A prototype Hanford barrier was deployed over the 216-B-57 Crib at the Hanford Site in 1994 to prevent percolation through the underlying waste and to minimize spreading of buried contaminants. This barrier is being monitored to evaluate physical and hydrologic performance at the field scale. This report summarizes data collected during the period FY 2005 through FY 2007. In FY 2007, monitoring of the prototype Hanford barrier focused on barrier stability, vegetative cover, evidence of plant and animal intrusion, and the main components of the water balance, including precipitation, runoff, storage, drainage, and deep percolation. Owing to a hiatus in funding in FY 2005 through 2006, data collected were limited to automated measurements of the water-balance components. For the reporting period (October 2004 through September 2007) precipitation amount and distribution were close to normal. The cumulative amount of water received from October 1994 through September 2007 was 3043.45 mm on the northern half of the barrier, which is the formerly irrigated treatment, and 2370.58 mm on the southern, non-irrigated treatments. Water storage continued to show a cyclic pattern, increasing in the winter and declining in the spring and summer to a lower limit of around 100 mm in response to …

This report documents the results of the L-Basin Corrosion Surveillance Program for the fiscal years 2005 and 2006. The water quality and basin conditions for the coupon immersion period are compared to the corrosion evaluation results from detailed metallurgical analysis of the coupons. Test coupons were removed from the basin on two occasions, March 29, 2005 and May 23, 2006, examined and photographed. Selected coupons were metallurgically characterized to evaluate the extent of general corrosion and pitting. Crystallographic and energy dispersive spectroscopy analysis were performed on a typical specimen, as-removed from the basin, to characterize the surface debris. Marked changes were noted in both the 2005 and 2006 specimens compared to previous years corrosion results. A new pitting incidence has occurred on the faces of the aluminum coupons compared to localized pitting at crevice regions only on specimens withdrawn in 2003 and 2004. The pitting incidence is attributed to sand filter fines that entered the basin on July 27, 2004 from an inadvertent backflush of the new sand filter. Pitting rate results show a trend of slowing down over time which is consistent with aluminum pit kinetics. Average pit growth rates were equal to or lower in all 2006 aluminum …

This report describes how HIV/AIDS, tuberculosis (TB), and malaria are interlinked and exacerbate efforts to control each disease, but primarily addresses funding issues related to U.S. global HIV/AIDS initiatives. It provides background information on the key U.S. agencies that implement global HIV/AIDS programs, analyzes U.S. spending on HIV/AIDS by U.S. agency and department, and presents some issues Congress might consider, particularly as debate on the President's Emergency Plan for AIDS Relief (PEPFAR) reauthorization ensues.

This report provides information on the timing of submission of the mid-session review for FY1980-FY2009, a 30-year period that covers all or part of the administrations of five Presidents, applying to the last two years of the Carter Administration, and the full terms of the Reagan, George H. W. Bush, Clinton, and George W. Bush Administrations.

The purpose of this report is to help understand how the budget increases of the last ten years have been allocated.

This report describes the issues that Congress has debated relating to The Secure Rural Schools and Community Self-Determination Act of 2000 (P.L. 106-393), which may again arise when the program expires in 2011, and explains the changes enacted for the program.

Biennial report to the Texas Legislature describing the activities of the State Office of Risk Management (SORM) during fiscal years 2006 and 2007, including information on state agency financing, claims, losses, and expenditures.

Report about the objective and goals of the Texas State Library and Archives Commission, with data for Texas public libraries statistics during fiscal years 2002-2007.

This report shows in tabular form how much the Administration requested and how much Congress appropriated during the past 11 years for U.S. payments to the multilateral development banks (MDBs). It also provides a brief description of the MDBs and the ways they fund their operations. It will be updated periodically. Three companion reports provide further information on the MDBs. See CRS Report RS20793, Multilateral Development Banks: Basic Background, CRS Report RS20791, Multilateral Development Banks: Procedures for U.S. Participation, and CRS Report RS22134 International Financial Institutions: Funding U.S. Participation.
