MOUNTAIN HOME AIR FORCE BASE is one of 32 community water systems in Idaho in the 3,301 to 10,000 people size category, serving 7,500 people from groundwater.
As of August 1, 2026, its federal record holds 49 entries between 2011 and 2024, all of which EPA lists as closed.
Of the 49, 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, synthetic organic chemicals, and 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.
