Use the Maine Tracking Network data portal to find private well water quality data (for arsenic, fluoride, manganese, nitrate, nitrite, and uranium) for towns, Healthy Maine Partnership service areas, counties, public health districts, and the state. The data portal is also home to Behavioral Risk Factor Surveillance System data about homes with wells and well water testing behavior.

In the interactive data portal, you can create your own customized maps, tables, and charts to better understand private well water quality and testing in your area.
