A microporous diffuser includes a first elongated member including at least one sidewall having a plurality of microscopic openings. The sidewall defines an interior hollow portion of the member. The diffuser has a second elongated member having a second sidewall having a plurality of microscopic openings, the second member being disposed through the hollow region of the first member. The diffuser includes an end cap to seal a first end of the microporous diffuser and an inlet cap disposed at a second end of microporous diffuser for receiving inlet fittings.

What is claimed is: 1. A method comprises: forming microbubbles including an oxidizing gas entrapped by water and having a coating of hydrogen peroxide over the microbubbles; and introducing the microbubbles into groundwater to treat an aquifer or soil formations. 2. The method claim 1 wherein forming the microbubbles comprises: introducing the oxidizing gas as an air-ozone stream through a first centrally disposed member, having sidewalls of a microporous material that is disposed in a wet soil formation to produce microbubbles of water entrapping air-ozone; and introducing a liquid including hydrogen peroxide through a space between the first centrally disposed member and a second member that surrounds the first centrally disposed member, and which is in fluid communication with the first centrally disposed member, to provide the coating of hydrogen peroxide. 3. The method of claim 2 wherein space between the first and second members is filled with a hydrophilic packing material. 4. The method of claim 2 wherein space between the first and second members is filled with a packing material comprised of glass beads, silica particles or porous plastic, and receives the hydrogen peroxide. 5. The method of claim 1 wherein the microbubbles have a diameter of within a range of about 1-50 microns. 6. The method of claim 1 wherein the microbubbles have a diameter in a range of about 5-20 microns. 7. The method of claim 1 wherein the microporous bubbles are introduced using a microporous diffuser. 8. The method of claim 7 wherein the microporous diffuser includes a nutrient and/or catalyst a gent. 9. The method of claim 1 wherein the microbubbles have a diameter of less than 200 microns. 10. The method of claim 1 wherein oxidizing gas is ozone. 11. The method of claim 1 wherein the oxidizing gas includes ozone, and oxygen included in air introduced with the ozone. 12. A method of treating an aquifer or wet soil formation, the method comprises: forming microbubbles by introducing an oxidizing gas through a microporous diffuser disposed in contact with water; introducing hydrogen peroxide to form a coating of hydrogen peroxide over the microbubbles with the microbubbles having the hydrogen peroxide coating entering the aquifer or wet soil formation. 13. The method of claim 12 wherein the hydrogen peroxide is introduced using a microporous diffuser. 14. The method of claim 13 wherein the microporous diffuser includes a nutrient and/or catalyst agent. 15. The method of claim 13 wherein the microbubbles have a diameter of less than 200 microns. 16. The method of claim 13 wherein oxidizing gas is ozone. 17. The method of claim 13 wherein the oxidizing gas includes ozone and included in the microbubbles with the ozone is air. 18. The method claim 13 wherein forming the microbubbles comprises: introducing liquid including hydrogen peroxide; introducing the oxidizing gas as an air-ozone stream through a microporous diffuser, having first centrally disposed member with sidewalls of a microporous material, that is disposed in a wet soil formation to produce microfine bubbles of water entrapping air-ozone and a second member that surrounds the first centrally disposed member and which is in fluid communication with the first centrally disposed member, with the liquid including the hydrogen peroxide introduced through a space between the tint centrally disposed member and the second member to provide the coating of the hydrogen peroxide. 19. The method of claim 13 wherein the hydrogen peroxide coating on the microbubbles promotes decomposition by adding a secondary liquid phase reactive interface as volatile compounds enter a gaseous phase.
