Patent number: 9168574Abstract: A thixotropic gel suitable for use in subsurface bioremediation is provided along with a process of using the gel. The thixotropic gel provides a non-migrating injectable substrate that can provide below ground barrier properties. In addition, the gel components provide for a favorable environment in which certain contaminants are preferentially sequestered in the gel and subsequently remediated by either indigenous or introduced microorganisms.Type: GrantFiled: June 1, 2012Date of Patent: October 27, 2015Assignee: SAVANNAH RIVER NUCLEAR SOLUTIONS, LLCInventors: Brian D. Riha, Brian B. Looney

Publication number: 20100307754Abstract: An apparatus and process for delivering aerosol-based amendments into a subsurface region is provided. The apparatus used to form the aerosol has an ability to restrict the aerosol particle size to a preferred particle size range such that undesired particle sizes are not introduced. By maintaining a proper ratio of aerosol particle size to subsurface pore size, the efficiency of an aerosol introduction can be enhanced.Type: ApplicationFiled: June 4, 2010Publication date: December 9, 2010Applicants: Savannah River Nuclear Solutions, LLC, Clemson UniversityInventors: Brian D.

Patent number: 7350428Abstract: A gas sampling apparatus and process is provided in which a standard crimping tool is modified by an attached collar. The collar permits operation of the crimping tool while also facilitating the introduction of a supply of gas to be introduced into a storage vial. The introduced gas supply is used to purge ambient air from a collection chamber and an interior of the sample vial. Upon completion of the purging operation, the vial is sealed using the crimping tool.Type: GrantFiled: June 2, 2005Date of Patent: April 1, 2008Assignee: Westinghouse Savannah River Company LLCInventors: Dennis G. Jackson, Kurt D. Peterson, Brian D. Riha

Patent number: 6591700Abstract: A system for improving the Baroball valve and a method for retrofitting an existing Baroball valve. This invention improves upon the Baroball valve by reshaping the interior chamber of the valve to form a flow meter measuring chamber. The Baroball valve sealing mechanism acts as a rotameter bob for determining mass flow rate through the Baroball valve. A method for retrofitting a Baroball valve includes providing static pressure ports and connecting a measuring device, to these ports, for measuring the pressure differential between the Baroball chamber and the well. A standard curve of nominal device measurements allows the mass flow rate to be determined through the retrofitted Baroball valve.Type: GrantFiled: February 1, 2001Date of Patent: July 15, 2003Assignee: Westinghouse Savannah River Company, LLCInventors: Dennis G. Jackson, Joseph Rossabi, Brian D. Riha

Patent number: 6367563Abstract: A device for removing a non-aqueous phase liquid from a groundwater system includes a generally cylindrical push-rod defining an internal recess therein. The push-rod includes first and second end portions and an external liquid collection surface. A liquid collection member is detachably connected to the push-rod at one of the first and second end portions thereof. The method of the present invention for removing a non-aqueous phase liquid from a contaminated groundwater system includes providing a lance including an external hydrophobic liquid collection surface, an internal recess, and a collection chamber at the bottom end thereof. The lance is extended into the groundwater system such that the top end thereof remains above the ground surface. The liquid is then allowed to collect on the liquid collection surface, and flow downwardly by gravity into the collection chamber to be pumped upwardly through the internal recess in the lance.Type: GrantFiled: June 2, 2000Date of Patent: April 9, 2002Assignee: The United States of America as represented by the United States Department of EnergyInventors: Brian B.

Patent number: 5922950Abstract: A sampling port is provided which has threaded ends for incorporating the port into a length of subsurface pipe. The port defines an internal receptacle which is in communication with subsurface fluids through a series of fine filtering slits. The receptacle is in further communication through a bore with a fitting carrying a length of tubing there which samples are transported to the surface. Each port further defines an additional bore through which tubing, cables, or similar components of adjacent ports may pass.Type: GrantFiled: October 22, 1997Date of Patent: July 13, 1999Assignee: Westinghouse Savannah River CompanyInventors: Bradley E. Pemberton, Christopher P. May, Joseph Rossabi, Brian D. Riha, Ralph L. Nichols
