Tracking PFAS levels in Maine's public water systems

Each public water system's approach to its contamination has varied with its PFAS levels and hydrogeology, but most are pursuing carbon filtration systems.

The public water systems listed had tested at or above the state's 20 ppt threshold before April 9, 2024; Maine's most recent comprehensive results. The data shown was pulled from more recent results for individual systems and a Monitor survey. It may not include the most up-to-date information.
