Re: Report
Subsurface Soil Assessment – Observations
Former Construction Power Solutions Property
805 North Redwood Road
North Salt Lake City, Utah

GSH Geotechnical, Inc. (GSH) is pleased to submit the results of the limited subsurface soil
assessment (Oil & Grease, TPH-GRO, TPH-DRO, and VOCs) for the subject property located at
805 North Redwood Road in North Salt Lake City, Utah. This report includes discussions
concerning our investigative methods, the scope of the work performed, and the analytical results
of the collected samples.

A Phase I Environmental Site Assessment 1 (ESA) was completed by Gordon Geotechnical
Engineering, Inc. for the subject property on March 29, 2023. Within the ESA, Gordon
Geotechnical Engineering identified the subject property to have historically stored and fueled
asphalt-tar sealing construction equipment as well as an open LUST case on the property. A diesel
fuel spill from a broken pipe, surficial staining of what appeared to be petroleum products, and a
partially buried, corrugated pipe storage tank was also identified within the report during the site
visit.

Due to these RECs, a Limited Phase II ESA 2 was conducted, by Gordon Geotechnical Engineering,
in order to determine whether contamination was present on the subject property. The report
identified soil and/or groundwater samples above the initial screening levels for Diesel Range
Organics (TPH-DRO), Gasoline Range Organics (TPH-GRO), Benzene, Oil and Grease (HEM),
and TPRH (SGT-HEM).

On May 12, 2023, Wasatch Environmental completed a Subsurface Investigation Report 3 to
further investigate the known petroleum impacts at the site, investigate potential releases, and to
evaluate potential surface soil impacts at the site. Seventeen (7) borings were drilled, and the

results identified soil and/or groundwater samples to be above the initial screening levels for Diesel
Range Organics (TPH-DRO), Gasoline Range Organics (TPH-GRO), Oil and Grease, and TPRH.

The following report provides further analysis of subsurface soil and groundwater at the subject
property to identify the concentrations of contamination and the relevant requirements associated
with each concentration.

The effective date of this report is April 16, 2024. We recommend that this report be read in its
entirety by all interested parties for a comprehensive understanding of the assessment.

INTRODUCTION

GSH was requested to provide a limited subsurface soil and groundwater assessment. The
following paragraphs describe procedures associated with sampling and testing.

On March 28th, 2024, GSH drilled 7 borings to 15.0 feet within the vicinity of the Former
Construction Power Solutions Property. A 2.0-inch outside diameter, 1.38-inch inside diameter
drive sampler (SPT) was utilized in the subsurface soil sampling at the subject property. The
borings were drilled using a moderate-size truck-mounted rotary drill rig, and boreholes were
advanced using hollow-stem augers.

Two (2) soil samples were extracted from each of the 7 boreholes at varying depths between
1.0 and 15.0 feet below the ground surface (bgs). The soil samples were placed into laboratory-
provided sampling jars. The sample jars were then labeled with a sample identification number to
correspond with the extraction location and the chain-of-custody.

Following drilling, 1-1/4’’ slotted Polyvinyl pipes (PVC) were installed within the borings at
depths below the groundwater elevation. The PVC pipes were subsequently accessed for
groundwater sampling.

Groundwater was extracted at a depth of approximately 5-10 feet, using a groundwater bailer
within the PVC pipes. A new uncontaminated one-quarter-inch polyethylene tube was slowly
lowered into each boring. Groundwater was transferred to 4 laboratory-provided 40-ml glass vials,
sealed with no head space and a 1-liter glass container. Each sample was properly labeled to
correspond with boring location and chain-of custody records and then placed in a cooler until
transported to Chemtech-Ford Laboratories.

Samples were transported to Chemtech-Ford Laboratories, a Utah-certified laboratory, under an
appropriately filed chain-of-custody record. These samples were tested for Diesel Range Organics
(DRO), Gasoline Range Organics (GRO), Volatile Organic Compounds (VOCs), and Oil and
Grease (TRPH). Fourteen (14) soil samples and seven (7) groundwater samples were taken from
the site and processed during the time frame of this report.

CONCLUSIONS AND OPINIONS

GSH has completed a limited subsurface assessment and has determined that concentrations of
TPH-DRO and Oil and Grease are over the Initial Screening Limits for soil samples B-2 #1, B-5
#1, and B-6 #1. TPH-GRO and VOCs are under regulatory limits for these samples. Soil samples
B-2 #2 and B-4 #1 are also over the Initial Screening Limits for TPH-DRO. TPH-GRO, Oil and
Grease, and VOCs are under regulatory limits for samples B-2 #2 and B-4 #1. The Initial Screening
Limit for TPH-DRO in soil is 500 (mg/kg) and 1000 (mg/kg) of Oil and Grease. Soil samples
listed above range from 544-5320 (mg/kg) of TPH-DRO and 8420-20800 (mg/kg) of Oil and
Grease. All other soil samples are under regulatory limits for TPH-GRO, TPH-DRO, Oil and
Grease, and VOCs.

All groundwater samples are within the Initial Screening Limits for TPH-DRO. Samples B-1,
B-2, B-3, B-4, B-6, and B-7 are over the Initial Screening Limits for TPH-GRO. Samples B-1,
B-2, and B-7 are over the Initial Screening Limits for Oil & Grease. Sample B-1 is over the Initial
Screening Limit for 1,2,4-Trimethylbenzene. All other groundwater samples are within the Initial
Screening Limits for VOCs

Testing results are included within Appendix A.

Due to limited scope, there is always a possibility that existing contaminants could escape
detection using the methods employed. The conclusions in this report are probabilities based on
industry-accepted methods and best professional judgement concerning the significance of the data
gathered.

Based on the current concentration of the encountered contaminants, GSH recommends the
following:

• A suitable vapor barrier should be installed below all future structures to reduce the
risk of vapor intrusion.

• Exterior pavement, such as asphalt or concrete, acts as a cap and is anticipated to
provide sufficient protection for human health. All landscaping should have a

Report Footnotes
Abbreviations
ND = Not detected at the corresponding Minimum Reporting Limit (MRL).
1 mg/L = one milligram per liter or 1 mg/kg = one milligram per kilogram = 1 part per million.
1 ug/L = one microgram per liter or 1 ug/kg = one microgram per kilogram = 1 part per billion.
1 ng/L = one nanogram per liter or 1 ng/kg = one nanogram per kilogram = 1 part per trillion.
On calculated parameters, there may be a slight difference between summing the rounded values shown on the report
vs the unrounded values used in the calculation.
Flag Descriptions
J = Detected but below the Reporting Limit; therefore, result is an estimated concentration (CLP J-Flag).
J-LOW-L = Estimated low due to low recovery of LCS

Report Footnotes
Abbreviations
ND = Not detected at the corresponding Minimum Reporting Limit (MRL).
1 mg/L = one milligram per liter or 1 mg/kg = one milligram per kilogram = 1 part per million.
1 ug/L = one microgram per liter or 1 ug/kg = one microgram per kilogram = 1 part per billion.
1 ng/L = one nanogram per liter or 1 ng/kg = one nanogram per kilogram = 1 part per trillion.
On calculated parameters, there may be a slight difference between summing the rounded values shown on the report
vs the unrounded values used in the calculation.
Flag Descriptions
J = Detected but below the Reporting Limit; therefore, result is an estimated concentration (CLP J-Flag).
J-LOW-C = Estimated low due to low recovery of CCV
J-LOW-L = Estimated low due to low recovery of LCS
