AVON is one of 124 community water systems in South Dakota in the 501 to 3,300 people size category, serving 590 people from surface water.
As of August 1, 2026, its federal record holds 3 entries between 1976 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
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 Total Coliform Rules.
