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.

UPPER ARROYO HONDO MDWCA Water System

Consumer Confidence Report status

UPPER ARROYO HONDO MDWCA 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 6 items for UPPER ARROYO HONDO MDWCA 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): NM3507829
System type: Community Water System
Population served: 195
Service connections: 65
Ownership: local government
Water source: groundwater (wells)

UPPER ARROYO HONDO MDWCA is one of 667 community water systems in New Mexico in the 500 or fewer people size category, serving 195 people from groundwater.

As of August 1, 2026, its federal record holds 76 entries between 2002 and 2023, of which 6 remain open; none are health-based.

Of the 76, 21 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 Public Notice Rule and Revised PN Rule, and the Consumer Confidence Rule.

Common questions

Is UPPER ARROYO HONDO MDWCA required to publish a Consumer Confidence Report?: Yes. UPPER ARROYO HONDO MDWCA 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 UPPER ARROYO HONDO MDWCA’s next Consumer Confidence Report due?: UPPER ARROYO HONDO MDWCA’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does UPPER ARROYO HONDO MDWCA have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show 6 items for UPPER ARROYO HONDO MDWCA 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.
