Is CHANDLER required to publish a Consumer Confidence Report?

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

CHANDLER’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.

System facts

System ID (PWSID): OK1020702
System type: Community Water System
Population served: 3,142
Service connections: 1,500
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

CHANDLER is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, serving 3,142 people from surface water.

As of August 1, 2026, its federal record holds 72 entries between 1994 and 2025, of which 1 health-based item remains open, alongside 1 other open entry.

Of the 72, 14 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.
