is the backfill that was used to fill the waste sites at Hanford. The overburden is excavated and sampled to determine if it is contaminated. Clean overburden soil is used again as backfill. Contaminated overburden soil is disposed at the Environmental Restoration Disposal Facility. The Remedial Design Report/Remedial Action Work Plan defines the shallow zone as 15 feet below the surface. MTCA sets the sampling location for soil cleanup at 15 feet below the surface.

Overburden is the term used in mining to describe material that lies above the area of economic interest, i.e., the rock and soil that lies above the coal seam. Also known as 'waste'. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore.
