Abstract
A process for the in situ remediation of soil comprising introducing at least one co-metabolite for treating contaminants in a contaminated soil region into the contaminated soil region wherein the source of the at least one co-metabolite is at least one root zone located within the contaminated soil region, wherein each root zone contains the root system of a plurality of plants capable of releasing the at least one co-metabolite, and transmitting direct electric current through the contaminated soil region between a first electrode and a second electrode having opposite charge, wherein the first electrode is located at a first end of the contaminated soil region and the second electrode is located at the opposite end of the contaminated soil region.
