Are PFAS regulated?

National drinking water quality standards are set by the EPA and administered in our state by the Colorado Department of Public Health and Environment (CDPHE). Under the Safe Drinking Water Act, the EPA issues national health-based standards for drinking water to protect against both naturally occurring and man-made substances that may be found in drinking water.
 
To date, PFAS compounds (a group of thousands of per and polyfluoroalkyl substances) are not regulated. Recently, the EPA released new recommendations, known as health advisories, on two compounds, GenX and PFBS, and lower health advisories for PFOA and PFOS and is evaluating additional actions to address other PFAS. 

Castle Rock Water is preparing for these future regulations and is currently using granular activated carbon, one of the best treatment technologies available for removing PFAS from water, to remove PFAS down to laboratory reporting levels.
