SOUTHSIDE PUBLIC WATER SUPPLY is one of 1,084 community water systems in Montana in the 500 or fewer people size category, serving 306 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 1994 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.
All 4 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 and inorganic chemicals.
