New Jersey Vapor Intrusion Guidance Finalized The New Jersey Department of Environmental Protection (DEP) has finalized its vapor intrusion guidance document to provide assistance in the evaluation of contaminated sites. The document has been modified after consideration of the latest state of the science and comments received on the draft document after it was placed on the DEP’s Web site for external review in June 2005. The document consists of a phased approach to investigate the vapor intrusion (VI) pathway that follows the basic provisions of the U.S. EPA draft vapor intrusion guidance, while incorporating New Jersey specific factors and policies, when appropriate. The guidance includes a discussion of the VI pathway, VI screening levels to be used in the evaluation of a site, sampling and analytical requirements, site-specific screening options, remedial options, monitoring and maintenance requirements, community outreach, and a methodology to evaluate background air concentrations.
