PINE TREE MOBILE PARK Water System

Inactive system

System facts

System ID (PWSID): MT0001364
System type: Community Water System
Population served: 50
Service connections: 26
Ownership: privately owned
Water source: groundwater (wells)

PINE TREE MOBILE PARK is one of 1,084 community water systems in Montana in the 500 or fewer people size category, formerly serving 50 people from groundwater.

EPA's federal records list this system as inactive in 2005; the record below is historical.

As of August 1, 2026, its federal record holds 71 entries between 1995 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.

Of the 71, 70 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 synthetic organic chemicals, volatile organic chemicals, and the Total Coliform Rules.
