1. Summary of Activities Associated with Current TA    WithersRavenel, Inc. (WR) gauged, purged and sampled groundwater monitoring wells MW‐1,  MW‐2, MW‐3, MW‐4R, MW‐5, MW‐6, MW‐7, MW‐8, MW‐9R, MW‐13, TW‐1R and TW‐2.   WR was originally tasked with the additional collection of a groundwater samples from MW‐14R  and TW‐3, however, neither of these wells were located by WR personnel, and were, therefore,  not sampled.      2. Soil, Groundwater and Free Product Assessment Information    Soils  No soil samples were obtained by WR in association with this task authorization. Results for soil  samples collected during previous assessment activities at the site relating to USTs closed at the  location during May 1990 have shown levels of gasoline range organics (GRO) and diesel range  organics (DRO) as total petroleum hydrocarbons (TPH) at concentrations exceeding the minimum  Reportable Concentration (RC) or NCDEQ Action Levels in place at the times of sample  collection.  Laboratory results for soil samples collected in association with UST closures  completed in March 2019 did not show levels of TOH at concentrations exceeding the NCDEQ  Action Levels.      Groundwater  Analytical data for groundwater samples obtained from site monitoring wells in December 2019  showed one or more targeted compounds at levels exceeding their respective 2L Standards in  MW‐1, MW‐2, MW‐3, MW‐4, MW‐7, MW‐9R and TW‐2.  Levels of n‐propylbenzene (MW‐2,  MW‐3) and naphthalene, 1,2,4‐trimethylbenzene, 1,3,5‐trimethylbenzene and total xylenes  (MW‐3) were reported at concentrations in excess of their respective Gross Contaminant Levels  (GCLs).  Levels of one or more compounds reported in samples from MW‐2 and MW‐3 were  shown at concentrations to be 10‐times their respective NC 2B Surface Water Standards.        Apparent contaminant increases in MW‐3 may relate to possible increased groundwater  movement following the removal of UST systems to the north of the source area in March 2019.      Based on current groundwater data for wells sampled during December 2019, the extent of  groundwater contamination at the facility has not been defined to levels equivalent to the 2L  Standards to the East of MW‐7.  In addition, previous data for MW‐14R (North of MW‐7) have  shown levels of select compounds at levels above 2L Standards.      Free Product  Free product has been documented by previous consultants in monitoring wellsMW‐1, MW‐3,  MW‐7 and MW‐9.  No free product was measured in any monitoring wells during the December  2019 sampling event, however, a representative of Waypoint Analytical Services (Waypoint), the  laboratory which analyzed groundwater samples collected during December 2019 stated that  there was a petroleum sheen on the samples collected from MW‐3.          Former Underwood Grocery  Incident # 27715  WR Project # 02171214.27  Subsequent Monitoring Report    January 2020    3      3. Receptor Information    WR did not perform a receptor update in association with the current task authorization for the  site.  According to historical reports, several supply wells were identified within 1,500‐ft of the  site, however, following the installation of a municipal water supply system to the site and  surrounding properties, no potable water supply wells are known to exist within 1,000 feet of  the source area. Additionally, there are no irrigation wells located within 250 feet of the source  area. Three surface water bodies are located within 1,000 feet of the source area. The closest  surface water body is an unnamed tributary to Prince Mill Creek located approximately 150 feet  north of the source area. Price Mill Creek is located approximately 850 feet northeast of the  source area. The third is a pond located approximately 900 feet south‐southeast of the source  area.    4. Remediation Activities    Remedial activities performed at the site, to date, have included the following:     December 2007: An Aggressive Fluid Vapor Recovery (AVFR) event was conducted on  groundwater monitoring wells MW‐3 MW‐9 and MW‐7. During the event, 934 gallons of  fluid, and 17 gallons of free product was recovered.   February 2012: 326.20 tons of impacted soil was removed from the former dispenser island  area and the former UST basin and disposed offsite at a NC permitted facility.   August 2013: An AFVR event was completed on the subject site and on groundwater  monitoring wells MW‐2, MW‐7, MW‐9R and TW‐2. A total of 2,529 gallons of liquid and 14  gallons of free product were removed from the aquifer.   March 2019: Four petroleum USTs were permanently closed through removal.  Results for  soil samples collected at the time of these closures did not show evidence of a release or  releases from these systems.      5. Recommendations    Based on the results of assessment and monitoring activities conducted at the site in association  with this TA, WR recommends the following:     Resampling of MW‐2 and MW‐3 to verify GCL exceedances.   If concentrations confirmed, removal of impacted soils in the areas of MW‐2 and MW‐3 to  address GCL exceedances.      Former Underwood Grocery  Incident # 27715  WR Project # 02171214.27  Subsequent Monitoring Report    January 2020    4    C. SITE HISTORY AND CHARACTERIZATION    WR completed groundwater sampling activities at the facility on December 9, 2019. The  following information summarizes the site history and characterization.      1 UST Information    UST Systems Closed in 1990  The approximate location of the former underground storage tank (UST) systems removed from  the site in 1990 are is depicted on Figure 2. The former UST system consisted of four USTs; (1)  8,000‐gallon UST, (2) 1,000‐gallon gasoline USTs, (1) 550‐gallon kerosene UST, which were  removed from the site in 1990.      UST Systems Closed in March 2019  Following closure of the UST systems on the property in 1990, four additional tanks, including  (1) 8,000 gallon, (1) 4,000 gallon, (1) 3,000‐gallon gasoline USTs, and (2) 2,000‐gallon USTs used  to store diesel and kerosene.  These tanks were closed though removal in March 2019.  Table B‐ 1 includes information regarding the USTs formerly located on the property.     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:     April 1990: four USTs (1) 2,000‐gallon and (2) 1,000‐gallon gasoline USTs and (1) 550‐ gallon kerosene UST were removed from the site.   (Between) 1990 and 2004: five USTs were installed on the property which included; (1)  8,000 gallon, (1) 4,000 gallon, (1) 3,000‐gallon gasoline USTs, and (2) 2,000‐gallon USTs  used to store diesel and kerosene.   May 2004: Monitoring wells MD W‐1, MW‐2, MW‐3 are installed. Soil samples were  collected from well boreholes MW‐1, MW‐2, and MW‐3 and submitted to a laboratory  for analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and MADEP  VPH and EPH. Analytical results for the soil samples collected did not identify targeted  compounds at concentrations exceeding Soil‐to‐Water MSCCs. Groundwater monitoring  well MW‐3 contained 0.01 feet of free product. Groundwater samples were collected  from MW‐1 and MW‐2 and submitted to a laboratory for analysis of VOCs by EPA  Method 602, EDB by EPA Method 504.1, total lead by Standard Method (SM) 6010, and  MADEP VPH and EPH.  Analytical results for MW‐1 and MW‐2 identified one or more  analytes at concentrations exceeding their respective 2L Groundwater Standard.   February 2005: 26 soil samples were collected from 21 soil borings that were advanced  proximal to the current UST basin. The soil samples were analyzed for total petroleum  hydrocarbons (TPH) gasoline range organics (GRO) and diesel range organics (DRO).  Analytical results for the one or more soil samples collected identified TPH GRO or DRO  at concentrations exceeding the NC Action Levels in place at the time of the assessment.   July 2005: Soil and groundwater assessment activities were conducted onsite which  included the advancement of one soil boring and four groundwater monitoring wells.  Three Type II groundwater monitoring wells (MW‐4 through MW‐6) and one Type III  groundwater monitoring well (TW‐1) were installed onsite. Groundwater samples were  collected from each groundwater monitoring well (MW‐1 through MW‐6 and TW‐1) and    Former Underwood Grocery  Incident # 27715  WR Project # 02171214.27  Subsequent Monitoring Report    January 2020    5    submitted to a laboratory for analysis of VOCs by EPA Method 602, EDB by EPA Method  504.1, total lead by SM6010, and MADEP VPH and EPH. Analytical results for  groundwater samples collected in MW‐1, MW‐2, MW‐6 and TW‐1 identified one or  more analytes at concentrations exceeding their respective 2L Groundwater Standards.  Three soil samples were collected from two soil borings (MW‐6 and SS‐22 at the five‐  and ten‐foot intervals) and submitted to a laboratory for analysis of VOCs by EPA  Method 8260, SVOCs by EPA Method 8270, MADEP VPH and EPH. Analytical results  for the three soil samples did not identify targeted compounds exceeding the Soil‐to  Water MSCCs.   December 2007: An Aggressive Fluid Vapor Recovery (AVFR) event was conducted on  MW‐3, MW‐9 and MW‐7. During the event, 934 gallons of fluid, and 17 gallons of free  product was recovered.   May 2011: Residential homes located at 6608 and 6711 Weddington Road were  connected to municipal water and their water supply wells were abandoned, thus, no  potable water supply wells are present with 1,000 feet of the source area.    February 2012: 326.20 tons of impacted soil was removed from the former dispenser  island area and the former UST basin and disposed offsite at a NC permitted facility.   August 2013: an AFVR event was completed at the site during which a vacuum was  pulled on groundwater monitoring wells MW‐2, MW‐7, MW‐9R and TW‐2. A total of  2,529 gallons of liquid and 14 gallons of free product were removed from the aquifer.   May 2014: a groundwater sampling event was conducted which included the sampling all  existing groundwater monitoring wells (Type II monitoring wells MW‐1, MW‐2, MW‐4,  MW‐6, MW‐7, MW‐9R, MW‐12, and MW‐13, Type III monitoring wells TW‐2 and TW‐ 3). In addition, a surface water sample (SW‐2) was collected from the unnamed tributary  to Prince Mill Creek which is located ~150 feet northwest of the source area. Analytical  results for groundwater samples collected from monitoring wells MW‐1, MW‐2, MW‐4  MW‐6, MW‐7, MW‐9R, MW‐12, MW‐13, TW‐2 and TW‐3 identified one or more  petroleum related compounds at concentrations exceeding the 2L Groundwater  Standards. Analytical results for the water sample collected from the unnamed tributary  to Prince Mill Creek did not identify any targeted compounds at a concentration  exceeding their respective laboratory detection limits, with the exception of MTBE.   February 2018: a groundwater sampling event was conducted on 15 groundwater  monitoring wells MW‐1 through MW‐8, MW‐9R, MW‐12, MW‐13, MW‐14R, TW‐1R,  TW‐2, and TW‐3. Analytical data for groundwater samples collected in shallow wells  MW‐1, MW‐2, MW‐3, MW‐4, MW‐6, MW‐7, MW‐9R, MW‐14R, and deep wells TW‐2  and TW‐3 identified one or more petroleum related compound at concentrations  exceeding their respective 2L Standards.   March 2019: WR Oversaw the excavation and removal of three gasoline USTs of 8,000,  4,000 and 3,000‐gal. capacities, one diesel fuel UST of 2,000‐gal. capacity and one  kerosene UST of 2,000‐gal. capacity.  Laboratory results for soil samples collected in  association with these UST closures did not show levels of TOH at concentrations  exceeding the NCDEQ Action Levels.      3.   Brief Description of Site Characteristics    The property is located in a residential and commercial area of Wesley Chapel, Union County,  North Carolina (Figure 1). The property address associated with the Incident is 6709  Weddington Road. The property includes a single‐story commercial building of block  construction located on the southwestern portion of the property and a residential house    Former Underwood Grocery  Incident # 27715  WR Project # 02171214.27  Subsequent Monitoring Report    January 2020    6    located in the southeastern corner of the property (Figure 2). The building on site is surrounded  by concrete and asphalt pavement and areas of grass and dirt. The Union County parcel  identification number for the property is 06045016E01. The Union County Tax Department  indicates that the property is currently owned by Ammons Investments, LLC.     According to the 1985 Geologic Map of North Carolina, the site is located in the Carolina Slate  Belt of the Piedmont Physiographic Province. Subsurface lithology in the region consists of Late  Proterozoic age weakly metamorphosed sedimentary and volcanic rocks. The metamorphic rocks  beneath the site and surrounding area primarily include phyllite, a fine‐grained sericitic rock with  pervasive cleavage and a silky luster. The phyllite, and tuffaceous interbeds within it are believed  to be strongly sheared, recrystallized beds of the Tillery or Cid Formations which are comprised  of argillite, mudstone, siltstone, and ryolitic and ryodacitic tuffs.      The undisturbed soils encountered in this area are the residual product of in‐place chemical  weathering of rock which was similar to the rock presently underlying the site. In areas not  altered by erosion or disturbed by the activities of man, the typical residual soil profile consists of  near surface clayey soils and underlying sandy silts and silty sands. The boundary between soil  and rock is typically gradational. A transitional zone termed "partially weathered rock" is normally  found overlying the parent bedrock.    Examination of the U.S. Geological Survey 7.5‐minute series topographic maps of Matthews and  Waxhaw, North Carolina Quadrangles, the site is located approximately 590 feet above mean  sea level with a topographic relief to the north, towards an unnamed tributary to Prince Mill  Creek (Figure 1).    4.   Information on Receptors/Potential Receptors    WR did not perform a receptor update in association with the current task authorization for the  site.  According to the Phase II Limited Site Assessment (LSA) completed by CBM Environmental  Services in August 2005, several supply wells were present within the radius for their receptor  survey, however, each of the supply wells located within 1,000‐ft of the site have since been  abandoned, following the installation of a municipal water line.  Presently, there are no potable  water supply wells within 1,000 feet of the source area. Additionally, there are no irrigation wells  located within 250 feet of the source area.     Three surface water bodies are located within 1,000 feet of the source area. The closest surface  water body is an unnamed tributary to Prince Mill Creek located approximately ~150 feet north  of the source area. Price Mill Creek is located approximately 850 feet northeast of the source  area. The third is a pond located approximately 900 feet south‐southeast of the source area.  Information pertaining to the surface water bodies within 1,000 feet of the source area are  summarized in Table B‐5B.  Each of these features drain to the Catawba River Basin.        Former Underwood Grocery  Incident # 27715  WR Project # 02171214.27  Subsequent Monitoring Report    January 2020    7      D. PRESENTATION OF CURRENT/COMPARISON TO HISTORICAL ASSESSMENT  INFORMATION    On December 9, 2019, WR personnel mobilized to the subject site to perform assessment and  sampling activities in accordance with task authorization TA‐04 for the facility. WR personnel  gauged, purged and sampled groundwater monitoring wells MW‐1, MW‐2, MW‐3, MW‐4R,  MW‐5, MW‐6, MW‐7, MW‐8, MW‐9R, MW‐13, TW‐1R and TW‐2.  WR was originally tasked  with the additional collection of a groundwater samples from MW‐14R and TW‐3, however,  neither of these wells were located by WR personnel, and were, therefore, not sampled.      1 Groundwater Elevations    Prior to the purging and sampling of site monitoring wells, WR personnel opened and gauged  monitoring wells with an electronic water level indicator to determine the depth to groundwater  at each well location.  Groundwater elevations measured within the wells on December 9, 2019  ranged from 12.69‐ft beneath the wells top‐of‐casing (BTOC) in MW‐13 to 15.17‐ft BTOC in  TW‐2.  Groundwater elevations were utilized to generate a two‐dimensional representation of  the groundwater table at the site based on the December 2019 measurement of groundwater  levels (Figure 3).  Groundwater elevation data indicates that groundwater flows to the north,  with a westerly component on the northeastern portion of the site.  Groundwater elevations as

Groundwater Sampling and Analytical Results    Monitoring Well Sampling   WR personnel obtained groundwater samples from MW‐1, MW‐2, MW‐3, MW‐4R, MW‐5,  MW‐6, MW‐7, MW‐8, MW‐9R, MW‐13, TW‐1R and TW‐2 following gauging and purging.   Following the gauging of the wells and prior to sampling each of the wells were purged of a  minimum of three volumes of groundwater through the use of separate, disposable bailers, as  described in the procedures outlined in Appendix D.      Samples were collected from each well following purging and recovery of groundwater and  decanted directly from the dedicated bailers into laboratory prepared sample containers holding  appropriate preservative(s) as required.  The containers were labeled with appropriate  information and the groundwater samples were transported in an ice‐chilled cooler under proper  chain‐of‐custody to Waypoint located in Charlotte, NC for analysis by SM6200B.  Copies of field  notes associated with monitoring activities are included in Appendix A.    Former Underwood Grocery  Incident # 27715  WR Project # 02171214.27  Subsequent Monitoring Report    January 2020    8      Analytical Results  Analytical data for groundwater samples obtained from site monitoring wells in December 2019  showed the following:     One or more targeted compounds at levels exceeding their respective 2L Standards in MW‐ 1, MW‐2, MW‐3, MW‐4, MW‐7, MW‐9R and TW‐2.     Levels of n‐propylbenzene (MW‐2, MW‐3) and naphthalene, 1,2,4‐trimethylbenzene, 1,3,5‐ trimethylbenzene and total xylenes (MW‐3) were reported at concentrations in excess of  their respective GCLs.     Levels of one or more compounds reported in samples from MW‐2 and MW‐3 were shown  at concentrations to be 10‐times their respective NC 2B Surface Water Standards.        Groundwater analytical results are summarized in Table B‐4 and included on Figure 4.  Figure 5  illustrates isoconcentration contours for benzene, while Figure 6 shows naphthalene  concentrations in groundwater.  The laboratory analytical report and chain‐of‐custody record are  included in Appendix A.         Former Underwood Grocery  Incident # 27715  WR Project # 02171214.27  Subsequent Monitoring Report    January 2020    9        E.  CONCLUSIONS AND RECOMMENDATIONS    This report documents the results of field activities conducted at the site in December 9, 2019  including gauging, purging and sampling groundwater monitoring wells MW‐1, MW‐2, MW‐3,  MW‐4R, MW‐5, MW‐6, MW‐7, MW‐8, MW‐9R, MW‐13, TW‐1R and TW‐2.  Conclusions based  on completion of the site groundwater assessment activities include the following:     The property is currently unoccupied and out‐of‐service.     The subject property and surrounding properties have access to and are reportedly serviced  by a municipal water supply system.     Current data suggests that groundwater flow is to the north in the central portion of the site,  with a northwesterly trend indicated near the northeastern part of the property.     No free product was measured in any monitoring wells gauged in December 2019.   One or more targeted compounds at levels exceeding their respective 2L Standards in MW‐ 1, MW‐2, MW‐3, MW‐4, MW‐7, MW‐9R and TW‐2.     Levels of n‐propylbenzene (MW‐2, MW‐3) and naphthalene, 1,2,4‐trimethylbenzene, 1,3,5‐ trimethylbenzene and total xylenes (MW‐3) were reported at concentrations in excess of  their respective GCLs.     Levels of one or more compounds reported in samples from MW‐2 and MW‐3 were shown  at concentrations to be 10‐times their respective NC 2B Surface Water Standards.      Based on concentrations of compounds exceeding GCLs and NC 2B Surface Water  Standards, site risk remains High.      Based on the results of assessment activities conducted at the site in association with the  current TA, WR recommends the following:     Resampling of MW‐2 and MW‐3 to verify GCL exceedances.   If concentrations confirmed, removal of impacted soils in the areas of MW‐2 and MW‐3 to  address GCL exceedances.

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.

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.                         APPENDIX E    HISTORICAL GROUNDWATER DATA
