SECTION B. EXECUTIVE SUMMARY
1. Summary of Activities Associated with Current TA
WithersRavenel, Inc. (WR) conducted a groundwater sampling event at the L.C. Hudspeth Store site in Collettsville, Caldwell 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 existing monitoring wells MW-1, MW-2, MW-3, MW-4R, MW-5, and MW-6. A field blank was also analyzed as a part of this TA. Water supply well WSW-3 was not sampled due to power being
turned off to the well during renovations at the residence. 2. Soil, Groundwater and LNAPL Assessment Information
Soils
No soil samples were collected by WR in association with this task authorization. During April 1995, one 550-gallon diesel underground storage tank (UST), one 550-gallon kerosene UST, and one 1,000-gallon gasoline UST were removed, and one 2,000-gallon gasoline UST was closed in place. Closure samples indicated that total petroleum hydrocarbons (TPH) gasoline range organics (GRO) and diesel range organics (DRO) were above the regulatory action levels near the 550-gallon
diesel UST, the 1,000-gallon gasoline UST and the dispenser island. WR is not aware of the presence of any risk-based soil data from the extents of the UST Closure excavations. Approximately 12 cubic yards of petroleum impacted soil were removed during the UST closure activities.
Terracon Consultants, Inc. (Terracon) oversaw the installation of three soil borings (SS-1 through SS-3) in the vicinity of the former 1,000-gallon gasoline UST, the former 550-gallon diesel UST, and the dispenser island in April 2019. An aromatic hydrocarbon fraction C9-C22 was detected above the Residential Maximum Soil Contaminant Concentrations (MSCCs) in the sample collected near the 550-gallon diesel UST (SS-02) at a concentration of 766.2 milligrams per kilogram (mg/kg).
Numerous petroleum constituents exceeded the soil-to-groundwater MSCCs in the soil samples collected from the dispenser island (SS-01) and the 550-gallon diesel UST (SS-02) locations. Groundwater WR collected groundwater samples from site monitoring wells MW-1, MW-2, MW-3, MW-4R,
MW-5, and MW-6 on May 9, 2023. The groundwater samples were submitted for laboratory analysis of volatile organic carbons (VOCs) by SM6200B.
• Laboratory analytical results indicated that no petroleum compounds analyzed exceeded
the Gross Contaminant Level (GCL).
• Laboratory analytical results indicated that monitoring wells MW-1, MW-2, and MW-3
contain 15A NCAC 2L Groundwater Quality Standards (2L Standards) exceedances.

• Laboratory analytical results indicated that monitoring wells MW-1, MW-2, and MW-3 contain 15A NCAC 02B Surface Water Standards (2B Standards) exceedances.

Light Non-Aqueous Phase Liquid (LNAPL) LNAPL was not measured in any of the monitoring wells sampled by WR in May 2023. LNAPL has not historically been detected at the site.
3. Receptor Information According to historical information, WSW-3 is the only active water supply well within 1,000-feet of the subject property.
Potable water is not available to the site and surrounding area. John’s River is located approximately 250-feet west of the source area and is located along the subject property boundary.
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:
• April and May 2022 – Injection of BOS 200+® was conducted near MW-1, MW-2, and MW-3.
5. Recommendations
Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following:
• If funding is available, install injection wells into the partially weathered rock for injection BOS 200+® in the areas of MW-1, MW-2, and MW-3.
• Semi-annual monitoring of MW-1, MW-2, MW-3, MW-4R, MW-5, and MW-6 and water supply well WSW-3.

SECTION C. SITE HISTORY AND CHARACTERIZATION WR has completed a groundwater sampling event for 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 is located at 5895 NC Highway 90 in Collettsville, Caldwell County, NC (Figure 1). The site is currently vacant and was formerly operated as a convenience store with commercial fuel
sales. USTs operating at the site have included one 550-gallon diesel UST, one 550-gallon kerosene UST, one 1,000-gallon gasoline UST, and one 2,000-gallon gasoline UST. The initial release was reported in September 1995 following the UST closure.

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 1995 – Haynes Engineering Associates submitted an Underground Tank Closure Report for the April 1995 UST removal of one 550-gallon diesel underground storage tank
(UST), one 550-gallon kerosene UST, and one 1,000-gallon gasoline UST, and one 2,000-gallon
gasoline UST that was closed in place. Closure samples indicated that TPH-GRO and TPH-DRO were above the regulatory action levels near the 550-gallon diesel UST, the 1,000-gallon gasoline UST and the dispenser island. Approximately 12 cubic yards of petroleum impacted soil were removed during the UST closure activities.

• April 2019 – As part of a Phase I Limited Site Assessment, Terracon advanced three soil borings (SS-1 through SS-3) in the vicinity of the former 1,000-gallon gasoline UST, the former 550-gallon diesel UST, and the dispenser island. An aromatic hydrocarbon fraction C9-C22 was
detected above the Residential MSCCs in the sample collected near the 550-gallon diesel UST
(SS-02) at a concentration of 766.2 mg/kg. Numerous petroleum constituents exceeded the soil-to-groundwater MSCCs in the soil samples collected from the dispenser island (SS-01) and the 550-gallon diesel UST (SS-02) locations. Monitoring well MW-1 was installed in boring SS-03 near the 1,000-gallon gasoline UST and MW-2 was installed in boring SS-01 near the dispenser island. Several petroleum compounds were detected above the 2L Standards in
MW-1 and MW-2.
• July 2019 – Terracon installed MW-3 and MW-4 and collected on soil sample (SS-04). Monitoring wells MW-1 through MW-4 and water supply well WSW-3 were sampled, and
several petroleum compounds were detected above the 2L Standards in MW-1 through MW-3. No petroleum compounds were detected above the 2L Standards in MW-4. No petroleum compounds were detected above the laboratory method detection limits (MDLs) in WSW-3. TPH-DRO and TPH-GRO were not detected above the MDLs in the soil sample.
• February 2020 – Terracon sampled monitoring wells MW-1 through MW-4 and water supply well WSW-3. Several petroleum compounds were detected above the 2L Standards in monitoring wells MW-1 through MW-3. No petroleum compounds were detected above the
2L Standards in MW-4. No petroleum compounds were detected above the MDLs in WSW-3.

• May 2020 – Terracon installed MW-5 and MW-6 and a replacement well MW-4R due the submerged well screen in MW-4. Several petroleum compounds were detected above the 2L Standards in monitoring wells MW-1 through MW-3 and benzene and naphthalene were
above 2L Standards in MW-6. No petroleum compounds were detected above the MDLs in MW-4R or MW-5. Toluene was detected below the 2L Standard in WSW-3 (0.78 micrograms per liter [µg/L]).
• December 2020 – Terracon sampled MW-1 through MW-3 and MW-4R through MW-6, WSW-3, and two surface water samples from John’s River (upgradient and downgradient of the source area). Petroleum compounds were slightly lower in MW-1 through MW-3, with

L.C. Hudspeth Store – NCDEQ Incident #17329 WR Project # 23-0307-FH Monitoring Report June 2023 6
several petroleum compounds above 2L Standards. No petroleum compounds were detected above the 2L Standards in MW-6. No petroleum compounds were detected above the MDLs in MW-4R, MW-5, or WSW-3.
• June 2021 – Terracon sampled MW-1 through MW-3 and WSW-3. Several petroleum compounds were above 2L Standards in MW-1 through MW-3 and no petroleum compounds were detected in WSW-3.

• April – May 2022 – Terracon oversaw the injection of BOS 200+® near MW-1, MW-2, and MW-3.
• August and November 2022 - Terracon conducted 3-month and 6-month post injection sampling events documented in the December 12, 2022 Post-Injection Groundwater Monitoring Report. The injection was not effective in reducing petroleum compounds below the 2L Standards in MW-1 and MW-2. Concentrations of petroleum compounds were below 2L Standards in MW-1 during the August and November 2022 sampling events. Terracon
recommended an additional injection event using pre-drilled boreholes drilled deeper into the partially weathered rock. 3. Brief Description of Site Characteristics
The property is located in a rural, residential area of Collettsville, Caldwell County, North Carolina (Figure 2). The property is currently vacant and was formerly operated as a convenience store with commercial fuel sales. The USTs and dispensers have been removed and/or closed in place. 4. Information on Receptors/Potential Receptors
According to historical information, WSW-3 is the only active water supply well within 1,000-feet of the subject property. Potable water is not available to the site and surrounding area.
John’s River is located approximately 250-feet west of the source area and is located along the subject property boundary. 5. Regional and Site Geology and Hydrology
According to the 1985 USGS Geologic Map of the State of North Carolina, the subject property is located within the Grandfather Mountain Window, a thrust-fault structure within the Blue Ridge Physiographic Province. The property is located on intrusive rocks consisting of biotite granitic gneiss interlayered with felsic metavolcanics and metasedimentary rocks.

According to well drilling logs, surficial soils between the surface and 20 feet below ground surface
(bgs) consists of light to dark brown and orange silt with clay to brown silty sand as apparent fill or
alluvium. Partially weathered rock was encountered in MW-5 and MW-6 at a depth of 13 feet bgs.

SECTION D. GROUNDWATER SAMPLING – May 2023 On May 9, 2023, WR personnel mobilized to the subject property to perform 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 existing monitoring wells MW-1, MW-2, MW-3, MW-4R, MW-5, and MW-6. The groundwater samples collected under TA-01 were submitted for laboratory analysis of VOCs by SM6200B. The following paragraphs describe the sampling activities and associated laboratory analytical
results. Groundwater Sampling Activities Prior to the purging and sampling of the site monitoring wells on May 9, 2023, WR personnel opened and gauged those wells targeted for purging and sampling with an electronic water level indicator to determine the depth to groundwater at each well location.
The depth to groundwater measurements in the monitoring wells ranged from 6.70 feet (ft) below the top of casing (ft-BTOC) in monitoring well MW-4R to 13.65 ft-BTOC in monitoring well MW-3. Based on data obtained during this sampling event, groundwater flow appears to trend to the west. This groundwater flow appears generally consistent with past assertions. A groundwater
hydraulic gradient map based on the May 9, 2023 measurements is included as Figure 3. Groundwater elevation data are included in Table B-7. Following gauging, monitoring wells were purged and sampled with separate, disposable polyethylene bailers for each well. Samples from the wells were decanted into pre-preserved
laboratory provided sample containers. Samples collected from site monitoring wells were submitted via courier under chain-of-custody procedures to Waypoint Analytical in Charlotte, NC for testing by SM6200B.
Laboratory Results
Analytical results for the groundwater samples collected on May 9, 2023, indicated that no petroleum compounds analyzed exceeded the GCL. Laboratory analytical results indicated that monitoring wells MW-1, MW-2, and MW-3 contain 2L Standards exceedances.
Laboratory analytical results indicated that monitoring wells MW-1, MW-2, and MW-3 contain 15A NCAC 02B Surface Water Standards (2B Standards) exceedances. Analytical data for MW-4R, MW-5, and MW-6 did not report any compounds above the method
detection limits.

The following table compares Total VOCs results from MW-1, MW-2, and MW-3 during the July 2019 event to data collected in May 2023.
Well ID Total VOCs July 2019 (µg/L)
Total VOCs May 2023 (µg/L)
Percent Reduction / Increase (-/+ %)
MW-1 6,443 4,773 -36.5%
MW-2 32,514 11,369 -65%
MW-3 1,132 116 -90%
Total VOC concentrations have reduced significantly since July 2019.

The following table compares Total VOCs results from MW-1, MW-2, and MW-3 from data collected in November 2022 to data collected in May 2023.
Well ID Total VOCs November 2022 (µg/L)
Total VOCs May 2023 (µg/L)
Percent Reduction / Increase (+/- %)
MW-1 4,885 4,773 -2.3%
MW-2 2,524 11,369 +350% MW-3 0.88 116 +13,127%
Total VOC concentrations changes between November 2022 to May 2023 show a slight decrease in MW-1 while MW-2 showed a significant increase. The April – May 2022 injection event appears
to have had a short-term effect of reducing petroleum compounds. Based on the increased concentrations of petroleum compounds in MW-2 and MW-3, the concentrations have rebounded in those monitoring wells. Analytical results are summarized in Table B-4 and illustrated on Figure 4. Benzene, ethylbenzene,
and naphthalene result maps are included as Figures 5, 6, and 7 respectively. Copies of the laboratory analytical report and chain-of-custody are included in Appendix A. A photographic record and field notes are included in Appendix B. Standard Operating Procedures are included in Appendix C.
SECTION E. CONCLUSIONS AND RECOMMENDATIONS This report documents the results of field activities conducted at the site for TA-01 which included
the purging and sampling of monitoring wells MW-1, MW-2, MW-3, MW-4R, MW-5, and MW-6. Conclusions based on observations, analytical data and research relating to the release at the site combined with historical information include the following:
• The site dispensers and three USTs were removed in April 1995. One 2,000-gallon gasoline UST was closed in place in April 1995.

Dear Flora D'Souza:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 5/10/2023 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 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.
