An Act relating to perfluoroalkyl and polyfluoroalkyl substances; relating to thermal remediation of perfluoroalkyl and polyfluoroalkyl substance contamination; and providing for an effective date.

HB 235 requires Alaska's Department of Environmental Conservation to test all public drinking water systems annually for perfluoroalkyl and polyfluoroalkyl substances (PFAS), harmful chemicals found in products like nonstick coatings and firefighting foam. If PFAS levels exceed specific safety limits (e.g., 4 parts per trillion for perfluorooctanoic acid), the state must provide free, safe drinking water to affected residents. The bill also establishes liability: entities that release PFAS without following safety rules must cover cleanup costs, while manufacturers may be liable if users complied with all regulations. This law directly affects public water systems, residents in contaminated areas, and companies handling PFAS-containing products.
