GAVIN ESTATES is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, serving 52 people from groundwater.

As of August 1, 2026, its federal record holds 34 entries between 1980 and 2026, of which 4 remain open; none are health-based.

Of the 34, 31 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 Total Coliform Rules, and the Radionuclides and Revised Rad Rule.

It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
