High levels of forever chemicals found on wastewater filters

As cities across the nation and the globe increasingly turn to advanced water purification systems to expand their drinking water supplies, researchers at Texas A&M University have identified a critical environmental safety consideration. A new study from the Department of Civil and Environmental Engineering shows that per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals," accumulate significantly on the purification filters used in advanced treatment to recycle wastewater into drinking water.
