[Groundwater pollution risk mapping method].
Based on methods for groundwater vulnerability assessment not involving in contamination source elements, and lack of the systemic and effective techniques and parameter system on groundwater pollution risk mapping in present, through analyzing the structure of groundwater system and characteristics of contaminant sources, and coupling groundwater intrinsic vulnerability with contaminant sources, the integrated multi-index models were developed to evaluate the risk sources of groundwater contaminant and form the groundwater pollution risk mapping in this paper. The models had been used to a large-scale karst groundwater source of northern China as a case study. The results indicated that vulnerability assessment overlaid risk pollution sources of groundwater could effectively confirm the high risk regions of groundwater pollution, and the methods might provide necessary support for the supervision of groundwater pollution.
