HARTFORD WATER WORKS is one of 403 community water systems in Iowa in the 501 to 3,300 people size category, formerly serving 759 people from groundwater.

EPA's federal records list this system as inactive in 2007; the record below is historical.

As of August 1, 2026, its federal record holds 7 entries between 1979 and 2004, all of which EPA lists as closed. Nothing has been added since 2004.

Of the 7, 5 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, the Radionuclides and Revised Rad Rule, and the Lead and Copper Rule.
