Abstract: A pressure extraction process for removal of underground contaminants from subsurface soil and groundwater comprises establishing a well through the unsaturated soil into the underlying groundwater unit, with the well including an exterior pipe having fluid permeable openings therein at a lower portion that extends above and below the groundwater surface. An interior pipe is provided inside the exterior pipe and has an inlet opening below the groundwater surface. Oxygen-containing gas is injected into the exterior pipe at a non-vacuum pressure. Preferably the pressure is sufficient to cause some of the gas to flow outwardly into the soil through the pipe openings. A gas pressure flow is established downwardly in the exterior pipe to the inlet of the interior pipe and then upwardly through the interior pipe and out of the well.
Abstract: An improved animal lure and cover scent process and product employs a combustible absorbent material impregnated with an aromatic substance having fragrance attractive to an animal, with the absorbent material being of restricted combustibility such that the absorbent material tends to smoke without producing a flame as it burns, the smoke entraining the fragrance with it as it travels through the air. The combustible absorbent material of the present invention is in the form of an incense stick wherein a cellulosic material formed from sawdust is coated on one end of a combustible bamboo stick. A weather shield protects the incense stick from wind and rain.
