SECTION B. EXECUTIVE SUMMARY
1. Summary of Activities Associated with Current TA
WithersRavenel, Inc. (WR) conducted groundwater sampling at the Former American Grocery site located at 41 Upper Shut-In Road in Hot Springs, Madison County, North Carolina in association with task authorization (TA) TA-01 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 monitoring wells MW-1 and MW-2 and purging and sampling of WSW-1 and WSW-2.
2. Soil, Groundwater and LNAPL Assessment Information Soils No soil samples were collected by WR in association with this task authorization. On January 22,
2022, one soil sample was collected at the proposed monitoring well locations for MW-1 and MW-2. The soil samples (SB-1 and SB-2) were collected at depths of 2.5 to 5.0 feet below ground surface (bgs). The SB-1 samples were submitted to a certified laboratory for the analysis of the Risk-Based Rule Parameters: Environmental Protection Agency (EPA) Method 8260 and Massachusetts Department of Environmental Protection (MADEP) Method for volatile petroleum
hydrocarbons (VPH). The SB-2 samples were submitted for laboratory analysis of EPA Method 8260, EPA Method 8270, MADEP VPH and MADEP Method for extractable petroleum hydrocarbons (EPH). Soil samples from boring SB-2 contained 1-methylnaphthalene at a concentration in excess of the Soil-to-Water Maximum Soil Contaminant Concentrations (MSCCs). No compounds were detected above residential MSCCs in soil samples collected from SB-1 or SB-
2. Groundwater WR collected groundwater samples from monitoring wells MW-1 and MW-2 and water supply wells WSW-1 and WSW-2 on October 17, 2023. The groundwater samples were submitted for
laboratory analysis of volatile organic compounds (VOCs) by SM6200B. A field blank was also submitted for analysis of VOCs by SM6200B.
• Laboratory analytical results indicated that no petroleum compounds analyzed exceeded
the Gross Contaminant Level (GCL).
• Laboratory analytical results indicated that benzene and naphthalene exceeded the 15A
NCAC 2L Groundwater Quality Standards (2L Standards) in monitoring wells MW-1 and
MW-2.
• Laboratory analytical results indicated that naphthalene exceeded the 2L Standards in inactive water supply well WSW-1.

• Laboratory analytical results indicated that isopropyl ether (IPE) and methyl-tert-butyl ether (MTBE) were detected in water supply well WSW-2 at concentrations above the
laboratory method detection limits (MDLs) but below the 2L Standards.

• Analytical data for the field blank did not report any compounds above the method
detection limits.
Light Non-Aqueous Phase Liquid Light non-aqueous phase liquid (LNAPL) was not measured in monitoring well MW-1 or MW-2 in October 2023.

3. Receptor Information WR performed a receptor survey in 2022. A total of twenty-eight (28) water supply wells were identified within 1,500-feet (ft) of the subject property. Municipal water is not available to the site
or surrounding area. Shut-In Creek is located approximately 250 feet west of the source area.
4. Remediation Activities Based on WR’s review of historical files available for the site, the following remedial activities have
been completed at the location:

• September 2010 – The underground storage tank (UST) system including two 1,000-gallon USTs, one 6,000-gallon UST, one 550-gallon diesel UST, and one 550-gallon UST of
unknown contents were removed on September 28, 2010. Based on information obtained
from the Initial Abatement Action Report and Underground Storage Tank Closure Report by Mountain Environmental Group, soil was not removed for off-site disposal from the UST excavations. Based on currently available information, no additional remedial actions have been performed at
the site. 5. Recommendations
Based on the results of assessment and monitoring activities conducted at the site in association
with this TA, WR recommends the following:
• Sample monitoring wells, onsite water supply well WSW-1, and off-site water supply well WSW-2 on a semi-annual basis.

SECTION C. SITE HISTORY AND CHARACTERIZATION
The following information summarizes the site history and assessment.
1. UST Information
The site is located at 41 Upper Shut-In Road in a residential/agricultural district in Hot Springs, Madison County, NC (Figure 1). The site is currently an unoccupied commercial building. Two 1,000-gallon USTs, one 6,000-gallon UST, one 550-gallon diesel UST, and one 550-gallon UST of

unknown contents were removed in September 2010. Soil samples obtained from the site in association with UST closure indicated impacts by TPH at levels exceeding NC action levels in the areas of the diesel product line, the diesel dispenser, the 6,000-gallon UST tank pit, and gasoline dispenser #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:

• September 2010 – The UST system including two 1,000-gallon USTs, one 6,000-gallon UST, one 550-gallon diesel UST, and one 550-gallon UST of unknown contents were removed on
September 28, 2010. Based on information obtained from the Initial Abatement Action Report
and Underground Storage Tank Closure Report by Mountain Environmental Group, soil was not removed for off-site disposal from the UST excavations. Soil sampling conducted by Mountain Environmental Group indicated TPH-DRO was detected above the Action Levels in one diesel product line and one diesel dispenser sample. TPH-GRO concentrations were
detected above the Action Levels in one sidewall sample collected from the 6,000-gallon UST
tank pit, gasoline dispenser #2, and one diesel dispenser sample. 3. Brief Description of Site Characteristics

The subject property is located at 41 Upper Shut-In Road (Madison County Parcel I.D. No. 8850364596) in a residential/agricultural district in Hot Springs, Madison County, NC (Figure 2). 4. Information on Receptors/Potential Receptors

A receptor survey was conducted by WR in 2022. A total of twenty-eight (28) water supply wells were identified within 1,500-feet (ft) of the subject property.
• Seven water supply wells are located within 500-feet of the subject property, eight water
supply wells are located between 500 to 1,000 feet of the subject property, and 13 water
supply wells are located between 1,000 and 1,500 feet of the subject property. One water supply well is located on the subject property. Water supply well WSW-1 is inactive and power to the well is turned off.
• WR inquired with the Hot Springs Water Department via telephone to obtain information
regarding the connection status of the properties within 1,500 ft of the site. Municipal water is not available to the site or surrounding area. According to the Hot Springs Water Department, the municipal water line ends approximately 1.5 miles to the east along NW US 25-70 Highway, and the residential properties within 1,500 ft of the subject property are connected to water supply wells and most properties utilize septic systems.
• Although subsurface utilities were identified in the site vicinity, the depth to water at the site is approximately 12 feet below ground surface. Therefore, these utilities are not expected to be conduits for contamination.
• The subject property is not located within a designated wellhead protection area.
• Shut-In Creek is located approximately 250 feet west of the source area.

5. Regional and Site Geology and Hydrology According to the 1985 USGS Geologic Map of North Carolina, the site is underlain by Blue Ridge
Belt sedimentary and metamorphic rock of Paleozoic-Cambrian age. It is described as shale and
siltstone, variegated red to brown, interbedded fine-grained sandstone and shaly dolomite.

Soil encountered at the site during the installation of monitoring wells MW-1 and MW-2 primarily
consisted of minimal amounts of clayey silt between cobbles to the termination of the borings at
a depth of 23 and 24 ft-bgs.

SECTION D. GROUNDWATER SAMPLING – OCTOBER 2023
On October 17, 2023, WR performed groundwater sampling activities at the facility in association with TA-01 under NCDEQ Contract # N70522-C. The scope of work for this project included the gauging, purging, and sampling of monitoring wells MW-1 and MW-2 and the sampling of water supply wells WSW-1 and WSW-2.
The following paragraphs describe the sampling activities and associated laboratory analytical results. Groundwater Sampling Activities Prior to the purging and sampling of the monitoring wells on October 17, 2023, WR personnel
opened and gauged the wells with a decontaminated electronic water level indicator to determine the depth to groundwater. LNAPL was not measured in the monitoring wells. The depth to groundwater measured in monitoring wells MW-1 and MW-2 were 17.22 and 17.29 feet below the top of casing. Based on the topography of the site, groundwater flow direction
appears to be to the northwest. Monitoring well construction and liquid level data is included in Table B-7. 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 and MW-2 were submitted to Waypoint Analytical, Inc. (Waypoint) for testing by SM 6200B. Laboratory Results Analytical results for the groundwater samples collected on October 17, 2023 revealed the
following:
• There were no concentrations above the GCLs in monitoring wells MW-1 and MW-2.
• MW-1: Benzene and naphthalene were reported at concentrations that exceeded the 2L Standards. N-butylbenzene, sec-butylbenzene, ethylbenzene, isopropyl benzene, 4-isopropyltoluene, n-propylbenzene, and 1,2,4-trimethylbenzene were detected above the laboratory method detection limits (MDLs) but below 2L Standards.

Former American Grocery – NCDEQ Inc. #28883 WR Project # 23-0307-BQ Groundwater Monitoring Report November 2023 7
• MW-2: Benzene and naphthalene were reported at concentrations that exceeded the 2L Standards. Sec-butylbenzene, ethylbenzene, isopropyl benzene, and n-propylbenzene
were detected above the laboratory MDLs but below 2L Standards.
The following table compares Total VOCs results from October 2023 to concentrations reported in August 2022.
Well ID Total VOCs August 2022 (µg/L)
Total VOCs October 2023 (µg/L)
Percent Reduction / Increase (+/- %)
MW-1 400.7 289.5 -27.8%
MW-2 1,304.5 24.1 -98.2%
These results are shown on Figure 4 and included in Table B-4. Copies of the laboratory analytical report and chain-of-custody (CoC) are included in Appendix B. Water Supply Well Sampling
A grab sample was collected from inactive water supply well WSW-1. Prior to sampling water
supply well WSW-2, the well pump was activated by turning on an exterior spigot at the property.
The spigot was allowed to flow freely for a minimum of 10 minutes before samples were collected
directly into laboratory-prepared sample containers holding appropriate preservative(s) as
required. The containers were labeled with appropriate information and the supply well samples
were transported in an ice-chilled cooler under proper CoC to Waypoint for analysis of VOCs by
SM6200B.
Water Supply Well Laboratory Results
Analytical results for the samples collected from water supply wells WSW-1 and WSW-2 revealed
the following:
• There were no concentrations above the GCLs in water supply wells WSW-1 and WSW-2.
• WSW-1: Naphthalene was reported at a concentration that exceeded the 2L Standard. No other petroleum compounds were detected above the laboratory MDLs.
• WSW-2: IPE and MTBE were detected above the laboratory MDLs but below 2L
Standards.
• Maximum Contaminant Levels (MCLs) have not been established for naphthalene, IPE, or MTBE in drinking water.

No targeted compounds were present at concentrations that exceeded the laboratory MDLs in the field blank. Copies of the laboratory analytical report and CoC are included in Appendix B.

SECTION E. CONCLUSIONS AND RECOMMENDATIONS This report documents the results of field activities conducted at the site for TA-01, which included purging and sampling of monitoring wells MW-1 and MW-2. Conclusions based on observations,
analytical data and historical information include the following:
• The site is currently an unoccupied commercial building.
• Benzene and naphthalene were reported in samples collected from MW-1 and MW-2 at concentrations that exceeded the 2L Standard.
• Between August 2022 and October 2023, total VOCs have decreased in MW-1 by 27.8% and in MW-2 by 98.2%.
• Naphthalene was detected at a concentration above the 2L Standard in the onsite inactive water supply well WSW-1.
• IPE and MTBE were detected at concentrations below the 2L Standards in water supply well
WSW-2.
• Contaminated soil remains in the former tank basin and dispenser island areas above action levels and 1-methylnaphthalene remains above the soil-to-water MSCCs in the area of the
former diesel pump. Due to the proximity of the contaminated soil to the building, removal of
the contaminated soil could potentially compromise the building foundation.
• Cobbles were encountered at approximately 2-3 feet bgs, and due to the geology at the site, a remedial product could not be injected using a geoprobe. Injection wells installed via sonic
drilling would be required for the injection of a remedial product.
Based on the results of the assessment activities conducted at the site in association with this TA, WR recommends the following:
• Sample monitoring wells, inactive onsite water supply well WSW-1, and off-site water supply well WSW-2 on a semi-annual basis to determine if natural attenuation is effective at reducing contaminant concentrations.

Dear Flora D'Souza:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 10/24/2023 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,

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 a contaminant-free tap water solution. Use a brush to remove particulate matter and surface films as necessary,
• 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 of equipment 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.
