The Site is located in the vicinity of Old Wilmington Road in West Caln Township, Chester County, Pennsylvania and consists of multiple investigation areas and multiple overlapping plumes of groundwater contamination.
The Site is currently on the Superfund National Priorities List (“NPL”) and in the Remedial Investigation (“RI”) stage. Several houses in the area had carbon filtration systems installed during a previous Removal Action due to high volatile organic compounds (“VOCs”) in their wells.
November 2017 validated results for two private wells came back with elevated metals (manganese and lead). EPA toxicologists concluded that based on the levels found, immediate intervention to interrupt the exposure pathway was recommended for the two wells. On April 24, 2018, after consulting with the EPA Remedial Project Manager and EPA toxicologists, and evaluating the factors contained in Section 300.415 of the NCP, OSC Rovira determined that conditions at the Site posed a significant threat to public health, welfare or the environment and initiated response activities pursuant to Section 104 of CERCLA to mitigate the threat.
