Indicators of Ground Water Quality and Yield for a Public Water Supply in Rock Fracture Zones of the Piedmont

摘要

The investigation deals with field and laboratory studies on indicators of ground water quality and well yields from a variety of igneous, metamorphic, and fault rocks situated in the Piedmont of South Carolina. The yields of 206 wells drilled in Greenwood County varied from 0 to 150 gpm, while the median was 17 gpm. The median yield of the wells situated in fracture traces and lineaments was 25 gpm, which was about twice the median yield of 12 gpm of the randomly located wells. The median productivity of the wells situated in the Carolina Slate Belt was 28 gpm, while the median yields of the Charlotte and Kings Mountain belts were 17 gpm and 15 gpm respectively.
