A treadmill with a trampoline-like surface that includes an endless belt with generally parallel lateral edges and an upper surface forming a running surface and belt supports in close proximity to and extending along the lateral edges of the endless belt. The treadmill further includes a suspension system for suspending the endless belt from the supports as the belt moves in a longitudinal direction. The suspension system is comprised of a series of connectors along each lateral edge, each connector including at least one roller adapted to engage and move along the support, and a bracket connected between the roller and lateral edge of the endless belt. Each roller has an axis of rotation and the bracket is oriented to maintain the axis of rotation of each roller at an angle of between about 10-25 degrees toward the running surface relative to a plane perpendicular to the running surface.

Heavy metals contaminants in soils are fixed and rendered non-leachable by the process of heating the metal contaminated soil containing a hydrocarbon liquid, at an elevated temperature sufficient to convert at least a part of the liquid hydrocarbon into solid carbon or coke deposited on the surface of the soil and subjecting the thus heated soil to sufficient microwave radiation to sustain at least a partial fusion or melting process that results in a fixing of the heavy metals in the soil.
