| As the developing of industry and agricultural, the people used the groundwater more and more, which threatened the quality of the groundwater. In some area, the linking of waste landfill and oil tank, and discharging of the waste water without treating had polluted the groundwater. In order to protecting the groundwater, beginning study the groundwater polluting risk was important.The west developed countries at the head of American began to study the groundwater pollution earlier. Now, they had made some fruit, such as the DRASTIC model, GMS, Visual Modflow, which was significance in the risk reach of groundwater. The study in china in this area was later, and the content was scattered.In this study, we referenced the 4 step of environment risk study: Hazard identification, Dose-response evaluation, Exposure evaluation and Risk characterization. Contacting the reality of the research area, our study way was risk screening, model simulating, and risk forecast analysis.The research area located the north of Qiqihar city, which included city and suburb. The research area had the high density populations,much industry activity and agriculture activity. Connection the research state in China and the fact of the research area, we made the... |
