The groundwater flow and solute transport characteristics of fissured Lower Cretaceous argillites have been investigated at the abandoned Muenchehagen hazardous waste disposal site. The investigations were essentially focussed on the properties and processes that characterize the rocks as a natural migration barrier with special regard to organic contaminants. Basing on a comprehensive field study particularly multitracer experiments and supplementary laboratory diffusion and batch sorption experiments are presented. An one-dimensional semi-analytical transport model (POLLUTE) has been used for the interpretation of field tracer tests and for the evaluation of the impact of matrix diffusion on solute transport at different observation scales. The intense fracturing resulted in a relatively high permeability of the argillites. Solute transport and attenuation in this hydrogeological setting is mainly governed by matrix diffusion and sorption. Dissolved reactive species, such as organic solvents, are most effectively retarded.
