OXBOW MINING WW is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, formerly serving 7 people from surface water.

EPA's federal records list this system as inactive in 2021; the record below is historical.

As of August 1, 2026, its federal record holds 27 entries between 1993 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.

Of the 27, 25 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, the Surface Water Treatment Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
