IRONTON WATERWORKS is one of 1,289 community water systems in Wisconsin in the 500 or fewer people size category, serving 253 people from groundwater.

As of August 1, 2026, its federal record holds 18 entries between 1993 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.

Of the 18, 17 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 and the Total Coliform Rules.
