Book Description
When waterfowl began to die from selenium poisoning at Kesterson National Wildlife Refuge in California's San Joaquin Valley, considerable alarm arose among environmental and agricultural specialists. This new volume suggests that Kesterson is not a unique problem and the events there offer important lessons for the future. Irrigation-Induced Water Quality Problems uses the San Joaquin experience to suggest how we can prepare for similar problems elsewhere. As one committee member put it, "There will be elsewheres"â€"trace elements and organic contaminants are being concentrated by irrigation in many river basins. This book addresses how the Kesterson crisis developed, how irrigation can endanger water quality, and how economic, legal, and other factors impede our ability to respond to water quality problems. The committee explores how to study these problems, unraveling complex issues and clarifying the varying perspectives of farmers, environmentalists, scientists, and other key figures. This dispassionate analysis of a controversial topic will be useful to policymakers, resource managers, and agricultural specialists and farmers, as well as specialists in hydrology, water quality, irrigation, law, and environmental quality. It will also be useful as a case study in the environmental policy classroom.

Book Description
The Department of Toxic Substances Control (DTSC) of the State of California Environmental Protection Agency is in the process of complying with the Regulatory Structure Update. The Regulatory Structure Update is a comprehensive review and refocusing of California's system for identifying and regulating management of hazardous wastes. As part of this effort, the DTSC proposes to change its current waste classification system that categorizes wastes as hazardous or nonhazardous based on their toxicity. Under the proposed system there would be two risk-based thresholds rather than the single toxicity threshold currently used to distinguish between the wastes. Wastes that contain specific chemicals at concentrations that exceed the upper threshold will be designated as hazardous; those below the lower threshold will be nonhazardous; and those with chemical concentrations between the two thresholds will be "special" wastes and subject to variances for management and disposal. The proposed DTSC system combines toxicity information with short or long-term exposure information to determine the risks associated with the chemicals. Under section 57004 of the California Health and Safety Code, the scientific basis of the proposed waste classification system is subject to external scientific peer review by the National Academy of Sciences, the University of California, or other similar institution of higher learning or group of scientists. This report addresses that regulatory requirement.

Book Description
Over the past 25 years, the United States has made support for the spread of democracy to other nations an increasingly important element of its national security policy. These efforts have created a growing demand to find the most effective means to assist in building and strengthening democratic governance under varied conditions. Since 1990, the U.S. Agency for International Development (USAID) has supported democracy and governance (DG) programs in approximately 120 countries and territories, spending an estimated total of $8.47 billion (in constant 2000 U.S. dollars) between 1990 and 2005. Despite these substantial expenditures, our understanding of the actual impacts of USAID DG assistance on progress toward democracy remains limited-and is the subject of much current debate in the policy and scholarly communities. This book, by the National Research Council, provides a roadmap to enable USAID and its partners to assess what works and what does not, both retrospectively and in the future through improved monitoring and evaluation methods and rebuilding USAID's internal capacity to build, absorb, and act on improved knowledge.

Book Description
TRB's Airport Cooperative Research Program (ACRP) Synthesis 22: Common Airport Pavement Maintenance Practices explores how airports implement a pavement maintenance management program, including inspecting and tracking pavement condition, scheduling maintenance, identifying necessary funds, and treating distresses in asphalt and concrete pavements.

Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 433: Significant Findings from Full-Scale Accelerated Pavement Testing documents and summarizes significant findings from the various experimental activities associated with full-scale accelerated pavement testing (f-sAPT) programs that have taken place between 2000 and 2011. The report also identifies gaps in knowledge related to f-sAPT and where future research may be needed. NCHRP Synthesis 433 is designed to expand the f-sAPT base of knowledge documented in NCHRP Syntheses 325 and 235, both with the same title of Significant Findings from Full-Scale Accelerated Pavement Testing. f-sAPT is the controlled application of a wheel loading, at or above the appropriate legal load limit, to a pavement system to determine pavement response in a compressed time period. The acceleration of damage is achieved by one or more of the following factors: increased repetitions, modified loading conditions, imposed climatic conditions, and thinner pavements with a decreased structural capacity which have shorter design lives"--

Book Description
Congress requested that the U.S. Department of Homeland Security (DHS) produce a site-specific biosafety and biosecurity risk assessment (SSRA) of the proposed National Bio- and Agro-Defense Facility (NBAF) in Manhattan, Kansas. The laboratory would study dangerous foreign animal diseases-including the highly contagious foot-and-mouth disease (FMD), which affects cattle, pigs, deer, and other cloven-hoofed animals-and diseases deadly to humans that can be transmitted between animals and people. Congress also asked the Research Council to review the validity and adequacy of the document. Until these studies are complete, Congress has withheld funds to build the NBAF. Upon review of the DHS assessment, the National Research Council found "several major shortcomings." Based on the DHS risk assessment, there is nearly a 70 percent chance over the 50-year lifetime of the facility that a release of FMD could result in an infection outside the laboratory, impacting the economy by estimates of $9 billion to $50 billion. The present Research Council report says the risks and costs of a pathogen being accidently released from the facility could be significantly higher. The committee found that the SSRA has many legitimate conclusions, but it was concerned that the assessment does not fully account for how a Biosafety-Level 3 Agriculture and Biosafety-Level 4 Pathogen facility would operate or how pathogens might be accidently released. In particular, the SSRA does not include important operation risks and mitigation issues, such as the risk associated with the daily cleaning of large animal rooms. It also fails to address risks that would likely increase the chances of an FMD leak or of the disease's spread after a leak, including the NBAF's close proximity to the Kansas State University College of Veterinary Medicine clinics and KSU football stadium or personnel moving among KSU facilities.

Book Description
Introduction to Veterinary and Comparative Forensic Medicine is a ground-breaking book in an emerging new speciality. It reflects the increasing demand for expert opinion by veterinarians and others in courts of law and elsewhere on such matters as: · wildlife conservation, · welfare of, and alleged cruelty to, animals, · insurance, certification and malpractice · the identification of live and dead species or their derivatives. It also discusses and analyses current concern over possible links between domestic violence and abuse of animals. Throughout the book the emphasis is on the need for a systematic and thorough approach to forensic work. A particular feature is practical advice, with protocols on dealing with common problems, together with case studies, various appendices and an extensive bibliography. A vital reference for members of the veterinary profession, lawyers, enforcement bodies and welfare and conservation organisations. The comparative aspects provide an important source of information for those working in human forensic medicine and the biological sciences.
