State Drinking Water Standards for PFAS
Eleven states (ME, MA, MI, NH, NJ, NY, PA, RI, VT, WA, and WI) have enforceable standards such as Maximum Contaminant Levels (MCLs) for certain PFAS in drinking water. Maine has an interim standard that is in effect and enforceable while they go through rule-making to establish final MCLs for PFAS.
Sixteen states (AK, CA, CO, CT, HI, IL, IN, MD, MN, MS, MT, NM, NC, OH, OR, and WI) have adopted guidance, health advisory, or notification levels for certain PFAS chemicals.
