A 1 DISCOUNT WC is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, formerly serving 20 people from surface water.
EPA's federal records list this system as inactive in 2023; the record below is historical.
As of August 1, 2026, its federal record holds 9 entries between 2002 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
Of the 9, 4 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 Surface Water Treatment Rules.
