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.

System facts

System ID (PWSID): OK2006720
System type: Community Water System
Population served: 6,899
Service connections: 1,067
Ownership: local government
Water source: groundwater (wells)

SEMINOLE is one of 106 community water systems in Oklahoma in the 3,301 to 10,000 people size category, serving 6,899 people from groundwater.

As of August 1, 2026, its federal record holds 37 entries between 2003 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

Of the 37, 36 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.
