Is DELAWARE required to publish a Consumer Confidence Report?

Yes. DELAWARE 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 DELAWARE’s next Consumer Confidence Report due?

DELAWARE’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.

DELAWARE Water System

Consumer Confidence Report status

DELAWARE 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 7 items for DELAWARE 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): OK1021502
System type: Community Water System
Population served: 456
Service connections: 358
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

DELAWARE is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 456 people from surface water.

As of August 1, 2026, its federal record holds 89 entries between 2003 and 2025, of which 7 remain open; none are health-based.

Of the 89, 45 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 Surface Water Treatment Rules, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Public Notice Rule and Revised PN Rule.

Common questions

Is DELAWARE required to publish a Consumer Confidence Report?: Yes. DELAWARE 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 DELAWARE’s next Consumer Confidence Report due?: DELAWARE’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does DELAWARE have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 7 items for DELAWARE 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.
