Dear Mr. Crim:

Please find attached the Groundwater Monitoring Report for the above referenced site.

INTRODUCTION

On December 19, 2024, Atlas Technical Consultants (Atlas) conducted a groundwater sampling
event at the former Circle C Store facility located at 1271 North Carbonville Road, Price, Utah
(see Figure 1). The work was performed on behalf of the Utah Department Environmental
Quality, Division of Environmental Response and Remediation (DERR) under Work Assignment
KXV-34. The field effort and laboratory procedures utilized to collect the information presented
in this report are discussed in the following sections.

FIELD PARAMETER WELL PURGING PROCEDURES AND CHEMICAL ANALYSIS

The approved work plan included collecting water levels from all of the monitoring wells, then
sampling monitoring wells MW -7, MW -12, and MW -13. Well head repair on MW -14 also took
place during the December 2024 monitoring event. The site map depicting the groundwater
monitoring well locations and surrounding area features is presented as Figure 1. Prior to well
purging, groundwater depth was measured in each well using an electronic water level/free
product interface probe. No free product was observed in any of the monitoring wells sampled.
The water level/free product interface probe was decontaminated between each well with an
Alconox detergent wash and tap water rinse. Following field parameter measurements all
monitoring wells were purged a minimum of three well volumes or until dry of water using new,
factory-sealed, disposable PVC bailers. Following the purging process, the wells were allowed
to recharge to within 95 percent of the pre-purge water level and then sampled. The samples
were transferred to appropriate containers and immediately placed on ice in an insulated cooler
and then transported under chain-of-custody documentation to a Utah-certified laboratory for
analysis.

The groundwater samples were analyzed for methyl t-butyl ether, benzene, toluene, ethyl
benzene, total xylenes, naphthalene (MBTEXN), using EPA Method 8260; and for total
petroleum hydrocarbons as gasoline (TPH-GRO) and TPH as diesel (TPH-DRO) using EPA
Method 8015.

Field Parameter and Chemical Analysis Results
Groundwater measurements and laboratory results are presented in Table 1. The December
2024 groundwater elevation data were utilized to prepare a groundwater contour map (Figure 2)
for the site. The groundwater flow direction appears to be toward the south-southeast as
measured between MW -11 and MW -7 at a gradient of 0.033 feet/foot.

Review of the December 2024 data indicate the presence of benzene above its Initial Screening
Level (ISL) of 0.005 mg/L in MW -12 (0.538 mg/L) and MW -13 (1.570 mg/L). No other MBTEXN
constituents were measured above their respective ISLs. Benzene was also detected in MW -7
(0.000927 mg/L). The Benzene Isoconcentration Map is presented as Figure 3.

The TPH-GRO Initial Screening Level of 1.0 mg/L was exceeded in MW -12 (3.950 mg/L) and
MW -13 (14.500 mg/L). TPH-GRO was not detected in MW -7. The TPH-GRO Isoconcentration
Map is presented as Figure 4. The TPH-DRO Initial Screening Level of 1.0 mg/L was also
exceeded in MW -12 (3.160 mg/L) and MW -13 (13.700 mg/L). TPH-DRO was also detected in
MW -7 (0.0749 mg/L). The laboratory data are summarized in Table 1 and a copy of the
laboratory report is included in Appendix A.

CONCLUSIONS AND RECOMMENDATIONS

The results of the December 2024 groundwater monitoring event indicate the detection of
benzene above its ISL in MW -12 and MW -13. No other MBTEXN constituents were measured
above their respective ISLs in any of the other wells sampled. The TPH-GRO and TPH-DRO
ISLs were exceeded in MW -12 and MW -13. Based upon review of the December 2024
groundwater data, and review of historical groundwater data, Atlas recommends that semi-
annual groundwater monitoring continue at the site. The December 2024 groundwater
monitoring event was the third monitoring event under work assignment KXV-34. The next
groundwater monitoring event is scheduled for June 2025.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. 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.
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.
