Consumer Confidence Report status
GAVIN ESTATES must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.
As of August 1, 2026, EPA's federal records show 4 items for GAVIN ESTATES that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Iowa’s official records. Always confirm current status with Iowa before making decisions based on this information.

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.
