Main Plant Groundwater Sampling Report – Badin Business Park Facility - Badin, NC; September 2018 1 1.0 INTRODUCTION The April 28, 2017 Investigative Work Plan for the Phase 4 and 5 Corrective Measures Study, Alcoa/Badin Landfill, and Former Ball Field (Work Plan) was developed as a guidance document in support of sampling and investigative activities at the Badin Business Park LLC, formerly known as the Alcoa Badin Works facility. The Work Plan was prepared following receipt of the North Carolina Department of Environmental Quality (NCDEQ) January 23, 2017 correspondence concerning the review of Phase 4 and 5 of the Corrective Measures Study (CMS), the Expanded Pre-CERCLIS Screening Assessment (EPSA) for the Former Ball Field, and the Site Inspection Report (SIR) for the Alcoa/Badin Landfill. NCDEQ determined that further evaluation was warranted and requested that a demonstration be made that identified items had been evaluated or prepare a work plan to evaluate those items. Select items were addressed in a March 3, 2017 written response and in a meeting with NCDEQ on March 28, 2017. On April 2, 2018, the Work Plan was revised incorporating requirements from the January 31, 2018 conditional approval letter and the instream monitoring study requirements of the September 29, 2017 Final NPDES Permit, Condition A. (8.). Implementation of the Work Plan began in April 2018. The approach for investigative activities was developed based on information obtained from site reconnaissance, previous investigations, and remedial activities conducted at the facility. The Work Plan was organized by the tasks:  Task 1 – Alcoa/Badin Landfill  Task 2 – Main Plant Area  Task 3 – Former Ball Field Area The scope of work for each of the tasks was summarized in Section 2 of the Work Plan. The following report details activities in support of Task 2, investigations at the Main Plant Area. 1.1 Site Overview The facility is located on State Highway 740 within the Town of Badin, North Carolina, and occupies approximately 123 acres of land. Production at the Badin Works facility began in 1916 and continued through 2002. Principal products once manufactured at the facility included carbon cathodes and anodes, continuous cast sheets, and specialty metals. The facility was permanently closed in 2010 and several buildings were razed in 2012. In 2016, the legal owner and operator of the facility transferred from Alcoa Inc. to the Badin Business Park LLC, a subsidiary Alcoa Corporation (Alcoa). In March 2001, a RCRA Investigation (RFI) report was submitted for the facility. The RFI identified trichloroethene (TCE) as a constituent of concern in groundwater in the northeast corner of the former main plant area. As part of the January 23, 2017 correspondence concerning the review of Phase 4 and 5 of the CMS, the NCDEQ requested additional groundwater sampling from newly installed monitoring well MW- 110. To satisfy the NCDEQ request, the April 2, 2018, Work Plan outlined activities to meet NCDEQ’s objective. ENVIRONEERING, INC. Main Plant Groundwater Sampling Report – Badin Business Park Facility - Badin, NC; September 2018 2 1.2 Scope of Work To address the objective of determining if TCE is present in monitoring well (MW-110) and to update the TCE groundwater concentration data at the Main Plant area, groundwater samples were collected from four monitoring wells (MW-4, MW-9, MW-16, and MW 110). The groundwater samples were analyzed for volatile organic compounds (VOCs) including TCE. Results from the completion of the scope of work are detailed below. ENVIRONEERING, INC. Main Plant Groundwater Sampling Report – Badin Business Park Facility - Badin, NC; September 2018 3 2.0 SAMPLING RESULTS To complete the objectives concerning the Main Plant area, groundwater samples were collected from monitoring wells MW-4, MW-9, MW-16, and MW-110 on July 9 and 10, 2018. Monitoring well locations are presented on Figure 2-1. The laboratory results for this sampling event are summarized in the following tables:  Table 2-1 Field Data from July 2018 Sampling Event; and  Table 2-2 Groundwater Analytical Results from July 2018 Sampling Event  Table 2-3 Field Blank Analytical Results from July 2018 Sampling Event. A copy of the laboratory analytical report and chain-of-custody form for the groundwater sampling event is provided in Appendix A. 2.1 Sampling Technique The sampling technique employed during the sampling events consisted of low flow purging and sampling of the well following Low Stress (Low Flow) Purging and Sampling Procedure for the Collection of Groundwater Samples from Monitoring Wells guidance issued by USEPA. This guidance was based on the April 1996 Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures by Robert W. Puls and Michael J. Barcelona. Sample collection, shipment, and decontamination followed procedures outlined in the April 2, 2018 Work Plan. After purging, water samples were then collected for laboratory analysis. Samples were placed in clean, laboratory-provided, 40 milliliter glass vials, and immediately placed on ice to preserve their physical and chemical integrity. Prior to shipment, the samples were repacked in an ice-packed cooler with chain- of-custody documentation and dropped off at the analytical laboratory via courier the day after collection. 2.2 Field Parameters Field parameters (pH, temperature, conductance, dissolved oxygen, and oxidation-reduction potential) were measured and recorded during the groundwater sampling event. Units of pH were observed to range from 6.73 to 7.63, which is consistent with historical data. With the exception of an outlier at well MW-4 (23.93°C), temperature ranged from 19.33°C to 20.69°C. Conductance ranged from 0.146 mS/cm to 0.386 mS/cm. Dissolved oxygen was observed at concentrations of 0.56 mg/L, 0.64 mg/L, 5.4 mg/L and 5.51 mg/L for MW-110, MW-9, MW-16, and MW-4, respectively. 2.3 Analytical Results Recent groundwater sampling data indicates that only TCE was detected at concentrations exceeding the 15A North Carolina Administrative Code (NCAC) 2L groundwater standard in monitoring wells (MW-4, MW-9, MW-16, and MW-110). Monitoring well MW-9 contained concentrations of 1,1-dichloroethene and cis-1,2-dichloroethene above laboratory detection limits, however the concentrations were below the ENVIRONEERING, INC. Main Plant Groundwater Sampling Report – Badin Business Park Facility - Badin, NC; September 2018 4 15A NCAC 2L groundwater standards. No other constituents were detected at concentrations above laboratory detection limits in any of the monitoring wells sampled. Monitoring well MW-4 is located within the fenced boundary of the facility and has exhibited a downward trend in concentration of TCE (0.0085 milligrams per liter (mg/l)) since December 2011 (0.040 mg/l). Monitoring well MW-9 is located downgradient of MW-4, and also has exhibited decreasing concentrations of TCE between December 2011 (0.086 milligrams per liter (mg/l)) and July 2018 (0.0661 mg/l). Monitoring well MW-16 is located downgradient of MW-9 and has exhibited slightly decreasing concentrations of TCE between December 2011 (0.019 milligrams per liter (mg/l)) and July 2018 (0.0086 mg/l). Monitoring well MW-110 is located downgradient of MW-16 and contained a concentration of TCE (0.0065 mg/l) slightly above the 15A NCAC 2L groundwater standard (0.003 mg/l). 2.4 Field Blanks One trip blank was analyzed as part of this project. The trip blank was prepared prior to the sampling event in the actual sample containers and was kept with the groundwater samples throughout the sampling event. The trip blank was packaged for shipment with the groundwater samples and sent for analysis Results are summarized in Table 2-3. No constituents were detected at concentrations above laboratory detection limits in the trip blank. One equipment blank was analyzed as part of this project. The equipment blank was prepared by running analyte free distilled water through groundwater sample collection equipment (pump) after decontamination and placing it in the appropriate sample containers for analysis. Results are summarized in Table 2-3. Chloromethane was the only analyte detected in the equipment blank and is within the estimated result range. It is not believed that this single analyte at a low level will have any negative effects on the field sample results and may be either a laboratory contaminant or from the source water used to collect the equipment blank. None of the field samples had detectible levels of chloromethane. ENVIRONEERING, INC.

Main Plant Groundwater Sampling Report – Badin Business Park Facility - Badin, NC; September 2018 9 3.0 CONCLUSIONS To address the objective of determining if TCE is present in monitoring well (MW-110) and to update the TCE groundwater concentration data at the Main Plant area, groundwater samples were collected from four monitoring wells (MW-4, MW-9, MW-16, and MW 110). The groundwater samples were analyzed for volatile organic compounds (VOCs) including TCE. Results of Site activities indicated that since the completion of the CMS, concentrations of TCE in in all recently sampled wells decreased, thus indicating that the constituent plume does not appear to be expanding. One monitoring well, MW-110, was installed after completion of the CMS, and contained a concentration of TCE slightly above the 15A NCAC 2L groundwater standard. Results from this groundwater sampling event will be incorporated into a revision to the Corrective Measures Study. The revised Corrective Measures Study will reference the current risk-based remediation standards under NCGS 130A, Article 9, Part 8 and guidance included on the Division of Waste Management website. Should the use of risk-based remediation continue to be recommended as a corrective action alternative, Section 6.3 will be revised to allow for developing site-specific remediation standards to achieve compliance without undue risk to human health and to the environment based upon the present or currently planned future use of the property.
