Abstract: Apparatus for in-situ remediation of contaminant-bearing earthen material includes a generally cylindrical tined assembly; a housing for mounting the tined assembly for rotational motion; an hydraulic driver for delivering torque to rotate the tined assembly; and an additive supply system configured to drop an additive into the space defined by and along the length of the cylindrical tined assembly.

Abstract: A shopping cart (12) comprising a frame assembly (28) having a pair of longitudinal frame rails (132, 134) extending between a pair of transverse frame rails (136, 138), a pair of upwardly extending axle tabs (63) for receiving an axle (156) onto which a pair of front wheel assemblies (30) are rotatably attached such that the axis of rotation of the front wheel assemblies (30) is above transverse frame rail (138) and a pair of rear wheel assemblies (30) which are rotatably mounted on fully rotatable casters (152, 154) such that the axis of rotation of the rear wheel assemblies (30) is below the transverse frame rail (136) and above the transverse frame rail (138).
