Is OSAGE CO RWD #20 (HULAH) required to publish a Consumer Confidence Report?

Yes. OSAGE CO RWD #20 (HULAH) 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 OSAGE CO RWD #20 (HULAH)’s next Consumer Confidence Report due?

OSAGE CO RWD #20 (HULAH)’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.

Consumer Confidence Report status

OSAGE CO RWD #20 (HULAH) 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 1 item for OSAGE CO RWD #20 (HULAH) that is 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): OK1021410
System type: Community Water System
Population served: 350
Service connections: 131
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

OSAGE CO RWD #20 (HULAH) is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 350 people from surface water.

As of August 1, 2026, its federal record holds 81 entries between 1993 and 2025, of which 1 remains open; none are health-based.

Of the 81, 11 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 2 Disinfectants and Disinfection Byproducts Rule, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Surface Water Treatment Rules.

Common questions

Is OSAGE CO RWD #20 (HULAH) required to publish a Consumer Confidence Report?: Yes. OSAGE CO RWD #20 (HULAH) 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 OSAGE CO RWD #20 (HULAH)’s next Consumer Confidence Report due?: OSAGE CO RWD #20 (HULAH)’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does OSAGE CO RWD #20 (HULAH) have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 1 item for OSAGE CO RWD #20 (HULAH) that is 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.
