Summary of Activities Associated with Current TA WithersRavenel, Inc. (WR) supervised the installation of two monitoring wells, sampled the five monitoring wells at the site, and installed one 4” remediation well and three 2” air sparge wells at the Foothills Service Center site located at 312 East Union Street in Morganton, Burke County, North Carolina in association with task authorization TA‐04 under North Carolina Department of Environmental Quality (NCDEQ) Contract #N122019B. 2. Soil, Groundwater and LNAPL Assessment Information Soils During the installation of monitoring well MW‐8 on February 2, 2023, WR collected a risk‐based soil sample from the interval below the fill and above the water table identified as SB‐1 (20‐25). This soil sample contained naphthalene above the Industrial/Commercial Maximum Soil Contaminant Concentration (MSCC) and several compounds above the Soil‐to Groundwater and Residential MSCCs. In addition, as part of a potential property transaction, S&ME advanced fourteen soil samples throughout the site and on the adjacent property. The soil samples collected in the vicinity of the former underground storage tank (UST) system exhibited concentrations above the Soil‐to‐Groundwater and Residential MSCCs, but not the Industrial/Commercial MSCCs. These soil samples were collected between 15 and 25 feet below ground surface. Groundwater S&ME collected groundwater samples from MW‐4 through MW‐6 on February 1, 2023. WR collected samples from groundwater monitoring wells MW‐1 through MW‐5 and MW‐7 and MW‐ 8 on February 2, 2023. Monitoring well MW‐1 had 0.05 feet of light non‐aqueous phase liquid (LNAPL) present and was not sampled. The groundwater samples from monitoring wells MW‐2 through MW‐8 were submitted for laboratory analysis of volatile organic compounds (VOCs) by SM 6200B. Laboratory analysis of the groundwater samples collected from MW‐7 indicated benzene and 1,2‐ dibromoethane above the Gross Contamination Levels for Groundwater (GCLs) and MW‐8 had benzene above its GCL. Monitoring wells MW‐2, MW‐3, MW‐4, MW‐7, and MW‐8 detected one or more petroleum compounds above the North Carolina 2L Groundwater Quality Standards (2L Standards). Liquid Non‐Aqueous Phase Liquid LNAPL was detected in monitoring well MW‐1 at a thickness of 0.05 feet during the February 2, 2023 sampling event. WithersRavenel Our People. Your Success. Foothills Service Center – NCDEQ Inc. #20326 WR Project # 02171214.68 Groundwater Monitoring Report March 2023 4 3. Receptor Information The area within 1,500‐feet of the subject property is supplied potable water by the Town of Morganton Municipal Water System. WR is not aware of any surface water bodies within 500‐ feet of the subject property. 4. Remediation Activities Based on WR’s review of historical files available for the site, the following remedial activities have been completed at the site:  Six 560‐gallon USTs, one 1,000‐gallon UST, one 1,200‐gallon UST, and one 2,000‐gallon UST were removed from the subject property on March 23‐31, 2020. A total of 828.99 tons of petroleum‐impacted soil were removed the property during the UST removal.  In January 2022, WR conducted a Mobile Multi‐Phase Extraction (MMPE) event at the site utilizing MW‐1. During the MMPE event, eight gallons of LNAPL and 2,206 gallons of VOC‐ impacted water were recovered and transported offsite for disposal. Based on mass removal calculations, 1,083.28 pounds of VOCs or 176.09 gallons of VOCs were removed as vapor during the event.  WR conducted two MMPE’s in March 2023, one the week of March 6, 2023 and one the following week. The MMPEs will be documented in a separate report. 5. Recommendations Based on the results of the activities conducted at the site in association with this TA, WR recommends the following:  Performing a sampling event to include monitoring wells MW‐1 through MW‐3 and MW‐7 and MW‐8 to determine if the MMPEs conducted March 6, 2023 and March 13, 2023 were effective.

SITE HISTORY AND CHARACTERIZATION The following information summarizes the site history and characterization. 1. UST Information In September 2000, seven USTs (UST‐1 through UST‐6, and UST‐9) were emptied and closed in place using foam. In January 2020, WR conducted a ground‐penetrating radar (GPR) survey to identify the locations of the closed‐in‐place USTs. In March 2020, WR completed the closure by removal of the UST systems which included six 560‐gallon USTs, one 1,000‐gallon UST, one 1,200‐gallon UST, and one 2,000‐gallon UST. Information regarding the USTs is summarized on Table B‐1. 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 1997 ‐ Phase II–Abandoned UST Study, LAW Engineering and Environmental Services, Inc. (LAW) LAW completed underground locating and confirmed the presence of five USTs, one UST was present in one tank basin and the remaining four identified USTs were in an additional tank basin. LAW collected soil samples around the two UST basins. Results indicated the presence of TPH‐ GRO exceeding the current NCDEQ Action Level in four of the seven soil samples collected. The groundwater samples collected from the soil borings indicated the presence of impacts above the 2L Standards in each of the six samples with the GCL for benzene exceeded in four of the six groundwater samples. LAW personnel did not identify water supply wells on the site or adjacent properties and the area is served by municipal water. September 2000 – UST Removal and Abandonment, Royster Oil Company, Inc. (Royster) Royster abandoned‐in‐place seven USTs using foam and removed one 550‐gallon UST in the triangle formed by the intersection of Lenoir Street and East Union Street. February 2020 – Initial Groundwater Monitoring Report (WR) WR performed a GPR survey and collected soil and groundwater samples. The GPR survey identified five USTs at the site. Soil sampling indicated the petroleum release appears to be concentrated near the former dispenser island and its adjacent tanks and that soil contamination extends to the groundwater table at approximately 25 feet bgs. The groundwater plume appears to be primarily concentrated near the dispenser island. May 2020 – Initial Abatement Action Report (WR) WR supervised the removal of nine USTs consisting of six 560‐gallon USTs, one 1,000‐gallon UST, one 1,200‐gallon UST, and one 2,000‐gallon UST between March 23 and 31, 2020. Two additional USTs were identified during the UST removal activities in the UST basin previously thought to contain one UST. A total of 828.99 tons of petroleum‐impacted soils were removed from the site during the UST closure activities and transported off‐site for treatment and disposal. Exceedances WithersRavenel Our People. Your Success. Foothills Service Center – NCDEQ Inc. #20326 WR Project # 02171214.68 Groundwater Monitoring Report March 2023 6 of the Soil‐to‐Groundwater and Residential MSCCs were observed in the soil samples collected from Excavation 1 and Excavation 4. Excavation 1 encompassed the dispensers and USTs 1 through 4 and extended to approximately 18‐20 feet bgs and Excavation 4 included USTs 7, 8 and 9 and extended to approximately 7 feet bgs. September 2020 – Subsequent Monitoring Report (WR) WR installed and collected samples from monitoring wells MW‐1 through MW‐3 on July 14, 2020. The groundwater sample collected from monitoring well MW‐1 indicated benzene and EDB above the GCL. Multiple contaminants were identified above the 2L Standards in monitoring wells MW‐ 1 through MW‐3. LNAPL was not observed in the site monitoring wells. The groundwater flow direction was determined to be to the south, generally towards an unnamed tributary of Hunting Creek approximately 920 feet to the southeast. February 2021 – Annual Monitoring Report (WR) WR collected samples from monitoring wells MW‐1 through MW‐3 on January 20, 2021. The groundwater sample collected from monitoring well MW‐1 indicated benzene and EDB remained above the GCL. Multiple contaminants were identified above the 2L Standards in monitoring wells MW‐1 through MW‐3. LNAPL was not observed in the site monitoring wells. August 2021 – Corrective Action Feasibility Study (WR) Based on the observed soil and groundwater concentrations, LNAPL was determined to likely be present at the site. Therefore, WR recommended a surfactant‐enhanced injection and MMPE event. Since EDB was not likely to be addressed by this approach, WR recommended treating the remaining contaminant mass via a carbon‐based injection such as Trap & Treat BOS 200®, PetrofixTM, or similar injectates. March 2022 – Subsequent Monitoring Report (WR) On January 24 through 28, 2022, WR supervised a MMPE event. Prior to the MMPE event, the depth to LNAPL and groundwater measurements in MW‐1 were 27.60 feet below the top of casing (ft‐BTOC) and 27.99 ft‐BTOC, respectively, for a LNAPL thickness of 0.39 feet. During the radius of influence gauging conducted on January 28, 2022, as part of the MMPE event, LNAPL was detected in monitoring well MW‐2 at a thickness of 0.07 feet. Approximately eight gallons of LNAPL and 2,206 gallons of VOC‐impacted water were recovered and transported offsite for disposal. Based on mass removal calculations, 1,083.28 pounds of VOCs or 176.09 gallons of VOCs were removed as vapor during the event. WR mobilized to the site on March 2, 2022 to sample three Type II groundwater monitoring wells. Monitoring well MW‐1 contained LNAPL at a thickness of 0.41 feet and was not sampled. Laboratory analysis of the groundwater samples collected from monitoring wells MW‐2 and MW‐ 3 identified one or more petroleum compounds above the 2L Standards, but not the GCLs.

Site Characteristics The site is located in an urban (commercial) area of Morganton, Burke County, NC (Figure 1), addressed as 312 East Union Street. This property is indexed by the Burke County GIS system as Burke County Real Estate ID #31519, NC PIN 2703372877. The property encompasses approximately 0.27 acres of land and is utilized as a parking area for the City of Morganton. The property is bounded along its eastern side by White Street, and to the north by East Union Street. The site is bordered to the south and west by undeveloped grass lots. Eight Type II monitoring wells associated with assessment activities performed at the site are located at the site as shown on Figure 2. Natural gas, water and sanitary sewer services to the location are provided through buried lines. Electrical service is provided overhead. Stormwater drainage is provided through man‐made conveyances (e.g., buried lines, drop inlets). Surface runoff is channeled through these stormwater conveyances. 4. Information on Receptors/Potential Receptors The area within 1,500‐feet of the subject property is supplied potable water by the Town of Morganton Municipal Water System. WR is not aware of surface water bodies within 500‐feet of the subject property. Evaluation of the Morganton, NC, Topographic Quadrangle (US Geological Survey, 7.5 Minute Series, 2019) and 2‐ft elevation contours provided by the Burke County GIS Service indicate that the subject property is at an approximate elevation of 1,172 feet above mean sea level (AMSL) at the center of the subject property. A scaled portion of the USGS Quadrangle is included as Figure 1. Topography at the site slopes primarily to the southeast. 5. Regional and Site Geology and Hydrology The Geologic Map of North Carolina (Department of Natural Resources, Division of Land Resources, North Carolina Geologic Survey, 1985) shows materials underlying the site to consist of “migmatitic granitic gneiss” of Cambrian‐Ordovician age, within intrusive rocks of the Inner Piedmont, Chauga Belt, Smith River Allochthon, and Sauratown Mountain Belts. Base materials at the site location are indexed as “foliated to massive, granitic to quartz dioritic; biotite gneiss and amphibolite common.” The site is adjacent to what is mapped as “biotite gneiss and schist” of Late Proterozoic‐Cambrian age, with metamorphic rocks of the Inner Piedmont, Chauga Belt, Smith River Allochthon, and Sauratown Mountain Belts. Base materials in this area are indexed as “inequigranular, locally abundant potassic feldspar and garnet; interlayered and gradational with calc‐silicate rock, sillimanite‐mica schist, and amphibolite and contains small masses of granitic rock.” According to the United States Department of Agricultural (USDA) Natural Resources Conservation Service (NRCS) Web Soil Survey, the source area is underlain by urban land soils. Urban land is defined as impervious layers over human‐transported material. Boring log and excavation records from the site indicate that the general lithology of the site soils consists of micaceous silts and clayey silts. WithersRavenel Our People. Your Success. Foothills Service Center – NCDEQ Inc. #20326 WR Project # 02171214.68 Groundwater Monitoring Report March 2023 8 SECTION D. SOIL SAMPLING – FEBRUARY 2023 On January 30 and 31, 2023, S&ME mobilized to the site and collected eighteen soil samples as part of a potential property transaction. The soil samples collected in the vicinity of the former UST system exhibited concentrations above the Soil‐to‐Groundwater and Residential MSCCs. These soil samples were collected between 15 and 25 feet below ground surface. On February 2, 2023, WR personnel collected a soil sample during the installation of monitoring well MW‐8. The interval collected from 20 to 25 ft‐bgs indicated the highest photoionization detector reading. Therefore, this sample was submitted to Waypoint Analytical, Inc. located in Charlotte, NC, for analysis by Environmental Protection Agency (EPA) Method 8260 and Massachusetts Department of Environmental Protection (MADEP) Volatile Petroleum Hydrocarbons (VPH). Analytical results indicated that the naphthalene concentration exceeded the Industrial/Commercial MSCC. Several other petroleum concentrations were above the Soil‐ to‐Groundwater and Residential MSCCs. Soil analytical results are summarized in Table B‐3 and shown in Figure 3. Field notes and photographs are included in Appendix A. The laboratory analytical report is included in Appendix B. SECTION E. MONITORING WELL INSTALLATION– JANUARY & FEBRUARY 2023 On January 30 and 31, 2023, S&ME mobilized to the site and installed three Type II groundwater monitoring wells (MW‐4, MW‐5, and MW‐6) as part of a potential property transaction. On February 2, 2023, WR personnel and AmeriProbe, LLC mobilized to the subject property to install monitoring wells MW‐7 and MW‐8 in association with TA‐04 under NCDEQ Contract # N122019B. Prior to the monitoring well installation, Probe Utility Locating, LLC provided utility locating services at the site. Type II monitoring wells MW‐7 and MW‐8 were installed via 4.25‐ inch hollow stem augers to a depth of 33 feet bgs. Refusal was not encountered during the installation of MW‐7 and MW‐8. Both monitoring wells were installed with a 15‐ft length of 2‐ inch diameter Schedule 40 PVC 10‐slot well screen and an 18‐ft 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 photographs are included in Appendix A. The boring logs and well construction records are included in Appendix C. The locations of the monitoring wells are shown on Figure 2. Well construction details are included in Table B‐7. Following completion, the well was developed by bailing the entire volume of the well and borehole several times until the turbidity cleared. Monitoring wells MW‐7 and MW‐8 were surveyed into the monitoring well network after installation. SECTION F. GROUNDWATER SAMPLING – FEBRUARY 2023 WR mobilized to the site on February 2, 2023, to sample monitoring wells MW‐1 through MW‐3 and MW‐7 and MW‐8. Monitoring well MW‐1 contained LNAPL at a thickness of 0.05 feet and was not sampled. The locations of monitoring wells MW‐1 through MW‐8 are shown on Figure 2. WithersRavenel Our People. Your Success. Foothills Service Center – NCDEQ Inc. #20326 WR Project # 02171214.68 Groundwater Monitoring Report March 2023 9 Prior to purging activities, groundwater levels were gauged with a decontaminated electronic water interface meter. Groundwater levels measured within the monitoring wells ranged from 25.85 ft‐BTOC in monitoring well MW‐5 to 26.85 ft‐BTOC in monitoring well MW‐3. The monitoring wells were screened across the water table. Groundwater elevations in MW‐7 and MW‐8 were inconsistent with the previous groundwater measurements and the depth to water was re‐measured on February 28, 2023 and remained inconsistent. Groundwater elevations were utilized to generate a groundwater flow map at the site, based on the March 2023 groundwater levels (Figure 4). Groundwater elevation data indicated that groundwater flows to the southeast in the vicinity of the source area. Groundwater elevations and well construction information is summarized in Table B‐7. After gauging all wells, monitoring wells MW‐2, MW‐3, MW‐7, and MW‐8 were purged a minimum of three volumes of groundwater using dedicated bailers. Groundwater samples were then placed directly into laboratory‐provided containers, placed on ice, and under property chain‐ of‐custody procedures, transported to Waypoint Analytical, Inc. located in Charlotte, NC, to be analyzed for VOCs by SM6200B. Laboratory Results Monitoring well MW‐7 contained benzene and 1,2‐dibromoethane above the GCLs and MW‐8 had benzene above its GCL. Laboratory analysis of the groundwater samples collected from monitoring wells MW‐2, MW‐3, and MW‐4 detected one or more petroleum compounds above the 2L Standards. A summary of the groundwater analytical results is presented in Table B‐4 and shown on Figure 5. A benzene isoconcentration map is included as Figure 6. A photographic record and the field notes are included in Appendix A. A copy of the laboratory analytical report and chain‐of‐custody is included in Appendix B. WR’s standard operating procedures are provided in Appendix D. SECTION G. REMEDIAL WELL INSTALLATION – FEBRUARY 2023 On February 27, 2023, WR personnel along with Geologic Exploration (GEX) mobilized to the site to install one 4‐inch groundwater recovery well and three 2‐inch air sparge wells via hollow stem auger. The 4‐inch diameter recovery well was installed to a depth of 40 feet with 15 feet of screen. The 2‐inch diameter air sparge wells were installed to depths of 40 feet each with five feet of screen. Each well was completed with a concrete collar/pad and 8‐inch diameter flush‐mount manway. Schedule 40 PVC 10‐slot well screen was used for the intervals indicated above and Schedule 40 PVC casing was placed from the ground surface to the depth indicated for the screened portion. The boring logs are included in Appendix C. Well construction records have not been received from GEX as of the date of this report and will be sent under separate cover. Remediation well locations are shown on Figure 2. Construction information for the monitoring and remediation wells is included in Table B‐7. Following completion, the wells were developed with a downhole well pump. WithersRavenel Our People. Your Success. Foothills Service Center – NCDEQ Inc. #20326 WR Project # 02171214.68 Groundwater Monitoring Report March 2023 10 SECTION H. NOTICE OF INTENT On February 21, 2023, WR submitted a Notice of Intent to the NCDEQ Division of Water Resources (DWR) Groundwater Resources Section to inject air during the MMPE event. Approval was granted and permit #WI0100677 was issued. A copy of the Notice of Intent is included in Appendix E. SECTION I. CONCLUSIONS AND RECOMMENDATIONS This report documents the results of field activities conducted at the site for TA‐04, which included the installation of two Type II monitoring wells (MW‐7 and MW‐8), a groundwater sampling event, the installation of one 4” recovery well (RW‐1) and three 2” air sparge wells (AS‐1, AS‐2, and AS‐ 3). Conclusions based on observations, analytical data and research relating to the release at the site combined with historical information include the following:  The soil remedial goals for the site are the Industrial/Commercial MSCCs. The soil sample collected from soil boring SB‐1 at the interval of 20‐25 feet bgs which was below the excavation depth and above the soil‐groundwater interface. This soil sample contained naphthalene above the Industrial/Commercial MSCC.  The groundwater remedial goals are the GCLs. The presence of LNAPL in monitoring well MW‐1 represents an exceedance of the GCLs. MW‐1 has previously exhibited GCL exceedances of benzene and 1,2‐dibromoethane. During the February 2023 sampling event, MW‐7 and MW‐8 had GCL exceedances of benzene and MW‐7 had GCL exceedance of 1,2‐ dibromoethane.  The site is currently utilized as a parking lot by the City of Morganton.  Contaminant concentrations in monitoring wells MW‐2 through MW‐6 did not exceed the GCLs. Based on the results of assessment and monitoring activities conducted at the site in association with this TA, WR recommends the following:  Performing a sampling event to include monitoring wells MW‐1 through MW‐3 and MW‐7 and MW‐8 to determine if the MMPEs conducted March 6, 2023 and March 13, 2023 were effective.

Your Success. APPENDIX D WR’S STANDARD OPERATING PROCEDURES Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. 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. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. 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. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. 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. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. 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. WithersRavenel Our People. Your Success.
