What Makes Concord's Water Unique?
Local geology and source profile
Concord, North Carolina — the Cabarrus County seat adjacent to Charlotte, famous for Charlotte Motor Speedway — draws its municipal water supply through the City of Concord Utilities, sourcing from Coddle Creek Reservoir (Coddle Creek, a Rocky River tributary in Cabarrus County) and from Rocky River watershed impoundments in the Charlotte–Cabarrus County area, treated at the Cabarrus County Water Resources facilities. Concord and Cabarrus County are part of the greater Charlotte regional water supply system. Water hardness measures 98.5 mg/L — classified as moderately soft.
Concord's moderately soft supply reflects the North Carolina inner Piedmont geology of the Coddle Creek and Rocky River watersheds. The drainage basin lies within the Carolina Terrane — a Precambrian to Ordovician exotic volcanic arc terrane — underlain by metagranite, metavolcanite, and phyllite of the Charlotte Belt metamorphic zone. These Carolina Terrane crystalline rocks — the ancient volcanic arc basement of the Appalachian Piedmont — are essentially free of soluble carbonate, producing naturally soft watershed drainage throughout the Charlotte–Cabarrus County area. The Rocky River system maintains moderately soft supply consistent with the Charlotte Inner Piedmont crystalline geology.
With hardness at 98.5 mg/L, Concord residents experience light to moderate scale accumulation. Faucet aerators and showerheads develop deposits slowly — bi-monthly cleaning with citric acid solution is sufficient. Dishwashers produce clean glassware. City of Concord Utilities and Cabarrus County Water Resources consistently deliver water meeting all North Carolina DEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Rocky River (Yadkin–PeeDee watershed) and Coddle Creek Reservoir via the City of Concord Utilities — the Charlotte Belt Precambrian Carolina Terrane metagranite, metavolcanite, and Inner Piedmont Charlotte–Cabarrus zone; the North Carolina inner Piedmont crystalline terrain produces moderately soft supply at 98.5 mg/L in Cabarrus County.
