What Makes Pahrump's Water Unique?
Local geology and source profile
Pahrump, Nevada, in Nye County — a major southwest Nevada desert valley community approximately 60 miles west of Las Vegas (Pahrump is the largest unincorporated community in Nevada by population — a significant Nevada desert community in the Pahrump Valley, known for its independent culture, legal brothels, and proximity to Death Valley National Park), home of the Valley Electric Association (a major Nevada rural electric cooperative), a community with strong ties to Las Vegas commuter and retiree populations, and a diverse Nye County community in the rapidly growing Mojave Desert corridor — draws its municipal water supply from the Pahrump Valley Alluvial Aquifer via the Utilities Inc. of Central Nevada. Water hardness in Pahrump measures 301 mg/L — classified as very hard.
Pahrump's very hard supply reflects the Pahrump Valley desert alluvial basin's highly calcareous geology. The Pahrump Valley Alluvial Aquifer draws from: the Quaternary caliche-cemented desert alluvial fan deposits from the Spring Mountains (highly calcareous caliche from extreme Mojave Desert evaporative concentration) and the Nopah Range; and the Mesozoic calcareous carbonate rock aquifer in the valley margins. Utilities Inc. applies minimal softening, producing the very hard 301 mg/L.
At 301 mg/L, Pahrump residents face severe hard water challenges. Weekly descaling and appliance protection measures are strongly recommended. Utilities Inc. of Central Nevada consistently delivers water meeting all Nevada DEP and EPA Safe Drinking Water Act requirements.
