The Vapor Intrusion Mitigation training is a series of eight (8) modules, presented over two sessions.

The Vapor Intrusion Mitigation training series provides an overview of vapor intrusion mitigation and presenting information from the ITRC fact sheets, technology information sheets, and checklists (VIM-1, 2021):

Session 1:

• Introduction & Overview of Vapor Intrusion Mitigation Training Team
• Conceptual Site Models for Vapor Intrusion Mitigation
• Public Outreach During Vapor Intrusion Mitigation
• Rapid Response & Ventilation for Vapor Intrusion Mitigation
• Remediation & Institutional Controls

Session 2:

• Active Mitigation Approaches
• Passive Mitigation Approaches
• System Verification, OM&M, and Exit Strategies

When certain contaminants or hazardous substances are released into the soil or groundwater, they may volatilize into soil gas. Vapor intrusion (VI) occurs when these vapors migrate up into overlying buildings and contaminate indoor air. ITRC has previously released guidance documents focused on VI, including the "Vapor Intrusion Pathway: A Practical Guidance" (VI-1, 2007) and "Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management" (PVI, 2014). However, ITRC has received multiple requests for additional details and training on mitigation strategies for addressing this exposure pathway.

The ITRC Vapor Intrusion Mitigation Team (VIMT) created ten fact sheets, 16 technology information sheets, and 4 checklists with the goal of assisting regulators during review of vapor intrusion mitigation systems, and helping contractors understand the essential elements of planning, design, implementation, and operation, maintenance and monitoring (OM&M) of mitigation systems.

• How to locate and utilize the VIM-1 fact sheets, technology information sheets, and checklists
• The importance of a VI mitigation conceptual site model
• How public outreach for VI mitigation differs from other environmental matters
• When to implement rapid response for vapor intrusion and applicable methodologies
• The differences between remediation, mitigation, and institutional controls
• Available technologies for active and passive mitigation, and design considerations for various approaches
• How/when/why different mitigation technologies are appropriate
• How to verify mitigation system success, address underperformance, and develop a plan for discontinuing a mitigation system
