Abstract
A method for solidifying an oil-contaminated aqueous waste in situ or ex situ includes the step of combining the oil-contaminated waste with a clay, a cement and a sulfite salt solidification agent to form a solidified waste matrix, wherein the solidification agent undergoes hydration and cementation reactions in the waste matrix in the presence of water. Optionally, heavy metal stabilizing agents can also be combined with the waste.
