Incorporating management with science and modeling, the book covers all areas of groundwater resource assessment, modeling, and management, and combines hands-on applications with relevant theory. For Water Resource Managers and Decision Makers The book describes techniques for the assessment of groundwater potential, pollution, prevention, and remedial measures, and includes a new approach for groundwater modeling based on connections (network theory). Approximately 30 case studies and six hypothetical studies are introduced reflecting a range of themes that include: groundwater basics and the derivation of groundwater flow equations, exploration and assessment, aquifer parameterization, augmentation of aquifer, water and environment, water and agriculture, the role of models and their application, and water management policies and issues. The book describes remote sensing (RS) applications, geographical information systems (GIS), and electrical resistivity methods to delineate groundwater potential zones. It also takes a look at: Inverse modeling (pilot-points method) Simulation optimization models Radionuclide migration studies through mass transport modeling Modeling for mapping groundwater potential Modeling for vertical 2-D and 3-D groundwater flow Groundwater Assessment, Modeling, and Management explores the management of water resources and the impact of climate change on groundwater. Expert contributors provide practical information on hydrologic engineering and groundwater resources management for students, researchers, scientists, and other practicing professionals in environmental engineering, hydrogeology, irrigation, geophysics, and environmental science.










Strengthening Forensic Science in the United States


Book Description

Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.




Inevitably Toxic


Book Description

Not a day goes by that humans aren’t exposed to toxins in our environment—be it at home, in the car, or workplace. But what about those toxic places and items that aren’t marked? Why are we warned about some toxic spaces' substances and not others? The essays in Inevitably Toxic consider the exposure of bodies in the United States, Canada and Japan to radiation, industrial waste, and pesticides. Research shows that appeals to uncertainty have led to social inaction even when evidence, e.g. the link between carbon emissions and global warming, stares us in the face. In some cases, influential scientists, engineers and doctors have deliberately "manufactured doubt" and uncertainty but as the essays in this collection show, there is often no deliberate deception. We tend to think that if we can’t see contamination and experts deem it safe, then we are okay. Yet, having knowledge about the uncertainty behind expert claims can awaken us from a false sense of security and alert us to decisions and practices that may in fact cause harm. In the epilogue, Hamilton and Sarathy interview Peter Galison, a prominent historian of science whose recent work explores the complex challenge of long term nuclear waste storage.




The San Joaquin Kit Fox


Book Description

The San Joaquin Kit Fox introduces readers to a small wild canid that occupies a prominent position in ongoing conservation battles. Native to central California, where land is in high demand for development purposes, the San Joaquin kit fox population has been significantly impacted by profound habitat loss. The species remains on the original US endangered species list issued in 1966, with dim prospects for recovery. To guide the work of researchers and conservationists, Brian L. Cypher synthesizes the biological and ecological data collected to date on this species and documents both historical and contemporary efforts to protect it. He details the species' evolutionary and taxonomic history, distribution and habitat preferences, mortality sources, and more. In doing so, he draws out the ever-changing relationship between San Joaquin kit foxes, people, and land use. Richly illustrated and accessible, The San Joaquin Kit Fox is a necessary reference for students, researchers, and conservationists looking to better understand this charismatic creature and others like it in order to better secure the futures of these species.




Planetary Health


Book Description

Human health depends on the health of the planet. Earth’s natural systems—the air, the water, the biodiversity, the climate—are our life support systems. Yet climate change, biodiversity loss, scarcity of land and freshwater, pollution and other threats are degrading these systems. The emerging field of planetary health aims to understand how these changes threaten our health and how to protect ourselves and the rest of the biosphere. Planetary Health: Protecting Nature to Protect Ourselves provides a readable introduction to this new paradigm. With an interdisciplinary approach, the book addresses a wide range of health impacts felt in the Anthropocene, including food and nutrition, infectious disease, non-communicable disease, dislocation and conflict, and mental health. It also presents strategies to combat environmental changes and its ill-effects, such as controlling toxic exposures, investing in clean energy, improving urban design, and more. Chapters are authored by widely recognized experts. The result is a comprehensive and optimistic overview of a growing field that is being adopted by researchers and universities around the world. Students of public health will gain a solid grounding in the new challenges their profession must confront, while those in the environmental sciences, agriculture, the design professions, and other fields will become familiar with the human consequences of planetary changes. Understanding how our changing environment affects our health is increasingly critical to a variety of disciplines and professions. Planetary Health is the definitive guide to this vital field.




Hydraulic Fracturing for Oil and Gas


Book Description

This final report provides a review and synthesis of available scientific information concerning the relationship between hydraulic fracturing activities and drinking water resources in the United States. The report is organized around activities in the hydraulic fracturing water cycle and their potential to impact drinking water resources. The stages include: (1) acquiring water to be used for hydraulic fracturing (Water Acquisition), (2) mixing the water with chemical additives to prepare hydraulic fracturing fluids (Chemical Mixing), (3) injecting the hydraulic fracturing fluids into the production well to create fractures in the targeted production zone (Well Injection), (4) collecting the wastewater that returns through the well after injection (Produced Water Handling), and (5) managing the wastewater via disposal or reuse methods (Wastewater Disposal and Reuse). EPA found scientific evidence that hydraulic fracturing activities can impact drinking water resources under some circumstances. The report identifies certain conditions under which impacts from hydraulic fracturing activities can be more frequent or severe.
