CORALVILLE LAKE TERRACE is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, serving 340 people from groundwater.
As of August 1, 2026, its federal record holds 36 entries between 1980 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.
Of the 36, 26 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, inorganic chemicals, and the Consumer Confidence Rule.
