What Makes Lincolnton's Water Unique?
Local geology and source profile
Lincolnton, North Carolina, in Lincoln County — the Lincoln County seat adjacent to Gastonia and Belmont on the South Fork Catawba River in west-central North Carolina — receives its water from the City of Lincolnton Water Department, drawing from Lake Norman and the South Fork Catawba River through the west-central North Carolina distribution.
The hard 164 mg/L hardness and TDS of 427.1 mg/L reflect the Lincoln County Catawba River supply's hard calcareous character — the Precambrian Kings Mountain Belt contains slightly calcareous metamorphic formations, while the Cambrian Chilhowee Group contributes calcareous mineral content from its calcareous quartzite and sandstone in the western Carolina Piedmont (compare Gastonia NC: 161/419 in Gaston County comparable; Belmont NC: 166/435 in Gaston County comparable; Lincolnton consistent hard from the same Lincoln County Catawba River Precambrian supply). The Catawba watershed — Precambrian Kings Mountain Belt (slightly calcareous — primary hardness contributor), Cambrian Chilhowee Group (calcareous — secondary contributor), and Quaternary Catawba River alluvium (calcareous — TDS contributor).
At 164 mg/L with TDS 427, Lincolnton's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 8.7 ppt is elevated — a certified drinking water filter with PFAS removal is recommended. Review the City of Lincolnton's annual water quality report.
Geology & Source: Lincolnton in Lincoln County draws from the Lincolnton Water on the South Fork Catawba River (Lincoln County, west-central North Carolina) — the Catawba watershed drains Precambrian Kings Mountain Belt (slightly calcareous) and Cambrian Chilhowee Group (calcareous) — North Carolina Lincoln County Catawba River Precambrian supply produces hard water at 164 mg/L with TDS 427.1 mg/L.
