USGS Study Reveals Widespread PFAS Contamination in Groundwater

Up to 95 million Americans may rely on drinking water with detectable levels of 'forever chemicals,' posing potential health risks.

The US Geological Survey estimates that over 20% of the US population may use groundwater contaminated with PFAS for drinking.
PFAS, or 'forever chemicals,' are synthetic substances found in everyday products and linked to health risks like cancer and high cholesterol.
The study provides the first national estimates of PFAS presence in untreated groundwater for both public and private wells.
States with the highest potential exposure include Florida, California, Michigan, North Carolina, Pennsylvania, New York, and Ohio.
USGS has developed an interactive map showing PFAS contamination probabilities to aid public awareness and guide future water safety measures.
