ELECTROKINETIC ION TRANSPORT THROUGH UNSATURATED SOIL : 2. APPLICATION TO A HETEROGENEOUS FIELD SITE

Presentation of a site characterization, experimental equipment for extraction of chromate by electrokinetic transport of acetate. Schematic of the water circulation system and pH control system for ceramic fielf electrodes. Representation of cross-section of soil properties, apparent electrical conductivity, volumetric moisture content and acetate concentrations. Numerical method with 3D view of the model domain is discussed with numerical results. Predicted concentrations after 837 hours of electrokinetic transport. Discussion of the velocity in layered and homogeneous models.
