THE FORT DETRICK FIVE-YEAR REVIEW HAS EVALUATED CLEANUP AT AREA A BUILDING 568 TCE SPILL SITE, AREA B LANDFILLS AND
AREA C WASTE WATER TREATMENT PLANT (WWTP)
FORMER ASH DISPOSAL AREA (FADA)
The U.S. Army has completed the Five-Year Review (FYR) process required under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) for the following environmental restoration sites at Fort Detrick:
Area A (FTD 66) – Area A Groundwater: Building 568 Trichloroethylene (TCE) Spill
Remedy: 1) TCE plume containment such that contaminant concentrations above the EPA Maximum Contaminant Level (MCL) remain within Fort Detrick property and 2) groundwater monitoring of the plume.
Area B Landfills: Area B-11 (FTD 49), Landfill B-2 (FTD 50), Landfill B-3 (FTD 51), Area B-6 (FTD 69), Area B-8, B-18 and Trenches north of B-8 and Area B-18 (FTD 70), Area B-10 and B-Grove (FTD 71)
Remedy: Landfill Cap and Land Use Control, which includes installation and maintenance of a low permeability cap to contain the waste in place and minimize infiltration of rainwater, to prevent exposure to contaminated soils and wastes.
Area C (FTD 54) – Area C WWTP Former Ash Disposal Area (FADA)
Remedy: Institutional Control (IC) to prevent human contact with residual ash material that is buried at the site.
The purpose of a FYR is to determine if the remedy selected in the Decision Document for each of the above listed sites is, and will continue to be, protective of human health and the environment. The remedy for Area A was judged protective. The remedies for Areas B and C were evaluated as short-term protective. While there are no issues with current protectiveness at Area B, additional lines of evidence which will help evaluate remedy performance are being undertaken, as described in the Cap Inspection and Monitoring Work Plan, 2016. At Area C WWTP FADA, the recommended action in the FYR to achieve a “protective” determination, administratively increasing the IC boundaries to cover all areas which present an unacceptable risk to human health and the environment, has been completed.
These FYRs do not include the ongoing investigation that is currently being conducted for the Area B groundwater, which will become part of a future Five-Year Review process, once the cleanup remedy has been implemented. If you are interested in an update on the Area B groundwater investigation, please attend the next Fort Detrick Restoration Advisory Board (RAB) meeting.
