Chlorinated Solvents: Future of Bioremediation

One future bioremediation method for chlorinated solvents is that a reactive biowall will be created across the path of contaminated groundwater. The biowall will contain a mixture of locally derived, shredded and partially composted plant material or bark mulch, with coarse sand. The treatment method relies on the flow of the groundwater under a natural hydraulic gradiant through the biowall to promote contact with soluble organic matter. Microbial degradiation of organic carbon within the biowall prdouces reducing conditions that support anaerobic degradiation processes, primarily anaerobic reductive dechlorination in CAHs in groundwater.
