PFAS remains one of water’s toughest and most urgent challenges — a class of thousands of persistent compounds still only partly understood but deeply embedded in modern life and the environment. In this episode, Peter Grevatt, CEO of The Water Research Foundation, discusses the state of PFAS research, including how science is closing critical knowledge gaps and revealing where the next breakthroughs may come.Grevatt explains how new “total PFAS” and precursor testing methods are helping researchers glimpse what lies beneath the surface — the larger iceberg of unmeasured chemicals. National studies led by WRF are also reshaping assumptions about where PFAS comes from, showing that domestic wastewater may contribute a greater overall mass than industrial sources. AI is beginning to aid detection, with early research into “fingerprinting” PFAS signatures from fire training sites, landfills, and other sources to help utilities identify where contamination originates.When it comes to solutions, Grevatt outlines a field in motion rather than finished answers. Granular activated carbon, ion exchange, and reverse osmosis remain reliable workhorses, but their limits—especially with short-chain PFAS—are driving studies on tailored treatment media and lower-cost destruction technologies.Grevatt also highlights growing research on PFAS in biosolids and the global search for safe management options, from land application to disposal.

The hard-fought plan to restore salmon runs in the Pacific Northwest has been abruptly derailed, threatening one of the most significant tribal and environmental agreements in decades. In this episode of In The Newsroom, Tony Schick of Oregon Public Broadcasting breaks down how the Trump administration scrapped a landmark deal that would have paved the way for breaching four Snake River dams to save salmon populations. The agreement, developed under the Biden administration with tribes, states, and environmental groups, paused decades of litigation in exchange for bold steps: river restoration, hatchery investment, and renewable energy projects led by tribal nations. The goal was to replace the dams’ hydropower with solar, wind, and storage solutions, giving salmon a shot at recovery while meeting rising energy demands. Schick explains how the deal began to unravel even before the administration change, with funding delays and personnel exits signaling trouble. Tribes now face yet another broken promise—despite holding treaty rights to fish in waters increasingly devoid of fish. With legal battles likely to return, this story underscores how fragile progress can be when politics collide with ecological urgency.waterloop is a nonprofit news outlet exploring solutions for water sustainability.
