The purpose of this work is to illustrate the utility of the diffusive tracer-test method for investigating the influence of diffusion-medicated processes on solute transport at the field scale. The diffusive tracer test involves the use of a suite of tracers of various sizes (i.e., diffusivities), and is based on the hypothsis that diffusion-mediated processes will generally be sensitive to the aqueous diffusivity of the solute. Hence, the transport of tracers with different diffusivities should be different when diffusion-mediated processes are important. The method was successfully applied to a field site representative of alluvial aquifer systems.
