Dear UDEQ DERR Project Manager:
Antea®Group submits this report on behalf of Parkland Fuel Corp. (Parkland), as a summary of the high vacuum dual
phase extraction (HVDPE) event and groundwater sampling data collected from well MWH-2 at the above-referenced
facility. The scope of work was conducted according to the Work Plan submitted to the Utah Department of
Environmental Quality Division of Environmental Response and Remediation (DERR) on March 14, 2024, and approved by
the DERR on April 10, 2024.
Summary of Background Information
The Hart’s Gas and Food site is located at 335 W 7200 S, Midvale, Utah. The elevation of the site is approximately 4,383
feet above mean sea level and the topography of the area slopes to the west. The site is currently an active retail gas
station with a station building, fueling canopy, and six dispenser islands. The site is paved with asphalt and concrete. A
site map is included as Figure 1.
The site has been reported to have been occupied by a retail gasoline service station which originally utilized three steel
Underground Storage Tanks (USTs) since 1971. The steel USTs were closed and removed from the site in October 1998.
During closure activities, contaminated soil was discovered in the UST basin area. A release was reported to the DERR on
October 26, 1998 and was assigned release ID # KRP. Impacted soil was over-excavated and hauled off-site. Release KRP
was issued a No Further Action (NFA) letter in September 1999. In December 1998, four fiberglass reinforced plastic USTs
were installed within the original tank basin. No known releases have occurred from the current UST system.
In January 2000, a release was discovered at the Chevron gasoline station located to the west across Cottonwood Street.
Numerous subsurface investigations and groundwater monitoring events have occurred at the Chevron facility to define
and evaluate the magnitude and extent of the release. To help delineate the Chevron facility’s release, three sets of
nested monitoring wells (MW-14/MW-14A, MW-15/MW-15A, MW-16/MW-16A) were installed on Midvale City Right-of-
Way (sidewalk), located within close proximity to the Hart’s western property boundary. Nested monitoring wells MW-
14/MW-14A, MW-15/MW-15A, MW-16/MW-16A have historically provided intermittent groundwater for the collection
of water samples and laboratory analysis. When groundwater has been present, analytical results have indicated
contaminants of concern (CoCs) in samples collected from MW-14 exceeding DERR Initial Screening Levels (ISLs) and
water collected from MW-14A containing CoCs exceeding Tier 1 screening levels.
On October 2016, the DERR directed a State contracted consultant to perform a subsurface investigation on the Hart’s
property to evaluate on-site conditions for a potential source of the identified CoCs in MW-14 and MW-14A. The
subsurface investigation included five soil borings using direct push technology. All borings were completed with

monitoring wells (MWH-1 through MWH-5). Due to insufficient groundwater volumes in MWH-1 through MWH-4,
groundwater samples were only collected from MWH-5. While the report concluded that no specific source was
identified, on-site soil impacts were detected above Tier 1 Screening Levels in the MWH-3 boring at a depth of 22 feet.
Results from the subsurface Investigation can be found in the Subsurface Investigation Report submitted on January 20,
2017 by ATC Group Services.

On June 18, 2018, a groundwater monitoring event was performed by Underwood Environmental. The monitoring event
included gauging two wells on the adjoining Chevron site (MW-1, MW-7) one well in the 7200 South right-of-way (MW-
6), eight wells in the Cottonwood Street right-of-way (MW-8, MW-14, MW-14A, MW-15, MW-15A, MW-16, MW-16A,
MW-19) and four wells on the Harts site (MWH-1, MWH-2, MWH-3, and MWH-4). Additionally, well MWH-5 located
across 7200 South to the northwest was gauged. Of the 16 wells gauged, only wells MW-6, MW-7, MW-14, MWH-2, and
MWH-5) contained sufficient water to collect samples. Laboratory results indicated that monitoring wells MW-14 and
MWH-2 exceeded the (ISLs) for one or more hydrocarbon constituents. MW-14 detected benzene at 0.008 mg/L and
MWH-2 detected benzene at 0.018 mg/L, Total Petroleum Hydrocarbons as Gasoline (TPH-GRO) at 1.48 mg/L, and Total
Petroleum Hydrocarbons as Diesel (TPH-DRO) at 2.5 mg/L. The groundwater flow direction was determined to be
towards the south-southeast.

On October 12 and 13, 2020, Antea Group conducted an on-site soil investigation to further evaluate the extent of the
on-site impacted soil. The investigation consisted of the advancement of five soil borings using direct push technology.
Soil samples were collected continuously beginning at five feet and were screened for volatile organic compounds using
a Photoionization Detector (PID). Three soil samples were collected for laboratory analysis from each soil boring within
the zones of highest PID readings or at the bottom of the boring. Soil analytical results detected COCs above ISLs and Tier
1 Screening Criteria in soil samples collected from soil borings SB-1, SB-2, SB-3, and SB-4. Soil analytical data is included
as Table 1. Additionally, monitoring wells (MWH-1 through MWH-5) were gauged and sampled on October 14, 2020.
MWH-3 and MWH-4 were gauged as dry and were not sampled. Groundwater samples were submitted to Pace National
of Mount Juliet, Tennessee to be analyzed for Benzene, Toluene, Ethylbenzene, Xylenes, Naphthalene (BTEXN), Methyl
Tert-Butyl Ether (MTBE), TPH-GRO, and TPH-DRO using EPA Methods 8260 and 8015. Groundwater analytical results
indicated that MWH-2 exceeded Tier 1 Screening Criteria for TPH-DRO at 16.5 mg/L and exceeded ISLs for Benzene at
0.100 mg/L and TPH-GRO at 3.04 mg/L.

On June 16, 2021, groundwater monitoring of wells MWH-1 through MWH-5 gauged and sampled. Monitoring wells
MWH-3 and MWH-4 were gauged as dry and could not be sampled. Wells MWH-1, MWH-2, and MWH-5 had detectable
groundwater at depths between 30.91 in MWH-5 and 37.03 in MWH-1. The observed intermittent occurrence of
groundwater in the on-site wells indicated the saturated zones observed in MWH-1 and MWH-2 were not continuous,
and a groundwater flow direction across the well network could not be determined. In MWH-2, 0.17 feet of Light Non-
Aqueous Phase Liquid (LNAPL) was observed. Groundwater samples from MWH-1, MWH-2, and MWH-5 were submitted
to Pace National of Mount Juliet, Tennessee, and analyzed from BTEXN, MTBE, TPH GRO, and TPH DRO using EPA
Methods 8260 and 8015. In MWH-1 and MWH-5 no COCs were detected above ISLs. Benzene exceeded Tier 1 Screening
Criteria in MWH-2 at a concentration of 0.455 mg/L. TPH-GRO exceeded ISLs at MWH-2 at a concentration of 3.36 mg/L.
The groundwater sample from MWH-2 received a laboratory “J2” TPH-DRO qualifier, which indicated that the surrogate
recovery limits had been exceeded, and values were outside lower control limits.

On December 14, 2021, Monitoring wells (MWH-1 through MWH-5) were gauged and sampled. Wells MWH-3 and MWH-
4 were gauged as dry and were not sampled. Groundwater samples collected from MWH-1, MWH-2, and MWH-5 were
submitted to Pace National of Mount Juliet, Tennessee, to be analyzed for BTEXN, MTBE, TPH-GRO, and TPH-DRO using
EPA Methods 8260 and 8015. Groundwater gauging results detected groundwater in wells MWH-1, MWH-2 and off-site
well MWH-5 at depths ranging from 30.53 feet in MWH-5 to 34.02 feet in MWH-1. No groundwater was detected in on-
site wells MWH-3 and MWH-4. No LNAPL was detected in any of the wells gauged. Groundwater analytical results did
not detect COCs above ISLs in MWH-1 and MWH-5. Monitoring well MWH-2 contained COCs above ISLs for Benzene
(0.092 mg/L), TPH-GRO (2.03 mg/L), and TPH-DRO (7.45 mg/L). No COCs in MWH-2 exceeded Tier 1 Screening Criteria.

High Vacuum Dual Phase Extraction Event
Antea Group contracted with CalClean Inc. (CalClean) to perform a five-day HVDPE event extracting water and vapor
from well MWH-2 on June 24-29, 2024. Included as Attachment 1 is a HVDPE report prepared by CalClean which includes
a description of the equipment used to facilitate the work, operational parameters employed to extract water and vapor,
vapor monitoring data and calculated hydrocarbon mass removal rates and totals. Antea Group performed groundwater
monitoring of MWH-2 on June 24 prior to the HVDPE event and post HVDPE event on July 22 and October 25.
Groundwater monitoring data is included in Table 1 and laboratory reports are included as Attachment 2.

The applied vacuum during the extraction work ranged from a high of 23 inches of mercury (in. of Hg) on startup and
then stabilized at 21 in. of Hg on the second day of extraction and remained steady at 21 in. of Hg for the duration of the
5-day event. Average air flow from the extraction well was 41 standard cubic feet per minute (scfm). Hydrocarbon vapor
removal rates increased after system startup and peaked during the second day of extraction and then gradually
declined to the end of day 5. Cumulative removal over the 5 day event was 880 pounds of hydrocarbons based on
laboratory data of daily samples. A relatively small volume of groundwater was recovered during the extraction event
with a total of 330 gallons recovered over the 5-day event. The volume of water recovered was not significant enough to
utilize CalCleans water treatment system, so all the recovered water was placed in (6) 55-gallon drums and stored on-site
pending transport and disposal at E.T. Technologies. Waste disposal documents are included in Attachment 3.

Groundwater gauging and sampling was performed at well MWH-2 before extraction and after the completion of the 5-
day extraction event. On June 24 groundwater was gauged at a depth of 33.89 feet and the total well depth was
measured at 37.00 feet. A groundwater sample was collected from MWH-2 and submitted to Pace National of Mount
Juliet, Tennessee, to be analyzed for BTEXN, MTBE, TPH-GRO, and TPH-DRO using EPA Methods 8260 and 8015.
Groundwater analytical data is included as Table 1 and laboratory reports are included in Attachment 2. Analytical
results for MWH-2 indicated COCs above ISLs including Benzene (0.0812 mg/L), and TPH-DRO (7.67 mg/L). No COCs in
MWH-2 exceeded Tier 1 Screening Criteria. Post extraction gauging performed in July and October has not detected
groundwater in MWH-2, indicating the thin saturated zone has been dewatered by the extraction event and is very slow
to recover. Additional groundwater gauging of MWH-2 will be performed in 2025 to evaluate if groundwater will recover
in MWH-2 post extraction event.

Job Narrative
570-190094-1
Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary
Page unless otherwise noted under the individual analysis.Data qualifiers are applied to indicate exceptions.Noncompliant
quality control (QC)is further explained in narrative comments.
·Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted.In these situations,to
demonstrate precision and accuracy at a batch level,a LCS/LCSD may be performed,unless otherwise specified in the
method.
·Surrogate and/or isotope dilution analyte recoveries (if applicable)which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g.SDWA,NPDES)must comply with the associated agency requirements/permits.
Please note that one or more samples in the following analytical report have exceeded the laboratory recommended holding time
for tedlar bags (3 days).As per client-specific program requirements,associated qualifiers concerning holding time have been
removed.

Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification Summary
Page unless otherwise noted under the individual analysis.Data qualifiers are applied to indicate exceptions.Noncompliant
quality control (QC)is further explained in narrative comments.
·Matrix QC may not be reported if insufficient sample or site-specific QC samples were not submitted.In these situations,to
demonstrate precision and accuracy at a batch level,a LCS/LCSD may be performed,unless otherwise specified in the
method.
·Surrogate and/or isotope dilution analyte recoveries (if applicable)which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Regulated compliance samples (e.g.SDWA,NPDES)must comply with the associated agency requirements/permits.

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.
ND Not detected at the Reporting Limit (or MDL where applicable).
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.
J1 Surrogate recovery limits have been exceeded; values are outside upper control limits.

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.
ND Not detected at the Reporting Limit (or MDL where applicable).
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.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
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.
J4 The associated batch QC was outside the established quality control range for accuracy.
T8 Sample(s) received past/too close to holding time expiration.
