  "description": "State-by-state comparison of legally enforceable and advisory concentration limits for PFAS compounds in drinking water. Each record is one state\u2013chemical pair with the concentration limit (in parts per trillion), the regulation type (MCL, notification level, action level, health advisory, or guideline), the effective date, the statutory or regulatory citation, and whether the state limit is stricter than the federal EPA MCL. The federal MCLs are 4 ppt for PFOA and PFOS (affirmed May 2025); MCLs for PFHxS, PFNA, and HFPO-DA are under proposed rescission as of May 2026. State limits range from 0.00266 ppt (Nevada, PFOA) to 400,000 ppt (Michigan, PFHxA). Answers 'what is the legal PFAS limit in my state', 'is my state stricter than the federal standard', and 'which PFAS compounds does my state regulate'.",
