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.

Consumer Confidence Report status

CADDO must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.

As of August 1, 2026, EPA's federal records show no open violations for CADDO.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Oklahoma’s official records. Always confirm current status with Oklahoma before making decisions based on this information.

System facts

System ID (PWSID): OK2000703
System type: Community Water System
Population served: 944
Service connections: 603
Ownership: local government
Water source: groundwater (wells)

CADDO is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 944 people from groundwater.

As of August 1, 2026, its federal record holds 50 entries between 1993 and 2024, all of which EPA lists as closed.

Of the 50, 48 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 Lead and Copper Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
