ABSTRACT:
A method for treating a recalcitrant organic contaminant in contaminated soil or waste includes the steps of (1) maintaining indigenous bacteria or microbes in the contaminated soil or waste at a population level below which the indigenous bacteria or microbes are able to interfere with the enzyme while the enzyme acts against the contaminant and (2) exposing the contaminated soil or waste to an enzyme for a time sufficient to decrease the amount of the recalcitrant organic contaminant in the soil or waste. If the soil or waste also includes one or more readily degradable organic chemical, the method can include the additional step of reducing the content of the readily degradable organic chemical in the soil or waste.
