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): CO0107702
System type: Community Water System
Population served: 150
Service connections: 63
Ownership: privately owned
Water source: surface water (rivers, lakes, or reservoirs)

SANS SOUCI COOPERATIVE is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, serving 150 people from surface water.

As of August 1, 2026, its federal record holds 63 entries between 1986 and 2026, all of which EPA lists as closed.

Of the 63, 46 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, the Surface Water Treatment Rules, and inorganic chemicals.
