• 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 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.

• D.C. Circuit Upholds EPA's Hazardous Substance Designation For PFOA, PFOS

  The U.S. Court of Appeals for the D.C. Circuit recently rejected industry challenges to the EPA's designation of PFOA and PFOS as hazardous substances under CERCLA, leaving the agency's April 2024 rule fully intact. While the case centered on the EPA's authority to make the designation, its practical significance for water utilities is simpler: the liability concerns that have accompanied the rule since its adoption remain unresolved.

• How Donner Summit PUD Cut Backwash Water Use By 45% With Ultrasonic Algae Control

  Recurring algal blooms severely compromise water treatment efficiency, clogging filters and wasting finished water through frequent backwashing. Targeted ultrasonic suppression controls raw water algae growth at the source, significantly improving influent turbidity and lowering operational costs.

• SRP-Funded Technology Provides Affordable PFAS Testing For Homeowners

  Widespread chemical contamination leaves many small water systems without viable testing options.Discover how an innovative, plant-based extraction method delivers affordable, highly accurate screening to identify complex contaminants and protect public health.

• The Enzyme Bottleneck: Why Conventional Lake Management Is Failing — And What The Science Says About Genuine Bio-Dredging For decades, the dominant framework for assessing and managing lake health has been built around surface water measurements: chlorophyll-a, total phosphorus, water clarity, and the composite Trophic State Index derived from them. These metrics are familiar, standardized, and widely accepted. They are also, according to a growing body of peer-reviewed literature, measuring the wrong part of the lake.
• Ozone Off-Gas: What It Reveals About System Efficiency, Safety, and Design

  Learn how ozone off-gas impacts system efficiency, safety, and performance, and why monitoring and management are critical for optimized water treatment operations.

• UK Reservoirs, Water Shortages, And Legionella Risks Is there a clear link between a less plentiful water supply and an increase in Legionella in our domestic water systems?
• The Devastating Legacy Of Algaecides: Why The Quick Fix Is Failing Our Lakes As warmer months approach, water management professionals must confront the compounding consequences of biocidal algae treatments.
• What Is The Future Of Source Water Protection? Water utility managers and municipal leaders have long struggled amid the convergence of several threats to public water supplies. During a recent Water Online Live event, I sat with a panel of industry experts to examine the transition from reactive crisis management to a proactive, adaptive resilience framework.
