Per- and polyfluoroalkul substances (PFAS) have garnered significant scientific, regulatory, and public attention due to their recalcitrant, ecological persistence, and widespread occurrence—thus the moniker "forever chemicals." PFAS has been detected in groundwater and in finished drinking water throughout the United States. Six PFAS were included in the Third Unregulated Contaminant Monitoring Rule, which required sampling of finished drinking water from a subset of U.S. public water systems between 2013 and 2015. Of the samples collected from water systems with a groundwater source, 1.2% contained perfluorooctanoic acid (PFOA) at or above the minimum reporting level of 20 nanograms per liter (ng/L).
