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.

As of August 1, 2026, EPA's federal records show 2 items for MANCOS RURAL WATER COMPANY that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

System facts

System ID (PWSID): CO0142600
System type: Community Water System
Population served: 1,300
Service connections: 723
Ownership: privately owned
Water source: surface water (rivers, lakes, or reservoirs)

MANCOS RURAL WATER COMPANY is one of 305 community water systems in Colorado in the 501 to 3,300 people size category, serving 1,300 people from surface water.

As of August 1, 2026, its federal record holds 74 entries between 1995 and 2025, of which 2 remain open; none are health-based.

Of the 74, 72 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, inorganic chemicals, and the Surface Water Treatment Rules.
