Method and Compositions for Treatment of Subsurface Contaminants

Technology Marketing SummaryThis invention describes compositions and methods for oxidizing subsurface contaminants. Compositions include compatible combinations of surfactants, cosolvents and chemical oxidants.
DescriptionCompositions 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 (DNAPLs).Benefits

• Water purification
• Clean up of industrial spills
• Pre-treatment for water filtration

Applications and Industries

• More effective than pump and treat methods
• Can be used for contaminants both denser and lighter than water
• Is a one-step process
