The main purpose of this project was to improve the fundamental mechanistic understanding and quantification of long-term colloid mobilization and colloid-facilitated transport of radionuclides in the vadose zone, with special emphasis on the semi-arid Hanford site. While we focused some of the experiments on hydrogeological and geochemical conditions of the Hanford site, many of our results apply to colloid and colloid-facilitated transport in general. Specific objectives were (1) to determine the mechanisms of colloid mobilization and colloid-facilitated radionuclide transport in undisturbed Hanford sediments under unsaturated flow, (2) to quantify in situ colloid mobilization and colloid-facilitated radionuclide transport from Hanford sediments under field conditions, and (3) to develop a field-scale conceptual and numerical model for colloid mobilization and transport at the Hanford vadose zone, and use that model to predict long-term colloid and colloid- facilitated radionuclide transport. To achieve these goals and objectives, we have used a combination of experimental, theoretical, and numerical methods at different spatial scales, ranging from microscopic investigations of single particle attachment and detachment to larger-scale field experiments using outdoor lysimeters at the Hanford site. Microscopic and single particle investigations provided fundamental insight into mechanisms of colloid interactions with the air-water interface. We could show that a …

Correspondence issued by the Government Accountability Office with an abstract that begins "Four key considerations related to ELE's availability beyond 2013 include (1) the potential for administrative savings; (2) effects on enrollment of eligible, but not enrolled, children; (3) states' level of interest in using ELE particularly for implementing PPACA; and (4) uncertainty regarding the potential for erroneous excess payments for children enrolled through ELE."

Other written product issued by the Government Accountability Office with an abstract that begins "The state and local government sector continues to face near-term and long-term fiscal challenges that grow over time. The fiscal challenges confronting the state and local sector add to the nation’s overall fiscal challenges. The fiscal situation of the state and local government sector has improved in the past year as the sector’s tax receipts have slowly increased in conjunction with the economic recovery. Nonetheless, total tax receipts have only recently returned to the prerecession levels of 2007 and the sector still faces a gap between revenue and spending. The sector faces long-term fiscal challenges that grow over time. The fiscal position of the sector will steadily decline through 2060 absent any policy changes."

Testimony issued by the Government Accountability Office with an abstract that begins "The federal-state TANF partnership makes significant resources available to address poverty in the lives of families with children. With these resources, TANF has provided a basic safety net to many families and helped many parents step into jobs. At the same time, there are questions about the strength and breadth of the TANF safety net. Many eligible families—some of whom have very low incomes—are not receiving TANF cash assistance. Regarding TANF as a welfare-to-work program, the emphasis on work participation rates as a measure of state program performance has helped change the culture of state welfare programs to focus on moving families into employment. However, features of the work participation rates as currently implemented undercut their effectiveness as a way to encourage states to engage parents, including those difficult to serve, and help them achieve self-sufficiency. Finally, states have used TANF funds to support a variety of programs other than cash assistance as allowed by law. Yet, we do not know enough about this spending or whether this flexibility is resulting in the most efficient and effective use of funds at this time."
