Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 3 SECTION B. EXECUTIVE SUMMARY 1. Source Information According to the LUST Action Plan prepared by the NCDENR, DWM‐UST Section, dated December 12, 2008, the Franklin County Health Department notified the UST Section of groundwater contamination in the on‐site water supply wells in February 1983. At the time, two water supply wells were present on the subject property, one active and one inactive/abandoned. The UST Section identified two former convenience stores/ petroleum stations located north (former Davis Store) and east (former Woods Store) of the subject site. The tanks at both petroleum stations were reportedly abandoned around 1977. At the UST Section’s request, the active on‐site water supply well was reconditioned in 1983. Subsequent testing indicated that petroleum contamination was present in both on‐site water supply wells. Groundwater contamination was subsequently identified through the installation of monitoring wells at the site and in locations to the north and east of the supply well on the subject property. No USTs are known to have existed on the Saint’s Delight Baptist Church property. Surrounding USTs have included those removed from offsite locations. Two USTs were reportedly removed from the northern adjacent property (former Davis store) in 1977. Four USTs were removed from the eastern adjacent property (Former Woods Grocery) prior to 1977. There is no information regarding non‐UST sources of petroleum storage such as aboveground storage tanks (ASTs) on the Saint’s Delight Baptist Church property. Historical reports indicate that a 100‐gal kerosene UST was formerly located along the southern side of the former Woods Store on the eastern adjacent property, however the method of closure for this tank is unknown. A 250‐gal AST that appears to have contained waste oil products was until recently located along the southern wall of the former Woods Store. Based on a conversation with Mr. Jeff Wood (grandson of the former Woods Grocery owner), several USTs were removed near the northern end wall of the existing structure on the Woods Grocery property, and a pump island was (reportedly) located in front of the former store. These are likely the USTs that were reportedly removed prior to 1977. 2. Initial Abatement Actions Abatement activities performed in association with the release at the site, to date, include the following:  Two USTs were reportedly removed from the northern adjacent property (former Davis store) in 1977.  Four USTs were removed from the eastern adjacent property (Former Woods Grocery) prior to 1977.  Additional abatement action activities were conducted relative to Incident # 3887 under the guidance of the NCDEQ, UST Section, Federal and State Lead Cleanup Program. Abatement activities were completed during June 2020 which included the excavation and off‐site disposal of 966.56 tons of petroleum contaminated soils from two areas on the former Woods Grocery property. Excavation of soils focused on areas previously identified as having petroleum‐related compounds present at levels in excess of Soil‐to‐Groundwater Maximum Soil Contaminant Concentrations (MSCCs). Excavation of soils was limited in the vertical WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 4 extent to approximately 14‐ft beneath surface grade at their deepest, where weathered rock impeded additional deeper excavation. Following collection of confirmatory soil samples and prior to backfilling of the excavated areas, materials were emplaced in contact with groundwater within each excavated area to facilitate oxidative degradation of petroleum contaminants in site groundwater. These materials included 1,708 pounds of potassium persulfate (PeroxyChem Klozur KP™), 1,432 pounds of fast sodium persulfate and 275 pounds of Iron EDTA activator. Persulfate materials were emplaced into each excavated area, while the ETDA was mixed with water and added to the excavated areas. Following the emplacement and mixing of these materials, the excavations were backfilled to match surface grade. 3. Results of Hydrogeological Investigation Shallow groundwater flow beneath the site is towards the west, with a southerly component, which is consistent with land surface topography in the area. Depths to groundwater measured on September 24, 2021, ranged from 6.40 feet (ft) below the well top of casing (TOC) in MW‐5 to 13.85‐ft below TOC in MW‐11. Based on groundwater elevations, the water table gradient trends toward the west. The depth to underlying bedrock is greater in the western portion of the site. Based on aquifer slug testing performed on three wells at the site during September 2021, the average groundwater hydraulic conductivity was calculated to be 4.7‐ft/day or 1.7 x 10‐3 cm/s (arithmetic mean) or 4.1‐ft/day or 1.4 x 10‐3 cm/s (geometric mean). The shallow monitoring wells at the site are screened within the residual soils and saprolite that were derived from the in‐place weathering of underlying granitic bedrock that underlies this portion of Franklin County. Deeper monitoring wells are screened within the underlying partially weathered rock (PWR) and competent bedrock. Below the water table, all the pore space within the residual soils, saprolite and PWR, and fractures within competent bedrock are saturated with groundwater. These continuous saturated materials form the unconfined aquifer that underlies the site. Therefore, petroleum contaminants introduced into the shallow portion of the aquifer by the UST systems can enter lower portions of the unconfined aquifer through the processes of diffusion, dispersion and natural groundwater flow conditions. 4. Results of Soil, Groundwater & Free Product Assessment Soil Assessment September 2015: One or more petroleum‐related compounds were identified at concentrations in excess of the established Soil‐to‐Groundwater MSCCs in eighteen of twenty‐five samples submitted for analysis by EPA Method 8260. EPA Method 8270 analysis results showed naphthalene present in four of the twenty‐five soil samples submitted for analysis at levels above the Soil‐to‐Groundwater MSCC for the compound. June 2020: Soil samples obtained at the conclusion of over‐excavation activities completed in June 2020 showed the following: WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 5 Excavation 1 ‐ One or more petroleum‐related compounds were reported in samples SW1‐1, SW1‐2, SW1‐3, SW1‐4, SW1‐6, SW1‐7 and SW1‐8. One or more compounds reported in samples SW1‐1, SW1‐2, SW1‐3, SW1‐4, SW1‐6 and SW1‐8 were identified at concentrations exceeding the established Soil‐to‐Groundwater MSCCs. No compounds were reported in any of the samples at levels above the established Residential or Industrial/Commercial MSCCs. Excavation 2 ‐ One or more petroleum‐related compounds were reported in each of the samples obtained from the periphery of Excavation 2 at concentrations exceeding the established Soil‐to‐Groundwater MSCCs. No compounds were reported in any of the samples at levels above the established Residential or Industrial/Commercial MSCCs. Results of soil sampling completed following over‐excavation of petroleum contaminated soils show that several compounds remain in un‐excavated areas at levels above their Soil‐to‐ Groundwater MSCCs. Affected soils appear to include soils between approximately 6‐ft in depth extending to the upper surface of the weathered rock interface, encompassing the areas located between the two excavations, along their western edges and extending to the west into the NCDOT right‐of‐way of Firetower Road (Figure 4). Groundwater Assessment Analytical results for groundwater samples obtained from site monitoring wells during March 2023 combined with those for samples collected from wells installed during October 2023 indicated the presence of one or more compounds in samples obtained from shallow wells MW‐2RR, MW‐4, MW‐6RR, MW‐8 and MW‐9 at concentrations exceeding their 2L Standards defined by North Carolina Administrative Code (NCAC) Title 15A, Subchapter 02L, Section .0202 (Water Quality Standards for Class GA Groundwater). Benzene (MW‐2RR) and 1,2‐dibromoethane or “EDB” (MW‐2RR and MW‐8) were reported at concentrations exceeding the Gross Contaminant Level (GCL) for the compounds. Shallow Groundwater Based on combined data from March and October 2023, the lateral extent of shallow groundwater contamination in the surficial aquifer has not been defined to levels equivalent to the 2L Standards in the following directions:  East and south of MW‐8; and  South and west of MW‐9 Benzene concentrations that exceed the GCL appear to be centered around MW‐2RR, located just west of the former pump island location on the Woods Grocery property. EDB concentrations that exceed the GCL also appear to be centered near MW‐2RR extending to the location of MW‐ 8 (south of MW‐2RR). Deep Groundwater Delineation of the vertical extent of contaminants within the deeper parts of the aquifer at the site has not been completed to date. Laboratory results for groundwater samples obtained from deep monitoring wells MW‐1S, MW‐2D, MW‐3D, MW‐4D, MW‐5D, MW‐6D and MW‐8D showed one or more petroleum‐related compounds at concentrations exceeding their respective WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 6 2L Standards. These compounds included benzene, 1,2‐dichloroethane, 1,2‐dichloropropane and naphthalene. Based on current data, the vertical extent of groundwater contamination by these compounds has not been determined in areas to the south of MW‐2D. Historical laboratory results for several water supply wells located in proximity to the site have shown impact by petroleum compounds, including benzene, EDB, MTBE and naphthalene at concentrations exceeding 2L Standards on one or more occasions. Because the shallow portion of the unconfined aquifer is hydraulically connected to the deeper portion of the aquifer, groundwater produced by the nearby water supply wells apparently contains some of the same petroleum‐related compounds as those present in shallow and deep groundwater at the site. NCDEQ maintains a point‐of‐entry (POE) system on the church parsonage well (WSW‐5) and had maintained a POE system on supply well WSW‐4 prior to the sale of the property to the present owner in December 2015. Free Product Assessment No free product has been identified in any wells or borings associated with assessment activities conducted at the site. 5. Risk Classification and Criteria At present, the site has been ranked by NCDEQ as an “High” risk site with a ranking of H510D. Criteria for this risk assignment include the following:  The site and surrounding properties located within 1,500‐ft of the release area are provided potable water exclusively through private water supply wells.  No alternative water supply system (e.g., municipal water system) approaches to within 1‐mile of the site, nor are there near‐future plans to incorporate the area into the Franklin County water supply system.  Several petroleum‐related compounds in the surficial aquifer have been documented at concentrations in excess of their 2L Standards.  Benzene and EDB have been documented in one or more groundwater samples at levels in excess of their GCLs.  Petroleum contaminants have been identified at concentrations exceeding the 2L Standards and/or the US EPA Region IV Maximum Contaminant Level(s) MCL(s) in water produced by several water supply wells located in proximity to the site, including the Saint’s Delight Baptist Church parsonage well (WSW‐5). 6. Target Levels for Soil & Groundwater Cleanup The “High” risk classification infers that the cleanup levels for the site will be the lowest of the soil‐ to‐groundwater/residential MSCCs for constituents in soil and the NCAC 2L Standards for any constituents in groundwater. As impacts to one or more supply wells have been documented in proximity to the release, the lower of either the 2L Standards or the US EPA Region IV Maximum Contaminant Levels (MCLs) would be appropriate cleanup levels for groundwater. Soils WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 7 The MSCCs for soil contaminants identify individual compounds and the established screening levels. As a criterion for screening contaminated soils, the Soil‐to‐Groundwater MSCCs are designed to identify the maximum contaminant levels available to leach to and impact groundwater adversely, based on groundwater use and availability of alternate water supplies. These screening levels are considered to be the most stringent in terms of “allowable” contaminant concentrations and are used in the case of the Saint’s Delight Baptist Church site as there are no alternate water supplies available to the site and surrounding area, and all properties within 1,500‐ ft of the source area rely on private supply wells for potable water. Groundwater As all properties located within 1,500‐ft of the site rely on private water supply wells, and in the absence of an alternative water supply for the site and surrounding properties, the target cleanup levels for groundwater contamination at the site should be the 2L Standards. These standards are applied to the site as the groundwater of the area is classified as Class GA Groundwater [NCAC Title 15A, Subchapter 02L, Section .0201 (Groundwater Classifications)]. Class GA Groundwater is listed as an “Existing or potential source of drinking water supply for humans.” “This class is intended for those groundwaters in which chloride concentrations are equal to or less than 250 mg/l, and which are considered suitable for drinking in their natural state, but which may require treatment to improve quality related to natural conditions.” The 2L Standards as they apply to individual contaminants identified in groundwater are listed under NCAC Title 15A, Subchapter 02L, Section .0202 (Groundwater Quality Standards). These standards exist for the protection of Class GA Groundwater as potential sources for drinking water. Drinking Water In the case of a supply well showing impacts by the release, the lower of the NC 2L Standards or the US EPA Region IV MCL would serve as the appropriate screening level for contaminants. Where no MCL is listed, the 2L Standard for the compound, or the laboratory detection limit if no 2L Standard exists would be appropriate. Petroleum Vapor Intrusion While not evaluated specifically for petroleum vapor intrusion (PVI) impact at the facility, the lack of free product and vertical separation between the structure(s) on the site and groundwater would likely result in the site being deemed not at risk for PVI based on vertical screening distance alone. 7. Actions for Reduction of Risk Actions for reduction of risk at the facility should include lowering the concentrations of groundwater contaminants to levels equivalent to or near the established 2L Standards. However, risk will still be associated with the release at the facility as several potable supply wells are situated in proximity to the source area, and no alternative water supply is available or planned for the site or surrounding properties.

SITE HISTORY AND CHARACTERIZATION The following information summarizes the site history and characterization. 1 UST Information No USTs are known to have existed on the Saint’s Delight Baptist Church property. Surrounding USTs have included those removed from offsite locations. Two USTs were reportedly removed from the northern adjacent property (former Davis store) in 1977. Four USTs were removed from the eastern adjacent property (Former Woods Grocery) prior to 1977. Historical reports indicate that a 100‐gal kerosene UST was formerly located along the southern side of the former Woods Store on the eastern adjacent property, however the method of closure for this tank is unknown. A 250‐gal AST that appears to have contained waste oil products from farming operations was until recently located along the southern wall of the former Woods Store. Based on a conversation with Mr. Jeff Wood grandson of the former Woods Grocery owner, several USTs were removed near the northern end wall of the existing structure on the Woods Grocery property, and a pump island was reportedly located in front of the former store. Available information relating to the presence of USTs formerly located on properties near the site is included in Table B‐1. The location of the site imposed on the USGS Topographic Map for the vicinity is included as Figure 1. Site improvements, including current structures, overhead and buried utilities, former USTs and monitoring well locations are depicted on Figure 2. 2 AST, Petroleum Spills & Other Non‐UST Petroleum Releases No AST, petroleum spills or other non‐UST petroleum releases have been documented in the immediate vicinity of the Saint’s Delight Baptist Church property. 3 Description of Release/General Assessment History  January 1989: The NCDENR (now NCDEQ) & CD Memo states that a call was received from Rev. A.R. Hite regarding gasoline contamination in groundwater in the vicinity of Saint’s Delight Baptist Church near Louisburg. Bottled water service was initiated for the church property in 1989.  December 1990: State Laboratory of Public Health reported traces of 1,2‐Dichloroethane in the church well.  January 1991: The NC Department of Human Resources, Epidemiology Branch, based on analytical results, declared that the water should be considered safe for normal usage.  July 1991: A Request for Investigation showed that the water supply well at the Church and parsonage has shown gasoline contamination. Potential sources were inconclusive; no alternate water sources were available, and oral consumption of hazardous substances was reported.  August 1991: Leaking UST Trust Fund Site Recommendation. Intended to get water sample to determine pesticide or petroleum contamination. Reports indicated the ex‐preacher may have treated the Church & parsonage buildings with pesticides. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 9  September 1991: Phase I Subsurface Investigation performed. Four (4) WSWs (Arnold Up‐ gradient Well, Arnold Original Well, Parsonage Well & house on east side of SR1022) were sampled & 5 soil borings were sampled. The results indicated petroleum contamination at both former stores. The investigation confirmed the presence of petroleum soil contamination particularly present at the former Woods Store.  April 1992: Five WSWs reportedly sampled with results indicating petroleum contamination.  July 2003: WSW Sampling Event & SRS. Force Environmental Service Company, LLC (Force) sampled six WSWs within 1,500’ radius; five of the six WSWs had been impacted. All five indicated levels of benzene, the EPA MCL for benzene (5 ppb) had been exceeded in three of the five WSWs. The 2L Standard for benzene (1 ppb) had been exceeded in all five WSWs. WSW‐5, located at the parsonage, had the highest benzene level at 17 ppb. The 2L Standard for 1,2‐dichloroethane (0.38 ppb) was also exceeded in WSW‐5 at the parsonage.  April 2004: Monitoring well installation and WSW and groundwater sampling report completed by Force Environmental. Twelve soil borings were completed to depths ranging from 6 to 15‐ft beneath land surface (BLS). The borings with the highest photoionization detector (PID) reading were converted into monitoring wells (MW‐1 through MW‐7, respectively). Groundwater samples were collected from five of the monitoring wells (MW‐1 & 3 were dry). The 2L Standards and the EPA Standards for benzene, ethylbenzene, toluene, and total xylene were exceeded in MW‐1. The 2L Standard for EDB was also exceeded in MW‐1. The 2L Standards for benzene, ethylbenzene, total xylene, and naphthalene were exceeded in MW‐4. The only constituent detected in MW‐5 was total xylenes, and the detections were below the 2L and EPA Standards. Three of the six WSWs were sampled. WSW‐5 (parsonage) & WSW‐6 located at 517 Fire Tower Road had petroleum constituent levels that exceed both the 2L Standards and the EPA Standards. According to information provided by the UST Section, based on the constituent levels in WSW‐5 & 6, groundwater flow, and high constituent levels in MW‐2 and 4, it is possible that the pumping of WSW‐5 & WSW‐6 is causing the impacted groundwater to be pulled into the bedrock and towards the wells. It was recommended to excavate approximately 450 tons of impacted soil around the Wood building and MW‐1, 2 & 3 in an attempt to eliminate a residual source. Installation of a deep bedrock well between MW‐2 and Fire Tower Road was also recommended. The investigation around Davis Store indicated that there is soil and groundwater impact at that site. It is possible that a release occurred and could also be affecting the WSWs. It was recommended to sample the WSW located just southwest of the Davis Store site to determine if it has also been impacted. Monthly supply of bottled water was being provided to residences by NCDEQ.  September 2008 – December 2008: In September 2008, monitoring wells MW‐4, MW‐5, MW‐7 and water supply wells WSW‐2, WSW‐5, and WSW‐6 were sampled by SGS Environmental Services. Monitoring well MW‐4 and water supply wells WSW‐5 and WSW‐6 contained petroleum concentrations exceeding the 2L Standard. In November and December 2008, water supply wells WSW‐2, WSW‐4, and WSW‐Johnson were sampled. Water supply well WSW‐2 contained petroleum‐compound concentrations exceeding the 2L Standard. WSW‐4 contained a benzene concentration below its 2L standard.  According to the Monitoring Well and Water Supply Well Sampling Event Report by Force dated December 29, 2008; benzene has been historically detected at concentrations exceeding the 2L Standards in the groundwater samples collected from WSW‐2, WSW‐4, WSW‐6, and WSW‐Johnson. Benzene and methyl tert‐butyl ether (MTBE) had been detected in the WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 10 samples collected from WSW‐3 in 1991 at levels exceeding the established 2L Standards. Benzene, 1,2‐dichloroethane, and MTBE (once in 1991 for MTBE) have been historically detected exceeding the established 2L Standards in the groundwater samples collected from the active on‐site water supply well (WSW‐5). No petroleum‐related constituents were detected in the groundwater samples collected from WSW‐1.  August 2009: S&ME collected water samples from five nearby water supply wells (WSW‐2, WSW‐2A, WSW‐3, WSW‐5, and WSW‐6). S&ME attempted to collect water samples from two additional water supply wells, WSW‐4 and WSW‐Johnson, but the wells were inaccessible. In addition, historical reports were unclear about the location of WSW‐2 [548 Fire Tower Road (WSW‐2) vs. 562 Fire Tower Road (WSW‐2A)]; therefore, S&ME collected groundwater samples from both water supply wells. Concentrations of benzene were detected in the samples collected from WSW‐2A and WSW‐3 exceeding its 2L Standard. Concentrations of benzene (9.3 ppb) and 1,2‐dichloroethane (1.0 ppb) were detected in the groundwater sample collected from WSW‐6, exceeding the established 2L Standards. No petroleum‐related constituents were detected in the groundwater samples collected from WSW‐2 and WSW‐5.  November 2012: Three monitoring wells (MW‐2R, MW‐3R, and MW‐ 6R) were installed at the site by S&ME. Groundwater flow was established to the northwest after surveying was completed. Groundwater samples were collected from six monitoring wells (MW‐2R, MW‐3R, MW‐4, MW‐5, MW‐6R, and MW‐7). The laboratory analytical results of the groundwater samples indicated that several volatile organic compounds (VOCs) were reported at concentrations exceeding the established 2L Standards in monitoring wells MW‐2R, MW‐4, and MW‐6R. Monitoring wells MW‐2 and MW‐3 were also abandoned. Water samples were collected from four water supply wells, WSW‐2A, WSW‐3, WSW‐5, and WSW‐6. The laboratory analytical results for the water samples indicated that benzene and 1,2‐ dichloroethane were detected above the 2L Standard in WSW‐3. At the request of NCDENR, S&ME re‐sampled WSW‐3 on December 10, 2012. The sample collected from WSW‐3 was analyzed by two separate laboratories (Pace and ConTest). The laboratory analytical results of the re‐sampling of WSW‐3 indicated that benzene was detected in concentrations exceeding the 2L Standard in both laboratory analyses. In addition, 1,2‐dichloroethane was detected in a concentration exceeding the 2L Standard in the analysis for WSW‐3 performed by Pace.  December 2012‐January 2015: Periodic sampling of the POE systems have been conducted by water provision contractors.  April 2015: WR performed groundwater and supply well sampling activities at the site. Analytical results for groundwater samples analyzed by SM 6200B showed several petroleum‐ related compounds at levels exceeding the established 2L Standards in monitoring wells MW‐ 1, MW‐2R, MW‐4, and MW‐6R. Benzene and naphthalene were detected above their 2L Standards in monitoring wells MW‐1, MW‐2R, MW‐4, and MW‐6R. None of the compounds identified in the samples were reported at levels exceeding the established GCLs. No petroleum‐related compounds were reported in the samples retained from MW‐3R, MW‐5, or MW‐7. Analytical results for supply well samples obtained from the influent of the POE system attached to WSW‐5 indicated the presence of benzene and 1,2‐dichloroethane at concentrations that exceed the 2L Standards. No petroleum‐related compounds were reported in the samples retained from water supply WSW‐2A or the effluent of the POE system attached to WSW‐5. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 11  September 2015: WR performed soil sampling on the former Davis Store property and the former Woods Store property located to the north and east of the site, respectively, in an effort to define the extent of soil contamination at each location. One or more petroleum‐ related compounds were identified at concentrations in excess of the established Soil‐to‐ Groundwater MSCCs in eighteen of twenty‐five samples submitted for analysis by EPA Method 8260. EPA Method 8270 analysis showed naphthalene present in four of the twenty‐ five soil samples submitted for analysis at levels above the Soil‐to‐Groundwater MSCC for the compound. No compounds were reported at concentrations in excess of the established Residential or Industrial/Commercial MSCCs. Contaminants identified in the soil samples were restricted to samples obtained from borings installed on the Wood property. Those contaminants identified on the Wood property were found in and surrounding the areas of disturbed soils identified through GPR and assumed to be the former location(s) of USTs previously closed at the facility. No compounds were reported in any soil samples obtained from locations at the former Davis Store (Ted Gupton) property.  December 2015: Following the sale of the property on which supply well WSW‐4 is located, the POE system at the location was removed in accordance with NCDEQ policy.  February 2016: WR performed and sampling of monitoring wells MW‐1, MW‐2R, MW‐3R, MW‐4, MW‐5 and MW‐7, sampled supply wells WSW‐4, WSW‐5 (Pre‐and Post‐POE) and WSW‐7, and placed UNIREM® PRP™ Well Booms in monitoring wells MW‐2R and MW‐4. Analytical results for groundwater samples obtained in February 2016 indicated the presence of several compounds in samples from monitoring wells MW‐2R and MW‐4 at concentrations exceeding the established 2L Standards. No compounds were reported at concentrations exceeding the established GCLs. Analytical results for the pre‐POE sample obtained from WSW‐5 indicated the presence of benzene and 1,2 dichloroethane at concentrations exceeding the established 2L Standards. The concentration of benzene detected in the sample also exceeded the US EPA MCL. Analytical results for the post‐POE sample obtained from WSW‐5 did not show any petroleum‐related contaminants at levels exceeding the laboratory method detection limit for SM6200B, indicating that the POE system was, at the time, effectively removing/sequestering contaminants associated with the supply well. Analytical results for supply well samples obtained from WSW‐4 and WSW‐7 did not show petroleum‐ related compounds at levels above the MDL for SM6200B.  April 2017: WR performed a sampling event at the facility on April 17 and 20, 2017, which included the sampling of monitoring wells MW‐2R, MW‐3R, MW‐4, MW‐5 and MW‐7, and the sampling of supply wells WSW‐4 and WSW‐6. Following groundwater sampling, Universal Remediation, Inc. (UNIREM) PRP® Well Booms were placed in wells MW‐2R and MW‐4. WR was tasked with the collection of groundwater samples from wells MW‐1 and MW‐6R; however, MW‐1 was found to be dry upon gauging, and MW‐6R could not be found and was assumed to be located beneath a large pile of wood debris. Analytical results for groundwater samples obtained from site monitoring wells in April 2017, and analyzed by SM6200B, indicated the presence of one or more petroleum compounds in samples obtained from MW‐ 2R and MW‐4. One or more compounds detected in samples from these wells were reported at concentrations in excess of the established 2L Standards. Analytical results for samples obtained from WSW‐4 showed the presence of benzene at a concentration of 0.755 ppb, a level beneath the 2L Standard (1.0 ppb) and the US‐EPA MCL of 5.0 ppb. Results for the sample from WSW‐6 did not show the presence of VOCs at concentrations exceeding the laboratory MDL. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 12  June 2018: WR completed a groundwater and supply well sampling event at the facility. Analytical results for groundwater samples obtained in June 2018 indicated the presence of one or more petroleum‐related compounds in samples from monitoring wells MW‐2R and MW‐4 at concentrations exceeding the established 2L Standards. No compounds were reported at concentrations exceeding the established GCLs. No petroleum‐related compounds were reported in samples from wells MW‐3R, MW‐5 or MW‐7 at concentrations above the laboratory MDL for SM6200B.  October 2018: WR completed a receptor survey update relating to the release at the location. WR noted that a change to the ownership of the Wood parcel (WSW‐2 and WSW‐2A) had occurred since the passing of Mr. Harold Wood in October 2017. The parcel is now owned/managed by the HR Wood Estate, in care of Ms. Emily Angel of Madison, NC. Several surface water bodies (un‐named ponds or impoundments) were found to lie within 1,500‐ft of the site. Two of these features (noted in Table B‐5B) approach to within 1,000‐ft of the site – one approximately 730‐ft northwest and the other approximately 630‐ft west. WR contacted Mr. Alex Fuller, Assistant Director of the Franklin County Public Utilities Department, to inquire about the potential for a water line installation at the location of the site in the future. Mr. Fuller did not issue a response; however, WR spoke with a customer service representative who indicated to WR that at present there are no plans to install a water line in the vicinity of the site. The site is located along a topographic ridge with an approximate elevation of 870‐ft above mean sea level (MSL). Overland flow generally trends to the west from the site towards an un‐named surface water body situated approximately 1,200‐ft west of the location. This un‐named surface water drains as a tributary of Back Creek, which discharges to Cypress Creek and ultimately the Tar River, within the Tar River Basin. The site is not located within the Coastal Plain Physiographic Region of North Carolina. The NC Source Water Assessment Program (SWAP) administered by the NCDEQ‐Public Water Supply Section does not identify any well head protection of community supply wells within ½ mile of the source area at the site. As properties within 1,000‐ft of the source area rely on potable supply wells as their sole means of water supply, the site risk remains high. Based on findings associated with the performance of the receptor survey update, no substantive changes were noted relating to the status of surrounding supply wells.  January 2020: WR performed a sampling event at the site on January 29, 2020, which included the sampling of monitoring wells MW‐1, MW‐2R, MW‐3R, MW‐4, MW‐5 and MW‐7, and the sampling of supply wells WSW‐4, WSW‐5 (pre and post‐POE), WSW‐6 and WSW‐7. Following groundwater sampling, Provectus® ORS™ Well Booms were placed in wells MW‐ 2R and MW‐4. Analytical results for groundwater samples obtained from site monitoring wells in January 2020 indicated the presence of one or more petroleum‐related compounds in samples obtained from MW‐2R and MW‐4 at concentrations in excess of the established 2L Standards. No compounds detected in these samples were reported at levels exceeding the established GCLs. Analytical results for the sample obtained from WSW‐4 showed the presence of benzene and 1,2‐dichloroethane at concentrations above the established 2L Standards but beneath the US‐EPA MCLs for each compound. Analytical results for the samples obtained from WSW‐5A (influent) showed benzene and 1,2‐dichloroethane at concentrations above the established 2L Standards. Benzene was reported in the sample at a level above the US EPA MCL. Results for the samples from WSW‐5A (effluent) showed benzene and 1,2‐dichloroethane at concentrations above the established 2L Standards. Benzene was reported in the sample at a level above the US EPA MCL. Results for WSW‐5 WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 13 (Influent and Effluent) indicate that these (and several other compounds) have broken through the point‐of‐entry system in place at the site. Laboratory results for WSW‐2, WSW‐6 and WSW‐7A did not show the presence of compounds petroleum‐related by SM6200B at concentrations exceeding the laboratory MDL.  June 2020 – WR oversaw the performance of initial abatement activities at the site in an effort to remove as much grossly impacted soil (relating to the known release on the former Woods Grocery property) as feasible. The excavation of contaminated soils was to be performed focusing on the removal of soils identified as having compounds present at levels in excess of the Soil‐to‐Groundwater MSCCs, extending to depths which intersected and underlie the surficial aquifer beneath the location. As a part of the remedial action, chemical amendments were to emplaced in contact with and into the surficial aquifer. To these ends, WR oversaw the excavation of a total of 966.56 tons of impacted material to remove petroleum contaminated soils in the vicinity of the former pump island location (west of the structure on the property) – identified as “Excavation 1”, and to the south and west of the former location of the 100‐gal kerosene UST – identified as “Excavation 2”. Ultimately, soils were excavated from both area to depths of approximately 10 to 14‐ft beneath surface grade. In the course of the excavation of impacted soils, weathered rock was encountered at depths ranging from 8 to 13‐ft. Final excavations measured approximately 31 x 34‐ft x 12‐ft deep (Excavation 1) and 28‐ft by 18‐ft x 12‐ft deep (Excavation 2). The actual base of the excavations graded along the weathered rock interface from approximately 11‐ft beneath ground surface to the west, where the interface lied approximately 14‐ft beneath grade. Groundwater entered the excavations at depths of approximately 11‐ft beneath surface grade. Following excavation of contaminated soils and prior to backfilling the excavated areas, chemical amendments (fast‐ release and controlled‐release persulfates) were introduced into both areas in contact with surficial groundwater. One or more petroleum‐related compounds were reported in samples SW1‐1, SW1‐2, SW1‐3, SW1‐4, SW1‐6, SW1‐7 and SW1‐8. One or more compounds reported in samples SW1‐1, SW1‐2, SW1‐3, SW1‐4, SW1‐6 and SW1‐8 were identified at concentrations exceeding the established Soil‐to‐Groundwater MSCCs. No compounds were reported in any of the samples at levels above the established Residential or Industrial/Commercial MSCCs. One or more petroleum‐related compounds were reported in each of the samples obtained from the periphery of Excavation 2 at concentrations exceeding the established Soil‐to‐Groundwater MSCCs. No compounds were reported in any of the samples at levels above the established Residential or Industrial/Commercial MSCCs.  September 2021 – WR Completed an evaluation of the supply well (WSW‐5) servicing the church parsonage. Evaluation of the well was initiated following complaints by the well user that the point‐of‐entry (POE) system filters were clogging at a increased rates. Inspection of the well was performed by N.W. Poole Well & Pump Co. (Poole) on September 24, 2021. Results of the evaluation showed the following: o The pressure tank within the wellhead was found to be defective (waterlogged and holding 0‐psi). This condition was forcing all pressure within the system to originate from the well pump alone, likely adding to levels of sediment/solids being pumped from the well. o The total well depth was found to be approximately 115‐ft. o The static water level within the well was found to lie approximately 30‐ft beneath the well’s top of casing. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 14 o The well pump was found to be set at an approximate depth between 90‐ and 100‐ft. o Interference within the well thought to be the casing interface or a protective basket was encountered at a depth between 50‐ and 60‐ft. Following Poole’s evaluation of WSW‐5, Poole personnel replaced several fittings which had to be cut to gain access to the well. The well was then shock‐chlorinated to disinfect the well and re‐ energized after re‐sealing.  December 2021 – WR completed a Comprehensive Site Assessment in association with the site. Results of the CSA are incorporated into this CSA Addendum in following sections.  September 2022 – WR completed a groundwater and supply well sampling event at the location. Analytical results for groundwater samples obtained from site monitoring wells during September 2022 indicated the presence of one or more compounds in samples obtained from Type II wells MW‐2RR, MW‐4, MW‐6RR, MW‐8, MW‐9 and MW‐11 at concentrations exceeding their 2L Standards. Benzene and 1,2‐dibromoethane or “EDB” were reported at concentrations exceeding the GCL for the compounds in samples from wells MW‐ 2RR and MW‐8. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 15 SECTION D. RECEPTOR INFORMATION 1 Water Supply Wells WR did not perform a receptor update in association with the current task authorization for the site; however, WR personnel completed a receptor update during October 2018. The following receptors are present in the vicinity of the subject facility:  Two active private water supply wells are located within a 500‐ft radius of the release area on the site, each utilized as potable supplies. These wells include WSW‐5 (the church parsonage well) and WSW‐2 (located on the Woods property to the southeast of the source area). WSW‐ 5 is currently utilizing a POE system funded by NCDEQ.  Two supply wells (WSW‐4 and WSW‐6) are located between 500 and 1,000‐ft of the source location. These wells are situated to the south of the source area. WSW‐4 had been serviced by a POE system funded by NCDEQ up until December 2015. Per Department policy, the system was removed following the sale of the property to the present owner.  WSW‐7A is located approximately 1,150‐ft south‐southwest of the source location.  Municipal water service was (and is) not available to the site and surrounding properties, nor does the County have current plans for the installation of water services to the area.  No surface water bodies were identified within 500‐ft of the release area on the site.  The NC Source Water Assessment Program (SWAP) does not identify any community supply wells or designated wellhead protection areas within a ½‐mile radius of the site.  The site is located within the Tar‐Pamlico River Basin of North Carolina. The site is located near a topographic ridge with an approximate elevation of 380‐ft above mean sea level (AMSL). Overland flow generally trends to the west from the former Woods Grocery property towards the Saint’s Delight Baptist Church property. Locally this overland flow trends slightly south. The site is not located within the Coastal Plain Physiographic Region of North Carolina. As properties within 1,000‐ft of the source area rely on potable supply wells as their sole means of water supply, the site risk remains high. Private water supply well information is summarized in Table B‐5A, while additional receptor information is included in Table B‐5B. Supply well and additional receptor locations are shown on Figure 10. 2 Public Water Supplies In association with the receptor survey previously completed, WR contacted the Franklin County Public Utilities Departments to determine the status of any municipally owned water services in the vicinity of the site. Franklin County indicated that they did not maintain water services in the vicinity of the site location, nor were there any near‐future plans for the extension of County water lines to include the area of the site. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 16 3 Surface Waters No surface water features (e.g., lakes, ponds or streams) were identified within 500‐ft of the site. Two un‐named ponds approach to within 630‐ft west and 730‐ft northwest of the site. The water feature located to the west of the site is classified by the US Fish and Wildlife Service (US FWS), National Wetland Inventory (NWI) as a PUBHh Freshwater Pond Habitat described as "Palustrine, Unconsolidated Bottom, Permanently Flooded, Diked/Impounded". The remaining pond is not presently classified by the NWI and is utilized as a farm pond. 4 Wellhead Protection Areas The NC Source Water Assessment Program maintained by the NCDEQ‐Public Water Supply (PWS) Section does not identify any community supply wells or wellhead protection areas with a ½‐mile radius of the site. 5 Deep Aquifers in the Coastal Plain Physiographic Region The site is not located within the Coastal Plain Physiographic Province of the State, therefore deep aquifers in the Coastal Plain are not discussed herein. 6 Subsurface Structures Shallow subsurface structures including buried phone and cable television lines are present within the area of investigation. These lines cross the area of soil contamination from north to south within the NCDOT R/W, and according to a representative of Grid One (utility location services) are buried approximately 2 to 3‐ft beneath surface grade at the location. While crossing areas of soil contamination, it is not believed that these utilities are physically situated within contaminated soils. The approximate locations of these structures are included on Figure 2. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 17 SECTION E. LAND USE 1 Property Owners & Occupants The property is located at 565 Firetower Road in an unincorporated area of mixed‐use residential and agricultural properties within the corporate limits Louisburg, Franklin County, NC (Figure 1). The site and surrounding properties are zoned for residential, commercial, and agricultural land uses. The site includes a single‐story brick ranch‐style house with wood‐framed roof situated in the central portion of the subject property. The structure is currently used as a parsonage by the Saint’s Delight Baptist Church, located on the southern adjacent property. The remainder of the site consists of a gravel driveway and maintained grassy areas. Site features, including monitoring wells, water supply wells and offsite UST systems, are depicted on Figure 2. The Franklin County, NC Tax Department identifies the property comprising the site as parcel # 2845‐49‐9754, including 5.30 acres of land. The site is currently owned by Saint’s Delight Baptist Church, which obtained the property from Walter C. Collins in 1981. Properties abutting and surrounding the site are all rural residential properties. 2 Sensitive Land Use Features While only intermittently utilized for formal church functions, the Saint’s Delight Baptist Church can be classified as a sensitive receptor. No other potential sensitive receptors (e.g., churches, daycares or locations of public assembly) were identified within 1,500‐ft of the site. 3 Zoning The site and all surrounding properties are currently zoned “Agricultural‐Residential” (AR), described by the Franklin County Planning Department: “This district is established to promote a compatible mixture of agricultural, forestry, conservation, and very low‐density residential uses where few public services will be available. Protection of the environment, preservation of prime farmland, and the continuation of rural lifestyles are goals this district seeks to attain.” WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 18 SECTION F. REGIONAL AND SITE GEOLOGY 1 Regional Geology According to the 1985 Geologic Map of North Carolina, the site is located within the Raleigh Belt of the Piedmont Physiographic Province, within an area of intrusive rock. The formation underlying the location is described as “Granitic Rock”. This material is further described as “Megacrystic to equiangular, Castalia and Wilton Intrusives.” The Bedrock Geologic Map of Franklin County North Carolina identifies the underlying rock at the location as “granitoid facies” described as “Fine to medium‐grained, equigranular, unfoliated white to buff biotite granite.” Additional description of the bedrock of the area includes “Outliers of Coastal Plain and/or other unconsolidated sediments are present, though their extent is not well documented in most of the county. Quaternary alluvium is present in most major drainages.” Based on mapped contours provided by the Franklin County GIS department, the elevation of the site lies at approximately 380‐ft AMSL. Elevation drops slightly to the south. 2 Site Geology Soils identified at the location during investigative activities associated with this CSA included sand and silt materials, underlain by clayey silt, clay and partially weathered rock overlying bedrock. In general, the water table was found to occur near the interface of partially weathered rock and the overlying materials. Partially weathered rock was encountered at depths varying between 4‐ft beneath grade (MW‐3D), in close proximity to the church supply well (WSW‐5) and 17‐ft (MW‐ 12), located to the south‐southeast of the source location. The top of competent rock as encountered during the installation of the deep monitoring wells was shown at depths varying between 13‐ft (MW‐3D, MW‐4D and MW‐5D) and 35‐ft (MW‐2D). PWR was not noted to occur within the boring associated with MW‐2D. Boring logs associated with monitoring wells installed at the site in March and October 2023 are included in Appendix C, and the locations of those wells are shown on Figure 2.

SOIL SAMPLING RESULTS Soil Sampling Information Investigation of soils affected by the release at the facility was performed through:  Collection and analysis of soil samples associated with assessment (2015), and  Collection of confirmatory samples at the conclusion of over‐excavation in June 2020. Locations and analytical results for the soil sampling work completed at the site are included in WR’s CSA report prepared in December 2021. 1.1 Boring Installations and Soil Sampling – September 2015 WR performed soil sampling on the former Davis Store property and the former Woods Store property located to the north and east of the site, respectively, in an effort to define the extents of soil contamination at each location. One or more petroleum‐related compounds were identified at concentrations in excess of the established Soil‐to‐Groundwater MSCCs in eighteen of twenty‐ five samples submitted for analysis by EPA Method 8260. EPA Method 8270 analysis showed naphthalene present in four of the twenty‐five soil samples submitted for analysis at levels above the Soil‐to‐Groundwater MSCC for the compound. No compounds were reported at concentrations in excess of the established Residential or Industrial/Commercial MSCCs. Contaminants identified in the soil samples were restricted to samples obtained from borings installed on the Wood property. Those contaminants identified on the Wood property were found in and surrounding the areas of disturbed soils identified through GPR and assumed to be the former locations of USTs previously closed at the facility. No petroleum‐related compounds were reported in the soil samples obtained from locations at the former Davis Store (Ted Gupton) property. 1.2 Over‐Excavation Soil Samples – June 2020 Following excavation of impacted soils from the location during June 2020, confirmatory samples were obtained for submittal to a fixed based lab for analysis of VOCs by EPA Method 8260B. These included 8 soil samples from Excavation 1 (SW1‐1 through SW1‐8). Seven samples were from Excavation 2, identified as SW2‐1, SW2‐2 through SW2‐7. Analytical results for samples obtained from excavation sidewalls of the excavated areas analyzed by EPA Method 8260B showed the following: Excavation 1 One or more targeted VOCs were reported in samples SW1‐1, SW1‐2, SW1‐3, SW1‐4, SW1‐ 6, SW1‐7 and SW1‐8. One or more VOCs were reported in samples SW1‐1, SW1‐2, SW1‐3, SW1‐4, SW1‐6 and SW1‐8 at concentrations exceeding the established Soil‐to‐Groundwater MSCCs. No VOCs were reported at concentrations that were above the established Residential or Industrial/Commercial MSCCs. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 20 Excavation 2 One or more targeted VOCs were reported in each of the samples obtained from the periphery of Excavation 2 at concentrations exceeding the established Soil‐to‐Groundwater MSCCs. No VOCs were reported at concentrations above the established Residential or Industrial/Commercial MSCCs. 1.3 Investigative Results ‐ Soils Analytical results for soil samples obtained from locations across the site are indicative of a release of petroleum product from the product delivery line(s) or pump island formerly located on the Woods Grocery property. While targeted over‐excavation of contaminated soils reduced the mass of contaminants present in unsaturated soils in those areas excavated, additional contaminated soils remain in un‐excavated areas at levels above their Soil‐to‐Groundwater MSCCs. Affected soils appear to include soils occurring between approximately 6‐ft in depth extending to the upper surface of the weathered rock interface, encompassing the areas located between the two excavations, along their western edges and extending to the west into the NCDOT right‐of‐way (R/W) of Firetower Road. Based on available data, WR estimates the approximate lateral extent of soil that exhibits VOC concentrations above Soil‐to‐Groundwater MSCCs to encompass 2,250 square feet (ft2), including areas into which data gaps exist (west of the excavated areas extending into the NCDOT R/W of Firetower Road). Contaminants appear to extend from approximately 6‐ft beneath surface grade to at least approximately 11‐ft beneath grade, at which depth saturated soils are found. WithersRavenel Our People.

SITE HYDROGEOLOGY Investigation of site hydrogeology involved the installation/sampling/monitoring of shallow (Type II) monitoring wells including MW‐1 (abandoned), MW‐2 (destroyed), MW‐2R (abandoned), MW‐ 3 (destroyed), MW‐3R, MW‐4, MW‐5, MW‐6 (destroyed), MW‐6R (destroyed), MW‐6RR, MW‐7, MW‐8, MW‐9 MW‐10, MW‐11, MW‐12, MW‐13, MW‐14 and MW‐15 and deeper double ‐cased (Type III) wells MW‐1D, MW‐2D, MW‐3D, MW‐4D, MW‐5D, MW‐6D, MW‐7D and MW‐8D. Additional Type II Wells MW‐12, MW‐13, MW‐14 and MW‐15 and Type III wells MW‐1D, MW‐ 2D, MW‐3D, MW‐4D, MW‐5D, MW‐6D, MW‐7D and MW‐8D were installed between March and October 2023 at the site. 1.1 Monitoring Well Installations, Development and Survey Existing monitoring wells are situated at the locations depicted on Figure 2 and well construction details are shown in Table B‐7. Each of the existing monitoring wells were installed using auger drilling methods, utilizing 6.25‐inch diameter hollow‐stem augers, driven by a GeoProbe® track mounted DPT rig or through rotary air drilling methods. Drilling methods used in the installation of previously installed wells were not provided in well construction records. Type II monitoring wells MW‐12, MW‐13, MW‐14 and MW‐15 and Type III monitoring wells MW‐ 1D, MW‐2D, MW‐3D, MW‐4D, MW‐5D, MW‐6D, MW‐7D and MW‐8D were installed in association with this CSA addendum between March and October 2023 by Environmental Drilling & Probing Services, LLC (EDPS), an NC Certified Well Contractor located in Charlotte, NC. Wells completed by EDPS were installed utilizing a GeoProbe® track mounted 7822 DT rig employing augers or air rotary methods or a Canterra CT‐450 air rig. Existing Type II monitoring wells were constructed using sections of 2‐inch inner diameter (ID) Schedule (SCH) 40 PVC slotted well screen set at the base of each boring. The remainder of each well consists of 2‐inch ID SCH40 PVC riser pipe which extends to near surface grade. The annular space between the exterior of well screens and borehole was filled with clean‐washed #2 filter sand extending from the base of each boring to a minimum of one‐foot above the top of the screened sections. This sand pack was overlain by a minimum 1‐ft thickness of bentonite clay, which was hydrated after emplacement. The remaining annular space above the bentonite clay seal was backfilled with neat cement grout to surface grade. An 8‐rinch diameter steel flush‐ mounted protective cover was set over each wellhead in a concrete pad, and a locking well cap was placed on each well for security. Type III wells were constructed with six‐inch diameter ID outer casings set a minimum of 1‐ft into the uppermost rock surface when encountered. Each outer casing was grouted into place and the grout was allowed to cure before advancing the boring to greater depth and installing the well screen and inner casing riser pipe. These wells were finished using 5‐ft sections of 2‐inch ID SCH 40 PVC slotted well screen set at the base of each boring. The remainder of each well consists of 2‐inch ID SCH40 PVC riser pipe which extends to near surface grade. The annular space between the exterior of well screens and borehole walls was filled with clean‐washed #2 filter sand extending from the base of each boring to a minimum of one‐foot above the top of the screened WithersRavenel Our People.

This sand pack was overlain by a minimum 1‐ft thickness of bentonite clay. The remaining annular space above the bentonite seal was backfilled with neat cement grout to surface grade. An 8‐inch diameter steel flush‐mounted protective cover was set over each wellhead in a concrete pad, and a locking well cap was placed on each well for security. Construction records for monitoring wells installed as a part of this CSA Addendum are included in Appendix D, while construction details are included in Table B‐7. Historical groundwater elevation measurements are provided in Table B‐9. Following installation, each well was developed with an electric submersible pump to remove suspended sediment or trapped solids within the well sand pack, allowing for infiltration of representative groundwater at each location. Each well was developed until such a time as no appreciable suspended solids were discernable in water removed from the wells. TOC elevations for each well were determined through the surveying of each well TOC using an automatic laser level. The TOC for monitoring well MW‐1 (abandoned) was designated at the site benchmark, and assigned a relative elevation of 276.00‐ft. TOC elevations for the remaining wells were surveyed relative to the TOC elevation of MW‐1. 1.2 Well Gauging, Determination of Groundwater Flow and Hydraulic Gradient Groundwater levels within each of the wells on the site were measured on March 22, 2023 (MW‐ 3R, MW‐4, MW‐5, MW‐6RR, MW‐7, MW‐8, MW‐9 MW‐10, MW‐11, MW‐12, MW‐13, MW‐1D, MW‐2D, MW‐3D, MW‐4D, MW‐5D) and October 26, 2023 (MW‐14, MW‐15, MW‐6D, MW‐7D and MW‐8D) with an electronic water level indicator. These measurements were tabulated and the water levels within each well subtracted from the well TOC elevation to determine the relative groundwater elevation at each location. Shallow groundwater flow beneath the site is towards the west, with a southerly component, consistent with land surface topography in the area (Figure 3A). Depths to groundwater measured between March and October 2023, ranged from 5.20‐ft BTOC in MW‐14 and 12.36‐ft BTOC in MW11. Deeper groundwater flow within the fractured bedrock beneath the site is towards the west with northwestern and southwestern components which is consistent with land surface topography in the area (Figure 3B). Depths to groundwater within the deep monitoring wells measured between March and October 2023, ranged from 4.97‐ft BTOC in MW‐7D and 37.50‐ft BTOC in MW‐2D Groundwater measurements obtained in association with this CSA addendum are included in Table B‐7, while historical measurements are included in Table B‐9. 1.3 Aquifer Slug Testing and Determination of Hydraulic Conductivity WR completed rising head water‐level recovery tests (slug tests) on monitoring wells MW‐6RR, MW‐8 and MW‐9 in September 2021 to determine estimates of aquifer hydraulic conductivity. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 23 An In‐Situ LevelTROLL® 700 pressure transducer and data logger operating with WinSitu 5 software were employed to record water‐level recovery data during the tests. Slug tests were conducted through the introduction and withdrawal of a dedicated disposable bailer into each of the wells on which the testing was completed. The subsequent water level recovery or rising head results were recorded and later reduced for use in determination of hydraulic conductivity. Water‐level recovery data obtained during each test were used to calculate a hydraulic conductivity or “K” value based on the method of Bouwer, 1989. These values are summarized in the table below: Results of Aquifer Slug Testing Well ID Test Type K (ft/day) K (cm/sec) MW‐6RR Slug Out 7.3 2.6 x 10‐3 MW‐8 Slug Out 4.8 1.7 x 10‐3 MW‐9 Slug Out 2.0 6.9 x 10‐4 Arithmetic Mean 4.7 1.7 x 10‐3 Geometric Mean 4.1 1.4 x 10‐3 Based on aquifer slug testing performed on three wells at the site during September 2021, the average groundwater hydraulic conductivity was calculated to be 4.7‐ft/day or 1.7 x 10‐3 cm/s (arithmetic mean) or 4.1‐ft/day or 1.4 x 10‐3 cm/s (geometric mean). Parts of screened sections for each well on the site are situated in partially weathered rock and intercept the transition zone above competent rock. The calculated hydraulic conductivity values are considered to be representative of Piedmont saprolite and PWR that occurs within Franklin County. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 24 SECTION I. GROUNDWATER/SUPPLY WELL SAMPLING RESULTS Groundwater sampling as described herein includes samples collected from monitoring wells during March 2023 and October 2023; however, historical sampling of select wells has occurred since well installations dating back as early as December 2010. Analytical results for all groundwater and water‐supply well samples are summarized in Table B‐4A. 1.1 Groundwater Sampling: March – October 2023 Groundwater samples were obtained from monitoring wells MW‐3R, MW‐4, MW‐5, MW‐6RR, MW‐7, MW‐8, MW‐9 MW‐10, MW‐11, MW‐12, MW‐13, MW‐1D, MW‐2D, MW‐3D, MW‐4D, MW‐5D in March 2023 and MW‐14, MW‐15, MW‐6D, MW‐7D and MW‐8D in October 2023. Prior to the collection of samples, water levels within the wells were gauged with an electronic water level indicator and the wells were purged a minimum of three well volumes of water using separate, disposable polyethylene (PE) bailers. Representative groundwater collected from the wells following purging were decanted into laboratory prepared sample containers provided by Waypoint Analytical, LLC (Waypoint). Samples obtained from the wells were submitted to Waypoint for analysis of VOCs by Standard Method (SM) 6200B. Analytical results for these samples are discussed below. 1.2 Investigative Results ‐ Groundwater Analytical results for groundwater samples obtained from site monitoring wells during March and October 2023 indicated the presence of one or more VOCs in samples obtained from Type II wells MW‐2RR, MW‐4, MW‐6RR, MW‐8, MW‐9 and MW‐12 and Type III wells MW‐1D, MW‐2D, MW‐3D, MW‐4D, MW‐5D, MW‐6D and MW‐8D at concentrations exceeding the established 2L Standards. Benzene, EDB and 1,2‐DCE were reported at concentrations exceeding the established GCLs for those VOCs in the sample from MW‐8. Shallow Groundwater Based on current data, the lateral extent of groundwater contamination in the shallow portion of the unconfined aquifer has not been defined to levels equivalent to the 2L Standards to the east of MW‐8. WR estimates the approximate lateral extent of shallow groundwater impact to encompass approximately 54,000‐ft2 or just over one‐acre in size. Groundwater contamination appears to extend from the source area on the former Woods Grocery property to the west and south, which is consistent with the directions of shallow groundwater flow. Benzene at concentrations exceeding the GCL appear centered around the location of MW‐8, located just south of the former pump island location on the Woods Grocery property. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 25 Deeper Groundwater Assessment of groundwater within deeper portions of the unconfined aquifer has identified te presence of VOCs in samples from wells MW‐1D, MW‐2D, MW‐3D, MW‐4D, MW‐5D, MW‐6D and MW‐8D at concentrations exceeding established 2L Standards. Based on current data, the lateral extent of VOCs within deeper groundwater has not been completed to the south of MW‐ 2D. Historical laboratory results for several water supply wells located in proximity to the site have shown impact by petroleum compounds, including benzene, EDB, MTBE and naphthalene at concentrations exceeding 2L Standards on one or more occasions. Each of these supply wells is likely completed within the fractured rock portion of the unconfined aquifer in the area. Pumping of the wells may have caused contaminated groundwater from the shallow portion of the aquifer to move downward into deeper portions of the aquifer. Laboratory results for groundwater samples collected from site monitoring wells are included in Table B‐4A. Results for the most recent groundwater sampling completed at the location are shown on Figure 4 and included in Table B‐4B. Isoconcentration maps depicting the estimated lateral extents of benzene, naphthalene and total xylenes in surficial groundwater are included as Figures 5, 6 and 7, respectively. Isoconcentration maps depicting the estimated lateral extents of benzene and naphthalene in samples obtained from Type III wells are included as Figures 8 and 9, respectively. The laboratory analytical reports associated with groundwater samples obtained in March and October 2023 are included in Appendix B. Cross‐sections that show the estimated extent of benzene inn shallow groundwater based on March – October 2023 data are shown on Figures 10 and 11, while cross‐sections that show the estimated lateral and vertical extents of benzene in deeper groundwater based on March – October 2023 data are shown on Figures 12 and 13.

FREE PRODUCT INVESTIGATION AND RECOVERY No free product has been identified in any monitoring wells installed as a part of assessment at the facility to date. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 27 SECTION K. DISCUSSION OF FINDINGS This report documents activities associated with assessment of a release from a UST system or systems formerly located at the former Woods Grocery property in Louisburg, NC which has contributed to groundwater contamination at the Saint’s Delight Baptist Church parsonage located to the west of the source location. Nature and Extent of Contamination/Maximum Contaminant Concentrations The soil and groundwater contamination at the facility are the result of a release of an unknown volume of gasoline from one or more of the UST systems formerly located on the Woods Grocery property. No information is available to aid in determining the volume or exact source of the release from the UST systems; however, based on levels of soil contamination identified near and to the west of the former pump island, it is believed that the release is the result of compromised structural integrity of one or more fittings associated with the product dispenser(s). Strong petroleum odors and staining were noted in soils removed during excavation activities completed on the property during June 2020. Collectively, results for soil samples obtained from locations across the site are indicative of a release of petroleum product from the product delivery line(s) or pump island formerly located on the Woods Grocery property. While targeted over‐excavation of contaminated soils reduced the mass of contaminants present in unsaturated soils in those areas excavated, additional contaminated soils remain in un‐excavated areas at levels above their Soil‐to‐Groundwater MSCCs. Affected soils appear to include soils occurring between approximately 6‐ft in depth extending to the upper surface of the weathered rock interface, encompassing the areas located between the two excavations, along their western edges and extending to the west into the NCDOT R/W of Firetower Road (See Figure 4, Comprehensive Site Assessment, December 2021). Soils Based on available data, WR estimates the approximate lateral extent of soil impact remaining at concentrations above Soil‐to‐Groundwater MSCCs to encompass approximately 2,250‐ft2, including areas into which data gaps exist. Contaminants appear to extend from approximately 6‐ ft beneath surface grade to at least approximately 11‐ft beneath grade, at which depth saturated soils are found. Soil contaminants at levels exceeding the established Soil‐to‐Groundwater MSCCs were reported in eighteen of twenty‐five samples collected in association with assessment at the location, and in thirteen of fifteen samples obtained following the completion of over‐excavation during June 2020. Note that the locations of samples collected during assessment (SB‐1 through SB‐25) obtained during September 2015 were undercut during the excavation of soils in June 2021. Contaminants remaining at levels exceeding the Soil‐to‐Groundwater MSCCs appear as common components of petroleum fuels and appear to relate directly to the release on the Woods Grocery property. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 28 Groundwater Based on current data, the lateral extent of shallow groundwater contamination has not been defined to levels equivalent to the 2L Standards to the east of MW‐8. WR estimates the approximate lateral extent of shallow groundwater contamination to encompasses approximately 54,000‐ft2. This estimate includes unassessed areas of groundwater impact to the east of MW‐8. Groundwater contamination appears to extend from the source area on the former Woods Grocery property to the west and south. Benzene at concentrations exceeding the GCL appear centered around MW‐8, located just south of the former pump island location on the Woods Grocery property. Assessment of deeper groundwater has identified petroleum‐related contaminants in wells MW‐ 1D, MW‐2D, MW‐3D, MW‐4D, MW‐5D, MW‐6D and MW‐8D at concentrations exceeding the established 2L Standards. Based on current data, the extents of deeper groundwater contamination at concentrations exceeding 2L Standards has not been completed to the south of MW‐2D. The extents of impact in remaining directions has or has nearly been defined to levels approximating 2L Standards. The greatest concentrations of contaminants are centered near monitoring well MW‐8, just south of the pump island formerly located on the property. As yet, it is unclear whether the contaminant plume is showing reductions based on depletion through natural means or in association with the chemical amendments emplaced in the excavated areas during June 2021. Future monitoring of groundwater conditions at the location will be a means to determine contaminant concentration trends at the site. No free product has been identified in any of the monitoring wells installed in association with assessment activities at the site. Contaminant Migration and Potentially Affected Receptors Soils Vertical migration of contaminants through the soil column in the area of petroleum release is evident by the current soil analytical data. Additionally, the data indicate that contaminated soils are interfacing with groundwater in the area of release. Shallow Groundwater The distribution of petroleum‐related VOCs within shallow groundwater I the vicinity of the site is consistent with the direction of groundwater flow determined from site measurements. The leading edge of the groundwater contaminant plume is migrating to the west, crossing beneath Firetower Road and extending into the Saint’s Delight Baptist Church property. WR estimates the approximate lateral extent of shallow groundwater impact to encompasses approximately 54,000‐ ft2, just over one‐acre in size. This estimate includes unassessed areas of groundwater impact to the east of MW‐8. WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 29 Deeper Groundwater The distribution of petroleum‐related VOCs within deeper groundwater in the vicinity of the site is consistent with the directions of deeper groundwater flow to the west, with northwest and southwest trends. The presence of petroleum‐related VOCs in samples of water from nearby water supply wells indicates that contaminants have migrated to deeper portions of the unconfined aquifer in the vicinity of the site. Site Specific Conditions or Actions that would result in lowering the risk classification or site priority ranking As no alternate water supply exists or is planned for the site or surrounding properties, the use of private supply wells will continue to serve as the sole means for obtaining potable water in the area. Six active supply wells are located within 1,500‐ft of the source area on the site, the nearest of which (WSW‐5) is located approximately 180‐ft down‐gradient of the source area. In the absence of an alternative water supply or remediation of affected groundwater to levels equivalent to or beneath the 2L Standard(s), the site risk and priority will remain high. Applicable Cleanup Levels The “High” risk classification infers that the cleanup levels for the site will be the lowest of the soil‐ to‐groundwater/residential MSCCs for constituents in soil and the NCAC 2L Standards for any constituents in groundwater. In the event of impact to a supply well located in proximity to the release, the lower of either the 2L Standards or the US EPA Region IV MCLs is an appropriate cleanup level. Soils The MSCCs for soil contaminants identify individual compounds and the established screening levels. As a criterion for screening contaminated soils, the Soil‐to‐Groundwater MSCCs are designed to identify the maximum contaminant levels available to leach to and impact groundwater adversely, based on groundwater use and availability of alternate water supplies. These screening levels are considered to be the most stringent in terms of “allowable” contaminant concentrations and are used in the case of the Saint’s Delight Baptist Church site as there are no alternate water supplies available to the location and surrounding area, and all properties within 1,500‐ft of the source area rely on private supply wells for potable water. Groundwater As all properties located within 1,500‐ft of the site rely on private water supply wells, and in the absence of an alternative water supply for the site and surrounding properties, the target cleanup levels for groundwater contamination at the site should be the 2L Standards. These standards are applied to the site as the groundwater of the area is classified as Class GA Groundwater [NCAC Title 15A, Subchapter 02L, Section .0201 (Groundwater Classifications)]. Class GA Groundwater is listed as an “Existing or potential source of drinking water supply for humans.” “This class is intended for those groundwaters in which chloride concentrations are equal to or less than 250 mg/l, and which are considered suitable for drinking in their natural state, but which may require treatment to improve quality related to natural conditions.” The 2L Standards (as they apply to WithersRavenel Our People. Your Success. Saint’s Delight Baptist Church WR Project # 23‐0307‐EM Comprehensive Site Assessment Addendum December 2023 30 individual contaminants identified in groundwater) are listed under NCAC Title 15A, Subchapter 02L, Section .0202 (Groundwater Quality Standards). These standards exist for the protection of Class GA Groundwater as potential sources for drinking water. Drinking Water In the case of a supply well or wells showing impact by the release, the lower of the 2L Standards or the US EPA Region IV MCL serves as the appropriate screening level for contaminants. Where no MCL is listed, the 2L Standard for the compound (if listed) should apply. Petroleum Vapor Intrusion While not evaluated specifically for petroleum vapor intrusion (PVI) impact at the facility, the lack of free product and vertical separation between the structures on the affected properties and groundwater would likely result in the site being considered not at risk for PVI based on vertical screening distance alone.

CONCLUSIONS AND RECOMMENDATIONS The release at the subject site has contaminated both soil and groundwater to levels exceeding their applicable regulatory limits. Soils exhibiting contamination at concentrations exceeding the Soil‐to‐Groundwater MSCCs have been identified at the site. Groundwater contaminants are present in numerous well locations at concentrations exceeding the established 2L Standards, and benzene, EDB and 1,2‐DCE have been reported at concentrations in excess of their GCLs in monitoring wells MW‐2RR and MW‐8 through past sampling. Based on site conditions and results acquired through the completion of the December 2021 CSA and this CSA Addendum, WR recommends the preparation of a Corrective Action Plan (CAP) for the release at the site. The goal of the CAP will be to identify potential remedies that can be used to reduce contaminant concentrations in soil and groundwater to acceptable levels. WR also recommends relocation and replacement of WSW‐5 at the discretion of NCDEQ. WR appreciates the opportunity to be of service in the completion of these assessment activities.

Your Success. Soil Sampling, Soil Boring and Monitor Well Installation, Well Development Soil borings are installed utilizing a stainless-steel hand auger, direct-push hydraulic drill or auger rotary drill using either a macro core™ sampler, hollow stem augers, or air rotary roller cone bit. Soil borings are typically sampled at discrete intervals from the bucket of a clean stainless steel hand auger, direct push stainless steel sampler with acetate sleeve, or a split barrel sampler. When appropriate, soil samples may be collected from drill cuttings associated with the boring or well installation. Monitor wells are constructed within select soil borings of one, two, or four-inch inside diameter PVC casing and machine slotted screen in accordance with NCAC Title 15A, Subchapter 02C (Well Construction Standards, Criteria and Standards Applicable to Water Supply and Certain Other Wells). Clean-washed “#2 Torpedo Sand” is typically utilized to fill the boring annulus surrounding the well screen, extending to a minimum of 1-foot above the well screen. A minimum 1-foot thick bentonite clay seal is emplaced above the sand pack and hydrated. Neat cement grout is placed in the remaining annulus space from the upper portion of the bentonite seal to within 1-foot of surface grade. In coastal plain areas where shallow groundwater is encountered, a variance to construction standards may be employed to ensure the upper portion of the well screen intersects the upper aquifer surface. Wellheads may be completed with either concrete-set flush mounted traffic-bearing steel skirted manholes with bolt down covers or steel above-ground “stick-up” well protectors set in a concrete pad. The monitoring wells are secured with locking caps. Temporary wells or piezometers may be completed with the PVC riser cut at or above grade, and are abandoned within 24-hours of their installation. Wells may be developed using a bailer, electric submersible pump, pneumatic pump, or peristaltic pump, dependent upon site conditions. When wells are developed by the driller, they may be developed with any of the methods outlined above, in addition to air or water injection. Soil boring logs and well construction details are typically prepared for presentation in a report appendix. Borings completed in bedrock may be drilled using air rotary, coring, or sonic drilling methods. Groundwater Depth to Water Measurements Groundwater level measurements are typically obtained using an electronic water level indicator which registers a tone and/or illuminated light when the probe contacts groundwater. Depth to groundwater measurements are obtained by lowering the probe attached to a cable usually marked in 0.01 foot intervals into the well until the probe of the meter intersects the water surface. The measurement from the top of the riser pipe or top of casing (TOC) to the water level is recorded to the nearest 0.01 foot. The electronic water level indicator probe and exposed probe cable is decontaminated between measurement locations.

Free Product Level Measurements Light Non-Aqueous Phase Liquid (LNAPL) or “free product” present on the water table is measured using an electronic oil/water interface probe. The interface probe has both an audible and illuminating light that indicate when a liquid level is encountered. The oil/water interface probe registers a solid tone and solidly lit light when LNAPL petroleum product is encountered and a beeping tone flashing light when groundwater is encountered. Depth to LNAPL measurements are obtained by lowering the probe attached to a cable marked in 0.01 foot intervals into the well until the probe of the meter intersects the product or groundwater. The measurements from the top of the riser pipe or TOC to the liquid level are recorded to the nearest 0.01 foot. The thickness of LNAPL is calculated by subtracting the depth to LNAPL measurement from the depth to groundwater measurement. The electronic interface probe is decontaminated between measurement locations. Soil Sampling and Field Screening Soil sampling is performed in general accordance with ASTM: 1586-84 where applicable. Sampling procedures are followed to protect the chemical integrity of the soil samples and minimize the potential for cross contamination between sample locations, including discarding of the exterior of the sample which contacts the auger bucket, acetate sleeve, or split barrel sampler, the use of stainless steel sampling equipment, and the thorough decontamination of sampling apparatus prior to use and between sample locations. Soil samples retained as a part of excavation or other intrusive “digging” activities may be collected from the bucket of excavation equipment or using a hand shovel, if appropriate. Care to collect soil samples from excavation equipment includes retrieving native soil from material that has not made contact with the excavating equipment. Samples are collected in sealable bags or by directly filling sample containers as described above. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination or field personnel exposure to contaminants. Sampling equipment such as hand auger extensions and buckets, direct push samplers, split spoons or shovels, are decontaminated prior to their use in the collection of samples. Samples are placed within laboratory grade sample containers provided by the laboratory to which the samples are submitted, labeled, sealed, and placed in an ice filled cooler. An aliquot of the sample is typically placed in a clean sealable bag and allowed to reach ambient air temperature for future screening of volatile vapor content with a photoionization detector (PID), flame-ionization detector (FID) or other portable screening device. Screening of samples with a PID, FID or other field screening device is performed in accordance with device manufacturer specifications for screening, following calibration of the instrument based on manufacturer recommended procedures. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Groundwater Sampling Groundwater samples are generally collected using one of three standard methods – through the use of a dedicated, disposable bailer, a peristaltic pump or submersible electric pump. When sampling with a bailer, a minimum of three well volumes of groundwater are extracted from the well as a means of purging, unless the well is purged to a “dry” state prior to the removal of three volumes of water. Prior to collection of the groundwater sample with the bailer, the water level is allowed to recover to within 80% of the original level measured prior to purging. When sampling with a peristaltic or submersible electric pump, polyethylene (PE) tubing (or equivalent) is emplaced into the screened section of the monitoring well, and the pump is used to extract water through the tubing. When using the either of these methods, general water quality measurements including but not limited to pH, temperature, dissolved oxygen (DO), oxygen reductive potential (ORP), specific conductivity and turbidity may be used as methods for determining when an adequate purge of the well has been conducted. When water quality parameters are measured, the resulting data are included in well purge forms or field notes specific to each site and sampling point. Following the purging of three well volumes of groundwater (in the case of the bailed well) or stability of monitored measurements (in the case of the peristaltic or submersible electric pump), the groundwater sample(s) are introduced directly into sample containers provided by the laboratory to which samples are ultimately submitted for analysis. Any samples requiring chemical preservation are contained in pre- preserved container(s) provided by the laboratory. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination of samples or field personnel exposure to contaminants. Water Supply Well Sampling Sampling of water supply wells is accomplished through the collection of a representative sample from an in-line water tap or other point accessible for sampling. Where possible, the sample is collected from a point prior to any filtration or point of entry (POE) system which might be installed on a well. In some cases, samples will be collected from both pre and post-POE locations. Prior to the collection of samples through an in-place sampling point, the tap or sampling port is cleaned with an Alconox® and deionized water solution, rinsed with deionized water, and again with an isopropyl alcohol (IPA) rinse. In the case of active supply wells (e.g., a well with a useable well pump with an active power supply), the well pump is energized and allowed to run for a minimum of ten (10) minutes time, after which a sample is contained in laboratory grade sample containers as described in the previous section. Water quality parameters may be (but are not necessarily) measured in association with the well purging. Supply wells without active power supplies are not generally sampled, as the well seal cannot be compromised by individuals not certified as a well contractor. However, in the case of a well with no power supply or pump installed, samples could be obtained through the use of a bailer, peristaltic pump or electric submersible pump. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Decontamination Procedures Decontamination procedures employed in the performance of field activities will vary dependent upon the method(s) of sampling performed at any site, but will generally include the following: • Remove excess soil/sludge from any sampling equipment as needed, • Wash and scrub the equipment with a phosphate-free detergent such as Alconox® or Liquinox® in a contaminant-free tap water solution. Use a brush to remove particulate matter and surface films as necessary, • Rinse thoroughly with tap water, • Rinse thoroughly with analyte-free water (deionized water),  Rinse thoroughly with isopropyl alcohol, • Allow the equipment to air dry, • Prevent inadvertent contamination during storage and transport (accomplished through storage of equipment in foil or plastic bags/sheeting). In the case of disposable bailers and tubing utilized for the purging and sampling of wells, these items may be decontaminated prior to their disposal. In general, no decontamination of these items is necessary prior to their use in sampling.

The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method. The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance. The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as- received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report.
