Water is a finite resource, and the demand for clean water is constantly growing. Clean freshwater is needed to meet irrigation demands for agriculture, for consumption, and for industrial uses. The world produces billions of tons of wastewater every year. This volume looks at a multitude of ways to capture, treat, and reuse wastewater and how to effectively manage watersheds. It presents a selection of new technologies and methods to recycle, reclaim, and reuse water for agricultural, industrial, and environmental purposes. The editor states that more than 75-80% of the wastewater we produce goes back to nature without being properly treated, leading to pollution and all sorts of negative health and productivity consequences. Topics cover a wide selection of research, including molluscs as a tool for river health assessment, flood risk modeling, biological removal of toxins from groundwater, saline water intrusion into coastal areas, urban drainage simulations, rainwater harvesting, irrigation topics, and more. Key features: * explores the existing methodologies in the field of reuse of wastewater * looks at different approaches in integrated water resources management * examines the issues of groundwater management and development * discusses saline water intrusion in coastal areas * presents various watershed management approaches * includes case studies and analyses of various water management efforts

Key features: Takes a quantitative approach to the science of aquaculture Covers the complete landscape of the scientific basis of fish culture Promotes problem solving and critical thinking Includes sample problems at the end of most chapters Guides the reader through the technical considerations of intensive aquaculture, including fish growth rates, hydraulic characteristics of fish rearing units, oxygen consumption rates in relation to oxygen solubility and fish tolerance of hypoxia, and water reconditioning by reaeration and ammonia filtration. Discusses the environmental effects of aquaculture Includes a chapter on hatchery effluent control to meet receiving water discharge criteria Aquaculture Technology: Flowing Water and Static Water Fish Culture is the first book to provide the skills to raise fish in both a flowing water and a static water aquaculture system with a pragmatic and quantitative approach. Following in the tradition of the author's highly praised book, Flowing Water Fish Culture, this work will stand out as one that makes the reader understand the theory of each type of aquaculture system; it will teach the user "how to think" rather than "what to think" about these systems. The book presents the scientific basis for the controlled husbandry of fish, whether it be in a stream of water or a standing water pool. Part 1, Flowing Water Fish Culture, is a major revision of the author's initial book and includes greatly expanded coverage of rearing unit design criteria, fish growth and the use of liquid oxygen, hatchery effluent control, and recirculating systems. Part 2, Static Water Fish Culture, presents the scientific basis of fish culture in standing water systems including nutrient and dissolved gas dynamics, pond ecology, effects of fertilization and supplemental feeding, water quality management and representative static water aquacultures. Aquaculture Technology conveys the science in a manner appropriate for use by university students and teachers and others involved in fish production and aquaculture research and development worldwide. It will enable the reader to adapt to changing technologies, markets, and environmental regulations as they occur.

This time-saving book provides extensive coverage of all important aspects of nitrates in groundwater, ranging from prevention to problem assessment to remediation. It begins by highlighting the nitrogen cycle and related health concerns, providing both background information and a unique perspective on health issues. It then analyzes subsurface pr

Lessons can be learnt from the past; from time to time it is useful for practitioners to look back over the historical developments of their science. Hydrogeology has developed from humble beginnings into the broad church of investigatory procedures which collectively form the modern-day hydrogeologist's tool box. Hydrogeology remains a branch of the over-arching science of geology and today provides analysis of the sub-surface part of the water cycle within a holistic approach to problem solving. The History of Hydrogeology, is a first attempt to bring the story of the evolution of the science of hydrogeology together from a country- or region-specific viewpoint. It does not cover history to the present day, nor does it deal with all countries involved in groundwater studies, but rather takes the story for specific key countries up and until about the period 1975 to 1980. This is when hydrogeology was still evolving and developing, and in some areas doing so quite rapidly. The book has been written not only for practitioners of hydrogeology and hydrology but also for teachers and students to see the context of the evolution of the science around the globe. The History of Hydrogeology will also be of interest to science historians and all those interested in the role that individuals, institutes and nations have played over the years in defining modern day studies of groundwater.

This volume provides readers with an opportunity to learn from front line water managers of watershed-based agencies across Canada about integrated water management (or integrated water resource management). In common with practice in much of the world, the responsibility for implementing integrated watershed management in Canada is fragmented. Each province and territory in Canada has developed unique approaches or governance models to guide decision making in that regard. Thus, this edited volume enables readers from around the world to gain insight on the best practices in Canada for achieving success and addressing barriers to implement IWM. Although there remains non consensus about how to "best" approach river basin management, some of the main observations include: There is a need to balance a focus on "the big picture", with scoping the scale and scope of planning activities in order that feasible and effective solutions can be implemented Three types of integration are popular among the agencies included in the book: (i) among environment, economy and society, (ii) interactions between people and the environment and (iii) integration (or coordination) of administrative activities. Much more attention is required to achieving effective engagement from Indigenous communities The chapters were originally published in a special issue of the International Journal of Water Resources Development.

This book will address the major subsoil physical and chemical constraints and their implications to crop production; Plant growth is often restricted by adverse physical and chemical properties of subsoils yet these limitations are not revealed by testing surface soils and hence their significance in crop management is often overlooked. The major constraints can be physical or chemical. Physical limitations such as poor/nil subsoil structure, sandy subsoils that do not provide adequate water or gravelly subsoils and, etc. On the other hand, chemical constraints include acidity/alkalinity, high extractable Al or Mn, low nutrient availability, salts, boron toxicity and pyritic subsoils. Some of these constraints are inherent properties of the soil profile while others are induced by crop and soil management practices. This aim of this book is to define the constraints and discuss amelioration practices and benefits for crop production. This book will be of interest to readers involved with agriculture and soil sciences in laboratory, applied or classroom settings.

Mathematical models are the effective tool to solve different tasks predicting pollutant movement. The finite difference method is the oldest, but still remains widely used in hydrogeological practice. However, this method is not very useful to construct the new transport models because it cannot approximate the shape of remediation elements exactly. Therefore the book is concerned with the FEM (Finite Element Method) and BEM (Boundary Element Method), and also with the comparison of advantages of these methods in groundwater hydrology. The combination of the BEM and the random-walk particle tracking method, which seems to be a very useful tool to model the spread of pollution in groundwater, are also presented. The computer programmes have been developed on the basis of the theoretical backgrounds of these methods. They use the Visual C++ programming language for Windows 95/NT platform and will be included in the book.

The development of biofilms and their role in public health - particularly drinking water - is often overlooked. Ideal for anyone interested in water related issues, Microbiological Aspects of Biofilms and Drinking Water presents an overview of the public health effects associated with drinking water. It highlights the microbiological aspects relating to the development of biofilms. The first four chapters focus on the state of the water supply. The authors review methods for studying the epidemiological spread of waterborne infections and those used in surveillance and control of pathogenic microbes. He includes the methods used for the detection of pathogens of public health importance in drinking water. In the subsequent chapters the authors pay close attention to biofilm development within drinking water systems, underlining the public health threat. They cover the microbes important to public health and include the methods used to detect biofilms. In conclusion they review the methods involved in biofilm control - both conventional and biocidal treatments. Overall, Microbiological Aspects of Biofilms and Drinking Water provides a snapshot of public health and the water supply. It covers the future of drinking water and its associated health hazards and provides a deeper understanding of biofilms and how they provide a safe haven for pathogens and water related diseases.

Dealing with stormwater runoff in urban areas is a problem that is getting bigger and more expensive. As we cover porous surfaces with impervious structures-commercial buildings, parking lots, roads, and houses-finding places for rainwater and snowmelt to soak in becomes harder. Many landscapers, architects, planners, and others have proposed that the use of "green" localized management practices, such as rain gardens and bio-swales, may function as well as traditional "gray" pipes and basins at reducing the effects of stormwater runoff, and do so in a way that is more attractive in the landscape-and possibly also less expensive. To make stormwater management practices work, however, communities need to know the real costs and policy makers need to give people incentives to adopt the best practices. Economic Incentives for Stormwater Control addresses the true costs and benefits of stormwater management practices (SMPs) and examines the incentives that can be used to encourage their adoption. Highlighting the economic aspects, this practical book offers case studies of the application of various stormwater runoff control policies. It also presents the theory behind the different mechanisms used and illustrates successes and potential obstacles to implementation. The book covers: Efficient use of "green" SMPs Low-impact development (LID) style new construction Green infrastructure Property prices and incentive mechanisms to encourage homeowners to retain stormwater on their property Legal, economic, and hydrological issues associated with various incentive mechanisms In-lieu fees and cap-and-trade incentives Primarily concerned with the sociodemographic and economic aspects of people's participation in stormwater runoff control, this accessi

In the past decade there has been a rapid increase in waterborne outbreaks of disease associated with viral and protozoan agents, normally in drinking waters that were found to be microbially safe using the Coliform Index. For nearly a quarter of a century indicator organisms, in particular the coliform group, have been used to ensure the microbial quality of drinking water. Currently, world wide legislation to protect consumers is based on these outdated and unreliable tests and while there is considerable concern among scientists over their use, the water industry and regulators continue to place near total reliance on the Coliform Index. This book provides: * the first full account of the nature and applications of the Coliform Index * coverage of new and proposed water quality legislation: * details of emerging pathogens in water: * an evaluation of the role of the "coliform count" in future water quality analysis. It will be an essential tool for water companies at all levels, microbiologists, environmental health inspectors, environmental scientists and water engineers in industry whether working in developed countries or developing countries. Postgraduate students specialising in microbiology, civil and environmental engineering, environmental sciences and environmental health will find it a useful reference work as will undergraduates in these disciplines.

Vadose Zone Hydrology describes the elements of the physical processes most often encountered by hydrogeologists and ground-water engineers in their vadose zone projects. It illustrates the application of soil physics to practical problems relevant to the characterization and monitoring of the vadose zone. It includes an introduction to physical processes, including basic flow theory, and provides examples of important field-scale processes that must be recognizable by hydrogeologists. Considerable attention is given to the concepts of recharge, including how it is most accurately evaluated in the vadose zone. Field and laboratory methods for characterizing hydraulic properties in the vadose zone are also covered, and case studies illustrating these methods are provided. New and emerging technologies for monitoring the vadose zone, particularly for the purpose of detecting contaminants, are highlighted. In the last section of the book, additional case studies are presented, demonstrating applications related to seepage detection, landfill monitoring, and soil gas investigations. This book is written from the perspective of hydrogeologists and is designed to be directly applicable and to maintain continuity and consistency between chapters. It will be an invaluable primer for environmental or geotechnical consultants, regulators, or students who have no prior formal academic training in unsaturated flow concepts. Because the text contains some of the latest advances in this field, it will be an excellent reference for geologists and engineers currently working on problems of vadose zone hydrology.

Construction and management guidelines are clearly explained, providing information on applicable policies and regulations, siting and construction, and operations and monitoring of constructed wetlands treatment systems. Recent theoretical and empirical results from operating systems and research facilities, including such new applications as nutrient removal from eutrophic lakes and urban stormwater treatment within highway rights-of-way, are included. This book is an ideal resource for wastewater treatment plants, consulting engineers, federal and state regulators, industrial environmental managers, municipalities, environmental health professionals, and ecologists.

This new book focuses on sampling and analysis, radon and radium in water supply wells, predictive models, geologic and hydrogeologic controls that influence radon occurrence, monitoring radon and other radioactivity from geologic sources and mining impacts on occurrence of radioactivity in ground water. Also discussed are occurrence, testing, treatment, and reduction of radon from groundwater. Because the most severe health hazard from indoor radioactivity results from inhalation of short-lived radioactive decay products of radon, the EPA scheduled a major conference early in 1987 on Radon, Radium, and Other Radioactivity in Ground Water-Hydrogeologic Impact and Application to Indoor Airborne Contamination. The result is this book.

This book introduces the concept of Water Diplomacy as a principled and pragmatic approach to problem-driven interdisciplinary collaboration, which has been developed as a response to pressing contemporary water challenges arising from the coupling of natural and human systems. The findings of the book are the result of a decade-long interdisciplinary experiment in conceiving, developing, and implementing an interdisciplinary graduate program on Water Diplomacy at Tufts University, USA. This has led to the development of the Water Diplomacy Framework, a shared framework for understanding, diagnosing, and communicating about complex water issues across disciplinary boundaries. This framework clarifies important distinctions between water systems - simple, complicated, or complex - and the attributes that these distinctions imply for how these problems can be addressed. In this book, the focus is on complex water issues and how they require a problem-driven rather than a theory-driven approach to interdisciplinary collaboration. Moreover, it is argued that conception of interdisciplinarity needs to go beyond collaboration among experts, because complex water problems demand inclusive stakeholder engagement, such as in fact-value deliberation, joint fact finding, collective decision making, and adaptive management. Water professionals working in such environments need to operate with both principles and pragmatism in order to achieve actionable, sustainable, and equitable outcomes. This book explores these ideas in more detail and demonstrates their efficacy through a diverse range of case studies. Reflections on the program are also included, from conceptualization through implementation and evaluation. This book offers critical lessons and case studies for researchers and practitioners working on complex water issues as well as important lessons for those looking to initiate, implement, or evaluate interdisciplinary programs to address other complex problems in any setting.
