Scientists in the University of North Carolina Department of Environmental Sciences and Engineering say that groundwater supplies located in granite and gneiss rock types in the Blue Ridge, Inner Piedmont, and Raleigh Belt geologic regions are more likely to have high concentrations of radon-222 than other groundwater supplies in North Carolina. The study was supported by the Water Resources Research Institute and provides recommendations for managing radon concentrations in drinking water.
