OSMOND I&S DISTRICT is one of 486 community water systems in Wyoming in the 500 or fewer people size category, serving 315 people from groundwater.
As of August 1, 2026, its federal record holds 6 entries between 1979 and 1982, all of which EPA lists as closed. Nothing has been added since 1982.
All 6 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 inorganic chemicals and the Radionuclides and Revised Rad Rule.
