What Makes Eloy's Water Unique?
Local geology and source profile
Eloy, Arizona, in Pinal County — a Pinal County city adjacent to Casa Grande and Picacho in the central Arizona Santa Cruz Valley — receives its municipal water from the City of Eloy Water Division, drawing from local groundwater wells in the Santa Cruz Valley Basin and supplemented by the Central Arizona Project (CAP) (Colorado River water) through the Eloy treatment system.
The moderately hard 141 mg/L hardness and TDS of 282.8 mg/L reflect the central Arizona Basin and Range alluvial aquifer's moderate mineralization. The Santa Cruz Valley Basin aquifer is developed in Quaternary basin fill alluvium and Pliocene lacustrine sediment (calcareous) over Tertiary volcanic-sedimentary Basin and Range deposits. The CAP Colorado River supply contribution adds some additional hardness and TDS.
At 141 mg/L, Eloy's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 2.3 ppt is very low — the Pinal County rural central Arizona agricultural setting, limited industrial PFAS point sources in the Eloy area, and the natural aquifer filtration in the Santa Cruz Valley produce Eloy's very clean PFAS profile.
Geology & Source: Eloy in Pinal County draws from the City of Eloy Water on the Santa Cruz Valley aquifer and CAP (Pinal County, central Arizona) — the aquifer is developed in Quaternary alluvium and Pliocene basin fill over the Basin and Range (calcareous) — Arizona Pinal County Santa Cruz Valley alluvial-CAP supply produces moderately hard water at 141 mg/L with TDS 282.8 mg/L in this Pinal County Arizona city.
