Brownfields Technology Primer: Vapor Intrusion Considerations for Redevelopment (PDF) Exit(49 pp, 1.2MB, About PDF)
The Brownfields and Land Revitalization Technology Support Center has developed this primer for land revitalization stakeholders concerned about vapor intrusion, including property owners, municipalities, and real estate developers. This document provides an overview of vapor intrusion and how it can affect redevelopment. It also summarizes techniques for quickly and cost effectively assessing the potential for vapor intrusion, which can be implemented in consultation with qualified scientists and engineers.
