Project Duration: December 2023 – December 2025
Current Team Status
The team has finalized their deliverable and the Vapor Intrusion Toolkit has been released. The toolkit includes their main resource document, a series of fact sheets, checklists, tech sheets, and vapor intrusion YouTube playlists. Go check it out!
What is Vapor Intrusion?
Vapor Intrusion is the process by which volatile vapors partition from contaminated groundwater or other subsurface sources and migrate upward through vadose zone soils and into overlying buildings. Read more in the Team Info Sheet.
Why are we doing this?
ITRC has created several guidance documents and training focused on evaluating and mitigating the vapor intrusion pathway since 2007. There have been several advancements in technical and decision-making approaches. This Team will review and update information contained in the previous ITRC documents, and create a new comprehensive web-based guidance document and training products.
