OTTAWA CO RWD #6 is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 560 people from groundwater.

As of August 1, 2026, its federal record holds 44 entries between 1999 and 2025, of which 1 remains open; none are health-based.

Of the 44, 43 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 volatile organic chemicals, the Radionuclides and Revised Rad Rule, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
