What Utilities Don't Know About GAC Reuse For PFASFor 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. -

CyanoFluor is a dual-channel handheld fluorometer designed for harmful algal bloom monitoring. By measuring chlorophyll-a and phycocyanin simultaneously, it differentiates cyanobacteria from other phytoplankton with precision. Portable, factory calibrated, and easy to use, CyanoFluor supports early detection, rapid assessment, and ongoing monitoring of blooms, protecting ecosystems, aquaculture, and drinking water supplies from the impacts of toxic algae.
Following 4”, 8” and 16” membranes can be used in multiple membrane systems to treat sea water or high salinity water > 10’000 ppm. The 4” membrane types can be used for small private or shipboard sea water desalination.
The Aqueous Electrostatic Concentrator's (AEC) modular design provides a small footprint and low energy consumption, and it can be skidded, trailer-mounted, or custom configured to fit into existing spaces.
