What Makes Red Hill's Water Unique?
Local geology and source profile
Red Hill, South Carolina, in Horry County — a Horry County community adjacent to Conway and Myrtle Beach in northeast South Carolina — receives its water from the Horry County Water Authority, drawing from the Intracoastal Waterway or Lumber River watershed (Horry County) through the northeast South Carolina coast distribution.
The soft 64.5 mg/L hardness and TDS of 101.9 mg/L reflect the northeast South Carolina Horry County Coastal Plain supply's soft character — the Atlantic Coastal Plain's insoluble Cretaceous black formations and Quaternary terrace sands produce soft, low-TDS water consistent with the South Carolina Coastal Plain communities (compare Beaufort SC: 102 mg/L on the deeper calcareous draw; Red Hill softer from the shallower Cretaceous-Quaternary draw). The Horry County supply — Cretaceous Black Creek Formation (insoluble — primary dilutant), Quaternary Coastal Plain terrace sands (insoluble — secondary dilutant), and shallow Eocene calcareous deposits (slightly calcareous — trace hardness contributor).
At 64.5 mg/L, Red Hill's water is soft — scale forms very slowly in appliances, dishwashers remain efficient, and no softening is needed. Annual descaling is appropriate. The PFAS level of 3.5 ppt warrants a certified drinking water filter — the Horry County northeast South Carolina Myrtle Beach metro industrial corridor contribute to Red Hill's readings.
Geology & Source: Red Hill in Horry County draws from the Horry County Water Authority on the Intracoastal Waterway or Lumber River watershed (Horry County, northeast South Carolina coast) — the Coastal Plain at Horry County drains Cretaceous Black Creek Formation (insoluble) over Quaternary Coastal Plain terrace sands (insoluble) — South Carolina Horry County Coastal Plain Cretaceous-Quaternary slightly calcareous supply produces soft water at 64.5 mg/L with TDS 101.9 mg/L.
