To protect communities from PFAS-related severe illnesses, the U.S. Environmental Protection Agency (EPA) since June 2022 has published interim health advisories for Perfluorooctanoic acid (PFOA) and Perfluorooctane sulfonate (PFOS). In March 2023, the EPA announced the proposed National Primary Drinking Water Regulation (NPDWR) for PFOA, PFOS and four additional PFAS chemicals. The proposed regulation establishes legally enforceable levels — or Maximum Contaminant Levels (MCLs) — for these six PFAS. If finalized by the end of 2023, public water systems that exceed proposed standards would be required to reduce PFAS levels in drinking water.
Below, we discuss some standard technologies used in drinking water treatment facilities for PFAS removal from water and why you need an experienced team of water engineers to determine the most effective water treatment technology for your community.
There is extensive ongoing research at the bench-, pilot- and full-scale levels to determine which methods or technologies work best to remove PFAS from drinking water. The table below lists a few of the most studied technologies shown to effectively remove PFAS from drinking water.
At Fehr Graham, we are committed to helping communities design cost-effective, state-of-the-art water systems to secure safe drinking water. From planning and designing water treatment systems for PFAS removal, obtaining funding for system upgrades and overseeing construction, our multidisciplinary team helps you comply with proposed standards for PFAS chemicals in drinking water.
