CASCADE MUNICIPAL WATER SUPPLY is one of 403 community water systems in Iowa in the 501 to 3,300 people size category, serving 2,386 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1988 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.
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 the Total Coliform Rules, synthetic organic chemicals, and inorganic chemicals.
