What Makes Lexington's Water Unique?
Local geology and source profile
Lexington, North Carolina, in Davidson County — the Davidson County seat in the North Carolina Piedmont Triad, known as the Barbecue Capital of the World, a manufacturing and county seat city between Winston-Salem and Salisbury in the central Piedmont Triad corridor — receives its municipal water from the City of Lexington Water Division, drawing from High Rock Lake (the Yadkin River impoundment in Davidson County) through the Lexington water treatment plant.
The moderately hard 155 mg/L hardness and TDS of 387.7 mg/L reflect the Yadkin River watershed's North Carolina Piedmont geology. The Yadkin River drains the Blue Ridge (crystalline metamorphic and igneous — Ashe Formation, Grandfather Mountain Window) and the Carolina Slate Belt (Cambrian-Ordovician volcanic-sedimentary metamorphic), producing moderately hard water from the limited carbonate content in the Piedmont crystalline terrain. High Rock Lake concentrates some minerals through reservoir chemistry, contributing to the elevated TDS relative to the raw Yadkin.
At 155 mg/L, Lexington'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 8.2 ppt warrants a certified reverse osmosis drinking water filter — the Yadkin River industrial corridor (Alcoa Badin aluminum smelter, historical fluoride-PFAS-class industrial legacy), the Davidson County manufacturing belt, and the North Carolina Piedmont PFAS complex contribute to Lexington's elevated readings.
Geology & Source: Lexington in Davidson County draws from the City of Lexington Water Division on the High Rock Lake (Yadkin River, Davidson County) — the Yadkin drains the North Carolina Piedmont (Precambrian-Cambrian crystalline gneiss and schist) and the Blue Ridge volcanic-metamorphic belt — North Carolina Piedmont crystalline and Blue Ridge watershed drainage produces moderately hard water at 155 mg/L with TDS 388 mg/L in this Davidson County North Carolina city.
