In this episode Talking Under Water co-hosts discuss EPA’s draft guidance on PFAS in biosolids, lessons utilities can take from the PFAS regulatory landscape to prepare for future contaminants, and recent developments affecting stormwater and water infrastructure projects.

Bob Crossen explains EPA’s newly released guidance for reducing risks associated with PFOA and PFOS in biosolids, highlighting the agency’s emphasis on source control, monitoring, pollution prevention, and public engagement through the ongoing comment period. He examines how states such as Michigan have successfully reduced PFAS loadings through pretreatment programs and discusses the challenges utilities face when land application options become restricted.

Mandy Crispin shares key insights from an ACE panel discussion focused on what PFAS can teach utilities about preparing for future contaminant regulations. She outlines emerging contaminants that could draw future regulatory attention and emphasizes the importance of documenting contaminant-specific costs, testing efforts, treatment decisions, staff time, and public outreach activities. These records could prove valuable for compliance, funding opportunities, and potential cost recovery efforts in the future.

The episode concludes with stormwater news covering Michigan dam safety legislation, EPA-approved groundwater remediation plans in Wyandotte, and Florida funding to strengthen wastewater infrastructure following Hurricane Milton.
