MONTROSE WATER WORKS is one of 403 community water systems in Iowa in the 501 to 3,300 people size category, serving 738 people from surface water.
As of August 1, 2026, its federal record holds 3 entries between 1988 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.
All 3 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 inorganic chemicals and the Total Coliform Rules.
