(Terraquest) has prepared this Initial Abatement Action Report for the former BCA property located at 280 Ervin Woods Dr. in Kannapolis in Rowan County, North Carolina (herein referred to as the subject property). The release incident is associated with a 280-gallon steel non-commercial, non-regulated heating oil underground storage tank (UST) that was formerly located on the subject property off the west side of the garage building. This report documents the UST removal and soil excavation activities conducted in July and August 2023. The location of the subject property is depicted in Figure 1. The site layout is depicted in Figure 2. Environmental acronyms used in this report are detailed in Appendix A along with Terraquest’s technical methods and standard procedures. 2.0 SITE HISTORY According to the Rowan County Tax Records, the garage structure on the subject property was built in 1988. The heating oil UST was installed during the construction of the garage building and formerly supplied the building’s furnace. The garage building is heated with portable heaters. A 6,600-gallon waste oil UST was also located south of the mobile office building. The product type, capacity, date installed, date closed, and release detection information for the UST are listed in Table 1. The locations of the USTs are depicted in Figure 2. The subject property is located outside the city limits of Kannapolis, NC. Historically the subject property has been woods and a residence. Surrounding properties have historically been cultivated farmland and woods with a gradual development of residences and light industrial buildings to the, north, east, and west and a sand rock pit to the south. A water supply well is Initial Abatement Action Report – Heating Oil UST Former BCA Property Mgmt., LLC Terraquest Environmental Consultants, P.C. 280 Ervin Woods Dr. Prepared on: September 14, 2023 2 Kannapolis, NC connected to the subject property’s buildings. Each building has its own septic system that are located on the adjacent properties to the east and west. 3.0 RELEASE INCIDENT DISCOVERY On March 30, 2023, Terraquest personnel located the UST basin based upon the presence of the fill and vent port off the west side of the garage building. Terraquest advanced two soil borings, SB1 and SB2, along the south and west sides of the UST. Each boring was advanced to a depth of 15 feet below ground level (BGL). In each soil boring, soils from the sample intervals (3-5, 5-7, 8-10, and 13-15 feet BGL) were placed in sealable plastic bags and screened for volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) utilizing a Photoionization Detector (PID). The soil lithology encountered during the soil borings was a yellowish-orange, med. stiff Lean Clay (CL) from 0.5 feet to 10 feet BGL and a yellowish-orange hard Lean Clay (CL) from 10 feet BGL to 15 feet BGL. The soil samples collected for analysis were placed in the proper laboratory-prepared sampling containers, labeled with the project name, project number, sample identification, required analysis, and date and time of collection. The samples were immediately placed on ice and analyzed before the expiration of an analytical method’s prescribed holding time. The soil samples were analyzed for total petroleum hydrocarbons (TPH) for low boiling point petroleum hydrocarbons (GRO) and medium to high boiling point petroleum hydrocarbons (DRO) by UVF Trilogy technology. The North Carolina Department of Environmental Quality Division of Waste Management – UST Section (NCDEQ DWM-UST) Action Limits of 100 milligrams per kilogram (mg/kg) for TPH DRO and 50 mg/kg for TPH GRO were exceeded in the SB1 (13-13.5), SB2 (10-12), and SB2 (13-15) samples. The attached Table 2 summarizes the sample depth and detected concentrations of the SB1 and SB2 soil samples. The locations of the SB1 and SB2 soil samples are depicted in the attached Figure 3. The release incident was reported to the NCDEQ on May 9, 2023. Initial Abatement Action Report – Heating Oil UST Former BCA Property Mgmt., LLC Terraquest Environmental Consultants, P.C. 280 Ervin Woods Dr. Prepared on: September 14, 2023 3 Kannapolis, NC 4.0 UST REMOVAL AND SOIL EXCAVATION On July 31, 2023, Terraquest supervised the removal of approximately 155 gallons of heating oil from the UST by Clean Green of Durham, NC. The 280-gallon heating oil tank was buried approximately 16 inches below ground level (BGL) and was excavated and taken offsite for environmentally-sound disposal at Foss Metal recycling in Mebane, NC. The dimensions of the UST were 36 inches wide by 62 inches long. Following the UST removal, Terraquest inspected the UST and noted numerous holes up to 1.0-inch in size along the sides and seams. The tank’s former location is shown in Figure 2. A copy of the liquid waste manifest is included in Appendix B. Excavation of Contaminated Soil On July 31 and August 1, 2023, Terraquest supervised the excavation of impacted soils beneath the heating oil UST. The soil excavation continued until either the odor and/or staining dissipated, a maximum soil excavation was reached, or the foundation of the garage was in close proximity to the limits of the excavation (sidewall H.O. SW3). Soils in the sidewalls and base of the excavation were screened with a PID. Terraquest personnel identified the soil lithologies in the UST basin to be a sandy lean clay from the ground surface to approximately 10 feet BGL, a sandy silt from 10 feet BGL to 12 feet BGL, and a silty sand from 12 to 17 feet BGL. The final limits of the excavation measured 8 feet at the widest section, 12 feet at the longest section, and 17 feet in depth. A total of 74.35 tons of contaminated soil were excavated from the heating oil UST basin and hauled offsite for disposal at the Environmental Soils, Inc. soil disposal facility in Lattimore, NC. Copies of the soil disposal waste manifests are included in Appendix B. Confirmation soil samples were collected at the final limits of the soil excavation to determine in-situ soil quality along the sidewalls {H.O.SW1(7-8), H.O. SW2(7-8), H.O. SW3(7-8), and H.O. SW4(7-8)} and base of the excavation {H.O. BE1 (17) and H.O. BE2(17)}. The sidewall soil sample Initial Abatement Action Report – Heating Oil UST Former BCA Property Mgmt., LLC Terraquest Environmental Consultants, P.C. 280 Ervin Woods Dr. Prepared on: September 14, 2023 4 Kannapolis, NC depths were collected halfway down the sidewalls or where petroleum contamination was noted to document soil quality. The excavation was backfilled with clean fill dirt from a nearby soil pit. Table 3 lists the sample depths and analytical results of the final limit of excavation soil samples. The locations of the limit of excavation soil samples are depicted in Figure 3. The methods and standard procedures followed during the soil sampling are detailed in Section 4.0. Pictures of the soil excavation are included in Appendix C. 4.0 FIELD AND LABORATORY ANALYSES 4.1 Soil Sampling Methodology and Results – Soil Excavation After the soil excavation was completed on July 31 and August 1, 2023, soil samples were collected at the limits of the final excavation {H.O. SW1(7-8), H.O. SW2(7-8), H.O. SW3(7-8), H.O. SW4(7-8), H.O. BE1 (17) and H.O. BE2(17)}. All of the UST confirmation soil samples were collected following the proper soil sampling protocol in accordance with the NCDEQ DWM-UST guidelines. The final limits of the soil excavation soil samples were collected using a track excavator bucket. A grab sample from each sample location was collected, placed in the appropriate laboratory-prepared containers, and labeled with the sample identification, sample analytical method, and sample time. Since the 280-gallon UST formerly contained heating oil, the final sidewall and base of the excavation samples were analyzed for TPH (GRO) and TPH DRO by UVF Trilogy technology in the field during the soil excavation. A trip blank sample did not accompany the soil samples to the laboratory since the soil samples were in the custody of Terraquest from sample collection to the completion of the analysis. Chain-of-custody documentation was maintained for the soil samples. The analytical results of the H.O. BE1 (17) soil sample revealed concentrations greater than the TPH GRO and DRO Action Limits. Since the TPH GRO and DRO Action Limits were exceeded, the H.O BE1 (17) and H.O. BE1 (17) were submitted to a laboratory for analysis by the Risk-Based Initial Abatement Action Report – Heating Oil UST Former BCA Property Mgmt., LLC Terraquest Environmental Consultants, P.C. 280 Ervin Woods Dr. Prepared on: September 14, 2023 5 Kannapolis, NC Corrective Action (RBCA) methods EPA 8270 Base Neutrals and Acid Extractables (BNA) and Massachusetts Department of Environmental Protection (MADEP) Extractable Petroleum Hydrocarbons (EPH) targeting semi-volatile organics and EPA 8260 + methyl tert-butyl ether (MTBE) + di-isopropyl ether (IPE) and MADEP Volatile Petroleum Hydrocarbons (VPH) targeting volatile organics. The Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCCs) were exceeded for the C9-C22 Aromatic Compound in the H.O. BE1 (17) and H.O. BE2 (17) samples. The Residential MSCCs were exceeded for the C9-C18 Aliphatic Compound in the H.O. BE1 (17) sample. The analytical results of the confirmation soil samples are detailed in Table 3. Figure 3 depicts the locations of the SW and BE1 soil samples. The analytical reports for the SW and BE1 soil samples are contained in Appendix D. 4.2 Groundwater Sampling Methodology and Results – Soil Excavation Groundwater was not encountered during either soil excavation. 5.0 FREE PRODUCT No free product in the form of heating oil was observed in the bottom of the initial or final excavations. 6.0 POTENTIAL SOURCES OF PETROLEUM HYDROCARBONS The primary source of petroleum hydrocarbons in the site vicinity is the former 280-gallon heating oil UST. As previously mentioned, a 6,600-gallon waste oil UST was located south of the mobile office building. A release incident was also discovered during its removal. Approximately 18.12 tons of contaminated soil were removed from surrounding the waste oil UST. Given the distance between the two USTs and the removal of all the contaminated soil surrounding the waste oil UST, the two contaminant plumes have not comingled. Initial Abatement Action Report – Heating Oil UST Former BCA Property Mgmt., LLC Terraquest Environmental Consultants, P.C. 280 Ervin Woods Dr. Prepared on: September 14, 2023 6 Kannapolis, NC 7.0 NATURE AND ESTIMATED QUANTITY OF RELEASE The nature of the release is heating oil from the former UST. The amount of the release is currently unknown. 8.0 SITE AND VICINITY DESCRIPTION Land use in the immediate vicinity of the subject property is commercial with the subject property being a landscaping company office and maintenance yard. The subject and surrounding properties derive their drinking water from water supply wells. The garage and mobile office building’s water supply well is located 245 feet to the northeast. The adjacent property to the west at 272 Ervin Woods Dr. has a water supply well that is located 183 feet to the west. The locations of the water supply wells are depicted in Figure 2. According to the Geologic Map of North Carolina (Brown, et al, 1985), the site is located in the Charlotte Belt of the Piedmont Physiographic Region of North Carolina and is underlain by megacrystic to equigranular granitic rocks. The nearest surface water body is a pond located approximately 650 feet to the east. 9.0 CONCLUSIONS/RECOMENDATIONS Terraquest personnel supervised the excavation of contaminated soil beneath and surrounding the former heating oil UST located off the west side of the garage building. From assessment and remedial activities to date, the following conclusions/recommendations can be drawn. • The 280-gallon steel non-regulated, non-commercial heating oil UST was removed on July 31, 2023. • The analytical results of soil samples collected from native soils beneath the former heating oil UST location during a Phase II ESA confirms a release from the UST. Initial Abatement Action Report – Heating Oil UST Former BCA Property Mgmt., LLC Terraquest Environmental Consultants, P.C. 280 Ervin Woods Dr. Prepared on: September 14, 2023 7 Kannapolis, NC • 74.35 tons of heating oil-contaminated soil were excavated from beneath the 280-gallon heating oil UST and were hauled offsite for disposal at the Environmental Soils soil disposal facility in Lattimore, NC. • Groundwater was not encountered in the soil excavation. • Confirmation soil samples were collected from the sidewalls and base of the soil excavation. Analytical results of the collected soil samples revealed heating oil-type contaminant concentrations exceeding the NCDEQ DWM-UST Soil-to-Groundwater and Residential MSCCs in the base of the excavation (H.O. BE1 and H.O. BE2). • Additional soil excavation could not be completed at the base of the excavation since the maximum soil excavation was reached and the foundation of the garage was in close proximity to the limits of the excavation (sidewall H.O. SW3). • With the non-regulated, non-commercial nature of the former 280-gallon heating oil UST and the absence of water supply wells within a 150-ft. radius of the former UST basin, the release incident is eligible for a no further action with the completion of a Notice of Regulatory requirements for soil and groundwater and public notification. 10.0 LIMITATIONS This report is limited to the investigation of petroleum hydrocarbons in soil and does not imply that other unforeseen adverse impacts to the environment are not present at or around the Former BCA Property Mgmt., LLC property. In addition, subsurface heterogeneities not identified during the current 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 vary over time. The opinions and conclusions determined in this report are in accordance with industry-accepted geologic and hydrogeologic practices at this time and location. No warranty is implied or intended.

TPH Total Petroleum Hydrocarbon UST Underground Storage Tank VOA Volatile Organic Analysis VOC Volatile Organic Compound VPH Volatile Petroleum Hydrocarbons MNA Monitored Natural Attenuation 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 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 8260 method, a TerraCore® sampler is used to collect three 5-gram allotments of soil. All three allotments are placed in methanol-preserved 40 mL vials. Also, two 5-gram allotments of soil are placed into sodium bisulfate-preserved 40 mL vials (5-gram each vial) 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 Methods 8270 and TPH 5030 and 3550 are placed in a 250-mL glass jar. TPH 5030 samples are preserved in methanol similar to the 8260 analysis. Field personnel wear new, disposable latex 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) meter, is inserted into the bag and the relative concentration of total VOCs is measured and permanently recorded in a field note book. VOC 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 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 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. Other Methods of Groundwater Sampling Geoprobe Screen Point 15/16 Groundwater Samplers The Screen Point 15/16 Groundwater Samplers are used to collect groundwater samples from unconsolidated materials at depths ranging from near ground surface to over 100 feet below grade. The depth that can be reached with the SP15/16 samplers is a function of the equipment and methods being used to advance the sampler (manual, static vehicle weight, or percussion probing), the formation being penetrated, and operator experience. These protected screen samplers have only five parts, including the grout plug, plus a few O-rings. Using either of these tools with O-rings on the rod fittings enables you to collect representative groundwater samples from a discrete interval using a bailer, bladder pump, or tubing and stainless steel check valve. The length of the stainless steel screen exposed to the formation can be set from just a few inches to as much as 41-inches to let you select the sampling zone. The stainless steel screen is a v-wire screen and has a 1.0 in. OD. The screen bore is 0.65 in. The stainless steel screen is wire-wound with a 0.004-in slot width. 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 added to samples directly after they are collected 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, sent 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. Non-Petroleum 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 added to samples directly after they are collected 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, sent 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 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, 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. 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 latex 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 added to samples directly after they are collected if 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, sent 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. Water Supply Well Sampling Groundwater samples from water supply wells are collected from sampling points, typically spigots, located in the closest proximity to the water supply 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 and the appropriate acid preservatives are 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, 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. 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, 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. 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 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.

SITELAB’s CAL-025 GRO Module is used to detect volatile petroleum hydrocarbons in the C6 to C10 range. This test matches well to EPA Methods for GRO, BTEX, BPH or VOC’s using GC/FID instrumentation. SITELAB’s CAL-042 EDRO Module is used to detect petroleum hydrocarbons in the C10 to C36 diesel and oil range. This test matches well to EPA methods for TPH, EPH, DRO, and others using GC-FID instrumentation. Prior to field usage, the UVF TRILOGY is calibrated with five calibration standard solutions per targeted analyte. Soil samples are weighed to the nearest gram (i.e. 5.0 g) and added to a 1-ounce HDPE Nalgene bottle with a measured amount of laboratory grade methanol to the nearest mL (i.e. 10 mL) to create a sample extract. After addition of both the soil and methanol, the bottle is agitated for several minutes. Next, the sample rests for several minutes allowing for the soil and methanol extract to separate. After ample resting time, the methanol extract is collected with a syringe. A filter is connected to the end of the syringe and dispensed into a clean sample test tube. The test tube is labeled with sample ID and extract dilution factor (i.e. 2X). Known amounts of extract are pipetted into a second test tube and diluted with methanol. The sample ID and dilution factor are labeled on the test tube (i.e. 100X). Samples are placed into a clean cuvette and carefully inserted into the selected UV Module. Prior to analyzing the sample, the stored calibration that matches the UV Module being used, is selected. The UVF TRILOGY produces a result that when multiplied to the dilution factor equals the true TPH value. Quenching occurs when the detector is swamped by too many or certain type of hydrocarbons, producing low or negative concentrations. The sample is tested at multiple dilutions to confirm the results are linear and accurate. Solvent blank samples are periodically analyzed to confirm the solvent is clean and the calibration of the machine is maintained.
