Abstract: The present invention provides an environmental remediation system and method. In one embodiment, the system comprises a nozzle formed from a plurality of tubulars mounted parallel with respect to each other. In one embodiment, a mixing chamber may be provided adjacent the nozzle tip to allow mixing of different fluid just before injection. In another embodiment, different fluids may remain segregated until after injection into the media. The invention may comprise electronic sensors for monitoring the reactions and other physical phenomena. The invention may comprise a control system that may control fluid flow ratios, automatically shut off pumps in response to an operator's command or in response to sensor signals detected. Fluids may be pumped sequentially through one or more tubulars into the media. A packer may be provide to keep fluid within the media. A fluid recovery system may be provided for drawing off and storing excess fluids.

Abstract: A total recovery drill assembly for providing a flowable cutting material discharging from a multiple orifice nozzle with the nozzle rotating around the longitudinal axis of the drill is provided herein. This assembly includes an outer tube that is connected to a vacuum source on a proximal end and terminates with grooves on the distal end. Within the outer tube is an inner tube that rotates within the outer tube. The proximal end of the inner tube is connected to a high pressure source for discharging a flowable material that is either a gas, a liquid or a particulate solid. The distal end of the inner tube is connected to a nozzle. The nozzle has a cutting orifice and an agitating orifice. The cutting orifice discharges the flowable material towards the grooves of the outer tube. Drilling is achieved by aiming the discharged flowable material as a laminar flow. Additionally, the nozzle has an agitating orifice designed to agitate the cut substance for removal by the vacuum.
