1.0 INTRODUCTION
ATC Associates of North Carolina, P.C. (ATC), on behalf of Circle K Stores, Inc. (Circle K), is
submitting this monitoring report for the Circle K Store #2723471 facility located at 4940 U.S.
Highway 264 West, Wilson, Wilson County, North Carolina (Incident #33892). Currently, the
site is an active convenience store and retail fuel outlet. A site topographic map is presented as
Figure 1 and site map is presented as Figure 2. UST owner/operator and system information is
included in Table 1.
2.0 EXECUTIVE SUMMARY
The presence of petroleum-related impacts to soil, above Soil-to-Groundwater Maximum
Contaminant Concentrations (STGW-MSCCs), were identified in soil samples SD-10 and
SK-30. Soil sample SD-10 was collected near the gasoline dispenser islands and soil sample
SK-30 was located near the kerosene product line. It should be noted petroleum-related impacts
to soil were not identified above the applicable Residential MSCCs. Horizontally, the extent of
impacted soil is in the vicinity of the gasoline dispenser area and the kerosene product line.
Vertically, impacted soil extends to the water table. Historical soil analytical data along with a
map depicting the locations of the soil samples are provided in Appendix A.
Overall, a dissolved isopropylbenzene concentration in the groundwater sample collected from
monitoring well MW-3 has been identified above applicable standards. As a consequence of the
assessment activities conducted at the facility, the horizontal and vertical extents of dissolved
petroleum hydrocarbon concentrations have been reasonably defined and are limited to the
vicinity of monitoring well MW-3. Based on the most current groundwater analytical data, it
appears dissolved contaminant compound concentrations in monitoring wells MW-3 and DW-1
continue to decrease at the site. A geologic transect and geologic cross-sections with the March
2015 analytical data are included in Appendix B.
3.0 SITE HISTORY
On February 17, 2009, the North Carolina Department of Environmental Quality (NCDEQ)
conducted a compliance inspection at the facility. On February 18, 2009, NCDEQ issued a
Notice of Violation (NOV) for the site as the premium gasoline underground storage tank (UST)
Monitoring Report January 13, 2021
NCDEQ Incident No. 33892
Page 2
was not in compliance with current NC UST regulations. In the NOV, the following violations
were noted: premium UST did not have any spill protection, failure to report a suspected release,
and failure to investigate a suspected release.
In response to the NOV, ATC personnel initiated site check activities. As part of the site check
activities, a soil boring (SB-1) was collected near the premium gasoline UST fill port. The soil
analytical data did not detect total petroleum hydrocarbons (TPH) – gasoline range organics
(GRO) above the established NCDEQ Action Level of 10 milligrams per kilogram (mg/kg). A
Site Check Report was submitted to NCDEQ on July 9, 2009.
In response to the findings presented in the Site Check Report, NCDEQ issued a Notice of
Regulatory Requirements (NORR) on November 16, 2009, requesting a site check addendum.
On January 20, 2010, ATC supervised the installation of monitoring well MW-1. Subsequently,
a groundwater sample was collected from well MW-1. Groundwater analytical results of the
groundwater sample collected from monitoring well MW-1 indicated dissolved target compound
concentrations exceeding established 2L Standards.
On September 8, 2010, based on the laboratory analytical results of the groundwater sample,
NCDEQ issued a Notice of Regulatory Requirements (NORR) requesting a limited site check in
the area of the diesel and kerosene UST systems. ATC advanced forty-seven soil borings at
various locations around the site. Laboratory analytical results of the soil samples detected
TPH-diesel range organics (DRO) above the established action level in several of the soil
samples. A second monitoring well, MW-2, was installed at the site adjacent to the diesel
dispensers. Laboratory analytical results of the groundwater sample collected from monitoring
well MW-2 did not detect dissolved target compound concentrations above established 2L
Standards. A receptor survey was completed during this time and two potable water supply wells
(one active and one inactive) were identified within 1,500 feet of the site. A Site Check and
Receptor Survey Report was submitted to NCDEQ on January 3, 2011.
During May 2011, The Pantry installed spill containment sumps at eight of the twelve gasoline
dispenser islands. During these activities, petroleum staining and odor was detected in the soil.
Monitoring Report January 13, 2021
NCDEQ Incident No. 33892
Page 3
Between May and June 2011, as part of initial abatement activities, approximately 35.89 tons of
petroleum-impacted soil was excavated from the site for off-site disposal. Laboratory analytical
results of soil samples detected TPH-DRO and TPH-GRO above the action level for several of
the soil samples.
During February 2013, The Pantry conducted gasoline piping replacement at six of the gasoline
dispensers located on the eastern portion of the property. During these activities, petroleum
staining and odor was detected in the soil. As part of initial abatement activities, approximately
200 tons of petroleum-impacted soil was excavated from the site for off-site disposal.
Laboratory analytical results of soil samples detected TPH-GRO and TPH-GRO above the action
level for several of the soil samples. Based on the soil analytical results, a Phase I LSA was
initiated.
As part of LSA activities, three monitoring wells were installed and subsequently sampled. Free
product was measured in monitoring well MW-3 at a thickness of 0.58 feet. Laboratory
analytical results of the groundwater samples collected from the remaining wells detected
dissolved target compound concentrations in exceedance of 2L Standards. ATC also conducted a
receptor survey which identified one water supply well within 1,000 feet of the site. The well,
PW-1, is located approximately 550 feet southwest of the site and is used for drinking purposes.
Based on a “high risk” classification of the site, ATC recommended the completion of a
Comprehensive Site Assessment (CSA).
CSA activities were conducted at the site in February 2015. During CSA activities, six
monitoring wells were advanced to delineate impacted groundwater at the site, a comprehensive
sampling event was conducted, and slug testing was performed to determine aquifer
characteristics. Based on laboratory analytical results, dissolved target compound concentrations
exceeding 2L Standards were observed in several monitoring wells. A CSA Report was
submitted to NCDEQ on May 8, 2015.
On August 3, 2015, NCDEQ issued a NORR for deficiencies noted in the CSA report: soil
contaminated was not delineated using risk-based analytical parameters and the vertical
Monitoring Report January 13, 2021
NCDEQ Incident No. 33892
Page 4
delineation of petroleum-impacted groundwater above 2L Standards was not completed. An
Initial Pre-Corrective Action Plan (CAP) Monitoring Report was submitted to NCDEQ on
February 17, 2016.
Since February 2016, Aggressive Fluid Vapor Recovery (AFVR) events have been performed on
monitoring well MW-3 to address the presence of free product at the site and semi-annual
groundwater sampling events have been performed. Biosocks have been installed and
maintained in select wells to assist with natural attenuation activities.
A site check was performed at the site during September 2019 to address the source of the free
product in monitoring well MW-3. A Site Check Report was submitted to NCDEQ on
November 4, 2019.
The site and surrounding area is classified by Wilson County as Business. Properties beyond the
site are mainly gas stations, restaurants, and hotels. Adjacent property owner information is
included as Table 2. Figure 3 presents a map depicting the surrounding area.
During previous assessment activities, two water supply wells were identified within 1,500 feet
of the subject facility. One water supply well, PW-1, is located approximately 550 feet
southwest of the site and is used for potable purposes. The second water supply well is located
1,500 feet southwest of the site and is currently not in use. Water supply information is
summarized in Table 3 and depicted on Figure 3.
Public water supplies in the area are provided by the City of Wilson. The City of Wilson obtains
its water from two sources, Contentnea Creek and Toisnot Reservoir. Contentnea Creek water is
stored in Buckhorn Lake and the downstream Wiggins Mill Reservoir. The Toisnot Reservoir is
supplied by the upgradient Lake Wilson.
This report documents the results of a groundwater sampling event.

Free product recovery activities were not conducted during this report period.
5.0 GROUNDWATER MONITORING
5.1 Geology and Hydrogeology
According to the Geologic Map of North Carolina (1985), the site is located within the Coastal
Plain Physiographic Region of North Carolina. More specifically, the site is underlain by the
Yorktown Formation and Duplin Formation, undivided. The Yorktown Formation is
characterized by fossiliferous clay with varying amounts of fine grained, bluish gray, shell
material concentrated in lenses. The Duplin Formation is characterized by shelly, medium to
coarse grained sand, sandy marl, and limestone and is also bluish gray. It appears the surficial
aquifer extends to a depth of 20 feet below ground surface (bgs), the Yorktown aquifer extended
approximately 20 to 40 feet bgs, and the Upper Cape Fear aquifer extends from 40 to 80 feet bgs.
According to the Soil Survey of Wilson County, North Carolina, prepared by the United States
Department of Agriculture Soil Conservation Service, the site lies within the Norfolk loamy sand
complex, the Rains sandy loam complex, and the Tatus loam complex. The Norfolk loamy sand
complex is classified by 2 to 6 percent slopes, well drained, moderately high to high capacity to
transmit water, and originates from loamy marine deposits. The Rains sandy loam complex is
classified by 0 to 2 percent slopes, poorly drained, moderately high to high capacity to transmit
water, and originates from loamy marine deposits. Finally, the Tatum loam complex is classified
by 2 to 6 percent slopes, well drained, very low to high capacity to transmit water, and originates
from residuum of weathered metavolcanics and/or argillite.
Groundwater movement in the upper portion of the surficial aquifer appears to flow in a
northeastern direction across the site. Based on available groundwater data, it appears there is a
slight vertical head difference between the shallow and deep monitoring well, which suggest that
a vertical exchange of groundwater may occur between the upper and lower portions of the
surficial aquifer.
Monitoring Report January 13, 2021
NCDEQ Incident No. 33892

As part of the CSA, ATC performed a slug test using monitoring wells MW-7, MW-9, and
DW-1. Based on the slug test results, the average hydraulic conductivity at the site was
calculated at approximately 0.8261 feet per day.
5.2 Biosock Installation and Maintenance
Biosocks were removed from wells MW-1 and DW-1 during the groundwater sampling event.
New biosocks were not installed.
5.3 Groundwater Elevations
On October 21, 2020, ATC collected static water level measurements from monitoring wells
MW-1, MW-2, MW-3, MW-5, MW-6, and DW-1. Depths to water measurements were
collected using an electronic oil/water interface probe. The groundwater depths were converted to
relative elevations using an assumed datum of 100 feet relative to an arbitrary on-site benchmark.
Monitoring well construction details are included in Table 4. Current and historical groundwater
elevation data are included in Table 5. A groundwater elevation contour map based on the October
2020 static water level data is included as Figure 4. Based on the recent groundwater level
measurements, groundwater flow appears to be toward the north/northwest. Historical groundwater
flow maps are provided in Appendix C.
5.4 Groundwater Analytical Results
On October 21, 2020, groundwater samples were collected from monitoring wells MW-1,
MW-2, MW-3, MW-5, MW-6, and DW-1. Groundwater samples were collected into
laboratory-approved containers, packed in ice and delivered under chain-of-custody to SGS
North America (SGS) in Scott, Louisiana, for analyses. Groundwater samples were analyzed for
volatile organic compounds (VOCs) via EPA Method 6200B including methyl tertiary-butyl
ether (MTBE) and isopropyl ether (IPE). A summary of the recent groundwater analytical data is
presented in Table 6 and a historical summary of groundwater analytical data is presented in
Table 7. Select natural attenuation measurements are provided in Table 8.
Monitoring Report January 13, 2021
NCDEQ Incident No. 33892
Page 7
The laboratory analytical results from the October 2020 sampling event detected a dissolved
isopropylbenzene concentration above its established 2B Surface Water Standard times ten in the
groundwater sample collected from monitoring well MW-3.
Other dissolved target compound concentrations were detected above laboratory method
detection limits (MDLs) in the groundwater samples collected from monitoring wells MW-1,
MW-2, MW-3, MW-5, and DW-1; however, these concentrations were below the established ten
times the 2B Surface Water Standards. It should be noted some of the dissolved target
compound concentrations were detected above established 2L Standards in the groundwater
samples collected from monitoring wells MW-1, MW-2, MW-3, and DW-1.
Dissolved contaminants of concern, exceeding 2L Standards, are included as Figure 5. It appears
dissolved target compound concentrations in the groundwater samples from the monitoring wells
being sampled are decreasing through time. A groundwater concentration trend plot for dissolved
MTBE concentrations versus depth to water for monitoring well DW-1 is included as Figure 6. A
copy of the laboratory analytical report is included as Appendix D.
5.5 Water Supply Well Sampling
On October 21, 2020, ATC personnel sampled the active water supply well (labeled PW-1)
located at 4957 Raleigh Road Parkway. The approximate location of the water supply well is
provided in Figure 3. Prior to the collection of the sample, a spigot located at the front of the
residence was allowed to run for approximately 10 minutes. The sample was collected into
laboratory-approved containers, packed in ice and delivered under chain-of-custody to SGS in
Scott, Louisiana, and submitted for chemical analysis by EPA Method 6200B. The laboratory
analytical results did not detect target compound concentrations above the laboratory method
detection limits (MDLs). Water supply well analytical data is included in Table 9. A copy of the
laboratory analytical report is included in Appendix D.
6.0 MONITORING PLAN AND SCHEDULE
The next semi-annual groundwater sample event will be scheduled for April 2021.
Monitoring Report January 13, 2021
NCDEQ Incident No. 33892

7.0 CONCLUSIONS
ATC has performed a groundwater sampling event at the Circle K Store #2723471 located in
Wilson, North Carolina. Based on field activities, observations, and groundwater analytical
results, ATC concludes the following:
Depth to groundwater measurements ranged from 4.24 feet to 8.80 feet below ground surface
MW-3 and MW-6, respectively. Based on information obtained during the October 2020
sampling event, groundwater appears to flow across the site in a north/northwesterly
direction;
Free phase product was not detected in monitoring well MW-3 during the report period;
Biosocks were removed from monitoring wells MW-1 and DW-1 and new biosocks were not
installed;
Based on historical soil analytical data, it appears soil above Residential MSCCs is not
present at the facility. Horizontally, the extent of impacted soil is in the vicinity of the
gasoline dispenser area and the kerosene product line. Vertically, impacted soil extends to
the water table;
Laboratory analytical results of a groundwater sample collected from water supply well PW-1
did not detect dissolved target compound concentrations above laboratory method detection
limits;
The laboratory analytical results from the October 2020 sampling event detected a dissolved
isopropylbenzene concentration above its established 2B Surface Water Standard times ten in
the groundwater sample collected from monitoring well MW-3;
Other dissolved target compound concentrations were detected at the site above 2L Standards
but below ten times 2B Standards; and,
Based on the most recent groundwater analytical data, it is appears dissolved target compound
concentrations continue to decrease at the site.
The next semi-annual groundwater sample event will be scheduled for April 2021.
