What Makes Gold Canyon's Water Unique?
Local geology and source profile
Gold Canyon, Arizona, in Pinal County — a Pinal County unincorporated community adjacent to Apache Junction and Queen Creek in the east Phoenix metro area — receives its water from the Arizona Water Company and local wells, drawing from the San Tan Valley/Queen Creek aquifer through the east Maricopa/Pinal County distribution.
The very hard 265.5 mg/L hardness and TDS of 656.1 mg/L reflect the Pinal County supply's very hard Sonoran Desert character — the Miocene Cloudland Formation and Quaternary Queen Creek Valley alluvium are calcareous-evaporitic formations in the Pinal County desert basin; Gold Canyon's groundwater wells draw from shallower Queen Creek Valley alluvium with somewhat lower mineral concentration than the deeper Gila Basin wells of nearby Gold Camp (compare Apache Junction AZ: 270/668 in Pinal County comparable; Gold Camp AZ: 381.5/1109 deeper Pinal County comparable; Gold Canyon consistent very hard from the same Pinal County Queen Creek Valley Miocene calcareous supply). The San Tan Valley/Queen Creek aquifer — Miocene Cloudland Formation (calcareous — secondary contributor), Quaternary Queen Creek Valley alluvium (calcareous evaporitic — primary hardness contributor), and Quaternary Pinal County piedmont alluvial fan (calcareous — TDS contributor).
At 265.5 mg/L with TDS 656, Gold Canyon's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 3.7 ppt is moderate — a certified drinking water filter provides added protection. Review the Arizona Water Company's annual water quality report.
Geology & Source: Gold Canyon in Pinal County draws from the SRP/Arizona Water/wells on the San Tan Valley aquifer (Pinal County, east Maricopa/Pinal County) — the Sonoran Desert at Pinal County draws from Miocene Cloudland Formation (calcareous) and Quaternary Queen Creek Valley alluvium (calcareous evaporitic) — Arizona Pinal County Queen Creek Valley Miocene calcareous supply produces very hard water at 265.5 mg/L with TDS 656.1 mg/L.
