ANN ARBOR ESTATES is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 228 people from surface water.
EPA's federal records list this system as inactive in 2019; the record below is historical.
As of August 1, 2026, its federal record holds 11 entries between 2008 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
Of the 11, 9 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 the Stage 1 Disinfectants and Disinfection Byproducts Rule, the Total Coliform Rules, and the Consumer Confidence Rule.
