Background

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.

Site Updates

November 2014

The U.S. Environmental Protection Agency has been busy sampling residences near the Valley Pike Superfund site and installing vapor abatement systems on structures that need them. The VAS is very similar to a radon removal system common to many Midwestern houses. The process includes installing a subslab or crawl space depressurization system, sealing cracks in walls and basement floors and includes air sampling to verify the VAS is working properly. Since December 2013, EPA sampled over 271 residences and installed 70 VAS.

Based on recent residential sampling data, EPA has again expanded the area of concern in the Valley Pike site farther west to Sagamore Avenue. 

Residents have until March 30, 2015, to turn in a signed access agreement to have their property sampled.

U.S. EPA is still sampling at no cost homes that may have vapor intrusion seeping in their crawl spaces or basements. Residents are encouraged to stop by the EPA office at 2049 Harshman Road to sign a permission or access agreement for this free service.
