Abstract

A method for introducing materials into a medium including creating passages in the medium with a blast of a pure preselected compressed gas that encourages activity of a preselected entity within or introduced into the medium and maintaining the passages with preselected materials for maintaining the passages.

Claims

1. A method for introducing materials into a medium comprising the steps of:

creating at least one passage in the medium through a sudden burst of compressed gas specifically adapted to encourage activity of a preselected entity extant within the medium; and

introducing into the at least one passage a material maintaining the at least one passage;

said material maintaining the at least one passage being selected from the group consisting of anaerobic and aerobic bacteria, fungi, enzymes, bio-active sludge, cellulose, compost, diatomaceous earth, Fullers earth, barite, bentonite, and combinations thereof.

2. A method as recited in claim 1, wherein said step of creating at least one passage in the medium includes introducing into the medium at least one shock wave.

5. A method as recited in claim 1, including the step of introducing into the at least one passage at least one remediating material.

6. A method as recited in claim 1, wherein said compressed gas is oxygen gas.

3. A method for introducing materials into a medium consisting essentially of introducing into the medium a blast of a compressed gas specifically adapted to encourage activity of at least one preselected entity extant within the medium.

7. A method as recited in claim 3, wherein said compressed gas is oxygen gas.

4. A method for introducing materials into a medium consisting essentially of the steps of:

creating at least one passage in the medium with a sudden blast of a compressed gas specifically adapted to encourage activity of at least one preselected entity extant within the medium; and

introducing into the at least one passage at least one remediating material.

8. A method as recited in claim 4, wherein said compressed gas is oxygen gas.
