ABSTRACT (Maximum 200 words) The former U.S. Army Vint Hill Farms Station (VHFS) closed in September, 1997, pursuant to the Base Realignment and Closure (BRAC) program. As of May 22, 2003, all of the former VHFS property had been transferred to either the Vint Hill Economic Development Authority (VHEDA) or Fauquier County. Area Requiring Environmental Evaluation (AREE) 34 at the former VHFS has been identified as a location where chlorinated volatile organic compound (VOC) groundwater contamination is present in the saturated overburden material and underlying bedrock aquifer. A Remedial Investigation (RI) and a Supplemental RI have been conducted at AREE 34. Based on the results of these investigations, it was determined that further investigation was required to better define the upgradient extent of the groundwater contamination in the overburden material and to refine the conceptual site model (CSM). The Further Delineation of VOC Contamination in Overburden (FDVCO) investigation was performed to address these data gaps using the U.S. Environmental Protection Agency’s (USEPA’s) dynamic Triad Approach. This FDVCO – Summary Report (FDVCO-SR) presents the procedures for conducting the FDVCO investigation, and the associated investigation findings. 14. SUBJECT TERMS 15.
