Readers with an interest in environmental science, geography, oceanography, marine biology, environmental biology, aquatic pollution and ecology will find the research presented here most appealing. Readers will discover critical aspects of the chemistry of the estuarine water (particularly that of Hooghly and Matla estuaries) in the lower stretch of the delta region along with the causes and effects of pollution in and around this region. Particular attention is given to the bioaccumulation of conservative pollutants in edible fishes and floral communities thriving in this region. Several case studies are also incorporated to highlight the vulnerability of pollution in this region. Chapters also address the impacts of climate change (specifically acidification) on the concentration and behavior of conservative pollutants. Finally, the book highlights some mitigation measures at the technology and policy level to minimize the negative impacts posed by different groups of pollutants on the estuarine biodiversity.

Water is a paramount determinant of quality of life. The WHO experts believe that the sickness and death rates of the world population could be reduced by 75% by maintaining good quality of drinking water. That is why thirty-one leading scientists and specialists from fifteen countries gathered in November 2003 at the NATO Advanced Research Workshop (ARW) on "Modern Tools and Methods of Water Treatment for Improving Living Standards" in Dnepropetrovsk, Ukraine, to discuss the scientific concepts and practical means for the solution of the complex social, economic and ecological problems associated with water purification, consumption, conservation, and protection. All this is covered in this book of proceedings of the NATO ARW.

This book contains four parts. In Part 1, the readers will find recent advances in drinking water treatment in the United States, biological control in water-cooling towers, analytical control of drinking water quality, and the use of radionuclides for monitoring global contamination. In Part 2, some innovative methods and tools, such as electrochemically-stimulated sorption and sorption-membrane methods, a bubble-extraction method, fibroid sorbents, in-situ oxygen curtain technology, use of ion-exchange membranes, electrochemically-generated silver and copper ions and colloidal gold for water purification and post-purification are presented. In Part 3, recent studies into the treatment of wastewaters could be found. Among them: water reclamation and recycling in Danish industry, biocide polymers as a new opportunity in water treatment, optimization of galvanic wastewater treatment processes, efficiency of nitrification and denitrification processes inwastewater treatment plants, electrochemical processes for wastewater purification employing fluidized beds of particles, cold plasma as a new tool for purification of wastewater from chemical contaminants, bacteria and viruses. In Part 4, examples of management of water resources in the United Kingdom, Bulgaria, Poland, Croatia, and Romania using a variety of case studies are presented. Also, the important issue of industry-university cooperation for postgraduate education and training in the water treatment area is discussed.

We believe that this book will be helpful to the international community of scientists, specialists and students dealing with water treatment, purification, conservation and protection.

This book examines the role of The International Maritime Organization (IMO) in the prevention and control of pollution of the marine environment from vessels with a particular reference to the current north-south tensions regarding the strategy for combating climate change in the maritime sector as well as the prevention of marine pollution from the ship-breaking industry. The IMO, a United Nations specialized agency, has been entrusted with the duty to provide machinery for cooperation among governments for the prevention and control of pollution of the marine environment from vessels. The organization is responsible for drafting legal instruments as well as for facilitating technical cooperation for the protection of the marine environment. Although IMO legal instruments are mainly targeted at the prevention of pollution of the marine environment from vessels, there is a trend towards a liberal interpretation of this, and the organization has expanded its work to areas like shipbreaking, which is essentially a land-based industry.

This book highlights the application of Geographical Information System (GIS) and nature based algorithms to solve the problems of water and water based renewable energy resources. The irregularity in availability of resources and inefficiency in utilization of the available resources has reduced the potentiality of water and water based renewable energy resources. In recent years various soft computation methods (SCM) along with GIS were adopted to solve critical problems. The book collects various studies where many SCMs were used along with GIS to provide a solution for optimal utilization of natural resources for satisfying the basic needs of the population as well as fulfilling their burgeoning energy demands. The articles depict innovative application of soft computation techniques to identify the root cause and to mitigate the uncertainty for optimal utilization of the available water resources. The advantage of SCM and GIS were used to maximize the utilization of water resources under cost and time constraints in face of climatic abnormalities and effect of rapid urbanization.

The NATO Advanced Research Workshop, "Decision Support for Natural Disasters and Intentional Threats to Water Security" was the result of close collaboration between environmental, security, water resource, and health officials in the United States and Croatia. The premise of the Workshop is that multiple, disparate threats to water security exist, and that shared decision support structures provide effective means for avoiding and responding to potential or actual situations. The Workshop was co-directed by Professors Tissa Illangasekare of the Colorado School of Mines, and Dragutin Geres of Hrvatske vode. The Workshop was organized into a series of case studies, presentation of management tools, or a combination of the two. Presentations were further organized as to (1) Natural Occurrences, (2) Anthropogenic Causes, and (3) Decision Support Tools. Delegates from eleven countries assembled to explore these topics at the Hotel Dubrovnik President in Dubrovnik from April 22-25, 2007. A total of thirty delegates from NATO, Partner, Mediterranean Dialog, or other countries were in attendance. The final program included technical sessions using a presentation and dialog format, a field trip, and networking sessions. There were twenty five technical presentations supported by seventeen formal papers (many updated in late-2008 and 2009), and these form the basis for these proceedings. xi ACKNOWLEDGEMENTS The co-directors and organizers of this Advanced Research Workshop a- nowledge the NATO Science Programme for major financial support and for providing detailed guidance on how best to organize and execute a meeting of this nature.

When Europeans first arrived at what is now California's San Joaquin Valley, they found a vast landscape of wetlands, small ponds, riparian forests, and grasslands surrounding three large swampland lakes. What greets a visitor to the region today is a dramatically different view of mile after mile of row crops, vineyards, orchards, and grazing acreage - some of the most fertile and productive agricultural land in the world. This remarkable transformation, with its enduring consequences, is at the center of Ruling the Waters, a legal, social, and environmental history of how western water law shaped, and was shaped by, the subjugation of the largest freshwater wetlands wildlife habitat in the West. At the heart of efforts to wrest arable land from the region was the Kern River, which rises in the Sierra Nevada and carries snowmelt to what was once a great network of lakes, sloughs, and marshes at the southern end of California's Central Valley. In Ruling the Waters Douglas R. Littlefield describes how, over the course of the nineteenth and early twentieth centuries, pioneers and entrepreneurs diverted water out of this network of waterways to extract gold in the mountains and irrigate farms lower down the river, and how the law was made to accommodate these practices. Struggles over the Kern River's water established one of the most important concepts in water law in some parts of the United States - that prior appropriation, dependent on the chronological order of diversions from waterways, could legally coexist with riparian rights, which restrict water usage to landownership directly next to a river or stream. Littlefield traces this concept to the 1886 California Supreme Court case of Lux v. Haggin - which pitted the giant farming and cattle company of Miller & Lux against a prominent land baron, James B. Haggin - and shows how the lawsuit profoundly shaped future waters issues, which in turn influenced water laws in other western states that were grappling with similar questions. Far from a dry legal history, Ruling the Waters tells a story with world-wide historical environmental ramifications, a tale of competing personalities and values and visions that forever changed both the economy and the ecology of the American West.

This book deals with water management, one of the most challenging issues of contemporary society. Research and innovation in the field of water management must address certain fundamental aspects: access to water, water quality, water treatment, transboundary effect of water, etc. A comprehensive analysis was performed in a national research program of Moldova, entitled "Research and management of water quality". The main goal of the research program was to create and improve the legal, scientific and methodological, technological basis and sustainable development of water, implementation of modern technologies in water supply, treatment and reuse. Other priorities include expansion of access to water sources, improvement of environmental protection, especially water protection against pollution and depletion, efficient water use and establishing an effective monitoring system for disaster prevention. The topics concern research of water structure and quality, surface water, groundwater, water treatment, irrigation technologies and water pollution by remains from industry, one of the main environmental problems of our time. The book helps to get to coherent water policies of states.

This open access textbook provides a concise introduction to economic approaches and mathematical methods for the study of water allocation and distribution problems. Written in an accessible and straightforward style, it discusses and analyzes central issues in integrated water resource management, water tariffs, water markets, and transboundary water management. By illustrating the interplay between the hydrological cycle and the rules and institutions that govern today's water allocation policies, the authors develop a modern perspective on water management. Moreover, the book presents an in-depth assessment of the political and ethical dimensions of water management and its institutional embeddedness, by discussing distribution issues and issues of the enforceability of human rights in managing water resources. Given its scope, the book will appeal to advanced undergraduate and graduate students of economics and engineering, as well as practitioners in the water sector, seeking a deeper understanding of economic approaches to the study of water management.

The main objective of the Water Framework Directive in the European countries is to achieve a good status of all the water bodies, in the integrated management of river basins. In order to assess the impact of improvement measures, water quality models are necessary. During the previous decades the progress in computer technology and computational methods has supported the development of advanced mathematical models for pollutant transport in rivers and streams. This book is intended to provide the fundamental knowledge needed for a deeper understanding of these models and the development of new ones, which will fulfil future quality requirements in water resources management. This book focuses on the fundamentals of computational techniques required in water quality modelling.

Advection, dispersion and concentrated sources or sinks of contaminants lead to the formulation of the fundamental differential equation of pollutant transport. Its integration, according to appropriate initial and boundary conditions and with the knowledge of the velocity field, allows for pollutant behaviour to be assessed in the entire water body. An analytical integration is convenient only in one-dimensional approach with considerable simplification. Integration in the numerical field is useful for taking into account particular aspects of water body and pollutants.

To ensure their reliability, the models require accurate calibration and validation, based on proper data, taken from direct measurements. In addition, sensitivity and uncertainty analysis are also of utmost importance.

All the above items are discussed in detail in the 21 chapters of the book, which is written in a didactic form for professionals and students.

The annual cost of medical care in the U niled States is rapidly approaching a trillion dollars. Without doubt, much of the rise in costs is due to our health industry's concentration on high technology remediation and risk avoidance measures. From recent public discussions it is becoming in creasingly evident that to contain the costs and at the same time extend the benefits of health care without national bankruptcy will necessitate much greater attention to preventative medicine. The total cost of waste disposal by our health industry is well over a billion dollars. It is rising rapidly as we increasingly rely on high technol ogy remediation measures. Here, too, in the opinion of the authors of this work, it would be prudent to give much greater attention to preventative approaches. Incineration technology has largely been developed for disposing mu nicipal solid waste (MSW) and hazardous waste (HW). As a result of the multibillion dollar funding for the Resource Conservation and Recovery Act (RCRA), most experts believe that pollution control is the key to minimizing toxic emissions from incinerators. This view is now beginning to take hold in medical waste (MW) incineration as well. However, the authors contributing to this book have concluded that precombustion measures can be most effective in reducing the toxic products of medical waste incineration."

Toxic substances threatens aquatic and terrestrial ecosystems and ultimately human health. The book is a thoughtful effort in bringing forth the role of biotechnology for bioremediation and restoration of the ecosystems degraded by toxic and heavy metal pollution. The introductory chapters of the book deal with the understanding of the issues concerned with the pollution caused by toxic elements and heavy metals and their impacts on the different ecosystems followed by the techniques involved in monitoring of the pollution. These techniques include use of bio-indicators as well as modern techniques for the assessment and monitoring of toxicants in the environment. Detailed chapters discussing the role of microbial biota, aquatic plants, terrestrial plants to enhance the accumulation efficiency of these toxic and heavy metals are followed by remediation techniques involving myco-remediation, bio-pesticides, bio-fertilizers, phyto-remediation and rhizo-filtration. A sizable portion of the book has been dedicated to the advanced bio-remediation techniques which are finding their way from the laboratory to the field for revival of the degraded ecosystems. These involve bio-films, micro-algae, genetically modified plants and filter feeders. Furthermore, the book is a detailed comprehensive account for the treatment technologies from unsustainable to sustainable. We believe academicians, researchers and students will find this book informative as a complete reference for biotechnological intervention for sustainable treatment of pollution.
