What is PFAS and how did it get in the water?

PFAS stands for per- and polyfluoroalkyl substances. The 3M Company made PFAS at its Cottage Grove facility beginning in the 1940s. They were commonly used in household and industrial products such as stain repellents, lubricants, fire retardants and suppressants, and more. PFAS wastes were disposed of at various locations in Washington County. The source of PFAS in Woodbury's groundwater has been identified as these disposal sites.
