(Terracon) is pleased to submit this letter summarizing historical water supply well sampling results for select properties in the vicinity of the former Albemarle Dump (Site). This work was completed in general accordance with Terracon’s work plan for Task Order 571RA-13a, 18a-c, and 19a-d, dated August 30, 2023, and North Carolina Department of Environmental Quality (NCDEQ) Approval of Work Plan and Cost Proposal dated August 31, 2023. Site Description The Site is located on Nanny Drive in Albemarle, North Carolina, approximately 2 miles northeast of downtown Albemarle, North Carolina and is primarily wooded and cleared land with a stream bisecting the parcel from west to east. Three discrete Waste Disposal Areas (WDA A, B and C) occupy 10.47 acres of the 77.16-acre site parcel (Stanly County Parcel No. 653901079384) owned by Ms. Ruth A. Page (AECOM, 2021). The area surrounding the site is a mix of rural and residential properties, for which public water is not available. As of 2015, 38 water supply wells have been identified by prior consultants within 1,000 feet of the Site. Additional properties have been developed since that time, and are presumed to have water supply wells. Contaminates associated with the Site have historically been identified in groundwater, including groundwater from five downgradient water supply wells (Well 1, 3, 12, 13 and 28). The five water supply wells have Point-of-Entry (POE) filtration systems. The POE systems generally consist of a sediment filter, two Granulated Active Carbon (GAC) vessels, and an ultraviolet (UV) filter. Water samples for the POE filtration systems are collected from the influent, mid-point, and effluent ports of the GAC vessels, which are after the sediment filter and before the UV Albemarle Dump – NONCD0000571 Remedial Action Phase 571RA-19d | Albemarle, NC March 19, 2024| Terracon Project No. 71237029A Facilities | Environmental | Geotechnical | Materials 2 filter. Information about the location and installation dates of the POE systems is summarized as follows: Well ID Address Installation Date Well 1 32311 Nanny Drive 5/19/2011 Well 3 32311 Nanny Drive 5/19/2011 Well 12 29387 Pennington Road 2/28/2012 Well 13 31796 Old Herlocker Road 10/4/2011 Well 28 34512 Tiffany Drive 1/3/2014 In addition to the POE systems an additional 33 water supply wells without POE systems within 1,000 feet of the Site have been identified. Historical data collected has not warranted the installation of POE systems on these wells, but they are sampled, pending permission from the property owners, for monitoring on an annual or bi-annual basis. Water supply well information is summarized in Table 1, and locations are depicted on Figure 1. Terracon reviewed existing POE and potable well sampling reports for the Site and surrounding properties. This data compilation includes prior reports available on Laserfiche, those provided by the Unit PM, and the recent annual sampling activities completed in November and December 2023, as part of Task Order 571WS-19a and 571WS-19b. Pertinent information from these reports are included as Appendix A. Tables summarizing highest detections for the POE system wells is included as Table 2, and water supply wells as Table 3. This information is submitted to the Unit PM for review and future remedial investigative and planning purposes. If you have any questions, please contact Michael Dail at (984) 202-4055.
