KALAMAZOO is the third largest community water system in Michigan, serving 192,992 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 2015 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.
Of the 3, 1 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 Lead and Copper Rule and the Radionuclides and Revised Rad Rule.
