Description:

This SBIR project focuses on a new device for in-situ soil remediation. The proposed device uses an electromagnetic force to centralize the soil contaminants into a single layer. This is similar to an existing process called the "LasagnaTM" process. The "LasagnaTM" process allows users to treat contaminants completely in-situ, without using injection or extraction wells. Furthermore, the process can be used on a wide range of contaminants, including trichlorethylene (TCE), cadmium, mercury, lead, and nitrates.

The proposed device has several advantages over the current "LasagnaTM" process. First, it is easier to implement. The current "LasagnaTM" process requires burying an electrode under the ground. The proposed device uses a particular arrangement of metal stakes to create the electromagnetic force. Second, the proposed device has a larger exposure region than the current "LasagnaTM" process, which can only penetrate to the depth of the buried electrode. Third, the proposed device will be less expensive to build. It is constructed out of commercially available materials. Finally, the proposed device will exert a greater force on the soil contaminants for a given amount of supplied power. In Phase I, a prototype device will be developed and tested. The field patterns generated by this device will be increased and then the performance of the device in an actual soil sample will be measured.
