A new study published in the Proceedings of the National Academy of Sciences reveals that nearly 7% of Americans, or about 23 million people, may be exposed to hazardous levels of “forever chemicals” (PFAS) through treated municipal wastewater. These synthetic compounds, which are found in household products, industrial discharges, and firefighting foams, are not effectively removed by wastewater treatment facilities. As a result, PFAS reenter municipal drinking water networks.
Key findings include:
- PFAS persistence: These chemicals accumulate in the environment and the human body, and have been linked to cancers and other serious health issues.
- Increasing risk: The proportion of treated wastewater in drinking water resources is rising, potentially increasing exposure levels over time.
The study highlights the urgent need for improved wastewater treatment technologies to address this growing public health concern.
