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.

System facts

System ID (PWSID): NM3520005
System type: Community Water System
Population served: 264
Service connections: 99
Ownership: privately owned
Water source: groundwater (wells)

LONGHORN ESTATES MDWCA is one of 667 community water systems in New Mexico in the 500 or fewer people size category, serving 264 people from groundwater.

As of August 1, 2026, its federal record holds 142 entries between 2001 and 2026, of which 10 health-based items remain open, alongside 15 other open entries.
