What Makes Soddy-Daisy's Water Unique?
Local geology and source profile
Soddy-Daisy, Tennessee, in Hamilton County — a Hamilton County city adjacent to Chattanooga and Hixson on the Tennessee River in southeast Tennessee — receives its water from Tennessee American Water, drawing from the Tennessee River (Hamilton County) through the Chattanooga metro distribution.
The hard 202 mg/L hardness and TDS of 485.7 mg/L reflect the southeast Tennessee Hamilton County Tennessee River supply's hard dolomitic character — the Tennessee River's long transit through the Valley and Ridge's Ordovician Knox Dolomite and Mississippian Newman Limestone produces hard, dolomitic water, consistent with the Chattanooga metro communities on the same Tennessee River supply. The Tennessee River at Hamilton County — Ordovician Knox Dolomite (dolomitic — primary hardness contributor), Mississippian Newman Limestone (highly calcareous — secondary contributor), and Quaternary Tennessee River alluvium (calcareous — TDS contributor).
At 202 mg/L with TDS 486, Soddy-Daisy's water is hard. A water softener is recommended to prevent scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 6.7 ppt warrants a certified drinking water filter — the Hamilton County Chattanooga industrial corridor contribute to Soddy-Daisy's elevated readings.
Geology & Source: Soddy-Daisy in Hamilton County draws from the Tennessee American Water on the Tennessee River (Hamilton County, southeast Tennessee) — the Tennessee River at Hamilton County drains the Valley and Ridge (Ordovician Knox Dolomite — dolomitic) and Mississippian Newman Limestone (highly calcareous) — Tennessee Hamilton County Tennessee River Ordovician-Mississippian dolomitic calcareous supply produces hard water at 202 mg/L with TDS 485.7 mg/L.
