LOUISVILLE is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 1,201 people from surface water.
As of August 1, 2026, its federal record holds 8 entries between 1997 and 2000, all of which EPA lists as closed. Nothing has been added since 2000.
Of the 8, 7 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 Total Coliform Rules, the Lead and Copper Rule, and the Consumer Confidence Rule.
