AUBURN is one of 248 community water systems in Illinois in the 3,301 to 10,000 people size category, serving 4,574 people from surface water.
As of August 1, 2026, its federal record holds 11 entries between 1994 and 2025, all of which EPA lists as closed.
Of the 11, 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.
