Re: Subsurface Investigation
New Logan Market Facility ID: 0100093
720 E 1000 North Release ID: OMC
Logan, Utah

Dear Mr. Singh:

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

INTRODUCTION

The New Logan Market is a former gas station at 720 E 1000 North in Logan. Groundwater closure
samples collected from the former tank basin in November 2024 exceeded Tier 1 levels and a
release was reported. DERR assigned the site release code OMC and requested a subsurface
investigation.

The USTs and fuel system were removed as well as the canopy in November 2024 and the site is
currently a convenience store and a restaurant.

Most utility lines for the facility run from 700 East to the onsite building. The water line to the
building runs along the east side of the property. Figure 1 shows the locations of utility lines.

METHODOLOGY

Five borings were installed in and around the former tank basin on January 17, 2025 using direct
push methodology. 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). The sample with the highest PID
reading or the soil interval above the apparent water table in each boring was submitted for

laboratory analysis of 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. No soil sample was collected
from boring B-5 which is located in the backfill of the former tank basin.

Groundwater was encountered at approximately five feet below grade (bg). Groundwater samples
were collected using a peristaltic pump from each boring. 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 generally consists of silt (ML) to at least ten feet bg. Boring logs are attached.

Soil Analytical Results
Table 1 lists the analytical results of the soil samples collected during the subsurface investigation.
All concentrations were below Initial Screening Levels (ISLs). The laboratory analytical reports
and chain-of-custody records for soil samples collected during the subsurface investigation are
attached. PID readings are shown on the boring logs.

Groundwater Analytical Results
Table 2 lists the analytical results of the groundwater samples collected during the subsurface
investigation. The sample from B-5, in the former tank basin, exceeded Tier 1 levels. The sample
from B-3 slightly exceeded the ISL for TPH-GRO. Hydrocarbons were not detected in the other
borings. Figure 2 shows the approximate extent of groundwater contamination at the site. The
laboratory analytical reports and chain-of-custody records for samples collected during the
subsurface investigation are attached.

TIER 1 CRITERIA

Land Use
The site is located in a mixed commercial and residential area. The nearest residence is
approximately 125 feet to the north.

Utilities
Locations of buried utility lines in the investigation area were discussed previously. Depth of the
water line on the east side of the site is five feet. The exact depths to the other utility lines are not
known, but are estimated to be approximately two to three feet.

Receptors
A well search of the Water Rights database indicates no water rights are located within 500 feet of
the site. See Figure 3.

CONCLUSIONS AND RECOMMENDATIONS

No soil contamination has been detected in the UST removal sampling or during the subsurface
investigation. Groundwater contamination is present onsite from the former tank basin and
extending to the approximate western property boundary. Rockwell Solutions recommends
installing monitoring wells to collect additional groundwater contamination and flow information to
determine if active remediation is necessary or if the natural attenuation of the contamination can be
monitored.

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

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.
