GREENFIELD MUNICIPAL UTILITIES is one of 403 community water systems in Iowa in the 501 to 3,300 people size category, serving 2,227 people from surface water.
As of August 1, 2026, its federal record holds 4 entries between 2004 and 2012, all of which EPA lists as closed. Nothing has been added since 2012.
Of the 4, 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 Stage 1 Disinfectants and Disinfection Byproducts Rule and the Surface Water Treatment Rules.
