Is LA MESA WATER COOP required to publish a Consumer Confidence Report?

Yes. LA MESA WATER COOP 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 LA MESA WATER COOP’s next Consumer Confidence Report due?

LA MESA WATER COOP’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.

LA MESA WATER COOP Water System

Consumer Confidence Report status

LA MESA WATER COOP 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 no open violations for LA MESA WATER COOP.

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): NM3500123
System type: Community Water System
Population served: 650
Service connections: 330
Ownership: privately owned
Water source: groundwater (wells)

LA MESA WATER COOP is one of 140 community water systems in New Mexico in the 501 to 3,300 people size category, serving 650 people from groundwater.

As of August 1, 2026, its federal record holds 80 entries between 1993 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.

Of the 80, 79 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 synthetic organic chemicals, volatile organic chemicals, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
