Salt Lake City's 2024 report lists calculated hardness of roughly 7.7 to 11.4 grains per gallon (132 to 194 ppm), placing Millcreek's water in the moderately hard to hard range.
What stands out
Where it comes from
Salt Lake City draws from mountain streams in protected Wasatch watersheds (City Creek, Parleys, Big Cottonwood, and Little Cottonwood creeks), groundwater wells and springs, and treated water purchased from the Metropolitan Water District of Salt Lake and Sandy and the Jordan Valley Water Conservancy District.
Hardness in grains
The report lists calculated hardness of about 7.7 to 11.4 grains per gallon across its treatment plants (132 to 194 ppm), which falls in the moderately hard to hard range. That is the natural mineral content carried from the source water.
What was measured
Total dissolved solids ran 230 to 328 ppm, within the 2000 ppm secondary standard. Disinfection by-products were below federal limits (TTHMs roughly 14 to 48 ppb against an 80 ppb limit, HAA5 roughly 21 to 40 ppb against a 60 ppb limit), with a chlorine residual near 0.8 ppm.

What helps
What we would do about it.
A drinking-water ionizer at the sink gives you cleaner, better tasting alkaline water and cuts the chlorine taste that comes with treated municipal supply, while a whole-home salt-free conditioner helps manage the scale that hard water leaves behind.
