SECTION B. EXECUTIVE SUMMARY
1. Summary of Activities Associated with Current TA
WithersRavenel, Inc. (WR) advanced two soil borings (WR-1 and WR-2), installed one monitoring well in soil boring (WR-2), and conducted a groundwater sampling event at the Former Big D #420 site located at 3532 US Highway 64 East in Hayesville, Clay 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 collecting soil samples from two soil borings, installation of monitoring well MW-10,
surveying the top of casing (TOC) elevation of MW-10, and gauging, purging, and sampling of monitoring wells MW-1, MW-2, and MW-10. 2. Soil, Groundwater, and LNAPL Assessment Information

Soils Two soil samples were collected by WR in association with this task authorization. One soil sample (WR-1) was collected at a depth of 5’ to 8’ near MW-1 and one soil sample (WR-2) was collected from a depth of 5’ to 7.5’ in the boring that was completed at MW-10. The soil samples were submitted for laboratory 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). Benzene and methyl tert-butyl ether (MTBE) were detected at concentrations in excess of Soil-to-Water Maximum Soil Contaminant Concentrations (MSCCs) in sample WR-1. Several petroleum compounds were detected above the laboratory method detection limits (MDLs), but below the Soil-to-Water
MSCCs in WR-1. No petroleum compounds were detected above the MDLs in sample WR-2. Soil samples collected during the Limited Site Assessment (LSA) indicated that several volatile organic compounds (VOCs) and VPH were above the soil-to-water MSCCs in the soil sample collected during the installation of monitoring well MW-1.
Twenty-one soil borings (SB-1 through SB-21) were installed during the Comprehensive Site Assessment (CSA) activities. Soil samples SB-1 through SB-8, SB-10, SB-11, SB-13, and SB-16 through SB-18 contained concentrations of VOCs and/or VPH above the soil-to-water MSCCs. No petroleum compounds were detected above the residential MSCCs. Based on information in
the CSA, soil contamination extended approximately 25 feet laterally around the former release and up to 13 feet below ground surface (bgs). According to the Underground Storage Tank (UST) Closure Report by Altamont Environmental, Inc. (Altamont) dated June 3, 2014, soil samples were not obtained. The Work Plan approved by
the North Carolina Department of Environment and Natural Resources (NCDENR, now NCDEQ)
stated that if no obvious new release was observed, sampling would not be required to be collected beneath the USTs.

Groundwater WR collected groundwater samples from monitoring wells MW-1, MW-2, and MW-10 on June 2, 2023. The groundwater samples were submitted for laboratory analysis of VOCs by SM6200B.
Laboratory analytical results for monitoring well MW-1 indicated the presence of benzene slightly above the 15A NCAC 02L 0202 (2L) Standard. Several additional petroleum-related compounds were reported above the MDL, but below the 2L Standard in MW-1. Naphthalene was reported at a concentration above the MDL, but below the 2L Standard in monitoring well
MW-2. Toluene was reported at a concentration above the MDL, but below the 2L Standard in monitoring well MW-10. No compounds were reported at concentrations that exceeded the gross contamination levels (GCLs) established by NCDEQ.
Water Supply Wells
WR collected samples from the on-site water supply well WSW-8 and an off-site water supply well WSW-6. The owner of WSW-4 was not at home and had not returned the access agreement prior to the June 2023 sampling event, therefore, WSW-4 was not sampled. An access agreement was left with the daughter of the WSW-4 property owner on June 2, 2023. The samples from the water supply wells and a field blank were submitted for analysis of VOCs
by SM6200B.
Analytical results for the samples collected from the water supply wells did not indicate targeted VOCs at concentrations exceeding the laboratory’s MDLs.

Light Non-Aqueous Phase Liquid
Historically, light non-aqueous phase liquid (LNAPL) has not been documented in the on-site monitoring wells. No LNAPL was measured in the monitoring wells MW-1, MW-2, or MW-10 in June 2023.
3. Receptor Information
A receptor survey was conducted by Geological Resources, Inc. in 2003 during the LSA activities and a receptor survey update was performed by Alpha Environmental (Alpha) in May 2022. The receptor survey update identified eight private water supply wells within 500 feet of the source area, six private water supply wells between 500 feet and 1,000 feet of the source area, and one
water supply well was identified between 1,000 and 1,500 feet of the source area. Water supply well WSW-1 is inactive, and WSW-2 has been abandoned. Municipal water is not available in the vicinity of the site. Chatuge Lake is located approximately 1,000 feet to the southeast 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:

Former Big D #420 – NCDEQ Incident #28081 WR Project # 23-0307-FC Groundwater Monitoring Report July 2023 5
• May 2014 – Two 8,000-gallon gasoline USTs and one 6,000-gallon gasoline UST were removed on May 5 and May 8, 2014. The source of the petroleum contaminants was
reportedly from a gasoline product line associated with the 6,000-gallon gasoline UST
discovered in February 2003. 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:

• Annual sampling of the monitoring wells MW-1 and MW-2 and water supply wells WSW-4, WSW-6, and WSW-8.
SECTION C. SITE HISTORY AND CHARACTERIZATION
The following information summarizes the site history and assessment. 1. UST Information
The site is located at 3532 US Highway 64 East in a residential/agricultural district in Hayesville,
Clay County, North Carolina (Figure 1). The site is currently occupied by an inactive convenience store/petroleum retail facility. Two 8,000-gallon gasoline USTs and one 6,000-gallon gasoline UST were removed in May 2014. Based on information in the 2004 CSA, soil contamination extended approximately 25 feet laterally around the former release and up to 13 feet below
ground surface (bgs).
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:

• February 2003 – The release was reported when gasoline odors were observed in WSW-1. WSW-1 is not currently in use; however, the WSW has not been abandoned.
• September 2003 – An LSA was completed at the site by Geological Resources, Inc. Two soil samples were collected during the installation of MW-1. Several petroleum compounds exceeded the soil-to-water MSCCs in the soil sample collected at 5 feet bgs and benzene was above the soil-to-water MSCC in the soil sample collected at 20 feet bgs. Four Type II
monitoring wells (MW-1 through MW-4) and one Type III monitoring well (TW-1) were
installed. Multiple petroleum compounds were detected in MW-1 and MW-2 that exceeded the 2L Standards. None of the compounds detected were above the GCLs. A receptor survey was conducted.
• June/July 2004 - A CSA was completed that included the installation twenty-one soil borings
(SB-1 through SB-21). Soil samples SB-1 through SB-8, SB-10, SB-11, SB-13, and SB-16

Former Big D #420 – NCDEQ Incident #28081 WR Project # 23-0307-FC Groundwater Monitoring Report July 2023 6
through SB-18 contained concentrations of VOCs and/or VPH above the soil-to-water MSCCs. No petroleum compounds were detected above the residential MSCCs. Based on information in the CSA, soil contamination extended approximately 25 feet laterally around the former release and up to 13 feet below ground surface (bgs). Five Type II monitoring
wells (MW-5 through MW-9) were installed. One or more petroleum compounds exceeded the 2L Standards in MW-1, MW-2, and MW-4.
• May 2014 – According to the Altamont UST Closure Report, two 8,000-gallon gasoline USTs
and one 6,000-gallon gasoline UST were removed on May 5 and May 8, 2014. The source of
the petroleum contaminants was reportedly from a gasoline product line associated with the 6,000-gallon gasoline UST discovered in February 2003; therefore, soil samples were not collected beneath the USTs. Previous reports indicated that the line was repaired and the gasoline in the UST was removed and replaced with diesel fuel.
• Periodic groundwater monitoring of the site monitoring wells has occurred from 2014 through 2022. Monitoring wells MW-1 and MW-2 have contained one or more petroleum compound above the 2L Standards during the majority of the sampling events (MW-1 reportedly only contained MTBE above the laboratory MDLs, but below the 2L Standard in August 2018 and September 2019). Monitoring well MW-2 was not sampled between 2017
and 2021.
• Water supply wells WSW-1, WSW-2, WSW-3, WSW-4, WSW-6, and/or WSW-8 were periodically sampled between June 2004 and May 2022. MTBE was detected in WSW-6 below 2L Standards in February 2015 at a concentration of 0.99 µg/L and 2.9 µg/L in
September 2019. No other petroleum compounds were detected during any other WSW sampling event.
• May 2022 – A receptor survey update was performed by Alpha. The update identified eight
private water supply wells within 500 feet of the source area, six private water supply wells
between 500 feet and 1,000 feet of the source area, and one water supply well was identified between 1,000 and 1,500 feet of the source area. Water supply well WSW-1 is inactive, and WSW-2 has been abandoned. Municipal water is not available in the vicinity of the site.

3. Brief Description of Site Characteristics The subject property is located at 3532 US Highway 64 East in a residential/agricultural district in Hayesville, Clay County, North Carolina (Figure 2).

4. Information on Receptors/Potential Receptors A receptor survey was conducted by Geological Resources, Inc. in 2003 during the LSA activities and a receptor survey update was performed by Alpha in May 2022. The receptor survey update
identified eight private water supply wells within 500 feet of the source area, six private water
supply wells between 500 feet and 1,000 feet of the source area, and one water supply well was identified between 1,000 and 1,500 feet of the source area. Water supply well WSW-1 is inactive, and WSW-2 has been abandoned. Municipal water is not available in the vicinity of the site.

Chatuge Lake is located approximately 1,000 feet to the southeast of the source area.

5. Regional and Site Geology and Hydrology The Geologic Map of North Carolina depicts the site within the Blue Ridge Belt of the Blue Ridge
Physiographic Province. The site is underlain by middle Proterozoic to late Proterozoic biotite
gneiss, biotite-garnet gneiss, amphibolite, quartz, and alumino-silicates.

According to the United States Department of Agricultural (USDA) Natural Resources
Conservation Service (NRCS) Web Soil Survey, the source area is underlain by Tate loam (2 to 8
percent slopes) and Hayesville clay loam (8 to 15 percent slopes). Tate loam is well drained,
found on coves, fans, and drainageways, and the parent material is colluvium derived from
igneous and metamorphic rock. Hayesville clay loam is well drained, found on ridges, and the
parent material is residuum weathered from hornblende gneiss and/or amphibolite.

According to the CSA, soil at the site consists of silts and clays. Soils obtained during the
installation of MW-10 and boring WR-1 consisted of clayey sand and sandy clay. Groundwater
ranges from a depth of 11.11 feet bgs to 12.72 feet bgs at the site based on the June 2023
sampling event.

SECTION D. SOIL SAMPLING – JUNE 2023

On June 1, 2023, WR personnel along with a licensed driller from AmeriProbe, LLC (Ameriprobe) advanced one soil boring near monitoring well MW-1 and one soil boring (WR-2) prior to installation of monitoring well MW-10 in the same borehole. Soil borings WR-1 and WR-2 were advanced using direct-push technology. Macrocores were collected at 5-foot intervals and the
samples were further split into 2.5-foot intervals. The soil samples were then screened using a
PID. Soil Sampling Activities Soil samples were collected at depths of 5.0 to 8.0 feet bgs in WR-1 and from 5.0 to 7.5 feet bgs
in WR-2. The soil samples were submitted to a certified laboratory for the analysis of the Risk-
Based Rule Parameters: EPA Method 8260 and MADEP Method for VPH. Laboratory Results Benzene and MTBE were detected at concentrations in excess of Soil-to-Water MSCCs in
sample WR-1. Several petroleum compounds were detected above the laboratory MDLs, but
below the Soil-to-Water MSCCs in WR-1. No petroleum compounds were detected above the MDLs in sample WR-2. These results are shown on Figure 3 and included in Table B-3. Copies of the laboratory
analytical report and chain-of-custody are included in Appendix A. Field notes and site
photographs are included in Appendix B.

SECTION E. MONITORING WELL INSTALLATION – JUNE 2023 On June 1, 2023, WR personnel along with Ameriprobe mobilized to the site to install one Type II monitoring well, MW-10, within the former UST basin via geoprobe with hollow stem auger
attachments. MW-10 was installed to a depth of 15 feet bgs with a 10-foot length of 2-inch diameter Schedule 40 PVC 10-slot well screen and a 5-foot length of Schedule 40 PVC 2-inch diameter casing. The well was completed with a concrete collar/pad and 8-inch diameter flush-mount manway. Field notes and site photographs are included in Appendix B. The boring logs and well completion record are included in Appendix C. The monitoring well location is shown
on Figure 2.
Following completion, the well was developed with a disposable bailer. The top-of-casing elevation for monitoring well MW-10 was surveyed. WR’s generalized standard operating procedures are provided in Appendix D.
SECTION F. GROUNDWATER SAMPLING – JUNE 2023
On June 2, 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, MW-2, and MW-10.
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 June 2, 2023, WR personnel opened and gauged the monitoring 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, MW-2, and MW-10 ranged from 11.11 feet below the top of casing in MW-10 to 12.72 feet below the top of casing in MW-2. The depth to water was measured within the screened interval. Based on the measured
groundwater elevations, groundwater flow direction is to the southwest. A groundwater flow map is included as Figure 4. Groundwater elevation 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, MW-2, and MW-10, and a field blank were submitted to Waypoint Analytical, Inc. for testing by SM 6200B. Laboratory Results Laboratory analytical results for monitoring well MW-1 indicated the presence of benzene
slightly above the 15A NCAC 02L 0202 (2L) Standard. Several additional petroleum-related compounds were reported above the MDL, but below the 2L Standard in MW-1. Naphthalene was reported at a concentration above the MDL, but below the 2L Standard in monitoring well MW-2. Toluene was reported at a concentration above the MDL, but below the 2L Standard in

monitoring well MW-10. No compounds were reported at concentrations that exceeded the gross contamination levels (GCLs) established by NCDEQ.
Water Supply Wells
WR collected samples from the on-site water supply well WSW-8 and an off-site water supply well WSW-6. The owner of WSW-4 was not at home and had not returned the access agreement prior to the June 2023 sampling event, therefore, WSW-4 was not sampled. An access agreement was left with the daughter of the WSW-4 property owner on June 2, 2023. The samples from the water supply wells and a field blank were submitted for analysis of VOCs
by SM6200B.
Analytical results for the samples collected from the water supply wells did not indicate targeted VOCs at concentrations exceeding the laboratory’s MDLs.
These results are shown on Figure 5 and included in Table B-4. Copies of the laboratory analytical report and chain-of-custody are included in Appendix A.

SECTION G. CONCLUSIONS AND RECOMMENDATIONS This report documents the results of field activities conducted at the site for TA-01, which
included the installation of two soil borings (WR-1 and WR-2) and one monitoring well (MW-10) and the top-of-casing elevation survey for MW-10, purging and sampling of monitoring wells MW-1, MW-2, and MW-10. Conclusions based on observations, analytical data, and historical information include the following:
• The site is currently an inactive convenience store/petroleum retail facility.
• Municipal water is not available in the vicinity of the site.
• Eight water supply wells or well head protection areas were identified within a 500-foot radius of the source area.
• Six water supply wells were identified between a 500 and 1,000-foot radius of the source
area.
• Benzene was reported at a concentration that exceeded the 2L Standard in monitoring well MW-1. Several petroleum compounds were detected above the laboratory MDLs, but below the 2L Standard.
• Analytical results for the samples collected from water supply wells WSW-6 and WSW-8 did not indicate targeted VOCs at concentrations exceeding the laboratory’s MDLs. Based on the results of the assessment activities conducted at the site in association with this
TA, WR recommends the following:

• Annual sampling of the monitoring wells MW-1 and MW-2 and water supply wells WSW-4, WSW-6, and WSW-8.

Dear Flora D'Souza:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 6/6/2023 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.
