RIVERSIDE COTTAGES is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, formerly serving 4 people from groundwater.

EPA's federal records list this system as inactive in 2020; the record below is historical.

As of August 1, 2026, its federal record holds 7 entries between 1998 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

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 the Total Coliform Rules, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and inorganic chemicals.
