How does the Colorado Department of Public Health and Environment (CDPHE) regulate PFAS?

The CDPHE regulates PFAS based on the U.S. Environmental Protection Agency’s (EPA) advisories. The EPA established a health advisory level for two of the chemicals in the Per- and polyfluoroalkyl substances (PFAS) family. A health advisory level is to safeguard people, especially sensitive groups, with a margin of protection. This advisory is for PFOA and PFOS combined at 70 parts per trillion.
