The U.S. Environmental Protection Agency indicates it will take years to regulate PFAS in drinking water, if it does at all.
The USEPA has proposed to regulate two forms of the thousands of chemicals in the per- and polyfluoroalkyl substances family. PFOA and PFOS were the most commonly used.
It will take a while before the agency decides whether to make a final determination to regulate the chemicals. It will then take up to two years to propose drinking water regulations and another year-and-a-half before they might be finalized. So, drinking water regulations are probably four years away or longer.
Meanwhile, the State of Michigan has already issued draft regulations for seven forms of PFAS. Michigan could issue final regulations on those chemicals in drinking water in April.
