Dear Mr. Berger: As authorized by your acceptance of ECS Southeast, LLP (ECS) Task Authorization Request
(TARs) No. 3 dated April 6, 2020, ECS has completed the Letter Report for the above referenced site. Included in this report is a description of the field activities, the results obtained, and our conclusions and recommendations.
PROJECT UNDERSTANDING
The site is located at 983 US Highway 21, State Road, Surry County, North Carolina (Figures 1
and 2). Based on information provided to ECS, four 4,000-gallon gasoline underground storage tanks (USTs) were removed from the site in October 1992. During closure activities, free
product was observed flowing into a test pit that was excavated to a depth of approximately 19 feet below the ground surface. Petroleum hydrocarbons were detected in soil samples collected from the UST basin and dispenser areas. On February 20, 2018, ECS collected groundwater samples from monitoring wells MW-2, MW-3, MW-4, and MW-5 and water supply well WSW-5. Laboratory analysis of groundwater samples collected from monitoring wells MW-2 and MW-3 detected multiple targeted
compounds greater than their respective North Carolina 2L Groundwater Quality Standard (NC2LGWQS); however, the concentrations did not exceed their respective Gross Contamination Levels (GCLs). Laboratory analysis of the groundwater sample collected from monitoring well MW-4/RW-4 detected benzene greater than its NC2LGWQS, but less than its
GCL. Laboratory analysis of the groundwater sample collected from monitoring well MW-5 did not detect targeted compounds greater than the laboratory detection limits. No free product was observed in the site monitoring wells. MTBE was detected in the sample collected from water
supply well WSW-5 at a concentration greater than its NC2LGWQS, but less than its GCL. ECS collected groundwater samples from monitoring wells MW-2, MW-3, MW-4, and MW-5 and water supply well WSW-5 on December 12, 2019. Review of the laboratory analytical
report of groundwater samples collected from monitoring wells MW-2 and MW-3 indicated multiple targeted compounds greater than the NC2LGWQS; however, the concentrations were
