ROSELLE is one of 225 community water systems in Illinois in the 10,001 to 100,000 people size category, serving 22,897 people from surface water.
As of August 1, 2026, its federal record holds 7 entries between 1977 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 7, 4 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 Lead and Copper Rule, the Radionuclides and Revised Rad Rule, and the Consumer Confidence Rule.
