MANSFIELD is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 939 people from groundwater.
As of August 1, 2026, its federal record holds 10 entries between 1977 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.
Of the 10, 5 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.
