The traditional methods described above require the use of heavy machinery, which may be difficult to access in a built-up environment. Since time is of essence in arresting the spread of contaminants to minimize the cleanup cost, novel methods that can overcome these difficulties are needed. The creation of an electrokinetic barrier is one such method that can address these concerns. In this method, an electrical field generated within/outside the contaminated zone causes the formation of a counter-gradient that can control the flow of water and contaminants. The relative ease of implementing electrokinetic barriers has generated a lot of interest in this technique as a viable alternative to traditional methods. The principles governing the creation of electrokinetic barriers are described in the next section.
