Alyssa Sellwood, a Hydrogeologist with the Remediation and Redevelopment Program and the leader of the dry cleaning and vapor intrusion teams, will present the next Issues & Trends training event on Wednesday, August 9, at noon. No pre-registration is required.

Sellwood’s presentation will be an overview of forthcoming additions and modifications to the RR Program’s existing guidance on vapor intrusion – RR 800 – Addressing Vapor Intrusion at Remediation and Redevelopment Sites in Wisconsin. We originally published the guidance in 2010, but revisions are necessary as knowledge and understanding of vapor intrusion has grown. The guidance is being readied for public comment and includes such updates as commissioning and inspecting vapor mitigation systems, mitigating vapor risk in new construction, and evaluating and addressing potential vapor risk in large commercial and industrial buildings.
