The heterogeneity of porous media increases the uncertainty in the pollution extent estimation for groundwater solute transport. To assess the impact of porous media heterogeneity on the groundwater transport, this study applied random field theory for the simulation of hydraulic conductivity and groundwater flow and developed the random walk approach to approximate the solute transport in groundwater. A spectral-based conditional random field simulation approach was applied to perform the uncertainty analysis of transport charateristics with consideration of filed hydraulic conductivity observations. Our development was verified by comparing the analytical solutions in published papers, and also validated by comparing the field concetration observations at Cape Cod in the US.
