目前含水层清理的常用方法是提取受污染的地下水，将水中污染物浓度降低到一定水平后，将处理后的水注入含水层，或者在环境和经济可行的情况下，将其排放到地表水体。这种操作的正确设计无论是经济上还是环境上都非常重要。本文开发了一种方法，可以帮助确定最佳抽水井数量、抽水量和位置，从而避免含水层进一步退化。复势理论已用于推导将一个、两个或多个抽水井的捕获区与含水层其余部分分开的流线方程，提出了一系列捕获区类型曲线，可用作含水层清理项目设计的工具。这些类型曲线的使用通过假设的现场案例进行展示。
Currently a common method of aquifer cleanup is to extract the polluted ground water and, after reducing the concentration of contaminants in the water below a certain level, the treated water is either injected back into the aquifer, or if it is environmentally and economically feasible, released to a surface-water body. The proper design of such an operation is very important, both economically and environmentally. In this paper a method is developed which can assist in the determination of the optimum number of pumping wells, their rates of discharge and locations, such that further degradation of the aquifer is avoided. The complex potential theory has been used to derive the equations for the streamlines separating the capture zone of one, two, or more pumping wells from the rest of the aquifer, A series of capture-zone type curves are presented which can be used as tools for the design of aquifer cleanup projects. The use of these type curves is shown by an hypothetical field case example.
