Health Consultation: Vapor Intrusion of PCE in a Residential Community, Former Crescent Cleaners, Evansville, Vanderburch County, Indiana. EPA Facility ID: IND981783616

摘要

The Region 5 Agency for Toxic Substances and Disease Registry (ATSDR) and the Indiana State Department of Health (ISDH) was asked by the Indiana Department of Environmental Management (IDEM) to evaluate possible health effects from exposures to elevated levels of perchloroethylene (also known as PCE, tetrachloroethylene, or PERC) detected in some Evansville, Indiana, residential houses. While investigating groundwater contamination associated with the Former Crescent Cleaners site in Evansville, Indiana, IDEM detected levels of PCE in groundwater up to 23,000 parts per billion (ppb) with groundwater depths at about 35 feet. In one soil sample, PCE was detected in concentrations as high as 9,500,000 ppb. Since the soil in this area is particularly sandy, IDEM evaluated the potential for PCE vapors from the groundwater infiltrating into nearby homes and businesses. IDEM continues to conduct additional sampling studies of contamination of indoor air, soil, and groundwater to characterize the extent of the PCE plume.
