Riverton Water Hardness & Quality Report (2026)

Riverton, Utah, in Salt Lake County — a rapidly growing south Salt Lake Valley community, one of the fastest-growing communities in Utah, a major Wasatch Front south suburban community adjacent to Herriman and South Jordan, home of numerous master-planned communities in the south Salt Lake Valley corridor, and a major Church of Jesus Christ of Latter-day Saints (LDS) suburban family community in the Wasatch Front growth zone — draws its municipal water supply from the JVWCD Provo River and Cottonwood Canyon supply via the City of Riverton Water Division. Water hardness in Riverton measures 254 mg/L — classified as very hard.

Riverton's very hard supply reflects the Salt Lake Valley's calcareous Wasatch Mountain and Lake Bonneville geology. The JVWCD supply draws from: the Provo River watershed (Uinta Mountains Precambrian calcareous quartzite and Wasatch Range calcareous Cambrian–Ordovician limestone — the Ophir Formation and Maxfield Limestone calcareous carbonate zones); and the Pleistocene Lake Bonneville calcareous lacustrine deposits (the southwest Salt Lake Valley sits on former Lake Bonneville lakebed — calcareous marl and evaporite-enriched calcareous lake sediment). The JVWCD calcareous Wasatch supply and Lake Bonneville sediment contribute to the very hard 254 mg/L at Riverton.

At 254 mg/L, Riverton residents face severe hard water challenges. Weekly descaling and appliance protection measures are strongly recommended. City of Riverton Water Division consistently delivers water meeting all Utah DDW and EPA Safe Drinking Water Act requirements.
