Gain extensive knowledge on VI with our pre-conference course on Tuesday, December 4. 

Advances in Assessing the Vapor Intrusion Pathway
Instructors:  Robert Ettinger, Senior Principal, Geosyntec and Loren Lund, Ph.D. VI/Risk Assessment Leader, Jacobs 
December 4, 1:00 pm - 5:00 pm 

This course will provide an understanding of state-of-the-practice advances for addressing the vapor intrusion (VI) pathway.  Methods for addressing VI continue to evolve in response to emerging policies on TCE short-term toxicity/rapid response, uncertainties with technologies used over the last 10-15 years, an evolving understanding of atypical preferential vapor transport, and the need to address and mitigate VI more efficiently and cost effectively.  Next-generation VI investigation and mitigation technologies that will be discussed in this half-day course include:

  • A VI quantitative decision framework for systematically assessing multiple lines of evidence
  • An understanding/managing temporal and spatial variability
    • Indicators, tracers, and surrogates
    • Building pressure cycling with near real-time sampling
    • High volume subslab soil gas sampling
    • Continuous monitoring
    • Passive samplers and canister low-flow controllers
  • Assessing/managing TCE short-term exposure/toxicity
  • Understanding/mitigating atypical preferential vapor transport
  • Advanced approaches for vapor intrusion mitigation
    • Data collection for mitigation system design
    • Evaluation of mitigation system effectiveness
    • Soil Vapor Extraction (SVE) to prevent VI
Case studies and/or hands-on exhibits or demonstrations will complement the lecture portion of this course. A fundamental understanding of the VI pathway is a beneficial, but not required prerequisite for attendees.
