Research on GIS-Based Risk Assessment Method of Groundwater Pollution and its Application

Abstract:

The risk assessment model and parameter system of groundwater pollution were established in this paper. The multi-index evaluation method of groundwater pollution sources was proposed, and the GIS-based risk assessment method of groundwater pollution was produced in comprehensive consideration of groundwater vulnerability and groundwater pollution sources. The multi-index method suggested in this paper was used in the risk assessment of groundwater pollution at a plain area of a big city in North China, and the different grades of groundwater pollution risk were computed. The evaluation results show that the groundwater pollution risk is determined by the combined action of ground pollution sources and groundwater vulnerability. The established risk assessment method of groundwater pollution could give a scientific support for the regional groundwater pollution prevention and control planning.
