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.

SILE MDWCA Water System

Consumer Confidence Report status

SILE 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 1 item for SILE MDWCA 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 New Mexico’s official records. Always confirm current status with New Mexico before making decisions based on this information.

System facts

System ID (PWSID): NM3543723
System type: Community Water System
Population served: 154
Service connections: 55
Ownership: local government
Water source: groundwater (wells)

SILE MDWCA is one of 667 community water systems in New Mexico in the 500 or fewer people size category, serving 154 people from groundwater.

As of August 1, 2026, its federal record holds 38 entries between 2007 and 2023, of which 1 remains open; none are health-based.

Of the 38, 16 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 Public Notice Rule and Revised PN Rule, the Total Coliform Rules, and the Groundwater Rule.
