WINDSOR is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 1,200 people from surface water.
As of August 1, 2026, its federal record holds 10 entries between 1977 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 10, 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 Lead and Copper Rule, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Consumer Confidence Rule.
