OJO SARCO MDWCA is one of 667 community water systems in New Mexico in the 500 or fewer people size category, serving 225 people from groundwater.

As of August 1, 2026, its federal record holds 6 entries between 2002 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 6, 2 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 Consumer Confidence Rule, the Public Notice Rule and Revised PN Rule, and the Total Coliform Rules.

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.
