An apparatus for treating subsurface water comprising:
- a microporous diffuser comprising:
- a first cylindrical member and a second cylindrical member, each of the first and second cylindrical members having sidewalls comprising a plurality of micropores, the second cylindrical member being coaxially disposed within the first cylindrical member, the first and second cylindrical members being disposed in the subsurface water to deliver at least a first fluid and a second fluid to the first and second cylindrical members, respectively, with one of the fluids forming a coating over the other of the fluids;
- an ozone generator;
- an air compressor;
- and
- a control mechanism to deliver an air and ozone (O3) mixture from the ozone generator and air compressor to one of the first and second cylindrical members as one of the fluids;
- wherein the first and second fluids are different from the subsurface water.
