WESTERN SKIES MOBILE CT is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 25 people from groundwater.

As of August 1, 2026, its federal record holds 9 entries between 1993 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

Of the 9, 5 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 Consumer Confidence Rule, the Total Coliform Rules, and the Lead and Copper Rule.

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.
