A treatment slurry is emplaced in soil in columns formed by displacement of soil by a direct push rod, a vibrating beam, or otherwise. The treatment slurry is pumped into the impression created as the rod or vibrating beam is withdrawn from the subsurface, creating a vertical column in the subsurface with a cross-sectional shape of the rod or vibrating beam that is filled with the treatment slurry. The vertical columns are spaced at suitable distances to allow for diffusion of a treatment agent in the treatment slurry into the surrounding soils or sediments to treat the target contaminants in the subsurface soils or sediments. |
