ABSTRACT:
Method and apparatus for treating confined material such as buried waste or areas of contaminated earth by injecting a plurality of high velocity jets of treating fluid into the material over a limited depth in multiple direction from each of a plurality of injection holes. The high velocity jets remain stationary, but the arrangement of the jets emanating from an injection hole in multiple directions produces a result similar to a rotating jet but with increased penetrating force. The jets are operated sequentially over the limited depth of each injection hole to treat a layer of the material and are then moved and again operated sequentially over another limited depth of each injection hole to provide treatment of the material by layers. This allows effective treatment of material surrounding each injection hole without substantial interference from treating fluid flowing through the material from a previously treated hole. It is preferred that each injection hole be lined during installation with a material that is easily cut by the high velocity jets so that the jets pass from a source inside the lined injection hole, through the lining, and into the material to be treated surrounding the hole.
