Covering key subjects and issues of well design, this second edition of Modern Well Design book sets out a systematic approach to improve the planning and design of wells, and suggests presentation of well design for easy verification and modification.

Sustainable Development has become the leading concept of the 21 century. It describes a development, which agrees with the needs of the present generation but does not endanger the chances of the coming generations to satisfy also their needs. "Sustainable development" has become an important general goal for all fields of life like economy, ecology and social balance. The development and shaping of our future has been discussed internationally like on the summits of the Conferences in Rio and in Johannesburg. But this is also a topic on national base in various countries. Leading authorities in various fields of economy and politics have also accepted this concept. Although the concept of sustainable development has been generally accepted, there are still problems how to achieve and evaluate these general goals. It is clear that the definitions about the prime needs vary from man to man, from country to country and from continent to continent. But pollution does not respect national borders. Therefore, it is necessary to develop the politics of economy, ecology and social demands by a synergistic way that they are strengthened by each other. If it is not possible to stop tendencies, which threaten the future quality of life, the cost demands of societies will dramatically increase and negative tendencies will become irreversible.

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.

Mineral scale deposits, corrosion, suspended matter, and microbiological growth are factors that must be controlled in industrial water systems. Research on understanding the mechanisms of these problems has attracted considerable attention in the past three decades as has progress concerning water treatment additives to ameliorate these concerns. The Science and Technology of Industrial Water Treatment provides a comprehensive discussion on the topic from specialists in industry and academia. The book begins with an overview of water chemistry and covers the characteristics of commonly encountered mineral scales. It addresses the formation and control of different scales in various systems and examines new developments in membrane-based separation processes. Next, it provides a detailed account on the operational challenges of reverse osmosis systems and scale control in thermal distillation processes. The text explores corrosion control in cooling, boiler, geothermal, and desalination systems and it discusses the interactions of polyelectrolytes with suspended matter. Includes coverage of a range of bacterial species, including Legionella The book examines bacterial species commonly encountered in water supplies, the mechanisms of biofouling, approaches to control it, and criteria for selecting biocides for water treatment applications. An entire chapter is devoted to Legionella in water systems. Contributors describe various analytical techniques for identifying mineral scales and deposits. They also examine applications of polymers for treating industrial and wastewater systems and give an account of analytical approaches for monitoring various operational parameters and chemicals used to treat industrial water systems. A valuable addition to the library of academic researchers, this volume will also prove useful to those working not only in the water treatment industry, but also to those in petroleum, textiles, pharmaceuticals, and other areas where purity processes are a significant concern.

No one has recorded when well digging started, but surely humans imitated elephants in digging holes in the sand to access cooler water that didn't make the children sick. Eventually, humankind began to redesign, maintain, and repair the wells they constructed, but when wells became "commodities" in the twentieth century, this maintenance ethic was fogotten. Recapturing that ethic, Sustainable Wells: Maintenance, Problem Prevention, and Rehabilitation is a guide to keeping well systems operating at peak capacity. The book focuses on how to prevent and forestall problems, and manage the problems with wells as they age. Examining the many challenges that come with maintaining well performance, the book provides a comprehensive yet readable state-of-the-art summary of performance maintenance, problem prevention, and rehabilitation or restoration practice with the goal of sustaining optimal performance over the long run. Rather than focusing on a certain aspect of well cleaning, or a particular technical approach, it covers the scope of maintenance and rehabilitation, from planning to evaluation testing. It also addresses the crucial subjects of preventive design, maintenance monitoring from electrical to biofouling, and evaluation testing. An exploration of the subject without a vendor or strong regional bias, the book is based on the authors' extensive hands-on experience serving well-operating clientele. In addition to water supply wells, it addresses the problems and maintenance issues of monitoring, plume control, and other "environmental" wells. Compiling information from existing literature into a single source, and combining that information with experience, the book provides recommendations based on historical performance. Copiously illustrated with approximately ninety black and white photographs, figures, and a color insert, the book reflects the changes in the profession that have occurred during the past decade or so. These features and more make this the first resource to turn to when devising solutions for maintaining and improving well performance.

Biofilms represent the natural living style of microbial communities and play a pivotal role in biogeochemical cycles and natural attenuation. Biofilms can be engineered for biodegradation and biotransformation of organic and inorganic contaminants, for both in situ bioremediation and ex situ treatment in bioreactors. This book focuses on microbial biofilms and their potential technological applications for sustainable development. It covers recent advances in biofilm technologies for contaminant remediation coupled to recovery of resources and serves as a complete reference on the science and technology behind biofilm mediated bioremediation and wastewater treatment.

The Ural river, the third longest river in Europe, is a unique ecosystem. Unlike other large European rivers the river has not been regulated and the natural hydrological regime is still intact. Thanks to that it has the only remaining spawning habitats in the entire Caspian basin for all sturgeon species. Nevertheless, this fact is not well known to the broader scientific and environmental communities.

The Ural river is also an interesting place due to its rich history of sustainable use of aquatic resources in general and sturgeons in particular. The traditional life style of the local communities, Ural Cossacks, was focused on the preservation and rational use of sturgeon species. This interesting experience of sustainable river-related management is not adequately reported in literature.

To secure further Ural sturgeon preservation the river basin ecosystem and human activities in the region must be managed in an integrated sustainable manner. The sturgeon species can be used as a natural indicator and an incentive for such transboundary IWRM cooperation taking into account all three components of sustainable development: economic, social and environmental. To secure basin IWRM and sturgeon stock restoration the International Ural Sturgeon Park should be established. The role of the Park will be to secure the natural reproduction in the Ural as the primary strategy for the sturgeon stock replenishment. The Ural River Basin Project, which aims at the creation of such a Park, was launched in 2007. This volume is devoted to the uniqueness, history and problems of the Ural river basin, its sturgeons and perspectives of their conservation.

This book presents the proceedings of the NATO Advanced Research Workshop Wastewater Reuse - Risk Assessment, Decision-Making and Environmental Security, held in Istanbul in October, 2006. The papers survey the current state of water management in the world and especially the Middle East and Mediterranean regions, and address some of the most difficult international conflicts. Wastewater, a by-product of agricultural, industrial or domestic water use, can be an environmental hazard causing damage to soil and to water resources. However, as demonstrated in many of the papers, it can also be a benefit if exploited correctly. Papers presented cover in great detail and depth the risk assessment, decision-making approaches and environmental security. Information about design, installation, management of wastewater treatment facilities, and use for saline water is provided by experts from the EU, UNESCO, World Bank, United States, Canada and other contributing agencies.

This book is based on the discussions and papers prepared for the NATO Advanced Research Workshop that took place under the auspices of the NATO Security Through Science Programme and addressed urban water management problems. The workshop sought to critically assess the existing knowledge on Xenobiotics in urban water cycle, with respect to diverse conditions in participating countries, and promote close co-operation among scientists with different professional experience.

The Central Asian republics and neighboring countries are currently experiencing problems related to the availability and efficient/equitable distribution of freshwater. This book contains papers from a NATO-sponsored Advanced Research Workshop that was organized to address these concerns. It addresses the myriad of issues involving shared freshwater among the countries in this region, discussing ecology, law, economics, politics, water policy and integrated water management.

In the contemporary West, pressures to more effectively reallocate water to meet growing urban and environmental demands are increasing as environmental awareness grows and climate change threatens existing water supplies.
The legacy of Owens Valley raises concerns about how reallocation can occur. Although it took place over seventy years ago, the water transfer from Owens Valley to Los Angeles still plays an important role in perceptions of how water markets work. The memory of Owens Valley transfer is one of theft and environmental destruction at the hands of Los Angeles. In reassessing the infamous transfer, one could say that there was no "theft." Owens Valley landowners fared well in their land and water sales, earning more than if they had stayed in agriculture. In another sense, however, "theft" did occur. The water was not literally stolen, but there was a sharp imbalance in gains from the trade--with most of the benefits going to Los Angeles. Owens Valley, then, demonstrates the importance of distributional issues in water trades when the stakes are large.
Los Angeles water rights in the Owens Valley and Mono Basin have again been a front-page issue since 1970. New environmental and recreational values and air pollution concerns have ushered in demands to curtail the shipment of water from source regions for urban use.
Owen's Valley Revisited: A Reassesment of the West's First Great Water Transfer carefully explores how these sagas were addressed, considering the costs involved, and alternative approaches that might have resulted in more rapid and less contentious remedies. This analysis offers insights to guide the ongoing conversation about water politics and thefuture thereof.

Water scarcity affects the African, Asian, European and American continents, causing serious problems of social welfare and stability. This book of the NATO Science Series presents the state of the art of Desalination Technologies driven by Renewable Energies, highlighting the results achieved in the research field and presenting the potentialities of such technologies. Following an Advanced Research Workshop held in Tunisia from the 23rd to the 25th of February 2006 and collecting prominent scientists from more than 20 different countries, several contributions were selected from researchers, technicians, and industrial representatives, each focused on several different aspects of the use of renewable energies for desalination. Moreover, several regional overviews illustrate the actual state of RE exploitation in most of the countries interested by water scarcity and abundant availability of solar, wind and other renewable energies.

In the contemporary West, pressures to more effectively reallocate water to meet growing urban and environmental demands are increasing as environmental awareness grows and climate change threatens existing water supplies.

The provision of safe drinking water is one of the primary responsibilities of all governments, which address and share this responsibility through various levels of administration, ranging from the municipal to federal level, and further sharing of such responsibilities with public or private water utility companies. Recent reviews indicate the existence of significant vulnerabilities of all components of the infrastructure in general, among which the water supply systems are considered the most critical because of it's importance to human life. Indeed, such systems encompas huge number of stuctures, plants and devices that might become a target of sabotage, and they all may be found in major components of each water supply system: the raw water sources (usually a reservoir, a river intake, or groundwater aquifer), water purification plants (encompassing various treatment processes), and water distribution networks bringing potable water to the consumers. Consequently, the reality of the post-September 11 situation forces the operators of water supply systems throught the world to examine the security and safety of their systems, it's vulnerability to intentional interference and sabotage with respect to quantity and quality of potable water. In assessing the system vulnerability, there is an urgent need to develop emergency response plans providing ways and means for alternative water supply for the moment of system operation disruption, and system remediation and recovery after the attack.

The objective of this book is to summarize and critically assess the current status, development trends and needs of three basic defensive elements that safeguard the quality and environmental safety of soil and water/sediments: early warning monitoring, protection and remediation measures, with particular regard to the viability of methods and technologies, i.e. easiness-to-use, reliability, cost-effectiveness, high efficiency and non-destructive character of remediation that is of particular importance considering the scale of application. The priority aim of the book is to contribute to the improving maintenance of ecosystems, and specifically to summarize and add to information on how best to protect our soils and aquifers, prevent migration and mobilization of pollutants and how to enhance their degradation and/or immobilization. Mechanism of action is considered of the first priority, but optimization of technical construction/application details are of no lesser importance. In the permeable reactive barriers, and other preventive/remediation measures, a number of novel integrated physicochemical and biochemical methods are presented. The remediation solutions for soil pollution are focused on non-destructive methods such as phyto- and ecoremediation that would preserve soil properties during and after decontamination. The contributors to the book are internationally recognized experts, which present both state-of-the art and novel approaches in the above fields that makes the book unique with respect to the scope.

Ever increasing urbanization is impacting both the quantity and quality of urban water resources. These urban water resources and components of the water cycle are likely to be affected severely. To minimize the consequences on world water resources, the development of sustainable water resources management strategies is inevitable. An integrated urban water resources management strategy is the key to maintain sustainable water resources. A preliminary understanding of physio-chemical processes and analysis methodologies involved in each and every component of the urban water cycle is necessary. In the past these components have been investigated and published individually. With the view to aiding the development of integrated urban water resources management strategies, this book endeavors to present and explain the major urban water cycle components from a single holistic platform. The book presents the introduction, analysis and design methods of a wide range of urban water components i.e., rainfall, flood, drainage, water supply and waste water with the additions of sustainability practices in most of the components. Current "Hydrology" and "Hydraulics" books do not incorporate sustainability features and practices, while there are many books on general "Sustainability" without integrating sustainability concepts into typical engineering designs. The book starts with components and classifications of world water resources, then basic and detailed components of the hydrologic cycle, climate change and its impacts on hydrologic cycle, rainfall patterns and measurements, rainfall losses, derivations of design rainfalls, streamflow measurements, flood frequency analysis and probabilistic flood estimations, deterministic flood estimations, unit hydrograph, flood modelling, commercial modelling tools and use of Geographical Information System (GIS) for flood modelling, principles of open channel hydraulics, critical flow and flow classification indices, open channel flow profiles, uniform flow in open channel and open channel design, estimation of future population and domestic water demand, design of water supply systems, sustainable water supply system, water treatments, wastewater quantification, wastewater treatments, sustainable and decentralized wastewater treatment, stormwater drainage and urban drainage analysis, water footprint and water-energy nexus, features of water conservation, harvesting and recycling, components of sustainable urban design, stormwater treatment and integrated water management.

Although microorganisms can be found virtually anywhere on our planet, from clouds to soils to oceans, they are often poorly understood when examining issues related to groundwater and water wells. Focusing on the impact of microorganisms on groundwater and water wells, Practical Manual of Groundwater Microbiology, Second Edition presents over 75% new material to offer a comprehensive, up-to-date guide on the subject. The first eight chapters provide an overview of microbiology and its importance in groundwaters, exploring natural filters that develop around wells, various bacteria, molds, viruses, sampling procedures, biofouling, biofilms, sequestration strategies, rehabilitation/regeneration practices, and flooding risks. The book also contains a chapter that functions as a self-contained guide, with 79 descriptive illustrations of important concepts integral to the understanding of microbes in groundwater. Numerous appendices, some new to this edition, supply detailed information on more specialized topics, such as microbiological test methods, water sample protocols, regulatory considerations concerning the use of phosphorus in wells, and the application of vegetable oil to lubricate pumps. Chronicling the significant progress made in the field since the publication of its predecessor, this edition provides practical approaches for evaluating the effects of microorganisms and their activities on groundwater and water wells.

Fully revised and updated, this second edition of Water Ethics continues to consolidate water ethics as a key dimension of water-related decisions. The book introduces the idea that ethics are an intrinsic dimension of any water policy, program, or practice, and that understanding what ethics are being acted out in water policies is fundamental to an understanding of water resource management. Alongside updated references and the introduction of discussion questions and recommended further reading, this new edition discusses in depth three significant developments since the publication of the first edition in 2013. The first is the growing awareness of the climate crisis as an existential threat, and associated concern about adaptive strategies for sustainable water management and ways of using water management for climate mitigation (e.g., practically through agricultural soil management and conceptually through ethics awareness). Second, there has been increased clarity among the religious community, Indigenous leaders, and progressive academics that ethics needs to become an arena for application and action (e.g., the Vatican encyclical Laudato Si, protests at Standing Rock and Flint, Michigan, in the US, and climate demonstrations worldwide). Thirdly, there have been new normative water standards ranging from "water stewardship" (industry initiative), water charters (Berlin) and the on-going initiative to develop a global water ethics charter. Drawing on case studies from countries including Australia, India, the Philippines, South Africa, and the United States, this textbook is essential reading for students of environmental ethics and water governance and management.

The Lake Governance book will focus on comparative analysis of governance structures by examining policy, legal and institutional structures of current transboundary commissions to develop a common framework for good governance of transboundary lakes. Cooperation among nations sharing natural resources is important for sustainable use of the shared resources. Lakes contribute a big part to GDP in most of the countries and in some cases are also responsible for providing fisheries (for food, source of protein and livelihood). Climate change and associated risks and uncertainties add more complexity to the problems. This book will explore current water governance challenges, knowledge gaps and recommend a framework for good lake governance.

As urban areas keep growing, water infrastructure ages, and the requirements on environmental protection become more rigorous, there is a continual need for upgrading water pollution control facilities and restoring degraded urban waters. Such issues are addressed in this book by focusing on five major topics: (a) Upgrading stormwater management facilities, (b) Retrofitting / upgrading combined sewer overflow (CSO) facilities, (c) Optimising/upgrading sewage treatment plant performance, (d) Urban stream restoration, and (e) Challenges in restoring urban environment. Each chapter contains some overview papers followed by research or case study papers. Besides presentations of new approaches and accomplishments in the field of upgrading and restoration, several papers provide analysis of vast needs in this field in several countries of Central and Eastern Europe, which either recently joined the European Union (EU) or are preparing for accession, and need to comply with the existing EU directives dealing with environmental protection. As such, this book will be of primary interest to researchers and university lecturers dealing with environmental upgrading and restoration, environmental planners from all levels of government, municipal engineers and politicians, and finally the private industry representatives (consultants, private utilities and environmental technology suppliers) searching for new business opportunities among the new or aspiring members of EU.

Urban population growth dramatically alters material and energy fluxes in the affected areas, with concomitant changes in landscape, altered fluxes of water, sediment, chemicals and pathogens and increased releases of waste heat. These changes then impact on urban ecosystems, including water resources and result in their degradation. Such circumstances make the provision of water services to urban populations even more challenging. Changing weather patterns, rising temperature and large variations in precipitation contr- ute to increased damages, caused by weather related disasters, including floods. Ones of the major contributors to increasing flood peaks are land use changes and particularl- urban development. Consequently, there is a need to look for low environmental impact land development and to manage runoff in urban areas by storm water management. Much progress in the management of urban waters has been achieved in the most - vanced jurisdictions, but much more remains to be done. In this respect the EC Water Framework Directive can provide some guidance. Urban water management issues are particularly important in the countries in transition in Central and Eastern Europe. During the last decade political, economical and social changes in the countries under transition have influenced almost every element of the public sector, including water services. There is an urgent need for exchange of information among various countries on this issue and for identification of best approaches to achieving this transition.

This book documents state of the art research designed to compliment the advances being made in the global water quality sector. Book 2 provides further detail on supporting programmes.

There is growing acceptance that the progress delivered under the Millennium Development Goal target for drinking water and sanitation has been inequitable. As a result, the progressive reduction of inequalities is now an explicit focus of the Sustainable Development Goal (SDG) targets, adopted in 2015, for universal access to drinking water, sanitation and hygiene (WASH). This shift in focus has implications for the way in which the next generation of WASH policies and programmes will be conceived, designed, financed and monitored. This book provides an authoritative textbook for students, as well as a point of reference for policy-makers and practitioners interested in reducing inequalities in access to WASH services. Four key areas are addressed: background to the human right to water and development goals; dimensions of inequality; case studies in delivering water and sanitation equitably; and monitoring progress in reducing inequality.

Life Cycle Assessment of Wastewater Treatment addresses in detail the required in-depth life cycle assessment of wastewater treatment. This is to meet the special demands placed upon wastewater treatment processes, due to both the limited quantity and often low quality of water supplies. Wastewater management clearly plays a central role in achieving future water security in a world where water stress is expected to increase. Life cycle assessment (LCA) can be used as a tool to evaluate the environmental impacts associated with wastewater treatment and potential improvement options. This unique volume will focus on the analysis of wastewater treatment plants (WWTPs), using a life cycle assessment (LCA) approach. Key Features: Focuses on the analysis of wastewater treatment plants using a life cycle assessment (LCA) approach Discusses unconventional water sources such as recycled wastewater, brackish groundwater and desalinated seawater Explains life cycle assessment in detail, which has become one of the reference methods used to assess the environmental performance of processes over their complete life cycle, from raw material extraction, infrastructure construction and operation to final dismantling Explores a technique (LCA) that is becoming increasingly popular amongst researchers in the water treatment field nowadays because of its holistic approach Based on the real life experiences, the subject of wastewater is presented in simple terms and made accessible to anyone willing to learn and experiment
