What Makes South Charleston's Water Unique?
Local geology and source profile
South Charleston, West Virginia, in Kanawha County — a Kanawha County city adjacent to Charleston and Dunbar in southwest West Virginia — receives its water from the West Virginia American Water, drawing from the Kanawha River (Kanawha County) through the southwest West Virginia distribution.
The moderately hard 101 mg/L hardness and TDS of 189.3 mg/L reflect the southwest West Virginia Kanawha County supply's moderate calcareous character — the Kanawha River drains the Appalachian Plateau's Pennsylvanian shales and Mississippian Greenbrier Limestone, producing moderate calcareous hardness consistent with the Kanawha Valley communities (compare Teays Valley WV: 125 mg/L on a harder limestone draw). The Kanawha River at Kanawha County — Mississippian Greenbrier Limestone (calcareous — primary hardness contributor), Pennsylvanian Kanawha Formation (slightly calcareous — secondary contributor), and Devonian Chemung Group (insoluble — dilutant from upper watershed).
At 101 mg/L, South Charleston's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 5.6 ppt warrants a certified drinking water filter — the Kanawha County southwest West Virginia chemical corridor (DuPont-Chemours legacy PFAS from Institute and South Charleston plants) contribute to South Charleston's readings.
Geology & Source: South Charleston in Kanawha County draws from the West Virginia American Water on the Kanawha River (Kanawha County, southwest West Virginia) — the Kanawha River drains the Appalachian Plateau (Mississippian Greenbrier Limestone — calcareous) and Pennsylvanian Kanawha Formation (slightly calcareous) — West Virginia Kanawha County Kanawha River Pennsylvanian-Mississippian calcareous supply produces moderately hard water at 101 mg/L with TDS 189.3 mg/L.
