SHEFFIELD is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 821 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 1994 and 2009, all of which EPA lists as closed. Nothing has been added since 2009.
Of the 4, 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 Consumer Confidence Rule, the Total Coliform Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
