What Makes Huntersville's Water Unique?
Local geology and source profile
Huntersville, North Carolina, in Mecklenburg County on Lake Norman north of Charlotte — one of the fastest-growing towns in North Carolina, a major Charlotte north suburban community with Birkdale Village, the NASCAR team facilities corridor, and significant commercial and residential development along I-77 — draws its municipal water supply from Lake Norman (Catawba River) via Charlotte Water, distributed to Huntersville by the Town of Huntersville Water and Sewer Division. Water hardness in Huntersville measures 119 mg/L — classified as moderately hard.
Huntersville's moderate hardness reflects the Catawba River–Lake Norman watershed's North Carolina Piedmont geology. Lake Norman — the largest man-made lake in North Carolina (Duke Energy Lake Norman, created 1963) — drains the North Carolina Piedmont (Carolina Slate Belt Neoproterozoic metavolcanic and metasedimentary arc terrain — some calcareous marble horizons in the Charlotte Terrane) and the Charlotte Terrane (Kings Mountain Belt — calcareous schist and marble lenses of the Charlotte Terrane Proterozoic basement). Charlotte Water's effective treatment produces the moderate 119 mg/L, which Huntersville's newer distribution infrastructure (developed primarily since the 1990s) maintains without significant accumulation.
At 119 mg/L, Huntersville residents encounter moderate scale accumulation. Faucet aerators and showerheads develop deposits after several months — monthly cleaning with citric acid solution is practical maintenance. Charlotte Water and Town of Huntersville Water and Sewer Division consistently deliver water meeting all North Carolina DHHS and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Catawba River (Lake Norman) via the City of Charlotte Water and the Town of Huntersville Water and Sewer Division — the Mecklenburg County Lake Norman Catawba River corridor (Carolina Slate Belt Neoproterozoic metavolcanic and Piedmont crystalline terrain); moderately hard supply at 119 mg/L in Mecklenburg County.
