Camp Lejeune water contamination

The Camp Lejeune water contamination problem occurred at Marine Corps Base Camp Lejeune in Jacksonville, North Carolina, from 1953 to 1987. During that time, United States Marine Corps (USMC) personnel and families at the base — as well as many international, particularly British, assignees — bathed in and ingested tap water contaminated with harmful chemicals at all concentrations from 240 to 3,400 times current safe levels.
