What Makes Weddington's Water Unique?
Local geology and source profile
Weddington, North Carolina, in Union County — a Union County town adjacent to Monroe and Matthews in the south Charlotte suburbs — receives its water from Union County Public Works, drawing from the Catawba River through the Piedmont North Carolina distribution.
The moderately hard 109.5 mg/L hardness and TDS of 220.9 mg/L reflect the Union County supply's moderate Piedmont character — the Precambrian Carolina Slate Belt provides insoluble dilution, while the Cambrian Uwharrie Formation contributes slightly calcareous mineral content from its phyllite and calcareous schist in the south North Carolina Piedmont (compare Monroe NC: 106/213 in Union County comparable; Matthews NC: 112/229 in Mecklenburg County comparable; Weddington consistent moderate from the same Union County Catawba River Precambrian supply). The Catawba watershed at Union County — Precambrian Carolina Slate Belt (insoluble — primary dilutant), Cambrian Uwharrie Formation (slightly calcareous — primary hardness contributor), and Quaternary Catawba River alluvium (slightly calcareous — minor TDS).
At 109.5 mg/L with TDS 221, Weddington's water is moderately hard — mild scale buildup. Semi-annual descaling is appropriate. The PFAS level of 5.8 ppt warrants a certified drinking water filter. Review Union County Public Works' annual water quality report.
Geology & Source: Weddington in Union County draws from the Union County Water on the Catawba River supply (Union County, Piedmont North Carolina) — the Catawba watershed at Union County draws from Precambrian Carolina Slate Belt (insoluble) and Cambrian Uwharrie Formation (slightly calcareous) — North Carolina Union County Catawba River Precambrian supply produces moderately hard water at 109.5 mg/L with TDS 220.9 mg/L.
