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): OK2004207
System type: Community Water System
Population served: 8,907
Service connections: 4,424
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

LOGAN CO RWD #1 is one of 106 community water systems in Oklahoma in the 3,301 to 10,000 people size category, serving 8,907 people from surface water.

As of August 1, 2026, its federal record holds 32 entries between 2007 and 2024, all of which EPA lists as closed.
