TCE Short-Term Vapor Intrusion Risks

Tuesday, April 9 • 1:00 pm - 3:00 pm ET
Members $ 169.00; Non-Members $ 229.00

More often regulators are requesting rapid action at buildings with elevated trichloroethylene (TCE) indoor levels due to vapor intrusion (VI), including mitigating within weeks, or in some cases, relocating building occupants.  There is scientific controversy about TCE ad-hoc rapid action levels and the assumed toxic effect of fetal cardiac malformations. This has triggered new research, systematic reviews/publications, and working groups. Strategies have emerged to better plan VI investigations, develop rapid mitigation alternatives, proactively communicate risk, and assess effectiveness of response actions.
This webinar will present a brief history on TCE short-term toxicity, an overview of the controversy, a review of rapid action levels, investigation/management strategies, and multiple stakeholder perspectives. This critical information will help participants better assess the need, urgency, and type of TCE rapid responses due to VI.

Moderator: 

Christopher Lutes, Principal Technologist, Jacobs

Chris Lutes of Jacobs is a nationally recognized expert in vapor intrusion (VI).  He has worked on commercial and military VI projects in more than 18 states and several countries. He served on a ANSI/AARST committee that wrote a mitigation standard for 1-4 family residences.  He coauthored four EPA engineering issues on VI:  mitigation, air cleaners, passive samplers and excavation applications.   He has conducted EPA research studies on uses of radon as a tracer in VI, temporal variability, soil vapor extraction and passive sampling. 
Chris received his M.S., in Environmental Science and Engineering at UNC and
B.S., Chemistry,  from UVa.
