Title: METHOD FOR SUBSURFACE SOIL PURIFICATION
Abstract:
A method for subsurface soil purification, having a first step for injecting, into an injection well disposed in a ground area, a purification solution that is heated to a temperature higher than the groundwater temperature and that desorbs pollutants in the subsurface soil from the subsurface soil, and a second step for pumping, from a pumping well disposed in the ground area at a distance from the injection well, groundwater containing the purification solution in which pollutants desorbed from the subsurface soil are dissolved.
