2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) submits this Corrective Action Performance Report
Report (CAPR) for The Corner Grocery located at 101 McAdenville Road, Lowell, Gaston County,
North Carolina. The associated operation and maintenance (O&M) and groundwater sampling
were performed based on the Task Authorization (TA-21), dated July 13, 2023, by North Carolina
Department of Environmental Quality (NCDEQ). The reporting period for this CAPR is for June
2023 through October 2, 2023.

The approved TA-21 included the sampling of seven monitoring wells (MW-1, 2, 3, 4, 6, 9, and
10), the monthly measurement of water levels, pressures dissolved oxygen levels, and depth to
water in four wells (MW-2, 6, 9, and 10), monthly PID readings and flows from the soil vapor
extraction (SVE) portion of the remediation system, operation and maintenance of the remediation
system, and monthly sampling of the SVE emissions.

ATC collected VE emission samples on August 3, 2023, September 6, 2023, and October 2, 2023
for laboratory analysis. ATC collected groundwater samples on September 20, 2023 from
monitoring wells MW-1, MW-2, MW-3, MW-4, MW-6, and MW-9. Monitoring well MW-10 could
not be located.

Cleanup Goals:
 Free Product: Not required. Free product has not been present at the site.
 Soil: Not required. Concentrations are less than Residential MSCCs.
 Groundwater: Reduce benzene concentrations to below the GCL.

The air sparging system was down between June 24, 2023 and August 3, 2023 due to an electrical
breaker issue associated with the sparging system. The air sparging system was also down
between September 7, 2023 and October 2, 2023, due to a spent oil/water separator/filter in the
air discharge line (replaced on October 10, 2023).

2.1 Free Product
Free product or light-non aqueous phase liquid (LNAPL) is not present and has not been present
at the site.

2.2 Contaminant Mass/Concentrations
The benzene concentrations (presented in µg/L) in wells MW-2 and MW-6 prior to and following
startup of corrective action are presented below. Between June 28, 2023 and September 20,
2023, benzene concentrations continued to decrease significantly in MW-2, and decreased
slightly in MW-6. Benzene concentrations in well MW-9 increased significantly, to be above the
GCL. The increase in benzene and other volatile organic compounds (VOCs) in MW-9 may be an
anomaly, or possibly indicative of the sparging system moving the plume. This will be further
evaluated during the next quarterly groundwater monitoring event.

Date 1/31/2023 6/28/2023 9/20/2023 Change (last 2 events)
MW-2 11,900 163 48.6 -70%
MW-6 8,130 6,470 6,010 -7%
MW-9 969 377 7,900 +1,995%

The vapor emission samples collected on August 3, 2023, September 6, 2023, and October 2,
2023, indicated benzene concentrations ranging from 32 to 83 micrograms per cubic meter

(µg/m3) and total petroleum hydrocarbons (TPH) ranging from 1,700 to 4,500 µg/m3. The
estimated mass of TPH removed was approximately 60 pounds.

2.3 Remedial Action Plan
The corrective action plan includes air sparging in three sparge wells and three vapor extraction
wells in the area of monitoring wells MW-2 and MW-6, to reduce benzene concentrations to below
the GCL.

2.4 Remedial Action Effectiveness
Based on the continued reduction in benzene concentrations in MW-2 and MW-6, the remedial
action appears to be effective. However, the decrease in MW-6 was less than indicated during
the previous quarter, and the benzene concentration well MW-9 increased significantly to be
above the GCL. The lesser reduction in benzene concentrations in MW-6 may be the results of
the down time of the air sparging system during the quarter. The increase in benzene
concentrations in well MW-9 may be an anomaly or the result of enhanced movement of the plume
by the air sparging. Both of these conditions will be further evaluated during the next quarter of
O&M and monitoring.

2.5 Receptors
No water supply wells area located within 1,000 feet of the source area and no surface water
bodies are located within 500 feet of the source area.

3.0 SITE HISTORY AND CHARACTERIZATION
3.1 UST Owner and Operator Information
Refer to Table 1.

3.2 UST Information
Refer to Table 2.

3.3 Non UST Information
No above ground storage tanks are located at the site.

3.4 Description of the Release
During the installation of the 12,000-gallon gasoline UST on September 19, 2006, adjacent to the
existing UST basin, soil was removed and stockpiled. The analysis of soil sampling indicated TPH
concentrations as high as 1,140 milligrams per kilogram (mg/kg). Subsequent soil and
groundwater sampling indicated a release of gasoline, with the highest concentrations located
along piping and near dispensers.

3.5 Site Characteristics
The use of the site and surrounding properties include commercial and residential uses. The
nearest residence is located approximately 270 feet southwest of monitoring well MW-3. Surface

cover at the site is mostly asphalt and concrete pavement with grassed areas east of the building
and pavement. The surface cover of the surrounding properties also include a mixture of paved
and grassed areas.

The site is located on a topographic ridge at an elevation of approximately 780 feet. Groundwater
flow is to the east, toward an intermittent stream located approximately 1,200 feet from the site.

3.6 Geology/Hydrogeology
The site lies in the Charlotte Belt of the Piedmont Physiographic Province. The bedrock beneath
the site consists of granite. Bedrock was not encountered at a depth of 50 ft-bgs. The regolith
consists of red-orange silty clay transitioning to sandy silt with depth.

Based on groundwater elevation data at the site, groundwater flow is to the east. The depth to
groundwater in the shallow wells has ranged from approximately 8 ft-bgs to approximately 22.5
ft-bgs since May 2007, with the highest groundwater levels occurring on June 4, 2020 and the
lowest groundwater levels in 2018.

3.7 Adjoining Properties
Properties adjoining the site include the following:

3.8 Potential Receptors
No water supply wells have been identified within 1,000 feet of the source area. No surface water
bodies have been identified within 500 feet of the source area.

3.9 Remedial Action Implementation
The remediation system was activated on March 22, 2023. This is the first groundwater monitoring
event following startup of the system.

3.10 Progress of Remedial Action
The September 20, 2023 groundwater sampling was the second groundwater monitoring event
following startup of the system. The results indicated continued reduction in benzene
concentrations in wells MW-2 (70%) and MW-6 (7%). The benzene concentration in MW-2 was
significantly less than the GCL. The benzene concentration in MW-6 was 6,010 µg/L. The
benzene concentration observed in downgradient well MW-9 (7,900 µg/L) was significantly
greater than the June 28, 2023 concentration (377 µg/L). The increase in concentration may be
an anomaly, or the result of the air sparing pushing the plume downgradient. The air sparging
system operated only 36% of the time for the quarter due to a couple of issues described below,
and that reduced run time may be the cause of the less than planned reduction of benzene in
MW-6.

4.0 GROUNDWATER MONITORING
On September 20, 2023, ATC measured the groundwater levels in monitoring wells MW-1 through
MW-4, MW-6, and MW-9. Monitoring well MW-10 could not be located during field activities and
is covered with approximately 6 to 8 inches of soil from the installation of the remediation system
and the soil is very dry and hard. Additional effort will be made to uncover the well prior to the
next sampling event. The location of the monitoring wells, and remediation wells (air sparge wells
AS-1 through AS-3 and vapor extraction wells VE-1 through VE-3) installed in January 2023 are
illustrated on Figure 2. The depth to groundwater and groundwater elevations are presented in
Table 3. A Groundwater Elevation Contour Map with the January 31, 2023 groundwater
elevations is presented as Figure 3. Groundwater flow is generally to the east to northeast.

On September 20, 2023, ATC also purged the monitoring wells and collected samples for
laboratory analysis. The samples were submitted to Pace Analytical for analysis of VOC using
Standard Method (SM) 6200B. Field notes of the groundwater sampling are included in Appendix
A, and a copy of the laboratory report is included in Appendix B.

Recent and historical groundwater sampling results are presented in Table 4 and Table 5,
respectively. Based on the groundwater sampling conducted to date, concentrations of one or
more VOCs have exceeded the 2L Standards in each of the 7 shallow monitoring wells. During
the September 2023 sampling event, benzene was detected above the GCL of 5,000 µg/L in wells
MW-6 and MW-9 at concentrations of 6,010 µg/L and 7,900 µg/L, respectively. Benzene was
detected in well MW-2 at a concentration of 48.6 µg/L, compared to the January 2023
concentration of 11,900 µg/L Benzene concentrations are illustrated on Figure 4. VOCs detected
above the 2L Standards are illustrated on Figure 5.
5.0 FREE PRODUCT REMEDIATION
Free product or light-non aqueous phase liquid (LNAPL) is not present and has not been present
at the site.
6.0 SOIL REMEDIATION
Soil remediation is not required, since contaminant concentrations are less than the Residential
MSCCs.

7.0 GROUNDWATER REMEDIATION
7.1 Remedial Action Plan
The August 13, 2021 Corrective Action Feasibility Study included the results of air sparging and
vapor extraction pilot testing, along with the planned remediation system as presented below.

 an air compressor capable of providing air to three 2-inch diameter sparge wells screened
from 45 to 50 ft-bgs with individual well flow rates and pressures of 5 scfm and 30 psi,
respectively, with an anticipated radius of influence of 30 feet;
 a vacuum blower capable of removing soil vapor from three 4-inch diameter vapor
extraction wells screened from 5 to 15 ft-bgs with individual well flow rates and pressures
of up to 40 cfm and up to 32 inches of water vacuum, respectively, with an anticipated
radius of influence of 30 feet; and
 three air sparge wells and three vapor extraction wells.

 The remediation equipment is contained within a trailer placed behind the rear of the store
building (northeast side).

Remedial Action Implementation

ATC supervised the installation of the remediation wells and system between January 16 and
February 14, 2023. The remediation system was inspected on February 23, 2023 and electrical
power was provided to the system on March 15, 2023. The system was started on March 22,
2023.

The remediation system includes air sparging using three sparge wells (AS-1, AS-2, and AS-3)
and three vapor extraction wells (VE-1, VE-2, and VE-3). The locations of the wells are indicated
on Figure 3. The operation of the remediation system began on March 22, 2023. The remediation
system is rented from LMS Manufacturing, LLC in Marianna, Florida. The system includes a
telemetry system that sends daily reports of the cumulative run times for the air sparging and
vapor extraction components and the air sparging pressure in pounds per square inch (psi) and
the vapor extraction vacuum pressure in inches of mercury (“Hg). Selected dates for the reporting
period (July - September 2023) are presented in Table 6. Readings of pressures and flows from
each well measured at the remediation system are presented in Table 7. Field notes of the O&M
system site visits are included in Appendix A.

On March 22, 2023, the initial operation of the system began. The SVE system was set to yield
2.5 “Hg for each of the three vapor extraction wells. The pressures to the sparge wells were slowly
increased in steps allowing for the water to be pushed out of the wells and sparging to begin. The
final pressures and flow just prior to leaving the site were 26 psi and <1 cubic feet per minute
(cfm) for AS-1, 16 psi and 2.4 cfm for AS-2, and 27 psi and 2.4 cfm for AS-3.

Vapor Intrusion Issues
On March 29, 2023, ATC decreased the pressure to sparge well AS-2 due to apparent petroleum
vapors entering the store building, based on observations by the occupants. ATC attempted to
decrease the sparging pressure to eliminate the vapors in the building, however, any sparging in
AS-2 resulted in vapors in the building. ATC suspects that vapors are entering a utility trench that
leads to the office area of the building where the vapors were most apparent. Sparging may be
resumed in the future as concentrations continue to decrease in the groundwater.

Sparging System
During the reporting period of July - September 2023, the AS system was off (June 24, 2023
through August 2, 2023) due to an issue with the breaker. The breaker issue was resolved on
August 2, 2023. During a site visit on September 7, 2023, oil was leaking from the oil/water
separator filter on the discharge line from the air compressor. The SVE system readings were not
recorded on September 7, 2023. The AS portion was turned off, and a new filter was ordered.
The filter was replaced on October 10, 2023 and the AS portions was reactivated. For the
reporting period, the sparging system operated 36%.

Vapor Extraction System and Mass Removal
During the reporting period of July 2023 through October 2, 2023, the SVE portion of remediation
system ran continuously. The vapor flow rates from the individual vapor extraction wells ranged
from 22 to 97 cfm, with total flows ranging from 87 to 183 cfm.

ATC collected VE emission samples on August 3, 2023, September 6, 2023, and October 2, 2023
for laboratory analysis by EPA Method TO-18. The samples were collected from the sample port
located between the moisture knockout tank and the vacuum blower, after shutting the SVE

system down. The samples were collected using a peristaltic pump connected to a Tedlar bag,
after purging the sample tubing.

The vapor samples were submitted to Analytical Environmental Services, Inc. in Atlanta, Georgia
(via Waypoint Analytical in Charlotte, North Carolina) for the analysis of benzene, ethylbenzene,
toluene, and total xylenes (BETX) and total petroleum hydrocarbons (TPH), using EPA Method
TO-15. Field notes of the sampling events are included in Appendix A. The results are
summarized in Table 8, and the laboratory reports are included in Appendix B.

Generally, the concentrations of BETX and TPH were greatest in the September 6, 2023 sample.
The concentrations of benzene ranged from 32 micrograms per cubic meter (µg/m3) on August 3,
2023 to 83 µg/m3 on September 6, 2023. Based on the TPH concentrations, vapor flow rates and
run times, the mass removal is estimated to be approximately 60 pounds (Table 8).

7.2 Remediation Chronology
See above for the second quarter of operational status of the remediation system. The projected
reduction in benzene concentrations presented in the October 31, 2022 Record of Decision was
15 to 25% per quarter. The results of the September 20, 2023 groundwater sampling indicated
that the progress milestones are being met by the active remediation for MW-2. The average
quarterly reduction in benzene for MW-6 is approximately 13%, with the reduced level of
remediation likely due to the down time associated with the sparging system issues. However,
the significant increase in benzene concentration in MW-9, if not an anomaly, may indicate that
the sparging system has pushed the plume downgradient. Another sampling event is
recommended to confirm that the increase in MW-9 is real. Thus, the progress milestones were
not met based on the results for monitoring wells MW-6 and MW-9.

7.3 Remediation Costs
Cost for the installation and startup of the system 56,261.50
Cost for the first quarter of corrective action (est) 16,000.00
Cost for the section quarter of corrective action (est) 16,000.00
Total 88,261.50
8.0 CONCLUSIONS
For the reporting period for this report (June 2023 through October 2, 2023), the vapor extraction
portion of the remediation system operated 100% percent of the time. The air sparging portion of
the remediation system operated 36% of the time with down time due to an electrical breaker
issue for the first down time and due to a spent oil/water separate filter on the air compressor
discharger or sparge line.

The operation of the remediation system appears to have been effective in reducing benzene
concentrations as evidenced by the reductions in MW-2 to 48.6 µg/L, with a lesser reduction of
7% in well MW-6 from 6,470 µg/L to 6,010 µg/L. The increase in the benzene concentration in
MW-9 from 377 µg/L to 7,900 µg/L is significant. The increase may be due to an anomaly or the
result of air sparging activities pushing the plume int the downgradient direction. ATC
recommends further evaluation of the cause of the increase with the results of the next quarterly
sampling event scheduled for December 2023. Based on the results for monitoring wells MW-6
and MW-9, the progress milestones were not met for the second quarter. The reduced air sparging
run time is likely the cause for the lesser than planned reduction rate in MW-6, with that to be
corrected during the third quarter. The increase benzene concentrations in MW-9 will be

Dear Al Quarles:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 9/6/2023 for the analyses presented in the
following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136
Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time.
Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information. Sincerely,
Danyale Love Project Manager

ANALYTE QUALIFIERS
This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be
considered an estimated value.IH
Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1
Analyte recovery in the matrix spike was outside QC limits for one or more of the constituent analytes used in the
calculated result.MS
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
