RIDGEWATER IMPROVEMENT DISTRICT is one of 486 community water systems in Wyoming in the 500 or fewer people size category, serving 218 people from surface water.
As of August 1, 2026, its federal record holds 3 entries between 1980 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.
All 3 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Radionuclides and Revised Rad Rule and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
