垃圾堆埋对石家庄地下水源的污染及其防治对策

Pollution of the ground-water source of Shijiazhuang City, Hebei, China by garbage dumping and burial and countermeasures for pollution prevention and control

石家庄冲积扇含有优质的地下水,是石家庄市区200多万人和工农业用水的主要供水水源。但其地表堆埋了大量的城市垃圾,对地下水源构成严重的污染威胁。通过卫星遥感图像数据解译、现场取样测试等工作,对该地下水源地的环境水文地质条件和垃圾堆放、填埋、分布状况及其对地下水的污染进行了评价,并针对性地提出了应对措施和对策。

High-quality groundwater contained in the Shijiazhuang alluvial fan is the main source of domestic water supply for more than two million inhabitants in the urban district of Shijiazhuang as well as industrial and agricultural water supplies. However, substantial amounts of urban garbage are dumped and buried at the surface, which constitutes a serious pollution threat to the groundwater source. With the help of the interpretation of satellite remote sensing image data and on-the-spot sampling and tests, the authors have evaluated the environmental-hydrogeological conditions of the ground water source area and garbage dumping, burial and distribution and their pollution of groundwater. In addition, countermeasures for pollution prevention and control are also presented.
