Is PECAN TREE WATER ASSN required to publish a Consumer Confidence Report?

Yes. PECAN TREE WATER ASSN 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 PECAN TREE WATER ASSN’s next Consumer Confidence Report due?

PECAN TREE WATER ASSN’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): OK2001475
System type: Community Water System
Population served: 22
Service connections: 29
Ownership: privately owned
Water source: groundwater (wells)

PECAN TREE WATER ASSN is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 22 people from groundwater.

As of August 1, 2026, its federal record holds 188 entries between 2006 and 2026, of which 1 health-based item remains open, alongside 4 other open entries.

Of the 188, 131 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 Radionuclides and Revised Rad Rule, the Total Coliform Rules, and volatile organic chemicals.

Common questions

Is PECAN TREE WATER ASSN required to publish a Consumer Confidence Report?: Yes. PECAN TREE WATER ASSN 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 PECAN TREE WATER ASSN’s next Consumer Confidence Report due?: PECAN TREE WATER ASSN’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does PECAN TREE WATER ASSN have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 1 open health-based violation for PECAN TREE WATER ASSN, alongside 4 other open items.
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.
