MIDVALE WATER AND SEWER DISTRICT is one of 1,084 community water systems in Montana in the 500 or fewer people size category, formerly serving 320 people from surface water.
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 4 entries between 1997 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.
Of the 4, 3 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 Lead and Copper Rule and the Total Coliform Rules.
