SHAWNEE WCA is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, serving 50 people from surface water.

As of August 1, 2026, its federal record holds 20 entries between 1991 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 20, 18 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 inorganic chemicals, volatile organic chemicals, and the Surface Water Treatment Rules.

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.
