“Recent Changes in California’s Vapor Intrusion Guidance”

Posted on Author sacpema_adminPosted in Past Meetings

Environmental practitioners face numerous challenges when evaluating exposure to subsurface
vapors that migrate into buildings. To assist in these evaluations, DTSC guidance has been updated to reflect recent developments in the field of vapor intrusion.  This presentation will review the difficulties associated with obtaining representative data for exposure assessments. Additionally, new technologies for indoor air sampling will be discussed, along with issues associated with confirmation sampling upon completion of site remediation.

Dan Gallagher is a Senior Engineering Geologist with the Department of Toxic Substances Control, where he provides geological support on contaminated sites and monitoring activities at hazardous waste landfills. He joined DTSC in 1999 after spending five years with Chevron Products Company as an environmental project manager and four years with Chevron Research and Technology Company as a hydrogeologist.  He has an MS in geology from the University of Utah and a BS in geology from
the University of Southern California, and he is a California Certified Hydrogeologist.
