Water and chemical transport from a point source withinvadose zone sediments at Hanford were examined with a leak testconsisting of five 3800-liter aliquots of water released at 4.5 m depthevery week over a 4-week period. The third aliquot contained bromide, D2Oand 87Sr. Movement of the tracers was monitored for 9 months by measuringpore water compositions of samples from boreholes drilled 2-8 m from theinjection point. Graded sedimentary layers acting as natural capillarybarriers caused significant lateral spreading of the leak water. D2Oconcentrations>50 percent of the concentration in the tracer aliquotwere detected at 9-11 m depth. However, increased water contents, lowerd18O values, and geophysical monitoring of moisture changes at otherdepths signified high concentrations of leak fluids were added where D2Oconcentrations were<3 percent above background, suggesting limitedmixing between different aliquots of the leak fluids. Initially highbromide concentrations decreased more rapidly over time than D2O,suggesting enhanced transport of bromide due to anion exclusion. Nosignificant increase in 87Sr was detected in the sampled pore water,indicating strong retardation of Sr by the sediments. These resultshighlight some of the processes strongly affecting chemical transport inthe vadose zone and demonstrate the significant separation of contaminantplumes that can occur.

The first major paradigm shift in electricity generation,delivery, and control is emerging in the developed world, notably Europe,North America, and Japan. This shift will move electricity supply awayfrom the highly centralised universal service quality model with which weare familiar today towards a more dispersed system with heterogeneousqualities of service. One element of dispersed control is the clusteringof sources and sinks into semi-autonomous mu grids (microgrids).Research, development, demonstration, and deployment (RD3) of mu gridsare advancing rapidly on at least three continents, and significantdemonstrations are currently in progress. This paradigm shift will resultin more electricity generation close to end-uses, often involvingcombined heat and power application for building heating and cooling,increased local integration of renewables, and the possible provision ofheterogeneous qualities of electrical service to match the requirementsof various end-uses. In Europe, mu grid RD3 is entering its third majorround under the 7th European Commission Framework Programme; in the U.S.,one specific mu grid concept is undergoing rigorous laboratory testing,and in Japan, where the most activity exists, four major publiclysponsored and two privately sponsored demonstrations are in progress.This evolution poses new challenges to the way buildings are designed,built, and operated. Traditional building energy supply systems willbecome much more complex in at least three ways: …

The Marine Protection, Research, and Sanctuaries Act has two basic aims: to regulate intentional ocean disposal of materials, and to authorize related research. Permit and enforcement provisions of the law are often referred to as the Ocean Dumping Act. The basic provisions of the act have remained virtually unchanged since 1972, when it was enacted to establish a comprehensive waste management system to regulate disposal or dumping of all materials into marine waters that are within U.S. jurisdiction, although a number of new authorities have been added. This report presents a summary of the law.

X-ray cluster measurements interpreted with a universal baryon/gas mass fraction can theoretically serve as a cosmological distance probe. We examine issues of cosmological sensitivity for current (e.g., Chandra X-ray Observatory, XMM-Newton) and next generation (e.g., Con-X, XEUS) observations, along with systematic uncertainties and biases. To give competitive next generation constraints on dark energy, we find that systematics will need to be controlled to better than 1percent and any evolution in f_gas (and other cluster gas properties) must be calibrated so the residual uncertainty is weaker than (1+z)0.03.

This report discusses soil and water conservation topics, which are prominent in discussions of policy options for the next farm bill. Two omnibus conservation proposals have been introduced (H.R. 1551 and H.R. 1600), and many interest groups continue to offer policy recommendations ranging from general concepts to specific legislative language.

Many biological processes are carried out through the formation of macromolecular complexes, ranging from the simplest conformational organization to the most sophisticated interactions among complexes themselves. Reversible associations generate specific local conformations, active site configurations, and subunit--subunit interfaces, and encompass larger scale quaternary rearrangements and dissociation events. Assembled complexes exhibit properties different from those of component parts, such that 'the whole is greater than the sum of the parts', resulting in biological functioning of the assembly. This Gordon Research Conference brings together researchers from what may appear to be disparate fields with the common focus of applying quantitative kinetic and thermodynamic analysis to reversible macromolecular interactions. This conference will include the following session topics: (1) Protein design in evolution and recognition; (2) Emerging technologies; (3) Single molecule mechanics; (4) Nucleic acid/protein recognition; (5) Lipid/protein recognition; (6) Protein switches and networks; (7) Advances in classic technologies; (8) Ligand/macromolecule complexes and drug design; and (9) Selected student oral presentations; all from the perspective of reversibly associating systems. A wide array of techniques are typically covered, from single molecule to computational methods, chromatography and analytical ultracentrifugation, spectroscopic dynamics and titration calorimetry. The quantitative analysis of assembled complexes demonstrates that these biologically important functions …

This is one of a series of reports on Resource Conservation and Recovery Act monitoring at the 183 H basins. It fulfills a requirement of WAC 173-303-645(11)(g) to report twice each year on the effectiveness of the corrective action program. This report covers the period from July through December 2006. The current objective of corrective action monitoring is simply to track trends. Although there is short-term variability in contaminant concentrations, trends over the past 10 years are downward. The current RCRA permit and monitoring plan remain adequate for the objective of tracking trends.

This report is one of a series of semiannual groundwater monitoring reports on the corrective action program at the 300 Area process trenches. It fulfills requirements of WAC 173-303-645(11)(g) to report on the effectiveness of the corrective action program. This report covers groundwater monitoring data collected during the period from July through December 2006.

This report discusses appropriations for EPA water infrastructure programs, focusing on congressional special project designations in the account that funds these programs. While some Members of Congress, interest groups, and Administration officials are critical of these types of congressional actions actions, there is little indication that the practice will cease. Information on the programmatic history of EPA involvement in assisting wastewater treatment and drinking water projects also is provided in two appendixes.
