COAL VALLEY WATER DISTRICT is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, serving 240 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1991 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.
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 the Total Coliform Rules and the Lead and Copper Rule.
