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. -

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. -

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

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. -

DRINKING WATER PRODUCTS
Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.
Highly effective against bacteria and viruses, the Advanced Oxidation System (AOS) is also well-suited for the decontamination of hard-to-treat organic contaminants such as pharmaceuticals and other micropollutants The AOS can be configured to deliver optimized performance for most water or wastewater treatment applications.
The DE NORA TETRA® ABF bioactive filter combines ozone generation with biologically active filtration for use in municipal water applications. The process targets micropollutant reduction and reduces disinfection byproducts in drinking water and potable reuse applications.
