Superfund Site Profile
The 6,400-acre Patuxent River Naval Air Station (NAS) site is located in St. Mary’s County, Maryland, at the confluence of the Patuxent River and the Chesapeake Bay on a peninsula known as Cedar Point. Operation of landfills and other areas contaminated soil, sediment, groundwater and surface water with hazardous chemicals. The landfills received solid and hazardous wastes such as sewage treatment plant sludge, cesspool wastes, spent oil absorbents, paints, antifreeze, solvents, thinners, pesticides and photo lab wastes. Cleanups are complete at some areas within Patuxent River NAS. Operation and maintenance activities at these areas are ongoing. Investigations and remedy selection activities continue at the remaining areas.
