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

Missouri has 228 active non-transient non-community water systems, 7.7% of the state's 2,943 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,521 Missouri systems (86%) list groundwater as their primary source.
