Widespread Contamination: Alarming Levels of PFAS Found in US Tap Water
Approximately 45% of US tap water sources, including public water systems and private water wells, are contaminated with PFAS (per- and polyfluoroalkyl substances), according to research by US Geological Survey scientists. The study reveals that urban areas, particularly in the Great Plains and Great Lakes regions, the East Coast, and central and southern California, are most at risk. PFAS, which have been linked to cancer and other health problems, are commonly found in industrial and consumer products. The study highlights the need for more data on PFAS contamination in private water wells, as well as the importance of implementing stricter regulations to limit PFAS levels in drinking water.
