摘要： A system and method for remediation of contaminated soil is provided. The system comprises a soil remediation cell of contaminated soil, and a plurality of multi-functional perforated pipes located within the contaminated soil. The multi-functional perforated pipes operate as (a) heating elements for introducing heat into the contaminated soil for volatilizing the contaminants located within the contaminated soil without utilizing mechanically driven forced air thereby producing a contaminated vapor, and (b) flow channels for removing the contaminated vapor from within the soil remediation cell. A high temperature covering, located about the soil remediation cell, forms a chamber over the soil remediation cell which receives and collects in the chamber the contaminated vapor which have been released from the multi-functional perforated pipes. Means for collecting and/or destroying contaminants in the contaminated vapors collected in the storage chamber can also be employed in conjunction with the soil remediation cell.

摘要： An improved deep remediation injection system for in-situ remediation of contaminated soil and ground water. The system includes a soil penetrating lance for injecting at least two different highly-pressurized fluids taken from the group of air, gaseous oxygen, ozone, oxygenated liquid, hydrogen peroxide, surfactant-containing liquid, catalyst-containing liquid and suspended biologicals-containing liquids, or a liquid containing other chemicals, into said contaminated soil as said soil penetrating lance is inserted for penetration therein. The soil penetrating lance has at least an upper set of injection ports, the upper set of injection ports being generally radially spaced-apart on said lance, and at least one lower set of injection ports, the lance having an average width in the vicinity of the upper set of injection ports. The lance further includes substantially fluidically-independent first and second conduits leading, respectively, to the lower set of injection ports and the upper set of injection ports so as to permit delivery of separate pressurized fluid streams to the upper and lower sets of injection ports and then into the soil. The upper and lower sets of injection ports are spaced apart from each other on said lance a distance no farther than about three times the average width of said lance in the vicinity of the upper set of injection ports.

摘要： A cover assembly for an organic waste lagoon basin and a method of making and deploying such a cover assembly. A cover includes connected cover panels or sections. In one form of the invention the panels are comprised of a single layer of geotextile fabric. In another form of the invention the panels are comprised of interconnected strata including a sacrificial layer which faces the sun and protects the cover from ultraviolet light degradation; a foam layer that floats the cover; and a geotextile fabric layer. The geotextile fabric is porous and suppresses the release of malodorous gases from the lagoon basin. The cover can be constructed and deployed by laying out cover panels in fanfold fashion along a side of the basin; connecting adjacent edges of the panels; attaching flotation to the free edge of the top panel; and using deployment lines and a mandrel to move the cover across the filled basin.

摘要： A method of remediating a site of earth and groundwater contamination includes the steps of drilling at least one injection well, and preferably a plurality of injection wells, into the groundwater in a contaminated area. At least one, and preferably a plurality of extraction wells, are drilled into the earth above the groundwater, the vadose zone, in the contaminated area. The surface of the earth above the contaminated area is sealed, such as by a layer of concrete, asphalt, or plastic sheeting. Air and nutrients are injected into the contaminated area through the injection wells. The air is injected on a substantially continuous basis while the nutrients are injected on a batch basis. Air and vapor is extracted on a substantially continuous basis from the contaminated area by the extraction wells, which may be either vertically or horizontally positioned.

摘要： Inexpensive, highly effective methods for the in-situ reduction of hexavalent chromium to the non-toxic trivalent oxidation state in soil and groundwater containing hexavalent chromium are provided, which may reduce hexavalent chromium concentration in soil to as low as 5 mg/L. The methods involve sampling soil comprising hexavalent chromium to determine a reaction amount of a reducing agent, providing a frame on a top surface of the soil, wetting the soil, spreading a reducing agent on the top surface of the soil, and flushing the soil with water to dissolve the reducing agent. The reducing agent may be a chemical agent, a biological agent, or a combination of chemical and biological agents. The biological reducing agents may include sludge from wastewater, return activated sludge, waste activated sludge, leachate from landfill or from composting operations, or compost material from municipal wastewater, industrial wastewater, or solid waste operations.
