MOUNTAIN VALLEY ESTATES is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, serving 200 people from groundwater.
As of August 1, 2026, its federal record holds 8 entries between 1991 and 1995, all of which EPA lists as closed. Nothing has been added since 1995.
All 8 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 Total Coliform Rules, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
