Exploration of Preferential Transport Paths Using Geoelectrical Salt Tracer Tests

A detailed knowledge of the preferential transport paths is very important for the characterisation of contaminated sites as well as for the planning of site remediation. For instance, the knowledge of the spatial extension of these paths is a prerequisite for a reliable evaluation of the natural attenuation behaviour. In the case of the installation of funnel & gate system for the remediation of the groundwater the knowledge of the preferential transport can significantly contribute to an optimisation of the system and in this way to a minimisation of the cost.
