On June 7, the Wisconsin Department of Health Services (DHS) provided the Wisconsin Department of Natural Resources (DNR) with an updated letter on the utilization of the hazard index (HI) approach to assess the cumulative risk of PFAS (per- and polyfluoroalkyl substances).

This updated letter clarifies recommendations provided to the DNR in November 2020, making clear that the hazard index should be reported to one decimal place (examples are provided in the memo). No other changes to the DHS recommended approach were made.

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.
