100-D Area In Situ Redox Treatability Test for Chromate-Contaminated Groundwater: FY 1998 Year-End Report (open access)

100-D Area In Situ Redox Treatability Test for Chromate-Contaminated Groundwater: FY 1998 Year-End Report

A treatability test was conducted for the In Situ Redox Manipulation (ISRM) technology at the US Department of Energy's Hanford, Washington 100D Area. The target contaminant was dissolved chromate [Cr(VI)] in groundwater. The ISRM technology involves creating a permeable subsurface treatment zone to reduce mobile chromate in groundwater to an insoluble form. The ISRM permeable treatment zone is created by reducing ferric iron [Fe(III)] to ferrous iron [Fe(II)] within the aquifer sediments. This is accomplished by injecting aqueous sodium dithionite into the aquifer and withdrawing the reaction products. The goal of the treatability test was to create a linear ISRM barrier by injecting sodium dithionite into five wells. Well installation and site characterization activities began in the spring of 1997. The first dithionite injection took place in September 1997. The results of this first injection were monitored through the spring of 1998; the remaining four dithionite injections were carried out in May through July of 1998. These five injections created a reduced zone in the Hanford unconfined aquifer 150 feet in length (perpendicular to groundwater flow) by 50 feet wide. The reduced zone extended over the thickness of the unconfined zone, which is approximately 15 feet. Analysis of recent groundwater …

2005 DOE Computer Graphics Forum Site Survey (open access)

2005 DOE Computer Graphics Forum Site Survey

The Information Management and Graphics Group supports and develops tools that enhance our ability to access, display, and understand large, complex data sets. Activities include developing visualization software for terascale data exploration; running two video production labs; supporting graphics libraries and tools for end users; maintaining four PowerWalls and assorted other advanced displays; and providing integrated tools for searching, organizing, and browsing scientific data. The Data group supports Defense and Nuclear technologies (D&NT) Directorate. The group's visualization team has developed and maintains two visualization tools: MeshTV and VisIt. These are interactive graphical analysis tools for visualizing and analyzing data on two- and three-dimensional meshes. They also provide movie production support. Researchers in the Center for Applied Scientific Computing (CASC) work on various projects including the development of visualization and data mining techniques for terascale data exploration that are funded by ASC. The researchers also have LDRD projects and collaborations with other lab researchers, academia, and industry.

2010 Census: Bureau Needs to Specify How It Will Assess Coverage Follow-up Techniques and When It Will Produce Coverage Measurement Results (open access)

2010 Census: Bureau Needs to Specify How It Will Assess Coverage Follow-up Techniques and When It Will Produce Coverage Measurement Results

A letter report issued by the Government Accountability Office with an abstract that begins "An accurate decennial census relies on finding and counting people--only once--in the right place and collecting complete and correct information. GAO reviewed the Department of Commerce's U.S. Census Bureau's (Bureau) plans to (1) improve the census's accuracy--or coverage--with its coverage follow-up operation, (2) assess the accuracy of the census through its census coverage measurement program, and (3) evaluate these efforts after 2010. GAO reviewed documentation and interviewed Bureau officials about the Bureau's coverage follow-up and measurement plans. GAO compared plans for measuring coverage in 2000 and 2010 and interviewed 15 experts about changes to the plans."

2010 Census: Census at Critical Juncture for Implementing Risk Reduction Strategies (open access)

2010 Census: Census at Critical Juncture for Implementing Risk Reduction Strategies

Testimony issued by the Government Accountability Office with an abstract that begins "In 2007, the U.S. Census Bureau (Bureau) estimated the 2010 Census would cost $11.5 billion, including $3 billion on automation and technology. At a March hearing, the Department of Commerce (Commerce) stated that the Field Data Collection Automation (FDCA) program was likely to incur significant cost overruns and announced a redesign effort. At that time, GAO designated the 2010 Decennial Census as high risk, citing long-standing concerns in managing information technology (IT) investments and uncertain costs and operations. This testimony is based on past work and work nearing completion, including GAO's observation of the address canvassing dress rehearsal. For IT acquisitions, GAO analyzed system documentation, including deliverables, cost estimates, other acquisitions-related documents, and interviewed Bureau officials and contractors. This testimony describes the implications of redesign for (1) dress rehearsal and decennial operations, (2) IT acquisitions management, and (3) Decennial Census costs."
