A groundwater sampling event conducted on January 18, 2023 for the Perth Mini Mart release incident reveals the continued presence of over four feet of free-phase product, GCL violations, and 2L Standard violations. The site is ranked a High Risk based on the presence of nineteen sole-source active water supply wells located within 1,000 feet of the incident. As the NCDWM-UST has previously approved a Corrective Action Plan Feasibility Study and Corrective Action Design Report that details a sparge and vent treatment system, Terraquest recommends the preparation of a Record of Decision to implement active remediation. Semi- annual groundwater monitoring should continue until the treatment system is activated. Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 1 Troutman, Iredell County, North Carolina 1.0 INTRODUCTION On behalf of Madhukunj, LLC, Terraquest Environmental Consultants, P.C. (Terraquest) this Groundwater Monitoring Report has been prepared as requested by the Mooresville Regional Office of the NCDWM-UST for the Perth Mini Mart property located in Troutman, Iredell County, North Carolina.. Pre-approval of costs was made by the NCDWM-UST on ePATA 40784-017. The site location is depicted in Figure 1. The site vicinity is depicted in Figure 2. The site layout and monitoring well network are depicted in Figure 3. Technical methods and standard procedures generally utilized by Terraquest are detailed in Appendix A. 2.0 UPDATE OF SITE HISTORY AND CHARACTERIZATION A detailed chronological site history is provided in Appendix B. 2.1 UST Owner: The USTs are owned by Madhukunj, LLC. 2.2 Tank and Release Information: According to the NC UST Database Records, two 6,000-gallon gasoline, one 4,000-gallon gasoline, and one 2,000-gallon diesel USTs were installed at the site on March 4, 1980. Note that the 2,000-gallon diesel UST was converted to non-ethanol gasoline in 2018. A 2,000-gallon diesel AST is also present onsite. The installation date of that tank is unknown. All USTs were closed via excavation and removal in February 2019 as previously reported. Following closure, two new 12,000-gallon, gasoline, compartmentalized USTs were installed. A site history of the USTs and AST on the property is included as Table 1. Previous tank locations are shown on Figure 3. In 2017, the UST owner noted inventory record discrepancies based upon ATG reading for UST T3, the 4,000-gallon gasoline tank. In response, the UST owner submitted an UST-17A UST Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 2 Troutman, Iredell County, North Carolina Suspected Release 24-Hour Notice Form. The date and nature of the release is unknown but inventory records show a shortage of approximately 300-400 gallons. Based on the lab results of soil samples from beneath the other two gas USTs in the T3 basin, a release occurred from those tanks also. Terraquest is not aware of any AST release incidents. The site and several properties in the area are commercial in nature with the remaining majority used as residential as shown here: SITE Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 3 Troutman, Iredell County, North Carolina The closest residence is located approximately 330 feet north of the release area. There are no places of public assembly within 1,500 feet. Land use in the vicinity of the site is highway business and residential. The site and properties to the east are zoned Highway Business (HB). Most of the remaining properties are zoned Residential (RS). Zoning classifications of the site and surrounding properties are depicted on Figure 2 and below as taken from Iredell County’s GIS online system at https://iredell.connectgis.com. Initial abatement of the release included the removal of fuel from the T3 UST and placing it in temporary closure. All tanks were subsequently closed via removal. Environmental assessment activities were previously detailed in a Site Check Report, LSA Report, CSA Report, and CAP Feasibility Study sent to the NCDWM-UST. Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 4 Troutman, Iredell County, North Carolina 2.3 Receptor Information As part of the LSA and to determine the risk classification of the site, Terraquest personnel previously performed a reconnaissance of properties within a 1,500-foot radius of the source area. The reconnaissance effort consisted of obtaining tax department and local zoning information on properties and conducting door-to-door visits of certain properties within 1,500 feet of the source area, in addition to collecting other pertinent information from the appropriate local and state officials. Terraquest personnel inspected all properties within 1,500 feet of the site and attempted to contact all the property owners within 1,000 feet in person. Property owners within a 500 -foot radius were questioned, if available, as to the source of their water and if any water supply wells were located on their property. If owners/occupants were not home, a survey form was left at their residence or forwarded to the property owners through the mail. In all cases, Terraquest also conducted a visual survey of the property. Table 2 lists the names and addresses of surrounding property owners. Note that the PIN Numbers presented in Table 2 correspond with those shown in Figure 2. Terraquest has previously contacted the Town of Troutman’s Public Works Department to inquire about the Town’s water supply system. Terraquest was put into contact with West Consultants, PLLC, who maintains and operates the municipal supply system. Todd Poteet of West Consultants, PLLC, verified water lines are available along Perth Rd. and Autumn Leaf Rd.; however, not along Weddington Ln. Furthermore, since the subject area is not located within the jurisdictional boundary of the Town of Troutman, property owners are not required to connect to the municipal water supply system. Most are not interested in doing so as they would be annexed into Troutman and its associated taxes. Through the reconnaissance efforts, a total of thirty-three water supply wells were identified within 1,500 feet or the source area. Of those identified wells, nineteen are sole source water Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 5 Troutman, Iredell County, North Carolina supply wells located within 1,000 feet. One additional active water supply well is located on the site within 250 feet of the source area. That well is used to fill minnow tanks at the store. Water supply well information is listed in Table 3. Supply well locations are depicted on Figure 2. As part of the reconnaissance effort, Terraquest also searched for any surface water bodies within a 500-foot radius of the site. An unnamed tributary of Big Branch originates off the western property boundary of the site and is located within 500 feet of the source area. The NC Division of Water Quality (DWQ) classifies Big Branch as a Water Supply-IV “Waters used as sources of water supply for drinking, culinary, or food processing purposes.” The unnamed tributary of Big Branch is depicted on Figure 2. 2.4 Regional Geology and Hydrogeology The site is in the Piedmont Physiographic Region of North Carolina. According to the Geologic Map of North Carolina (Brown, et al, 1985), the site is in the Charlotte Belt and is underlain by mafic metavolcanic bedrock lithologies. On a regional scale, the Piedmont is characterized by land with moderate relief and some areas of low relief hills and valleys. Groundwater in the region is part of the Catawba River Basin. Regionally, groundwater flows to the southwest and feeds into Big Branch Creek and ultimately Lake Norman. Big Branch Creek is listed as a Water Supply IV surface water body at https://deq.nc.gov/about/divisions/water- resources/planning/classification-standards/classifications#DWRPrimaryClassification which classifies surface water bodies with a WSIV classification as “sources of water supply for drinking, culinary, or food processing.” Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 6 Troutman, Iredell County, North Carolina The site’s location in reference to nearby water bodies as provided by the NCDEQ at https://ncdenr.maps.arcgis.com/apps/webappviewer/index.html?id=6e125ad7628f494694e25 9c80dd64265 follows: SITE SITE Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 7 Troutman, Iredell County, North Carolina 2.5 Site Geology and Hydrogeology ENCOUNTERED LITHOLOGY The following lithologies were encountered at the site during the installation of soil borings and the monitoring well network: 0 – 63’ BGL SILT (CL) Mostly soft to medium-stiff (generally increasing consolidation with depth), micaceous, red to brown to tan, with trace clay and characteristics of saprolite in areas. 63-70’ BGL SAPROLITE Mostly tan/brown heavily-weathered rock. The drilling locations of the monitoring wells used to describe the lithology are depicted on Figure 3. Geologic cross sections of the site are based upon the soil boring logs are as follows: Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 8 Troutman, Iredell County, North Carolina Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 9 Troutman, Iredell County, North Carolina Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 10 Troutman, Iredell County, North Carolina Depth-to-water measurements have been collected from the monitoring wells during various stages of the assessment to estimate the direction of groundwater flow. Groundwater elevation measurements were reduced to a common datum by surveying the relative elevation of the top of the casing for each monitoring well. The water table elevation data as measured on January 18, 2023 was used to create a potentiometric surface map which illustrates the interpreted direction and gradient of groundwater flow that is generally to the south, southwest. Recent groundwater elevation data and monitoring well construction information is provided in Table 4. Historical groundwater elevation data is provided in Appendix C. The groundwater elevation measurements from April 30, 2019 reveal that the hydraulic head within the shallow phreatic aquifer ranged from a relative value of 66.61 at monitoring well MW5 to 67.91 at MW4. In conjunction with other site measurements, the results indicate flow in the phreatic aquifer in a south/southwest direction under an average hydraulic gradient of approximately 0.02. Water level data from the Type III monitoring well (MW11) and the interpreted groundwater elevation in the phreatic aquifer in the vicinity of the Type III well (based on MW5) were used to determine if a vertical head gradient existed in the phreatic aquifer. The vertical head gradient was calculated using the following equation and groundwater elevation data collected on April 30, 2019: Vg =�ℎ𝑝𝑝ℎ𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟−ℎ𝑀𝑀𝑀𝑀11�𝐷𝐷 where: Vg = Vertical head gradient Hphreatic = Water elevation in the shallow aquifer = 66.61’ HMW= Water elevation in deep well MW11 = 66.85’ D = The difference in elevation between the shallow water table and the middle of the well screen in MW11 = (66.61 – 29.3) = 37.31’ Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 11 Troutman, Iredell County, North Carolina Vertical head gradient: 𝑉𝑉𝑔𝑔=66.61 −66.8537.31 = -0.0064 The head gradient suggests a value very near zero indicating that it is transition zone between a recharge and discharge area. This seems reasonable as the site is located near Lake Norman where local groundwater and surface water are discharging to. To provide preliminary estimates of hydraulic conductivity (K) and groundwater flow velocity (v) for the phreatic aquifer, Terraquest personnel performed slug tests on monitoring wells MW3, MW5, and MW7 on December 3, 2018 as part of the CSA. The preliminary hydraulic conductivity estimates range from 0.176 to 0.427 feet per day. Using an average hydraulic conductivity value of 0.336 feet/day, an average groundwater seepage velocity was determined to be 16.35 feet per year. An effective porosity of 15 percent was chosen based on published values of effective porosity for silt with the value skewed toward silty sands based on a silt range of 3-19 percent and a silty sand range of fine to silty sand of 10-28 percent (Sanders, 1998). An average hydraulic gradient as measured on December 3, 2018 across the site was used. Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 12 Troutman, Iredell County, North Carolina 2.6 Local Topography The local topography is characterized by gently rolling, well rounded hills and long low ridges with a few hundred feet of elevation difference between the hills and valleys. The majority of the surrounding 1,000 feet of the site is mapped at approximately 800-900 feet above sea level. Local topography is depicted in Figure 1. 2.7 Land Cover/Surface Drainage The release area is currently overlain by asphalt as shown below. The property slopes to the west, southwest behind the store where there are grass/gravel areas that precipitation can infiltrate the ground. Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 13 Troutman, Iredell County, North Carolina 3.0 SOIL ASSESSMENT AND EXCAVATION Through the 2017 Site Check, 2018 LSA, the 2019 UST closure, the 2019 over-excavation, and the CSA, a total of fifty-seven samples were collected to delineate the extent of soil contamination. The area of STG MSCC violation is generally centered on the UST basin with a smaller area around the northern dispenser island. The volume of contamination is a sum of these two areas. With an average depth to water of 31 feet in monitoring wells near the UST basin in April 2019, the calculated tonnage at the site includes 1,220 tons near the basin and 15 tons at the northern dispenser area. The area is shown here: Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 14 Troutman, Iredell County, North Carolina Note that Terraquest had discussions with the NCDWM-UST in 2019 prior to and during the UST closure regarding further excavation of contaminated soil as it was exposed and readily available to dig out. Ultimately, the Trust Fund did not authorize additional excavation. The RP chose to dig out an additional 94.66 tons in the southwest direction from the UST basin as it extended away in the direction where over six feet of product has been gauged. The limits of excavation in the sloping direction of product flow were all still above the STG MSCCs including some material that could have been excavated that was above the Residential MSCCs. Again, Terraquest’s request to dig this material out was denied. 4.0 FREE PRODUCT ASSESSMENT AND RECOVERY Discovery Prior to developing monitoring wells MW2 – MW4 on June 19, 2018, monitoring wells were visually checked for the presence of free product with a bailer prior to their development. At that time, free product was observed in monitoring well MW2. Product was subsequently discovered in monitoring well MW16 on September 23, 2020, monitoring well MW17 on March 22, 2021, and in soil vapor extraction (SVE) well SVE3 on November 22, 2021.

Recovery events MMPE events have been conducted for this release incident as authorized on ePATAs 40784-002, -007, and -013. All the events were five days in length. MMPE services were provided by Zava Industrial, Inc. for the October 2018 event and by EarthX, Inc. for the April 2019 and March 2021 events. The October 2018 event was successful in removing 4,041 gallons of liquid, the April 2019 event recovered 3,461 gallons, and the March 2021 event recovered 4,679 gallons. Emissions of 56.86 gallons, 64.23 gallons, and 20.72 gallons were reported for the three events, respectively. Additional MMPE events were denied by the NCDWM-UST. Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 18 Troutman, Iredell County, North Carolina Free product delineation Following a high-resolution study conducted in June 2020 by Dakota Technologies Company, LLC, additional monitoring wells MW15, MW16, and MW17 were installed by an NC-licensed driller on September 22-23, 2020 at previously selected locations validated by the high-res data. Their locations around MW2 are shown on the enclosed Figure 3. Table 4 shows well construction details. The screen intervals were extended above the water table on all three wells to capture the product at shallower depths in accordance with typical well construction policy. The high-resolution study identified higher concentrations within the analyzed area as follows: Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 19 Troutman, Iredell County, North Carolina Product locations and water table fluctuations As apparent from water table fluctuations and data from the high resolution study, several areas of free product are present vertically at the site. Greater product thicknesses were noted when the water table is lower. The majority of free-phase product is located 30 to 40 feet BGL.

Personnel bailed product from an initial thickness of 4.12 feet at static conditions to a thickness of 0.25 feet that repeatedly showed up through several bails. As product was bailed from the well, it was temporarily placed into a 5-gallon bucket at the well. When that bucket filled, the contents were transferred to a transport can during which time the well would fill back up with 6-8" of product. Complete removal of the product was not possible. In total, over six gallons of product were removed through the efforts and later disposed of offsite in an environmentally-sound manner. In summary, those efforts amount to a six-gallon recovery via hand bailing in half an hour. Following the half-hour of bailing, the rate of return was recorded for two hours following the bailing as detailed in tabular and graphical form: Time Top of Casing Elevation (feet) Depth to Product from Top of Casing (feet) Depth to Water from Top of Casing (feet) Free Product Thickness (feet) Groundwater Elevation (feet)Comments Type II Groundwater Monitoring Well 9:15:00 AM 97.83 28.58 32.70 4.12 68.14 9:45:00 AM 97.83 29.83 30.08 0.25 67.93 9:50:00 AM 97.83 29.69 30.00 0.31 68.06 9:55:00 AM 97.83 29.65 30.00 0.35 68.09 10:00:00 AM 97.83 29.66 30.05 0.39 68.06 10:05:00 AM 97.83 29.63 30.02 0.39 68.09 10:10:00 AM 97.83 29.60 29.97 0.37 68.13 10:15:00 AM 97.83 29.58 29.95 0.37 68.15 10:20:00 AM 97.83 29.55 29.94 0.39 68.17 10:25:00 AM 97.83 29.55 29.94 0.39 68.17 10:30:00 AM 97.83 29.55 29.95 0.40 68.17 10:35:00 AM 97.83 29.55 29.94 0.39 68.17 10:40:00 AM 97.83 29.55 29.95 0.40 68.17 10:45:00 AM 97.83 29.55 29.95 0.40 68.17 10:50:00 AM 97.83 29.55 29.94 0.39 68.17 10:55:00 AM 97.83 29.54 29.95 0.41 68.18 11:00:00 AM 97.83 29.54 29.95 0.41 68.18 11:05:00 AM 97.83 29.53 29.94 0.41 68.19 11:10:00 AM 97.83 29.52 29.94 0.42 68.20 11:15:00 AM 97.83 29.52 29.93 0.41 68.20 11:20:00 AM 97.83 29.51 29.93 0.42 68.21 11:25:00 AM 97.83 29.50 29.92 0.42 68.22 11:30:00 AM 97.83 29.50 29.92 0.42 68.22 11:35:00 AM 97.83 29.50 29.92 0.42 68.22 11:40:00 AM 97.83 29.49 29.92 0.43 68.22 11:45:00 AM 97.83 29.48 29.91 0.43 68.23 11:50:00 AM 97.83 29.48 29.90 0.42 68.24 11:55:00 AM 97.83 29.48 29.90 0.42 68.24 12:00:00 PM 97.83 29.48 29.90 0.42 68.24 Product removed from well with disposable bailer for half an hour.

Those wells include sixteen Type II wells and one Type III telescoping deep well. The well locations are shown on Figure 3, their construction is detailed on Table 4. Groundwater Sampling The latest groundwater monitoring event was conducted on January 18, 2023 when Terraquest personnel attempted to sample monitoring wells MW1-17 and water supply wells WSW1, WSW2, and WSW4. Note that new gravel had been placed over monitoring well MW12, so field personnel had to return with a metal detector and locate and sample the well on January 20, 2023. Monitoring wells MW2, 3, MW15, MW16, and MW17 contained free product and were not sampled. Access agreements were sent to all water supply well owners prior to entry onto their property. The owner at water supply well WSW3 did not allow sampling of that well. Monitoring and supply wells were sampled by Terraquest field personnel as detailed in Appendix A. The retrieved samples were placed on ice pending transit to an NC-certified laboratory for analysis. All wells were sampled for 6200B targeting VOCs found in the subject contaminant, gasoline. The analytical results of the sampling events reveal an oval-shaped plume that extends from beyond monitoring well MW12 to the south, between monitoring wells MW4 and MW7 to the north, to the west of monitoring well MW10, and to the east of monitoring well MW6 beneath Perth Road. The 2L Standard violation plume, applicable to this High Risk site, measures 170 feet long by 110 feet across at the widest point and covers an area of 13,700 square feet and is approximately the same size and shape as when last sampled in May 2022. The GCL violation Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 22 Troutman, Iredell County, North Carolina plume covers an area of 4,300 square feet and the extent of product is estimated at 1,000 square feet. The analytical results are summarized on Table 5 and on Figure 5. Further details of the results follow: Free product: MW2 (4.43’), MW3 (0.3’), MW15 (0.35’), MW16 (4.78’), MW17 (MW17: meter had trouble reading thickness. Product presence was confirmed with bailer.) >GCL: MW5, MW6 > 2L Standards: MW1, MW4, MW8, MW10-13 <2L Standards: MW7, MW9, MW14 Historical groundwater analytical data is summarized in Appendix C. The full analytical report for the recent event is provided in Appendix D. The vertical extent of groundwater contamination was estimated based upon the concentrations noted in the Type III (MW11) groundwater monitoring well. Petroleum-type compounds were reported above the 2L Groundwater Standards in the deep well that is screened from 65-70 feet BGL. The estimated vertical extent of 2L Standard violations in groundwater is approximately 80 feet BGL. 6.0 CONCLUSIONS A groundwater sampling event conducted on January 18, 2023 for the Perth Mini Mart release incident reveals the continued presence of over four feet of free-phase product, GCL violations, and 2L Standard violations. The site is ranked a High Risk based on the presence of nineteen sole- source active water supply wells located within 1,000 feet of the incident. Groundwater Monitoring Report (1/18/23 event) Madhukunj, LLC Terraquest Environmental Consultants, P.C. #40784 Perth Mini Mart Prepared: 2/7/23 23 Troutman, Iredell County, North Carolina As the NCDWM-UST has previously approved a Corrective Action Plan Feasibility Study and Corrective Action Design Report that details a sparge and vent treatment system, Terraquest recommends the preparation of a Record of Decision to implement active remediation. Semi- annual groundwater monitoring should continue until the treatment system is activated. 7.0 LIMITATIONS This report is limited to the investigation of dissolved petroleum hydrocarbons, such as gasoline, in groundwater and does not imply that other unforeseen adverse impacts to the environment are not present at or around the Perth Mini Mart property located in Troutman, Iredell County, North Carolina. In addition, subsurface heterogeneities not identified during this study may influence the migration of groundwater or contaminants in unpredicted ways. The limited amount of sampling and testing conducted during this study cannot practically reveal all subsurface heterogeneities. Furthermore, the subsurface conditions, particularly groundwater flow, elevations, and water quality may very through time. The opinions and conclusions arrived at in this report are in accordance with North Carolina Department of Environmental Quality regulations and guidelines and industry-accepted geologic and hydrogeologic practices at this time and location. No warranty is implied or intended.

APPENDIX A Page 1 of 8   TECHNICAL METHODS/STANDARD PROCEDURES    Equipment Decontamination    All soil sampling equipment utilized during site assessment activities is decontaminated according  to standard and accepted protocol.  Cleaning solutions range from clean potable water to acidic  solutions or organic solvents depending on the contaminants present at the site.  Equipment  utilized at sites, such as hand augers, contaminated with petroleum hydrocarbons, is generally  decontaminated with a low‐sudsing detergent such as Luiquinox® and triple rinsed with distilled  water.  Larger equipment, such as drill rigs and associated tools, is steam cleaned.  All  decontamination procedures are completed within an established decontamination area which is  located away from the active study area.  Frequency of equipment decontamination depends on  the nature of work being performed, but in no case is decontamination performed less frequently  than once per test (i.e., soil boring, well installation, sample collection, etc.).  Equipment blanks are  collected as a quality control measure when required by job specifications.    Soil Boring Installation    Soil borings are completed using hand‐operated sampling tools, truck‐mounted drills, or  Geoprobe® drilling rigs depending on the depth of sample collection and other site‐specific  conditions.  Hand operated stainless‐steel bucket augers are utilized to collect soil samples at  regular intervals to determine site stratigraphy and to test for the presence of volatile organic  compounds.  Samples retrieved from the hand auger are necessarily disturbed during the augering  process, but can provide accurate information on soil type and contaminant concentrations when  properly interpreted.  Soil samples from hand augered borings are generally retrieved at one to  two foot intervals.    Truck‐mounted or Geoprobe® drilling equipment is often utilized when sample retrieval depths  exceed twenty feet or subsurface conditions prevent utilization of hand augers (i.e., buried rocks,  wood, bricks or other materials occur in the subsurface).  Truck‐mounted drilling rigs usually  retrieve soil via a hollow‐stem auger/split spoon collection method.  Geoprobe® rigs usually employ  a Macro‐Core® tube retrieval system.      Hollow stem augers provide relatively undisturbed 2‐foot cores of soil samples.  Soil samples are  generally collected at five foot intervals utilizing standard penetration test procedures as defined  by the American Society for Testing and Materials (ASTM) or are pushed to the desired depth using  the head of the drill rig.  The standard penetration test involves driving a 2" outside diameter by 1‐ 3/8" inside diameter split‐spoon sampler a minimum distance of one foot with a 340‐lb. slide  hammer falling a distance of 30 inches.      A Geoprobe® rig is a hydraulically‐powered soil probing machine.  The probe utilizes static force  and percussion to advance a small diameter sampling device into the subsurface.  The sampling  apparatus provides relatively undisturbed 5‐foot cores of soil samples.  Soil samples are collected  Page 2 of 8  continuously.  The Macro‐Core® tube contains an inserted poly‐vinyl chloride (PVC) liner which  retains the soil sample as the tube is driven into the ground.  The Macro‐Core® tube is  decontaminated between each 5‐foot sample interval in a soil boring using a Liquinox and tap‐ water mixture.  A new PVC liner is used to collect soil from each sample interval in a soil boring.       Soil samples retrieved from the hollow‐stem augers or Geoprobe are then carefully described  according to the Unified Soil Classification System.  Soil descriptions are recorded on a soil  boring log.    Soil Sampling    Soils to be analyzed by a North Carolina‐certified laboratory are prepared according to the specified  analytical method.  Initially, soil samples are removed from the ground using either a hand auger,  backhoe bucket, spilt spoon auger, or a Macro‐Core® sampling tube.  During the removal, care is  taken to keep the disturbance of the soil structure to a minimum to reduce the loss of  contaminants.  Once removed, the samples are placed in the proper sample container for the  specified analytical method.  For samples collected for the MADEP VPH and EPA Method 8260, a  TerraCore® sampler is used to collect one 5‐gram allotment of soil.  The allotment is placed in  methanol‐preserved 40 mL vials.  Also, one 5‐gram allotment of soil is placed into sodium bisulfate‐ preserved 40 mL vials (one 5‐gram allotment per vial, 2 vials per sample) for the 8260 low  concentration method.  A 250‐mL glass jar of the sampled soil is also collected to provide moisture  content information.  Soils sampled for MADEP EPH, EPA Method 8270 and TPH 5030 and 3550 are  placed in a 250‐mL glass jar (for MADEP EPH analysis an amber jar is required).  TPH 5030 samples  are preserved in methanol similar to the 8260 analysis.  Field personnel wear new, disposable  nitrile gloves during the collection of each sample.     The soil samples are labeled with the sample location, sample identification, date and time of  collection, and the analytical method.  The samples are placed on ice, sent to a laboratory, and  analyzed before the expiration of an analytical method’s prescribed holding time.  Chain‐of‐custody  documentation is maintained for each sample collected in the field.    If the soil is being sampled for volatile or semi‐volatile compounds, a portion of the collected soil is  placed in a sealable bag and screened for volatile organic vapors.  Head screening procedures are  described in the following paragraph.     Headspace Screening    Collected soil samples are routinely tested for the presence of volatile organic compounds (VOCs).   After retrieval from the ground, a portion of a soil sample is placed in a sealable plastic bag.  The  soil samples are then set aside for approximately five minutes so that volatile constituents present  in the sample can reach equilibrium concentrations with headspace gases in the bag.  Once a  suitable time period has passed, the probe of the sampling instrument, typically an Organic Vapor  Monitor (OVM) or a Photo Ionization Detector (PID), is inserted into the bag and the relative  concentration of total VOCs is measured and permanently recorded in a field note book.  VOC  Page 3 of 8  concentrations are measured using either a Thermo Electron Corp. Innova Series catalytic OVM or  an Ion Science PhoCheck PID.  Both the OVM and PID instrumentation are periodically calibrated  according to the manufacturer’s recommended procedures.    The OVM and PID are qualitative tools employed to detect and estimate the concentration of  organic or hydrocarbon vapors.  A thin probe is inserted through a small break in the seal of a  bagged soil sample.  For the OVM, an air sample from the headspace of the bag is drawn through  the probe into an internal chamber where the vapors are catalyzed.  The concentration of the VOCs  is registered on a digital scale in parts per million (ppm).  For the PID, an air sample from the  headspace of the bag is drawn across the face of a lamp causing the sample to emit photons, the  presence of which are converted into a VOC ppm reading that is displayed.  Oxygen levels are field  calibrated prior to each use.  VOC calibration occurs periodically depending upon use by using a  span gas of known concentration in a process recommended by the manufacturer.      Well Installation/Construction    Monitoring wells are installed using hand‐operated sampling tools, a truck‐mounted drill rig, or a  Geoprobe drilling rig depending on the depth of well and other site‐specific conditions. All  monitoring wells are installed according to the requirements of 15A NCAC 2C‐Well Construction  Standards.  Specifically, individual monitoring wells are constructed of 2‐inch diameter, schedule 40  PVC casing riser and screen.  The screen interval is generally 10 to 15 feet of machine slotted PVC  with a slot size of 0.010".  Only flush threaded joints are used.  The annulus space around the  screen is filled with washed filter pack No. 2 sand.  The filter pack extends one to two feet above  the top of the screen.  A one to two foot‐thick bentonite pellet seal is then placed above the filter  pack.  The remainder of the well annulus is completely filled with a Portland (Type I/II) cement  grout mixture.  A protective outer steel manhole, locking cap, and concrete pad is installed for each  well.    Type II Monitoring Well Construction     Single‐cased monitoring wells are generally used in delineation of groundwater quality within the  surficial aquifer.  The wells are constructed of 2‐inch diameter, schedule 40 PVC casing and screen.   The screen interval is generally 10 to 15 feet of machine slotted PVC with a slot size of 0.010".  Only  flush threaded joints are used.  The annulus space around the screen is filled with washed filter  pack No. 2 sand.  The filter pack extends one to two feet above the top of the screen.  A one to two  foot‐thick bentonite pellet seal is then placed above the filter pack.  The remainder of the well  annulus is completely filled with a Portland (Type I/II) cement grout mixture.  A protective outer  steel manhole, locking cap, and concrete pad are installed for each well.    Type III Monitoring Well Construction    Double‐cased monitoring wells are used in the delineation of groundwater quality within a deeper  portion of the surficial aquifer or an additional aquifer (e.g. aquitard, bedrock).  A four to six‐inch  outer casing is installed through the surficial aquifer until a sufficient depth or until the deeper  Page 4 of 8  aquifer is encountered.  The casing is secured with a Portland‐grout collar that is tremmied into the  annular spaced from the bottom of the bore hole to the surface.  Once the grout has sufficiently  cured, the bore hole is continued through the bottom of the outer casing to a depth approximately  15 ‐ 20 feet beneath the outer casing.  The inner casing is constructed of 2‐inch diameter, schedule  40 PVC casing riser and screen.  The screen interval is generally 5 to 10 feet of machine slotted PVC  with a slot size of 0.010".  Only flush threaded joints are used.  The annulus space around the  screen is filled with washed filter pack No. 2 sand.  The filter pack extends one to two feet above  the top of the screen.  A one to two foot‐thick bentonite pellet seal is then placed above the filter  pack.  The remainder of the well annulus is completely filled with the same Portland grout mixture  used in the outer casing.  A protective outer steel manhole, locking cap, and concrete pad are  installed for each well.    Well Development    Following installation of each well, surging and pumping or bailing techniques will be used to  remove fines from the screened interval.  Groundwater is removed from each well until clear water  is retrieved or a noticeable reduction in the amount of silt is achieved.  Purged groundwater is  disposed of in an environmentally safe manner.    Groundwater Sampling    Petroleum Sites    Groundwater samples are collected from temporary or permanent monitoring wells according to  established sampling protocol.  When multiple monitoring wells or sampling points are sampled,  sampling is completed beginning with the least contaminated well to the most contaminated well,  if it is known.  When permanent monitoring wells for petroleum sites are sampled, the well is  purged of a minimum of three well‐bore volumes prior to sample collection in order to assure that  sampled water is representative of aquifer conditions.  In temporary wells, the first water which  migrates into the open borehole is sampled.  Samples from both temporary and permanent  monitoring wells are collected using individually wrapped disposable polyethylene bailers by field  personnel wearing disposable nitrile gloves.  Only one well is sampled with a given bailer in order to  prevent sample cross‐contamination.  During both well purging and sampling, proper protective  clothing and equipment is used and is dependent upon the type and level of contaminants present.  Also, field personnel change gloves between different samples to reduce the chance of cross‐ contamination. Water samples are transferred from the bailer to laboratory‐prepared sampling  containers using slow emptying devices to reduce the chance of contamination loss through  volatilization.  Preservatives, such as acids, are provided by the laboratory in pre‐prepared  containers in which collected samples are placed if in‐field preservation is necessary.  The samples  are labeled with the project name, project number, sample identification, required analysis, and  date and time of collection.  The samples are placed on ice, shipped to a certified laboratory, and  analyzed before the expiration of an analytical method’s prescribed holding time.  Chain‐of‐custody  documentation is maintained for each sample collected in the field.      Page 5 of 8    Other Groundwater Sampling Protocols    When required by state or federal regulations, low‐flow groundwater sampling procedures are  instituted.  Groundwater samples collected in low‐flow situations are collected using a peristaltic  pump. A peristaltic pump is a type of positive displacement pump. The fluid is contained within a  flexible tube fitted inside a circular pump casing.  A rotor with a number of rollers attached to the  external circumference compresses the flexible tube. As the rotor turns, the part of tube under  compression closes thus forcing the fluid to be pumped to move through the tube.  Groundwater  parameters such as water level drawdown, pH, conductivity, dissolved oxygen (DO) and turbidity.  Pumping rate, drawdown, and the time or volume required to obtain stabilization of parameter  readings can be used as a future guide to purge the well. Measurements are collected at a pre‐ pumping established interval (typically five to ten minutes). Once all or a majority of the  parameters have stabilized for three successive readings, stabilization has been achieved. In lieu of  measuring all five parameters, a minimum subset would include pH, conductivity, and turbidity or  DO. Three successive readings should be within ± 0.1 for pH, ± 3% for conductivity, and ± 10% for  turbidity and DO.     Upon parameter stabilization, sampling is initiated. Sampling flow rate is maintained at the estab‐ lished purge rate or is adjusted slightly to minimize aeration, bubble formation, turbulent filling of  sample bottles, or loss of volatiles due to extended residence time in tubing. The same device used  for purging is used to collect the groundwater sample. Generally, volatile parameters are sampled  first. The sequence in which samples for inorganic parameters are collected is not determined  unless filtered (dissolved) samples are collected. Preservatives, such as acids, are provided by the  laboratory in pre‐prepared containers in which collected samples are placed if in‐field preservation  is necessary.  The samples are labeled with the project name, project number, sample  identification, required analysis, and date and time of collection.  The samples are placed on ice,  shipped to a certified laboratory, and analyzed before the expiration of an analytical method’s  prescribed holding time.  Chain‐of‐custody documentation is maintained for each sample collected  in the field.      During both well purging and sampling, proper protective clothing and equipment is used and is  dependent upon the type and level of contaminants present.   Also, field personnel change gloves  between different monitoring wells or sampling points to reduce the chance of cross‐ contamination.  When multiple monitoring wells or sampling points are sampled, sampling is  completed beginning with the least contaminated well to the most contaminated well, if it is  known.    Stockpile Sampling    The number of composite samples collected from a stockpile or a total quantity of excavated soil is  based upon the cubic yardage.  One composite sample is collected for every 100 cubic yards of  contaminated soil excavated.  The volume of a stockpile or total quantity of excavated soil is  calculated by approximating the general geometry of a stockpile or estimating the capacity of the  Page 6 of 8  dump trucks used for hauling.  If a stockpile is sampled, a grid pattern is laid out on the stockpile,  dividing the stockpile into segments of approximately 200 cubic yards.  Two soil borings are  advanced within a grid and three soil samples are collected from each soil boring at various depths.   The six soil samples are mixed into a composite sample by a trained TerraQuest technician.  If truck  loads are sampled, an aliquot sample is collected from the hauling trucks at a frequency based  upon the capacity of the hauling trucks.      Aliquots are gently mixed into a composite sample by a trained TerraQuest technician. Every effort  is made to minimize the loss of contaminants through volatilization.  The composited soil samples  are jarred in the appropriate laboratory‐prepared containers, labeled with the sample location,  sample identification, date of collection, time of collection, the analytical method, and the  preservative.  The samples are placed on ice, shipped to a laboratory, and analyzed before the  expiration of an analytical method’s prescribed holding time.  Chain‐of‐custody documentation is  maintained for each sample collected in the field.    Surface Water Sampling    Surface water samples, specifically samples from creeks or streams, are collected from a  moving/flowing portion of the creek or stream to ensure that stagnant water is not collected.  Field  personnel are careful to collect samples from flowing areas that are not so turbulent as to cause a  loss of volatile contaminants which might have been contained in the creek’s/stream’s water.   Samples are collected by field personnel wearing disposable nitrile gloves.  Field personnel change  gloves between different locations to reduce the chance of cross‐contamination.  Samples are  collected directly from the appropriate creek or stream location and placed into the appropriate  laboratory‐prepared containers.  Preservatives, such as acids, are provided by the laboratory in pre‐ prepared containers in which collected samples are placed if in‐field preservation is necessary. The  samples are labeled with the project name, project number, sample identification, required  analysis, and date and time of collection.  The samples are cooled on ice to approximately four  degrees centigrade, shipped to a certified laboratory, and analyzed before the expiration of an  analytical method’s prescribed holding time.  Chain‐of‐custody documentation is maintained for  each sample collected in the field.       Potable Well Sampling    Groundwater samples from potable wells are collected from sampling points, typically spigots,  located in the closest proximity to the potable well pump house as possible.  Prior to sample  collection, the water is run for a sufficient amount of time to purge the bladder tank and assure  that sampled water is representative of aquifer conditions.  Once purged, the flow rate is reduced  and samples are placed in the appropriate laboratory prepared containers with the appropriate  acid preservatives added if preservation of the sample is necessary.  The samples are labeled with  the project name, project number, sample identification, required analysis, and date and time of  collection.  The samples are placed on ice, shipped to a laboratory, and analyzed before the  expiration of an analytical method’s prescribed holding time.  Chain‐of‐custody documentation is  maintained for each sample collected in the field.   Page 7 of 8  Public Water Supply Line Sampling    Groundwater samples from public water supply lines are collected from sampling points, typically  spigots.  To sample the spigot, the flow rate is reduced and samples are placed in the appropriate  laboratory prepared containers.  The samples are labeled with the sample location, sample  identification, date of collection, time of collection, and required analytical method.  The samples  are placed on ice, shipped to a laboratory, and analyzed before the expiration of an analytical  method’s prescribed holding time.  Chain‐of‐custody documentation is maintained for each sample  collected in the field.     Air Sampling    Air samples are collected with the aide of a manually operated MityVac® pump manufactured by  Pristech, Inc.  The air sampling process begins by connecting a length of rubber hose from the  MityVac® pump to the port to be sampled, or by hanging the hose inside of an emissions stack in  such a manner as to ensure no outside air causes dilution.  Another length of hose is fixed to the  outlet port of the pump and is connected to a new Tedlar bag.  Once the pump is hooked up, a  valve on the Tedlar collection bag is opened and air is manually forced into the bag by the pumping  action of sampling personnel.      Field Measurements    Field measurements taken to determine the pH, conductivity, temperature, and dissolved oxygen  concentration of a particular groundwater sample are taken directly after a particular monitoring  well has been adequately purged.  This ensures that the groundwater parameter data collected is  representative of the aquifer conditions at a given location.  Once purging of the monitoring well is  complete, the decontaminated probe head and cord of the appropriate unit is lowered into the  required monitoring well.  If the depth to water in a specific monitoring well is greater than the  length of cord for a particular unit, a new, disposable bailer is slowly lowered into the appropriate  monitoring well and a representative groundwater sample is retrieved.  A slow pouring device is  fitted onto the end of the disposable bailer and the sample is slowly poured into a new, disposable  plastic cup.  Groundwater parameter data are then collected from the groundwater in the cup  using the required unit.      For pH, conductivity, and temperature, a Hanna Instruments Model 991300 portable meter is  utilized.  This unit is periodically calibrated and maintained in accordance with the unit’s operations  manual by field personnel.  Prior to data collection, the unit is properly decontaminated to prevent  cross‐contamination.  The unit is decontaminated between each sample.  The procedure used for  sample measurement involves lowering the meter’s probe into the new, disposable cup containing  the groundwater sample to be measured and slowly stirring the probe to force groundwater across  the probe’s membrane.  The measurements displayed by the meter are then recorded.      For dissolved oxygen concentration measurements, a YSI® Model 55 Handheld Dissolved Oxygen  System is utilized.  This unit is periodically calibrated and maintained in accordance with the unit’s  Page 8 of 8  operations manual by field personnel.  Prior to data collection, the unit is properly decontaminated  to prevent cross‐contamination.  The unit is decontaminated between each sample.  The procedure  used for sample measurement involves adjusting the unit for the correct altitude where the  sampling will take place and adjusting the reported units desired.  Once this is done, the unit’s  probe is inserted into the groundwater sample to be measured and the probe is slowly stirred to  force the groundwater across the probe’s membrane.  The measurements displayed by the unit are  then recorded.      For turbidity measurements, a Hach 2100P Portable Turbidity meter or equal equivalent is utilized.   The unit is calibrated prior to use in accordance with the unit’s operations manual by field  personnel.  Groundwater samples are collected in glass containers for measurement by the  instrument.  The glass containers are washed with bottled‐water between each measurement  collection.  Once the sample is collected and inserted into the instrument, the measurements  displayed by the instrument are then recorded.          APPENDIX B Perth Mini Mart (#40784) Chronological Site History Terraquest Environmental Consultants, P.C. Page 1 of 4 CHRONOLOGICAL SITE HISTORY Perth Mini Mart 818 Perth Road, Troutman, NC Facility ID#: 00-0-0000024524 NCDWM UST Incident No.: 40784 Terraquest Project No.: 08217 March 4, 1980 According to the North Carolina UST Database Records, two 6,000- gallon gasoline, one 4,000-gallon gasoline, and one 2,000-gallon diesel USTs were installed at the site. November 16, 2017 Terraquest personnel mobilized to the Perth Mini Mart facility to conduct a limited scope site check. The UST owner had recently noted inventory record discrepancies based upon ATG reading for UST T3. To investigate these irregularities, the UST owner had a tank tightness test completed on this UST which resulted in failure. In response, the UST owner submitted an UST-17A UST Suspected Release 24-Hour Notice Form. A site check was then required to investigate a potential release of petroleum. Soil quality was assessed through the advancement of four soil borings (B1 – B4) around the suspect UST. Samples from the B1(18-20), B2(8- 10), B3(8-10), and B4(13-15) were submitted for laboratory analysis per EPA Method 8015 utilizing the 5030-extraction method for gasoline range organics (GRO). Analytical results of the collected soil samples revealed detectable concentrations of TPH GRO in each sample; however, only the B1(18-20) sample contained a TPH GRO concentration (497 ug/kg) above the 100 mg/kg action limit. December 8, 2017 Terraquest submitted a copy of the Site Check Report Letter and UST- 61 24 Hour Release Reporting Form were submitted to the NCDWM- UST. Three soil samples were collected from the MW1 soil boring at the 10-12 ft. BGL, 20-22 ft. BGL, and 30-32 ft. BGL intervals. December 19, 2017 The NCDWM-UST issued an NORR that confirmed receipt of the Site Check Report and requested the completion of an LSA. January 16, 2018 Terraquest personnel supervised the installation of one Type II groundwater monitoring well (MW1) as part of a Phase I LSA in the vicinity of the previous B1 soil boring. Perth Mini Mart (#40784) Chronological Site History Terraquest Environmental Consultants, P.C. Page 2 of 4 January 22, 2018 Terraquest personnel collected a groundwater sample from monitoring well MW1 after gauging the well for free product using an oil/water interface probe that did not detect any measurable amount of free product. Prior to groundwater sample collection, Terraquest gauged 6.25 feet of free product in monitoring well MW2. No additional wells contained free product on this date. Groundwater samples were collected from monitoring wells MW3 and MW4. March 19, 2018 The NCDWM-UST LUST Trust Fund issued a correspondence regarding the Commercial State Trust Fund Eligibility Application. The release incident was found conditionally eligible following a $20,000 deductible that was noted as having been met. June 18-19, 2018 Terraquest personnel supervised the installation of three additional monitoring wells (MW2 – MW4) as part of the Phase II LSA. August 3, 2018 Terraquest submitted an LSA Report (Phase I & II) to the NCDWM-UST. August 6, 2018 Terraquest requested pre-approval of costs necessary to complete a CSA. September 6, 2018 Terraquest requested pre-approval of costs necessary to conduct free product recovery via MMPE. September 11, 2018 The NCDWM-UST grants pre-approval of costs for free product recovery via MMPE. October 3, 2018 The NCWM-UST grants pre-approval of costs for CSA activities. October 22-26, 2018 Terraquest supervised an MMPE event at the site. A total of 4, 041 gallons of a free product/contaminated groundwater mixture were recovered. Emissions stack calculations indicate the exhaust of 56.86 gallons of petroleum. November 26-28, 2018 Terraquest personnel supervised the installation of groundwater monitoring wells MW5-MW11. These wells were installed as part of the CSA. Monitoring wells MW5-MW10 are Type II wells installed for horizontal assessment while monitoring well MW11 is a Type III well installed for vertical delineation of contamination. Soil borings December 3, 2018 As part of the CSA, Terraquest personnel sampled monitoring wells MW1 – MW11 and surveyed the casing elevations of recently installed Perth Mini Mart (#40784) Chronological Site History Terraquest Environmental Consultants, P.C. Page 3 of 4 wells MW5-MW11. Slug tests were conducted on monitoring wells MW3, MW5, and MW7. April 22-26, 2019 Terraquest supervised an MMPE event at the site. Free product was removed from monitoring well MW2. A total of 3,461 gallons of contaminated groundwater was removed. Emissions stack calculations indicate the exhaust of 64.23 gallons of petroleum. October 7-11, 2019 Terraquest supervised an MMPE event at the site. Free product was removed from monitoring well MW2. A total of 3,027 gallons of contaminated groundwater was removed. Emissions stack calculations indicate the exhaust of 20.57 gallons of petroleum. June 1, 2, and 3, 2020 Terraquest supervised a high-resolution study conducted by Dakota Technologies Company, LLC. The study was requested by the NCDWM- UST to identify the location of free product and involved the advancement of ten borings that were analyzed using an Ultra-Violet Optical Screening Tool (UVOST). September 22-23, 2020 Terraquest supervised the installation of three free product monitoring wells, MW15, MW16, and MW17. A free product evaluation was performed on monitoring well MW2. Groundwater monitoring wells without free product were sampled and sent off for VOC analysis. While there were no indications of a release from the diesel AST, STF demanded that 625 analysis be performed on all wells at the site at a cost exceeding $3,000 to rule out a release. March 22-26, 2021 Terraquest supervised an MMPE event at the site. Free product was removed from monitoring wells MW2, MW16, and MW17. A total of 4,679 gallons of contaminated groundwater was removed. Emissions stack calculations indicate the exhaust of 20.72 gallons of petroleum. April 21, 2021 Terraquest personnel gauged monitoring wells and found free product in MW16 (1.49’) and MW17 (0.05’). November 16-17, 2021 Terraquest supervised the installation of pilot test wells SVE1, SVE2, SVE3, and AS1. November 22-23, 2021 Terraquest conducted SVE and air sparge pilot tests. January 17, 2022 Terraquest submitted a Corrective Action Plan Feasibility Study to the NCDWM-UST. Perth Mini Mart (#40784) Chronological Site History Terraquest Environmental Consultants, P.C. Page 4 of 4 February 23, 2022 The NCDWM-UST approved the CAP Feasibility Study. May 9 & June 1, 2022 Terraquest sampled groundwater monitoring wells associated with the release incident to provide updated information for the CAP Design Report. August 23, 2022 Terraquest submitted a Corrective Action Design Report to the NCDWM-UST. November 1, 2022 The NCDWM-UST issued an NORR requesting the completion of a groundwater sampling event. December 5, 2022 Terraquest requested an extension of the December 31, 2022 deadline for the submittal of a monitoring report. December 7, 2022 The NCDWM-UST granted an extension to the submittal deadline for the Monitoring Report. The new submittal deadline is February 23, 2023. January 18, 2023 Terraquest sampled all of monitoring wells MW1-17 that did not contain free product. Free product thickness was recorded where encountered. Monitoring well MW12 was covered in new gravel and could not be located. Water supply wells WSW1, WSW2, and WSW4 were also sampled. The property owner for water supply well WSW3 did not grant permission to sample their well. January 20, 2023 Terraquest returned to site and located monitoring well MW12 using a metal detector. The well was purged and sampled.

Unless otherwise noted below, the samples arrived in good condition, and, where required, properly preserved and on ice. The temperatures of the 2 coolers at receipt time were 0.0°C and 0.7°C GC/MS VOA Method SM6200_B: The following sample was diluted to bring the concentration of target analytes within the calibration range: MW12 (400-232072-1). Elevated reporting limits (RLs) are provided. Method SM6200_B: The laboratory control sample (LCS) for analytical batch 400-609802 recovered outside control limits for the following analytes: Bromochloromethane, Bromomethane, Trichloroethene, Trichlorofluoromethane and Vinyl chloride. These analytes were biased high in the LCS and were not detected or not reported in the associated samples; therefore, the data have been reported. Method SM6200_B: The following samples were diluted to bring the concentration of target analytes within the calibration range: MW1 (400-232047-1), MW4 (400-232047-2), MW5 (400-232047-3), MW6 (400-232047-4), MW11 (400-232047-9) and MW13 (400-232047-10). Elevated reporting limits (RLs) are provided. No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page. GC Semi VOA Method 504.1: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 400-610674.
