SOUTHERN SIOUX COUNTY RURAL WATER is one of 91 community water systems in Iowa in the 3,301 to 10,000 people size category, serving 5,420 people from groundwater.

As of August 1, 2026, its federal record holds 9 entries between 1981 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.

Of the 9, 8 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.
