Provided is a method for treating contaminated soil. The method includes providing contaminated soil in a soil chamber that has at least one wall, and at least one floor, at least one heater coupled to or inside of at least one of the walls and at least one substantially elongated floor heater coupled to or in the floor. At least one of the walls at least partially includes a thermally conductive material configured to transfer heat from at least one of the heaters to an interior of the soil chamber. At least one of the walls at least partially encloses an interior of the soil chamber. At least one of the walls can move between a closed position during heating of the soil chamber, and an open position that allows a soil moving vehicle to access an interior of the soil chamber to provide or remove soil to and from the soil chamber unencumbered by piping located within the soil volume. The method also includes heating the contaminated soil within the soil chamber to substantially reduce the level of contaminants in the contaminated soil.

The method of claim 1, wherein heat transfers from at least one of the heaters to thermally conductive material attached to the wall of the soil chamber and then to the contaminated soil, and wherein at least 10% of an interior surface of the wall comprises the thermally conductive material. 9. The method of claim 1, further comprising: collecting vapor from the heated contaminated soil; andproviding fluid to the interior of the soil chamber. 10. The method of claim 1, wherein the heat transfers from at least one of the heaters to thermally conductive material attached to the wall, and then to the contaminated soil. 11. The method of claim 1, wherein at least one of the heaters comprises an electrical heater. 12. The method of claim 1, wherein the heat transfers from at least one of the heaters to thermally conductive material attached to the wall and wherein the thermally conductive material comprises a planar metal plate, sheet, or layer. 13. A method for treating contaminated soil comprising: providing contaminated soil to a soil chamber, wherein the soil chamber comprises at least two walls, that enclose an interior portion of the soil chamber, wherein at least one of the two walls comprises: at least two heaters; andone or more heat conducting plates positioned between one or more of the heaters and the interior of the chamber such that one or more of the heaters is in thermal contact with the heat conducting plates; andheating the contaminated soil in the soil chamber to a desired temperature to reduce a level of contaminants in the contaminated soil, wherein a majority of heat provided to the soil chamber originates from the at least two heaters;wherein at least one of the walls is configured to move between a closed position during heating of the soil chamber, and an open position that allows a soil moving vehicle to access an interior of the soil chamber to provide or remove soil to and from the soil chamber. 14.
