LONE MOUNTAIN MHP is one of 293 community water systems in Nevada in the 500 or fewer people size category, formerly serving 210 people from groundwater.
EPA's federal records list this system as inactive in 2022; the record below is historical.
As of August 1, 2026, its federal record holds 6 entries between 1985 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.
Of the 6, 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 Total Coliform Rules and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
