Tailing basins impermeabilization with electroosmotic technique

In the mining area of Sardinia, many years after the end of industrial activity, a lot of tailing basins result as abandoned and constitute dangerous sources of contamination for groundwater and soils. Aimed at avoiding the diffusion of contaminants, electroosmotic technique can be used to realise low permeability barriers both at the basin bottom and along its perimeter. The paper describes the experimental activity carried out for evaluating the effectiveness of the electroosmotic technique and its applicability to a specific case of tailing dam remediation.
