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.

Consumer Confidence Report status

Casa Del Eco Mesa NTUA 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 Casa Del Eco Mesa NTUA.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026.

Always confirm current status with Navajo Nation before making decisions based on this information.

System facts

System ID (PWSID): NN4903074
System type: Community Water System
Population served: 211
Service connections: 55
Ownership: Native American tribal
Water source: groundwater (wells)

Casa Del Eco Mesa NTUA is one of 125 community water systems in Navajo Nation in the 500 or fewer people size category, serving 211 people from groundwater.

As of August 1, 2026, its federal record holds 81 entries between 2008 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.

Of the 81, 80 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 volatile organic chemicals, synthetic organic chemicals, and the Total Coliform Rules.
