| 摘 要： | 以含1,2-二氯乙烷等10种有机物污染土壤异位修复后回填为例,采用层次化方法评估将按原厂址健康风险评价确定的修复目标进行达标修复后的土壤回填对回填区地下水下游700 m处饮用水井水质的影响.第一层次预测结果显示8种污染物在回填土层淋溶液中的浓度将超过评价标准,可能对目标水井水质造成污染.考虑回填区非饱和带土壤的吸附截留进行第二层次评价的结果显示,到达回填区地下水水面处浓度依然超过评价标准的污染物降低至6种,不能排除对目标水井的水质影响.进一步考虑地下水混合稀释进行第三层次评估的结果显示,经地下水混合稀释后,超过评价标准的污染物降低至4种.最后,考虑饱和带吸附截留作用进行第四层次评估的结果显示,目标水井中超过评估标准的污染物仅1种.由此可见,随着评估层次的不断深入,虽然所需开展的工作及获取的场地参数增加,但是污染物预测浓度更接近目标预测点的浓度,需调整修复目标的污染物数量逐渐减少,污染防治成本将逐渐降低.
