CRESCENT VALLEY WATER SYSTEM is one of 293 community water systems in Nevada in the 500 or fewer people size category, serving 340 people from groundwater.
As of August 1, 2026, its federal record holds 5 entries between 2005 and 2011, all of which EPA lists as closed. Nothing has been added since 2011.
Of the 5, 4 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, inorganic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
