CAVOUR is one of 583 community water systems in South Dakota in the 500 or fewer people size category, formerly serving 114 people from surface water.
EPA's federal records list this system as inactive in 2013; the record below is historical.
As of August 1, 2026, its federal record holds 8 entries between 1976 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.
All 8 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 volatile organic chemicals, the Radionuclides and Revised Rad Rule, and the Lead and Copper Rule.
