Abstract

Method and apparatus for groundwater remediation with microporous diffusor removal of contamination, including dissolved chlorinated hydrocarbons and dissolved hydrocarbon petroleum products, including the use in injection wells of microfine bubble generators, matched to substrates of selected aquifer regions, for injection and distribution of said bubbles, containing oxidizing gas, through said aquifer and to selectively encapsulating gases including oxygen and ozone in duo-gas bubbles which, in the presence of co-reactant substrate material acting as a catalyst, are effective to encourage biodegradation of leachate plumes which contain biodegradable organics, or Criegee decomposition of leachate plumes containing dissolved chlorinated hydrocarbons, where substrate material acts as a co-reactant with the gas, for decomposing VOCs in a gas/gas/water reaction. Said apparatus includes a plurality of injection wells expending to a depth of a selected aquifer, introducing an oxidizing agent comprising ozone mixed with ambient air to provide a multi-element gas by means of microporous diffusers, without applying a vacuum for extraction of stripped products or biodegradation by-products, wherein said diffusers form micro-fine bubbles containing said multi-element gas that oxidizes, by stripping and de-composition, chlorinated hydrocarbons from the aquifer and surrounding saturated soil formation into harmless by-products; also including a pump for agitating water in the well and injecting microbubbles into the aquifer, effective to alter the path of micro-fine bubbles through a porous solid formation whereby enhanced contact between the oxidizing agent contained in each said bubble by stripping pollutant from solution in ambient water into the mini-atmosphere of each bubble effective to increase the efficiency and speed of remediation of a site.
