1.0 INTRODUCTION

Underwood Environmental Consulting, Inc. (UEC) conducted a groundwater monitoring event
for Jacksons Companies at the Express Food and Fuel (formerly Fast Stop #1121) service station
in Vernal, Utah. The project site, located at 850 West Highway 40 (821 W. Main St. in DERR
correspondence), includes a convenience store, retail fueling facilities, and car wash (Figure 1).
Quarterly groundwater monitoring has been conducted following a reported release of unleaded
gasoline in May 2021 and a subsequent subsurface investigation in October 2021. The site is
eligible for Petroleum Storage Tank (PST) Fund reimbursement. The Utah Division of
Environmental Response and Remediation (DERR) identifies the project site as Facility ID
#9000165, Release Site OAQ.

2.0 BACKGROUND

The site has one previous release designation (JMP) related to underground storage tank (UST)
system removal in April 1996. One closure soil sample slightly exceeded the recommended
cleanup level (RCL) established at the time. A “no further action” (NFA) letter for Release JMP
was issued in May 1996 (DERR, 1996).

Release OAQ was opened based upon a release of unleaded gasoline reported in May 2021. The
release was reported based on observation of a leaking pipe gasket within the sump under a
dispenser (dispenser 5-6). The applicable UST was immediately taken out of service as a
precaution. Under dispenser repairs were promptly completed and the system was put back into
operation.

UEC performed a subsurface investigation at the site in October 2021. At that time, four
locations were drilled and sampled east of dispenser 5-6 and one location was drilled and
sampled west of the UST basin (Figure 1). No free product was observed during the subsurface
investigation. Hydrocarbons were detected, however, in soil and groundwater samples collected
east of the dispensers (UEC, 2021).

3.0 METHODOLOGY

3.1 Groundwater Monitoring

On May 8, 2025, water levels were measured in four monitoring wells using an electronic water
level indicator. The monitor wells were subsequently purged of three casing volumes of water
prior to sampling. A separate disposable bailer was utilized for each well. The groundwater
samples were labeled appropriately, placed on ice, and submitted to the laboratory under chain-
of-custody. The groundwater samples were analyzed for methyl tertiary butyl ether (MTBE),
benzene, toluene, ethylbenzene, total xylenes, naphthalene (BTEXN), total petroleum

hydrocarbons – gasoline range organics (TPH GRO), and TPH – diesel range organics (TPH
DRO) using EPA methods 8260B/C/D, and 8015C.

4.0 RESULTS

4.1 Depth to Water and Flow Direction

On May 8, 2025, the depth to groundwater ranged from 7.60 to 8.42 feet below top-of-casing
(TOC) (Table 1). Figure 1 depicts a groundwater contour map for the project site on the same
date. Based on the measured groundwater elevations, the groundwater flow direction continues
to be east-southeast.

4.2 Groundwater Analytical Results

Four monitoring wells were purged and sampled on May 8, 2025. The groundwater analytical
results presented on Table 1 are compared with Initial Screening Levels (ISLs) and Tier 1 Levels
(DERR, 2005).

Three of the four monitoring wells sampled exceeded the ISL for benzene. The highest benzene
concentration detected in groundwater was 0.645 milligrams-per-liter (mg/L) at MW-1. Two of
the four monitoring wells sampled exceeded the ISL for TPH GRO and TPH-DRO. The highest
TPH concentration detected in groundwater was 4.4 mg/L TPH-DRO at MW-1. No petroleum
hydrocarbons were detected in the groundwater sample collected from MW-4 (Table 1; Figure
1).

The laboratory analytical reports for the May 2025 groundwater monitoring event are provided
as an attachment.

5.0 CONCLUSIONS

Based on field observations and the May 2025 groundwater analytical results, the following
conclusions are presented:

• Depth to groundwater ranged from approximately 7.6 to 8.4 feet below top of well
casing.

• The groundwater flow direction continues to be east-southeast.

• The ISL for benzene was exceeded at three well locations. The highest benzene
concentration detected in groundwater was 0.645 mg/L at MW-1.

• The ISL for TPH-GRO and TPH-DRO was exceeded at two well locations. The highest
TPH concentration detected in groundwater was 4.4 mg/L TPH-DRO at MW-1.

• No petroleum hydrocarbons were detected in groundwater at MW-4.

The next groundwater monitoring event approved under Work Plan OAQ-04 is tentatively
scheduled for August 2025.

6.0 LIMITATIONS

Our services consist of professional opinions from a state-certified consultant, made in general
accordance with locally accepted environmental practices at the time of execution.
Environmental samples are obtained from specific locations, utilizing methodologies consistent
with Utah Department of Environmental Quality regulations. UEC makes no guarantee, either
expressed or implied, that the analytical results accurately represent subsurface conditions
throughout the entire project site.

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.
