A chemical composition and method for treating oil-contaminated waste waters, and, more particularly, waste waters in the form of oily emulsions that may also contain dissolved metal ions, and/or metal solids, to sorb (adsorb and/or absorb) the contaminants between and within platelets of sodium bentonite clay particles, and calcium bentonite clay particles, and the contaminants are encapsulated or trapped in a matrix of calcium bentonite platelets and sodium bentonite platelets that are flocculated by a flocculant, such as a cationic polymer, so that leaching of contaminants into the waste water, or subsequently into a liquid portion of a landfill, is unexpectedly reduced.
