What Makes Belmont's Water Unique?
Local geology and source profile
Belmont, North Carolina, in Gaston County — a Gaston County city adjacent to Gastonia and Mount Holly on the Catawba River in the Piedmont — receives its water from the City of Belmont Water Department, drawing from the Catawba River through the Piedmont North Carolina distribution.
The hard 142.5 mg/L hardness and TDS of 338.5 mg/L reflect the Gaston County supply's hard Piedmont character — the Precambrian Kings Mountain Belt schist provides insoluble dilution, while the Cambrian Pumpkinvine Formation contributes calcareous mineral content from its phyllite and calcareous schist; Belmont's higher hardness relative to upstream Catawba communities reflects the cumulative mineral loading along the Catawba River corridor (compare Gastonia NC: 138/328 in Gaston County comparable; Mount Holly NC: 145/349 in Gaston County comparable; Belmont consistent hard from the same Gaston County Catawba River Precambrian supply). The Catawba watershed — Precambrian Kings Mountain Belt schist (insoluble — primary dilutant), Cambrian Pumpkinvine Formation (slightly calcareous — primary hardness contributor), and Quaternary Catawba River alluvium (calcareous — TDS contributor).
At 142.5 mg/L with TDS 339, Belmont's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 7.6 ppt warrants a certified drinking water filter. Review the City of Belmont's annual water quality report.
Geology & Source: Belmont in Gaston County draws from the Belmont Water on the Catawba River supply (Gaston County, Piedmont North Carolina) — the Catawba watershed at Gaston County draws from Precambrian Kings Mountain Belt schist (insoluble) and Cambrian Pumpkinvine Formation (slightly calcareous) — North Carolina Gaston County Catawba River Precambrian supply produces hard water at 142.5 mg/L with TDS 338.5 mg/L.
