A process for decontaminating a metal contaminated soil aggregate wherein at least one water soluble dialkyldithiocarbamate is admixed with an initial soil slurry so as to obtain a product aqueous soil slurry comprising one or more water insoluble metal-dialkyldithiocarbamate complexes which insoluble complexes may then be physically separated from the soil slurry to leave behind a product having a metal contamination level lower than that of the initial contaminated soil.
