What Makes Seymour's Water Unique?
Local geology and source profile
Seymour, Tennessee, in Sevier County — a Sevier County community adjacent to Sevierville and Knoxville near the Great Smoky Mountains in east Tennessee — receives its water from the Sevier County Utility District, drawing from the French Broad River through the east Tennessee distribution.
The very hard 229.5 mg/L hardness and high TDS of 599.2 mg/L reflect the Sevier County French Broad supply's very hard dolomitic character — the Ordovician Knox Dolomite is a highly dolomitic formation in the east Tennessee Valley and Ridge province, while the Cambrian Conasauga Formation contributes calcareous mineral content from its calcareous shale and limestone sequence (compare Sevierville TN: 225/589 in Sevier County comparable; Knoxville TN: 233/609 in Knox County comparable; Seymour consistent very hard from the same Sevier County French Broad Ordovician dolomitic supply). The French Broad watershed — Ordovician Knox Dolomite (highly dolomitic — primary hardness contributor), Cambrian Conasauga Formation (calcareous — secondary contributor), and Quaternary French Broad alluvium (calcareous — TDS contributor).
At 229.5 mg/L with TDS 599, Seymour's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 7.6 ppt warrants a certified drinking water filter. Review Sevier County Utility District's annual water quality report.
