EHRENBERG IMPROVEMENT DISTRICT is one of 272 community water systems in Arizona in the 501 to 3,300 people size category, serving 989 people from surface water.
As of August 1, 2026, its federal record holds 28 entries between 1987 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
All 28 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, synthetic organic chemicals, and the Radionuclides and Revised Rad Rule.
