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

Oregon has 346 active non-transient non-community water systems, 14% of the state's 2,536 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,175 Oregon systems (86%) list groundwater as their primary source.
