In conducting downgradient sampling pertaining to another Superfund site in the area (the PCE/TCE Northeast Contamination site, f.k.a. as the York Northeast Groundwater site), a distinct groundwater contaminant plume in York was discovered by the U.S. Environmental Protection Agency in the fall of 2010. As a result of this discovery, the EPA completed an Abbreviated Preliminary Assessment (APA) for the Site in November 2010. Sampling conducted during the preparation of the APA identified eight residential drinking wells with concentrations of PCE ranging from 9.6 to 32 micrograms per liter (mg/L). Of these wells, one also contained trichloroethene (TCE) at a concentration of 5.9 mg/L. The EPA’s maximum contaminant level (MCL) for both PCE and TCE is 5 micrograms/liter.
