Abstract:
1. A method of decontaminating soil and ground water containing organic contaminants and an iron compound, which comprises the steps of: treating such soils and ground water with an effective amount an alkaline aqueous solution which has a pH of at least 7 and contains an alkaline buffering agent, a peroxide and a water-soluble aminopolycarboxylate-chelating agent for a time sufficient to have the water-soluble aminopolycarboxylate-chelating agent chelate the iron of the iron compound present in the soils and ground water; reacting the chelated iron with the peroxide to catalytically convert the peroxide to an oxidizing agent; and then, contacting the organic contaminants in the soil and ground water with the oxidizing agent to oxidize the organic contaminants to environmentally safe, non-toxic compounds.
