The volatile organic compound (VOC) sample results from the Illinois EPA's recently installed bedrock monitoring well indicate vinyl chloride contamination of the bedrock groundwater between Playfield Cleaners and the former Crestwood PWS well, as predicted by the Illinois EPA's groundwater flow monitoring results. (Please see the Illinois EPA's fact sheet, Update #3, posted at http://www.epa.state.il.us/community-relations/fact-sheets/crestwood-pws/index.html for a discussion of the groundwater flow modeling predictions.) The VOC samples were collected from the bedrock monitoring well on September 17, 2009. Illinois EPA experts believe these data implicate the Playfield Cleaners property as the source of contamination of the former Crestwood PWS Well #1.
