Dear Mr. Goble:

Rockwell Solutions, Inc. has completed additional subsurface investigation activities at the above-
referenced facility in accordance with State of Utah Division of Environmental Response and
Remediation (DERR) guidelines.

INTRODUCTION

The site is a former gas station and auto shop at 45 North Main Street. The underground storage
tanks (USTs) were removed in April 2023. During UST closure activities hydrocarbon
concentrations exceeded Initial Screening Levels (ISLs) in a soil sample from the tank basin and
exceeded Tier 1 levels in soil samples from three dispensers. The two groundwater samples
collected in the tank basin exceeded Tier 1 levels.

A subsurface investigation was completed in September 2023 which defined the extent of soil
contamination. The extent of groundwater contamination was defined to Tier 1 levels, but not
Initial Screening Levels (ISLs). It was determined that monitoring wells should be installed to
define the extent of groundwater contamination to ISLs.

METHODOLOGY

Six monitoring wells were installed on March 27, 2024. Monitoring wells MW-4, MW-5, and MW-
9 were installed in the expected downgradient direction of known areas of contamination. MW-8
was installed in the former tank basin, and MW-6 and MW-7 were installed as cross gradient and
upgradient wells, respectively, to define the extent of contamination. Well locations are shown on
Figure 1. Direct Push Services was employed as the drilling contractor under the supervision of a
Rockwell Solutions representative.

Five-foot soil core samples were collected continuously from the direct push borings. A portion of
the soil core was put in a zip-lock baggie to allow hydrocarbons to volatilize. The air in the zip lock
baggie was then screened with a photoionization detector (PID). Laboratory samples were collected
from intervals with the highest PID readings or, if no PID readings were detected, from the soil
interval above the apparent groundwater table. Laboratory samples were analyzed for MTBE,
benzene, toluene, ethylbenzene, xylenes, naphthalene (MBTEXN) total petroleum hydrocarbons-
gasoline range organics (TPH-GRO) using EPA Method 8260 and TPH-diesel range organics
(TPH-DRO) using EPA Method 8015.

Monitoring wells were installed in each boring to a depth of eighteen to twenty feet with ten or
fifteen feet of 0.010-inch screen. The wells contain a silica sand filter around the screen and a
bentonite seal above the screen. A flush grade well protector was installed at the surface. The top-
of-casing elevation at each well was measured to the nearest 0.01 foot using a transit level.

The monitoring wells were developed and a groundwater sample was collected with a disposable
bailer. The samples were submitted for laboratory analysis of MBTEXN and TPH-GRO using EPA
Method 8260, and TPH-DRO using EPA Method 8015.

RESULTS

Soil Type
Soil type was evaluated during the subsurface investigation by field analysis of soil samples. The
native soil at the site consists of silt to a depth of approximately five to seven feet below grade
which is underlain by a well-sorted sand layer to a depth of approximately fourteen to sixteen feet
below grade. A silty clay layer is below the sand layer to at least twenty feet below grade. Boring
logs are attached.

Soil Analytical Results
Table 1 lists the analytical results of the soil samples collected during both investigations and the
tank removal. No hydrocarbon concentrations exceeding ISLs were detected in samples collected
during the subsurface investigations. The laboratory analytical reports and chain-of-custody records
for soil samples collected during the additional subsurface investigation are attached. PID readings
are shown on the boring logs.

Free Product
Approximately six inches of free product were found in MW-1, an existing monitoring well. A
groundwater sample was not collected from MW-1. An oil absorbent sock was placed in the
monitoring well.

Groundwater Depth and Flow
Table 2 lists the top-of-casing elevations and depths to water at the site monitoring wells.
Groundwater monitoring data indicates depth to groundwater is between ten and twelve feet below
grade. Groundwater flow on April 5, 2024, was to the southwest, as shown on Figure 2.

Groundwater Analytical Results
Table 2 lists the analytical results of the groundwater samples collected at the site. Other than the
free product in MW-1, no other groundwater monitoring wells contained hydrocarbon
concentrations exceeding Tier 1 levels. Monitoring wells MW-2, MW-4, MW-8, and MW-9
contained hydrocarbon concentrations meeting or exceeding ISLs. The laboratory analytical reports
and chain-of-custody records for samples collected during the additional subsurface investigation
are attached.

CONCLUSIONS AND RECOMMENDATIONS

The extent of soil has been defined to ISLs and groundwater contamination has been mostly defined
to ISLs at the site. The farthest downgradient well, MW-4, contains a TPH-DRO concentration
slightly exceeding the ISL of 1.0 milligrams per liter.

Free product has been found in MW-1. Rockwell Solutions recommends installing two to three
more wells around the north side of the building to define the extent of free product and to be used
as high vacuum dual phase extraction (HVDPE) wells to remove free product and impacted
groundwater.

Please feel free to contact me should you have any questions or concerns at 801-361-2930.

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

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.
