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.

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.
