The new Vapor Intrusion Considerations for Redevelopment Primer from EPA’s Brownfields and Land Revitalization Technology Support Center (BTSC) is now available electronically at http://www.brownfieldstsc.org/pdfs/BTSC%20Vapor%20Intrusion%20Considerations%20for%20Redevelopment%20EPA%20542-R-08-001.pdf

Vapor intrusion is an exposure pathway - a way that people may come in contact with environmental contaminants. Vapor intrusion exposes building occupants to potentially toxic levels of vapors when volatile chemicals (those that readily evaporate) present in contaminated soil or groundwater emit vapors that migrate into overlying buildings. It is similar to the more familiar problem of radon, a gas that is emitted naturally from soil and bedrock and enters buildings through cracks and openings in the foundation and through porous building materials.

This primer is designed for land revitalization stakeholders concerned about vapor intrusion, including property owners, municipalities, and real estate developers. It provides an overview of the vapor intrusion issue and how it can affect redevelopment. It also summarizes techniques for quickly and cost effectively assessing the potential for vapor intrusion, as well as techniques for mitigating it.
