OSAGE CO RWD #21 is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 1,500 people from surface water.
As of August 1, 2026, its federal record holds 103 entries between 1992 and 2026, of which 1 health-based item remains open, alongside 25 other open entries.
Of the 103, 76 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 Surface Water Treatment Rules, the Public Notice Rule and Revised PN Rule, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
