Letter Health Consultation: Evaluation of Indoor Air Results for Homes Located in the Proximity of the Site, Chem Fab Site, Doylestown, Bucks County, Pennsylvania, February 11, 2013.

摘要

During 2010 and 2011 the U.S. Environmental Protection Agency (EPA) performed a vapor intrusion investigation for homes in the proximity of the Chem Fab Superfund Site in Doylestown, Pennsylvania. Vapor intrusion is the movement of gas vapors into indoor air of structures located over a subsurface plume of contamination. The purpose of EPAs investigation was to assess whether site-related volatile organic compounds (VOCs) are migrating from the property and affecting the nearby community. As part of this investigation, EPA collected indoor and outdoor ambient air samples from homes located near the former Chem Fab facility.
