Audio for "ITRC's Vapor Intrusion Toolkit Resources – An Orientation," Jul 21, 2026

This orientation will provide a brief overview of vapor intrusion and introduce attendees to the 2026 ITRC Vapor Intrusion (VI) Toolkit and its many resources. The VI Toolkit includes the Vapor Intrusion Technical and Regulatory Guidance and a suite of fact sheets, technology information sheets, and checklists, all of which are individually available for download and use. Also provided is a series of YouTube Playlists featuring ITRC-produced videos and content from other organizations. Key topic areas addressed in the toolkit include:Vapor intrusion fundamentals and conceptual site modelsSite screening and investigation strategiesSampling and analysisData evaluation and risk assessmentModelingVapor intrusion mitigationCommunity engagement The Toolkit provides a comprehensive overview of vapor intrusion concepts, recommended practices, and decision-making approaches across a wide range of site conditions. The Toolkit replaces, combines, and updates three previous ITRC vapor intrusion guidance documents: Vapor Intrusion Pathway: A Practical Guidance (VI-1, 2007), Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management (PVI 1, 2014), and Technical Resources for Vapor Intrusion Mitigation (VIM-1, 2020). It reflects advances in science, policy, and field experience, and is designed to support regulators, practitioners, and stakeholders in conducting consistent and effective vapor intrusion assessments. The course will provide connections to the 2026 ITRC VI Toolkit to help the audience understand how to find and use these new resources, and upcoming live ITRC training opportunities that will provide more in-depth education concepts provided in the Toolkit.
