TPH disappearance from oil-contaminated soil as a function of amendment type; (a) molasses vs. control; (b) compost vs. control; (c) papermill sludge vs. control; and (d) activated carbon vs. control. M: molasses; C: plant compost; PM: papermill sludge; AC: activated carbon; and CON: control. All TPH data for the amended soils were significantly different ( < 0.05) from the control treatment at all sampling dates.
