EPA is investigating a pollution issue called “vapor intrusion” in the Valley Pike neighborhood of Riverside, Ohio. Vapor intrusion occurs when underground pollutants give off dangerous gases that can rise up through the soil and seep into buildings through foundation cracks and holes, causing unsafe indoor air pollution. The EPA removal action is scheduled to begin in December 2013.

EPA is working with Ohio Department of Health, Ohio EPA, and Public Health – Dayton and Montgomery counties. In its preliminary sampling, EPA and the other agencies conducted several tests and found some elevated levels of chemical vapors. EPA now wants to do more sampling to check the extent of the contamination.

EPA and Ohio EPA conducted a Vapor Intrusion investigation in July 2013 including groundwater, soil gas, sub-slab and indoor air sampling.  On May 9, 2013, the Ohio EPA requested assistance from EPA at the Valley Pike VOC Site in Riverside, Ohio. Ohio EPA noted potential hazards posed to nearby residences and businesses from subsurface migration of solvent vapors into indoor air. Chemicals of concern include PCE and TCE.
