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.

CIMARRON WATER SYSTEM Water System

Consumer Confidence Report status

CIMARRON WATER SYSTEM 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 2 items for CIMARRON WATER SYSTEM 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 New Mexico’s official records. Always confirm current status with New Mexico before making decisions based on this information.

System facts

System ID (PWSID): NM3526204
System type: Community Water System
Population served: 1,260
Service connections: 597
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

CIMARRON WATER SYSTEM is one of 140 community water systems in New Mexico in the 501 to 3,300 people size category, serving 1,260 people from surface water.

As of August 1, 2026, its federal record holds 114 entries between 1980 and 2025, of which 2 remain open; none are health-based.

Of the 114, 31 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 Surface Water Treatment Rules, and the Public Notice Rule and Revised PN Rule.

Common questions

Is CIMARRON WATER SYSTEM required to publish a Consumer Confidence Report?: Yes. CIMARRON WATER SYSTEM 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 CIMARRON WATER SYSTEM’s next Consumer Confidence Report due?: CIMARRON WATER SYSTEM’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does CIMARRON WATER SYSTEM have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 2 items for CIMARRON WATER SYSTEM 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.
