EPA added the Smithtown Groundwater Contamination site in Smithtown, New York (Suffolk County) to the Superfund National Priorities List on January 19, 1999, because of harmful chemicals found in residential drinking water wells. Perchloroethylene (PCE) contaminated ground water which impacted drinking water in Smithtown, the villages of Nissequogue and Head of the Harbor and the hamlet of St. James. About 500 homes are in the immediate area of vicinity of the site. PCE, a solvent used in dry cleaning and metal cleaning, is considered a potential human carcinogen by the U.S. Department of Health and Human Services.

EPA is cleaning up the site in two phases: Immediate actions to provide alternate water supplies and a long-term remediation of contaminants at the site. EPA connected affected residents to public water supplies and provided bottled water. EPA is also conducting long-term ground water and surface water monitoring and controls to restrict the use of contaminated water. During its research, EPA could not identify the source of the contamination or a plume reaching ground water.
