First Claim
Patent Images
1. A method of oxidizing a subsurface non-aqueous phase liquid (NAPL) contaminant comprising:
- providing an effective amount of a solution comprising at least one sulfonated surfactant and at least one permanganate chemical oxidant; and
introducing the solution to the subsurface NAPL contaminant to solubilize and oxidize the subsurface contaminant.

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.
