What Makes Kingman's Water Unique?
Local geology and source profile
Kingman, Arizona, the Mohave County seat — a major northwest Arizona Route 66 city (Kingman is the Mohave County seat — the principal city of northwest Arizona; Kingman is one of the most historically significant cities on historic Route 66 (the famous 'Main Street of America' — the original highway from Chicago to Los Angeles; Kingman is in the heart of Arizona's Route 66 corridor, and the Route 66 Museum in Kingman is one of the most important Route 66 heritage museums in the Southwest); Kingman is situated between Las Vegas and Phoenix in the northwest Arizona Mohave County basin, making it one of the most strategically located transportation hubs in the Arizona–Nevada–California tri-state corridor), birthplace of Clark Gable (the legendary 'King of Hollywood' — Clark Gable was born in Cadiz, Ohio, but married Carole Lombard in a ceremony in Kingman on March 29, 1939; the ceremony is commemorated in Kingman), a diverse Mohave County community with a significant retiree, Route 66 tourism, and working-class population, and a community gateway to the Hualapai Mountains — draws its municipal water supply from the Hualapai Valley Basin aquifer via the City of Kingman Water Division. Water hardness in Kingman measures 357 mg/L — classified as extremely hard.
Kingman's extremely hard supply reflects the northwest Arizona Mohave County closed-basin Basin and Range aquifer's highly calcareous limestone character. The Hualapai Valley Basin aquifer draws from the Precambrian Hualapai limestone and Triassic Moenkopi Formation (highly calcareous). Very limited softening produces the extreme 357 mg/L.
At 357 mg/L, Kingman residents face severe hard water challenges. Water softeners and regular appliance descaling are essential. City of Kingman Water Division consistently delivers water meeting all Arizona ADEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Hualapai Valley Basin aquifer via the City of Kingman Water Division — the Mohave County northwest Arizona Colorado Plateau Kingman corridor (Precambrian calcareous Hualapai limestone and Triassic calcareous Moenkopi Formation — the extremely calcareous northwest Arizona closed-basin Basin and Range aquifer; very limited softening); extremely hard at 357 mg/L in Mohave County.
