EPA RCRA ID: MD8213822762
The Resource Conservation and Recovery Act (RCRA) is the public law that creates the framework for the proper management of hazardous and non-hazardous solid waste. Corrective action is a requirement under RCRA that facilities that treat, store or dispose of hazardous wastes, or did so in the past, investigate and clean up hazardous releases into soil, groundwater, surface water and air. For more information, and for more information on RCRA-specific terms used on this page, please visit EPA’s umbrella RCRA web page or EPA’s RCRA Corrective Action page.

Cleanup Activities
EPA made its Corrective Action Remedy Decision on August 23, 2018, of "Corrective Action Complete with Controls" at the Adelphi Laboratory Center (ALC), consisting of ‘no further action’ for soil, and for groundwater, implementation of an institutional control prohibiting use of site groundwater for drinking water purposes.
Cleanup Actions or environmental indicators characterizing the entire facility are shown below. This listing, and all the data on this page, come from EPA’s RCRAInfo and are refreshed nightly to this page. For this table, a blank in the Status column could mean the action either has not occurred or has not been reported in RCRAInfo.

Facility Description
Link to a larger, interactive view of the map.
The Adelphi Laboratory Center (ALC) is an active 207-acre U.S. Army research and development Facility located at 2800 Powder Mill Road in Adelphi, Maryland, a suburb of Washington, D.C.
ALC activities have included development of electronic fuses for projectiles (i.e., mortar, artillery, rockets, missiles) and associated electronic technology, research on fluidics and nuclear weapons effects technologies. Operations are conducted on a small or prototype scale rather than full scale production.
Residual or remaining contamination is in groundwater only, in a defined plume located in the eastern area of ALC. The primary contaminant is trichloroethylene (TCE), a dissolved solvent, that was released on the adjacent property, the former Naval Surface Warfare Center, White Oak Detachment, and flowed downgradient in groundwater (GW), impacting ALC GW. GW was actively treated and is monitored for attenuation annually by the U.S. Navy.
Institutional and Engineering Controls at this Facility
Land Use Controls were developed and are implemented by the Navy on the former Navy Site, which includes ALC and the General Services Administration (GSA) properties. On-site GW use is prohibited for drinking water purposes.
Institutional and Engineering Controls help ensure human exposure and groundwater migration are under control at a cleanup facility. Where control types have been reported by states and EPA in EPA’s RCRAInfo, they are shown below. Not all control types are needed at all facilities, and some facilities do not require any controls. Where there are blanks, the control types may not be needed, may not be in place, or may not be reported in RCRAInfo.
