COTTONWOOD FALLS SUBD is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, formerly serving 16 people from groundwater.
EPA's federal records list this system as inactive in 2009; the record below is historical.
As of August 1, 2026, its federal record holds 23 entries between 1993 and 2009, all of which EPA lists as closed. Nothing has been added since 2009.
All 23 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.
