KARVAL WATER USERS INC is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, serving 102 people from groundwater.
As of August 1, 2026, its federal record holds 7 entries between 1994 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 7, 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 inorganic chemicals, the Total Coliform Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
