Cosmos is one of 330 community water systems in Minnesota in the 501 to 3,300 people size category, serving 513 people from groundwater.

As of August 1, 2026, its federal record holds 4 entries in 2021, all of which EPA lists as closed. Nothing has been added since 2021.

None of the 4 are monitoring or reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset; these involve water-quality, treatment, or public-notice findings instead. The record involves inorganic chemicals.

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.
