported above United States Environmental Protection Agency (EPA) Maximum
Contaminant Levels (MCLs) in site groundwater during ECI’s final sampling event conducted
in September 2021 (ECI 2022) as summarized below:
PCE was reported at concentrations of 0.01 mg/L and 11.1 mg/L at MW-2 and
MW-3, respectively, which exceeded the MCL of 0.005 mg/L.
TCE was reported at a concentration of 0.0466 mg/L at MW-2, which exceeded
the MCL of 0.005 mg/L.
VC was reported at concentrations of 0.055 mg/L, 0.0162 mg/L and 0.0079
mg/L at MW-2, MW-3, and MW-4, respectively, which exceeded the MCL of
0.002 mg/L.
ECI’s September 2021 groundwater sampling results indicated that PCE concentration
rebound occurred at MW-3, suggesting incomplete remediation of the VOC plume. PCE
concentrations at MW-3 were reported at <0.001 mg/L in July 2021, increased to 18.4 mg/L
in August 2021, then declined to 11.1 mg/L in September 2021. TCE at MW-3 experienced
concentration rebound from July 2021 to August 2021, rising from <0.001 mg/L to 5.75
mg/L, and then declining to <0.001 mg/L in September 2021. VC concentrations rebounded
at MW-2, MW-3, and MW-4 in August 2021 and/or September 2021. Detectable
concentrations of additional VOC compounds were reported in MW-1, MW-2, MW-3, MW-4,
and MW-5 in September 2021 (ECI 2022). However, the VOC concentrations were below
MCLs.
Because ECI’s September 2021 groundwater sampling results exceeded DWMRC’s risk-
based closure criteria, Terracon subsequently conducted groundwater sampling, soil gas
sampling, and a high-resolution site characterization survey (HRSC survey) in January and
February 2023. Terracon’s January–February 2023 investigation documented ongoing VOC
impacts in groundwater in the existing monitoring wells, VOC impacts in soil gas, and a
potential extension of the chlorinated solvent plume in groundwater on the northern portion
of the site. The January–February 2023 investigation is fully detailed in the Site
Characterization Report (SCR) (Terracon 2023a).

Terracon’s January–February 2023 investigation concluded that the nature and extent of
VOC contamination in soil, groundwater, and soil gas at the site had not been fully
characterized and that the chlorinated solvent occurrences exceeded UAC R315-101 criteria
for risk-based closure.
Additional sampling of soil, groundwater, and soil gas was conducted in August 2023 to
attempt to fully characterize the nature and extent of chlorinated solvent impacts at the
site. Based on the results from the August 2023 sampling, Terracon determined that the
nature and extent of VOC contamination in soil, groundwater, and soil gas at the site has
been sufficiently characterized to develop a remedial design (Terracon 2023b).

2.0 Conceptual Site Model
Terracon prepared this Risk Evaluation using the EPA’s online Regional Screening Level
(RSL) Calculator and (https://epa-prgs.ornl.gov/cgi-bin/chemicals/csl_search) and Vapor
Intrusion Screening Level (VISL) Calculator (https://epa-visl.ornl.gov/cgi-bin/visl_search) to
evaluate the cumulative risk posed by VOCs present at the site in soil, groundwater, and soil
gas. The first step was to develop a Conceptual Site Model (CSM), which is used to
document the potential for exposure to chemicals at the site based on the source(s) of
contamination, the release mechanism(s), potential routes of exposure (ROE),
representative concentrations of contaminants of interest (COI), and receptors (i.e.,
property occupants) in order to evaluate site-specific risks associated with the COIs
remaining. Soil and groundwater sampling locations are presented in Exhibit 2 and soil gas
sampling locations are presented in Exhibit 3 (Appendix A). A graphical representation of
the CSM is presented as Exhibit 4 (Appendix A).
The objective of the Risk Evaluation was to evaluate whether impacted soil, groundwater,
and soil gas is contaminated to the extent it poses a human health risk at levels above
target maximum risk levels and hazard indices. COI concentrations in soil were compared to
EPA’s RSLs. COI concentrations in groundwater and soil gas were compared to EPA’s Target
Groundwater Concentration (TGC) and Target Sub-Slab and Near-source Soil Gas
Concentration (TSSNSGC) VISLs. Concentrations of some individual COIs in groundwater
and soil gas exceed these screening levels specific to those individual COIs.
In addition, the potential exists that the cumulative effect of all the remaining COIs would
present a risk that exceeded the acceptable target excess carcinogenic and non-
carcinogenic risk. To evaluate the cumulative risk, Terracon utilized EPA’s RSL Calculator
and VISL Calculator to evaluate either the 95% Upper Confidence Limit (UCL95) or the
maximum detected concentration1 for all analytes that were detected above laboratory
method detection limits. The following subsections describe the key elements and aspects of
the Risk Evaluation.

2.1 Sources, Release Mechanisms, and Affected Media
The site has a long history of industrial uses including automobile and heavy equipment
repair, heating plants, a paint shop, a landscaping and erosion control contractor, and other
miscellaneous industrial-type clients from the early 1900s through 2022. The site was most
recently occupied by WRR Industries, Inc., a landscaping and erosion control contractor.
The buildings on the property were used for office space and dry storage of miscellaneous
new and old stock materials such as auto parts, landscaping equipment, vehicle storage,
and diesel truck repair bays. Sumps, staining, oil-water separators, leaking drums, and
adjacent sites with known contamination (Quality Plating) were found to be present at the
site, and visual evidence of a parts cleaning station that utilized chlorinated solvents is
present at the site.
Investigations conducted at the site have identified chlorinated solvent-impacted
groundwater and soil gas. COIs and Exposure Point Concentrations (EPCs) used for risk
calculations are listed in Table 1 through Table 3 (Appendix B).
2.2 Receptors and Routes of Exposure
The current and anticipated future use of the site is commercial. The current on-site
buildings are expected to be demolished in the near future and the site redeveloped. The
following routes of exposure were evaluated in this Risk Evaluation. Risks were evaluated
for commercial employee receptors and construction worker receptors.
Soil Routes of Exposure: Ingestion of soil, inhalation of vapor emissions and particulates,
and dermal contact with soil are the routes of exposure considered for soils in the Risk
Evaluation. These exposure routes are likely to be incomplete pathways for some receptors
as shown on Exhibit 4.
Groundwater Routes of Exposure: Ingestion, inhalation of vapor emissions, and dermal
contact are the routes of exposure considered for groundwater in the Risk Evaluation. These
exposure routes are likely to be incomplete pathways for some receptors as shown on
Exhibit 3.
Soil Gas Routes of Exposure: Inhalation of vapor emissions is the source of exposure
considered for soil gas in the Risk Evaluation.
2.3 Chemicals of Interest
COIs were identified as those compounds detected above laboratory detection limits. EPCs
are either the UCL95 or the maximum detected concentration where insufficient detections
were available to calculate UCL95s. EPA’s ProUCL software was used to calculate UCL95s.

3.3 Results of the Onsite Risk Evaluation
The following table summarizes the cumulative carcinogenic risk and non-cancer Hazard
Index results for the Commercial (indoor worker) scenario. Because site-specific soil gas
data is available, groundwater data was not used to calculate vapor intrusion risks for the
Commercial (indoor worker) scenario.
Carcinogenic Risk Non-Carcinogenic Hazard Index
Soil=1.36 x 10-7 Soil=0.00908
Soil Gas=4.75 x 10-5 Soil Gas=14.0
Sum of Soil, Soil Gas=4.76 x 10-5 Sum of Soil, Soil Gas=14.01
The following table summarizes the cumulative carcinogenic risk and non-cancer Hazard
Index for the Construction Worker scenario. Risks for the Construction Worker scenario
combine groundwater and soil vapor risks since each can independently influence
accumulation of VOCs within a trench (i.e., volatilization of vapors from contaminated
groundwater into the air and diffusion of vapors directly through the trench walls,
respectively).

Carcinogenic Risk Non-Carcinogenic Hazard Index
Soil=3.02 x 10-8 Soil (Adult)=0.03

Sum of Soil, Groundwater, Soil Gas
=3.86 x 10-7
Sum of Soil, Groundwater, Soil Gas=2.65
Appendix C contains the input and output information from the EPA and VURAM software.
A target organ analysis was not conducted for exposure scenarios where the cumulative
non-carcinogenic Hazard Index exceeded 1. In all exposure scenarios where the cumulative
non-carcinogenic Hazard Index exceeded 1 a single COI had a Hazard Index >1
(trichloroethene). Thus, a target organ analysis would not reduce the organ-specific Hazard
Index to ≤1.
The scenarios listed above are for comparison and worst-case scenario purposes assuming
no controls are in place (i.e., complete exposure pathways with no controls for exposure to
impacted soil, groundwater, and soil gas). As such, this evaluation results in highly
conservative risk estimates.
3.4 Potential Cleanup Criteria
Per the EPA VISL Calculator, the dissolved-phase cleanup goals required to achieve
“Corrective Action Complete with Controls” risk criteria for vapor-phase chlorinated solvents
in soil gas (cumulative carcinogenic risk of ≤1x10-4 but ≥1x10-6, non-carcinogenic Hazard
Index of ≤1.0) are presented in the table below.

SLC Station Center | Salt Lake City, Utah
October 2, 2023 | Terracon Project No. 61217142
Facilities | Environmental | Geotechnical | Materials 11
Trichloroethene 0.0218 mg/L
Vinyl Chloride 0.275 mg/L
Per the EPA VISL Calculator, the dissolved-phase cleanup goals required to achieve
unrestricted “Corrective Action Complete without Controls” risk criteria for vapor-phase
chlorinated solvents in soil gas (cumulative carcinogenic risk of ≤1x10-6, non-carcinogenic
Hazard Index of ≤1.0) are presented in the table below.
Because vinyl chloride was non-detect in all soil gas samples collected from the site, the EPA
VISL calculator could not be used to estimate a Target Groundwater Concentration for vinyl
chloride based on site-specific soil gas data. Site-specific groundwater data were used to
estimate this value, which appears to be overly conservative for unrestricted use criteria
given the lack of vinyl chloride in on-site soil gas.
4.0 Ecological Risk Assessment
The site was fully developed with commercial and residential buildings since the early
1900s. The site is in a developed commercial area. No surface water bodies are located on
the site or adjoining properties. The current and future use of the site is commercial. As
such, the site is not a viable habitat and cannot be used by potential ecological receptors as
a habitat. Per Utah Administrative Code R315-101-5(j)(3), an Application for a Waiver of an
Ecological Risk Assessment has been prepared and is included as Appendix D.
COI VISL Target Groundwater Concentration
Cis-1,2-Dichloroethene 1.05 mg/L
Tetrachloroethene 0.0652 mg/L
Trichloroethene 0.00743 mg/L
Vinyl Chloride 0.00275 mg/L

5.0 Conclusion
The current remedial goal for the site is a risk-based “Corrective Action Complete with
Controls” closure per Utah Administrative Code R315-101-7(b)(1). Calculated site risks
currently exceed UAC R315-101-7(b)(1) criteria for closure under a “Corrective Action
Complete with Controls” designation. Terracon recommends that a CAP should be prepared
to remediate on-site groundwater to below the cleanup goals described in Section 3.4. On-
site and off-site soil gas impacts should be addressed via remediation of on-site dissolved-
phase chlorinated solvent sources.

Note: Sample size is small (e.g., <10), if data are collected using ISM approach, you should use
guidance provided in ITRC Tech Reg Guide on ISM (ITRC, 2012) to compute statistics of interest.
For example, you may want to use Chebyshev UCL to estimate EPC (ITRC, 2012).

Note: Suggestions regarding the selection of a 95% UCL are provided to help the user to select the most appropriate 95% UCL.
Recommendations are based upon data size, data distribution, and skewness.
These recommendations are based upon the results of the simulation studies summarized in Singh, Maichle, and Lee (2006).
However, simulations results will not cover all Real World data sets; for additional insight the user may want to consult a statistician.
Recommended UCL exceeds the maximum observation
In Case Bootstrap t and/or Hall's Bootstrap yields an unreasonably large UCL value, use 97.5% or 99% Chebyshev (Mean, Sd) UCL

General Statistics
ProUCL computes and outputs H-statistic based UCLs for historical reasons only.
H-statistic often results in unstable (both high and low) values of UCL95 as shown in examples in the Technical Guide.
It is therefore recommended to avoid the use of H-statistic based 95% UCLs.
Use of nonparametric methods are preferred to compute UCL95 for skewed data sets which do not follow a gamma distribution.
Note: Suggestions regarding the selection of a 95% UCL are provided to help the user to select the most appropriate 95% UCL.
Recommendations are based upon data size, data distribution, and skewness.
These recommendations are based upon the results of the simulation studies summarized in Singh, Maichle, and Lee (2006).
However, simulations results will not cover all Real World data sets; for additional insight the user may want to consult a statistician.

General Statistics
ProUCL computes and outputs H-statistic based UCLs for historical reasons only.
H-statistic often results in unstable (both high and low) values of UCL95 as shown in examples in the Technical Guide.
It is therefore recommended to avoid the use of H-statistic based 95% UCLs.
Use of nonparametric methods are preferred to compute UCL95 for skewed data sets which do not follow a gamma distribution.
Note: Suggestions regarding the selection of a 95% UCL are provided to help the user to select the most appropriate 95% UCL.
Recommendations are based upon data size, data distribution, and skewness.
These recommendations are based upon the results of the simulation studies summarized in Singh, Maichle, and Lee (2006).
However, simulations results will not cover all Real World data sets; for additional insight the user may want to consult a statistician.

ProUCL computes and outputs H-statistic based UCLs for historical reasons only.
H-statistic often results in unstable (both high and low) values of UCL95 as shown in examples in the Technical Guide.
It is therefore recommended to avoid the use of H-statistic based 95% UCLs.
Use of nonparametric methods are preferred to compute UCL95 for skewed data sets which do not follow a gamma distribution.
Note: Suggestions regarding the selection of a 95% UCL are provided to help the user to select the most appropriate 95% UCL.
Recommendations are based upon data size, data distribution, and skewness.
These recommendations are based upon the results of the simulation studies summarized in Singh, Maichle, and Lee (2006).
However, simulations results will not cover all Real World data sets; for additional insight the user may want to consult a statistician.

However, simulations results will not cover all Real World data sets; for additional insight the user may want to consult a statistician.
When a data set follows an approximate (e.g., normal) distribution passing one of the GOF test
When applicable, it is suggested to use a UCL based upon a distribution (e.g., gamma) passing both GOF tests in ProUCL

General Statistics
ProUCL computes and outputs H-statistic based UCLs for historical reasons only.
H-statistic often results in unstable (both high and low) values of UCL95 as shown in examples in the Technical Guide.
It is therefore recommended to avoid the use of H-statistic based 95% UCLs.
Use of nonparametric methods are preferred to compute UCL95 for skewed data sets which do not follow a gamma distribution.
Note: Suggestions regarding the selection of a 95% UCL are provided to help the user to select the most appropriate 95% UCL.
Recommendations are based upon data size, data distribution, and skewness.
These recommendations are based upon the results of the simulation studies summarized in Singh, Maichle, and Lee (2006).

Appendix D Application For A Waiver Of An Ecological
Risk Assessment
Application for a Waiver of an Ecological Risk Assessment
SLC Station Center Site, 550 and 570 West 400 South
Salt Lake City, Salt Lake County, Utah
This application is being submitted to request a waiver for performing an ecological risk
assessment at the SLC Station Center Site, 550 and 570 West 400 South, Salt Lake City,
Utah.
In accordance with the Utah Administrative Code (UAC) R315-101, site investigations must
include an evaluation of human health and ecological risk to support risk-based closure. An
ecological risk assessment is warranted when it has been determined that exposure
pathways are potentially complete for ecological receptors. A complete pathway consists of:
1) a source, 2) a mechanism of contaminant release, 3) a receiving or contact medium, 4) a
potential receptor population, and 5) exposure route. Of these five criteria, the most
fundamental is the fourth criterion. In order for a potential receptor population to exist, a
site must contain open areas that would allow plant growth and suitable habitat for wildlife.
Pathways are incomplete for ecological receptors at sites that are completely filled-in with
buildings, concrete, or pavement. For these areas, an ecological risk assessment cannot be
completed.
The SLC Station Center property is nearly completely paved and/or covered in structures.
No significant areas of natural vegetation are present, and the site is devoid of suitable
habitat for wildlife. Additionally, the immediate vicinity of the site is industrial/commercial,
consisting of paved/concrete lots and industrial-use buildings. The surrounding area does
contain limited trees and grass (mostly in parking strips/sidewalk areas). However, no
wildlife has been observed using the property for permanent habitat or food. Although it is
possible that some species could casually be present (such as birds resting in nearby trees
or crossing the property), it is not plausible that any receptor would forage, nest, or den on
the SLC Station Center Site property itself due to a lack of vegetation.
As any potentially contaminated soil is located beneath concrete, structures, pavement, or
transported fill material, all potential areas of habitat are unavailable to ecological
receptors. Since there is no complete exposure pathway, an ecological risk assessment is
not deemed required at this facility and a waiver for conducting a quantitative ecological risk
assessment per R315-101-5(j)(3) is requested.
