CalEPA Vapor Intrusion Workshops 2025-2026

CalEPA is spearheading a series of vapor intrusion workshops to:

1) share current knowledge, tools, and strategies that CalEPA agencies are using to evaluate sites where VI may pose a potential health risk; and

2) update the public and interested parties on the agency’s efforts to collect data and case studies to potentially develop California specific attenuation factors. 

Monthly technical workshops are planned to cover such topics as: conceptual site model best practices; VI screening to site closure; collective decision making with VI partners; VI in the community; VI data in Geotracker.  The kick-off meeting will take place on July 24th at 9am.
