Issues & Trends Webinar on Nov. 16, 2022: Passive Air Sampling for Vapor Intrusion

The Remediation and Redevelopment (RR) Program shares that the next webinar in the Issues & Trends series will take place on Nov. 16, 2022, from noon-1 p.m.

The scheduled presentation is Passive Air Sampling for Vapor Intrusion.

The webinar will spotlight changes in recommendations for vapor intrusion sampling (e.g., longer duration passive sampling in lieu of evacuated canister sampling for vapor intrusion investigations).

Colder temperatures and the indoor heating season are the preferred conditions for conducting vapor intrusion sampling. In anticipation of increased sampling during the winter months, DNR staff will provide the latest recommendations for sampling methods for soil gas, sanitary sewer and sewer cleanouts, indoor air and sub-slab vapor.

Additional topics addressed during the webinar will include a review of the health risk concerns and randomly timed 8-hr or 24-hr samples, different passive samplers, considerations when selecting appropriate samples and how to evaluate the data.

Environmental consultants working on sites with volatile organic compounds (VOCs), particularly chlorinated solvent sites, are encouraged to attend.

A Zoom web conferencing registration link may be found on the RR Program’s Conferences and Training webpage.

Recordings of previous Issues & Trends webinars may be found in the RR Program’s Training Library.
