Yes. CASSANDRA WATER SYSTEM 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 CASSANDRA WATER SYSTEM’s next Consumer Confidence Report due?

CASSANDRA WATER SYSTEM’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.

System facts

System ID (PWSID): NM3500330
System type: Community Water System
Population served: 34
Service connections: 11
Ownership: privately owned
Water source: groundwater (wells)

CASSANDRA WATER SYSTEM is one of 667 community water systems in New Mexico in the 500 or fewer people size category, serving 34 people from groundwater.

As of August 1, 2026, its federal record holds 113 entries between 2000 and 2025, of which 2 health-based items remain open, alongside 36 other open entries.

Of the 113, 49 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 Total Coliform Rules, the Public Notice Rule and Revised PN Rule, and the Radionuclides and Revised Rad Rule.
