You may think that only those who drank the water at Camp Lejeune were exposed to the toxic chemicals in the water, which included trichloroethylene (TCE) and perchloroethylene (PCE). However, according to a 2009 National Research Council report, additional methods of exposure included washing dishes, showering, and bathing, as PCE and TCE in hot water can be inhaled after evaporating. Two water systems at Camp Lejeune were contaminated with toxic chemicals: the Hadnot Point system and the Tarawa Terrace system. The Tarawa Terrace system was primarily contaminated with PCE by an off-base dry cleaner. The Hadnot Point system was contaminated with multiple chemicals, including TCE and PCE, by multiple sources.
