Abstract:
Drinking water, including water from public water systems and private well systems, are expected to contain some levels of contaminants. This project focuses on the water quality of the Public Water Systems (PWSs) in North Carolina by examining the Consumer Confidence Report (CCR) that is required by the Safe Drinking Water Act (SDWA). Data was collected from EPA and USGS websites. By using GIS, this study assesses the spatial distribution of radioactive elements and disinfection by-products violations in North Carolina. After calculating the typical radon activities of various rock types, the result indicates that the of radon level are higher in groundwater near granite bedrock. It is therefore recommend to monitoring the water quality of private wells.
