为了解榆次西窑水源地的环境易污染程度及石家庄—太原原油管道可能对西窑水源地的地下水产生影响的情况,利用DRASTIC评价法对榆次西窑水源地进行地下水脆弱性评价,并利用GMS软件模拟原油泄漏,研究其对西窑水源地水质的影响。DRASTIC评价结果表明:西窑水源地地下水脆弱性差;假设在距供水井距离最近处管道破损,污染发生0.5 d,其对供水井产生严重影响,且石油类超标>300 d。结合污染情况,提出了具体的原油管道对地下水污染的防治措施。

In order to explore the groundwater vulnerability and the impacts of Shijiazhuang-Taiyuan oil pipeline on Xiyao water source, we evaluated the groundwater vulnerability using DRASTIC method and simulated the impacts of oil spill contamination on the groundwater quality using GMS (groundwater monitoring system). Results suggest that the groundwater vulnerability in Xiyao water source is rated as weak. If oil leakage occurs in the shortest distance to a water supply well, the groundwater quality would be severely affected in half a day, and the oil concentration would be exceeding standard for over 300 days. Some recommendations for pollution prevention and control were offered in consideration of the pollution situation.
