NASHUA WATER SUPPLY is one of 403 community water systems in Iowa in the 501 to 3,300 people size category, serving 1,551 people from groundwater.
As of August 1, 2026, its federal record holds 11 entries between 1994 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
Of the 11, 10 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, the Total Coliform Rules, and the Public Notice Rule and Revised PN Rule.
