TULSA is the second largest community water system in Oklahoma, serving 413,000 people from surface water.
As of August 1, 2026, its federal record holds 22 entries between 2017 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
All 22 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 and the Stage 1 Disinfectants and Disinfection Byproducts Rule.

What is a Consumer Confidence Report?
- A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. 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.
