MILL CITY WATER DEPARTMENT is one of 203 community water systems in Oregon in the 501 to 3,300 people size category, serving 1,830 people from groundwater.

As of August 1, 2026, its federal record holds 48 entries between 1976 and 2012, all of which EPA lists as closed. Nothing has been added since 2012.

Of the 48, 46 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, inorganic chemicals, and the Surface Water Treatment Rules.
