Abstract: During the process of evaluating the groundwater environment, abnormal and accident conditions have been set as the prediction condition to predict the effects on groundwater environment by establishing numerical simulated model. Comparison has been made according to the predicted results under the two conditions, including migrating and diffusing map, the concentration change of central points, migrating distance and maximum diffusing scope of the pollutants. The impacts on groundwater environment and sensitive points were examined.The predicted results would provide guidance and reference on the pollution risk control of groundwater.
