New Community Resource For Vapor Intrusion Evaluation

Posted on by Mick

The Wisconsin Department of Natural Resources (DNR) is now offering an online resource tool for local governments, neighborhood associations and property owners to evaluate sources and minimize the risks of vapor intrusion from historical dry-cleaning operations in their communities.

For much of the 1900s, dry cleaning was a common business especially in Iarge cities where the service could be found on almost every commercial block. The disposal or spilling of cleaning solvents used by historical dry cleaners, long before current waste management laws were in effect, may have resulted in chemical vapors in the ground that can migrate into present-day buildings.

Now Available: Publication RR-649, Guidance for Documenting the Investigation of Human-made Preferential Pathways Including Utility Corridors

Posted on by Mick

Following a public comment period and consideration of the comments received, the publication RR-649, Guidance for Documenting the Investigation of Human-made Preferential Pathways Including Utility Corridors, is now posted and available online.

RR-649, formerly titled Guidance for Investigating Utilities, focused on investigating the migration of contamination in media along the exterior of utility corridors within the surrounding utility bedding. Current research indicates that contamination and vapors may migrate within utilities as well as other preferential pathways and the updated version of RR-649 reflects this new understanding. For additional information, please see the July 2020 Issues & Trends webinar, Vapor Intrusion: New Preferential Pathways, in the Remediation and Redevelopment Program’s training library.
