2.0 EXECUTIVE SUMMARY

ATC Associates of North Carolina, P.C. (ATC) has completed a Groundwater Monitoring Report
for the Bethlehem Trading Post site. This report documents a groundwater sampling event
conducted in December 2019. These activities were performed based on a November 22, 2019 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).
This work is being performed as part of State Lead Contract #N17004 between NCDEQ and ATC.

Bethlehem Trading Post is located at 102 Haliwa Saponi Trail in Old Bethlehem, Warren County,
North Carolina. The site consists of a one story building with gravel parking on the corner of
Haliwa Saponi Trail and Richardson Road and currently is owned by Joyce Evans Reid. Three
monitoring wells (MW-1, MW-2, and MW-3) are located at the site. Fourteen water supply wells
are located within 1,000 feet of the site.

On December 26, 2019, ATC mobilized to the site to sample monitoring wells MW-1, MW-2,
and MW-3 and water supply wells WSW-102 and WSW-105. Laboratory analytical results of the
sampling event indicate petroleum hydrocarbon compounds at concentrations exceeding North
Carolina Groundwater Quality Standards (2L Standards) in monitoring wells MW-1 and MW-3.
Compounds exceeding 2L Standards include ethylbenzene, xylenes, naphthalene, 1,2,4-
trimethylbenzene, 1,3,5-trimethylbenzene, isopropylbenzene, n-propylbenzene, and 1,2,3-
trichloropropane. Results from WSW-102 indicated the presence of 1,2-dichloroethane above the
laboratory detection limit, but below the 2L Standard. Water supply well WSW-105 did not
contain any compounds above the laboratory detection limits.

A review of concentration trends in monitoring well MW-1 indicate benzene, toluene,
ethylbenzene, and total xylenes exhibit a decreasing trend; however, 1,3,5-trimethylbenzene
exhibits no trend and 1,2,4-trimethylbenzene and naphthalene exhibit an increasing trend.
Remedial efforts (Aggressive Fluid and Vapor Recovery [AFVR] events and Oxygen Release
Compounds [ORC] socks) have not been effective in reducing concentrations of all detected
compounds. If funding is available, ATC recommends additional assessment activities followed

by completion of a Corrective Action Plan. In the interim, ATC recommends semi-annual
sampling of the monitoring wells and active water supply wells onsite and to the east of the site.

3.0 SITE DESCRIPTION

3.1 Site Characterization

Bethlehem Trading Post is located at the southwest corner of the intersection of Haliwa Saponi
Trail and Richardson Road in Old Bethlehem, North Carolina. The site address is 102 Haliwa
Saponi Trail, Old Bethlehem, North Carolina. The surrounding area is primarily a mix of residential
and undeveloped properties. The site formerly contained a retail convenience store with petroleum
sales. In October 1992, two 8,080-gallon gasoline USTs and associated piping were removed from
the site. The former Bethlehem Trading Post site is currently operating as a convenience store.

The site is bounded by North Richardson Road to the north, Haliwa Saponi Trail to the east, and an
undeveloped lot to the west and south. A residence is located on the site property. Residential
properties are located to the north, east, south and west of the property. Fourteen water supply wells
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 pertinent site
features is included as Figure 2. A Potential Receptor Map showing select water supply well
locations is included as Figure 3.

3.2 Site Background

The former Bethlehem Trading Post was a convenience store and retail petroleum facility. Per
the NCDEQ UST database, the UST system was installed at the site in May 1971. On July 26,
1991, the store was reported to the Raleigh Regional Office (RRO) for petroleum odors detected
in the onsite supply water. The USTs were not in use at that time. On August 1, 1991, the RRO
collected three water samples for laboratory analysis and a Pollution Incident/UST Leak
Reporting Form was filed on July 31, 1991.

A Notice of Violation was issued by the RRO to Joyce Richardson, the property owner, on
January 18, 1992, and the site was recommended for inclusion into the Leaking Underground
Storage Tank (LUST) Federal Trust Fund (FTF) on February 21, 1992. On October 1 and 2,
1992, Geophex, LTD. (Geophex) removed two 8,080-gallon USTs and their associated piping.
One UST contained approximately 120 gallons of residual fluids and the second UST contained
approximately 45 gallons of residual fluids. Approximately 20 cubic yards of contaminated soil
was removed and stockpiled. Note that a 200-gallon kerosene AST present at the time of the
UST closure, was not removed and is still present at the site. Five soil samples collected and
analyzed for gasoline-range total petroleum hydrocarbons (TPH GRO) indicated concentrations
ranging from 2.6 milligrams per kilogram (mg/kg) to 730 mg/kg. The stockpiled soil was land-
farmed on the property on November 11, 1992. A Report of Tank Closure was submitted on
December 29, 1992.

On August 24, 2000, Geophex conducted a geophysical survey to identify depth to bedrock
surface for the purposes of installing a new water supply well (WSW-102) for the Bethlehem
Trading Post. In January 2001, Groundwater Management Associates, Inc. (GMA), verified the
connection of the new water supply well and confirmed the old well had been disconnected.
WSW-102 was tested for petroleum-related constituents and none were detected. This well was
resampled on January 11, 2006, and no petroleum-related constituents were reported in the
sample. Historical water supply well sampling results are summarized in Table 2.

On November 12, 2007, GMA completed a receptor survey within 1,000 feet of the site for
potential receptors. One active potable well and one inactive well are located on the site
property. GMA installed one permanent groundwater monitoring well (MW-1) on December 5,
2007. One groundwater and three soil samples were collected and submitted for analysis. The
groundwater sample indicated multiple petroleum related constituents above 2L Standard. No
petroleum compounds were detected above Soil-to-Groundwater Maximum Contaminant
Concentrations (MSCCs) in the soil samples. A Phase I Limited Site Assessment was submitted
on March 26, 2008.

On September 25, 2008, a LUST Action Plan was prepared by the NCDEQ as required by
Region 4 of the Environmental Protection Agency (EPA). The LUST Action Plan documented
the discovery of the release, potable well sampling events, the installation of a point-of-entry
(POE) system on the store well, the installation of the replacement store well (WSW-102) by the
Federal Trust Fund, and a March 2008 Phase I LSA. Based on the findings of the LUST Action
Plan, the NCDEQ determined that periodic sampling of the closest, at-risk water supply wells
was required and provision of alternative water, if necessary. Also, a short-term groundwater
remediation event on the store property was recommended, as funds were available.

On July 22, 2015, ATC submitted a Federal/State Lead Letter Report documenting an August
2014 groundwater and water supply well sampling event. Based on the report, numerous
compounds were detected above the 2L Standards in monitoring well MW-1. Water supply well
analytical results for sampled wells WSW-101, WSW-102, and WSW-105 did not indicate
compounds above laboratory detection limits. ATC recommended performing an AFVR event
on monitoring well MW-1, installation of ORC socks in the monitoring well to aid in natural
attenuation at the site, and semi-annual sampling of water supply wells in the site vicinity.

On December 29, 2015, ATC submitted a Federal/State Lead Letter Report documenting the
results of an AFVR event, installation of ORC socks in MW-1, and groundwater and water
supply sampling event. The report indicated numerous constituent concentrations had been
reduced. ATC recommended performing a receptor survey and a semi-annual sampling event.

ATC conducted a groundwater and water supply well sampling event on May 20, 2016, which
was documented in a Federal/State Lead Letter Report submitted June 16, 2016. The laboratory
results indicated constituent concentrations continued to decrease; however, ATC determined
AFVR events were more effective in reducing compound concentrations in the subsurface than
ORC socks based on the concentration trends. Therefore, ATC recommended two quarterly
AFVR events followed by a sampling event.

ATC supervised an AFVR event on July 11, 2016. This event recovered 255 gallons of impacted
groundwater and 0.37 gallons of gasoline removed as vapor. The results of the July 2016 AFVR
event were documented in a Free Product Recovery Report dated August 27, 2016.

A second AFVR event was performed on October 28, 2016 and a total of 235 gallons of
impacted groundwater was removed. On November 28, 2016, a groundwater sampling event
was performed. The results of the sampling event indicated that MW-1 exceeded the 2L
Standards for numerous constituents. Water supply well laboratory results indicated acetone
above the detection limit but below the reporting limit for WSW-101, WSW-102 and WSW-105.
Acetone is not a petroleum-related compound and is typically a laboratory contaminant. In
addition, WSW-105 contained chloromethane at a concentration above the reporting limit but
below the 2L Standard. The results of the AFVR and the groundwater sampling event were
documented in a Groundwater Monitoring Report, prepared by ATC, dated January 27, 2017.
ATC recommended an additional AFVR event to decrease constituents below the 2L Standard in
MW-1 as well as continued monitoring events on MW-1 and select potable water supply wells.

On August 15, 2018, ATC submitted a Groundwater Monitoring Report documenting the results
of a groundwater and water supply sampling event. The report identified numerous constituent
concentrations had been reduced; however, naphthalene, 1,2,4-trimethylbenzene, 1,3,5-
trimethylbenzene, isopropylbenzene, and n-propylbenzene exhibited their highest observed
concentrations. Samples were collected from potable water supply wells WSW-102 and WSW-
105. Water supply well laboratory results did not indicate the presence of compounds above the
laboratory detection limits. ATC recommended performing additional assessment work to further
understand subsurface impacts.

On April 16, 2019, ATC submitted an Updated Receptor Survey Letter Report. The receptor
survey identified twenty-five water supply wells within 1,500 feet of the site, fourteen of which
are located within 1,000 feet of the site. Of the fourteen wells, five are inactive, five are used for
drinking purposes, two are used for non-potable purposes, and two have unknown statuses.

On August 5, 2019, ATC submitted a Groundwater Monitoring Report documenting the
installation of monitoring wells MW-2 and MW-3 and the results of a groundwater sampling
event. Results from MW-1 and MW-3 indicated concentrations of ethylbenzene, xylenes,
naphthalene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, isopropylbenzene, n-propylbenzene,
and methylene chloride at concentrations exceeding the 2L Standard. ATC recommended semi-
annual sampling of the monitoring wells and active water supply wells onsite and to the east of
the site.

4.0 GROUNDWATER CHARACTERIZATION

4.1 Groundwater Levels

Groundwater level measurements were collected from monitoring wells MW-1 through MW-3 on
December 26, 2019. Depth to groundwater ranged from 14.23 feet below ground surface (bgs) in
MW-1 to 15.38 feet bgs in MW-2. Light non-aqueous phase liquid (LNAPL) was not observed.
Monitoring well construction details and current and historical groundwater elevation data are
summarized in Table 3. Groundwater flow direction at the site was determined to be to the east. A
groundwater elevation contour map is included as Figure 4. Field notes are presented in Appendix
A.

4.2 Groundwater Quality

On December 26, 2019, groundwater samples were collected from monitoring wells MW-1 through
MW-3. The 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. The groundwater samples were analyzed for volatile organic compounds (VOCs) by
EPA Method 6200B.

Results indicate petroleum hydrocarbon compounds at concentrations exceeding 2L Standards in
monitoring wells MW-1 and MW-3. Compounds exceeding 2L Standards include ethylbenzene,
xylenes, naphthalene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, isopropylbenzene, n-
propylbenzene, and 1,2,3-trichloropropane. No compounds exceeded Gross Contaminant Levels

(GCLs). Current groundwater analytical data are summarized in Table 4 and historical
groundwater analytical data is summarized in Table 5. Natural attenuation parameters were
collected during the sampling event and are summarized in Table 6. A dissolved naphthalene
isoconcentration contour map is included as Figure 5. A figure depicting additional
contaminants of concern in groundwater is included as Figure 6. The laboratory analytical
report and chain-of-custody forms are included in Appendix B.

ATC utilized a GSI Mann-Kendall Toolkit to determine concentration trends in MW-1. Based
on the toolkit, benzene, toluene, ethylbenzene, and total xylenes are “decreasing”. The toolkit
also indicates 1,3,5-trimethylbenzene have “no trend” and 1,2,4-trimethylbenzene and
naphthalene are “probably increasing”. Four sampling events are necessary to establish a trend
and monitoring wells MW-2 and MW-3 have only been sampled twice. As a result, a trend
analysis has not been prepared for these two monitoring wells. The GSI Mann-Kendall Toolkit is
included as 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 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
report 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.

4.3 Water Supply Well Sampling

On December 26, 2019, water supply well samples were collected from WSW-102 and WSW-105.
The samples were collected in laboratory-approved containers, packed in ice and delivered under
chain-of-custody protocol to SGS for analyses for VOCs by EPA Method 6200B. Results from
WSW-102 indicated the presence of 1,2-dichloroethane above the laboratory detection limit, but

below the 2L Standard. 1,2-Dichloroethane has not previously been detected in WSW-102.
Water supply well WSW-105 did not contain any compounds above the laboratory detection
limits. Water supply well analytical data are summarized in Table 2. The QA and QC measures
and conditions applicable to the monitoring well sampling also apply to the water supply well
sampling. The laboratory analytical report and chain-of-custody forms are included in Appendix
B.

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 December 2019 groundwater monitoring event at Bethlehem
Trading Post located at 102 Haliwa Saponi Trail in Old Bethlehem, Warren County, North
Carolina. Results from the groundwater monitoring event indicate petroleum constituents above
the 2L Standards in monitoring wells MW-1 and MW-3. Results from WSW-102 indicated the
presence of 1,2-dichloroethane above the laboratory detection limit, but below the 2L Standard.
Water supply well WSW-105 did not contain any compounds above the laboratory detection
limits.

A review of concentration trends in monitoring well MW-1 indicate benzene, toluene,
ethylbenzene, and total xylenes exhibit a decreasing trend; however, 1,3,5-trimethylbenzene
exhibits no trend and 1,2,4-trimethylbenzene and naphthalene exhibit an increasing trend.
Remedial efforts (AFVR events and ORC socks) have not been effective in reducing
concentrations of all detected compounds. If funding is available, ATC recommends additional
assessment activities followed by completion of a Corrective Action Plan. In the interim, ATC
recommends semi-annual sampling of the monitoring wells and active water supply wells onsite
and to the east of the site.

Notes:
1.At least four independent sampling events per well are required for calculating the trend. Methodology is valid for 4 to 40 samples.
2.Confidence in Trend = Confidence (in percent) that constituent concentration is increasing (S>0) or decreasing (S<0): >95% = Increasing or Decreasing;
≥ 90% = Probably Increasing or Probably Decreasing; < 90% and S>0 = No Trend; < 90%, S≤0, and COV ≥ 1 = No Trend; < 90% and COV < 1 = Stable.
3.Methodology based on "MAROS: A Decision Support System for Optimizing Monitoring Plans", J.J. Aziz, M. Ling, H.S. Rifai, C.J. Newell, and J.R. Gonzales,
