Groundwater Monitoring Activities at Department of Energy Facilities
As a result of activities associated with the production of defense-related nuclear materials, about 600 billion gallons of groundwater have been contaminated at Department of Energy (Department) facilities located throughout the United States. The majority of the contamination is located at the Hanford Reservation, Savannah River Site, Idaho National Engineering and Environmental Laboratory, Los Alamos National Laboratory, Oak Ridge Reservation, and Rocky Flats Environmental Technology Site. The contaminants include solvents, fuels, explosives, metals, and radioactive materials.
