Electro-kinetic Fences against Sea Water Intrusion

One of the major concerns today in fresh water supply along coastal areas is seawater intrusion into fresh water aquifers mainly as a result of over pumping or salt-water intrusion from the sea. There are several more or less effective methods to overcome this problem, such as recharge basins, or barrier wells to pump out salt water and recharge a fresh water gradient towards the sea. Rising cost of water and maintenance and uncertainty of long-term potable water availability force authorities to find other ways to deal with this problem. An innovative solution is the creation of electro-kinetic barriers along the coast.
