CAVE-IN-ROCK is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, serving 228 people from groundwater.
As of August 1, 2026, its federal record holds 20 entries between 1977 and 1999, all of which EPA lists as closed. Nothing has been added since 1999.
All 20 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 Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
