Is BARNSDALL required to publish a Consumer Confidence Report?

Yes. BARNSDALL is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.

When is BARNSDALL’s next Consumer Confidence Report due?

BARNSDALL’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.

BARNSDALL Water System

Consumer Confidence Report status

BARNSDALL 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 4 items for BARNSDALL that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

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): OK1021304
System type: Community Water System
Population served: 1,243
Service connections: 502
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

BARNSDALL is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 1,243 people from surface water.

As of August 1, 2026, its federal record holds 365 entries between 1991 and 2026, of which 4 remain open; none are health-based.

Of the 365, 96 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 the Stage 1 Disinfectants and Disinfection Byproducts Rule, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Surface Water Treatment Rules.

Common questions

Is BARNSDALL required to publish a Consumer Confidence Report?: Yes. BARNSDALL is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is BARNSDALL’s next Consumer Confidence Report due?: BARNSDALL’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does BARNSDALL have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 4 items for BARNSDALL that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
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.
