SOUTHWEST MHP is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 100 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 34 entries between 2008 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
Of the 34, 32 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, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
