2.0 EXECUTIVE SUMMARY

ATC Associates of North Carolina, P.C. (ATC) has completed a Groundwater Monitoring Report for the Texaco
Food Mart. This report documents a groundwater sampling event. The work is being performed based on a
September 25, 2023 Task Authorization (TA-01) 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 performed as part of State Lead Contract #N170522-B between NCDEQ and ATC.

The Texaco Food Mart site is located at 2618 Lake Wheeler Road in Raleigh, Wake County, North Carolina.
The site is currently occupied by Texaco Food Mart. Twelve monitoring wells are associated with the site.
Currently the site operates as an active retail fuel outlet and operates one 25,000-gallon gasoline UST and one
550-gallon kerosene UST. The former UST system consisted of two 10,000-gallon gasoline USTs and one
4,000-gallon diesel UST. The UST system was removed from the site on in June and July 2010.

Based on the results of the previous receptor survey, nineteen water supply wells are located within 1,000 feet
of the site, ten of which are used for drinking purposes. The closest water supply well used for drinking water
purposes (WSW-11) is located 460 feet down gradient from the site. An inactive water supply well (WSW-13)
is located 155 feet down gradient of the site. Municipal water is available through the City of Raleigh Public
Utilities Department to the site and surrounding properties.

On November 2, 2023, groundwater samples were collected from monitoring wells MW-1R, MW-3, MW-4,
MW-7, MW-8, MW-9, MW-10, MW-11, MW-12, MW-16, and DW-2R. Light non-aqueous phase liquid (LNAPL)
was not detected during the sampling event. Monitoring wells MW-1R, MW-3, MW-4, MW-11, and MW-12
contained petroleum-related constituents above the Title 15A NCAC 2L.0202 Standards (2L Standards). No
compounds were detected above Gross Contaminant Levels (GCLs). Water supply well samples collected
from 2223 Barnhill Drive (WSW-11), 2417 Kirk Avenue (WSW-15), and 2421 Kirk Avenue (WSW-16) indicated
petroleum hydrocarbon compounds at concentrations above the laboratory method detection limit, but below
the reporting limit; these constituents were flagged with a “J,” meaning they are an estimated concentration.
WSW-15 and WSW-16 had detections of toluene above the reporting limit but below the 2L groundwater
standard.

Overall, it appears that the groundwater impacts are migrating off-site to the southeast. Benzene was detected
in MW-12 for the third time. The presence of tert-amyl methyl ether (TAME) and tert-amyl alcohol (TAA) in MW-
3, MW-4, MW-11, MW-12, and DW-2R, and TAA in MW-3 may be attributed to the current site operations and
not the historical release.

Based on the results of the groundwater sampling event, ATC recommends the following:

 Continued sampling of the down gradient water supply wells WSW-10, WSW-11, and WSW-6 and
monitoring well network to determine plume stability. Performing additional air sparge and AFVR
events, if necessary;
 Installation of a downgradient monitoring well to the southeast of MW-12 to confirm the horizontal
extent of the contamination; and
 Review alternate remediation methods for site clean-up.

3.0 SITE DESCRIPTION

3.1 SITE CHARACTERIZATION

The Texaco Food Mart site is located at 2618 Lake Wheeler Road in Raleigh, North Carolina. Currently, one
single-story building exists on-site and is occupied by Texaco Food Mart. Currently the site operates as an
active retail fuel outlet and operates one 25,000-gallon gasoline UST and one 550-gallon kerosene UST. The
former UST Owner is Shree Rama, LLC. The former UST system consisted of two 10,000-gallon gasoline
USTs and one 4,000-gallon diesel UST. The UST system was removed from the site on in June and July
2010.

The site is bound by Lake Wheeler Road to the southeast with residential properties beyond, Kirk Avenue to
the northeast with multi-family residential buildings beyond, undeveloped land to the northwest and west with
a shopping center beyond. Surrounding properties are characterized by residential and commercial use. Based
on the results of the receptor survey, nineteen water supply wells are located within 1,000 feet of the site, ten
of which are used for drinking purposes. Municipal water is available through the City of Raleigh Public Utilities
Department to the site and surrounding properties. 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 potential
receptor map is included as Figure 3 and water supply well ownership information is summarized in Table 1.
The conceptual site model is included in Appendix A.

3.2 SITE BACKGROUND

In April 2007, MACTEC Environmental Engineering and Consulting, Inc. (MACTEC) performed an
environmental assessment at the site. Activities included the collection of soil and groundwater samples at
the property. Based on analytical results, soil samples exceeded the North Carolina Department of
Environmental Quality (NCDEQ) Action Level for total petroleum hydrocarbons (TPH) gasoline range
organics (GRO) and diesel range organics (DRO) and laboratory results for groundwater indicated
concentrations above the Title 15A NCAC 2L.0202 (2L) Standards. A Letter Report of Environmental
Services was prepared by MACTEC on May 10, 2007.

Agra Environmental, Inc. (Agra) submitted an Initial Abatement Report and Site Check Report to NCDEQ
on November 19, 2007, documenting soil results for samples collected around the UST system at the site.
Based on analytical results, soil had been impacted by the UST system at levels exceeding NCDEQ Action
Levels.

Agra submitted a Phase I Limited Site Assessment (LSA) to NCDEQ on February 13, 2008. During the
assessment, Agra installed monitoring well MW-1, collected soil and groundwater samples from MW-1, and
performed a receptor survey. Based on the LSA, soil and groundwater had been impacted at levels
exceeding corresponding standards and the site meets the criteria for a High risk classification due to the
presence of water supply wells used for drinking purposes located within 1,000 feet of the site.

Agra submitted a Comprehensive Site Assessment (CSA) to NCDEQ on February 17, 2009, documenting
the installation of monitoring wells MW-2 through MW-13, DW-1, and DW-2, a groundwater and water
supply well sampling event, and soil sampling results.

Between June 2010 and July 2010, Agra removed the USTs at the site (two 10,000-gallon gasoline USTs
and one 4,000-gallon UST) and performed over-excavation activities. During excavation activities,
approximately 2,179 tons of petroleum-impacted soil were removed from the site. Monitoring wells MW-1,
DW-1 and DW-2 were destroyed during excavation activities. An Initial Abatement Action Report and UST
System Closure Report was submitted to NCDEQ on August 13, 2008. One 25,000-gallon gasoline UST
one 550-gallon kerosene UST were installed in August 2010.

ATC Project No. STL3330901 NCDEQ State Lead Program
Agra submitted a Monitoring Report on February 7, 2011, documenting the installation of monitoring wells
MW-14 and MW-15, replacement wells MW-1R and DW-2R, and pilot test wells SVE-1, SVE-2, OW-1, OW-
2, AS and DPE as well as a comprehensive groundwater sampling event and pilot test.

A Corrective Action Plan (CAP) was submitted on May 18, 2011. The CAP recommended a vacuum-
enhanced fluid recovery system to address soil and groundwater contamination at the site. The CAP was
approved by NCDEQ on October 28, 2011.

A Baseline Monitoring Report was submitted on September 14, 2012, documenting groundwater sampling
activities conducted at the site prior to system startup. A Dual Phase Extraction System Startup Report was
submitted on March 27, 2013, documenting system installation and start-up that occurred on March 12,
2014. Due to contract issues between Agra and the responsible party, the remediation system was shut
down on May 4, 2013.

In October 2013, Shree Rama awarded an environmental services contract to ATC for continuing
environmental services at the site. Between November 2013 and January 2015 ATC performed two
groundwater sampling events, performed an updated receptor survey and operated the dual phase
groundwater treatment system. In 2015, ATC declined to continue providing environmental services for
Shree Rama due to contract issues.

On November 30, 2018, ATC submitted a Federal/State Lead Groundwater Monitoring Report documenting
the results for a receptor survey, a groundwater and water supply well sampling event, and on-site
remediation system inspection. Based on the results of the receptor survey, twenty-one water supply wells
are located within 1,000 feet of the site, twelve of which are used for drinking purposes. Municipal water is
available through the City of Raleigh Public Utilities Department to the site and surrounding properties.
Laboratory analytical results from the sampling event indicated petroleum hydrocarbon compounds at
concentrations exceeding North Carolina 2L Groundwater Standards (2L Standards) in monitoring wells MW-
1R, MW-3, MW-4, MW-9, and MW-12. The water supply well sample did not exhibit concentrations above the
laboratory detection limits. The remediation system inspection revealed that, visually, the system
components appear to be in good condition. However, without connecting the system to a power supply,
the functionality of each component cannot be verified.

On May 9, 2019, ATC submitted a Federal/State Lead Groundwater Monitoring Report documenting the
results for a groundwater and water supply well sampling event, and on-site remediation system inspection.
Laboratory analytical results from the sampling event indicated petroleum hydrocarbon compounds at
concentrations exceeding North Carolina 2L Groundwater Standards (2L Standards) in monitoring wells MW-
3 and MW-9. Laboratory analytical results from the sampling event also indicated petroleum hydrocarbon
compounds at concentrations below the 2L Standards in WSW-16. No compounds were detected in the
samples collected from WSW-6 and WSW-15. Based on the results of the inspection groundwater sampling
results, it was determined that the system components appear to be in good condition and that the system
could be modified for use at other State Lead sites where groundwater remediation is necessary. ATC
recommended the installation of a monitoring well to delineate the groundwater impact and to confirm that
the release at the site is not impacting off-site properties in addition to semi-annual sampling of the water
supply wells.

On April 2, 2020, ATC submitted a Federal/State Lead Groundwater Monitoring Report documenting the
results for a groundwater and water supply well sampling event, and on-site remediation system inspection.
Laboratory analytical results from the sampling event indicated petroleum hydrocarbon compounds at
concentrations exceeding North Carolina 2L Groundwater Standards (2L Standards) in monitoring wells MW-
3. Laboratory analytical results from the sampling event also indicated petroleum hydrocarbon compounds at
concentrations below the 2L Standards in MW-4, MW-9, MW-11, MW-16, and DW-2R. No compounds were
detected in the samples collected from WSW-6, WSW-15, and WSW-16.

On February 25, 2021, ATC submitted a Notice of Intent to Construct or Operate Injection Wells to the
NCDEQ Division of Water Resources for the installation of air sparge well AS-1. On March 21, 2021 deemed
Texaco Food Mart
November 29, 2023
Page 5 of 8

ATC Project No. STL3330901 NCDEQ State Lead Program
permit number W10501071 was issued by NCDEQ for the air sparge installation and air sparge events. On
March 22, 2021, ATC supervised the installation of air sparge well AS-1. AS-1 was installed adjacent to
MW-3. The purpose for the installation of AS-1 is to conduct enhanced air sparge events to volatilize the
petroleum compounds in the subsurface for removal by concurrent AFVR activities.

On March 24, 2021, April 28, 2021, and May 20, 2021 ATC supervised the AFVR and air sparge events at
the site. Overall, a total of 1,836 gallons of petroleum impacted groundwater and 3.29 gallons of petroleum
impacted vapor were recovered during the AFVR events. A comparison of total benzene concentrations in
MW-3 from the January 17, 2020 sampling event, (prior to the AFVR activities) to the August 2, 2021, sampling
event showed that benzene concentrations were reduced by 46% and MTBE concentrations were reduced by
75% indicating that the AFVR was successful.

On September 15, 2021, ATC submitted a Federal/State Lead Groundwater Monitoring Report
documenting the results for a groundwater and water supply well sampling event. Laboratory analytical
results from the sampling event indicated petroleum hydrocarbon compounds at concentrations exceeding
North Carolina 2L Groundwater Standards (2L Standards) in monitoring wells MW-1R, MW-3, MW-4 and MW-
12. Laboratory analytical results from the sampling event also indicated petroleum hydrocarbon compounds at
concentrations below the 2L Standards in WSW-16. No compounds were detected in the samples collected
from WSW-6 and WSW-15.

On November 27, 2021, ATC secured a water connection and well abandonment agreement from Mr. Marty
Hester, owner of water supply well WSW-4 (2226 Barnhill Drive). The property serviced by WSW-4 includes
a private residence.

On August 25, 2022, Raleigh Plumbing & Heating, Inc., installed a waterline from the City of Raleigh
municipal water tap to the residence located at 2226 Barnhill Drive in Raleigh, North Carolina. The WSW-
4 equipment was removed, and the crawlspace waterlines were re-piped. The City of Raleigh completed
the water meter installation on August 30, 2022.

On September 9, 2022, ATC obtained a permit (Permit # GW-088556-2022) from Wake County to abandon
water supply well WSW-4. Additionally, as the well head was located below grade, the property owner
agreed to locate and uncover the well head prior to the start of work.

On November 16, 2022, Regional Probing Services, a NC-certified well contractor (Certification Number
3322) abandoned water supply well WSW-4, located at 2226 Barnhill Drive, Raleigh, North Carolina. The
well had a total depth of 96 feet and a diameter of 6 inches. The associated piping was removed from the
well, and the well casing was filled with hydrated bentonite and capped with concrete. Topsoil was then
placed on top of the former well head to grade, followed by seed and straw. ATC personnel and an inspector
from Wake County were onsite during the abandonment activities.

On March 8, 2023, ATC submitted a Federal/State Lead Groundwater Monitoring Report documenting the
results for a groundwater and water supply well sampling event. Laboratory analytical results from the
sampling event indicated petroleum hydrocarbon compounds at concentrations exceeding North Carolina 2L
Groundwater Standards (2L Standards) in monitoring wells MW-1R, MW-3, MW-4 and MW-12. Laboratory
analytical results from the sampling event also indicated petroleum hydrocarbon compounds at concentrations
below the 2L Standards in WSW-16. No compounds were detected in the samples collected from WSW-6
and WSW-15.

This report documents the results of the November 2023 groundwater and water supply well sampling
event.

4.0 GROUNDWATER ASSESSMENT ACTIVITIES

4.1 GROUNDWATER LEVELS

Groundwater level measurements were collected from monitoring wells MW-1R, MW-3, MW-4, MW-7, MW-8,
MW-9, MW-10, MW-11, MW-12, MW-16, and DW-2R on November 2, 2023. Light non-aqueous phase liquid
(LNAPL) was not detected during the sampling event. Monitoring well construction details and current and
historical groundwater elevation data are summarized in Table 2. Depth to groundwater measurements ranged
from 27.88 feet bgs in MW-8 to 34.02 feet bgs in MW-9. A groundwater elevation contour map is included as
Figure 4. Based on the January 2023 field measurements, groundwater flows southeast across the site. Field
notes are included in Appendix B. Site photographs are included in Appendix C.

4.2 GROUNDWATER QUALITY

On November 2, 2023, groundwater samples were collected from monitoring wells MW-1R, MW-3, MW-4,
MW-7, MW-8, MW-9, MW-10, MW-11, MW-12, MW-16, and DW-2R. Samples were collected in laboratory-
approved containers, packed in ice and delivered under chain-of-custody protocol to SGS North America
Inc. (SGS) in Scott, Louisiana for analyses. Groundwater samples were analyzed for volatile organic
compounds (VOCs and oxygenates) by Environmental Protection Agency (EPA) Method 6200B to include
ethanol and oxygenates.

Laboratory analytical results of the sampling event indicate petroleum hydrocarbon compounds at
concentrations exceeding the 2L Standards in monitoring well MW-1R, MW-3, MW-4, MW-11 and MW-12.

Monitoring well MW-1R contained concentrations of benzene at 14.0 micrograms per liter (μg/L) and
naphthalene at 84.0 μg/L above the 2L Standards. Monitoring well MW-3 contained concentrations of benzene
at 12.8 μg/L, MTBE at 91.1 µg/L, tert-amyl alcohol (TAA) at 79.2 μg/L, and 1,2,3-trichloropropane at 0.21 µg/L
above the 2L Standards. Monitoring well MW-4 contained concentrations of naphthalene at 18.8 μg/L and
1,2,3-trichloropropane at 0.89 µg/L above the 2L Standards. Monitoring well MW-11 contained concentrations
of MTBE at 43.8 µg/L above the 2L Standards. Monitoring well MW-12 contained concentrations of benzene
at 52.9 µg/L, MTBE at 803 µg/L, naphthalene at 15.3 μg/L, and 1,2-dichloroethane at 4.1 µg/L above the 2L
Standards. No compounds were detected above GCLs. Current groundwater analytical results are
summarized in Table 3 and historical groundwater analytical results are summarized in Table 4. Natural
attenuation parameters are included as Table 5. Dissolved benzene and MTBE isoconcentration contour
maps are included as Figures 5 and 6, respectively. A figure showing contaminants of concern in
groundwater is included as Figure 7. The laboratory analytical report and chain-of-custody forms are
included in Appendix D.

Overall, it appears that the groundwater impacts are migrating off-site to the southeast. An increase in benzene
was detected in MW-12 for the second time. The presence of tert-amyl methyl ether (TAME) and TAA in MW-
3 MW-4, MW-11, MW-12, and DW-2R may be attributed to the current site operations and not the historical
release.

As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of the
laboratory report was conducted. A laboratory prepared trip blank (TB) was analyzed. Ethyl alcohol and
toluene were detected. Ethyl alcohol is a common laboratory contaminant. The presence of the toluene
was reconfirmed by analysis, and no additional issues were identified by the lab. During the review, it was
concluded that samples were received by the laboratory in acceptable condition and properly preserved.
The samples were analyzed within the correct holding times, and the chain of custody was properly
completed by all parties. The laboratory QC report shows 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,
Texaco Food Mart

ATC Project No. STL3330901 NCDEQ State Lead Program
ATC concludes that the laboratory results are usable, and any exceptions do not significantly impact the
conclusions presented in this report.

4.3 WATER SUPPLY WELL SAMPLING

On November 2, 2023, samples were collected from the water supply wells located at 2223 Barnhill Drive
(WSW-11), 2417 Kirk Avenue (WSW-15), and 2421 Kirk Avenue (WSW-16). Samples were collected in
laboratory-approved containers, packed in ice and delivered under chain-of-custody protocol to SGS. The
water supply well samples were analyzed for VOCs by EPA Method 6200B. Current and historical water
supply well analytical results are summarized in Table 6.

Water supply well samples collected from WSW-11, WSW-15, and WSW-16 indicated petroleum
hydrocarbon compounds at concentrations above the laboratory method detection limit (MDL), but below the
reporting limit (RL); these constituents were flagged with a “J,” meaning they are an estimated concentration.
WSW-15 and WSW-16 had detections of toluene below the 2L Standard. Toluene has not been detected in
WSW-15 before this sampling event, and has not been detected since 2019 in WSW-16. Toluene was also
detected in WSW-11 above the MDL and below the RL, ATC sampled this well for the first time during the
November sampling event. However, it should be noted toluene was detected in the laboratory prepared trip
blank, therefore these toluene detections may be a laboratory artifact. Chloroform was detected in WSW-16
above the MDL, but below the RL. MTBE was also detected in WSW-15 and WSW-16 above MDL, but below
the RL. The laboratory analytical report and chain-of-custody forms are included in Appendix D.

5.0 CONCLUSIONS AND RECOMMENDATIONS

On behalf of the Trust Fund Branch of the UST Section, ATC has completed a State-Lead Groundwater
Monitoring Report documenting a groundwater and water supply well sampling event for the Texaco Food
Mart site is located at 2618 Lake Wheeler Road in Raleigh, Wake County, North Carolina.

 On November 2, 2023, groundwater samples were collected from monitoring wells MW-1R, MW-3,
MW-4, MW-7, MW-8, MW-9, MW-10, MW-11, MW-12, MW-16, and DW-2R. LNAPL was not detected
during the sampling event;

 Monitoring wells MW-1R, MW-3, MW-4, MW-11 and MW-12 contained petroleum-related constituents
above the 2L Standards. Additional petroleum-related constituents were also detected at
concentrations above the laboratory detection limits but below the 2L Standards in various monitoring
wells;

 No compounds were detected above the GCLs; and

 Water supply well samples collected from WSW-11, WSW-15, and WSW-16 indicated petroleum
hydrocarbon compounds at concentrations above the laboratory method detection limit, but below the
reporting limit; these constituents were flagged with a “J,” meaning they are an estimated
concentration. WSW-15 and WSW-16 had detections of toluene and MTBE below the 2L Standard.

Overall, it appears that the groundwater impacts are migrating off-site to the southeast. Benzene was detected
in MW-12 for the third time. The presence of TAME and TAA in MW-3, MW-4, MW-11, MW-12, and DW-2R,
and TAA in MW-3 may be attributed to the current site operations and not the historical release.
