Abstract
A method of treating a selected volume of soil comprising the steps of providing a pipe network including at least one layer of perforated fluid conduits, inserting the layer of perforated fluid conduits below the selected volume of soil, introducing a selected soil treatment fluid in the selected volume of soil via the perforated fluid conduits, and successively raising and lowering fluid level through the selected volume of soil, thereby ensuring higher extraction and removal efficiencies.
