The Camp Lejeune Military Res. (USNavy) site includes an active U.S. Navy (Navy) base. The base opened in 1942. The EPA placed the site on the National Priorities List (NPL) in 1989 because of contaminated ground water, sediment, soil and surface water resulting from base operations and waste handling practices. The 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.
