State AGs and PFAS: A Growing Coalition
State attorneys general have become major drivers of PFAS accountability, both through litigation against manufacturers and through legislative advocacy for stronger federal standards. Multi-state coalitions amplify individual state power and send coordinated signals to industry and federal agencies about PFAS regulatory priorities.
Multi-State Litigation Coordination
State AG offices in New York, Michigan, Minnesota, California, and over 20 other states have coordinated PFAS litigation strategies through the National Association of Attorneys General (NAAG) working group. This coordination maximizes negotiating leverage, shares investigation costs, and ensures consistent application of state consumer protection and environmental laws against PFAS manufacturers.
Legislative Advocacy Coalitions
State AG coalitions have submitted formal comments to EPA supporting stringent PFAS MCLs, TSCA reporting rules, and CERCLA hazardous substance designation. These coordinated regulatory advocacy efforts demonstrate bipartisan support for strong federal PFAS action across Republican and Democratic states alike—reflecting the geographic universality of PFAS contamination.
Settlement Structure Influence
Multi-state AG settlements have shaped PFAS manufacturer liability resolution in important ways. State coalitions negotiated provisions in 3M and DuPont settlements requiring public disclosure of PFAS-related research, restrictions on new PFAS introductions, and funding allocations to specific state cleanup priorities—provisions that individual state negotiations could not have achieved.
