What Makes Mooresville's Water Unique?
Local geology and source profile
Mooresville, North Carolina, the Iredell County seat — a major north Charlotte suburban community on Lake Norman (Lake Norman — the largest man-made lake in North Carolina, created by Duke Energy's Cowans Ford Dam on the Catawba River — is a major recreational lake and waterfront community hub; Mooresville has become a premier Lake Norman lakefront community), known as 'Race City USA' (Mooresville has one of the highest concentrations of NASCAR team shops and racing-related businesses in the world — virtually every major NASCAR Cup Series team has a shop within a few miles of Mooresville), a rapidly growing NASCAR and motorsports industry community, and a diverse Iredell County community — draws its municipal water supply from Lake Norman via the Town of Mooresville Water Division. Water hardness in Mooresville measures 119.5 mg/L — classified as moderately hard.
Mooresville's moderate hardness reflects the Catawba River–Lake Norman watershed's calcareous-moderate North Carolina Piedmont crystalline geology. The Catawba River watershed at Mooresville–Iredell County draws from: the Carolina Inner Piedmont Belt (Precambrian–Paleozoic calcareous-moderate Henderson Gneiss — the calcareous-moderate Iredell County crystalline belt); the Carolina Slate Belt (calcareous-moderate metavolcanic terrain). Mooresville Water treatment produces the moderate 119.5 mg/L.
At 119.5 mg/L, Mooresville residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended. Town of Mooresville Water Division consistently delivers water meeting all North Carolina DEQ and EPA Safe Drinking Water Act requirements.
Geology & Source: Lake supply from Lake Norman (Catawba River impoundment) via the Town of Mooresville Water Division — the Iredell County north Charlotte suburban Catawba River corridor (Precambrian–Paleozoic calcareous-moderate Carolina Inner Piedmont gneiss and the Catawba River watershed crystalline belt — the Iredell County Piedmont supply); moderately hard supply at 119.5 mg/L in Iredell County.
