Abstract:
Vertical migration of a plume of subsurface contamination in the vadose zone to the groundwater is prevented by forming and maintaining one or more desiccation layers in the vadose zone in or above a layer of contamination. Horizontal barrier layers are produced by injecting dry air at a specific elevation in one borehole and removing the air at another borehole. These horizontal layers act as an impermeable barrier to the vertical migration of dissolved contaminants.
