Abstract
A method for remediating hazardous materials susceptible to nucleophillic attack is disclosed wherein sodium hydroxide is applied to a treatment zone in situ for raising the pH of the treatment zone to at least about 12.5 so that alkaline hydrolysis effectively breaks down the hazardous substance by replacing a leaving group with a nucleophile. The method is well suited for in situ use in the vadose zone to treat contaminated soil and groundwater.
