What does “transient non-community water system” mean?
A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Wyoming has 352 active transient non-community water systems, 45% of the state's 775 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. 24 Wyoming systems (3.1%) list groundwater under influence of surface water as their primary source.
