滹沱河石家庄段地下水污染风险评价

Risk assessments of groundwater pollution in the Shijiazhuang reach of the Hutuo River, China

摘要: 通过对滹沱河石家庄段污水排放的调查，利用实验测试和恢复费用法对研究区内地下水的污染进行风险评价。研究结果表明，河道内的污水已经污染了地下水，20年的时间段内点污染源和线污染源对地下水的污染面积分别为4.86km2、16.41km2，污染体积分别为0.2245×108m3和1.05×108m3。利用恢复费用法, 采用2套方案，计算潜在的经济损失分别为2.08×108元和0.7×108元。

Abstract: The paper tries to use the test method and replacement cost method to assess the risk of groundwater pollution through investigation of sewage discharge in the Shijiazhuang reach of the Hutuo River of. The results show that the groundwater in the study area has been polluted by sewage naturally stored and flowing in the Hutuo River. The area of polluted groundwater by point pollution sources and linear pollution sources in a time interval of 20 years are 4.86 and 16.41 km2 respectively, and the volumes of polluted groundwater are 22.45 million m3 and 105 million m3. With the replacement cost method, two schemes were used to calculate the potential economic losses to be ~208 million yuan and 70 million yuan respectively.
