Thief River Falls is one of 90 community water systems in Minnesota in the 3,301 to 10,000 people size category, serving 8,701 people from surface water.

As of August 1, 2026, its federal record holds 7 entries between 2017 and 2025, all of which EPA lists as closed.

Of the 7, 2 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 the Surface Water Treatment Rules and the Lead and Copper Rule.

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.
