A brief summary of the groundwater monitoring and public outreach mailing activities is provided below, and a comprehensive set of updated analytical data tables and associated attachments is enclosed. Groundwater Monitoring In January 2024, H&H completed a groundwater monitoring event which included gauging water levels in all accessible site monitoring wells and collecting samples from nine monitoring wells (MW-1, MW-4I, MW-8, MW-9I, MW-9S, MW-10S, MW-12I, MW-12S, and MW-15S) to evaluate current groundwater concentrations at the site. The groundwater samples were submitted to Pace Analytical Services, LLC (Pace) for laboratory analysis of volatile organic compounds (VOCs) by EPA Method 8260. Based on H&H’s review of the laboratory report, Pace did not identify any quality assurance/quality control (QA/QC) issues that impact the usability of the data Ms. Ariana Rivera #C-1269 - Engineering July 16, 2024 #C-245 - Geology Page 2 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/DSCA - DS0/DS0-69 Brocks Cleaners/Reports/2024- 01 GWMR/CoverLetter.docx for the purposes of the assessment activities and conclusions documented in this submittal. Note, some of the samples were diluted due to high constituent concentrations, which resulted in elevated reporting limits. The groundwater analytical results indicate tetrachloroethylene (PCE) was detected at concentrations above the North Carolina 2L Standard (2L Standard) in each of the sampled monitoring wells except MW-12S. A notable concentration change was observed in deep near- source monitoring well MW-4I, where PCE increased from 8.61 milligrams per liter (mg/L) in January 2021 to a concentration of 55.3 mg/L in January 2024. However, the January 2024 concentration was within the range of historical fluctuations for this well. Previous remedial injections were performed at the site in 2009, 2011, and 2013 to promote enhanced reductive dichlorination of PCE. For the wells sampled in January 2024, PCE concentrations in monitoring wells MW-1, MW-9S, MW-10S, and MW-12I are notably lower than pre-injection concentrations. The injection activities stimulated biodegradation with increases in PCE degradation products, including trichloroethylene (TCE), cis-1,2-dichloroethylene (cis-1,2- DCE), and/or vinyl chloride, observed post-injection. In January 2024, PCE degradation products were detected above 2L Standards in each of the sampled monitoring wells, except MW-12S. The continued presence of PCE degradation products in site wells indicates that some breakdown of PCE is occurring. Notable increases in PCE degradation products were observed in MW-9I during the January 2024 monitoring event. In addition to chlorinated solvents, the petroleum-related compound benzene was detected for the first time in monitoring well MW-9I, at a concentration of 0.0038 J mg/L which slightly exceeds the 2L Standard of 0.001 mg/L. Public Outreach Mailing In January 2024, public outreach letters and water supply well information request forms were mailed to property owners within a 500-ft radius of the outer extent of the inferred groundwater plume associated with the site. No water supply wells were identified from the responses to the public outreach mailing. Notification letters were also mailed to the Tryon Town Manager, Polk Ms. Ariana Rivera #C-1269 - Engineering July 16, 2024 #C-245 - Geology Page 3 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/DSCA - DS0/DS0-69 Brocks Cleaners/Reports/2024- 01 GWMR/CoverLetter.docx County Environmental Health Supervisor, and Polk County Public Health Director along with a figure depicting the estimated area of groundwater contamination.

Groundwater samples were analyzed for volatile organic compounds (VOCs) by EPA Method 8260D. The maximum holding time for VOC analysis is 14 days from the sample collection date (when the sample is reserved in HCL). The samples were preserved with HCL and were analyzed within 14 days of collection. GWMR Form 2 Describe the standard quality assurance/quality control (QA/QC) procedures which are practiced in order to ensure that the samples are representative of actual conditions and that analytical results are valid. Describe the EPA approved methods used to extract and analyze the samples submitted the laboratory. Reference the maximum holding time for each type of analysis performed. The water level meter was decontaminated using Alconox detergent and distilled water after each well was gauged and sampled to avoid cross-contamination. New nitrile gloves and purge/sample tubing were used at each well. Samples were collected directly into laboratory-prepared sample containers, labeled with the site and sample identifications, time, date, sampler's initials, and analysis method. Samples were secured in protective bags before being covered with ice and cooled in a laboratory-supplied sample cooler. A sample chain-of- custody was completed and placed in the sample cooler. The sample cooler was delivered and relinquished to Pace Analytical Services in Huntersville, North Carolina under chain-of-custody protocol. The laboratory ran standard Type II QC measures on each set of samples. Groundwater samples were collected utilizing standard USEPA-approved low-stress (low-flow) purge techniques. Polyethylene tubing was placed in the middle of the well screen, secured at the top of the well, and connected to a short piece of silicone tubing at the peristaltic pump rotor. A second piece of polyethylene tubing was connected to the outflow side of the silicone tubing. Depth-to-water was then measured with a decontaminated water level probe, and the probe was set at the top of the water column. Groundwater was drawn through the tubing by the peristaltic pump at a rate that prevented drawdown of the water column in the well (approximately 100-150 mL/min at this site). Field measurements of temperature, pH, conductivity, dissolved oxygen (DO), oxidation-reduction potential (ORP), and turbidity were collected during the low-flow purging. Readings of each parameter were collected at 5- to 10-minute intervals. After field readings stabilized, samples were collected using the EPA-approved "soda straw" method. Samples were collected directly into laboratory-supplied containers.

In general, the detected groundwater PCE concentrations in the sampled wells appear to be within range of historical fluctuations. The presence of degredation products in groundwater, including TCE, cis-1,2-DCE, and/or vinyl chloride, indicate that breakdown of PCE is occurring. H&H recommends continued periodic monitoring at the site to further evaluate groundwater concentrations and plume stability at the site. Instructions: Discuss any trends or changes noted in analytical results. Conclusions Recommendations H&H conducted a limited groundwater monitoring event in January 2024 for select monitoring wells to evalaute current concentrations at the site. The primary constituents of concern (COCs) at the site are tetrachloroethylene (PCE) and its degradation products trichloroethylene (TCE), cis-1,2-dichloroethylene (cis-1,2-DCE), trans-1,2-dichloroethylene (trans- 1,2-DCE), and vinyl chloride which have been detected in groundwater at concentrations above NC 2L Standards. With the exception of MW-12S, PCE was detected at concentrations above the NC 2L Standard in each of the groundwater samples collected during the January 2024 monitoring event. Graphs of concentration vs time for select wells are provided in Attachment 8. As shown in the graphs, shallow wells located near and downgradient of the source area (MW-1 and MW-10S) have exhibited overall reductions as a result of previous injections. A notable concentration change was observed in deep near-source monitoring well MW-4I, where PCE increased from 8.61 mg/L in January 2021 to a concentration of 55.3 mg/L in January 2024; however, the January 2024 concentrations is within the range of historical fluctuations. Downgradient well MW-8 previously exhibited an increasing trend in PCE concentrations over time, however, the 2024 PCE concentration in this well was lower than the previous two events indicating that concentrations may potentially be stabilizing. The continued presence of PCE degradation products TCE, cis-1,2-DCE, and/or vinyl chloride in site wells indicates that some breakdown of PCE is occurring. cis-1,2-DCE Note: Other constituents have been detected at the site.

Table 1: Site Chronology DSCA ID No.: DC750001 Chronology of Events General Tryon, Polk County, North Carolina. Based on information provided to ENSR by the North Carolina Department of Environmental and Natural Resources (NCDENR), the facility was constructed and has operated since 1948. From approximately 1948 to 1984 petroleum based dry-cleaning solvents were used during cleaning operations. From approximately 1984 to present, Brock's Cleaners has utilized tetrachloroethylene (PCE) as the dry-cleaning solvent. Currently, a fourth generation cleaning machine is in operation at the facility. In addition, a 100-gallon aboveground storage tank (AST) located on the southwest outside wall of the cleaners was used to store PCE for less than one year in July 2001 Chlorinated solvent compounds were detected in soil and groundwater samples collected during a preliminary environmental assessment performed by Clark Environmental Services, P.C. (Clark) in July 2001 (Clark, 2001). August 2005 Clark completed a site Prioritization Assessment (PA). Results of the PA revealed the presence of dissolved chlorinated solvents in the subsurface. Due to shallow bedrock, soil impacts are limited to the vicinity of the former above ground storage tank. within 1,500 feet of the site. The area within 1,500 feet of the site is served by municipal water supplies provided by the town of Tryon. Subsurface utilities in the area are constructed to depths that intersect groundwater at regular intervals. October 2006 ENSR conducted a limited fracture-trace analysis in order to evaluate if fractured bedrock may be controlling groundwater flow direction. Results of the fracture-trace analysis suggest that fractures in the area trend northeast- southwest with a complementary subparallel set oriented northwest-southeast, which correlates to the expected regional structural trend. The findings indicate that the likely direction of groundwater flow at the site is toward the northeast. December 2006 the Tryon Public Works (TPW-MW-1, TPW-MW-2, TPW-MW-3, and TPW-MW-4). Wells at the Tryon Public Works (TPW) property were installed to monitor petroleum contaminants from an underground storage tank (UST) release at MW-2. Six surface water samples (SW-1 through SW-6) were collected at off-site locations along two unnamed tributaries of April 2007 ENSR conducted a Gore™ Module (GM) soil gas survey to evaluate the VOC plume distribution using qualitative soil gas sampling techniques. The results indicated the vapor-phase VOC plume extends northeast of the site beyond the northeast corner of the intersection of Maple Street and Palmer Street north of the site. February 2008 groundwater impacted with VOCs. The nine newly installed wells and seven existing wells were sampled to determine VOCs concentrations in groundwater. June 2008 ENSR installed and sampled three soil gas wells (SG-1, SG-2, and SG-3) on two residential properties located downgradient of Brocks Cleaners. ENSR conducted a well camera survey of monitoring wells MW-5i and MW-6i to determine the location and orientation of rock fractures in the well boring, if present. No major water bearing fractures were observed in the boring during the survey. As a result, wells MW-5i and MW-6i were completed with 5 feet of screen from 30-35 ft bls and 41-46 ft bls, respectively. Soil borings were advanced using hand auger equipment to bedrock refusal (1 to 4 feet below ground surface) at eight sampling locations (three interior and five exterior) to assess the vertical and horizontal extent of VOC impacted soil on (PID) and Color-Tec® kits equipped with PCE detector tubes. Soil analytical results revealed that PCE impacted soil is generally confined to the area directly under the concrete slab of Brock's Cleaners. suspected at the facility.Commence with the first date a problem was suspected and continueDate ADT 1 Page 1 of 4 Table 1: Site Chronology DSCA ID No.: DC750001 Chronology of Events Instructions:Brief description of all significant events that have occurred since a problem was suspected at the facility.Commence with the first date a problem was suspected and continueDate ADT 1 October 2008 ENSR sampled three soil gas wells (SG-1, SG-2, and SG-3) on residential properties of Jacot and Dalton located downgradient of Brocks Cleaners. ENSR also collected 1 air sample from the crawl space of the each of the Jacot and Dalton houses. In order to sample background air concentrations, ENSR collected 3 outdoor air samples from adjacent to the Jacot and Dalton houses and adjacent to the Brock's Cleaners facility. ENSR also collected soils from the source area and groundwater from MW-4i to conduct a bench scale sodium permanganate and sodium persulfate treatability study. December 2008 Groundwater samples were collected from all site monitoring wells and three monitoring wells at the Tryon Public Works (TPW-MW-1, TPW-MW-2, TPW-MW-3, and TPW-MW-4) facility in order to gauge baseline groundwater contaminant concentrations prior to upcoming pilot scale injections in 2009. Groundwater samples collected from all wells were analyzed for VOCs. Groundwater samples from MW-1, MW-3, MW-4s, MW-4i, MW-8, and TPW-MW-4 were analyzed for natural attenuation parmameters including nitrate, nitrite, nitrogen (TKN), sulfate, sulfide, alkalinity, chloride, carbon dioxide, methane, ethane, ethene, total iron, dissolved iron, total manganese, dissolved manganese, total organic carbon (TOC), biochemical oxygen demand ( BOD), and chemical oxygen demand (COD). May 2009 resolution and for monitoring the effectiveness of upcoming pilot scale injections. The newly installed wells were sampled to determine VOC concentrations in groundwater. July 7 - July 10, 2009 AECOM installed monitoring wells MW-9i, MW-13s, and MW-13i in the downgradient portion of the plume (in the right of way of Howard St.) in order to complete horizontal and vertical delineation. AECOM also installed 13 shallow injection wells and three (3) shallow piezometers inside Brock's cleaners and in its immediate vicinity. All of the monitoring wells and piezometers were sampled for baseline conditions. Injection wells IW-3, IW-8, and IW-13 were sampled for baseline conditions, and the remaining injection wells were developed by surging and pumping. July 13 - July 16, 2009 AECOM installed monitoring wells MW-11s, MW-11d, MW-12s, and MW-12i on White Oak Manor properties downgradient of Brock's Cleaners to complete horizontal and vertical delineation of the VOC plume. All of the monitoring wells were sampled for VOCs. July 22 - July 24, 2009 AECOM injected ~900 gallons of Anaerobic Biochem (ABC) in 13 injection wells beneath Brocks cleaners and immediately upgradient of the source area. September 2009 AECOM collected groundwater samples from 8 site wells for the 1-month post-injection monitoring. October 2009 AECOM collected groundwater samples from 9 site wells for the 2-month post-injection monitoring. November 2009 samples from seven locations. December 2009 AECOM collected groundwater samples from 9 site wells for the 4-month post-injection monitoring. January 2010 AECOM collected groundwater samples from 10 site wells for the 5-month post-injection monitoring. March 2010 AECOM collected groundwater samples from 11 site wells for the 7-month post-injection monitoring. June 2010 AECOM collected groundwater samples from 12 site wells and air samples from four locations near the Dalton residence. February 2011 AECOM collected air samples from four locations near the Dalton residence. April 2011 AECOM collected baseline groundwater samples and conducted a round of injections of ABC+ (ABC, plus zero valent iron). As part of the site activities, seven injection wells (IW-14 to IW-20) and four monitoring wells (PZ-4 to PZ-7) were installed. In addition, 25 temporary injection points (IP-1 to IP-25) were installed.

On August 23, 2011, monitoring well MW-14S was installed on the off-site adjacent property to the northewst of the site. On January 25, 2012, H&H submitted a Groundwater Monitoring Report to the DSCA Program documenting the groundwater sampling activities. April 2012 H&H conducts a site-wide groundwater monitoring event including the sampling of 23 site monitoring wells and the collection of 4 surface water samples. October 2012 H&H conducts a groundwater monitoring event including the sampling of 18 site monitoring wells and the collection of 1 surface water sample. February 2013 H&H submits a Groundwater Monitoring Report documenting the April 2012 and October 2012 sampling events. June - July 2013 and BR-IW-3). BR-IW-1, BR-IW-2, and BR-IW-3 were installed as bedrock injection wells upgradient of MW-4I, which currently has the highest VOC concentrations at the site. MW-15s and MW-15i were installed downgradient of the injection wells to monitor injection performance. In July 2013, H&H conducts a baseline groundwater monitoring event including the sampling of 7 site monitoring wells, including the newly installed wells and existing wells MW-4i August - September 2013 H&H attempts to inject 1,100 gallons of SRS®-FR Emulsified Vegetable Oil (EVO) solution into bedrock wells BR-IW- 1, BR-IW-2, and BR-IW-3. The bedrock injection wells were first purged of static water. Then, a concentration of 10:1 water to EVO solution was mixed and injected with pressure into the bedrock wells via a transfer pump and manifold system. After the EVO solution filled the bedrock well screen, riser, and sand pack, additional EVO could not be BR-IW-3. On September 3, 2013, H&H purged the 10:1 EVO solution from bedrock wells BR-IW-2 and BR-IW-3 and poured a more concentrated EVO solution (10:2) into the wells until injectant reached the top of casing. On September 13, 2013, H&H submitted an Injection Event Record to the UIC Program documenting the injection activities. October 2013 H&H submitted a Well Installation and Bedrock Injection Report to the DSCA Program documenting the installation of monitoring wells MW-15s and MW-15i and injection wells BR-IW-1, BR-IW-2, and BR-IW-2 and the injection activities completed in August and September 2013.

December 2018 In December 2018, H&H conducted soil gas sampling at three properties located downgradient of Brock's Cleaners: the Windstream building (SG-6 and SG-7; 215 Palmer Street), Vacant Residence (SG-1; 62 Maple Street), and the Dalton Residence (SG-3; 74 Maple Street). On February 14, 2019, H&H submitted a letter report to the DSCA Program documenting the soil gas sampling activities and results. January 2021 H&H conducted a limited groundwater monitoring event, including sitewide gauging and the sampling of five site monitoring wells (MW-1, MW-4I, MW-8, MW-10S, and MW-15S) for VOCs. In addition, three surface water samples (SWS-1, SWS-2 and SWS-3) were collected from the unnamed tributary to Vaughn Creek located in the downgradient portion of the site for analysis of VOCs. On April 16, 2021, H&H submitted a Groundwater Monitoring Report documenting sampling activities and results to the DSCA Program. January 2024 In January 2024, H&H completed a limited groundwater monitoring event at the site to evaluate current groundwater conditions. The monitoring event included site-wide gauging of monitoring wells and collection of groundwater samples from nine monitoring wells (MW-1, MW-4I, MW-8, MW-9I, MW-9S, MW-10S, MW-12I, MW-12S, and MW-15S). In addition, a public outreach mailing was sent out in early January 2024 to property owners within 500 ft of the inferred plume and to City/County officials. In Julye 2024, H&H submitted a Groundwater Monitoring Report to the DSCA Program documenting the groundwater monitoring and public outreach activities.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.

You are receiving this letter because the Division is performing site-related work in the area. We want to make you aware of the activities being conducted and provide you with someone to contact if you have questions. The Division has a program that addresses releases of dry-cleaning solvent, called the Dry- Cleaning Solvent Cleanup Act (DSCA) Program. The Brocks Cleaners site was certified into the DSCA Program in August 2005 after information became available that a release of dry-cleaning solvent had resulted in contamination, and we are continuing to investigate the extent of that contamination in the area. Some activities that may be conducted are the following: searching for water supply wells, collecting soil samples, installing and sampling groundwater monitoring wells, indoor air sampling, etc. Obtaining samples from private properties may be a part of this investigation. The DSCA Program’s contractors will be reaching out to the Polk County Health Department to request records regarding possible water supply wells in the area. If you have additional guidance on who the contractors should contact, please respond to this letter via the contact information indicated below. If you would like to view the location of the Brock’s Cleaners dry-cleaning facility site or review additional reports for the site, please go to deq.nc.gov/ncdsca and view the instructions for the use of the DWM Site Locator Tool and Online Documents.

You are receiving this letter because the Division is performing site-related work in the area. We want to make you aware of the activities being conducted and provide you with someone to contact if you have questions. The Division has a program that addresses releases of dry-cleaning solvent, called the Dry- Cleaning Solvent Cleanup Act (DSCA) Program. The Brocks Cleaners site was certified into the DSCA Program in August 2005 after information became available that a release of dry-cleaning solvent had resulted in contamination, and we are continuing to investigate the extent of that contamination in the area. Some activities that may be conducted are the following: searching for water supply wells, collecting soil samples, installing and sampling groundwater monitoring wells, indoor air sampling, etc. Obtaining samples from private properties may be a part of this investigation. The DSCA Program’s contractors will be reaching out to the Polk County Health Department to request records regarding possible water supply wells in the area. If you have additional guidance on who the contractors should contact, please respond to this letter via the contact information indicated below. If you would like to view the location of the Brock’s Cleaners dry-cleaning facility site or review additional reports for the site, please go to deq.nc.gov/ncdsca and view the instructions for the use of the DWM Site Locator Tool and Online Documents. If you have questions, please contact the DSCA Program’s independent contractor for this project, Mr. Kyle McDaniel with Hart & Hickman, PC, at kmcdaniel@harthickman.com or (704) 586- 0007. If you still have questions after contacting Mr. McDaniel, please contact the DSCA Program Project Manager, Ms. Ariana Rivera at ariana.rivera@deq.nc.gov or (919) 707-8352.
