The invention relates to a method for removing a contaminant in situ from soil containing the contaminant, by contacting the soil containing the contaminant with a reagent in situ to remove the contaminant from the soil and form a mixture; removing the mixture from the soil; and removing the contaminant from the mixture, wherein the reagent is not citric acid. The invention further relates to a method for removing a contaminant in situ from soil containing the contaminant, by contacting the soil containing the contaminant with a reagent in situ and mobilizing the contaminant by electroremediation to form a mixture containing the contaminant; and removing the contaminant from the mixture. The invention further relates to a method for removing a contaminant from soil in situ containing the contaminant, by contacting the soil containing the contaminant with a chelate in situ to form a mixture containing a contaminant-chelate complex; removing the mixture from the soil; and contacting the mixture with an ion exchange resin, whereby the contaminant-chelate complex is separated from the mixture. The invention further relates to a method of removing a contaminant in situ from soil containing the contaminant, by contacting the soil containing the contaminant in situ with a chelate to form a first mixture containing a contaminant-chelate complex; removing the first mixture from the soil; chemically destroying the contaminant-chelate complex of the first mixture to produce a second mixture containing the contaminant; and removing the contaminant from the second mixture.
