• Forever Chemicals Threaten Drinking Water: A new study by the USGS suggests groundwater for over 70 million Americans might be contaminated with “forever chemicals.”
• Forever Chemicals Defined: These are per- and polyfluoroalkyl substances (PFAS), man-made chemicals known for their persistence in the environment and potential health risks.
• Health Concerns: Exposure to PFAS has been linked to various health problems, including cancer, immune system issues, and developmental problems in children.
• Contamination Source: The study used private well data and found evidence of PFAS contamination in areas with industries known to use these chemicals.
• Limited Public Water System Data: The study focused on private wells, and data on PFAS levels in public water systems is currently limited.
• Need for Further Investigation: The USGS emphasizes the need for more comprehensive testing of both public and private water supplies to understand the full extent of PFAS contamination.
