Is OTTAWA CO RWD #5 required to publish a Consumer Confidence Report?

Yes. OTTAWA CO RWD #5 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 OTTAWA CO RWD #5’s next Consumer Confidence Report due?

OTTAWA CO RWD #5’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.

OTTAWA CO RWD #5 Water System

Consumer Confidence Report status

OTTAWA CO RWD #5 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 OTTAWA CO RWD #5.

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): OK2005840
System type: Community Water System
Population served: 750
Service connections: 493
Ownership: local government
Water source: groundwater (wells)

OTTAWA CO RWD #5 is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 750 people from groundwater.

As of August 1, 2026, its federal record holds 90 entries between 1993 and 2025, all of which EPA lists as closed.

Of the 90, 86 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, synthetic organic chemicals, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
