LOCKWOOD WATER AND SEWER DISTRICT is among the 22 largest community water systems in Montana, serving 5,900 people from surface water.
As of August 1, 2026, its federal record holds 3 entries between 2004 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.
Of the 3, 2 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 Consumer Confidence Rule, inorganic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
