The U.S. Environmental Protection Agency made $1 billion available in April 2024 specifically for PFAS-related drinking water investments, with additional tranches flowing through subsequent fiscal cycles. For utilities preparing capital projects against the PFAS compliance deadlines — 2029 in the final rule, with an extension path to 2031 for PFOA and PFOS — that funding…
Drinking water plants in the United States and Europe run two dominant filtration architectures: conventional treatment (coagulation, flocculation, sedimentation, filtration) and direct filtration (coagulation, in-line mixing, filtration without sedimentation). Both must meet the same finished-water turbidity targets, but they generate very different suspended solids profiles upstream of filtration. The sensor strategy that works in one…
Anion exchange (AIX) resins have emerged as one of the two leading PFAS treatment technologies in drinking water, alongside granular activated carbon. AIX achieves selective removal of long-chain PFAS at high empty-bed contact times and reasonable footprint. The engineering challenge is not adsorption capacity — that is well documented — but breakthrough detection, because most…
Much of the online chlorine analyzer fleet installed across North American and European water distribution networks dates to capital cycles in the 2000s and early 2010s, and it is reaching end-of-life concurrently with the EPA’s 2024 PFAS rulemakings and the Lead and Copper Rule Improvements. For utility procurement officers, the practical question is no longer…
Boil-water advisories are among the most consequential public-facing events a drinking water utility can issue. They reach every customer simultaneously, dominate local media coverage for days, and reset public trust in the utility for years. Behind every advisory sits a data record — and increasingly, that record is dominated by turbidity readings. Utility leadership teams…
Municipal drinking water utilities in 2026 are working through the largest compliance retrofit in a generation. EPA’s PFAS National Primary Drinking Water Regulation sets enforceable maximum contaminant levels of 4 parts per trillion (ppt) for PFOA and PFOS, 10 ppt for PFHxS, PFNA and HFPO-DA (GenX chemicals), and a hazard-index limit for mixtures. Initial monitoring…
