Current Site Status

The Army Material Command has transferred 668 acres of the 701-acre facility to the Vint Hill Economic Development Authority (VHEDA). The VHEDA currently has leases with 23 tenants that range from a logistics engineering and information technology firm, to the new headquarters for the Federal Aviation Administration. The facility will accommodate over three million square feet of innovative technology, residential areas, research and development, and light industrial uses at its completion. EPA has reviewed and commented on five decision documents for Areas Requiring Environmental Evaluation AREEs that will be included in the second transfer of the property. The army discovered an additional AREE in December 2000 which has been investigated and would require a long-term monitoring program with a five-year review. The second transfer, which took place in July 2001, consisted of 11 parcels that cover approximately five acres. Vint Hill completed it's five year review in October 2005 and is continuing with monitoring. The AREE 34 Decision Document was signed in March 2007. At issue was the frequency and analysis of Army-related contamination in production and bedrock monitoring wells. The Army and VADEQ have agreed to the following: 1) Quarterly groundwater sampling until the Remedial Action Objectives outlined in the Decision Document are reached or the VADEQ concurs with an alternative monitoring frequency, 2) The Army will install a carbon filtration unit on production well #1 if the yearly average of any site related VOCs exceeds one-half the MCL for that particular VOC, 3) ; when the yearly average of all site related VOCs falls below the respective MCLs the carbon filtration unit operation at production well #1 will cease. Vint Hill continues to monitor the groundwater as per the provisons of the Decision Document for AREE 34. The next quarterly report is scheduled to be submitted in July 2010.

Site Description

Vint Hill Farms Station (VHFS) is a 701-acre facility located in Faquier County in the city of Warrenton. During World War II, VHFS served as a refitting station for units returning from combat before overseas deployment. In 1961, the U.S. Army Electronic Material Readiness Activity was moved to VHFS. In 1973, U.S. EPA took over operation of the photographic interpretation center from the Defense Intelligence Agency which was renamed the Environmental Photographic Interpretation Center (EPIC). The Army Material Command (AMC) became the major command for VHFS in 1987. VHFS is currently under the Major Subordinate Command of Communications-Electronics Command (CECOM) and was named to the Base Realignment and closure (BRAC) list in 1993.

The Army Material Command signed the Finding of Suitability to Transfer (the document which summarizes site conditions and officially documents the property transfer) on September 24, 1999. The current on-base population including contractors, emergency personnel and employees of the new engineering and technology corporations is approximately 300. The facility's major command transferred its operations to Fort Monmouth, N.J.

NPL Listing History
This is a non-NPL Site.

Threats and Contaminants

Several remediation projects have been completed at the facility. The hazardous substances and other contaminants of concern detected at VHFS included lead, TPH, chlordane, DDT, mercury, silver, PAH, PCB, dioxin/furans, benzo(a)pyrene and selenium. This contamination had been found in soil, surface water and sediment.

Contaminant descriptions and risk factors are available from the Agency for Toxic Substances and Disease Registry, an arm of the CDC.

Cleanup Progress

With the exception of those projects that require long-term monitoring, and those that are under the auspices of the VADEQ state RCRA program, the facility has completed the remediation projects, that were required for the transfer. Remediation projects at the facility included excavation of organic contaminated soil, dredging and solidifying contamination at an onsite tributary, destruction of pesticide contaminated buildings and capping of an on-site landfill. There were also several proposed plans and decision documents that were reviewed by the EPA and the VADEQ. With the agreements reached on the AREE 34 DD the DD was signed in March 2007.
