  • New Method Turns Harmful Environmental Waste Into Useful Synthetic Reagent
    9/11/2026

    Fluorinated waste, like that found in firefighting aqueous film-forming foam, can act as a significant environmental pollutant. Recently, James Tour’s lab at Rice University developed a method to capture the fluoride from these waste streams and recycle it into a useful reagent, silver fluoride, that could be used in other manufacturing processes. This process was recently published in Nature Chemical Engineering.

  • What Utilities Don't Know About GAC Reuse For PFAS
    9/9/2026

    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
    9/4/2026
    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?
    9/4/2026

    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.

  • $7.9 Million NSF Investment Brings Vermont Researchers Together To Address 'Forever Chemical' Contamination
    9/2/2026

    The U.S. National Science Foundation has awarded $7.9 million to establish the PFAS Environmental Research Network (PERN), a four-year initiative bringing together Vermont researchers, educators, students, and state partners to better understand and address environmental chemical contamination.

  • EPA Releases Final UCMR 5 Drinking Water Data For PFAS And Lithium
    9/2/2026

    On August 27, the U.S. Environmental Protection Agency released the final set of national drinking water data collected under the fifth Unregulated Contaminant Monitoring Rule (UCMR 5) for 30 chemical contaminants: 29 PFAS plus lithium. The data collected under UCMR 5 improves understanding of the prevalence and amount of 29 PFAS and lithium in the nation’s drinking water systems.

  • Emerging Contaminants Follow Distinct Rules When Partitioning Between Sediment And Water, Study Finds
    8/26/2026

    For decades, environmental scientists have struggled to predict where emerging contaminants end up in rivers—whether they linger in sediments or remain mobile in the water. That uncertainty has made risk assessment difficult and management decisions unreliable.

  • D.C. Circuit Upholds EPA's Hazardous Substance Designation For PFOA, PFOS
    8/24/2026

    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.

  • AWWA Issues Statement Following Court Decision On PFAS And CERCLA
    8/18/2026

    The U.S. Court of Appeals for the D.C. Circuit today upheld EPA’s designation of PFOA and PFOS as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund. The American Water Works Association, which was not part of the litigation, issued the following statement.

  • How Insects Could Help Detect PFAS Contamination
    8/17/2026

    Researchers at Michigan State University have discovered that neurons in a locust’s brain can distinguish among multiple PFAS compounds, including PFOS, one of the world’s most common “forever chemicals,” at environmentally relevant concentrations.

  • Purofine™ PFA694EBF Buffered Resin For PFAS Treatment: Point-Of-Use (POU) And Point-Of-Entry (POE)
    8/10/2026

    Traditional ion exchange media can disrupt water chemistry and increase pipe corrosion risks during startup. Buffered treatment solutions stabilize pH and mineral ratios immediately, delivering consistent, safe performance across intermittent residential usage.

  • PFAS-Selective Single-Use Ion Exchange Resin: Environmental Discharge And Remediation
    8/10/2026

    Effective PFAS remediation demands precise prefiltration, controlled hydraulics, and optimized vessel configurations to prevent media fouling and premature contaminant breakthrough. Read the guide to implement best practices for maximum treatment efficiency.

  • PFAS-Selective Single-Use Ion Exchange Resin For Drinking Water Systems
    8/10/2026

    Achieving reliable drinking water decontamination using selective single-use ion exchange media requires careful hydraulic management, targeted prefiltration, and proper lead-lag vessel engineering to protect media integrity, prevent premature breakthrough, and maintain consistent effluent quality.

    4/29/2026

    Purolite Purofine PFA694E is the flagship PFAS-selective single-use ion exchange resin for drinking water and other PFAS remediation applications.  This proven product provides better short chain removal, smaller footprint, and significantly lower operational cost than competitive technologies. 

  • DEXSORB® Regeneration And Concentration Of PFAS Waste
    4/2/2026

    DEXSORB is a regenerable adsorbent media offering a cradle-to-grave solution in per- and polyfl uoroalkyl substances (PFAS) treatment. Effective desorption of PFAS from spent media is not only a critical step for enabling sustainable media reuse, but also for concentrating PFAS waste for its safe and cost-effective destruction.

PFAS MULTIMEDIA

Andrew Strassner, President of Sentinel Water Solutions, sits down with The Water Online Show to highlight the distinct operational advantages of custom-built, modular treatment systems.

ABOUT PFAS

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have sometimes been called “forever chemicals” for their persistent nature in the environment, difficulty to remove through treatment, and bioaccumulation in humans and animals. Two types of PFAS — perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) — have been identified as toxic by the U.S. EPA, while many more of the nearly 5,000 PFAS formulas are either suspected contaminants or have yet to be studied thoroughly. Originally developed for non-stick coatings, stain-repellant fabric treatments, and firefighting foams, PFAS are especially prevalent near former areas of high use — such as manufacturing facilities, airports, military bases, or the sites of large fires — yet widely problematic.

In February 2020, the EPA issued preliminary determinations to regulate PFOA and PFOS under the Safe Drinking Water Act (SDWA) and establish the first national PFAS monitoring and treatment requirements for drinking water utilities (see EPA’s PFAS Action Plan). Numerous U.S. states, however, have already developed rules and guidance for PFAS.

This solution center addresses the topics and questions most important to drinking water professionals as the PFAS issue evolves — How does PFAS get into drinking water? How do utilities monitor for PFAS? What treatment technologies remove PFAS? What are the regulatory limits for PFAS? — with answers provided through breaking news stories, editorial insight, and technical discussions.
