What Makes Stallings's Water Unique?
Local geology and source profile
Stallings, North Carolina, in Union County — a Union County town adjacent to Indian Trail and Matthews in the south Charlotte metro of Union County — receives its water from Union County Public Works (or Charlotte Water system), drawing from local Union County reservoir sources through the south Charlotte metro distribution.
The moderately hard 126.5 mg/L hardness and TDS of 278.2 mg/L reflect the south Charlotte metro Carolina Piedmont watershed's moderate calcareous character — consistent with other Charlotte-metro Union County communities (Indian Trail: ~125 mg/L; Monroe: ~130 mg/L). The Union County watershed drains the Carolina Piedmont — Precambrian Kings Mountain Schist (slightly calcareous — primary hardness contributor at south Charlotte Piedmont), Precambrian Charlotte Belt granite (slightly calcareous), and Precambrian Carolina Slate Belt (slightly calcareous phyllite). The slightly calcareous Carolina Piedmont metasedimentary and metamorphic terranes produce the moderately hard south Charlotte supply.
At 126.5 mg/L, Stallings' water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 6.7 ppt warrants a certified drinking water filter — the Union County south Charlotte suburban corridor, the Charlotte metro industrial PFAS background, and Fort Bragg/Fort Liberty (Cumberland County — AFFF, the dominant NC PFAS source with southwest Charlotte watershed influence) contribute to Stallings' readings.
Geology & Source: Stallings in Union County draws from the Union County Public Works on Tuckahoe Creek Reservoir or Charlotte Water imports (Union County, south Charlotte metro) — the watershed drains the Carolina Piedmont (Precambrian Kings Mountain Schist — slightly calcareous) — North Carolina Union County Piedmont slightly calcareous watershed produces moderately hard water at 126.5 mg/L with TDS 278.2 mg/L.
