These walls are installed in situ in the path of the migrating contaminated groundwater by excavating the aquifer material and replacing it with a suitable reactive mixture. Contaminants are removed from the groundwater as a result of chemical reduction, and the subsequent precipitation of sparingly soluble compounds"--Abstract.
