Abstract: A method for preparing a contaminated structure comprising particulates for collection of one or more liquid contaminants, including: drilling one more bore holes through the contaminated structure using one or more drill rods that remain within the bore hole; attaching a horizontal soil cutting blade to one end of the one or more drill rods, wherein the horizontal soil cutting blade comprises a cutting portion and a non-cutting portion, and wherein the non-cutting portion has attached thereto an impermeable geotextile; retrieving the one or more drill rods from the bore hole such that the cutting portion of the horizontal soil cutting blade is drawn through the contaminated structure creating a void therein, and such that the impermeable geotextile is drawn through the void; and introducing a contaminant collection apparatus at or along one edge of the impermeable geotextile, such that an upper surface of the impermeable geotextile is in fluid communication with the contaminant collection apparatus.

Abstract: This invention is directed to methods for treating radioactive-containing waste materials. Even more specifically, this invention relates to the prevention of radon emissions by encapsulating the radon in radon-generating waste matter using a chemical additive. Alternatively, the amount of radon escaping into the environment may be minimized by adjusting the shape of the carrier which stores the radon generating waste matter. Additionally, the first two embodiments may be combined to ensure that the radon does not escape into the environment. Finally, polymer sealants may be used as an additional barrier layer.

Abstract: The present invention is directed to a method for removing selenium from a waste stream. The process is a multi-step process that removes selenium from a waste stream in the form of barium selenate and/or barium selenite. In a further step, the barium selenate and/or barium selenite forms a complex precipitate with barium sulfate, which encapsulates the barium selenate and/or barium selenite. The complex precipitate is subsequently removed from the waste stream.
