OTTAWA CO RWD #7 is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 500 people from groundwater.

As of August 1, 2026, its federal record holds 8 entries between 1999 and 2024, all of which EPA lists as closed.

Of the 8, 7 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 Lead and Copper Rule, and synthetic organic chemicals.
