WINTERHAVEN WATER DEVELOPMENT is one of 272 community water systems in Arizona in the 501 to 3,300 people size category, serving 685 people from groundwater.
As of August 1, 2026, its federal record holds 8 entries between 1980 and 1987, all of which EPA lists as closed. Nothing has been added since 1987.
All 8 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 and the Radionuclides and Revised Rad Rule.
