System type: Community Water System
Population served: 1,387
Service connections: 525

ROSICLARE is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, formerly serving 1,387 people from surface water.

EPA's federal records list this system as inactive in 2023; the record below is historical.

As of August 1, 2026, its federal record holds 31 entries between 1977 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

Of the 31, 28 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Lead and Copper Rule.
