【摘要】 论述污染场地调查之前开展场地水文地质调查的重要性。通过案例说明,水文地质调查能够查明场地内各土层的渗透性,判断相对隔水层和透水层的分布特征,这些信息为建立场地水文地质模型、设计污染土壤取样范围和深度、确定地下水监测井设置深度和滤网位置提供科学依据,从而有效节约调查经费,提高调查结果的准确性。更多还原

【Abstract】 It was demonstrated through a case study that hydrogeology investigation could help to confirm the permeability of different strata of soils,so as to determine the distribution of the water-resisting stratum and the permeable stratum. These data would provide important scientific basis for the hydrogeological model,which will support the soil sampling scope and groundwater monitoring well design,such as the wells depth of groundwater monitoring and filter screen location. Therefore,site investigation incorporating the elements of hydrogeology could reduce the total cost significantly.更多还原
