2.0 EXECUTIVE SUMMARY

ATC Associates of North Carolina, P.C. (ATC) has completed a Groundwater Monitoring Report for the
Stalling’s Store site. This report documents a groundwater sampling event in January 2023 at the Stalling’s
Store site located at 4708 Old U.S. Highway 64 East in Pilot, Franklin County, North Carolina. The activities
were performed based on the December 15, 2022, Task Authorization (TA-04) 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 is being performed as part of State Lead Contract
#N122019A between NCDEQ and ATC.

Former petroleum USTs at the site released light non-aqueous phase liquid (LNAPL) to the subsurface prior to
their removal in 1993. This report documents impact conditions related to the former UST system. The site
consists of a single-story building currently occupied by Stalling’s Store. Nineteen water supply wells (SW-1
through SW-19) are located within 1,000 feet of the site. Municipal water is not available to the site or vicinity.
Sixteen monitoring wells (MW-2, MW-4, MW-5, MW-6, and MW-8 through MW-19), two intermediate depth
wells (DW-1 and DW-2), two deep monitoring wells (MW-20D and MW-21D), five recovery wells (RW-1 through
RW-5), seventeen air sparge wells (AS-1 through AS-17), and eighteen soil vapor extraction (SVE) wells (SVE-
1 and VE-2 through VE-18) are associated with the site. A soil vapor extraction and air sparge (SVE/AS)
treatment system operated at the site from April 2011 until February 2016. The treatment system was shut
down in 2016 and was removed from the site in 2019.

On January 19, 2023, ATC collected groundwater samples from shallow monitoring wells MW-2, MW-9, MW-
10, MW-11, MW-12, MW-13, MW-14, MW-16, MW-17, MW-18, and MW-19. ATC also collected samples
from recovery well RW-5 and deep monitoring wells MW-20D, MW-21D, DW-1, and DW-2. LNAPL was
detected in RW-1, RW-2, and RW-3 at thicknesses of 0.07 feet, 0.27 feet, and 0.09 feet, respectively.

Results from the monitoring event indicated numerous petroleum constituents were detected at
concentrations exceeding the respective 2L Standards in MW-9, MW-10, MW-18, MW-19, MW-20D, and
MW-21D, DW-1, DW-2, and RW-5. Benzene was detected at concentrations exceeding the respective
GCLs in MW-18, MW-19, MW-20D, and MW-21D. MTBE was detected at a concentration exceeding the
established GCLs in MW-18, MW-20D, and MW-21D. The laboratory analytical results from MW-21D
indicate that the vertical extent of the petroleum impacted groundwater plume is not fully delineated.

MTBE, 1,1-dichloroethene and 1,1-dichloroethane were detected in water supply well SW-5 at
concentrations above the laboratory detection limits, but below the 2L Standard. These constituents have
been historically detected in water supply well SW-5.

Based on the results of the groundwater assessment, ATC recommends the following:

 The installation of additional Type III vertical extent wells down-gradient from monitoring well MW-21D
to characterize the groundwater impacts in the deeper aquifer; and
 Performing a feasibility study upon the completion of vertical extent delineation to identify potential
remedial options for this site.

3.0 SITE DESCRIPTION

3.1 SITE CHARACTERIZATION

The former Stalling’s Store is located at 4708 Old U.S. Highway 64 East in Pilot, Franklin County, North
Carolina. Currently onsite is a single-story building that operates as a convenience store. The former UST
system at the site included one 3,000-gallon gasoline UST and one 7,000-gallon gasoline UST. The gasoline
USTs were removed from the site in 1993.

The site is bounded by Old U.S. Highway 64 East to the north, State Road 1746 to the east, a vacant lot to the
south, and a vacant residence to the west. Surrounding properties are characterized by residential, agricultural,
commercial, and institutional use. Nineteen water supply wells (SW-1 through SW-19) are located within 1,000
feet of the site. Water supply well ownership information is included in Table 1. A site topographic map is
included as Figure 1 and a site map depicting monitoring well locations and other pertinent site features is
included as Figure 2. A Potable Well Survey Map showing the locations of water supply wells SW-1 through
SW-19 is included as Figure 3.

3.2 SITE BACKGROUND

The site is located at the southwest corner of the intersection of Stallings Road (State Road 1746) and Old US
Highway 64 East (State Road 1770). A release of petroleum product was discovered during UST closure
activities in September 19931, at which time two USTs (one 3,000-gallon and one 7,000-gallon gasoline) were
permanently closed by removal. Soil samples analyzed by Environmental Protection Agency (EPA) Method
5030/8021 obtained during closure of the UST systems revealed the presence of total petroleum hydrocarbons
(TPH), identified as gasoline, at concentrations as high as 5,660 parts per million (ppm).

A water sample was obtained from a drinking water supply well adjacent to the site on October 18, 1993, by a
representative of the North Carolina Department of Environment, Health and Natural Resources (NCDEHNR),
now the NCDEQ. Analysis of this sample showed benzene to be present in the sample at a concentration of
160 part per billion (ppb). Other compounds were also found to be present in the sample. As a result of this
finding, the NCDEHNR issued a Notice of Regulatory Requirements (NORR) letter dated January 5, 1994,
outlining Ms. Horton’s legal obligations relating to the release as the tank owner/operator. It was later
determined that this well had been impacted by a release from the Lewis Farm Supply Site2.

The NCDEHNR issued an additional NORR letter on February 9, 1994, relating to the release confirmation
resulting from the closure of the USTs during September 1993. This letter directed that Ms. Horton take actions
to assess the contamination at the site, including a release investigation, initial abatement measures, LNAPL
removal (if necessary) and the performance of a Comprehensive Site Assessment (CSA) and Corrective Action
Plan (CAP).

Subsequent to receipt of these notices, Ms. Horton contracted Triangle Environmental, Inc., TRC
Environmental Corporation (TRC), Solutions-IES (Solutions), and ATC to perform activities necessary to
comply with the above referenced NORR letters. Numerous soil borings and groundwater monitoring wells
have been installed on the site and adjacent properties, during which time the store continued to function as a
gasoline station. The remaining UST was permanently closed by removal during December 20033. The site
continues to operate as a convenience store with no retail petroleum sales.

During previous site activities, TRC had collected quarterly groundwater samples from ten monitoring wells
located in the Stallings Store area. Two additional monitoring wells (MW-12 and MW-13) were installed on an
off-site property in November 2002 by TRC. Four monitoring wells (MW-14, MW-15, MW-16 and MW-17) were
installed on March 30 and 31, 2005.

Aggressive Fluid Vapor Recovery (AFVR) events had been conducted at the site by TRC as an interim measure
of remediation. At the direction of Ms. Dana Wolff of the NCDEQ, light non-aqueous phase liquid (LNAPL)
recovery by AFVR was suspended and the installation of a remediation system requested. AFVR events have
not been conducted at the site since October 2000. A total of seventeen shallow groundwater monitoring wells
(MW-1 through MW-17) and two Type III intermediate depth groundwater monitoring wells (DW-1 and DW-2)
have been installed at the site and surrounding properties. Two of the shallow groundwater monitoring wells,
MW-1 and MW-3, were converted to recovery wells by TRC and renamed RW-1 and RW-2, respectively. A 6-
inch diameter recovery well (RW-3) and two 4-inch diameter recovery wells (RW-4 and RW-5) were installed
by TRC in anticipation of the CAP implementation. However, the remediation system proposed by TRC was
never installed due to access problems associated with the effluent discharge at the Pilot Baptist Church. TRC
also completed an updated receptor survey for the site in July 2002.

Previous site activities were also conducted by ATC in late 2003 and in 2004. ATC’s activities included a
Mobile Multi-Phase Extraction (MMPE) event, the removal of one 10,000-gallon UST, and a groundwater
sampling event.

Solutions began work at the Stallings Store site in September 2004. Solutions oversaw the performance of
two MMPE events, completed two groundwater sampling events, and supervised the installation of four
additional groundwater monitoring wells (MW-14 through MW-17). The installation of the four monitoring
wells further defined the LNAPL plume at the site, and the sampling events indicated that on-site monitoring
wells have not been impacted by the release, except for well MW-10 that may be impacted by an off-site
source. It was determined that water supply well SW-2 was impacted by MTBE.

In October 2007, ATC submitted a pre-approval to perform pilot study activities at the site. However, after a
site visit in January 2008, LNAPL was detected in one of the monitoring wells and in several recovery wells
(MW-9, RW-1, RW-2, RW-4, and RW-5). The presence of LNAPL precluded the pilot study activities. ATC
submitted a change order in February 2008 to perform an MMPE event and a semiannual sampling event,
which took place in April 2008.

A new water supply well (SW-5) was installed at the Bunn property in January 2009. The well was installed
to a depth of 450 feet below ground surface (bgs). On July 1, 2009, an air sparge well and a soil vapor
extraction well were installed for pilot testing purposes. The pilot testing was conducted on July 8 and 9,
2009. On October 19, 2009, ATC submitted a Groundwater Monitoring and Pilot Test Results Report to the
NCDEQ summarizing the pilot study activities and the groundwater sampling event on July 8, 2009.

ATC conducted two groundwater sampling events and two MMPE events in 2010. The results are documented
in Groundwater Monitoring Reports and MMPE Event Results submitted on April 22, 2010, and August 25,
2010.

On May 28, 2010, ATC submitted a preapproval requesting the completion of tasks relating to the CAP.
NCDEQ approved the request in a letter of correspondence dated June 30, 2010. In September 2010, as per
the CAP, ATC supervised the installation of air sparge wells AS-2 through AS-13, AS-15, and AS-17 and soil
vapor extraction wells VE-2 through VE-18. Between October 2010 and January 2011, ATC supervised the
installation of the soil vapor extraction system and air sparge system. The treatment system was delivered in
December 2010 and started up in April 2011.

Due to complaints of petroleum odors by the site occupants, the air sparge system operated through 2012
when it was shutdown. The SVE system was shut down in February 2016 due to SVE motor malfunctions.
During this time, the responsible party requested acceptance into the North Carolina State Lead Program due
to financial hardships. The site was accepted into the North Carolina State Lead Program in December 2016.

In June 2017, ATC performed an updated water supply well survey in the surrounding vicinity of the site by
conducting a visual reconnaissance. Based on the water supply well survey, nineteen water supply wells (SW-
1 through SW-19) are located within 1,000 feet of the site. Several water supply wells (SW-1, SW-6 and SW-
11) provided water to several adjacent properties that did not have their own water supply wells. SW-1 also
provides water to the site property. Water supply well information is included as Table 1 and potential receptors
are presented in Figure 3. ATC also contacted the Franklin County Public Utilities Department and the City of
Zebulon Public Works Department to determine the availability of municipal water near the site. Public water is
not available to the site or surrounding area.

ATC submitted a Groundwater Monitoring Report on September 13, 2017, documenting the results of the SVE
motor inspection, the installation and sampling of two soil gas monitoring points, and monitoring well and water
supply well sampling activities performed in June and July 2017.

ATC submitted a Groundwater Monitoring Report on July 24, 2018, documenting the results of the monitoring
well and water supply well sampling activities performed in March 2018 and research regarding the use of laser
induced fluorescence (LIF) to further define the source area at the site.

ATC prepared a Light Non-Aqueous Phase Liquid Investigation report dated May 17, 2019, documenting the
results of an Ultraviolet Optical Screening Tool/Laser Induced Fluorescence (UVOST/LIF) investigation and
soil sampling event conducted in February and March 2019. The UVOST/LIF drilling technology is a direct
push system that produces vertical profiles of LNAPL in the subsurface. Based on the results of the
UVOST/LIF investigation and confirmatory soil analytical results, possible LNAPL or impacted groundwater
may be present at depths that had not been previously assessed. Specifically, the areas near LIF-2, LIF-4
and LIF-16 indicated possible LNAPL or impacted groundwater at depths greater than 25 feet.

ATC submitted a Supplemental Groundwater Investigation report on October 10, 2019 documenting the results
of an UVOST/LIF investigation and soil sampling event conducted in August 2019. Seven UVOST/LIF soil
borings (LIF-17 through LIF-23) were advanced in order to characterize and supplement the LNAPL
investigation at the site. Based on the results of the UVOST/LIF investigation, LIF-17 and LIF-19 indicated
possible LNAPL or elevated petroleum compound impacts in groundwater. Soil borings LIF-18, LIF-20, LIF-
21, LIF-22 and LIF-23 did not have %RE results above background. Results of the laboratory analysis
indicated exceedances to the Soil-to-Groundwater Maximum Soil Contamination Concentrations (MSCCs)
in borings SB-LIF-17 and SB-LIF-19 for benzene and numerous other petroleum compounds. The analytical
results for the most down gradient soil sample SB-LIF-23 did not exceed the laboratory detection limits.
Based on the results of the March 2019 and the supplemental UVOST/LIF investigations and confirmatory
soil analytical results, possible LNAPL or impacted groundwater may be present at depths that had not
been previously assessed in and adjacent to the former source area. The most down gradient soil boring
near water supply well SW-5 did not have any %RE readings above background and the confirmatory soil
analytical results were all below the laboratory detection limits. ATC recommended continued groundwater
monitoring and the installation of two deep monitoring wells to confirm the vertical extent of the impacted soil
and groundwater in and adjacent to the source area.

In November and December 2019, ATC supervised the removal of the remediation building and
components including the existing bollards, compound fence, overgrown vegetation, remediation system
manifold (15 air sparge lines and 18 SVE lines) and electrical connections to the remediation system.

On April 14, 2020, ATC submitted a Groundwater Monitoring Report documenting the collection of
groundwater samples from RW-1, RW-5, MW-4, MW-10, MW-11, MW-14, MW-15, MW-16, MW-17, MW-18,
and MW-19; sampled water supply well SW-5, and collected a field blank conducted in February 2020. LNAPL
was detected in RW-2 and RW-4 at a thickness of 0.78 feet and 0.58 feet, respectively. The laboratory
analytical results indicate petroleum hydrocarbon compounds at concentrations exceeding 2L Standards in
RW-1, RW-5, MW-10, MW-18, and MW-19. Benzene was detected in MW-18 and MW-19 above GCLs.
Water supply well SW-5 indicated toluene and 1,1-dichloroethene at concentrations above the laboratory
reporting limits, but below the 2L Standards. 1,1-dichloroethene concentrations have historically been
detected in SW-5.

On July 19, 2021, ATC submitted a Groundwater Monitoring Report documenting the collection of
groundwater samples from recovery wells RW-1 and RW-5, monitoring wells MW-10, MW-17, MW-18, and
MW-19, and water supply well SW-5 in June 2021. LNAPL was detected in RW-2 and RW-4 at thicknesses of
2.00 feet and 2.48 feet, respectively. The laboratory analytical results indicate petroleum hydrocarbon
compounds at concentrations exceeding 2L Standards in RW-1, RW-5, MW-10, MW-18, and MW-19. Benzene
was detected in MW-19 above GCLs. The laboratory analytical results from water supply well SW-5 indicated
the presence of 1,1-dichloroethene at concentrations above the laboratory reporting limits, but below the
2L Standards. 1,1-dichloroethene has historically been detected in SW-5.

On December 10, 2021, ATC submitted a Groundwater Monitoring Report documenting the installation of
one Type III monitoring well and subsequent groundwater sampling event. Groundwater samples were
collected from monitoring wells RW-1, RW-5, MW-10, MW-17, MW-18, MW-19, MW-20D, and water supply
well SW-5. Results from the monitoring event indicated numerous petroleum constituents were detected at
concentrations exceeding the respective 2L Standards in RW-1, RW-5, MW-10, MW-18, MW-19, and MW-
20D. Benzene was detected at concentrations exceeding the respective GCL in RW-1, MW-18, MW-19,
and MW-20D. MTBE was detected at a concentration exceeding the established GCL in MW-20D. 1,2-
Dichloropropane was detected at concentrations exceeding the established GCL in RW-1, RW-5, MW-18,
MW-19, and MW-20D. Toluene, MTBE, 1,1-dichloroethene, and 1,1-dichloroethane were detected in water
supply well SW-5 at concentrations above the laboratory detection limits, but below the 2L Standard. These
constituents have been historically detected in water supply well SW-5 at concentrations above the
laboratory detection limits but below the 2L Standard. ATC recommended the installation of a down-gradient
Type III vertical extent well and continued groundwater sampling.

On October 3, 2022, ATC submitted a Groundwater Monitoring Report documenting the installation of one
Type III monitoring well and subsequent groundwater sampling event. Groundwater monitoring well MW-
21D was installed to delineate the vertical extend of the petroleum impacted groundwater plume, and
confirm the results of the previous UVOST/LIF investigations. Groundwater samples were collected from
monitoring wells MW-10, MW-17, MW-18, MW-19, MW-20D, and MW-21D. The laboratory analytical results
indicated numerous petroleum constituents were detected at concentrations exceeding the respective 2L
Standards in MW-10, MW-18, MW-19, MW-20D, and MW-21D. Benzene was detected at concentrations
exceeding the respective GCL in MW-18, MW-19, MW-20D, and MW-21D. Methyl tert-butyl ether (MTBE)
was detected at a concentration exceeding the established GCL in MW-20D and MW-21D. LNAPL was
detected in RW-1, RW-2, and RW-4 at thicknesses of 0.17, 0.04, and 0.19 feet respectively. ATC also
collected a groundwater sample from SW-5 from an external spigot at the well house. The laboratory results
indicated the presence of naphthalene 1,1-dichloroethene, and 1,1-dichloroethane concentrations which
exceeded the laboratory reporting limits, but did not exceed the corresponding 2L Standards. ATC
recommended the installation of an additional Type III vertical extend well down-gradient from MW-21D,
additional groundwater sampling, and a feasibility study after vertical extend delineation to identify potential
remedial options.

This report documents the results of the January 2023 groundwater sampling event.

4.0 GROUNDWATER CHARACTERIZATION

4.1 GROUNDWATER LEVELS

Groundwater level measurements were collected from monitoring wells MW-2, MW-9, MW-10, MW-11, MW-
12, MW-13, MW-14, MW-16, MW-17, MW-18, MW-19, MW-20D, MW-21D, DW-1, DW-2, and recovery
wells RW-1, RW-2, RW-4, and RW-5 on January 19, 2023. Monitoring wells MW-4, MW-5, MW-6, MW-8,
and MW-15 could not be located. LNAPL was detected in RW-1, RW-2, and RW-4 at thicknesses of 0.07 feet,
0.27 feet, and 0.09 feet, respectively. Monitoring well construction details and current groundwater elevation
data are summarized in Table 2. Historical LNAPL measurements are summarized in Table 3. Depth to
groundwater measurements ranged from 6.90 feet bgs in MW-13 to 19.45 feet bgs in MW-20D. A groundwater
elevation contour map generated using the January 2023 groundwater elevation data is included as Figure 4.
Based on the groundwater elevation contour map, groundwater flow at the site is generally to the east and

southeast. Field notes from the site visit are included in Appendix A. Site photographs are presented in
Appendix B.

4.2 GROUNDWATER QUALITY

On January 19, 2023, groundwater samples were collected from monitoring wells MW-2, MW-9, MW-10,
MW-11, MW-12, MW-13, MW-14, MW-16, MW-17, MW-18, MW-19, MW-20D, MW-21D, DW-1, DW-2, and
recovery well RW-5. Samples were collected in laboratory-approved containers, packed in ice and delivered
under chain of custody protocol to SGS North America Inc., in Scott, Louisiana for analyses. Groundwater
samples were analyzed for volatile organic compounds (VOCs) by EPA Standard Method 6200B.

The laboratory analytical results indicated numerous petroleum constituents were detected at
concentrations exceeding the respective 2L Standards in monitoring wells MW-9, MW-10, MW-18, MW-19,
MW-20D, and MW-21D, DW-1, DW-2 and recovery well RW-5. Benzene was detected at concentrations
exceeding the respective GCL in MW-18, MW-19, MW-20D, and MW-21D. MTBE was detected at a
concentration exceeding the established GCL in MW-18, MW-20D, and MW-21D.

It should be noted that VOC concentrations in MW-10 have been historically attributed to an off-site, up
gradient source (Lewis Farm Supply) and not associated with the release at the site. The laboratory
analytical results from MW-21D indicate that the vertical extent of the petroleum impacted groundwater
plume is not fully delineated.

Current groundwater analytical data are summarized in Table 4 and historical groundwater analytical data
is summarized in Table 5. Natural attenuation parameters are included in Table 6. A dissolved benzene is
concentration contour map is included as Figure 5 and a map indicating additional constituents of concern
in groundwater is included as Figure 6.

The LNAPL thickness encountered in RW-1 and RW-4 was less than the thickness recorded during the
previous sampling event conducted in September 2022. However, LNAPL thickness in RW-2 was greater
than the previous sampling event conducted in September 2022. Historically, the highest LNAPL
thicknesses have been recorded when the groundwater elevation is low (see Figure 7). The laboratory
analytical report and chain-of-custody forms are included in Appendix C.

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 field blank sample indicated concentrations
of acetone, chlorobenzene, and ethyl alcohol above the method detection limits. The trip blank indicated
concentrations of acetone and ethyl alcohol above the method detection limits, but below the laboratory
reporting limits. 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. The laboratory QC report shows that an
internal blank was analyzed for each method that was used for the original samples. The laboratory fortified
blank (LFB) and laboratory control sample (LCS) data results were also provided for each analytical
method. Refer to the laboratory reports in Appendix D for details regarding QA results for the laboratory
samples and any noted exceptions. Overall, ATC concludes that the laboratory results are usable.

4.3 WATER SUPPLY WELLS

Based on the updated receptor survey performed in June 2017, there are nineteen water supply wells (SW-
1 through SW-19) that are located within 1,000 feet of the site. Municipal water is not available for the site
or the surround area. Water supply well locations are shown on Figure 3. Water supply well ownership
information is included in Table 1.

On January 19, 2023, ATC collected a groundwater sample from SW-5 from an external spigot at the well
house. The sample was collected in laboratory-approved containers, packed in ice and delivered under
chain-of-custody protocol to SGS for analyses. The sample was analyzed for VOCs by EPA Standard
Stalling’s Store

Method 6200B. The laboratory results indicated the presence of MTBE, 1,1-dichloroethene, and 1,1-
dichloroethane concentrations which exceeded the laboratory reporting limits but did not exceed the
corresponding 2L Standards. The analytical results for MTBE and 1,1-dichloroethane were reported as a
“J” value (estimated value below the reporting limits and exceeding the method detection limit). MTBE, 1,1-
dichloroethene, and 1,1-dichloroethane have been historically detected in water supply well SW-5 at
concentrations above the laboratory detection limits but below the 2L Standards. Water supply well SW-5
is located down-gradient from the impacted groundwater plume. Water supply well analytical results are
included in Table 7. The laboratory analytical report is included as Appendix C. The QA/QC measures
outlined in Section 4.2 are applicable to laboratory analytical data from the water supply well SW-5
groundwater sample.

5.0 CONCLUSIONS AND RECOMMENDATIONS

On behalf of the Trust Fund Branch of the UST Section, ATC has completed a Groundwater Monitoring
Report documenting a groundwater sampling event in January 2023 at the Stalling’s Store site located at
4708 Old U.S. Highway 64 East in Pilot, Franklin County, North Carolina. The findings from the recent and
historical assessment activities indicate the following:

 Groundwater samples were collected from recovery/monitoring wells RW-5, MW-2, MW-9, MW-10,
MW-11, MW-12, MW-13, MW-14, MW-16, MW-17, MW-18, MW-19, MW-20D, MW-21D, DW-1,
and DW-2, as well as water supply well SW-5. LNAPL was detected in RW-1, RW-2, and RW-4 at
thicknesses of 0.07 feet, 0.27 feet, and 0.09 feet, respectively.

 Results from the monitoring event indicated numerous petroleum constituents were detected at
concentrations exceeding the respective 2L Standards in RW-5, MW-9, MW-10, MW-18, MW-19,
MW-20D, and MW-21D, DW-1, and DW-2.

 Benzene was detected at concentrations exceeding the respective GCL in MW-18, MW-19, MW-
20D, and MW-21D. MTBE was detected at a concentration exceeding the established GCL in
MW-18, MW-20D, and MW-21D.

 The laboratory results for water supply well SW-5 indicated the presence of MTBE, 1,1-
dichloroethene, and 1,1-dichloroethane at concentrations which exceeded the laboratory detection
limits but did not exceed the corresponding 2L Standards. MTBE, 1,1-dichloroethene, and 1,1-
dichloroethane have been historically detected in water supply well SW-5 at concentrations above
the laboratory detection limits but below the 2L Standard; and

 The laboratory analytical results from MW-21D indicate that the vertical extent of the petroleum
impacted groundwater plume is not fully delineated.

Based on the results of the groundwater assessment, ATC recommends the following:

 The installation of additional Type III vertical extent wells down-gradient from monitoring well MW-21D,
locations depicted on Figure 5, to characterize the groundwater impacts in the deeper aquifer; and
 Performing a feasibility study upon the completion of vertical extent delineation to identify potential
remedial options for this site.
