Superfund Technical Assessment and Response Team (START) submits this letter report summarizing activities associated with the Blue Ridge Plating site (the site) in Arden, Buncombe County, North Carolina, conducted on February 28 through March 1, 2022. This report includes five enclosures and two attachments. Enclosure 1 contains figures illustrating the site location, site layout, and sampling locations. Enclosure 2 includes data summary tables. Enclosure 3 contains the photographic log. Enclosure 4 contains the monitoring well sampling forms. Enclosure 5 contains the Tetra Tech review of field quality control samples. Attachment 1 contains the laboratory data packages. Attachment 2 contains the EPA Regional Screening Levels (RSL) (target cancer risk TR=1E-06, target hazard quotient THQ=0.1) for residential soil to groundwater (May 2023). Background The Blue Ridge Plating (BRP) site is located at 171 Glenn Bridge Road, Arden, Buncombe County, North Carolina and occupies 3.06 acres. See Figure 1 in Enclosure 1. No structures remain on the property due to the EPA’s emergency response action (December 2014 through May 2015). The site is bounded to the north by Glenn Bridge Road; to the east by Business Park Circle and several commercial establishments; to the south and west by wooded areas and an auto repair business that is also along Business Park Circle; and to the west by Beale Road, including the intersection of Glenn Bridge Road and Beale Road and residential housing beyond. See Figure 2 in Enclosure 1. BRP was a metal plating company, which operated from 1974 to 2014. It used black oxide, cadmium, chromium, copper, cyanide, tin, and zinc in the electroplating processes. From 1974 to 1985, electroplating wastes were collected in drums located in the basement of a former structure where plating sludges were filtered out and the wastewater was directed to a 70,000-gallon in-ground concrete lagoon located behind the shop. Plating sludges were shipped off site for disposal and the wastewater was either sprayed on the ground or reused as process water. Between 1985 and 1990, the wastewater was discharged to the local municipal sewer system. In 1990, the municipality suspended access to the sewer system because BRP was not meeting pretreatment Mr. C. Zeller Page 2 August 22, 2023 requirements. After that suspension, BRP employed a closed loop reclamation system, which was in the basement of the former structure. Trip Description On January 24, 2023, EPA tasked START to locate and collect groundwater samples from ten previously installed off-site monitoring wells associated with the BRP site. The ten monitoring wells to be sampled are designated as follows, where “S” refers to shallow wells and “D” refers to deep wells: MW13S/13D, MW15S/15D, MW16S/16D, MW17S/17D, MW18D, and MW20D. Along with sampling, basic water data including depth to groundwater table, pH, DO, ORP, and water temperature were collected. These parameters and other information gathered during the sampling event were recorded on the monitoring well sampling forms included in Enclosure 4. Between February 28 and March 1, 2023, START David Reed and Julian Rizzi traveled to the site, located the ten monitoring wells, and collected groundwater samples from each well for analysis. See Figure 3 in Enclosure 1 and Enclosure 3. Prior to, and during well purging, a Herron dipper-T was used to monitor the depth to ground water, and a Horiba Water Quality Monitor was used to collect basic water data and ensure proper well stabilization prior to sampling. A Mega-Monsoon water sampling pump with an adjustable flow rate was used to purge all ten monitoring wells and collect samples. After sampling activities were concluded, Tetra Tech START processed, packaged, and shipped all samples to the EPA Region 4 Laboratory Services and Applied Science Division (LSASD) Laboratory Services Branch (LSB) in Athens, Georgia, for volatile and semivolatile organic compound, and metals analysis. The LSB analyzed all samples for volatile organic compounds by Method CLP SFAM01.1, semivolatile organic compounds by Method CLP SFAM01.1 B, total metals by Method CLP SFAM01.1 MS, and total mercury by Method CLP SFAM01.1 CV. Tables of the EPA-validated analytical results can be found in Enclosure 2. A summary of Tetra Tech’s review of field quality control samples is contained in Enclosure 5. The laboratory data packages can be found in Attachment 1. Analytical Results All analytical results were compared to the maximum contaminant level allowed in drinking water (MCL). MCLs were extracted from the EPA RSL tables contained in Attachment 2. Results for 1,1-dichloroethene exceeded the MCL two samples, MW13D and MW15S. Mr. C.

This review was performed on the following field quality control (QC) samples: field blanks, trip blanks, and field duplicate samples. The review of the field QC samples was performed in accordance with the Quality Assurance Project Plan, Superfund Technical Assessment and Response Team (START V), EPA Region 4, Revision 2 (February 2021), the EPA National Functional Guidelines (NFG) for Organic Superfund Methods Data Review (November 2020), and the EPA NFGs for Inorganic Superfund Methods Data Review (November 2020). This review was performed because the U.S. Environmental Protection Agency, Region 4, Laboratory Services and Applied Science Division, Office of Quality Assurance does not review these types of field QC samples as part of their validation effort. This policy was stated during a data validation webinar held on February 17, 2011. The webinar was attended by personnel from all 10 EPA Regions, as well as personnel from various agencies that utilize the EPA CLP and Regional Laboratories for analytical support. Field Blanks: Field blanks are generally aqueous samples that are exposed to the sampling environment or equipment at the time of sampling. Typically, one field blank is collected per field event of one week or less per lot of high-purity water used; for field events longer than one week, field blanks are collected at a frequency of one per week per lot of high-purity water used. One field blank was collected during the field sampling event. The field blank BRP-FL-01 had a detection of mercury. However, all associated samples were non-detect and no qualifications were applied. Trip Blanks: Trip blanks are used to assess the potential for sample contamination during handling, shipment, and storage. One trip blank was included within every shipping cooler of liquid or solid samples to be analyzed for VOCs. One trip blank, BRP-TW-01, was utilized for the sampling event for this project and no analytes were detected. Field Duplicate Samples: Field duplicate collection frequencies (one per twenty samples for each matrix) were met for this data set. A total of one groundwater field duplicate pair was collected for this sampling event. Analytical results for each analyte in field duplicate aqueous sample pairs must fall within less than or equal to 50 percent (%) relative percent difference (RPD). However, if at least one of the two results of the pair is below its minimum reporting limit (MRL) or one of the results is non-detect, then the absolute difference between the two results must be less than or equal to the MRL (using the MRL in the difference for the non-detect results). When results for a field duplicate sample pair fall outside the control limit for a particular analyte, the results for that analyte are qualified as estimated (flagged J or UJ) with an undetermined bias in both the parent sample and its field duplicate sample. For the field duplicate sample pair analyzed, all results met the acceptance criteria discussed above. ATTACHMENT 1 LABORATORY ANALYTICAL DATA PACKAGES (109 Pages) D.A.R.T.

The analytical results were reported in one sample delivery group (SDG) by the laboratory. In addition to the field samples, the laboratory analyzed two performance evaluation samples (PESs) for evaluating the laboratory’s performance with using the methods. A Stage 4 validation consisting of an electronic/manual review (S4VEM) was performed on the organic samples submitted for this case. The data package presents acceptable technical performance with qualifications. The laboratory satisfied all contractual and technical holding time limits. All results associated with erratic initial calibration (ICAL) and/or continuing calibration (CCAL) performance were flagged “J” with the appropriate Element® qualifiers (CLP16 and/or QC-1). The percent difference between an ICAL and a second source verification standard exceeded 20% for 3,3’-Dichlorobenzidine. The associated results were qualified “J” (QC-3). Deuterated Monitoring Compounds (DMCs) were used as surrogates in each sample for GC/MS analysis to monitor extraction efficiency. Pertinent data quality factors are discussed below. Trace Volatiles 1.The PES recoveries analyzed for Trace Volatiles were scored within limits by the web-based SPS Web software except for 1,2-Dichloropropane, which was scored Warning Low. Associated results were all non-detected and were qualified “UJ” (CLP-25). 5/24/23 11:31C231105 SVOA VOA FINAL 05 24 23 1131Page 2 of 80 D.A.R.T.

This package presents acceptable contractual and technical performance with qualifications. Additional details are provided below. Examination of laboratory blank samples revealed apparent low-level contamination for beryllium. Reported detection limits were adjusted as high as ten times the blank levels to discount possible false positives due to contamination in laboratory blanks. ICP-MS Analysis (Total Metals) PE Sample Results The PES recoveries for metals in soil by ICP-MS were scored as within limits by the web-based SPS Web software. Therefore, no data qualifiers were applied to the sample results based on these criteria. Other QA/QC Results Serial dilution % difference was above the acceptance limit for aluminum (18%) in SDG MDBAB7. All aluminum results in SDG MDBAB7 were considered estimated and “J” qualified. Mercury PE Sample Results The PES recovery for mercury was scored as within limits by the web-based SPS Web software. Therefore, no data qualifiers were applied to the sample results based on these criteria. Other QA/QC Results 5/18/23 16:11C231105 TMTL FINAL 05 18 23 1611Page 2 of 29 D.A.R.T.
