AB: The need to assess quantitatively the safety of waste repositories in deep geological media has aroused the development of efficient models of groundwater flow and contaminant transport in fractured media. Application of stochastic methods to fluid flow and transport in fractured media is relatively new research area. But their studies are limited to the solute transport in stationary velocity field without considering the boundary conditions, and these strict assumptions limit the application of the stochastic theories to solute transport in complicated natural media. Another limitation exists in their studies is that they can just calculated the mean concentration and related spatial moments, but it is very hard to use their methods to get the solution for uncertainties associated with the predicted mean plume, more specifically, the variance of perturbation concentrations. In this study, we develop a nonstationary stochastic theory for contaminant transport in fractured, heterogeneous media. A dual-permea
