2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) submits this Corrective Action Performance Report
for The Corner Grocery located at 101 McAdenville Road, Lowell, Gaston County, North Carolina.
The associated groundwater sampling and reporting was performed based on the Task
Authorization (TA-20), dated April 6, 2023, by North Carolina Department of Environmental
Quality (NCDEQ).

The approved TA-20 includes 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 April 19, 2023, May 23, 2023, and June 28, 2023 for
laboratory analysis. ATC collected groundwater samples on June 28, 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.

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. Note the reduction in the benzene
concentrations.

Date 1/31/2023 6/28/2023 Reduction
MW-2 11,900 163 99%
MW-6 8,130 6,470 20%

The vapor emission samples collected on April 19, 2023, May 23, 2023, and June 28, 2023,
indicated low concentrations of volatile organic compounds, with benzene ranging from 25 to 36
micrograms per cubic meter (µg/m3) and total petroleum hydrocarbons (TPH) ranging from 1,000
to 1,300 µg/m3. TPH concentrations decreased with time. The estimated mass of TPH removed
was 7 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.

Corrective Action Performance Report August 4, 2023
The Corner Grocery – NCDEQ Incident #36165 ATC Project #199AGG2301

2.4 Remedial Action Effectiveness
Based on the reduction in benzene concentrations of 99% in MW-2 and 20% in MW-6, the
remedial action appears to be effective. The June 28, 2023 benzene concentration in MW-2 was
well below the GCL. A 23% reduction in benzene concentration in MW-6 would reach the GCL
cleanup goal.

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.

3.8 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 June 28, 2023 groundwater sampling was the first groundwater monitoring event following
startup of the system. The results indicated significant reduction in benzene concentrations in
wells MW-2 (99%) and MW-6 (20%). The benzene concentration in MW-2 was significantly less
than the GCL. The benzene concentration in MW-6 was 6,470 µg/L.

4.0 GROUNDWATER MONITORING
On June 28, 2023, ATC measured the groundwater levels in monitoring wells MW-1, MW-2, MW-
3, MW-4, MW-6, and MW-9. Monitoring well MW-10 could not be located during field activities
and is presumed to be covered with soil from the installation of the remediation system. 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. The depth to
groundwater ranged from 13.18 ft-toc (MW-1) to 18.73 ft-toc (MW-9). Groundwater levels were
approximately 3 to 4 feet higher than in January 2023. A Groundwater Elevation Contour Map
with the June 28, 2023 groundwater elevations is presented as Figure 3. Groundwater flow is
generally to the northeast.

On June 28, 2023, ATC also collected samples from monitoring wells MW-1, MW-2, MW-3, MW-
4, MW-6, and MW-9 for laboratory analysis. Field parameters (temperature, conductivity, pH,
oxygen-reduction potential, and dissolved oxygen) were measured after purging and prior to the
collection of groundwater samples (Table 4). Dissolved oxygen level ranged from 0.9 milligrams
per liter (mg/L) in well MW-4 to 2.9 mg/L in MW-9. Note that the sparging system was off for
several days prior to groundwater sampling.

The samples were submitted to Pace Analytical for analysis of VOC using Standard Method (SM)
6200B including oxygenates. Field notes of the groundwater sampling are included in Appendix
A, and a copy of the laboratory report is included in Appendix B.

Recent groundwater sampling results are presented in Table 5. Historical groundwater sampling
results are presented in Table 6. Based on the groundwater sampling conducted to date,
concentrations of one or more VOCs have exceeded the 2L Standards in each of the ten shallow
monitoring wells and one deep monitoring well. Benzene was detected in one well (MW-6) at a
concentration exceeding the GCL. For the wells sampled, benzene concentrations in January
2023 and June 28, 2023 are presented below along with the percent change in benzene and a
general description of changes in other VOCs.

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;
Corrective Action Performance Report August 4, 2023
The Corner Grocery – NCDEQ Incident #36165 ATC Project #199AGG2301

6
 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
Installation and Startup
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 (March – June 2023) are presented in Table 7. Readings of pressures and flows from each
well measured at the remediation system are presented in Table 8. 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.

The remediation system ran continuously from the startup date of March 22, 2023 to June 23,
2023, when the system was turned off to allow for stabilization prior to groundwater sampling
conducted in June 28, 2023.

The vapor flow rates for the vapor extraction wells ranged from 29 to 92 cfm, with average total
flows of 102 to 207 cfm.

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 Failure
Following groundwater sampling, the remediation system was turned back on. Note that June
22, 2023 a drop in the sparging pressure was noted from 20.2 psi to 19.7, and on June 23, 2023,
the pressure was noted to be 3.2 psi. Due to the drop in sparging pressure and the planned
groundwater sampling, ATC shut down the system on June 23, 2023. Following the system restart
Corrective Action Performance Report August 4, 2023
The Corner Grocery – NCDEQ Incident #36165 ATC Project #199AGG2301

7
on July 28, 2023, the air compressor was building up pressures as designed, however, the
sparging pressure to the wells was still 0 psi. The cause of no sparging could not be determined
at that time. On August 3, 2023, ATC visited the site while discussing the issues with LMS
Manufacturing. The outlets of the air compressor were tripped. Two of the regulators were open
100% bleeding off air. LMS Manufacturing staff adjusted several settings within the control panel
via the telemetry system to enable restarting the system. The two issues were resolved, and the
system was restarted.

Vapor Emissions and Mass Removal
ATC collected vapor emission samples from the SVE system on April 19, 2023, May 23, 2023,
and June 28, 2023. 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 April
2023 sample was collected using a syringe transferring the vapor to the sample Tedlar bag. The
May and June samples were collected using a peristaltic pump, 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, total xylenes, 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
9, and the laboratory reports are included in Appendix C.

The concentrations of benzene, ethylbenzene, toluene, and total xylenes ranged from 11
micrograms per cubic meter (µg/m3) for toluene for the April and June 2023 samples to 68 µg/m3
for xylenes for the May 2023 sample. Excluding toluene, the May concentrations were slightly
higher than the April concentrations, and the June concentrations were less than the May 2023
concentrations. The TPH concentrations decreased from 1,300 µg/m3 in April to 1,200 µg/m3 in
May, to 1,000 µg/m3 in June. Based on the TPH concentrations, vapor flow rates and run times,
the mass removal is estimated to be 9 pounds between March 22, 2023 and June 28, 2023 as
presented in Table 8.

7.2 Remediation Chronology
See above for the first 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 June 28, 2023 groundwater sampling indicated that the
progress milestones are being met by the active remediation.

7.3 Remediation Costs
Cost for the installation and startup of the system 56,261.50
Cost for the first Corrective Action Performance Monitoring Report (est) 17,001.00
Total 73,262.50
8.0 CONCLUSIONS
Since startup on March 22, 2023 through June 28, 2023, the vapor extraction portion of the
remediation system operated 97% percent of the time with down time for the system off prior to
groundwater sampling. The air sparging portion of the remediation system operated 90% of the
time including the down time prior to groundwater sampling and a short time prior to the shutdown.
The sparging system would not resume due to issues with the sparging system and controls. The
system was restarted on August 3, 2023.

Lab Report Number: 23-179-0025 Client Project Description: The Corner Grocery
Dear Al Quarles:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 6/28/2023 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

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.
