# Tarawa Terrace Reports

Recommend on FacebookTweetShareCompartir

Results for Tarawa Terrace—based on information gathering, data interpretations, and water-modeling analyses — show that former Marines and their families who lived in Tarawa Terrace family housing units during the period November 1957 through February 1987 received drinking water primarily contaminated with the dry-cleaning solvent tetrachloroethylene (PCE). Levels of PCE in the drinking water during this period exceeded the amount currently allowed by the Environmental Protection Agency (EPA) under the Safe Drinking Water Act.

Exposure to PCE-contaminated drinking water occurred because PCE leaked into groundwater that supplied the Tarawa Terrace drinking water system from a dry-cleaner located outside the Camp Lejeune military base. In 1987, the military base shut down the Tarawa Terrace water treatment plant because of PCE contamination of the drinking water.
