OASIS MHP is one of 293 community water systems in Nevada in the 500 or fewer people size category, formerly serving 46 people from groundwater.
EPA's federal records list this system as inactive in 2025; the record below is historical.
As of August 1, 2026, its federal record holds 5 entries between 2000 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.
Of the 5, 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, the Lead and Copper Rule, and the Total Coliform Rules.
