EPCOR - ANTHEM is one of 67 community water systems in Arizona in the 10,001 to 100,000 people size category, serving 23,826 people from surface water.
As of August 1, 2026, its federal record holds 3 entries between 2002 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.
Of the 3, 2 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 volatile organic chemicals, the Radionuclides and Revised Rad Rule, and the Consumer Confidence Rule.
