Abstract: The present invention is directed to a system for managing environmental audit information which includes receiving environmental audit information, accessing a predetermined set of environmental audit protocols, associating the audit information with at least one of the environmental audit protocols to form at least one environmental audit record, and storing the environmental audit record. The system of the present invention may also restrict access to the audit record, such that a quality assurance reviewer may review said audit record and may designate the status of that review, but may not modify the contents of the audit record.

Abstract: A method of separating vanadium from waste ash including generating a high temperature thermal plasma; contacting the waste ash with the high temperature thermal plasma in the presence of oxygen, thereby forming a layer of iron from iron and iron components contained within the waste ash and a layer of slag on top of the iron layer; causing vanadium contained within the waste ash to collect at an upper surface of the layer of iron and then react with the oxygen to form vanadium oxides and combine with the layer of slag; removing most of, but not all of, the layer of iron; stirring the layer of slag without addition of more of the oxygen; adding aluminum and carbon to the layer of slag; reducing or terminating power supplied to generate the high temperature thermal plasma; causing the aluminum to replace the vanadium in the vanadium oxides and causing the carbon to remove oxygen from iron oxides in the remaining portion of the layer of iron, whereby vanadium and iron combine to form a ferro-vanadium alloy.

Abstract: The invention provides a novel apparatus and method for removing liquid contaminant from a well to decontaminate a contaminated aquifer. The apparatus includes a pump capable of moving water and contaminant from below ground surface to a location above ground surface, a motor connected to drive the pump and means connected to power the motor. A water and contaminant inlet are located between the pump and the motor to accept inward flow of water and contaminant to the pump. An outlet pipe connects to the pump and extends above ground surface. A sleeve surrounds the inlet and connects between the inlet and the motor and has an opening to receive water and contaminant. The sleeve is sized to slide in and out of the well and is larger than the outlet pipe. The sleeve creates an annular space around the outlet pipe to permit passage of water and contaminant from the open end to the inlet.

Abstract: A method and apparatus for removing volatile organic contaminants from soil and waste materials including transporting and placing the contaminated material into a hopper, the hopper being substantially sealed from the atmosphere to prevent fugitive emissions of the contaminants from escaping into the atmosphere; conveying the material under substantially sealed conditions into a heated vapor stripping conveyor; conveying material under substantially sealed conditions along the vapor stripping conveyor to heat the material and thereby cause moisture in the material and the contaminants to be stripped from the material; streaming non-oxidizing gases at a controlled temperature over the material, in the direction of travel of the material, beginning at a point downstream of and adjacent to the introduction of the material into the vapor stripping conveyor to carry the contaminants and moisture away from the material; and maintaining the rate of flow and temperature of the gases to prevent undue surface drying o

Abstract: Method and apparatus for removing organic contaminants from contaminated materials including a sealed hopper, a heated vapor stripping conveyor sealed from atmospheric air to vapor strip the contaminants from the material, a sealed conveyor to convey the material in sealed condition from the hopper to the vapor stripping conveyor, a supply of non-oxidative gases at a controlled temperature for introduction into the vapor stripping conveyor, an introduction portal for the non-oxidative gases into the vapor stripping conveyor, an exit for removing the non-oxidative gases from the conveyor and located to cause the non-oxidative gases to cross currently sweep over the material to convey contaminants and moisture stripped from the material out of the vapor stripping conveyor, and a controller for controlling the flow rate and temperature of the non-oxidative gases as they flow through the vapor stripping conveyor and to prevent undue surface drying of the material as the material passes through the vapor stripping

Abstract: A method of removing volatile contaminants from a layer of contaminant lying on the top of a water table and in an unsaturated zone including opening a hole into the unsaturated zone and downwardly to at least the top of the layer of contaminant, positioning the end of a solid, air impermeable hollow pipe into the hole and adjacent to air permeable fill material, establishing an airtight seal around the pipe at the hole, reducing the pressure in the pipe in the hole to cause air and contaminant vapors to flow along the layer of contaminant and through the unsaturated zone and into the hole and through the air permeable fill material, and removing air and contaminant vapors from the hole through the pipe.

Abstract: Decontamination is provided by establishing a borehole into the vadose zone, introducing porous fill material into the borehole, positioning a hollow conduit into the borehole, and applying suction to the conduit and the borehole to reduce pressure and cause air and contaminant vapors to move through the vadose zone and into the borehole and through the porous fill material contained therein.

Abstract: A method and apparatus for removing volatile organic contaminants from soil including removing contaminated soil from the earth; transporting and placing the contaminated soil into a soil hopper, the hopper being substantially sealed from the atmosphere to prevent fugitive emissions of the contaminants from escaping into the atmosphere; conveying the soil under sealed conditions into a heated vapor stripping conveyor having moving flights; conveying the soil under sealed conditions along the vapor stripping conveyor and in close contact with the flights to heat the soil to a temperature below the boiling temperatures of the contaminants, thereby causing moisture in the soil and the contaminants to be stripped from the soil; streaming non-oxidizing gases having a greater than ambient temperature across the surface of the soil to carry the contaminants and moisture across and away from the soil; and maintaining the rate of flow and temperature of the gases to prevent undue surface drying of the soil as the soil

Abstract: A method of detoxifying a component of contaminated soil containing a halogenated organic compound including contacting the contaminated soil with atomic hydrogen in an amount effective to react with halogen contained in the compound and substituting the hydrogen for the halogen.

Abstract: Apparatus and method for removing volatile and semi-volatile organic contaminants from natural soil containing moisture by sealing the soil in a stripping conveyor against contact with air and vapor stripping the contaminants at a temperature below the boiling temperatures of the contaminants.
