Abstract: A method of decontaminating soil and ground water containing organic contaminants and metal compounds. It comprises the steps of first treating such soils and ground water with an effective amount an aqueous solution containing a peroxide and a water soluble chelating agent for a time sufficient to have the water soluble chelating agent chelate at least one of the metals of the metal compounds present in the soil and ground water.
