<p>Method for active in situ multi-element gas sparging for bioremediation for removal of contaminants in a soil formation containing a subsurface groundwater aquifer or a substantially wet unsaturated zone, the multi-gas contained in bubbles, wherein the introducing of an oxidizing agent comprising ozone mixed with ambient air to provide an encapsulated multi-element gas in micro-fine bubbles sized by microporous diffusers and bubble chamber in combination with controlling bubbles size, without applying a vaccum for extraction of stripped products or biodegration by-products wherein diffusers form micro-fine bubbles containing multi-element gas that oxidizes, by stripping and decomposition, chlorinated hydrocarbons from the aquifer and surrounding saturated soil formation into harmless by-products; effective to increase the efficiency and speed of remediation of a site.</p> |
