South Jordan Heights Water Hardness & Quality Report (2026)

South Jordan Heights, Utah, in Salt Lake County — a south Salt Lake County community in the rapidly growing South Jordan area of the greater Salt Lake Valley (South Jordan has been one of Utah's fastest-growing communities — a major planned residential community south of Salt Lake City), a predominantly residential family community in the Utah Valley Wasatch Front corridor, adjacent to Herriman and Riverton in the south Salt Lake County suburban zone, and a diverse Salt Lake County LDS-majority community in the rapidly expanding south Salt Lake Valley — draws its municipal water supply from the Wasatch Front watershed via the Jordan Valley Water Conservancy District and South Jordan City Water. Water hardness in South Jordan Heights measures 349 mg/L — classified as extremely hard.

South Jordan Heights's extreme hardness reflects the south Salt Lake Valley's highly calcareous Wasatch Front Paleozoic carbonate geology. The Jordan Valley watershed and Utah Lake at South Jordan–Salt Lake County draws from: the Cambrian Ophir Formation and Tintic Quartzite (calcareous); the Ordovician Juab Limestone and Fish Haven Dolomite (highly calcareous Ordovician carbonate of the Wasatch Range); the Mississippian Redwall and Madison Limestone (extremely calcareous marine limestone of the Wasatch Range). Jordan Valley Water Conservancy District applies minimal softening, producing the extreme 349 mg/L — one of the hardest municipal supplies in the USA.

At 349 mg/L, South Jordan Heights residents face severe hard water challenges. Water softeners are essentially a standard fixture in this community. Jordan Valley Water Conservancy District consistently delivers water meeting all Utah DWQ and EPA Safe Drinking Water Act requirements.
