Title:DRAFT GUIDANCE FOR EVALUATING THE VAPOR INTRUSION TO INDOOR AIR PATHWAY FROM GROUNDWATER AND SOILS: Subsurface Vapor Intrusion Guidance
Document Date:11/01/2002
Description:This draft guidance specifically addresses the evaluation of a single exposure pathway – the vapor intrusion pathway. The intent of this draft guidance is to provide a tool to help the user conduct a screening evaluation as to whether or not the vapor intrusion exposure pathway is complete and, if so, whether it poses an unacceptable risk to human health. A complete pathway means that humans are exposed to vapors originating from site contamination. The approach suggested in this draft guidance begins with simple and generally reasonable conservative screening approaches and gradually progresses toward a more complex assessment involving increasingly greater use of site-specific data. This guidance is not intended to provide recommendations on how to delineate the extent of risk or how to eliminate the risk, only to determine if there is a potential for an unacceptable risk.
