Murray Water Hardness & Quality Report (2026)

Murray City Water, operated by the City of Murray in Salt Lake County, Utah, serves approximately 36,000 residents across roughly 6 square miles of the urban Salt Lake Valley. The utility sources its water from a combination of local groundwater wells drawing from the Salt Lake Valley valley-fill aquifer and treated surface water, with primary production from wells in the Murray area. Treatment facilities employ filtration, chlorination, and corrosion control, with blending of sources used to optimize quality. Annual pumping volumes have reached over 3.2 billion gallons in recent years.

The watershed encompasses the Salt Lake Valley basin, fed by mountain runoff from the Wasatch Front but primarily reliant on groundwater recharged through alluvial fans and basin-fill sediments. Key geological features include Quaternary unconsolidated gravels, sands, and clays overlying consolidated Tertiary sedimentary rocks and older carbonate formations — limestone and dolomite from the Pennsylvanian and Permian periods. Groundwater interacts extensively with these calcium- and magnesium-bearing rocks, dissolving minerals that produce the characteristically hard supply measured at 194.5 mg/L.

Very hard water in Murray causes significant scale buildup in pipes, water heaters, dishwashers, and washing machines — water heaters can lose 10–20% efficiency from mineral deposits alone. Faucets and heating elements are most affected, often requiring frequent descaling or replacement. Regular flushing of water heaters, scale inhibitors, and sediment filters all help; a water softener is highly recommended to protect plumbing and improve soap efficiency. The 2022 Consumer Confidence Report confirms compliance with EPA standards for all primary contaminants, with lead and copper levels below action limits. Iron and natural deposit erosion products are noted at safe levels; general disinfection byproducts are monitored and controlled.
