An Act To Expand Testing For Perfluoroalkyl And Polyfluoroalkyl Substances To Private Drinking Water Wells
LD 493 requires landlords of residential buildings with private drinking water wells to test for perfluoroalkyl and polyfluoroalkyl substances (PFAS) by January 1, 2026, and share results with tenants. It also mandates home sellers to disclose any past PFAS test results to potential buyers. The bill adds PFAS to the list of contaminants the Maine Department of Health and Human Services must include in its uniform testing recommendations for private wells, alongside existing contaminants like arsenic and bacteria. This applies to all residential properties using private wells across Maine.
