ARDMORE is among the 23 largest community water systems in Oklahoma, serving 24,893 people from surface water.

As of August 1, 2026, its federal record holds 11 entries between 1993 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

Of the 11, 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 the Stage 1 Disinfectants and Disinfection Byproducts Rule, synthetic organic chemicals, and the Surface Water Treatment Rules.
