Risk Assessments of Groundwater Pollution in Huanshui River Basin

Risk qualitative assessments of groundwater pollution were proposed based on investigation of the pollution sources and hazards rating. GIS was adopted to create the regionalism diagram of groundwater vulnerability, groundwater value and pollution disaster, and then groundwater pollution risk was evaluated. The results showed that high risk region of groundwater pollution mainly distributes over both sides across the river and the city zone, where are of high pollution load, poor ability of self-defend, low capability of antipollution, and easily polluted.
