The 236 square-mile Camp Lejeune Military Res. (US Navy) site is located in Jacksonville, North Carolina. The site includes an active U.S. Navy (Navy) base. The base opened in 1942. EPA placed the site on the Superfund program�s National Priorities List (NPL) in 1989 because of contaminated groundwater, sediment, soil and surface water resulting from base operations and waste handling practices. EPA, the North Carolina Department of Environment and Natural Resources (NCDENR), and the Navy have investigated site conditions and taken steps to clean it up to protect people and the environment from contamination. Site contamination does not currently threaten people living and working near the site. By conducting site investigations, cleanup activities and required Five-Year Reviews, and placing institutional controls on the site property, EPA, NCDENR and the Navy continue to protect people and the environment from site contamination.
