What does “non-transient non-community water system” mean?

Minnesota has 470 active non-transient non-community water systems, 7.3% of the state's 6,465 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,261 Minnesota systems (97%) list groundwater as their primary source.
