SECTION B. EXECUTIVE SUMMARY
1. Summary of Activities Associated with Current TA
WithersRavenel, Inc. (WR) purged and sampled monitoring wells located at the site in association with TA-01 and a change order under North Carolina Department of Environmental Quality (NCDEQ) Contract #N70522-C. The scope of work for this project included the gauging, purging, and sampling of existing monitoring wells MW-1, MW-3, MW-4, and MW-5, and supply well
WSW-1.
2. Soil, Groundwater and LNAPL Assessment Information Soils No soil samples were obtained by WR in association with the current task authorization.
According to historical reports, soil samples were collected from boreholes during the installation of groundwater monitoring wells MW-2, MW-3, and MW-4. The soil samples were submitted to a laboratory for analysis of volatile organic compounds (VOCs) by EPA Method 8260 and testing of aliphatic and aromatic hydrocarbons by the Massachusetts Department Environmental Protection (MADEP) volatile petroleum hydrocarbons (VPH) method. Analytical results for the soil
samples did not show targeted compounds or hydrocarbon chains at concentrations exceeding their respective Soil-to-Water Maximum Soil Contaminant Concentrations (MSCCs). Groundwater WR collected groundwater samples from site monitoring wells MW-1, MW-3, MW-4, and WSW-
1 on June 29, 2023. Based on the detection of several petroleum compounds in WSW-1, NCDEQ requested for WSW-1 to be resampled and monitoring well MW-5, which is located between MW-1 and WSW-1, to be sampled. Monitoring well MW-5 and supply well WSW-1 were sampled on July 14, 2023. The collected groundwater samples were submitted for laboratory analysis of VOCs by SM6200B.
No targeted compounds were reported at concentrations that exceeded their Gross Contamination Level (GCL). One or more targeted compounds were identified at concentrations that exceeded the 15A NCAC 2L Groundwater Quality Standards (2L Standards) in monitoring wells MW-1, MW-3, MW-4, and WSW-1 during the June 29, 2023 sampling event.
No targeted compounds were reported in monitoring well MW-5 or water supply well WSW-1 in samples collected on July 14, 2023 at concentrations that exceeded the laboratory method detection limit (MDL).
No targeted compounds have been detected in water supply well WSW-1 during sampling events prior to June 29, 2023 and during the July 14, 2023 sampling event, therefore, it appears that there was an error associated with the sample results for WSW-1 from the June 29, 2023 sampling event.

Light Non-Aqueous Phase Liquid (LNAPL) No LNAPL was measured in the gauged monitoring wells in June or July 2023, WR is not aware of the historical presence of LNAPL in any of the sites monitoring wells.
3. Receptor Information WR completed a receptor survey update in March 2016, which identified 24 water supply wells that are used for potable water located within 1,000-feet (ft) of the site. According to Sean McGuire with NCDEQ, there are no wellhead protection areas within 1,000-ft of the subject
property. However, there are two Public Water Supply (PWS) regulated wells; PWS System ID 1011018, Hotdog King; State ID SO1; and PWS System ID 1011017, BJ’s Gas and Food; State ID W02. Both wells are Transient-Non-Community Water Systems defined as serving 25+ people at least 60 days per year.
According to Ms. Florie Presnell, Customer Service Division Manager Water Resources
Department with the City of Asheville, the subject property is outside the City of Asheville’s Water System and the area is served by private water supply wells. The closest water line is located approximately 2,000 feet east of the subject property near the intersection of Smokey Park Highway and N. Morgan Branch Road. No surface water bodies were identified within 1,000 ft of the site in the completion of the receptor survey.
The closest active water supply well, WSW-1, also identified as BJ’s Gas and Food; PWS System ID 1011017, is located within 50 ft of the UST basin.
Laboratory results for samples obtained from supply wells WSW-1, WSW-3, WSW-9, WSW-10, WSW-11, and WSW-14 in January 2021 did not indicate the presence of targeted compounds at concentrations above the method detection limits for SM6200B.
4. Remediation Activities During the UST closure activities completed during July 1995, 250 cubic yards of impacted soil was removed and disposed of offsite. During the March 2018 sampling event, WR personnel
installed Provectus ORS socks in monitoring wells MW-1, MW-3, and MW-4. An 8-hour aggressive fluid vapor recovery (AFVR) event was conducted on May 19, 2022. A total of 300 gallons of water was recovered from monitoring well MW-1 during the AFVR. WR is not aware of any additional remediation activities.
5. Recommendations Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following:

• Continued semi-annual groundwater monitoring of monitoring wells MW-1, MW-3, and MW-4 and water supply well WSW-1.
• Conduct an 8-hour AFVR in monitoring well MW-1.

SECTION C. SITE HISTORY AND CHARACTERIZATION WR has completed a groundwater sampling event at the referenced site in association with TA-01 at the facility. The following information summarizes the site history and characterization.
1. UST Information The site currently sells gasoline and diesel to the general public under Facility ID No. 00-0-000007090. According to the NCDEQ UST database, the subject property operates an UST
system consisting of one 12,000-gallon (gal) gasoline UST, one 8,000-gal gasoline UST, one 4,000-gal diesel UST, and one 2,000-gal diesel UST. According to historical reports, the current UST system replaced older systems. The older systems included two 4,000-gal gasoline USTs, four 3,000-gal gasoline USTs, and one 3,000-gal diesel UST.
These seven USTs were reportedly installed in 1976 and removed in July 1995. Table B-1 includes information regarding the USTs reportedly formerly located on the property, as well as those currently in-place. A General Location Map is included as Figure 1 and a Site Map illustrating current site conditions is included as Figure 2.
2. Description of Release/General Assessment History The following summary of the assessment history is based on WR’s review of historical files for the subject incident:
• According to the May 27, 2008 LSA Phase II Report completed by Singleton & Jordon Environmental Services, PLLC:
o Seven former USTs were removed during the week of July 10, 1995.

• In July 2022, WR completed a groundwater monitoring event at the site which included
sampling monitoring wells MW-1 and MW-4. Analytical data for the groundwater samples collected from monitoring wells MW-1 and MW-4 indicated the presence of several petroleum compounds above their respective 2L Standards.
3. Brief Description of Site Characteristics
According to the Buncombe County GIS website the ±0.72-acre parcel is identified by parcel pin number 8687-83-1530-0000 and is currently owned by Vijya Laxmi, LLC, in Asheville, NC. The GIS website shows that the subject property was bought by the current owner in May 2011. The
facility currently operates as BJ’s Gas and Food and sells retail gasoline and diesel under facility ID
No. 00-0-000007090. 4. Information on Receptors/Potential Receptors
WR completed a receptor survey update in March 2016, which identified 24 water supply wells
that are used for potable water located within 1,000-feet (ft) of the site. According to Sean McGuire with NCDEQ, there are no wellhead protection areas within 1,000-ft of the subject property. However, there are two Public Water Supply (PWS) regulated wells; PWS System ID 1011018, Hotdog King; State ID SO1; and PWS System ID 1011017, BJ’s Gas and Food; State ID
W02. Both wells are Transient-Non-Community Water Systems defined as serving 25+ people at
least 60 days per year.
According to Ms. Florie Presnell, Customer Service Division Manager Water Resources Department with the City of Asheville, the subject property is outside the City of Asheville’s Water System and the area is served by private water supply wells. The closest water line is located
approximately 2,000-feet east of the subject property near the intersection of Smokey Park
Highway and N. Morgan Branch Road. No surface water bodies were identified within 1,000 ft of the site in the completion of the receptor survey.
The closest active water supply well, WSW-1, also identified as BJ’s Gas and Food; PWS System ID 1011017, is located within 50 ft of the UST basin.
Public and private water supply well information is provided as Table B-5. These receptors are
illustrated on Figure 5. 5. Regional and Site Geology and Hydrology
The site is located in the Blue Ridge Mountains Physiographic Province of North Carolina. Based
on interpretation made from the Geologic Map of North Carolina (1985), the area is underlain by sedimentary and metamorphosed rocks of the Blue Ridge Belt consisting of Muscovite-Biotite gneiss, locally sulfidic, Interlayered & Gradational with mica schists, minor amphibolite, and hornblende gneiss.

Soils in this region are typically composed of residual weathering products of the underlying parent rocks. A transitional zone exists between the un-weathered bedrock and the overlying soil. This
WithersRavenel

regolith is primarily saprolite, a clay-rich residuum derived from the in-situ weathering of the underlying bedrock. The thickness of a saprolite unit can often vary considerably within a given locale. Well construction records for the groundwater monitoring wells installed on the property state that area soils consist of brown and gray silts and clays to approximately 55 ft below ground
surface. The Enka 7.5-minute topographic map (Figure 1) indicates that the subject property is approximately 2,260 ft above mean sea level. Slight topographic relief is present towards the east. SECTION D. GROUNDWATER SAMPLING – JUNE/JULY 2023
WR completed assessment activities which included gauging, purging and sampling monitoring wells MW-1, MW-3, MW-4, and MW-5, and supply well WSW-1.
Groundwater Elevations Prior to the purging and sampling of monitoring wells as described below, WR personnel gauged
each well targeted for sampling with an electronic water level indicator to determine the depth to groundwater at each well location. LNAPL was not measured in any of the monitoring wells gauged in association with sampling activities. The depth to groundwater measurements in the monitoring wells ranged from 35.20 ft. below the
top of casing (ft-BTOC) in monitoring well MW-3 to 37.80 ft-BTOC in monitoring well MW-1. Based upon data for groundwater elevations obtained in June 2023, general groundwater flow appears to trend to the east-northeast. This direction of groundwater flow is generally consistent with past assertions. Groundwater elevation and well construction information for the site wells is included in Table B-7, while a hydraulic gradient map is included as Figure 3.
Groundwater Sampling WR collected groundwater samples from site monitoring wells MW-1, MW-3, and MW-4 on June 29, 2023 and from MW-5 on July 14, 2023. Following gauging, the monitoring wells were purged
and sampled with disposable polyethylene bailers. The groundwater samples from the wells were decanted into pre-preserved laboratory- provided sample containers. The sample collected from monitoring wells MW-1, MW-3, MW-4, MW-5, and a field blank were submitted to Waypoint Analytical, Inc. (Waypoint) for testing by SM 6200B.

Laboratory Analytical Results Laboratory analytical results indicated that no targeted petroleum compounds exceeded the GCLs in monitoring wells MW-1, MW-3, MW-4, and MW-5. One or more targeted compounds were identified at concentrations that exceeded the 2L Standard in monitoring wells MW-1, MW-3, and
MW-4. The following table compares Total VOCs results from June 2023 to concentrations reported in April 2008.

Reductions in Total VOCs were observed in MW-1, MW-3, and MW-4 when compared to VOC data from April 2008. Water Supply Well Sampling
WR collected samples from WSW-1 on June 29, 2023 and July 14, 2023. The well was purged by
allowing the well pump to run continuously for a minimum of ten minutes prior to collecting the samples. Supply well samples were submitted to Waypoint for analysis by SM6200B. Laboratory Results
Naphthalene was detected above the 2L Standard in WSW-1 during the June 29, 2023 sampling
event. Since no targeted petroleum compounds had been previously detected in WSW-1, the water supply well was resampled on July 14, 2023. Analytical results for the sample collected from WSW-1 on July 14, 2023 did not indicate targeted petroleum compounds at concentrations exceeding the laboratory MDLs.

No targeted petroleum compounds have been detected in water supply well WSW-1 during sampling events prior to June 29, 2023 and during the July 14, 2023 sampling event, therefore, it appears that there was an error associated with the sample results for WSW-1 from the June 29, 2023 sampling event.

These results are shown on Figure 4 and included in Table B-4. Copies of the laboratory analytical report and chain-of-custody are included in Appendix A. Copies of field notes and site photographs are included in Appendix B. WR’s generalized standard operating procedures are provided in Appendix C. A receptor map is included as Figure 5.
SECTION E. CONCLUSIONS AND RECOMMENDATIONS This report documents the results of field activities conducted at the site in association with TA-
01 which included the gauging, purging, and sampling of monitoring wells MW-1, MW-3, MW-4,
and MW-5, water supply well WSW-1, and a field blank. Conclusions based on observations, analytical data and research relating to the release at the site combined with historical information include the following:
• Municipal water is not available to the subject property or surrounding area. The site and all surrounding properties are provided potable water through private water supply wells.
• No LNAPL was observed during June/July 2023 sampling events.
• No petroleum compounds were reported at concentrations that exceed their respective GCLs.

• Exceedances to the 2L Standard were reported in monitoring wells MW-1, MW-3, and MW-4, and water supply well WSW-1 in the samples collected on June 29, 2023.
• No compounds were reported at concentrations above the laboratory MDLs for monitoring well MW-5 or water supply well WSW-1 in the samples collected on July 14, 2023.
• No targeted compounds have been detected in water supply well WSW-1 during sampling
events prior to June 29, 2023 and during the July 14, 2023 sampling event, therefore, it
appears that there was an error associated with the sample results for WSW-1 from the June 29, 2023 sampling event.
• Reductions in Total VOCs were observed in MW-1, MW-3, and MW-4 when compared to
VOC data from April 2008.
Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following:
• Continued semi-annual groundwater monitoring of monitoring wells MW-1, MW-3, and MW-4 and water supply well WSW-1.
• Conduct an 8-hour AFVR in monitoring well MW-1.

Dear Flora D'Souza:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 7/18/2023 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated.
Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report.
Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Angela D Overcash Senior Project Manager

Soil Sampling, Soil Boring and Monitor Well Installation, Well Development
Soil borings are installed utilizing a stainless-steel hand auger, direct-push hydraulic drill or auger rotary
drill using either a macro core™ sampler, hollow stem augers, or air rotary roller cone bit. Soil borings are
typically sampled at discrete intervals from the bucket of a clean stainless steel hand auger, direct push stainless steel sampler with acetate sleeve, or a split barrel sampler. When appropriate, soil samples may be collected from drill cuttings associated with the boring or well installation.
Monitor wells are constructed within select soil borings of one, two, or four-inch inside diameter PVC
casing and machine slotted screen in accordance with NCAC Title 15A, Subchapter 02C (Well Construction Standards, Criteria and Standards Applicable to Water Supply and Certain Other Wells). Clean-washed “#2 Torpedo Sand” is typically utilized to fill the boring annulus surrounding the well screen, extending to a minimum of 1-foot above the well screen. A minimum 1-foot thick bentonite clay seal is emplaced above the sand pack and hydrated. Neat cement grout is placed in the remaining annulus
space from the upper portion of the bentonite seal to within 1-foot of surface grade. In coastal plain areas where shallow groundwater is encountered, a variance to construction standards may be employed to ensure the upper portion of the well screen intersects the upper aquifer surface. Wellheads may be completed with either concrete-set flush mounted traffic-bearing steel skirted manholes with bolt down covers or steel above-ground “stick-up” well protectors set in a concrete pad. The monitoring wells are
secured with locking caps. Temporary wells or piezometers may be completed with the PVC riser cut at or above grade, and are abandoned within 24-hours of their installation.
Wells may be developed using a bailer, electric submersible pump, pneumatic pump, or peristaltic pump, dependent upon site conditions. When wells are developed by the driller, they may be developed with
any of the methods outlined above, in addition to air or water injection. Soil boring logs and well construction details are typically prepared for presentation in a report appendix. Borings completed in bedrock may be drilled using air rotary, coring, or sonic drilling methods.
Groundwater Depth to Water Measurements
Groundwater level measurements are typically obtained using an electronic water level indicator which registers a tone and/or illuminated light when the probe contacts groundwater. Depth to groundwater measurements are obtained by lowering the probe attached to a cable usually marked in 0.01 foot intervals into the well until the probe of the meter intersects the water surface. The measurement from
the top of the riser pipe or top of casing (TOC) to the water level is recorded to the nearest 0.01 foot. The
electronic water level indicator probe and exposed probe cable is decontaminated between measurement locations.

Free Product Level Measurements Light Non-Aqueous Phase Liquid (LNAPL) or “free product” present on the water table is measured using
an electronic oil/water interface probe. The interface probe has both an audible and illuminating light
that indicate when a liquid level is encountered. The oil/water interface probe registers a solid tone and solidly lit light when LNAPL petroleum product is encountered and a beeping tone flashing light when groundwater is encountered. Depth to LNAPL measurements are obtained by lowering the probe attached to a cable marked in 0.01 foot intervals into the well until the probe of the meter intersects the product or groundwater. The measurements from the top of the riser pipe or TOC to the liquid level are
recorded to the nearest 0.01 foot. The thickness of LNAPL is calculated by subtracting the depth to LNAPL measurement from the depth to groundwater measurement. The electronic interface probe is decontaminated between measurement locations. Soil Sampling and Field Screening
Soil sampling is performed in general accordance with ASTM: 1586-84 where applicable. Sampling procedures are followed to protect the chemical integrity of the soil samples and minimize the potential for cross contamination between sample locations, including discarding of the exterior of the sample which contacts the auger bucket, acetate sleeve, or split barrel sampler, the use of stainless steel sampling
equipment, and the thorough decontamination of sampling apparatus prior to use and between sample locations. Soil samples retained as a part of excavation or other intrusive “digging” activities may be collected from the bucket of excavation equipment or using a hand shovel, if appropriate. Care to collect soil samples
from excavation equipment includes retrieving native soil from material that has not made contact with the excavating equipment. Samples are collected in sealable bags or by directly filling sample containers as described above. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample
integrity and minimize the potential for cross contamination or field personnel exposure to contaminants.
Sampling equipment such as hand auger extensions and buckets, direct push samplers, split spoons or shovels, are decontaminated prior to their use in the collection of samples. Samples are placed within laboratory grade sample containers provided by the laboratory to which the
samples are submitted, labeled, sealed, and placed in an ice filled cooler. An aliquot of the sample is
typically placed in a clean sealable bag and allowed to reach ambient air temperature for future screening of volatile vapor content with a photoionization detector (PID), flame-ionization detector (FID) or other portable screening device.
Screening of samples with a PID, FID or other field screening device is performed in accordance with
device manufacturer specifications for screening, following calibration of the instrument based on manufacturer recommended procedures.

Groundwater Sampling
Groundwater samples are generally collected using one of three standard methods – through the use of a
dedicated, disposable bailer, a peristaltic pump or submersible electric pump.
When sampling with a bailer, a minimum of three well volumes of groundwater are extracted from the well as a means of purging, unless the well is purged to a “dry” state prior to the removal of three volumes of water. Prior to collection of the groundwater sample with the bailer, the water level is allowed to recover to within 80% of the original level measured prior to purging.
When sampling with a peristaltic or submersible electric pump, polyethylene (PE) tubing (or equivalent) is emplaced into the screened section of the monitoring well, and the pump is used to extract water through the tubing. When using the either of these methods, general water quality measurements including but not limited to pH, temperature, dissolved oxygen (DO), oxygen reductive potential (ORP), specific
conductivity and turbidity may be used as methods for determining when an adequate purge of the well has been conducted. When water quality parameters are measured, the resulting data are included in well purge forms or field notes specific to each site and sampling point.
Following the purging of three well volumes of groundwater (in the case of the bailed well) or stability of
monitored measurements (in the case of the peristaltic or submersible electric pump), the groundwater sample(s) are introduced directly into sample containers provided by the laboratory to which samples are ultimately submitted for analysis. Any samples requiring chemical preservation are contained in pre-preserved container(s) provided by the laboratory.
Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination of samples or field personnel exposure to contaminants.
Water Supply Well Sampling
Sampling of water supply wells is accomplished through the collection of a representative sample from an in-line water tap or other point accessible for sampling. Where possible, the sample is collected from a point prior to any filtration or point of entry (POE) system which might be installed on a well. In some cases, samples will be collected from both pre and post-POE locations. Prior to the collection of samples
through an in-place sampling point, the tap or sampling port is cleaned with an Alconox® and deionized
water solution, rinsed with deionized water, and again with an isopropyl alcohol (IPA) rinse.
In the case of active supply wells (e.g., a well with a useable well pump with an active power supply), the well pump is energized and allowed to run for a minimum of ten (10) minutes time, after which a sample is
contained in laboratory grade sample containers as described in the previous section. Water quality
parameters may be (but are not necessarily) measured in association with the well purging.
Supply wells without active power supplies are not generally sampled, as the well seal cannot be compromised by individuals not certified as a well contractor. However, in the case of a well with no
power supply or pump installed, samples could be obtained through the use of a bailer, peristaltic pump or
electric submersible pump.

Decontamination Procedures
Decontamination procedures employed in the performance of field activities will vary dependent upon
the method(s) of sampling performed at any site, but will generally include the following:
•Remove excess soil/sludge from any sampling equipment as needed,•Wash and scrub the equipment with a phosphate-free detergent such as Alconox® or Liquinox® in acontaminant-free tap water solution. Use a brush to remove particulate matter and surface films asnecessary,
•Rinse thoroughly with tap water,•Rinse thoroughly with analyte-free water (deionized water),
Rinse thoroughly with isopropyl alcohol,•Allow the equipment to air dry,
•Prevent inadvertent contamination during storage and transport (accomplished through storage ofequipment in foil or plastic bags/sheeting).
In the case of disposable bailers and tubing utilized for the purging and sampling of wells, these items may be decontaminated prior to their disposal. In general, no decontamination of these items is necessary
prior to their use in sampling.
