A technique is presented for calculating pollutant removal rates during groundwater restoration processes. The hydraulic information required by the method is obtained from the conservative tracer breakthrough curve for a flow system. The influence of adsorption and ion exchange chemistry on species transport is included through, application of the method of characteristics. The combined result gives the effluent concentration at a production well as a function of time during a restoration project. The method is applicable for any well pattern and its economy is such that a pencil and paper calculation will suffice for yielding quantitative answers for complex flow problems. The method is applied to calculate ammonium removal rates for site restoration by recirculation with chemical sweeps following in situ leach mining of uranium.
