SHADY NOOK TRAILER COURT is one of 1,084 community water systems in Montana in the 500 or fewer people size category, formerly serving 34 people from groundwater.

EPA's federal records list this system as inactive in 2018; the record below is historical.

As of August 1, 2026, its federal record holds 47 entries between 1994 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.

Of the 47, 42 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, inorganic chemicals, and synthetic organic chemicals.
