AK HB235

Requires the Alaska Department of Environmental Conservation to test all public water systems annually for PFAS contamination and provide alternative drinking water at no cost when contamination exceeds limits (4-10 parts per trillion depending on substance)

Establishes liability framework where persons who release PFAS in violation of laws or manufacturer instructions are responsible for drinking water and testing costs; manufacturers bear liability when users followed all proper instructions

Requires facilities performing thermal remediation of PFAS contamination to obtain Clean Air Act permits and prohibits permits if remediation would release more than minimal airborne carbon-fluorine compounds

Applies retroactively to PFAS releases occurring before, on, or after the effective date

Takes effect January 1, 2027, with the retroactivity provision taking effect immediately upon passage
