REGIONAL WATER is one of 91 community water systems in Iowa in the 3,301 to 10,000 people size category, serving 4,132 people from surface water.
As of August 1, 2026, its federal record holds 3 entries between 1992 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.
Of the 3, 2 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 Groundwater Rule.

What is a Consumer Confidence Report?

It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
