DENVER HILLS SUBDIVISION is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 50 people from groundwater.
EPA's federal records list this system as inactive in 2010; the record below is historical.
As of August 1, 2026, its federal record holds 3 entries between 2005 and 2009, all of which EPA lists as closed. Nothing has been added since 2009.
All 3 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 Radionuclides and Revised Rad Rule and the Total Coliform Rules.
