What Makes North Salt Lake's Water Unique?
Local geology and source profile
North Salt Lake, Utah, in Davis County — a Davis County city on the Wasatch Front between Salt Lake City and Bountiful, part of the rapidly growing Davis County corridor adjacent to the Great Salt Lake — receives its municipal water from the North Salt Lake City Water Division or Davis and Weber Counties Canal Company, drawing from the Jordan River system (conveying Utah Lake water), local Wasatch Front streams, and possibly the Central Utah Water Conservancy District (CUWCD) Provo River deliveries.
The extremely hard 336 mg/L hardness and very high TDS of 1047 mg/L reflect the Great Salt Lake Basin's extraordinary evaporite and carbonate geology. The Wasatch Front corridor's water supply sources drain the Uinta Mountains (quartzite and carbonate) and the Wasatch Range (Paleozoic Oquirrh Formation carbonate, Permian and Triassic evaporite-bearing formations). The Jordan River conveys Utah Lake water — Utah Lake being a shallow lake with extremely high dissolved minerals from the carbonate and evaporite geology of the central Utah basin. The Great Salt Lake basin's atmospheric dust and evaporite terrain further enrich all water sources with calcium, magnesium, sulfate, and bicarbonate — producing TDS of over 1000 mg/L, among the highest in any American municipal supply.
At 336 mg/L with TDS 1047 mg/L — nearly 3× the EPA aesthetic TDS guideline — North Salt Lake's water is extremely hard. A whole-house water softener is essential and kitchen reverse osmosis filtration is strongly recommended for all drinking and cooking water. The PFAS level of 4.7 ppt warrants a certified drinking water filter — Hill Air Force Base (Davis County — a major Air Force Materiel Command AFFF-using base) is the primary PFAS source for the Davis County water system.
Geology & Source: North Salt Lake in Davis County draws from North Salt Lake City Water on the Jordan River or Davis and Weber Counties Canal (Wasatch Front snowmelt) — the Wasatch Front supply drains Paleozoic Oquirrh carbonate and Permian-Triassic evaporite formations of the Great Salt Lake Basin — Wasatch Front carbonate-evaporite drainage produces extremely hard water at 336 mg/L with very high TDS 1047 mg/L in this Davis County Utah city.
