The method essentially creates a lake, if one does not already exist, and uses this lake as a "moving" treating pond for soils contaminated with toxic radicals or compounds containing higher valence state metals. Reducing agent compositions such as saccharides, disaccharides, polysaccharides, FeS. sub. 4, Na. sub. 2 SO3, NaSO. sub. 2, Na. sub. 2 S, and Na. sub. 2 S. sub. 2 O. sub. 5 are introduced into the lake. Contaminated soil from one side of the lake is dragged into the lake, the water of which contains the reducing agent compositions, then is tilled at the bottom of the lake to fully expose the soil to the reducing agent composition, and then is raked upwardly along an opposite side of the lake to form a shoreline of cleaned soil material. Contaminant-consuming micro-organisms and plant life may also be introduced into the lake. The earthmoving process is repeated until lake has passed through and treated all of the contaminated soil site.

The method essentially creates a lake, if one does not already exist, and uses this lake as a "moving" biological treating pond for contaminated soil sites. Contaminated soil from one side of the lake is dragged into the lake, the water of which is infested with contaminant-consuming micro-organisms, then is tilled at the bottom of the lake to fully expose the soil to biological treatment, and then is raked upwardly along an opposite side of the lake to form a shoreline of cleaned soil material. The earthmoving process is repeated until the lake has passed through the treated all of the contaminated soil site. The method performs all decontamination on-site and avoids the requirement for any backfilling of the side after decontamination of the site.

An equal diameter cam is mounted on the output shaft of an internal combustion engine or drive shaft of a piston-type compressor. A piston is joined by a connecting rod to a frame carrying two equal diameter follower rollers engaging the surface of a cam and located at diametrically-opposite points on a line through the center of rotation of the cam. A control arm can be used to control the position of a follower roller. The rotational axis of each follower roller is spaced by the cam surface from the rotational axis of the drive output shaft to transmit torque by converting reciprocating motion impressed by the follower rollers on the cam surface according to the equation: R=r+1/2S sin (. theta. )+1/2S' sin 3 (. theta. +a)+1/2S" sin 5 (. theta.
