Scientific evidence of health problems from past contamination of drinking water at Camp Lejeune is limited and unlikely to be resolved with further study

WASHINGTON -- Evidence exists that people who lived or worked at Camp Lejeune Marine Base in North Carolina between the 1950s and 1985 were exposed to the industrial solvents tricholorethylene (TCE) or perchloroethylene (PCE) in their water supply, but strong scientific evidence is not available t...

Contaminated drinking water at Camp Lejeune -- Report release June 13

Two chemicals -- trichloroethylene (TCE) and tetrachloroethylene (PCE) -- found to have contaminated drinking water at Marine Corps Base Camp Lejeune from the 1950s to 1985 have been linked to certain diseases and disorders, including various cancers. A new report from the National Research Counc...
