Forever Chemicals Accumulate on Wastewater Filters Used for Drinking Water

Researchers at Texas A&M University have discovered that per- and polyfluoroalkyl substances (PFAS), often called "forever chemicals," build up significantly on filters used in advanced wastewater treatment processes. These advanced systems are increasingly being adopted by cities worldwide to augment their drinking water supplies by recycling wastewater. The study, conducted by the Department of Civil and Environmental Engineering, highlights a crucial environmental safety concern associated with this growing trend. The accumulation of PFAS on these purification filters indicates a potential challenge in ensuring the safety of recycled water intended for human consumption. This finding underscores the need for further investigation into the long-term implications of using such filters in drinking water production. The research points to a critical environmental safety consideration as more municipalities turn to these technologies. The presence of these persistent chemicals on filters used to create potable water from wastewater requires careful management and assessment.
