DOWNERS GROVE is one of 225 community water systems in Illinois in the 10,001 to 100,000 people size category, serving 49,425 people from surface water.
As of August 1, 2026, its federal record holds 5 entries between 1994 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.
Of the 5, 3 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 Consumer Confidence Rule, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
