What is claimed is: 1. An apparatus for remediating a contaminated area including one or more gases comprising: an injection well; a source of a liquid suitable for promoting biological degradation of organic compounds; a source for delivering a gas including an oxidizing gaseous agent; an aerosolizer for aerosolizing the liquid; a microporous diffuser disposed in the well for generating coated microbubbles of a controlled size comprising the gas in the microbubbles and a liquid coating surrounding the gas. 2. The apparatus of claim 1, wherein the microporous diffuser provides microbubbles having a diameter of less than 200 microns. 3. The apparatus of claim 1, further comprising: a controller for controlling the ratio of gas and liquid in generating the coated microbubble. 4. The apparatus of claim 1, further comprising: a controller for controlling mixing of ambient air with said liquids. 5. The apparatus of claim 1, further comprising: an agitator to pulse or surge the microbubbles into the well to improve transport of coated microbubbles through the contaminated area. 6. The apparatus of claim 5 wherein the agitator comprises a submersible pump. 7. The apparatus of claim 1 wherein the liquid is selected from the group consisting of hydroperoxides, potassium permanganate, and Fenton reaction reagents. 8. The apparatus of claim 4, wherein the controller for controlling mixing comprises: a wellhead controller for equalizing flow between formations of differing permeability. 9. The apparatus of claim 5 wherein the agitator alternates pumping of water and delivery of coated microbubble injection. 10. The apparatus of claim 1 wherein the liquid is hydrogen peroxide, or an intermediate by-product of decomposition of ozone and an organic compound, the intermediate by-product including formic peracid, acetic peracid, hydroxymethylhydroperoxide, or 2-hydroxy-2-propyl hydroperoxide, and the gaseous oxidizing includes ozone in sufficient quantities to decontaminate contaminates in the contaminated area.
