What Makes Goodyear's Water Unique?
Local geology and source profile
Goodyear, Arizona — a rapidly growing West Valley city in west Maricopa County (home of the Goodyear Ballpark spring training complex) — draws its municipal water supply through the City of Goodyear Water Services Division, sourcing from Central Arizona Project (CAP) Colorado River deliveries and local Hassayampa Plain alluvial groundwater wells in the west Maricopa County basin. Goodyear is one of the fastest-growing cities in the United States. Water hardness in Goodyear reaches 401.5 mg/L — classified as extremely hard, one of the highest municipal water hardness readings in Arizona.
Goodyear's extreme hardness reflects the west Maricopa County water supply's dual calcareous burden. Colorado River (CAP aqueduct) water at the west Phoenix/Goodyear delivery point carries heavy mineral loading from the entire Colorado Plateau calcareous formation sequence (Kaibab Limestone, Redwall Limestone, Bright Angel Shale, Moenkopi Formation — thousands of feet of carbonate-bearing rock in the Grand Canyon and lower Colorado reaches). More critically, Hassayampa Plain alluvial groundwater in west Maricopa County is extraordinarily hard — the Hassayampa Alluvial Basin is flanked by Tertiary gypsiferous alluvial fans from the White Tank Mountains (Precambrian White Tank Granite weathered in a Sonoran Desert evaporite environment), producing groundwater with extremely high dissolved calcium and sulfate.
At 401.5 mg/L, Goodyear residents face severe hard water challenges throughout the home. Scale deposits form within days on all fixtures, appliances, and shower surfaces. Descaling with commercial citric acid products must be performed weekly or bi-weekly. Water heaters need semi-annual professional inspection and descaling. City of Goodyear Water Services consistently delivers water meeting all Arizona ADEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: Mixed supply from Colorado River (CAP aqueduct) and local West Maricopa–Hassayampa alluvial basin groundwater via the City of Goodyear Water Services Division — the highly calcareous Lower Colorado River Basin and the Sonoran Desert gypsiferous alluvial plain of west Maricopa County; extremely hard supply at 401.5 mg/L — among the hardest municipal water supplies in Arizona.
