What Makes Indian Trail's Water Unique?

Local geology and source profile

Indian Trail, North Carolina, in Union County — a major south Charlotte suburban community (Indian Trail is one of the fastest-growing municipalities in North Carolina — a major Union County suburban community directly south of the Charlotte city boundary), a primarily residential bedroom community for Charlotte, a diverse Union County community with a significant Latino-American and Indian-American population in the south Charlotte growth corridor, and part of the Charlotte–Concord–Gastonia MSA (the Charlotte metro area is one of the fastest-growing major metros in the US) — draws its municipal water supply from the Catawba River via Charlotte Water (the Charlotte-Mecklenburg Utilities system serving parts of Union County). Water hardness in Indian Trail measures 133 mg/L — classified as moderately hard.

Indian Trail's moderate hardness reflects the Catawba River Charlotte Piedmont watershed's calcareous-moderate crystalline geology and Charlotte Water distribution characteristics. The Catawba River at Indian Trail–Union County draws from the Carolina Slate Belt (calcareous-moderate metavolcanic and meta-sedimentary Paleozoic terrane) and the Mecklenburg–Union County Inner Piedmont (calcareous-moderate gneiss and amphibolite). Charlotte Water distributes through the south Union County Indian Trail zone, producing the moderate 133 mg/L.

At 133 mg/L, Indian Trail residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended. Charlotte Water consistently delivers water meeting all North Carolina DEQ and EPA Safe Drinking Water Act requirements.

Geology & Source: River supply from the Catawba River (Lake Wylie and Mountain Island Lake) via the Charlotte Water — the Union County south Charlotte suburban corridor (Precambrian–Paleozoic calcareous-moderate Carolina Slate Belt and Inner Piedmont gneiss — the south Charlotte Union County Piedmont crystalline; Charlotte Water south distribution zone); moderately hard supply at 133 mg/L in Union County.
