Wade Hampton Water Hardness & Quality Report (2026)

Wade Hampton, South Carolina, in Greenville County — an unincorporated Greenville County suburb north of Greenville, a residential community in the Greenville metro area — receives its municipal water from the Greenville Water System (GWS), which draws from Table Rock Reservoir (on the North Saluda River, Blue Ridge Mountains), the North Saluda Reservoir, and the Poinsett Reservoir system — the Blue Ridge mountain water supply for the greater Greenville metropolitan area.

The moderately hard 149 mg/L hardness and TDS of 394.1 mg/L are moderately higher than Simpsonville (92.5 mg/L, same GWS supply zone), suggesting that Wade Hampton may draw from a portion of the GWS supply with greater groundwater contribution or a different reservoir blend ratio. The Greenville Water System uses multiple Blue Ridge reservoir sources — the Table Rock (North Saluda River) and North Saluda watersheds drain the Blue Ridge Escarpment (Proterozoic gneiss and amphibolite — very soft), but the Poinsett Reservoir and the Piedmont portions of the system may add moderately harder water. The higher hardness at Wade Hampton likely reflects a greater proportion of local Piedmont or inner Blue Ridge calcium-bearing metamorphic drainage in this distribution zone.

At 149 mg/L, Wade Hampton's 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 8.3 ppt warrants a certified drinking water filter — the Greenville-Spartanburg International Airport, the Michelin North America Greenville Technical Center, and the Greenville County industrial manufacturing corridor all contribute to the elevated PFAS background in this GWS supply zone.
