Alpine Water Hardness & Quality Report (2026)

Alpine, Utah, in Utah County — a Utah County city adjacent to American Fork and Cedar Hills at the north Wasatch Range foothills — receives its water from the Alpine City Water Department, drawing from the Lone Peak watershed and local wells through the north Utah Valley distribution.

The very hard 294 mg/L hardness and very high TDS of 834.5 mg/L reflect the Utah County north Wasatch supply's very hard calcareous-evaporitic character — the Precambrian Lone Peak Pluton provides insoluble dilution, while the Cambrian Tintic Formation contributes calcareous mineral content; Alpine's groundwater wells concentrate elevated evaporitic mineral content from the Lake Bonneville lakebed sediments (compare American Fork UT: 289/820 in Utah County comparable; Cedar Hills UT: 237/592 in Utah County comparable; Alpine draws from deeper wells with higher evaporitic concentration). The Lone Peak watershed — Precambrian Lone Peak Pluton (insoluble — primary dilutant), Cambrian Tintic Formation (calcareous evaporitic — primary hardness contributor), and Quaternary Lake Bonneville sediment (evaporitic — TDS contributor).

At 294 mg/L with TDS 835, Alpine's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 4.0 ppt is moderate — a certified drinking water filter provides added protection. Review the Alpine City Water Department's annual water quality report.
