CHATHAM is one of 225 community water systems in Illinois in the 10,001 to 100,000 people size category, serving 16,423 people from groundwater.
As of August 1, 2026, its federal record holds 13 entries between 1996 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.
Of the 13, 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 Consumer Confidence Rule, the Total Coliform Rules, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.

What is a Consumer Confidence Report?

EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
