Letter Health Consultation: Eastwick Community Indoor Air Evaluation. LDCA Site Clearview Landfill (Lower Darby Creek Area Superfund Site), Philadelphia, Delaware and Philadelphia Counties, Pennsylvania, October 1, 2012.

摘要

In 2010 and 2011, the US Environmental Protection Agency (EPA) performed a vapor intrusion investigation to assess whether landfill gases, including volatile organic compounds (VOCs), from the Clearview Landfill (the site) are impacting the nearby community. Vapor intrusion is the movement of gas vapors into indoor air of structures located over groundwater contamination. Indoor air, sub-slab soil gas, and outdoor ambient air samples were collected from homes and a recreational center located near the former Clearview Landfill. The Pennsylvania Department of Health (PADOH) reviewed the EPA sampling data, as part of the site remedial investigation/feasibility study (RI/FS) and prepared this letter health consultation (LHC). PADOH evaluated whether VOCs detected in the indoor air pose a public health threat to area residents and visitors. The purpose of this LHC is to summarize PADOHs evaluation and to provide relevant public health conclusions and recommendations.
