MAYFAIR SUBDIVISION is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, serving 98 people from groundwater.
As of August 1, 2026, its federal record holds 13 entries between 1977 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
All 13 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 volatile organic chemicals, inorganic chemicals, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
