OTTAWA CO RWD # 1 is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 458 people from groundwater.

As of August 1, 2026, its federal record holds 27 entries between 2020 and 2024, all of which EPA lists as closed.

All 27 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 synthetic organic chemicals.

It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
