DEER CREEK MOBILE HOME PARK is one of 1,084 community water systems in Montana in the 500 or fewer people size category, formerly serving 22 people from groundwater.
EPA's federal records list this system as inactive in 2022; the record below is historical.
As of August 1, 2026, its federal record holds 40 entries between 1992 and 1999, all of which EPA lists as closed. Nothing has been added since 1999.
All 40 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 Lead and Copper Rule, and inorganic chemicals.
