WINCHESTER is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 1,589 people from groundwater.
As of August 1, 2026, its federal record holds 2 entries between 1977 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
All 2 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 and the Radionuclides and Revised Rad Rule.
