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

Colorado has 956 active transient non-community water systems, 43% of the state's 2,207 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 166 Colorado systems (7.5%) list groundwater under influence of surface water as their primary source.
