System facts

PONCA TRIBE OF OKLAHOMA is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 360 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 46 entries between 1993 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

Of the 46, 42 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 Total Coliform Rules, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
