Abstract: An apparatus for pneumatically fracturing a soil formation, and thereafter utilizing or maintaining the fracture network thus formed by continuous injection of a gas stream into the fracture network, and introducing into that gas stream dry media which is entrained in the gas stream and thereby dispersed and distributed through the soil formation in substantially predictable or predetermined patterns, is described. The fracture network and/or the dry media contained therein create or enhance usefulness for a given purpose with respect to the soil formation.

Abstract: In preferred embodiments, an apparatus and method for enhancing the in situ removal of at least one contaminant from a contaminated body, the body being provided with at least one interstice, by generating and focusing vibrations toward the interstice, thereby exciting the contaminant within the body, whereby transport of the contaminant out of the body is facilitated. Preferably, the vibrations are sonic or ultrasonic. Vacuum extraction or transformation of the contaminant may also be effected.

Abstract: A method for pneumatically fracturing a soil formation, and thereafter utilizing or maintaining the fracture network thus formed by continuous injection of a gas stream into the fracture network, and introducing into that gas stream dry media which is entrained in the gas stream and thereby dispersed and distributed through the soil formation in substantially predictable or predetermined patterns, is described. The fracture network and/or the dry media contained therein create or enhance usefulness for a given purpose with respect to the soil formation. The method utilizes novel apparatus, especially high velocity nozzles which are substantially planar or directional and can be used in combination with the borehole casing to achieve a variety of fracturing and dry media injection effects.

Abstract: A method and apparatus are disclosed for reducing or eliminating non-naturally occurring, subsurface, liquid contaminants from one or more soil formations, which involves the steps of pneumatically fracturing the soil formation to produce a fracture network; simultaneously or subsequently inserting into said fracture network and throughout adjacent portions of the soil formation, a pressurized gas stream, and introducing into the pressurized gas stream a mixture of one or more liquid amendments, wherein said pressurized gas, in conjunction with said liquid amendments, has an oxygen or other electron acceptor content sufficient to promote the growth of aerobic or other microorganisms in said fracture network, and wherein the pressurized gas has a sufficiently high gas to liquid ratio to atomize the liquid amendments, whereby the amendments are distributed throughout the soil formation.

Abstract: Apparatus for eliminating non-naturally occurring, subsurface, liquid toxic contaminants from soil, includes a fracturing assembly for pneumatically fracturing the soil, the fracturing assembly including a tubular probe which receives a pressurized gas, the probe including a soil penetrating portion adapted to be inserted in a well in the soil and an above soil portion in fluid communication with the soil penetrating portion, the soil penetrating portion including a tube which receives the pressurized gas, first and second packers connected with the tube for pressing against walls of the well so as to provide a sealed area in the well between the first and second packers, a nozzle position in the sealed area in fluid communication with the tube for supplying the pressurized gas into the soil, the nozzle including at least one orifice therein which fluidly connects the soil with the tubular probe and an adjustment assembly which permits relative movement between the first and second packers in response to soil
