20090110486 | Devices and Methods for Directing Migration of Non-Aqueous Phase Liquids from Sediment - Devices and methods for directing a non-aqueous phase liquid (NAPL) that migrate entrained in a fluid (e.g., a gas) from sediments in bodies of water by using trapping caps having an upwardly sloped surface toward an accumulation zone that contains a water table, in which migration of the gas carries the NAPL toward the accumulation zone. | 04-30-2009 |
20090220304 | REMEDIATION WITH HYDROEXCAVATION AND SOLVENTS - The present invention describes methods of contaminant removal and remediation utilizing hydroexcavation in Hydroexcavation of the soil combination with solvents and/or beneficial microbes, for primary scrubbing and high pressure mixing of the soil. Various embodiments of the present invention are useful for cleaning soil with contaminants, including but not limited to hydrocarbon based materials. The solvent used in conjunction with various embodiments of the present invention comprise a degreasing composition, which may comprise sodium silicate. | 09-03-2009 |
20090232601 | Apparatus, System and Method for Remediation of Contamination - An apparatus, system and method for removing and treating contaminated materials on a bottom of a body of water and introducing growth packets to revitalize the treated bottom of the body of water. The structure may comprise a vessel with an open face. The vessel may be lowered down to the bottom of the body of water with the face facing down. As a result, the vessel and the bottom form an isolated space. The structure may comprise at least one agitating device(s) for stirring up the materials inside the vessel so as to form a mixture containing the sediment materials which in turn contain the contaminants. Multiple at least one pipe(s) may be coupled to the vessel for transporting the mixture out of the vessel for processing (filtering, treating with chemicals, etc.) so as to neutralize or eliminate the contaminants in the mixture. Then, the treated mixture can be returned to the inside of the vessel via the at least one pipe(s). | 09-17-2009 |
20100111611 | CONTAMINANT-REACTIVE GABION CAGE OR GRID STRUCTURE AND METHOD OF MANUFACTURE AND USE - Reactive gabion cage or grid structures, and their methods of manufacture, for controlling contaminants in soil, sediment or water that allow the passage of essentially non-contaminated water therethrough. The articles and methods described herein utilize gabions cages or grids, which are box shaped cages or grids (see FIG. | 05-06-2010 |
20110027017 | Carbon sequestration method - A method to create a net increase in soil organic carbon (SOC) by acidifying land applied waters with pH adjusted sulfur dioxide to open up soil pores at greater depths, while providing sulfur and other nutrients to plants and soil bacteria to stimulate and increase their overall grow and their assimilation of carbon dioxide to sequester a greater net volume increase of soil organic carbon (SOC). | 02-03-2011 |
20110076102 | METHOD AND SYSTEM FOR MOVING A LARGE TEMPORARY BUILDING - A method and system for moving a large temporary building from a first location to a second location, while the building remains erect, are disclosed. The invention is particularly suited for moving such a building during the remediation of a contaminated waste site. | 03-31-2011 |
20110305519 | SYSTEM AND PROCESS FOR EX-SITU SOIL REMEDIATION - The present invention relates generally to systems and processes for ex-situ reformulation of contaminated soil to reduce contaminant concentrations below target criteria. An ex-situ reformation system for reducing the concentration of contaminants contained in a material includes a user interface and a decision engine configured to receive a plurality of input parameters from the user interface relating to each of two or more different material stockpiles available for reformulation. The decision engine is configured to determine a quantity of each stockpile for reducing an amount of processing required to perform the reformulation. | 12-15-2011 |
20140140771 | Chemical Method and Composition for Soil Improvement - A composition for chemical soil improvement includes a synthetic fluid or base oil, a pour point depressant, polyisobutylene, and synthetic fibers, and various combinations thereof used with in situ slag. | 05-22-2014 |
