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:<ul><li>Vapor intrusion fundamentals and conceptual site models</li><li>Site screening and investigation strategies</li><li>Sampling and analysis</li><li>Data evaluation and risk assessment</li><li>Modeling</li><li>Vapor intrusion mitigation</li><li>Community engagement</li></ul><br /> 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: <em>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)</em>. 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.<br /> <br /> 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.

Participants will learn practical design considerations, including hydrogeology, climate, and long-term maintenance, along with realistic performance expectations. Lessons learned in monitoring, system performance, and sustainability co-benefits, such as habitat creation and climate resilience, are emphasized to help teams design defensible, effective phytoremediation projects.<br /> <br /> Concepts are reinforced through real-world case studies demonstrating phytoremediation in practice. Attendees will explore applied case studies illustrating diverse uses of phytotechnology, including hybrid treatment systems for complex groundwater contamination, hydraulic plume control using deep-rooted trees, remediation of petroleum impacts in coastal environments, and large-scale natural treatment systems for nutrient management. These examples highlight both the opportunities and limitations of phytoremediation and provide actionable insights for determining when and how it can be effectively integrated into remediation strategies.
