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.

December 2013

EPA held a public meeting at Stebbins High School, 1900 Harshman Road in Riverside to discuss the environmental situation in the Valley Pike neighborhood. At the meeting, EPA staff presented the recent sampling results and discussed additional sampling. The removal action included sampling additional residences for Vapor Intrusion. EPA asked the public to assist EPA efforts by signing access forms from property owners and tenants to take samples and protect a building from vapor intrusion if necessary. Since the meeting 50% of the access agreements were signed. EPA is scheduling times for testing for those residents who signed.

An office has been set up at 2049 Harshman Road, Riverside for the general public to visit and sign the permission agreements or who may have concerns about the ongoing investigation.

The EPA VOC site phone number is 937-237-7530. The office will be staffed from 9am to 4pm Monday through Friday.
