2.0 Current Activities
2.1 Operations
2.1.1 Narrative
During a vapor intrusion assessment conducted in March 2015 by the EPA for the PCE Former Dry Cleaners Site, the EPA discovered another former dry cleaner site (PCE Chestnut Street) to the west of the PCE Former Dry Cleaners Site. The levels of PCE vapors found in buildings at the Site present a significant health threat due to inhalation hazards.
2.1.1.1 Current situation
During the week of November 10, 2015, four vapor mitigation systems were installed in properties at the site. Vapor mitigation systems were installed in these properties because subslab and/or indoor air sample results were above maximum contaminant levels.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
PRPs have not been identified.
2.1.4 Progress Metrics
