EPA: Vapor intrusion in Ohio suburb more serious

RIVERSIDE, Ohio (AP) — Environmental and health officials say vapor intrusion in a suburban Dayton neighborhood is more serious and widespread than originally believed.

A U.S. Environmental Protection Agency investigation recently expanded to about 365 homes in Riverside as the agency collects air samples to determine how serious vapor intrusion is for homeowners.

Steve Renninger, the EPA on-scene coordinator, tells the Dayton Daily News for a story Friday (http://bit.ly/1pigQ87 ) that screening levels are higher than the agency suspected in December and vapor intrusion is penetrating deeper into the neighborhood.

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 pollution that can make people sick.
