INDIAN HILLS TC is one of 1,060 community water systems in Colorado in the 500 or fewer people size category, formerly serving 10 people from surface water.

EPA's federal records list this system as inactive in 2012; the record below is historical.

As of August 1, 2026, its federal record holds 22 entries between 1991 and 2008, all of which EPA lists as closed. Nothing has been added since 2008.

All 22 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, volatile organic chemicals, and the Surface Water Treatment Rules.
