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.

CITY OF OBRIEN Water System

Consumer Confidence Report status

CITY OF OBRIEN 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 CITY OF OBRIEN 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 Texas’s official records. Always confirm current status with Texas before making decisions based on this information.

System facts

System ID (PWSID): TX1040005
System type: Community Water System
Population served: 87
Service connections: 72
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

CITY OF OBRIEN is one of 4,188 community water systems in Texas in the 500 or fewer people size category, serving 87 people from surface water.

As of August 1, 2026, its federal record holds 80 entries between 1979 and 2025, of which 1 remains open; none are health-based.

Of the 80, 44 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 Public Notice Rule and Revised PN Rule, and the Total Coliform Rules.

Common questions

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