What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Maine has 385 active non-transient non-community water systems, 21% of the state's 1,862 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,780 Maine systems (96%) list groundwater as their primary source.

The ME state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 30 of the 203 active systems in Hancock County (15%) are also owned by a local government.
