Salt Lake County is home to about 1.2 million residents, with water supplied by a complex network of providers including Salt Lake City Public Utilities, Jordan Valley Water Conservancy District, and numerous smaller cities and improvement districts. Water comes from mountain reservoirs in the Wasatch Range, the Jordan River, and groundwater wells in the Salt Lake Valley. The snowpack-dependent supply is increasingly under pressure from drought and population growth.
The Wasatch mountain watersheds provide high-quality source water, but the Salt Lake Valley's growing population and urban footprint add contaminants to groundwater and the Jordan River. UCMR5 data shows PFAS detections in several county water systems. Salt Lake City International Airport and the former military facilities at Camp Williams and the Tooele Army Depot (in neighboring Tooele County, but hydrologically connected) are potential PFAS sources.
According to the Utah Department of Environmental Quality, seven public water systems in Salt Lake County reported PFAS detections during the most recent monitoring period. Utah has not adopted state-specific PFAS MCLs, relying on federal standards.
Mountain source water is generally cleaner than valley groundwater in this county. If your provider draws primarily from wells in the Salt Lake Valley floor, you may see a different contaminant profile than communities on Wasatch canyon water.
