Groundwater Monitoring Report August 2023  3      SECTION B. EXECUTIVE SUMMARY    1. Summary of Activities Associated with Current TA    WithersRavenel, Inc. (WR), in association with Task Authorization‐01 (TA‐01) for the site, under  North Carolina Department of Environmental Quality (NCDEQ) Contract # N70522‐C,  completed assessment activities including the gauging, purging, and sampling of monitoring wells  MW‐1R through MW‐8 and DW‐1 associated with the release at the Handy Pantry of Liberty  site, located in Liberty, Randolph County, NC (Site).      2. Soil, Groundwater and LNAPL Assessment Information     Soils  No soil samples were obtained in association with the monitoring activities conducted by WR  during the July 2023 event. Based on historical information for the site, when the three original  USTs were removed from the site in October 2004, petroleum contamination was noted in the  soils surrounding the USTs, and 532 tons of soil was excavated during the closure. Soil samples  were collected from sidewalls and base of the final excavation limits; laboratory analysis of these  samples detected volatile organic compounds in all of the base soil samples and five of the eight  sidewall samples above Soil‐to‐Groundwater Maximum Soil Contaminant Concentrations  (MSCCs), but not above the Residential MSCCs.    Groundwater   Analytical results for groundwater samples obtained from site monitoring wells in July 2023  reported Gross Contamination Level (GCL) violations in groundwater samples from the following  monitoring wells MW‐4 and MW‐6. 15A NCAC 2L Groundwater Quality Standard (2L Standard)  exceedances were reported in monitoring wells MW‐1R and MW‐3 through MW‐8. Benzene  and methyl tert‐butyl ether (MTBE) were reported in well DMW‐1 at a concentration exceeding  the Method Detection Limit (MDL) but below the 2L Standard.     Light Non‐Aqueous Phase Liquid  Light non‐aqueous phase liquid (LNAPL) was detected in monitoring well MW‐2 at a thickness of  0.03 feet and has historically been detected in this well.    3.       Receptor Information    According to the Groundwater Monitoring Report by ECS dated November 15, 2019 and the  referenced August 2016 receptor survey, two potable water supply wells utilized by the Town of  Liberty are located within 1,000 feet of the source area: water supply wells WSW‐1 and WSW‐ 2. Water supply well WSW‐2 is sampled through the H&M Tire Service Incident #37686.  Municipal water supplied by the Town is available to all properties within 1,000 feet of the  source area. Based on distance from the source area of the release, current and historical  groundwater gradient, and historical sampling; water supply wells WSW‐1 and WSW‐2 do not  appear to be at risk of impacts from the Handy Mart of Liberty release.    Based on information obtained from the NCDEQ source water assessment program (SWAP)  website, the site is located within a wellhead protection area for the Town of Liberty: Wellhead  WithersRavenel Our People. Your Success.  Handy Mart of Liberty – NCDEQ Inc. #30208 WR Project # 23‐0307‐CI  Groundwater Monitoring Report August 2023  4      Protection (WHP) Plan No. 103.1; Public Water Supply ID #NC0276025. The WHP plan includes  nine water supply wells and serves a population of approximately 3,558.    4. Remediation Activities  In October 2004, during the removal of the three on‐site USTs (two 8,000‐gallon and one 4,000‐ gallon gasoline USTs), approximately 532 tons of petroleum contaminated soils were excavated  and removed from the site.    An Aggressive Fluid Vapor Recovery (AFVR) Event was performed on monitoring well MW‐2 in  August 2019. Prior to the event, 0.84 inches of LNAPL had been measured in monitoring well  MW‐2. The 8‐hour AFVR event recovered 510 gallons of petroleum‐impacted groundwater.     A second AFVR event was performed on monitoring wells MW‐2 and MW‐6 in May 2020. The  8‐hour AFVR event recovered 84 gallons of petroleum‐impacted groundwater.     No other remedial activities are known to have taken place on the site to date.    5. Recommendations  Based on the results of assessment and monitoring activities conducted at the site in association  with this TA, WR recommends the following:   Conduct an AFVR event on MW‐2 to remove LNAPL.   Continued sampling of site monitoring wells.   Explore remedial options to reduce concentration levels on‐site.    SECTION C. SITE HISTORY AND CHARACTERIZATION    The following information summarizes the site history and characterization.     1. UST Information    Two 8,000‐gallon gasoline USTs and one 4,000‐gallon gasoline UST were installed at the site on  April 9, 1982. During an integrity test of the UST system in October 2002, soil samples collected  in the vicinity of the UST system indicated concentrations of petroleum above the North  Carolina DWM UST Section action levels for total petroleum hydrocarbons. The three USTs  were closed by removal in October 2004. Perforations were noted at the fill port end of two  USTs upon removal. The tanks all displayed surface corrosion and pitting. After removing the  USTs, petroleum contamination was noted in the soils surrounding the USTs, and 532 tons of soil  was excavated during the closure. The quantity of the release is unknown.     A 15,000‐gallon double‐walled, compartmentalized UST with double‐walled product lines was  installed between October 19‐21, 2004. This UST is currently active on‐site and is located within  the same tank pit as the former UST system. Figure 2 shows the location of the historical UST  system and the layout of the current UST system and associated dispensers.     WithersRavenel Our People. Your Success.  Handy Mart of Liberty – NCDEQ Inc. #30208 WR Project # 23‐0307‐CI  Monitoring Report August 2023  5      Historical and current UST information is provided in Table 1. Photographs of site conditions  during July 2023 are included in Appendix A.      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:  • Site Check Report (September 15, 2003) by Shield Engineering, Inc. (Shield)   In October 2002, soil samples were collected in the vicinity of the UST system revealed  concentrations of total petroleum hydrocarbons (TPH) gasoline‐range organics (GRO) above  the NCDEQ DWM UST Section action levels. In 2003, a site check was performed and  included the advancement of 22 soil borings around the UST. Nine of the collected soil  samples exceeded the current NCDEQ Action Levels for TPH‐GRO. Samples were not  analyzed for risk‐based testing.     • Limited Site Assessment Phase I & II (May 21, 2004) by Shield.   In January 2004, one Type II groundwater monitoring well was installed in the area of  elevated petroleum hydrocarbon concentrations that was previously identified during the soil  sampling associated with the Site Check Report. The sample collected from monitoring well  MW‐1 in January 2004 identified multiple volatile organic hydrocarbons above the 2L  Standards, but none were above the GCLs. In March 2004, four additional monitoring wells  were installed; one upgradient, two downgradient, and one Type III deep well was installed  downgradient of the source area. Groundwater samples collected from these four new  monitoring wells detected one or more volatile organic compounds (VOCs) above the 2L  Standards with GCL exceedances in monitoring wells MW‐2 and MW‐4. Groundwater flow  was calculated to be toward the north‐northeast.    • Underground Storage Tank Closure Report (February 18, 2005) by Terraquest.  The three onsite USTs (UST‐1, UST‐2, UST‐3) were closed by removal and a 15,000‐gallon  compartmentalized UST was installed on site in October 2004. Perforations, corrosion, and  pitting was seen on UST‐1 and UST‐2 upon removal. Approximately 532 tons of soil was  excavated from the area of the USTs, but no soil was excavated around the dispenser island.  No perforations were noted in the product lines, but soil contamination was noted around  the piping joints. Soil samples were collected from sidewalls and base of the final excavation  limits; laboratory analysis of these samples detected volatile organic compounds in all of the  base soil samples and five of the eight sidewall samples above Soil‐to‐Groundwater MSCCs,  but not above the Residential MSCCs.     • Groundwater Monitoring Report (July 10, 2015) by ECS Southeast, LLP (ECS).   A groundwater monitoring event was conducted in April 2015. Groundwater samples from  monitoring wells MW‐1, MW‐3, and MW‐4 contained volatile organic compounds at  concentrations above the 2L Standards. LNAPL was present in monitoring well MW‐2 (3.51  feet). Monitoring well DMW‐1 was not sampled. A sample collected from municipal water  supply well WSW‐2 contained a concentration of trichloroethene (TCE) (0.9 µg/L) above  detection limits but below the 2L Standard. The Town of Liberty Public Works Director was  WithersRavenel Our People. Your Success.  Handy Mart of Liberty – NCDEQ Inc. #30208 WR Project # 23‐0307‐CI  Monitoring Report August 2023  6      notified, and he responded that TCE has historically been detected in WSW‐2 and that the  well is sampled on a regular basis by the Town and is also sampled as part of H&M Tire  Service Incident #37686.    • Groundwater Monitoring Report (December 19, 2016) by ECS.   Four additional Type II groundwater monitoring wells were installed at the site, and  monitoring well MW‐1 was replaced with monitoring well MW‐1R in August 2016.  Monitoring well MW‐2 again contained LNAPL (4.30 feet). A sample collected from water  supply well WSW‐2 contained concentrations of 1,1‐dichloroethene (0.60 µg/L);  tetrachloroethene (PCE) (0.52 µg/L); and TCE (1.2 µg/L) above method detection limits, but  below the 2L Standards. A Health Risk Evaluation was sent to the Town by NCDEQ, and no  restrictions were recommended.     • Groundwater Monitoring Report (November 15, 2019) by ECS.  An 8‐hour AFVR event was conducted on monitoring well MW‐2 in August 2019 by ECS. A  total of 510 gallons of petroleum‐impacted groundwater was removed from the monitoring  well, and a total of 6.68 pounds of LNAPL were emitted as vapor during the event. LNAPL  was not observed in the monitoring well three weeks after the event. ECS was unable to  obtain access agreements to install monitoring wells off‐site. Groundwater flow was  interpreted to be toward the southeast.     • LNAPL Recovery and Groundwater Monitoring Report (June 19, 2020) by ECS.   An 8‐hour AFVR event was conducted on monitoring wells MW‐2 and MW‐6 in May 2020  by ECS. A total of 84 gallons of petroleum‐impacted groundwater was removed from the  monitoring well, and a total of 0.048 pounds of LNAPL were emitted as vapor during the  event. LNAPL was not observed in the monitoring well three weeks after the event. Targeted  volatile organic compounds remained at concentrations above the 2L Standards and GCLs  after the AFVR event. Groundwater flow was interpreted to be toward the east‐northeast.     Annual Monitoring Report (February 19, 2021) by WithersRavenel.   WR conducted groundwater monitoring of the on‐site monitoring wells (MW‐1R through  MW‐8 and DMW‐1) as well as water supply wells WSW‐1 and WSW‐2 on January 12 and  13, 2021. Targeted volatile organic compounds remained at concentrations above the 2L  Standards in each site monitoring well. GCL violations were reported in groundwater samples  from monitoring wells MW‐4 and MW‐6. Chloromethane was reported at concentrations  above 2L Standards in water supply wells WSW‐1 and WSW‐2 and TCE was reported in well  WSW‐2 above method detection limits, but below the 2L Standards. Groundwater flow was  interpreted to be generally toward the east. Per the request of the NCDEQ UST Section, WR  re‐sampled water supply wells WSW‐1 and WSW‐2. Compounds were not detected in well  WSW‐1, and 1,1‐dichloroethane and TCE were detected in well WSW‐2.       WithersRavenel Our People. Your Success.  Handy Mart of Liberty – NCDEQ Inc. #30208 WR Project # 23‐0307‐CI  Monitoring Report August 2023  7       Annual Monitoring Report (September 16, 2022) by WithersRavenel.   WR conducted groundwater monitoring of the on‐site monitoring wells (MW‐1R through  MW‐8 and DMW‐1) in June 2022. Targeted volatile organic compounds remained at  concentrations above the 2L Standards in each site monitoring well with the exception of  DMW‐1. GCL violations were reported in groundwater samples from monitoring wells MW‐ 2, MW‐4, and MW‐6.       3.  Site Characteristics    The property is located in a commercial / industrial area with adjoining residential properties in  Liberty, Randolph County, North Carolina (Figure 1). The property is currently occupied and  operated as the Kwik Stop #3, an active gas station and convenience store (see Figure 2). The  Randolph County GIS website identifies the subject property as being assigned parcel  identification number 8736063690.    4.       Information on Receptors/Potential Receptors    According to the Limited Site Assessment Phase I & II Report completed by Shield in 2004, one  municipal water supply well, WSW‐2, exists within 500 feet of the site, and municipal one water  supply well, WSW‐1, exists within 1,000 feet of the site. Both wells supply the Town of Liberty.  Based on current groundwater flow, the water supply wells appear to be upgradient and side‐ gradient relative to the site. In 2015, TCE was detected in water supply well WSW‐2, and a  Health Risk Evaluation was provided by NCDEQ. In 2016, 1,1‐dichlorethene, PCE, and TCE were  detected in water supply well WSW‐2, and a Health Risk Evaluation was provided by NCDEQ.  No restrictions on well use were recommended. Chloromethane was detected in both water  supply wells above the 2L Standard during this January 2021 monitoring event, and TCE was  detected in water supply well WSW‐2 at a concentration below the 2L Standard.     Based on information obtained from the NCDEQ source water assessment program (SWAP)  website, the site is located within a wellhead protection area for the Town of Liberty. Wellhead  Protection (WHP) Plan No. 103.1; Public Water Supply ID #NC0276025. The WHP plan includes  nine water supply wells and serves a population of approximately 3,558 people.     Water supply well information is provided on Table B‐5A, and the locations of the wells are  shown on Figure 3.     5.       Regional and Site Geology and Hydrology    The Geologic Map of North Carolina depicts the site as being underlain by the Carolina Slate Belt  of the Piedmont Physiographic Province. Bedrock is characterized as felsic metavolcanic rock.   According to the United States Department of Agricultural (USDA) Natural Resources  Conservation Service (NRCS) Web Soil Survey, the source area is underlain by Georgeville‐Urban  land complex (2 to 10 percent slopes). Georgeville‐Urban land complex soils are well drained,  found on interfluve summits, and the parent material is residuum weathered from metavolcanics

and/or argillite. The boring logs for monitoring wells MW‐2 through MW‐5 indicated the  predominant soil types at the site are silt and sandy silt to depths of at least 20 feet bgs.     SECTION D. GROUNDWATER SAMPLING – JULY 2023  On July 19, 2023, WR personnel mobilized to the subject property to sample monitoring wells  MW‐1R through MW‐8 and DMW‐1. The following paragraphs describe the sampling activities  and associated laboratory analytical results.     Prior to the purging and sampling of site monitoring wells, as described below, WR personnel  opened and gauged each well targeted for sampling with an electronic LNAPL/water level  indicator to determine whether measurable LNAPL was present, and to measure the depth to  groundwater within each of the wells. LNAPL was detected in monitoring well MW‐2 at a  thickness of 0.03 feet.     The depth to groundwater measurements in the monitoring wells gauged at the site on July 19,  2023, the site ranged from 14.30 feet below the top of casing (BTOC) in monitoring well MW‐7  to 21.45 feet‐BTOC in monitoring well DMW‐1. Based on groundwater elevation  measurements, groundwater flow across the site appears to be generally to the southeast which  is generally consistent with historical groundwater flow direction. The groundwater table  contours are depicted on Figure 4. Monitoring well construction information is included in Table  B‐7. Groundwater elevation measurement data for this and previous events are presented in  Table B‐9. Field notes are included in Appendix A.  Following gauging, the monitoring wells were purged and sampled using separate, disposable  polyethylene (PE) bailers for each well. The containers were labeled with appropriate information  and the groundwater samples were transported in an ice‐chilled cooler under proper chain‐of‐ custody Waypoint Analytical, Inc. for testing by Standard Method (SM) 6200B plus oxygenates.    Laboratory Results  Analytical data for groundwater samples obtained from site monitoring wells on July 19, 2023,  reported:   Benzene exceeded the GCL in the samples collected from monitoring well MW‐4.   Benzene and 1,2‐dibromoethane exceeded the GCLs in the sample collected from  monitoring well MW‐6.   Various petroleum constituents were reported exceeding 2L Standards in monitoring  wells MW‐1R and MW‐3 through MW‐8.    Benzene and MTBE were reported in well DMW‐1 at a concentration exceeding the  MDL but below the 2L Standard.    Current and historical groundwater analytical results are summarized in Table B‐4 and current  data is shown on Figure 5. A dissolved benzene isoconcentration contour map is included as  Figure 6.     The laboratory report and chain‐of‐custody associated with these samples are included in  Appendix B.  Standard operating procedures are included in Appendix C.    WithersRavenel Our People. Your Success.  Handy Mart of Liberty – NCDEQ Inc. #30208 WR Project # 23‐0307‐CI  Monitoring Report August 2023  9      SECTION E. CONCLUSIONS AND RECOMMENDATIONS  This report documents the results of field activities conducted at the site for TA‐01 which  included gauging, purging, and sampling monitoring wells MW‐1R through MW‐8 and DMW‐1.  Based on this sampling event and historical assessment activities at the site indicate the  following:     The site is currently operating as a retail fuel dispensing facility called the Kwik Stop #3.   LNAPL was identified in MW‐2 at a thickness of 0.03 feet.   Benzene and/or 1,2‐dibromomethane were reported in wells MW‐4 and MW‐6 at  concentrations exceeding GCLs.   Analytical results for samples collected from site monitoring wells in July 2023 reported one  or more VOCs above the 2L Standards in samples obtained from MW‐1R and MW‐3 through  MW‐8.    Benzene and MTBE were reported in well DMW‐1 at a concentration exceeding the MDL  but below the 2L Standard.   Groundwater elevation data recorded on July 19, 2023, indicates a groundwater flow pattern  across the site that flows generally to the southeast.      The extents of the plume are not defined to levels equivalent to the 2L Standard.  Based on the results of assessment and monitoring activities conducted at the site in association  with this TA, WR recommends the following:   Conduct an AFVR event on MW‐2 to remove LNAPL.   Continued sampling of site monitoring wells.   Explore remedial options to reduce concentration levels on‐site.  WithersRavenel Our People. Your Success.      FIGURES     500' 1000' 1500' (3,720)(<0.500) (4,120)(14,700) (5,600)(19,400)(4.96)

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.
