Groundwater contamination by tetrachloroethene and its dechlorination products is present in two partially intermingled plumes in the surficial aquifer near a former dry‐cleaning facility at Site 45, Marine Corps Recruit Depot, Parris Island, South Carolina. The northern plume originates from the vicinity of former above‐ground storage tanks. Free‐phase tetrachloroethene from activities in this area entered the groundwater. The southern plume originates at a nearby, new dry‐cleaning facility, but probably was the result of contamination released to the aquifer from a leaking sanitary sewer line from the former dry‐cleaning facility. Discharge of dissolved groundwater contamination is primarily to leaking storm sewers below the water table. The strong influence of sanitary sewers on source distribution and of storm sewers on plume orientation and discharge at this site indicates that groundwater‐contamination investigators should consider the potential influence of sewer systems at their sites.
