OKAWVILLE is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 1,457 people from surface water.
As of August 1, 2026, its federal record holds 6 entries between 1977 and 2026, all of which EPA lists as closed.
Of the 6, 2 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Surface Water Treatment Rules.
