YARNELL WATER IMPROVEMENT ASSOCIATION is one of 272 community water systems in Arizona in the 501 to 3,300 people size category, serving 515 people from groundwater.
As of August 1, 2026, its federal record holds 6 entries between 1988 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.
Of the 6, 5 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 Lead and Copper Rule, and the Consumer Confidence Rule.
