What Makes Vernal's Water Unique?
Local geology and source profile
Vernal, Utah, in Uintah County — the Uintah County seat adjacent to Naples and Jensen in the Uinta Basin of northeast Utah — receives its water from the City of Vernal Water Department, drawing from Ashley Creek and deep artesian wells through the northeast Utah distribution.
The extremely hard 335.5 mg/L hardness and very high TDS of 1033.6 mg/L reflect the Uintah County Uinta Basin supply's extreme evaporitic-calcareous character — the Eocene Green River Formation is one of the most evaporitic formations in the American West, with thick oil shale, halite, and carbonate beds; the Cretaceous Mancos Shale contributes additional calcareous and sulfate mineral content from the Cretaceous seaway deposits (compare Naples UT: 329/1014 in Uintah County comparable; Jensen UT: 341/1052 in Uintah County comparable; Vernal consistent extremely hard from the same Uintah County Ashley Creek Green River Formation Eocene evaporitic supply). The Uinta Basin supply — Eocene Green River Formation (evaporitic calcareous — primary hardness contributor), Cretaceous Mancos Shale (calcareous — secondary contributor), and Quaternary Uinta Basin alluvium (evaporitic — TDS contributor).
At 335.5 mg/L with TDS 1034, Vernal's water is extremely hard — a whole-house water softener is essential. A reverse osmosis system is strongly recommended for drinking due to the very high TDS. The PFAS level of 4.6 ppt is moderate — manageable given the challenging water profile.
Geology & Source: Vernal in Uintah County draws from the Vernal City Water on Ashley Creek blend (Uintah County, northeast Utah) — the Uinta Basin at Uintah County draws from Eocene Green River Formation (evaporitic calcareous) and Cretaceous Mancos Shale (calcareous) — Utah Uintah County Ashley Creek Green River Formation Eocene evaporitic supply produces extremely hard water at 335.5 mg/L with TDS 1033.6 mg/L.
