PFAS are currently not regulated in drinking water at the federal level, however, the Environmental Protection Agency (EPA) has begun the process of regulating PFOS and PROA in drinking water and it is very likely that maximum containment levels (MCLs) will be established for a least these 2 PFAS contaminants in the future. In lieu of a federal drinking water regulation, several states have or are in the process of developing their own MLCs or health advisory levels.
