Electrokinetic Remediation - Advantages



The in-situ method is preferred since it would be less expensive. The process can target a specific area since the remediation will take place only between the electrodes. The fact that the soil need not be removed indicates that the amount of energy needed for this process would be comparatively lower than ex-situ procedures.

The technique is applicable for a wide range of contaminants since metal contaminants can be moved because they have charge and the non-charged contaminants are moved due to induced flow.  It is flexible to be used as both in-situ and ex-situ method (Sharma and Reddy., 2004) and it can be tailored to site specific conditions.
