Analytical and numerical three-dimensional (3-D) simulations have been conducted and compared to data obtained from a large-scale (50 m), natural gradient field injection experiment. Eighteen different xenobiotic compounds (i.e. benzene, toluene, o-xylene, naphthalene, 1,1,1-TCA, PCE, and TCE) and bromide as a conservative tracer, were for 195 days injected in the anaerobic part of the leachate plume downgradient of the Grindsted Landfill, Denmark. The injection area is an unconfined sandy aquifer with heterogeneities of clay and silt layers. Simulations with homogeneous and heterogeneous hydraulic conductivity compared well to the observed breakthrough curves and snapshots of the injection plumes.
