  • Method and Compositions for Treatment of Subsurface Contaminants
    Publication number: 20100003082
    Abstract: Compositions and methods are provided for oxidizing subsurface contaminants. Compositions include compatible combinations of surfactants, cosolvents and chemical oxidants. Compositions have been identified that provide compatible combinations of surfactants and chemical oxidants that maximize oxidant productivity on solubilized contaminants. The compositions and methods are especially effective on the treatment of dense non-aqueous phase liquids or DNAPLs.
