AURORA is the second largest community water system in Illinois, serving 183,000 people from surface water.
As of August 1, 2026, its federal record holds 6 entries between 1977 and 2004, all of which EPA lists as closed. Nothing has been added since 2004.
Of the 6, 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 Radionuclides and Revised Rad Rule, the Total Coliform Rules, and the Lead and Copper Rule.

What is a Consumer Confidence Report?
