Water Treatment inHorry County, SC

Horry County water along the Grand Strand is GSWSA water. The Bull Creek Water Treatment Plant pulls raw water from the Atlantic Intracoastal Waterway and blends with Black Creek aquifer groundwater before disinfection. Bull Creek raw water has historically tested high for naturally occurring organic carbon, which is what drives the disinfection-byproduct focus on every annual report GSWSA files. Outside the GSWSA footprint, rural Horry County properties along Highway 905 and Highway 701 still draw private wells from the Black Creek aquifer.
