Abstract
An apparatus for removing a predetermined amount of contaminated overburdened soil. The apparatus comprises a container adapted to move along the soil. It is advanced forward and controlled by a backhoe or other crane configuration. A blade is attached at the front end of the container to cut a predetermined layer of overburdened soil. Vertical plates are included to cut the edge of the soil at the outer ends of the blades and confine the soil within the container. An air control device is also provided for controlling the flow of airborne particulates resulting from the cutting operation.
