1.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC), on behalf of Circle K Stores, Inc. (Circle K), has
prepared a Groundwater Monitoring Report for The Pantry #3937, located in Charlotte,
Mecklenburg County, North Carolina. This report summarizes field activities conducted on May
30, 2023, in accordance with Pre-Approved Task Authorization (PATA-04), as approved May 10,
2023.

The results of the groundwater sampling event were as follows:

 Free phase petroleum was not detected in the monitoring well network;
 ATC gauged MW-01, MWV-01, MW-02, MWV-02, DW-02, MW-03, DW-03, MW-04,
MW-06, MW-08, MW-11 and MW-12;
 Groundwater flow during this sampling event was found to be to the northeast.
 One or more petroleum constituents exceeded the 15A NCAC 02L .0202 groundwater
quality standards (2L Standards) for groundwater in monitoring wells MW-1, MW-4,
MW-11, MW-12, MWV-1, MWV-2, DW-2 and DW-3;
 Dissolved benzene was detected at a concentration that exceeded the Gross
Contamination Levels (GCLs) of 5,000 µg/L in the groundwater sample collected from
monitoring well MW-11; and Tert-Butyl Alcohol was detected above its GCL in MW-12.

Concentrations of Benzene above the GCL remain in well MW-11, which was installed in response
to the August 2003 release from The Pantry UST system. However, the benzene concentration has
been generally decreasing since January 2017.

The presence of TBA in excess of the GCL in MW-12 suggests Methyl-Tert Butyl Ether (MTBE) is
breaking down in the subsurface.

ATC recommends quarterly groundwater sampling events of monitoring wells MW-1, MWV-1,
MWV-2, DW-2, MW-3, MW-4, MW-6, MW-8, MW-11, MW-12 and DW-3 to evaluate constituent
concentration trends.
2.0 SITE INFORMATION
2.1 Site Description
The site is situated in a commercial and residential area of Charlotte, North Carolina. The site
has an intermediate risk ranking of I150D, based on groundwater impact above the North
Carolina Department of Environmental Quality (NCDEQ) Gross Contaminant Levels (GCLs) for
groundwater.

The site is located at 2301 Beatties Ford Road in Charlotte, North Carolina. The property
consists of a single-story building, currently occupied by a tire sales retail outlet. The UST
Groundwater Monitoring Report June 30, 2023
Circle K 2723937 Page 2

system is currently not operating and the retail gasoline distribution system, which included three
10,000-gallon and one 4,000-gallon underground storage tanks (USTs), dispensing pumps, and
associated piping, were discontinued from service and removed from the site in September
2015.

The site is mostly covered by asphalt and concrete pavement with a wooded area behind the
store. Figure 1 shows the site location on a topographic map, and a site map showing the
locations of the monitoring wells and the previous UST system layout, is included as Figure 2.

The site has an intermediate risk ranking of I150D, based on groundwater impact above the
North Carolina Department of Environmental Quality (NCDEQ) Gross Contaminant Levels
(GCLs) for groundwater.

2.2 Site History
A petroleum release was discovered during the removal of five USTs in 1987. Phillips 66 initiated
an assessment program due to the discovery of subsurface petroleum impact by the City of
Charlotte. In 1995 free phase petroleum product was discovered in well MW-4, and monthly
bailing was initiated with reporting to the NCDEQ. In May 1996 a Comprehensive Site
Assessment (CSA) was submitted to the NCDEQ, characterizing the magnitude and extent of
impact to soils and groundwater from the release. In August 1996 a Corrective Action Plan (CAP)
was submitted, but was not approved by NCDEQ, to implement enhanced degradation of
dissolved petroleum constituents by injection of a calcium hydroxide compound. The NCDEQ
issued a Notice of Regulatory Requirements (NORR) on September 23, 1998, requesting a
revised CAP to address remediation of a high risk site due to the presence of a water supply well
within a 250 feet radius of the site. In November 1998, the water supply well was abandoned,
and the risk was reduced from high to intermediate based on the continued presence of free
phase petroleum product in well MW-4. As proposed in the April 1999 revised CAP, aggressive
fluid-vapor recovery (AFVR) technology has been used periodically from 1999 to present to
remove free phase petroleum product and reduce soil and groundwater impact concentrations
near well MW-4.

A second release was reported to the NCDEQ on August 8, 2003, in response to a vehicle
striking a product dispenser at the facility, which was then owned by Petro Express (Pantry No.
3937). As part of The Pantry’s assessment efforts, monitoring wells MW-10 through MW-16 and
DMW-1 through DMW-3 were installed at the site in October 2005. Free phase petroleum
product was identified under the dispensers during assessment activities, and free phase
petroleum product was identified in well MW-11.

An April 11, 2011, NORR indicated North Carolina UST Trust Fund availability for the site. AFVR
and groundwater monitoring events have been conducted at the direction of Phillips 66 at the site
since 2011. Pantry closed and removed the UST system (including tanks, product lines, and
dispensers) at the site in September 2015. ATC submitted a post-remedial monitoring report,
dated June 1, 2016, which indicated that groundwater impact in well MW-4 was below the GCLs.
Since impact was below the GCLs in assessment wells associated with the Phillips 66 incident
(including well MW-4) closure by a Notice of Residual Petroleum was requested.

On August 16, 2018, the site monitoring well network was gauged for fluid levels and
checked for the presence of free-phase petroleum product. Free phase petroleum was not

detected in the site monitoring well network. One or more petroleum constituents exceeded
the NC 2L standards for groundwater in monitoring wells MW-1, MW-4, MW-11, MW-12, MW-
14, MW-15, MW-16, MWV-1, MWV-2, and DW-3. Dissolved benzene was detected at a
concentration that exceeded the GCL of 5,000 µg/L in the groundwater sample collected from
monitoring well MW-11 (18,700 µg/L). Dissolved benzene was detected in wells MW-1, MW-
4, MW-12, and MWV-2 at concentrations that exceeded the 2L Standard of 1.0 ug/L.
ATC submitted a Groundwater Monitoring Report for the Phillips 66 Company (Phillips 66)
for the Former Conoco Store No. 33004-2 (Phillips 66 Risk Management [RM] No. 6227) on
February 14, 2019. The report indicated that one or more petroleum constituents exceeded the
NC 2L standards for groundwater in monitoring wells MW-1, MW-3, MW-4, MW-11, MW-12,
MW-14, MW-15, MW-16, MWV-1, MWV-2, and DW-3. Benzene was detected at a
concentration that exceeded the GCL of 5,000 µg/L in the groundwater sample collected from
monitoring well MW-11 at 18,700 µg/L. Benzene was detected in wells MW-1, MW-4, MW-
12, and MWV-2 at concentrations of 148 ug/L, 3,610 ug/L, 35.9J ug/L, and 1.2 ug/L,
respectively, which exceeded the 2L Standard of 1.0 ug/L.

On July 8, 2022, the site monitoring well network was gauged for fluid levels and checked for the
presence of free-phase petroleum product free phase petroleum was not detected in the site
monitoring well network. On July 8, 2022, groundwater samples were collected from groundwater
monitoring wells MW-1, MWV-1, MWV-2, DW-2, MW-3, MW-4, MW-6, MW-8, MW-11 and MW-
12. One or more petroleum constituents exceeded the NC 2L standards for groundwater in
monitoring wells MW-1, MW-4, MW-11, MW-12, and MWV-1. Dissolved benzene was detected at a
concentration that exceeded the GCL of 5,000 µg/L in the groundwater sample collected from
monitoring well MW-11. Dissolved benzene was detected in wells MW-1, and MW-4 at
concentrations that exceeded the 2L Standard of 1.0 ug/L.

On December 7, 2022, the site monitoring well network was gauged for fluid levels and
checked for the presence of free-phase petroleum product. ATC gauged MW-1, MWV-01,
MW-02, MWV-02, DW-02, MW-03, MW-04, MW-06, MW-08, MW-11 and MW-12. Monitoring
wells MW-14, MW-15, and MW-16 are located in the wooded area behind the former
convenience store and could not be located. On December 7, 2022, groundwater samples
were collected from groundwater monitoring wells MW-1, MWV-1, MW-2, MWV-2, MW-3,
MW-4, MW-6, MW-8, MW-11, MW-12, DW-2, and DW-3. One or more petroleum constituents
exceeded the 15A NCAC 02L .0202 groundwater quality standards (2L Standards) for
groundwater in monitoring wells MW-1, MW-4, MW-11, MW-12, MWV-1, MWV-2, DW-2 and
DW-3, Dissolved benzene was detected at a concentration that exceeded the Gross
Contamination Levels (GCLs) of 5,000 µg/L in the groundwater sample collected from
monitoring well MW-11; and Tert-Butyl Alcohol was detected above its GCL in MW-12.

2.3 Site Vicinity
The site is situated in a commercial and residential area of Charlotte, North Carolina. The
site is bordered to the north and west by a church; to the east by Beatties Ford Road with
Long and Son Mortuary Service beyond; and to the south by Keller Avenue with a bank
beyond.

2.4 Receptor Survey
Based on the Initial Abatement Action Report prepared by Environmental
Compliance Services dated December 17, 2015, there are no water supply wells
within 1,500 feet of the source area.
3.0 GROUNDWATER MONITORING
3.1 Groundwater Gauging
On May 30, 2023, the site monitoring well network was gauged for fluid levels and checked for
the presence of free-phase petroleum product. An oil/water interface probe was used to measure
the depth to water from the well top of casings. Groundwater elevations were then calculated based
on relative TOC elevations. Free phase petroleum product was not detected during the monitoring
event.

ATC gauged MW-1, MWV-01, MW-02, MWV-02, DW-02, MW-03, DW-03, MW-04, MW-06, MW-
08, MW-11 and MW-12. Monitoring wells MW-14, MW-15, and MW-16 are located in the wooded
area behind the former convenience store and could not be located.

Monitoring wells MW-5 and MW-7, could not be located and as a result, were not gauged. Well
MW-5 is believed to have been destroyed when the wooded area located behind the convenience
store was thinned out and graded in 2015. Construction that had occurred along a curb adjacent to
well MW-7 may have resulted in this well becoming damaged, buried, or destroyed. Well
construction details for the monitoring wells are summarized in Table 1. The locations of the
monitoring wells are shown in Figure 2, and the groundwater elevation data is summarized in Table
2. A groundwater elevation contour map, based on the May 2023 gauging data, is included as
Figure 3. Groundwater flow during this sampling event was found to be to the northeast. The
current groundwater flow may be attributed to the limited number of wells available for gauging.
3.2 Monitoring Well Sampling
On May 30, 2023, groundwater samples were collected from groundwater monitoring wells MW-
1, MWV-1, MW-2, MWV-2, MW-3, MW-4, MW-6, MW-8, MW-11, MW-12, DW-2, and DW-3.

A three-volume well purge was implemented prior to groundwater sample collection to ensure a
representative sample was collected. Upon completion of purging activities, water quality field
parameters were measured and are included in Table 2. The groundwater samples were placed in
laboratory-supplied, preserved containers, placed on ice; and shipped in accordance with chain-
of-custody protocol to Pace Analytical Services in Huntersville North Carolina (North Carolina
Lab Certification No. 12). The groundwater samples were analyzed by EPA Method 6200B for
volatile organic compounds (VOCs). The laboratory report and chain-of-custody record for the July
2022 sampling event is included in Appendix A.

3.3 Analytical Results
Groundwater analytical results are summarized in Table 3, and historical groundwater analytical
results are summarized in Table 4. A Groundwater Quality map is included as Figure 4. The
groundwater analytical results were compared to the 2L Standards and GCLs for groundwater.
Groundwater analytical results for the samples collected during the current sampling event
indicated the following:

 Free phase petroleum was not detected in the monitoring well network;
 One or more petroleum constituents exceeded the 2L Standards for groundwater in
monitoring wells MW-1, MW-4, MW-11, MW-12, MWV-1, MWV-2, DW-2 and DW-3;
 Dissolved benzene was detected at a concentration that exceeded the GCLs of 5,000 µg/L
in the groundwater sample collected from monitoring well MW-11; and Tert-Butyl Alcohol
was detected above its GCL in MW-12.
4.0 CONCLUSIONS AND RECOMMENDATIONS
ATC conducted a groundwater monitoring event in May 2023. Analytical results indicated:

 Free phase petroleum was not detected in the site monitoring well network;
 ATC gauged MW-1, MWV-01, MW-02, MWV-02, DW-02, MW-03, DW-03, MW-04,
MW-06, MW-08, MW-11, MW-12 and DW-3;
 Groundwater flow during this sampling event was found to be to the northeast.
 One or more petroleum constituents exceeded the 2L Standards for groundwater in
monitoring wells MW-1, MW-4, MW-11, MW-12, MWV-1, MWV-2, DW-2 and DW-3;
 Dissolved benzene was detected at a concentration that exceeded the GCLs of 5,000 µg/L
in the groundwater sample collected from monitoring well MW-11; and Tert-Butyl Alcohol
(TBA) was detected above its GCL of 10,000 ug/L in MW-12.

Concentrations of Benzene above the GCL remain in well MW-11, which was installed in response
to the August 2003 release from The Pantry UST system. However, the benzene concentration has
been generally decreasing since January 2017.

The presence of TBA in excess of the GCL in MW-12 suggests Methyl-Tert Butyl Ether (MTBE) is
breaking down in the subsurface.

ATC recommends quarterly groundwater sampling events of monitoring wells MW-1, MWV-1,
MWV-2, DW-2, MW-3, MW-4, MW-6, MW-8, MW-11, MW-12 and DW-3 to evaluate constituent
concentration trends.

5.0 REPORT LIMITATIONS
This investigation is intended to be a non-biased assessment of on-site environmental conditions
proximate to the location of the former and/or current UST system. Subsurface investigative and
remedial methodologies were performed in general accordance with applicable state and federal
regulatory requirements. The information presented in this report is based upon site-specific
observations, generally accepted geological and environmental consulting practices, and
analytical results for environmental samples collected at the time the field investigation was
performed. The data presented in this report are believed to represent subsurface conditions at
the facility; however, data may not be completely representative of subsurface conditions at
every location. ATC assumes no liability arising from environmental impact to, or from, the site,
regardless of the date of impact occurrence or findings.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
Sample was diluted due to the presence of high levels of non-target analytes or other matrix interference.D3
This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be
considered an estimated value.IH
Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated
samples may be biased high.L1
Matrix spike recovery and/or matrix spike duplicate recovery was outside laboratory control limits.M0
Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1
The EPA or method required sample preservation degrades this compound, therefore acceptable recoveries may not be
achieved in sample matrix spikes.P5
RPD value was outside control limits.R1
