What Makes Farragut's Water Unique?
Local geology and source profile
Farragut, Tennessee, in Knox County — a prestigious western Knoxville suburb named for Civil War Admiral David Glasgow Farragut (born near the current town site), one of the wealthiest and fastest-growing communities in the Knoxville metropolitan area along the Turkey Creek commercial corridor — receives its municipal water from the Knoxville Utilities Board (KUB), which draws from the Tennessee Valley Authority (TVA) reservoir system — primarily Fort Loudoun Lake (Tennessee River) or Melton Hill Lake (Clinch River) — through KUB's distribution network serving western Knox County.
The moderately hard 157 mg/L hardness and TDS of 319.4 mg/L reflect the Tennessee River system's Valley and Ridge carbonate geology. The Tennessee River at Knox County drains the Valley and Ridge Province — the classic Appalachian fold-and-thrust belt folded carbonate sequence including the Ordovician Knox Dolomite (a massive, thick dolomite formation dominating the Valley and Ridge subsurface), the Cambrian Conasauga Formation (limestone and shale), and other Cambrian–Ordovician carbonate units. TVA's Fort Loudoun and Melton Hill reservoirs integrate drainage from these prolific carbonate terrains throughout the upper Tennessee Valley, consistently producing moderately hard reservoir water that KUB treats and distributes throughout western Knox County.
At 157 mg/L, Farragut's water is moderately hard — consistent with the Tennessee River Valley supply profile. Scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling of heating appliances is the standard schedule. The PFAS level of 5.2 ppt warrants a certified drinking water filter — the Tennessee Valley's legacy chemical industry (Eastman Chemical in Kingsport, OLIN Corporation along the Tennessee River), Oak Ridge National Laboratory's industrial corridor, and the Clinch River-Tennessee River basin's complex industrial PFAS sources contribute to the Knox County supply background.
Geology & Source: Farragut in Knox County is served by the Knoxville Utilities Board (KUB) drawing from Fort Loudoun Lake or Melton Hill Lake (Tennessee River reservoir system) — the Tennessee River watershed drains the Valley and Ridge Province (Ordovician Knox Dolomite, Cambrian Knox carbonate sequence) of the Tennessee Valley — Knox Dolomite and Ordovician carbonate drainage produces moderately hard water at 157 mg/L with TDS 319 mg/L in this west Knox County suburb.
