How did the Marine Corps become aware of drinking water problems at Camp Lejeune?
The Marine Corps first learned of the problems in 1982, when sampling revealed that the drinking water distribution system at Hadnot Point contained unidentified substances. The source was unknown at that time, and subsequent samplings were inconclusive as to the nature of the substances. In the early 1980s, the EPA established National Primary Drinking Water Standards, which included standards for acceptable levels of many chemicals. In May 1982, Camp Lejeune conducted compliance testing of its water system and found the volatile organic compounds (VOCs) trichloroethylene (TCE) and tetrachloroethylene (PCE) in the Hadnot Point and Tarawa Terrace water distribution systems. Testing of water for compliance continued until June 1984. In June 1984, EPA proposed standards for TCE and PCE in water systems. Camp Lejeune then began to sample for TCE and PCE at its water wells shortly thereafter, and in October 1984, began to shut down those that were found have levels exceeding the new propos
