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
EPA collected confirmation indoor air samples from properties where vapor mitigation systems have been installed, and indoor air samples from properties with no vapor mitigation system the weeks of May 9 and June6, 2016. No sample results exceeded EPA Removal Action Levels.
