Vapor Intrusion occurs when residual contamination in soil vaporizes and travels into homes, buildings and other enclosed areas. Vapor Intrusion is an increasing area of Public and Regulatory Concern as a new risk pathway for exposure to contaminants.
This series of stories from the Dayton Daily News demonstrates the level of concern and challenges that regulators and the exposed community faces with this newly identified threat. I call it newly identified because it has always been present in areas where organic contaminants are left behind in soil beneath or near structures. It is only now becoming an issue that affects redevelopment and construction.
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 Agencyinvestigation 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.
