The transient movement of contaminant under pumpage and recharge conditions in steady ground‐water flow in a vertical cross section of a confined aquifer is simulated using a finite‐element numerical model based on Galerkin technique. Various factors like time step, space increment, and boundary condition affecting the accuracy of the numerical solution are considered in validating results of the numerical model with results of an analytical solution. The solution with the application problem illustrates the effectiveness of subsequent operation of pumpage on the movement of contaminant downstream of the point of injection.
