EXECUTIVE SUMMARY
ATC has completed an Annual Monitoring Report at the Circle K Store 2720828, located at 10329
Park Road, in Charlotte, Mecklenburg County, North Carolina. Assessment activities conducted
from October through December 2023 included the installation of one Type III well (TW-2)
monitoring well, two air sparge wells (AS-1 and AS-2), and two recovery wells (RW-2 and RW-3).
Two 96-hour Mobile Multi-Phase Extraction (MMPE) events, a groundwater sampling event, and
Top of Casing elevation (TOC) measurements in accordance with the Pre-Approval Task
Authorization (PATA) number 40819-07, approved on September 5, 2023.
The site is currently an active convenience store and gas station with petroleum retail and
operates two 10,000-gallon gasoline underground storage tanks (USTs) and one 10,000-gallon
diesel UST. A release from the UST system was reported on May 4, 2018. Water supply wells
have not been identified within 1,500-feet of the property. ATC has conducted multiple phases of
assessment and remediation activities since that time.
Results of previous and current assessment activities indicate the following:
The nearest surface water body is an unnamed tributary of McMullen Creek, located
approximately 1,000 feet to the east of the source area.
Light nonaqueous phase liquid (LNAPL) is present on site.
Atlas supervised the installation of one Type III well (TW-2) monitoring well, two air sparge
wells (AS-1 and AS-2), and two recovery wells (RW-2 and RW-3).
On October 30, 2023 and November 6, 2023, two 96-hour MMPE events were conducted
using MW-5, MW-8, MW-10, RW-1, RW-2, and AS-2 as target extraction wells in the first
MMPE event and MW-1, MW-5, MW-9, MW-10, RW-1, and RW-3 in the subsequent
MMPE event.
o The October 2023 MMPE event generated approximately 5,468 gallons of fluid,
including 30 gallons of free -phase LNAPL, and recovered approximately 52.95
gallons of volatile organic compounds (VOCs) as vapor emissions.
o The November 2023 MMPE event generated approximately 6,268 gallons of fluid,
including 11 gallons of free-phase LNAPL, and recovered approximately 45.17
gallons of volatile organic compounds (VOCs) as vapor emissions.
On December 7, 2023, monitoring wells MW-1 through MW-14, TW-1, TW-2, RW-1 RW-
2, and AS-1 were gauged for liquid levels and total well depths. LNAPL thickness was
measured in wells MW-1 at 0.20 feet, MW-5 at 0.03 feet, MW-7 at 0.58 feet, MW-8 at 0.40
feet, MW-9 at 0.60 feet, MW-10 at 0.49 feet, MW-11 at 3.00 feet, MW-13 at 0.01 feet, RW-
1 at 0.47 feet, RW-2 at 0.02 feet, RW-3 at 0.69 feet.
On December 7 and 8, 2023, ATC sampled monitoring wells MW-2, MW-3, MW-4, MW-
6, MW-12, MW-14, TW-1, TW-2, AS-1, and AS-2. Monitoring wells MW-1, MW-5, MW-7,
MW-8, MW-9, MW-10, MW-11, MW-13, RW-1, RW-2, and RW-3 were not sampled due
to the presence of measurable LNAPL.
Dry-cleaning solvent tetrachlorethylene (PCE) was detected above the North Carolina 2L
Groundwater Quality Standards as defined in Title 15A, NCAC, Subchapter 2L, Part .0202
(2L Standard) in eight monitoring wells (AS-2, MW-2, MW-3, MW-6, MW-12, MW-14, TW-
1, and TW-2), and PCE was detected with levels above the North Carolina Gross
Corrective Action Performance Report
Circle K 2720828
Page v
Contamination Standards in MW-3. Trichloroethylene (TCE) was detected above the 2L
Standards in seven wells (AS-2, MW-2, MW-3, MW-12, MW-14, TW-1, and TW-2).
Monitoring wells AS-1, AS-2, MW-2, MW-3, MW-6, MW-12, MW-14, TW-1, and TW-2
contained multiple petroleum constituents in excess of the 2L Standards.
Petroleum constituents were not detected above the laboratory detection limits in well
MW-4.
TCE and PCE are chemicals typically detected in solvent releases. ATC does not have any
evidence of a solvent release on the Circle K Store 2720828 property. Therefore, any TCE or
PCE detected in the groundwater samples collected at the Circle K Store 2720828 are assumed
to not be related to the UST release.
Dissolved-phase petroleum contamination in groundwater has not been horizontally delineated,
with the exception of the western portion of the site as indicated by the analytical results of MW-
4.
Based on the findings of the current and previous site activities, ATC recommends the following:
Conduct an MMPE/AS event, the first utilizing MW-1, MW-8, MW-9, MW-11,and
RW-3 as target extraction wells.
Complete a comprehensive groundwater monitoring event approximately 30 days
after the MMPE/AS events and report findings in a Corrective Action Performance
Report.

1.0 INTRODUCTION
This Corrective Action Performance Report presents a summary of activities conducted at the site
by ATC Associates of North Carolina, PC (ATC) from October through December 2023. The
Circle K 2720828 facility is located at 10329 Park Road, Charlotte, Mecklenburg County, North
Carolina (site). Summaries of UST system and owner/operator information are included in Table
1 and Table 2. A site vicinity map with topographic features is included as Figure 1.
The site is currently operated by Circle K Stores, Inc. as a convenience store and gas station with
petroleum retail. During field activities, the site was observed to be developed with one single-
story building, three active underground storage tanks (USTs), and one fuel canopy with three
dispenser islands. Site features are illustrated on Figure 2.
These assessment activities were conducted in accordance with the Pre-Approval Task
Authorization (PATA) number 40819-07, approved on September 5, 2023.
2.0 SITE CHARACTERIZATION AND HISTORY
The site is currently utilized as an active convenience store and gas station. The majority of the
site is covered by impervious surfacing (i.e. buildings, asphalt, concrete, etc.). Adjoining to the
north is Park Road and medical offices, with Park Cedar Drive and a CVS store bounding the
property toward the east. To the south and west is a commercial shopping center. Adjoining
property owners are summarized in Table 3.
The UST system consists of two 10,000-gallon gasoline USTs and one 10,000-gallon diesel UST,
with three associated dispensing islands. According to information obtained from the NCDEQ
“UST Registry Database”, the USTs were installed in 1989.
The site is at an elevation of approximately 608-feet above mean sea level. The general
topography of the site is relatively flat. Surface drainage generally follows the grade of the site
and ultimately discharges to a storm sewer system and/or swales.
2.1 Receptor Survey
During previous assessment activities, ATC conducted a receptor survey to identify water supply
wells, surface water bodies, and other potential receptors within 1,500-feet of the source area.
The receptor survey included reviewing a United States Geological Survey (USGS) 7.5-Minute
Quadrangle Topographic Map (Figure 1) to identify possible surface water bodies in the vicinity,
issuing questionnaires to property owners within 500 feet of the source area, and conducing a
vehicular reconnaissance. During the receptor survey, ATC did not identify water supply wells
within 1,500 feet of the property.
According to the topographic map, the nearest surface water body is an unnamed tributary of
McMullen Creek, located approximately 1,000 feet to the east of the source area, and an unnamed
tributary of Little Sugar Creek was depicted approximately 1,700 feet to the northwest of the
source area. However, these surface water bodies were not identified during the visual

reconnaissance. Results of the receptor survey and vehicular reconnaissance are summarized in
Table 4.
2.2 Site History
In April 2018, ATC completed limited site check activities associated with the Unleaded and Diesel
spill buckets, which reportedly failed hydrostatic testing and were suspected to have contributed
to a release at the site. Soil sampling associated with the Diesel spill bucket indicated Total
Petroleum Hydrocarbons - Gasoline Range Organics (TPH-GRO) and TPH - Diesel Range
Organics (DRO) were detected at concentrations in excess of the applicable NCDEQ Action
Levels. A release was reported associated with the diesel fuel spill bucket.
In July 2018, ATC completed a Phase I Limited Site Assessment (LSA), and installed monitoring
well, MW-1, adjacent to the diesel spill bucket. When ATC returned to the site to collect a
groundwater sample, light non-aqueous phase liquid (LNAPL) was measured at a thickness of
6.45 feet, and no groundwater sample was collected. Depth to water was measured to be
approximately 28 feet below ground surface (ft-bgs).
ATC completed a Comprehensive Site Assessment (CSA) and installed six monitoring wells (MW-
2 through MW-6, and TW-1) between November 19, 2018, and January 24, 2019. LNAPL was
measured in both MW-1 and MW-5. Soil samples collected from the monitoring well borings
indicated that soil contamination had been delineated in the horizontal direction and that vertical
contamination extended to the groundwater table. Groundwater samples collected during the CSA
indicated multiple petroleum constituents in excess of the North Carolina 2L Groundwater Quality
Standards as defined in Title 15A, NCAC, Subchapter 2L, Part .0202 (2L Standard). Additionally,
dry cleaner solvent constituents were reported above the applicable Gross Contamination Level
(GCL) and are presumed to be associated with an unrelated release in the vicinity of the site.
In November 2019, ATC conducted a 96-hour Mobile Multi-Phase Extraction (MMPE) event using
monitoring wells MW-1 and MW-5 as target extraction wells. Approximately 5,348 gallons of total
fluids, including 107 gallons of free-phase LNAPL, and approximately 340.7 gallons of VOCs as
vapor were removed from the subsurface. Approximately 30 days after the MMPE event, ATC
conducted a groundwater sampling event. LNAPL was measured in monitoring wells MW-1 and
MW-5. The laboratory analysis indicated Tetrachloroethylene (PCE) was detected in well MW-3
in excess of the GCL. Multiple other petroleum constituents were detected at concentrations
exceeding 2L Standards in monitoring wells MW-2, MW-3, MW-6, and TW-1.
In September 2020, ATC conducted a MMPE event, which generated approximately 5,417
gallons of fluids, including 92 gallons of free-phase LNAPL, and recovered approximately 402.74
gallons of VOCs as vapor. In October 2020, ATC conducted a subsequent groundwater sampling
event. LNAPL was measured in monitoring wells MW-1 and MW-5 at a thickness of 0.94 feet and
0.37 feet, respectively. PCE was detected above the GCL in monitoring well MW-3. Monitoring
wells MW-2, MW-3, MW-6, and TW-1 contained multiple VOCs above 2L Standards. ATC
recommended installing shallow monitoring wells to the north and east of the source area and a
recovery well in the vicinity of the UST pit and using the recovery well during a MMPE.
In March 2021, ATC supervised the installation of monitoring wells MW-7, MW-8, and recovery
well RW-1, to evaluate the contaminant plume to the northeast of the source area and assist in
recovering LNAPL and impacted groundwater during extraction events. Following installation of
the monitoring wells, ATC conducted an MMPE event using monitoring wells MW-1, MW-5, and
Corrective Action Performance Report
Circle K 2720828
Page 9
RW-1 as target extraction wells. The MMPE event recovered approximately total 10,000 gallons
of fluids, including 67 gallons of free-phase LNAPL, and 187.46 gallons as vapor. During the
subsequent groundwater monitoring event, LNAPL was measured in wells MW-1, MW-5, MW-8,
and RW-1 ranging from 1.71 feet to 0.43 feet in thickness. PCE was detected above the GCL in
monitoring well MW-3. Monitoring wells MW-2, MW-3, MW-6, MW-7, and TW-1 contained multiple
petroleum constituents at concentrations over 2L Standards. Based on these results, ATC
recommended the installation of three additional shallow monitoring wells and conducting a
MMPE event.
In November 2021, ATC supervised the installation of monitoring wells MW-9, MW-10, and MW-
11 to evaluate the contaminant plume to the northeast and east of the source area and assist in
recovering LNAPL and impacted groundwater during extraction events.
Following installation of the monitoring wells, on December 6, 2021, ATC conducted an MMPE
event using monitoring wells MW-1, MW-5, MW-8 through MW-11, and RW-1 as target extraction
wells. The MMPE event recovered approximately total 5,456 gallons of fluids, including 21 gallons
of free-phase LNAPL, and 129.0 gallons as vapor.
On January 4, 2022, ATC conducted a subsequent groundwater sampling event to evaluate the
effectiveness of the MMPE event. Monitoring wells MW-1 through MW-11,TW-1,and RW-1 were
gauged for liquid levels and total well depths prior to sampling activities using an oil/water interface
probe (IP). LNAPL thickness was measured in wells MW-1 at 0.54feet, MW-5 at 2.01 feet, MW-7
at 2.39 feet. MW-8 at 0.43 feet, MW-10 at 0.37 feet, MW-11 at 0.35 feet, and RW-1 at 0.17 feet.
PCE was detected in well MW-3 in excess of the GCL, along with TCE, in MW-2, MW-3, and TW-
1. Monitoring wells MW-2, MW-6, MW-9, and TW-1 contained multiple petroleum constituents at
concentrations over 2L Standards. Based on these results, ATC recommended a tank and line
tightness testing for the entire system and the installation of three additional shallow monitoring
wells and conducting a MMPE event.
From November 2022 to February 2023 ATC conducted assessment activities which included the
installation of three Type II monitoring wells, a 96-hour MMPE event, a groundwater sampling
event, and water level gauging activities. Monitoring wells MW-12, MW-13, and MW-14 were
installed to evaluate the extents of LNAPL and GCL exceedances in the groundwater.
Prior to the MMPE event, LNAPL was measured in wells MW-1 (3.89 feet) and MW-5 (1.56 feet)
prior to starting the system. Approximately 4980-gallons of fluids were recovered from wells MW-
1, MW-5, and RW-1. At least 102 gallons of free-phase LNAPL was measured in the tanker at
shut down, with approximately 131.71 gallons of VOCs removed as vapor. The MMPE events
appear to be an effective method of LNAPL recovery. During the subsequent groundwater
monitoring event and gauging activities, LNAPL was measured in MW-1 (2.41 feet), in MW-5
(0.51 feet), in MW-8 (0.43 feet), and in RW-1 (0.86 feet). LNAPL thickness in wells MW-1 and
MW-5 has decreased significantly since detected in 2018. However, the presence of LNAPL in
MW-8 indicates the extent of LNAPL has not been fully delineated to the north-northeast of the
source area.
Groundwater samples collected after the MMPE event indicated PCE was detected in well MW-
3 in excess of the GCL, and over the 2L Standard, along with TCE, in MW-2, MW-3, MW-7, and
Corrective Action Performance Report

TW-1. TCE and PCE are chemicals typically detected in solvent releases. ATC does not have
any evidence of a solvent release on the Circle K Store 2720828 property. Therefore, any TCE
or PCE detected in the groundwater samples collected at the Circle K Store 2720828 are assumed
to not be related to the UST release. Multiple other petroleum constituents were detected at
concentrations exceeding 2L Standards in monitoring wells MW-2, MW-3, MW-6, MW-7, and TW-
1. Petroleum constituents were not detected in well MW-4.
3.0 GEOLOGIC FRAMEWORK
3.1 Site and Regional Geology
According to the 1985 “Geologic Map of North Carolina”, the site lies in the Charlotte Belt of the
Piedmont Physiographic Province of North Carolina, which is composed of foliated to massive
granitic rock characterized by metagabbro, metadiorite, and mafic plutonic-volcanic complexes.
The unit is locally referred to as Metamorphosed Mafic Rock. The shallow subsurface in most areas
of the Piedmont contains residual soil overburden, including structure-free residuum, saprolite, and
partially weathered rock (PWR) that derive from in-place weathering of the crystalline bedrock.
Occasional areas containing recent deposits of alluvium in the uppermost subsurface are found near
streams and rivers. Saprolite and PWR typically contain some relict structures from the original rock
material.
The soils are typically saprolitic and are formed by in-place weathering of bedrock and the
subsequent breakdown of associated minerals. Surficial soils observed at the site by ATC during
drilling activities reportedly consisted of silty clay with sand to depths of approximately 10-feet below
grade. Partially weathered rock with dense silty sand was encountered from depths of approximately
10 to 38-feet below grade. Competent rock was encountered from approximately 38-feet to 60-feet
below grade, with water-producing fractures encountered between approximately 50 to 60-feet below
grade.
3.2 Site and Regional Hydrogeology
The shallow aquifer occurrence varies in depth from ground surface at springs, creeks, and rivers
to as deep as 50-feet or more beneath upland surfaces in some parts of the Piedmont. Water in
the alluvium or unconsolidated residual material, including saprolite and PWR, usually behaves
as an unconfined aquifer, or water table, and will yield water with head elevation equivalent to the
first elevation where water was encountered. Permeability varies with lithology and is typically
relatively low in residual soils, with higher permeability in saprolite or PWR due to relict rock
texture and variable susceptibility to weathering exhibited by different minerals in the rock.
Groundwater flow in residual soils or alluvium is usually in rough concurrence with local
topographic conditions and is toward local drainage features.
Depth to groundwater in site monitoring wells with no history of LNAPL has ranged from
approximately 13 to 26 ft-bgs. Depth to groundwater in the source area has ranged from
approximately 15.50 to 34.5 ft-bgs and is displaced by the presence of LNAPL ranging in
thickness from 0.12 feet to 14.15 feet, not including measurements recorded at the conclusion of
MMPE events.
Corrective Action Performance Report
Circle K 2720828
Page 11
The bedrock fractures or other planar features of the Piedmont Physiographic Province generally
constitute the bedrock aquifer, with the surrounding rock material being effectively impermeable.
Along with fractures, contacts between rock bodies probably constitute zones of significant
groundwater occurrence in the bedrock. The surrounding material and overlying residuum tend
to make the bedrock aquifer a semi-confined aquifer. That is, the overlying water and soil weight
normally results in pressure that causes water in a borehole, which intersects a fracture or other
feature, to rise above the elevation of the fracture or feature. Modern water supply wells in the
Piedmont, likely including any which may be in the site vicinity, are typically installed with a surface
casing through the unconsolidated material, and an open borehole into the bedrock where water-
bearing fractures are encountered.
3.3 Hydrogeologic Investigation
During the CSA, three rising-head slug tests were performed in Type II monitoring wells MW-2
and MW-3, and Type III monitoring well TW-1. The hydraulic conductivity in the shallow aquifer
zone was calculated to range from 0.1953 feet/day to 0.7581 feet/day. Based on this data, the
average hydraulic conductivity in the shallow aquifer zone was calculated to be 0.4767 feet/day.
The hydraulic conductivity in the deep aquifer zone was calculated to be 0.254 feet/day.
Seepage velocity was calculated using the approximate horizontal hydraulic gradient between
monitoring wells MW-4 and MW-2 of 0.018 feet/foot and the calculated average shallow hydraulic
conductivity of 0.4767 feet/day. The assumed effective porosity value of 40% for a sandy silt
material with partially weathered rock was obtained from the AQTESOLV website. The calculated
seepage velocity was 7.83 feet/year.
4.0 CORRECTIVE ACTION AND ASSESSMENT
4.1 Monitoring Well, Recovery Well, and Air Sparge Well Installation
On October 9 and 10, 2023, ATC supervised the installation of two recovery wells (RW-2 and
RW-3) one Type III monitoring well (TW2) and two air sparge wells (AS-1 and AS-2). The recovery
and air sparge wells were installed to enhance the effectiveness of MMPE events and MMPE/Air
Sparge events. Telescoping well TW-2 was installed to evaluate the extent of the groundwater
plume at depth. ATC contracted with Environmental Drilling and Probing Services (EDPS), a
North Carolina certified well contractor, to drill the borings and install the monitoring wells.
Air sparge wells AS-1 and AS-2 were installed to depths of 30 and 41 ft-bgs respectively. Each
well was completed with two 28 and 39-foot lengths of a 2-inch diameter schedule-40 polyvinyl
chloride (PVC) riser with 2-feet of 0.010-inch slotted screen and solid riser to near ground surface.
The borehole annulus was filled with #2 sand filter pack to 2 feet above the top of the well screen
(26 and 37 ft-bgs respectively). Bentonite was placed from 24 to 35 ft-bgs, and grout to surface.
The well was completed at the ground surface with a flush-mounted traffic-bearing manhole set
in a concrete pad.
Recovery wells RW-2 and RW-3 were installed to depths of 40 and 35 ft-bgs respectively. Each
well was completed with two 5 and 10-foot lengths of a 2-inch diameter schedule-40 polyvinyl
Corrective Action Performance Report

chloride (PVC) riser with 30-feet of 0.010-inch slotted screen and solid riser to near ground
surface. The borehole annulus was filled with #2 sand filter pack to 2 feet above the top of the
well screen (4 and 8 ft-bgs respectively). Bentonite was placed from 2 to 6 ft-bgs, and grout to
surface. The well was completed at the ground surface with a flush-mounted traffic-bearing
manhole set in a concrete pad.
The Telescopic well (TW-2) was installed to a depth of 60 ft-bgs respectively. The well was
completed with one 40-foot length of a 6-inch diameter schedule-40 polyvinyl chloride (PVC) riser,
and 60-foot length of a 20-inch diameter schedule-40 polyvinyl chloride (PVC) riser with 10-feet
of 0.010-inch slotted screen and solid riser to near ground surface. The borehole annulus was
filled with #2 sand filter pack to 48 feet above the top of the well screen (48 ft-bgs respectively).
Bentonite was placed from 46 ft-bgs, and grout to surface. The well was completed at the ground
surface with a flush-mounted traffic-bearing manhole set in a concrete pad.
The borings were drilled using air rotary drilling methodology. Well locations are depicted on
Figure 2.
Monitoring wells were installed by a North Carolina certified well contractor. They were installed
per the specifications required in North Carolina Administrative Code, Chapter 15A, Subchapter
2C, part .0108. (15A NCAC 2C .0108). The wells were completed with a 2-foot-by-2-foot concrete
pad, 8-inch diameter well vault, and capped with a lockable water-tight cap.
On October 12, 2023, following the completion of the wells, RW-2, RW-3, TW2, AS-1 and AS-2,
were measured for top-of-casing (TOC) elevation relative to the existing well network. Monitoring
well construction and TOC elevation details are summarized in Table 5 and Table 6. The well
construction records are included in Appendix A.
4.2 Mobile Multi-Phase Extraction Event
On October 30, 2023, Zava Industrial, Inc. (Zava) located in Graham, North Carolina, mobilized
to the site for performance of a 96-hour MMPE event, using monitoring wells MW-5, MW-8, MW-
10, and recovery wells RW-1 and RW-2 as target extraction wells. Air sparge well AS-1 was used
to introduce air into the formation. ATC was on site to record liquid level data from the extraction
wells and supervise system set up and initiation. Prior to starting the MMPE event, LNAPL was
measured in monitoring wells MW-5, MW-8, MW-10, and recovery wells RW-1 and RW-2 ranging
in thickness from 0.00 feet in MW-5 to 4.93 feet in MW-8. ATC personnel returned to the site on
November 3, 2023, to supervise the MMPE shut down activities and record liquid level
measurements from the extraction wells. After the MMPE event was completed, LNAPL was not
measured in the extraction wells A summary of current and historical groundwater elevation data
is included in Table 6.
The MMPE system actively recovered free-phase LNAPL, contaminated groundwater, and soil
vapors from monitoring wells MW-5, MW-8, MW-10, and recovery wells RW-1 and RW-2, for
approximately 96 hours. System monitoring was provided by Zava personnel. Over the course of
the 96-hour event, approximately 5,468 gallons of fluids were recovered from wells MW-5, MW-

8, MW-10, and recovery wells RW-1 and RW- including approximately 30 gallons of free-phase
LNAPL, as measured in the tanker. Note that actual LNAPL recovered during the MMPE event is
likely greater than 30 gallons, as the product and water had not fully separated when the initial
measurements were made. Based on the emissions calculations provided by Zava, 285.40
pounds (52.95 equivalent gallons) of petroleum hydrocarbons were recovered as vapor. A copy
of the MMPE report provided by Zava, including the disposal manifest, is included in Appendix
B.
On November 6, 2023, Zava Industrial, Inc. (Zava) located in Graham, North Carolina, mobilized
to the site for performance of a 96-hour MMPE event, using monitoring wells MW-1, MW-5, MW-
9, MW-10, and recovery wells RW-1 and RW-3 as target extraction wells. ATC was on site to
record liquid level data from the extraction wells and supervise system set up and initiation. Prior
to starting the MMPE event, LNAPL was measured in wells MW-1 (1.20 feet), MW-5, MW-7, MW-
9, MW-11, and RW-1 ranging in thickness from 0.03 feet in MW-11 to 1.20 feet in MW-1. ATC
personnel returned to the site on November 10, 2023, to supervise the MMPE shut down activities
and record liquid level measurements from the extraction wells. After the MMPE event was
completed, LNAPL was measured in well MW-1, MW-5, and MW-9 at thicknesses of 0.02 feet,
0.05 feet, and 0.38 feet, respectively, and was not measured in wells MW-10, RW-1, or RW-3. A
summary of current and historical groundwater elevation data is included in Table 6.
The MMPE system actively recovered free-phase LNAPL, contaminated groundwater, and soil
vapors from monitoring wells MW-1, MW-5, MW-9, MW-10, and recovery wells RW-1 and RW-3,
for approximately 96 hours. System monitoring was provided by Zava personnel. Over the course
of the 96-hour event, approximately 6,268 gallons of fluids were recovered from wells MW-5, MW-
8, MW-10, and recovery wells RW-1 and RW- including approximately 11 gallons of free-phase
LNAPL, as measured in the tanker. Note that actual LNAPL recovered during the MMPE event is
likely greater than 11 gallons, as the product and water had not fully separated when the initial
measurements were made. Based on the emissions calculations provided by Zava, 243.49
pounds (45.17 equivalent gallons) of petroleum hydrocarbons were recovered as vapor. A copy
of the MMPE report provided by Zava, including the disposal manifest, is included in Appendix
B.
A summary of LNAPL recovery efforts at the site to date is provided in Table 8. Subsequent liquid
level gauging indicates LNAPL remains present at the locations of MW-1, MW-5, and MW-9.
4.3 Liquid Level Measurements
On December 7, 2023, ATC conducted a groundwater sampling event to evaluate the
effectiveness of the MMPE event. Monitoring wells MW-1 through MW-14, TW-1, TW-2 and RW-
1 through RW-3 and AS-1 and AS-2 were gauged for liquid levels and total well depths prior to
sampling activities using an oil/water interface probe (IP) or water level indicator. LNAPL
thickness was measured in wells MW-1 (0.20 feet), MW-5 (0.03 feet), MW-7 (0.58 feet), MW-8
(0.40 feet), MW-9 (0.60 feet), MW-10 (0.49 feet), MW-11 (3.00 feet), MW-13 (0.01 feet), RW-1
(0.47 feet) RW-2 (0.02 feet) and RW-3 (0.69 feet). Monitoring well construction information is
included in Table 5. Current and historical liquid level information is summarized in Table 6.

The horizontal hydraulic gradient was calculated to be 0.121 feet/foot between monitoring wells
MW-12 and MW-11. The horizontal hydraulic gradient was calculated to be 0.036 feet/foot
between monitoring wells MW-14 and MW-13. The horizontal hydraulic gradient was calculated
to be 0.096 feet/foot between monitoring wells MW-12 and MW-13.
The vertical hydraulic gradient between Type II monitoring well MW-1 and Type III monitoring well
TW-1 was calculated to be approximately 0.01173 feet/foot in the upward direction. A
groundwater elevation map depicting groundwater flow to the north-northeast is included as
Figure 3. The distribution of LNAPL at the site, based on the December 7, 2023, measurements
is depicted on Figure 5.
4.3 Groundwater Sampling Results
On December 7, 2023, ATC conducted a monitoring well sampling event on wells MW-2, MW-3,
MW-4, MW-6, MW-12, MW-14, TW-1, TW-2, AS-1 and AS-2. Monitoring wells MW-1, MW-5, MW-
7, MW-8, MW-9, MW-10, MW-11, MW-13, RW-1, RW-2, and RW-3 were not sampled on
December 7, 2023, due to the presence of measurable LNAPL. The wells were purged prior to
sample collection using new, disposable PVC bailers or a decontaminated submersible pump and
new tubing, while wearing new, disposable nitrile gloves. Purging was accomplished by removing
approximately three well volumes or until the well was purged dry and allowed to recharge. Upon
sample collection, water quality parameters were measured and recorded in the field notes.
Groundwater samples were placed into laboratory provided containers, sealed and labeled,
placed into an ice-filled cooler and submitted under chain of custody protocol to Pace for analysis
by Standard Method 6200B for VOCs and oxygenates.
Groundwater analytical results were compared to GCLs and 2L Standards. Results from the
sampling events indicated the following:
LNAPL thickness was measured in wells MW-1 (0.20 feet), MW-5 (0.03 feet), MW-7 (0.58
feet), MW-8 (0.40 feet), MW-9 (0.60 feet), MW-10 (0.49 feet), MW-11 (3.00 feet), MW-13
(0.01 feet) RW-1 (0.47 feet), RW-2 (0.02 feet), and RW-3 (0.69 feet).
Dry-cleaning solvent tetrachlorethylene (PCE) was detected above the North Carolina 2L
Groundwater Quality Standards as defined in Title 15A, NCAC, Subchapter 2L, Part .0202
(2L Standard) in eight monitoring wells (AS-2, MW-2, MW-3, MW-6, MW-12, MW-14, TW-
1, and TW-2), and PCE was detected with levels above the North Carolina Gross
Contamination Standards in MW-3. Trichloroethylene (TCE) was detected above the 2L
Standards in seven wells (AS-2, MW-2, MW-3, MW-12, MW-14, TW-1, and TW-2).
Monitoring wells AS-1, AS-2, MW-2, MW-3, MW-6, MW-12, MW-14, TW-1, and TW-2
contained multiple petroleum constituents at concentrations over 2L Standards,
specifically benzene, ethylbenzene, xylenes, MTBE, naphthalene, isopropyl benzene, and
1,2,4-trimethylbenzene.
Oxygenates were detected in multiple monitoring wells but were not over the 2L
Standards.
Well MW-4 did not contain VOCs above the laboratory method detection level.

5.0 CONCLUSIONS AND RECOMMENDATIONS
From October to November 2023 ATC conducted assessment activities for the Circle K Store
2720828, located at 10329 Park Road, in Charlotte, Mecklenburg County, North Carolina.
Assessment activities included the installation of four Type II monitoring wells and one Type III
well, two 96-hour MMPE events, a groundwater sampling event, and water level gauging
activities.
Prior to the MMPE event, LNAPL was measured in wells MW-8 (4.93 feet), MW-10 (0.49 feet),
and RW-2 (0.02 feet) prior to starting the system. Approximately 5,468-gallons of fluids were
recovered from wells MW-1, MW-5, and RW-1. At least 30 gallons of free-phase LNAPL was
measured in the tanker at shut down, with approximately 52.95 gallons of VOCs removed as
vapor for the first MMPE event. After the second MMPE event, LNAPL was measured in wells
MW-1 MW-5, MW-7, MW-9, MW-11, and RW-1 ranging in thickness from 0.03 feet to 1.20 feet
prior to starting the system. At least 11 gallons of free-phase LNAPL was measured in the tanker
at shut down, with approximately 45.17 gallons of VOCs removed as vapor for the first MMPE
event. The MMPE events appear to be an effective method of LNAPL recovery.
During the subsequent groundwater monitoring event and gauging activities, LNAPL thickness
was measured in wells MW-1 (0.20 feet), MW-5 (0.03 feet), MW-7 (0.58 feet), MW-8 (0.40 feet),
MW-9 (0.60 feet), MW-10 (0.49 feet), MW-11 (3.00 feet), MW-13 (0.01 feet), RW-1 (0.47 feet)
RW-2 (0.02 feet) and RW-3 (0.69 feet). LNAPL thickness in wells MW-1 and MW-5 has decreased
significantly since detected in 2018. However, the presence of LNAPL in MW-13 indicates the
extent of LNAPL has not been fully delineated to the south-southeast of the source area.
Groundwater samples collected after the MMPE event indicated PCE was detected in well MW-
3 in excess of the GCL, and over the 2L Standard in wells AS-1, AS-2, MW-2, MW-6, MW-12,
MW-14, TW-1, and TW-2, along with TCE, in AS-2, MW-2, MW-3, MW-12, MW-14, TW-1, and
TW-2. TCE and PCE are chemicals typically detected in solvent releases. ATC does not have
any evidence of a solvent release on the Circle K Store 2720828 property. Therefore, any TCE
or PCE detected in the groundwater samples collected at the Circle K Store 2720828 are assumed
to not be related to the UST release.
Multiple other petroleum constituents were detected at concentrations exceeding 2L Standards in
monitoring wells AS-1, AS-2, MW-2, MW-3, MW-6, MW-12, MW-14, TW-1, and TW-2. Petroleum
constituents were not detected in well MW-4.
Dissolved-phase petroleum contamination in groundwater has not been horizontally delineated,
with the exception of the western portion of the site as indicated by the analytical results of MW-
4.

Based on the findings of the current and previous site activities, ATC recommends the following:
Conduct an MMPE/AS event, the first utilizing MW-1, MW-8, MW-9, MW-11, and
RW-3 as target extraction wells.
Complete a comprehensive groundwater monitoring event approximately 30 days
after the MMPE/AS events and report findings in a Corrective Action Performance
Report.

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.
