  • Monitoring Know-How For PFAS Regulations
    10/31/2024
    A Q&A to explain and resolve issues confronting water suppliers as they endeavor to comply with the monitoring requirements of federal PFAS regulations.
  • Innovative PFAS Treatment Proves Less Is More
    10/30/2024

    A new PFAS treatment system from the University of British Columbia (UBC) features a patented UV catalyst that requires only minimal light, making it much more energy-efficient. Learn more from two of the principals involved in its development.

  • NanoSORB™ Membrane Bioreactor (MBR)
    10/4/2024

    ECT2’s research and development team has developed a novel technology called NanoSORBTM that leverages the activated sludge process tankage for PFAS removal.

  • AquaPRS PFAS Removal System
    9/23/2024

    The AquaPRS™ PFAS Removal System utilizes a unique sorbent suspension to adsorb per- and polyfluoroalkyl substances (PFAS) and a robust separator to extract clean water from the suspension. The turbulent adsorbent slurry prevents biofouling and controls solids and mineral buildup.

  • AFFF Cleanout And Transition Service
    8/5/2024

    As an essential tool for firefighting agencies and emergency services worldwide, Aqueous Film Forming Foams (AFFF) have been favored to provide a rapid and effective solution to suppress fires. Unfortunately, AFFF contains per- and polyfluoroalkyl substances (PFAS) which have both adverse environmental impact and potential health risks.

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.
