Hazardous Waste Cleanup: United States Army Garrison in Fort Belvoir, Virginia

On this page:

In September 2004, the Virginia Department of Environmental Quality (VDEQ) issued U.S. Army Garrison, Ft. Belvoir, Main Post (Main Post) a Resource Conservation and Recovery Act (RCRA) Hazardous Waste Permit. The Permit required the Army to conduct RCRA Facility Investigations (RFIs) for possible releases of hazardous waste/constituents at any Solid Waste Management Units (SWMUs) and Areas of Concern (AOC) identified on the Main Post. Over 200 SWMUs and AOCs were identified on the Main Post.

Cleanup Status

SWMUs and AOCs include inactive landfills, storage areas, wastewater treatment plants and other areas of past contaminant releases. Ft. Belvoir closed many SWMUs under VDEQ oversight prior to the 2004 VDEQ Permit. EPA reviewed the data and concurred with the closures, thereby removing 130 SWMUs and other units from the list of units for further investigation. Currently, Ft. Belvoir has addressed almost all of the remaining SWMUs and AOCs by investigating soil, groundwater and landfill gas, delineating extent and types of contamination, if any, or finding that no further action or remediation is necessary.

In August 2015, VDEQ renewed the RCRA Permit which includes only 15 SWMUs needing further investigation. Investigations will continue under VDEQ oversight.

Contaminants at this Facility

Contaminants have been found in specific Solid Waste Management Units (SWMUs) in soil, groundwater and in one or two locations, sediment. Groundwater contamination is the primary media affected by previous chemical releases. Contaminants found in groundwater are primarily petroleum compounds and chlorinated solvents. Contamination to soil includes petroleum compounds, solvents, and metals. Polychlorinated biphenyl (PCBs) in soil were found in a few SWMUs. Soil with contamination exceeding EPA’s acceptable risk to human health has been excavated and removed and contaminated groundwater in limited areas is under active treatment. Human exposure to any remaining contamination is monitored and controlled by implementing Institutional Controls.

Institutional and Engineering Controls at this Facility

The Main Post is using Land Use Controls (LUCs) to prevent human exposures to any remaining contamination in soil, groundwater, landfills and other structures at the Facility. LUCs restrict current and future land use to non-residential, prohibit use of groundwater as a drinking water source, and monitoring of landfill gases and covers. The LUCs are incorporated into the Facility's Master Plan and geographical information system (GIS) layers. Ft. Belvoir reports to VDEQ and US EPA annually on LUC implementation.
