CHATHAM is one of 1,316 community water systems in Michigan in the 500 or fewer people size category, serving 300 people from groundwater.
As of August 1, 2026, its federal record holds 6 entries in 2023, all of which EPA lists as closed. Nothing has been added since 2023.
All 6 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 volatile organic chemicals and synthetic organic chemicals.

What is a Consumer Confidence Report?
- A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
