Per- and polyfluoroalkyl substances (PFAS) are a group of thousands of different synthetic chemicals that are used widely in products and industrial processes. A few of the most-studied PFAS are known to be hazardous to human health. Since PFAS contamination was detected in drinking water in the eastern Twin Cities in the early 2000s, the chemicals have been found in water, sediment, soil, and fish all across Minnesota.
