What Makes White House's Water Unique?
Local geology and source profile
White House, Tennessee, in Sumner County — a Sumner County city adjacent to Portland and Hendersonville north of Nashville in north Tennessee — receives its water from the White House Utility District, drawing from Drake Creek reservoir through the north Tennessee distribution.
The soft 95 mg/L hardness and TDS of 148.7 mg/L reflect the Sumner County Drake Creek supply's soft calcareous character — the Mississippian Ste. Genevieve Limestone contributes modest calcareous mineral content, while Ordovician Knox Dolomite contributes additional dissolved minerals from the Tennessee Highland Rim (compare Portland TN: 93/144 in Sumner County comparable; Hendersonville TN: 97/152 in Sumner County comparable; White House consistent soft from the same Sumner County Drake Creek reservoir Mississippian calcareous supply). The Cumberland watershed at Sumner County — Mississippian Ste. Genevieve Limestone (slightly calcareous — primary hardness contributor), Ordovician Knox Dolomite (calcareous — secondary contributor), and Quaternary Drake Creek alluvium (slightly calcareous — minor TDS).
At 95 mg/L with TDS 149, White House's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 3.2 ppt is low — a clean result for north Tennessee. Review the White House Utility District's annual water quality report.
