After The Fire: What The 2026 Wildfires And El Niño Could Mean For U.S. Lakes And Reservoirs In 2027 In July, smoke from Canadian wildfires spread across the upper Midwest and Northeast. Now a strengthening El Niño is set to influence the coming winter. Both events matter to lake and reservoir managers because their effects on water quality will continue to emerge long after the skies clear or the El Niño passes.

Pretreatment Systems Enable Complete And More Economical PFAS Solutions For operators looking to optimize their PFAS removal systems, controlling the presence of dissolved organic carbon (DOC) offers an approach to minimizing operational costs due to granular activated carbon (GAC) reactivation and ion exchange media change-out.
-
What Utilities Don't Know About GAC Reuse For PFAS For utilities building PFAS treatment systems, thermal reactivation of spent granular activated carbon (GAC) may sound like the obvious answer. However, service provider availability and location, specific media acceptance criteria including quantity thresholds, restrictions on GAC type and condition, and regulatory uncertainty can all determine whether reuse is a viable option.

The Cost Of Waiting: Utilities Face A Narrowing PFAS Compliance Window For years, the water industry's PFAS conversation centered on monitoring, testing, and regulatory anticipation. Today, that phase is largely over.
-
PFAS Funding Is Flowing — But Does The Water Sector Have Enough People To Deliver It? For several years, the PFAS conversation has centered on treatment options, testing, and funding. Those factors still matter, but they are no longer the primary constraint. Most utilities already understand the treatment routes available to them; the real challenge now is moving from technical possibility to operational performance, and that depends entirely on people.

The U.S. EPA is testing a new procedural strategy to remove four PFAS drinking‑water limits from ongoing litigation, asking the D.C. Circuit Court of Appeals to invalidate those limits on the grounds that the EPA itself committed a procedural misstep when issuing the 2024 PFAS rule.
-
Despite renewed public concern over fluoride and cognition, the National Toxicology Program’s findings focus on high‑fluoride groundwater conditions — not the controlled levels used in U.S. drinking water systems. Understanding that distinction is critical for utilities navigating policy questions and community expectations.
