For environmental application, documentation that current biodegradation rates are sufficient to control or degrade a contaminant plume or zone without creation of unacceptable risk to human health or the environment must be demonstrated. Monitored Natural Attenuation - Encompasses intrinsic bioremediation. Phytoremediation - The general use of plants to remediate environmental media in situ. May or may not involve periodic harvesting of plants, depending upon method utilized. Most effective where ground-water is within ten feet of the ground surface, and soil contamination is within three feet of the ground surface.
Contaminants migrate toward respective electrodes depending upon their charge.
Process may be enhanced through use of surfactants or reagents to increase contaminant removal rates at the electrodes. Process separates and extracts heavy metals, radionuclides, and organic contaminants from saturated or unsaturated soils, sludges, and sediments.
