  • LC-MS/MS Analysis Of PFAS Extractables In Polyethersulfone (PES) Syringe Filters Using EPA 537.1
    5/18/2022

    A key consideration for any PFAS method is to avoid contamination that can impact the accuracy of data, including those coming from sample preparation techniques such as filtration.

  • Optimizing PFAS Removal In The Presence Of Other Contaminants
    1/19/2022

    Here are some considerations that can help water treatment plant (WTP) supervisors, operators, and their consulting engineers achieve their PFAS removal goals more efficiently and cost effectively despite the added challenges.

  • PFAS Testing Program
    12/14/2021

    Every water source has different underlying chemistry. Furthermore, there are over 4,500 compounds currently classified as PFAS compounds, and each contaminated water source can have a different makeup of PFAS in it. By testing at multiple stages and scales, we are able to select and optimize treatment to fit the chemistry of the water rather than employing a “one size fits all” mentality. The treatment is customized to the water to reduce energy, breakthrough, waste products, and operation and maintenance costs.

  • AOS Advanced Oxidation System
    12/14/2021

    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.

  • Aqueous Electrostatic Concentrator
    12/14/2021

    The Aqueous Electrostatic Concentrator's (AEC) modular design provides a small footprint, and low energy consumption, that can be skidded, trailer mounted or custom configured to fit into existing spaces. Unlike traditional removal technologies, this non-carbon based treatment option is highly tolerant of TSS and TDS

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.
