What Makes Parker's Water Unique?
Local geology and source profile
Parker, South Carolina, in Greenville County — a Greenville County unincorporated community adjacent to Greenville and Mauldin in the Greenville-Spartanburg metro area — receives its water from Greenville Water, drawing from Table Rock Reservoir and Lake Keowee through the northwest South Carolina distribution.
The soft 83.5 mg/L hardness and TDS of 154.1 mg/L reflect the Greenville County Table Rock supply's soft Appalachian character — the Precambrian Blue Ridge Gneiss is highly insoluble while Cambrian Ocoee Formation metasandstone contributes negligible dissolved minerals from the northwestern South Carolina Blue Ridge Mountains (compare Greenville SC: 81/148 in Greenville County comparable; Mauldin SC: 85/158 in Greenville County comparable; Parker consistent soft from the same Greenville County Table Rock Reservoir Precambrian insoluble supply). The Saluda watershed — Precambrian Blue Ridge Gneiss (insoluble — primary dilutant), Cambrian Ocoee Formation (slightly insoluble — secondary dilutant), and Quaternary Piedmont alluvium (slightly calcareous — minor TDS).
At 83.5 mg/L with TDS 154, Parker's water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 4.7 ppt is moderate — a certified drinking water filter provides added protection. Review Greenville Water's annual water quality report.
Geology & Source: Parker in Greenville County draws from the Greenville Water on Table Rock Reservoir (Greenville County, northwest South Carolina) — the Saluda watershed drains Precambrian Blue Ridge Gneiss (insoluble) and Cambrian Ocoee Formation (slightly insoluble) — South Carolina Greenville County Table Rock Reservoir Precambrian insoluble supply produces soft water at 83.5 mg/L with TDS 154.1 mg/L.
