MONTEZUMA MUNI WATER SUPPLY is one of 403 community water systems in Iowa in the 501 to 3,300 people size category, serving 1,545 people from groundwater.

As of August 1, 2026, its federal record holds 9 entries between 1982 and 1988, all of which EPA lists as closed. Nothing has been added since 1988.

All 9 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 Lead and Copper Rule.
