2.0 EXECUTIVE SUMMARY
ATC Associates of North Carolina, P.C. (ATC) submits this Monitoring Report documenting a
groundwater monitoring event in August and September 2023 at Herlocker Oil Company
(Herlocker) site. The report has been completed based on a May 10, 2023, Task Authorization
(TA-1) by the Trust Fund Branch of the Underground Storage Tank (UST) Section, Division of
Waste Management, North Carolina Department of Environmental Quality (NCDEQ). The work
was performed as part of the State Lead Contract # N70522-B between the NCDEQ and ATC.

The incident is associated with a releases of gasoline, diesel and kerosene from various USTs
removed in 1996 and 2003. No USTs have been installed at the site since the removal of the
former USTs. Thus, this report documents impact conditions likely related to the former UST
system.

As approved in TA-01, ATC sampled eight monitoring/recovery wells (MW-5, MW-6R, MW-12R,
MW-14, MW-15, MW-18, RW-2, and RW-4). Due to a field error, monitoring well MW-4R was
sampled on August 25, 2023 instead of recovery well RW-4. ATC returned to site September 19,
2023 and sampled recovery well RW-4. ATC also measured liquid levels in 16 additional
monitoring/ recovery wells. Monitoring well MW-9 could not be located and monitoring well MW-10
was not accessible. The groundwater samples for were analyzed for volatile organic compounds
(VOCs) including ethanol, 1,2-dibromoethane (ethylene dibromide or EDB) and oxygenates. The
site conditions based on the recent and historical assessment activities are presented below and in
the Conceptual Site Model (CSM) in Appendix A, based on the recent and historical assessment
activities:

 No water supply wells are reportedly located within 1,000 feet of the source area. Municipal
water is available to the site and surrounding area;
 No surface water bodies are located within 500 feet of the source area;
 The depth to groundwater in August 2023 ranged between 4.31 feet below top of casing (ft-
toc) in well MW-6R to 23.95 ft-toc in well MW-11, with groundwater flow generally to the
east;
 Light non-aqueous phase liquid (LNAPL) was detected in monitoring well MW-14 (0.01
feet);
 Benzene exceeded the Gross Contamination Level (GCL) in well MW-12R at a
concentration of 5,120 micrograms per liter (µg/L); and
 Multiple VOCs were detected at concentrations exceeding the 15A NCAC 02L .0202
groundwater quality standards (2L Standards) in each of the eight wells sampled.

VOC concentrations across the site have overall decreased over time, with a few exceptions.
Benzene concentrations in MW-12R has increased 50% since the January 2022 sampling event
and LNAPL was detected in MW-14 for the first time since December 2013, although at only 0.01
feet, near the detection limit of the oil/water interface probe. GCL exceedances or LNAPL were not
noted in well MW-14 since February 2004 (benzene exceeding the GCL) and December 2013
(LNAPL).

Based on the results of the August and September 2023 sampling event, ATC recommends the
following:

 Conduct remedial actions with considerations of chemical injection or Aggressive Fluid
Vapor Recovery (AFVR) to remove the limited LNAPL in MW-14 and reduce benzene
levels in MW-12R to less than the GCL;
 Conduct post-remedial action sampling of wells MW-12R and MW-14, and well MW-18 with
benzene exceeding the GCL in January 2022, to document the presence of LNAPL or GCL
exceedances; and,
 Consider closing the incident after at least two monitoring events indicate that LNAPL is not
present and that VOC concentrations are less than GCLs.

3.0 SITE DESCRIPTION
3.1 Site Characterization
ATC, under contract to the NCDEQ, provided environmental consulting services at the Herlocker
site, located at 612 West Main Street in Albemarle, Stanly County, North Carolina. Figure 1 depicts
the site on a topographic map. Based on historical information, no drinking water supply wells exist
within 1,000 feet of the source area and Little Long Creek is located approximately 520 feet east of
the source area. The risk classification for the incident is Intermediate due to the historical and
recent presence of LNAPL (0.01 feet in well MW-14 on August 25, 2023) and GCL exceedances
(5,120 µg/L benzene in well MW-12R on August 25, 2023). The area is serviced by municipal
water.

3.2 Site Background
The following was summarized by the NCDEQ from the Groundwater Monitoring Report
prepared by Geological Resources Inc., and received by the Mooresville Regional Office
(MRO), UST Section on February 23, 2017. Additional comments have been added by ATC.

The Herlocker Oil Company site is located at 612 West Main Street in Albemarle, Stanly
County, North Carolina. The site is located in an area where land use is a mix of commercial
and residential. No water supply wells are reported to be located within 1,500 feet of the source
area. The subject site and all surrounding properties use a municipal water source.

According to a June 29, 1999, Corrective Action Plan (CAP) prepared by Omega Environmental
Service, a release was discovered at the site on May 12, 1993. The source of the reported
release was suspected to be gasoline product lines. One 550-gallon waste oil UST, one 3,000-
gallon gasoline UST, one 6,000-gallon fuel oil UST and approximately 15 tons of petroleum
affected soil were removed from the site on May 1, 1996. Subsequently, three 6,000-gallon
gasoline USTs, one 6,000-gallon kerosene UST, one 6,000-gallon fuel oil UST and one 6,000-
gallon diesel UST were removed and closed on July 21, 2003.

A total of 20 shallow ground water monitoring wells (MW-1, MW-1A and MW-2 through MW-19),
two telescoping wells (DW-1 and DW-1) and four recovery wells (RW-1 through RW-4) have
been installed at the site during previous ground water assessment activities. A CAP
recommending the installation of four recovery wells and performing mobile multi-phase
extraction (MMPE) events on the wells was submitted by GRI on October 23, 2012 and
approved by NCDEQ on November 1, 2013.

The CAP was implemented in March 2013 with the installation of the recovery wells. MMPE
was subsequently conducted in April 2013 and the monitoring wells were sampled in May 2013
in accordance with the CAP schedule. Remediation goals at the site are the GCLs, and 10
times the surface water quality standards, due to a surface water body within 500 feet of the
source area.

On January 31, 2017, nineteen monitoring wells and four recovery wells were gauged, purged
and sampled. No LNAPL was measured in any of the monitoring wells or recovery wells.
Concentrations of benzene exceeding GCLs were reported in the ground water samples
collected from MW-12R, MW-18 and RW-2 during the January 2017 sampling event. The
February 6, 2017 Groundwater Monitoring Report was the last report submitted to NCDEQ prior
to this report.

In a Notice of Regulatory Requirements (NORR) issued on February 23, 2017, NCDEQ
recommended monitored natural attenuation (MNA) with semi-annual groundwater sampling
events. On December 7, 1992, staff from the NCDEQ Mooresville Regional Office identified
LNAPL in low lying areas near Little Long Creek as well as in Little Long Creek, located
approximately 600 feet east of the source area.

On February 5, 2018 the NCDEQ recommended annual sampling of monitoring wells MW-1,
MW-4R, MW-5, MW-6R, MW-10, MW-12R, MW-13, MW-14, MW-15, MW-16, MW-17, MW-18,
MW-19, and DW-1.

August 21, 2021 the site was accepted into the Trust Fund Branch State-Lead Program.

In January 2022, ATC sampled eight monitoring/recovery wells (MW-5, MW-6R, MW-12R, MW-
14, MW-15, MW-18, RW-2, and RW-4) and measured liquid levels in 14 additional
monitoring/recovery wells. Benzene exceeded the GCL in well MW-18 at a concentration of 6,070
micrograms per liter (µg/L). LNAPL was not detected in the monitoring or recovery wells. Multiple
VOCs including tert-amyl alcohol (TAA) and tert-butyl alcohol (TBA) were detected at
concentrations exceeding the 15A NCAC 02L .0202 groundwater quality standards (2L Standards)
in each of the eight wells sampled. ATC recommended the installation of a deeper monitoring
well for evaluation of the vertical extent of impact and to conduct and MMPE/AS event.

3.3 Site and Regional Geology

According to the Geologic Map of the Charlotte 1° x 2° Quadrangle, North Carolina and South
Carolina, produced by Goldsmith, et. al. in 1988, the site lies in the Carolina Slate Belt of the
Piedmont Physiographic Province of North Carolina. The rock type in this area has been
identified as thin and thick bedded metasandstone, metaconglomerate and metavolcanic rock
as part of the Floyd Church Formation. The shallow subsurface in most areas of the Piedmont
contains residual soil overburden, including structure-free residuum, saprolite, and 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. Depth to rock ranges from
ground surface at occasional outcrops to depths of greater than 100 feet in areas of easily
weathered rock.

Boring logs from historical assessment activities conducted at the site indicate that the site
subsurface generally consists of red, brown, and black clayey, sandy silt to depths between 20

feet below ground surface (ft-bgs) and 30 ft-bgs. Bedrock was encountered at the site at a depth
of 27 ft-bgs to 30 ft-bgs.

3.4 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. Based on gauging of the
monitoring well network, groundwater flow across the site is generally toward the northwest.
Depth to groundwater in the overburden aquifer at the site has historically ranged from
approximately 2.5 to 22 ft-bgs. Groundwater flow at the site is generally to the east toward Little
Long Creek located approximately 520 feet east of the source area.

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 are typically installed with a surface casing through the
unconsolidated material, and an open borehole into the bedrock where water-bearing fractures
are encountered.

4.0 GROUNDWATER CHARACTERIZATION
4.1 Groundwater Levels
On August 25, 2023, ATC measured the depth to water in MW-1, MW-1A, MW-3, MW-4R, MW-
5, MW-6R, MW-8, MW-11, MW-12R, MW-13, MW-14, MW-15, MW-16, MW-17, MW-18, MW-
19, DW-1, DW-2, RW-1, RW-2, RW-3, and RW-4. Monitoring well MW-9 was not located and
monitoring well MW-10 could not be accessed. Figure 2 depicts a site map with well locations.
LNAPL (0.01 feet) was detected in monitoring well MW-14 during the groundwater monitoring
event. Depth to groundwater during this event ranged between 4.31 ft-toc in well MW-6R to 23.95
ft-toc in well MW-11. Depth to groundwater and elevation data are summarized in Table 1. A
groundwater elevation contour map is presented as Figure 3. Based on groundwater elevation
data, groundwater flow is generally to the east, with horizontal gradient of approximately 0.09
feet/foot (ft/ft). Field notes and photographs from the groundwater monitoring events are
presented in Appendix B.

4.2 Groundwater Quality
On August 25, 2023, ATC collected groundwater samples from wells MW-5, MW-6R, MW-12R,
MW-15, MW-18, RW-2 and MW-4R. Due to a field error, monitoring well MW-4R was sampled on
August 25, 2023 in place of recovery well RW-4. ATC returned to site September 19, 2023 and
collected a sample from recovery well RW-4. ATC purged the wells of three well volumes prior to

groundwater sample collection to ensure collection of a representative sample was collected. Upon
completion of purging activities, water quality field parameters were measured for each sample.
Field parameters are included in Table 2.

The water samples were collected in laboratory-supplied, preserved containers, entered into chain-
of-custody control, placed on ice, and delivered to Pace Analytical in Huntersville, NC. The
groundwater samples were analyzed by EPA Method 6200B for VOCs including petroleum
compounds. The analytical reports are included as Appendix C.

Groundwater analytical results from the August 25, 2023 and September 19, 2023 monitoring
event are summarized in Table 3. Historical groundwater analytical results are shown in Table 4.
Groundwater analytical results indicated the following:

 Benzene exceeded the GCL in well MW-12R at a concentration of 5,120 micrograms per
liter (µg/L), compared to the January 2022 concentration of 3,400 µg/L; and
 Multiple VOCs were detected at concentrations exceeding the 15A NCAC 02L .0202
groundwater quality standards (2L Standards) in each of the eight wells sampled.

VOC concentrations across the site have overall decreased over time, with a few exceptions.
Benzene concentrations in MW-12R has increased 50% since the January 2022 sampling event
and LNAPL was detected in MW-14 for the first time since December 2013. The VOC
concentrations exceeding the 2L Standards and GCLs are shown in Figure 4. Estimated benzene
isoconcentrations are presented in in Figure 5.

As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of
the laboratory report was conducted. During the review, it was found that the samples were
received from the laboratory in acceptable condition and properly preserved. The samples were
analyzed within correct holding times and reported within the lab report, and the chain of
custody was properly completed by all parties. ATC collected one field blank during the August
2023 groundwater monitoring event. VOCs were not detected in the fidl blank. The laboratory
QC report shows that internal blanks were analyzed for each method that was used for the
original samples. Refer to the laboratory reports in Appendix B for details regarding QA results
for the laboratory samples and any noted exceptions. Overall, ATC concludes that the
laboratory results are usable and any exceptions do not significantly impact the conclusions
presented in this report.

5.0 CONCLUSIONS AND RECOMMENDATIONS
On behalf of the Trust Fund Branch of the UST Section, ATC has completed groundwater
sampling activities in Augusst and September 2023 for the Herlocker Oil Co. site, located at 612
West Main Street, Albermarle, Stanly County, North Carolina. The site conditions based on the
recent and historical assessment activities are presented below and in the Conceptual Site Model
(CSM) in Appendix A, based on the recent and historical assessment activities:

 No water supply wells are reportedly located within 1,000 feet of the source area. Municipal
water is available to the site and surrounding area;
 No surface water bodies are located within 500 feet of the source area;
 The depth to groundwater in August 2023 ranged between 4.31 ft-toc in well MW-6R to
23.95 ft-toc in well MW-11, with groundwater flow generally to the east;
 LNAPL was detected in monitoring well MW-14 (0.01 feet);

 Benzene exceeded the GCL in well MW-12R at a concentration of 5,120 µg/L; and
 Multiple VOCs were detected at concentrations exceeding the 2L Standards in each of the
eight wells sampled.

VOC concentrations across the site have overall decreased over time, with a few exceptions.
Benzene concentrations in MW-12R has increased 50% since the January 2022 sampling event
and LNAPL was detected in MW-14 for the first time since December 2013, although at only 0.01
feet, near the detection limit of the oil/water interface probe. GCL exceedances or LNAPL were not
noted in well MW-14 since February 2004 (benzene exceeding the GCL) and December 2013
(LNAPL).

Based on the results of the August and September 2023 sampling event, ATC recommends the
following:

 Conduct remedial actions with considerations of chemical injection or AFVR to remove the
limited LNAPL in MW-14 and reduce benzene levels in MW-12R to less than the GCL;
 Conduct post-remedial action sampling of wells MW-12R and MW-14, and well MW-18 with
benzene exceeding the GCL in January 2022, to document the presence of LNAPL or GCL
exceedances; and,
 Consider closing the incident after at least two monitoring events indicate that LNAPL is not
present and that VOC concentrations are less than GCLs.

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 EPAMethod 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
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
