2.0 EXECUTIVE SUMMARY

ATC Associates of North Carolina, P.C. (ATC) has completed a Groundwater Monitoring Report (GMR) for
the Sav-A-Ton 79 site located at 2270 North Garnett St, Henderson, Vance County, North Carolina. This
report documents a monitoring well sampling event conducted at the site in May 2023. The GMR was
performed based on the Task Authorization (TA-01), dated April 25, 2023, 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 the State Lead Contract #N70522-B
between NCDEQ and ATC.

The Sav-A-Ton 79 site is located at 2270 North Garnett St, Henderson, Vance County, North Carolina. The
site is improved with a single-story concrete building/convenience store and gasoline service station with
an associated UST system and dispenser island canopies. Municipal water is available to the area, and
one active water supply well (WSW-5) is located approximately 670 feet northwest of the site. The owner
of WSW-5 has signed an agreement to connect to the available municipal water supply and for WSW-5 to
be used for irrigation purposes only.

On May 16, 2023, groundwater samples were collected from wells MW-1R, MW-2, MW-3, MW-4, MW-6,
MW-7, MW-8, MW-10, MW-11, MW-12, MW-13, MW-14, DW-1R, AS-1, and SVE-1. Light non-aqueous
phase liquid (LNAPL) was not detected during the sampling event. Laboratory analytical results indicated
the presence of petroleum constituents exceeding the 15A NCAC 2L. 0202 Groundwater Quality Standards
(2L Standards) in monitoring wells MW-1R, MW-4, MW-8, MW-11, MW-12, MW-14, AS-1, and SVE-1.
Benzene concentrations in MW-1 (7,810 µg/L) and MW-4 (8,080 µg/L) exceeded the gross contaminant
levels (GCLs).

A comparison of the current analytical results (May 2023) to the results of the previous sampling event
(March 2022) indicates an increase in contaminant concentrations in monitoring wells MW-8, MW-11, MW-
14, and AS-1. However, concentrations in MW-1R, MW-4, MW-12, DW-1R, and SVE-1 have slightly
decreased since the previous sampling event. Based on the groundwater results, the groundwater impact
is mostly defined horizontally and vertically.

Chlorinated solvents previously detected in March 2022 were not detected during the May 2023 event and
their historical presence may indicate a possible off-site source impacting the groundwater quality at the
site.

The current site risk (H312A) is based on the presence of one potable water supply well (WSW-5),
approximately 670 ft from the source area and petroleum concentrations in MW-1R and MW-4 exceeding
the GCLs. Based on the Conceptual Site Model (Appendix A), site closure may be obtained by connecting
the residence associated with WSW-5 to the available public water supply, restricting WSW-5 to irrigation
use only, and reducing the dissolved concentrations in MW-1R and MW-4 to below the GCLs. In order to
achieve site closure, ATC recommends the following:

 Connect the residence associated with WSW-5 to the existing municipal water supply and restrict
the WSW-5 to irrigation use;
 Perform an air-sparge enhanced mobile multi-phase extraction (MMPE) event, utilizing MW-1R and
MW-4 as extraction points, in order to reduce the dissolved concentrations at the site.
 30-days following the MMPE event, a groundwater monitoring event should be performed to
evaluate the effectiveness of the MMPE event.

3.0 SITE DESCRIPTION

3.1 SITE CHARACTERIZATION

The Sav-A-Ton #79 site is located at 2270 North Garnett Street in Henderson, Vance County, North
Carolina. One 8,000-gallon UST and two 6,000-gallon USTs were previously in operation at the site and
Sav-A-Ton #79
August 03, 2023
Page 4 of 10

ATC Project No. STL2318602 NCDEQ State Lead Program
subsequently removed in September 1990. The site is currently an active Citgo gas station and operates
three 10,000-gallong gasoline USTs, one 10,000-gallon diesel UST, and one 4,000-gallon Kerosene UST.

Twelve Type II monitoring wells (MW-1R through MW-4, MW-6 through MW-8, and MW-9 through MW-14),
one Type III monitoring well (DW-1R), one air sparge well (AS-1), and one soil-vapor-extraction well (SVE-
1) are associated with the site. Municipal water is available to the area; however, one active potable water
supply well (WSW-5) is currently located approximately 670 feet from the site. The owner of WSW-5 has
signed an agreement to connect to the available municipal water supply and for WSW-5 to be used for
irrigation purposes only. 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. Water supply well ownership
information is included in Table 1. Water supply well locations are depicted in Figure 3.

3.2 SITE BACKGROUND

The site is an active Citgo gasoline station and convenience store. According to historical records, one
8,000-gallon UST and two 6,000-gallon USTs were installed at the site in 1978 and subsequently removed
in September 1990. In September 2000, S&ME conducted a Phase II Environmental Site Assessment
(Phase II ESA) at the site. Laboratory analysis of soil and groundwater samples collected during the Phase
II ESA reported petroleum related compounds at concentrations above their respective soil-to-groundwater
maximum soil contaminant concentrations (MSCCs) for soils and Title 15A NCAC 02L .0202 Groundwater
Quality Standards (2L Standards) for groundwater.

In October 2001, S&ME conducted a Phase II Limited Site Assessment (LSA) for the site. During the Phase
II activities, S&ME installed three shallow monitoring wells (MW-1R, MW-2, and MW-3) and one deep well
(DW-1R). During groundwater sampling activities, light non-aqueous phase liquid (LNAPL) was observed
in monitoring well MW-1R near the western most dispenser island. The site was assigned a high risk ranking
due to the presence of active potable water supply wells within 1,000-feet of the site.

Two Aggressive Fluid and Vapor Recovery (AFVR) events were conducted in December 2001 and July
2002 to remove LNAPL from monitoring well MW-1R. In August 2002, S&ME completed a Comprehensive
Site Assessment (CSA). During the CSA activities, monitoring wells MW-4, MW-5, MW-6, and MW-7 were
installed. In April 2002, S&ME completed a Corrective Action Plan (CAP) for the site. The CAP
recommended using air sparging and soil vapor extraction as a means of remediation.

In April 2006, Withers and Ravenel (W&R) conducted a groundwater monitoring event and updated receptor
survey at the site. Laboratory analysis of groundwater samples collected from monitoring wells MW-1R and
MW-4 reported targeted analytes at concentrations above their respective 2L Standards and Gross
Contamination Levels (GCLs). 2L Standard exceedances were also reported in the groundwater sample
collected from monitoring well DW-1R. The updated receptor survey identified nine water supply wells within
1,500 feet of the site. Two water supply wells (WSW-5 and WSW-6) were identified as sole- source water
supply wells located within 1,000 feet of the site. WSW-5 and WSW-6 both serviced several residences
owned by Mr. George Wortham.

In March 2008, W&R installed groundwater monitoring wells MW-8 and MW-9 and conducted a
groundwater monitoring event. Monitoring well MW-5 was noted as being destroyed. LNAPL was reported
in monitoring well MW-4. A soil assessment was conducted to attempt to determine the source of the LNAPL
but was discontinued when a diesel product line was damaged during hand-auger boring activities. The
product line was repaired and impacted soils were removed. Five water-supply wells (WSW-1, WSW-5,
WSW-6, WSW-7, and WSW-9) were sampled in May 2008. A detection was noted in WSW-7 but it was
determined that this well was used for an industrial water supply at a concrete plant to the southwest of the
site.

In December 2010, Terraquest installed monitoring wells MW-10, MW-11, and MW-12 and subsequently
conducted a groundwater monitoring event. Terraquest identified LNAPL in monitoring wells MW-4 and
Sav-A-Ton #79

ATC Project No. STL2318602 NCDEQ State Lead Program
MW-12 and 2L Standards violations from the groundwater samples collected from monitoring wells MW-
1R and MW-8.

In February 2013, Terraquest conducted a groundwater monitoring event at the site. Water-supply wells
WSW-5 and WSW-6 were sampled during the event. Benzene was reported above its GCL from
groundwater sample MW-4. Chloroform and methyl-tert-butyl ether (MTBE) were reported below their
respective 2L Standards from water-supply well WSW-5. 1,2-dichloroethane was detected in WSW-6 below
the 2L Standard.

On October 8, 2014, ECS conducted a groundwater monitoring event at the site. A groundwater sample
was also collected from water supply well WSW-5. ECS measured LNAPL in monitoring wells MW-4 and
MW-12. Laboratory analysis of the groundwater sample collected from monitoring well MW-1R reported
benzene at a concentration above its 2L Standards and GCL. Laboratory analysis of the groundwater
sample collected from water supply well WSW-5 reported chloroform at a concentration above its laboratory
reporting limit but below its 2L Standards.

On May 4, 2015, ECS contracted with Zebra Environmental & Industrial Services (Zebra) to conduct an
AFVR event at the site using monitoring wells MW-1R and MW-4 as extraction points. On May 13 and 14,
2015, two groundwater monitoring wells (MW-13 and MW-14) were installed downgradient of the
constituent plume followed by a sampling event. Laboratory analysis detected GCL exceedances in MW-
1R and MW-4. Laboratory analysis of the groundwater sample collected from water supply well WSW-5
reported chloroform at a concentration above its laboratory reporting limit but below its 2L Standards.

On March 9, 2016, ECS conducted a groundwater monitoring event at the site. Groundwater samples were
also collected from water supply wells WSW-5 and WSW-6. Additionally, ECS installed oxygen releasing
socks (O-SOX) in monitoring wells MW-1R, MW-4, MW-8, and MW-14. Laboratory analysis reported
benzene at a concentration above its GCL in the groundwater samples collected from monitoring wells MW-
1R and MW-4. During the 2016 event, ECS contacted the owner of WSW-5 and WSW-6, Mr. Wortham. Mr.
Wortham stated that WSW-6 does not exist and that WSW-5 supplied water to all residences previously
associated with WSW-5 and WSW-6. Mr. Wortham also agreed to abandon WSW-5 and connect to the
municipal water supply.

On June 12, 2017, ECS collected groundwater samples from the associated monitoring wells. Additionally,
ECS removed and replaced O-SOX in monitoring wells MW-1R, MW-4, MW-8, and MW-14. Laboratory
analysis reported benzene at a concentration above its GCL in monitoring wells MW-1R and MW-4. Water
supply wells were not sampled during this sampling event.

On June 20 and 21, 2018, ECS collected groundwater samples from the associated monitoring wells and
water supply well WSW-5. Additionally, ECS removed and replaced O-SOX in monitoring wells MW-1R,
MW-4, MW-8, and MW-12. Laboratory analysis reported benzene at a concentration above its GCL in
monitoring wells MW-4 and DW-1R. Benzene had not been previously detected in deep monitoring well
DW-1R since 2010 (6.5 micrograms per Liter (µg/L). Upon receiving the laboratory results from the June
2018 sampling event, ECS determined it was possible monitoring wells MW-1R and DW-1R were mistaken
for other monitoring wells at the site. ECS concluded monitoring well MW-1R was sampled and submitted
to the laboratory as monitoring well DW-1R and either monitoring wells SVE-1 or AS-1 were sampled and
submitted to the laboratory as monitoring MW-1R. The laboratory results from this sampling event
accurately reflect the historical laboratory results previously confirmed. Concentrations of targeted analytes
were not reported above laboratory reporting limits, with exception to chloroform, in the groundwater sample
collected from water supply well WSW-5.

During the June 2018 sampling event, ECS was informed that the previous owner of WSW-5, Mr. Wortham,
had passed away, and the property had been sold. The new owner of the residences associated with water
supply well WSW-5, Mr. Robert Torres, stated that he was willing to connect the property to the municipal
water system, and granted written consent for ECS to sample the groundwater from his water supply well
WSW-5.

On February 12, 2019, ECS contracted with Zebra to conduct an AFVR event at the site using monitoring
wells MW-1R and MW-4 as extraction points. On February 27 and 28, 2019, ECS collected groundwater
samples from the associated monitoring wells and water supply well WSW-5. Additionally, ECS deployed
new O-SOX remedial devices in monitoring wells MW-1R, MW-4, MW-8, DW-1R, SVE-1, and AS-1
following sampling activities. Laboratory analysis reported benzene at a concentration above its GCL in
MW-1R and MW-4. The laboratory results for WSW-5 were below the laboratory detection limits.

On July 17, 2019, ECS conducted a hydraulic conductivity test to determine hydraulic properties of the
shallow aquifer at monitoring wells MW-1R and MW-4 and performed fate and transport modeling.
Predictive computer modeling using conservative input values indicate that the existing plume of petroleum-
related compounds is not expected to be present above laboratory reporting limits or applicable 2L
Standards no more than 300 feet from the ‘source area’ (monitoring well MW-1R and MW-4) over a period
of 100 years. Therefore, this model demonstrates water supply well WSW-5, located approximately 670
feet downgradient and to the northwest of the site, is not expected to be impacted by this release.

On February 17, 2020, ECS collected groundwater samples from the associated monitoring wells and water
supply well WSW-5. ECS was unable to locate monitoring MW-9 with a metal detector and historical site
and aerial photographs; therefore, was unable to collect a groundwater sample. ECS installed new O-SOX
remedial devices in monitoring wells MW-1R, MW-4, MW-8, DW-1R, SVE-1, and AS-1 following sampling
activities. Laboratory analysis reported benzene at a concentration above its GCL in MW-1R and MW-4.
Chloroform was detected as an estimated J value in WSW-5 below the 2L Standards.

On July 30, 2020, ECS contracted with Hazmat Emergency Response and Remediation, Inc. (HERR) to
conduct an AFVR event at the site using monitoring wells MW-1R and MW-4 as extraction points.
Approximately 3,000-gallons of liquid was removed from the two monitoring wells. On August 17 and 18,
2020, ECS collected groundwater samples from the monitoring well network and water supply well WSW-
5. ECS was unable to locate monitoring MW-9 during the event. Additionally, ECS removed O-SOX
remedial devices prior to the AFVR and sampling in monitoring wells MW-1R, MW-4, MW-8, and MW-12
and installed new O-SOX remedial devices in monitoring wells MW-1R, MW-4, MW-8, DW-1R, SVE-1 and
AS-1 following the sampling activities. Laboratory analysis reported benzene at a concentration above its
GCL in MW-1R and MW-4. Laboratory analysis reported several targeted analytes at concentrations above
their respective 2L Standards but below their respective GCLs in the groundwater samples collected from
monitoring wells AS-1, SVE-1, MW-1R, MW-6, MW-8, MW-10 through MW-14, and DW-1R. Chloroform
was detected as an estimated J value in WSW-5 below the 2L Standards.

On April 7, 2021, ATC collected groundwater samples from the associated monitoring wells. Monitoring
well MW-9 could not be located during the event and is assumed destroyed. ATC was unable to contact
the owner of WSW-5 to obtain access to WSW-5 prior to or during the sampling event. LNAPL was not
detected during the sampling event. Laboratory analysis reported several targeted analytes at
concentrations above their respective 2L Standards in monitoring wells MW-1R, MW-4, MW-8, MW-12, AS-
1, and SVE-1. Laboratory analysis reported benzene at a concentration above the GCLs in MW-1R.

On March 10, 2022, ATC supervised an air sparge enhanced aggressive fluid vapor recovery (AFVR) event
at the site, utilizing MW-1R and SVE-1 as extraction points. On March 24, 2022, ATC collected groundwater
samples from the associated monitoring wells. LNAPL was not detected during the sampling event.
Laboratory analysis reported several targeted analytes at concentrations above their respective 2L
Standards in monitoring wells MW-1R, MW-4, MW-8, MW-12, MW-14, DW-1R, AS-1, and SVE-1.
Laboratory analysis reported benzene at a concentration above the GCLs in MW-1R and MW-4. Following
the completion of the sampling event, the well covers associated with MW-11 and DW-1R were replaced
by a licensed driller.

4.0 GROUNDWATER CHARACTERIZATION

4.1 GROUNDWATER LEVELS

ATC personnel conducted a groundwater sampling event at the site on May 16, 2023. Groundwater level
measurements were recorded from wells MW-1R, MW-2, MW-3, MW-4, MW-6, MW-7, MW-8, MW-10, MW-
11, MW-12, MW-13, MW-14, DW-1R, AS-1, and SVE-1. Monitoring well construction details and current
and historical groundwater elevation data are summarized in Table 2. Field parameter data including
temperature, dissolved oxygen, conductivity, pH, and oxygen reduction potential were recorded during the
sampling event and are included in Table 3. Field parameters were not recorded in monitoring wells MW-
1R and MW-4 as the purged water from these wells contained a strong petroleum odor. LNAPL was not
detected during the sampling event. Depth to groundwater measurements ranged from 6.37 feet bgs in
SVE-1 to 9.93 feet bgs in MW-10. Based on the monitoring well construction details (included in Table 2)
the groundwater surface was measured above the well screen intervals for the Type II monitoring wells
MW-1R, MW-3, MW-6, MW-7, MW-10, MW-11, MW-12, MW-13 and MW-14. A groundwater elevation
contour map generated using the May 16, 2023, elevation data is included as Figure 4. The groundwater
flow direction observed during the May 16, 2023, groundwater sampling event was generally to the
southwest. Field notes from the May 16, 2023, sampling event are included in Appendix B. Site
photographs are included in Appendix C.

4.2 GROUNDWATER QUALITY

4.2.1 Monitoring Wells

On May 16, 2023, groundwater samples were collected from wells MW-1R, MW-2, MW-3, MW-4, MW-6,
MW-7, MW-8, MW-10, MW-11, MW-12, MW-13, MW-14, DW-1R, AS-1, and SVE-1. During sampling
activities, a three-volume well purge was implemented prior to groundwater sample collection to ensure
collection of a representative groundwater sample. A field blank sample was also collected on May 16,
2023, as part of the groundwater sampling event. 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 Method 6200B + oxygenates. A trip blank sample was also analyzed by 6200B.

Laboratory analytical results indicated the presence of petroleum constituents exceeding the 2L Standards
in monitoring wells MW-1R, MW-4, MW-8, MW-11, MW-12, MW-14, AS-1, and SVE-1. Benzene
concentrations in MW-1 (7,810 µg/L) and MW-4 (8,080 µg/L) exceeded the GCLs. Current groundwater
analytical data is summarized in Table 4. Historical groundwater analytical data is summarized in Table 5.
A dissolved benzene isoconcentration contour map is included as Figure 5. A map showing additional
contaminants of concern are included as Figure 6. The laboratory analytical report and chain-of-custody
forms are included in Appendix D.

A comparison of the current analytical results (May 2023) to the results of the previous sampling event
(March 2022) indicates mostly stable groundwater concentrations. Groundwater concentrations in MW-1R,
MW-4, MW-12, DW-1R, and SVE-1 have slightly decreased since the previous sampling event.

Tert-Amyl Alcohol (TAA) was detected in MW-1R, MW-4, MW-8, MW-13, and AS-1 at concentrations
exceeding the 2L Standards. Tert-Butyl Alcohol (TBA) was detected in MW-1, MW-13, and AS-1 at
concentrations exceeding the 2L Standards. TAA and TBA concentrations have been historically detected
at the site.

During the previous sampling event conducted in March 2022 concentrations of tetrachloroethylene,
trichloroethylene, cis-1,2-dichloroethylene, trans-1,2-dichloroethylene, 1,1,2,2-tetrachloroethane, and
1,1,2-trichloroethane were detected at the site. Additionally, 1,1,2,2-tetrachloroethane, and 1,1,2-
Sav-A-Ton #79
August 03, 2023
Page 8 of 10

ATC Project No. STL2318602 NCDEQ State Lead Program
trichloroethane concentrations exceeded the GCLs in MW-4 in March 2022. Concentrations of
tetrachloroethylene have previously been detected in MW-1R during a sampling event in June 2018.
However, prior to the March 2022 event or in the subsequent May 2023 event, trichloroethylene, cis-1,2-
dichloroethylene, trans-1,2-dichloroethylene, 1,1,2,2-tetrachloroethane, and 1,1,2-trichloroethane have not
been detected at the site. Historical monitoring well analytical results are included in Table 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 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. No constituents were detected in the field blank sample. However, Acetone,
toluene, chlorobenzene, ethyl alcohol, methylene chloride, methyl ethyl ketone, and tert-butyl alcohol were
detected in the trip blank sample, below their respective 2L Standards. Acetone, toluene, chlorobenzene,
methyl ethyl ketone, and tert-butyl alcohol were detected in at least one monitoring well sample, therefore
the results for these compounds may be biased high. Overall, ATC concludes that the laboratory results
are usable and any exceptions do not significantly impact the conclusions presented in this report. Refer to
the laboratory reports in Appendix D for details regarding QA results for the laboratory samples and any
noted exceptions.

4.2.3 Water Supply Wells

Previous assessment activities conducted at the site identified one active potable water supply well (WSW-
5) within 1,000 feet of the site. A trace concentration of chloroform, below the 2L Standards was detected
in WSW-5 in August 2020. On April 1, 2022, the owner of WSW-1, Mr. Robert Torres signed an agreement
allowing the associated residence to be connected to the available public water supply and WSW-5 to be
used only for irrigation purposes. If Mr. Torres’ property is connected to municipal water, the site risk can
be lowered to intermediate since his water supply well is located 670 feet from the site.

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 monitoring event for the Sav-A-Ton #79 site, located at 2270 North
Garnett Street in Henderson, Vance County, North Carolina. The findings from the recent assessment
activities indicate the following:

 Groundwater samples were collected from monitoring wells MW-1R, MW-2, MW-3, MW-4, MW-6,
MW-7, MW-8, MW-10, MW-11, MW-12, MW-13, MW-14, DW-1R, AS-1, and SVE-1. LNAPL was
not detected during the sampling event;

 Laboratory analytical results indicated the presence of petroleum constituents exceeding the 2L
Standards in monitoring wells MW-1R, MW-4, MW-8, MW-11, MW-12, MW-14, AS-1, and SVE-1.
Benzene concentrations exceeded the GCLs in MW-1R and MW-4;

 Chlorinated solvents previously detected in March 2022 were not detected during the May 2023
event and may indicate a possible off-site source impacting the groundwater quality at the site; and

 A comparison of the current analytical results (May 2023) to the results of the previous sampling
event (March 2022) indicates mostly stable groundwater concentrations. Groundwater
concentrations in MW-1R, MW-4, MW-12, DW-1R, and SVE-1 have slightly decreased since the
previous sampling event.

The current site risk (H312A) is based on the presence of one potable water supply well (WSW-5),
approximately 670 ft from the source area and petroleum concentrations in MW-1R and MW-4 exceeding

the GCLs. Based on the Conceptual Site Model, site closure may be obtained by connecting the residence
associated with WSW-5 to the available public water supply, restricting WSW-5 to irrigation use only, and
reducing the dissolved concentrations in MW-1R and MW-4 to below the GCLs. In order to achieve site
closure, ATC recommends the following:

 Connect the residence associated with WSW-5 to the existing municipal water supply and restrict
the WSW-5 to irrigation use;
 Perform an air-sparge enhanced mobile multi-phase extraction (MMPE) event, utilizing MW-1R and
MW-4 as extraction points, in order to reduce the dissolved concentrations at the site.
 30-days following the MMPE event, a groundwater monitoring event should be performed to
evaluate the effectiveness of the MMPE event.
