CHARLOTTE WATER WORKS is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, serving 401 people from groundwater.

As of August 1, 2026, its federal record holds 9 entries between 1988 and 2011, all of which EPA lists as closed. Nothing has been added since 2011.

Of the 9, 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, inorganic chemicals, and the Total Coliform Rules.
