In this episode, Talking Under Water co‑hosts discuss the newest PFAS regulatory developments, major legal challenges, and the mounting strain on water and stormwater infrastructure across the U.S. The conversation begins with the EPA’s decision to add PFHXSNA to the Toxics Release Inventory, expanding federal PFAS tracking and community access to chemical data. The hosts then outline the unfolding court battle over EPA’s PFAS drinking water rule, detailing the agency’s motion to sever and pause litigation on the hazard index and the strong opposition filed by AWWA and AMWA, who argue that utilities need unified judicial review to plan for compliance.
 
The episode also explores the Supreme Court’s recent ruling striking down President Trump’s tariff plan and how the administration is seeking new legal pathways to maintain tariffs. From there, the hosts examine the politically charged response to the Potomac Interceptor sewer collapse, highlighting the operational, financial, and communication challenges surrounding the incident.
 
Closing out, the show turns to stormwater struggles on both coasts — catch basin failures and compliance gaps in Connecticut, and severe flooding, lawsuits, and multibillion‑dollar funding shortfalls in San Diego — underscoring nationwide infrastructure vulnerabilities. The episode concludes with key industry updates and program announcements.
