IOWA CITY WATER DEPARTMENT is among the 8 largest community water systems in Iowa, serving 68,753 people from surface water.

As of August 1, 2026, its federal record holds 33 entries between 1987 and 1996, all of which EPA lists as closed. Nothing has been added since 1996.

All 33 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 the Radionuclides and Revised Rad Rule.
