Originally published in 1991, this study uses the 1983 outbreak of Giardiasis in Luzerne County, Pennsylvania as a case study to explore the social costs of waterborne illnesses to a community. With over 6,000 people affected in that particular case, Economics and Episodic Disease emphasises the importance of Federal and State drinking water standards to protect the population from contamination whilst also commenting how regulations can be applied to other areas within public health as well as how to appraise the damage caused to surface water by the release of hazardous substances. This title will be of interest to students of Environmental Studies.

The interest in finding reliable and highly sensitive sensors for water quality control has grown recently empowered by the explosion of cutting-edge technologies such as nanotechnologies, optoelectronics, and computing on one hand and by the increasing need for more secure control of water quality on the other hand. This book highlights a number of modern topics in the field of biosensing particularly for water sensing in which the signal is enhanced, starting from surface enhanced spectroscopies using plasmonic structures such as Raman scattering (SERS), infrared enhanced absorption (SEIRA), and surface enhanced fluorescence (SEF). The SPR enhanced detection is highlighted in two chapters and addressed using signal processing and the use of color of solutions as a result of modification of the LSPR properties of nanoparticles. Porous materials are another field of research where the enhancement is achieved due to the increasing the area- to-volume ratio. Good examples are the two emerging fields of porous Si and sculptured thin films prepared by the oblique deposition technique. One of the long standing problems is bacteria detection in water which is addressed thoroughly with emphasis on the problems usually encountered in detecting large bioentities.

This title, first published in 1987, examines the topic of nuclear waste management, and the way in which the public reacts to this issue.

Public agencies and industry will probably spend tens of billions of dollars on new water pollution abatement facilities in the next few decades. Added billions will be spent for the operation of new and existing facilities. How can physical science research reduce the cost of achieving objectives? And how can social science research make sure that the right objectives are being efficiently pursued? This title, first published in 1962, is directed to the orientation of the research effort, and the tool used for this purpose is an economic framework. This book will be of interest to students of economics and environmental studies.

Modern Irrigation Technologies reviews the experience of small holders with irrigation technologies under a range of diverse conditions in many different countries. Some people argue that modern irrigation technologies are the key to increased food production. However, projects introducing modern irrigation technologies in the developing world have often failed because the irrigation hardware, which has been developed for high-technology commercial agriculture, cannot be easily adapted for the use of the smallholder. The author identifies the pre-conditions relating to water availability, institutional support and economic opportunity that must be satisfied before small holders in developing countries can adopt irrigation methods and benefit from them. The circumstances in which modern technologies have been introduced are identified, and the relative success or otherwise of the initiatives are summarized. The book also contains a practical review of the range of irrigation hardware that is available and indicates the types of equipment that are more likely to meet the requirements of the smallholder sector. Modern Irrigation Technologies will be an invaluable guide to project workers, planners and small holders involved in planning and designing irrigation projects.

The world's freshwater supplies are increasingly threatened by rapidly increasing demand and the impacts of global climate change, but current approaches to transboundary water management are unsustainable and may threaten future global stability and international security. The absence of law in attempts to address this issue highlights the necessity for further understanding from the legal perspective. This book provides a fresh conceptualisation of water security, developing an operational methodology for identifying the four core elements of water security which must be addressed by international law: availability; access; adaptability; and ambit. The analysis of the legal framework of transboundary freshwater management based on this contemporary understanding of water security reveals the challenges and shortcomings of the current legal regime. In order to address these shortcomings, the present mindset of prevailing rigidity and state-centrism is challenged by examining how international legal instruments could be crafted to advance a more flexible and common approach towards transboundary water interaction. The concept of considering water security as a matter of 'regional common concern' is introduced to help international law play a more prominent role in addressing the challenges of global water insecurity. Ways for implementing such an approach are proposed and analysed by looking at international hydropolitics in Himalayan Asia. The book analyses transboundary water interaction as a 'case study' for advancing public international law in order to fulfil its responsibility of promoting international peace and security.

London's sewers could be called the city's forgotten underground: mostly unseen subterranean spaces that are of absolutely vital importance, the capital's sewers nonetheless rarely get the same degree of attention as the Tube. Paul Dobraszczyk here outlines the fascinating history of London's sewers from the nineteenth century onwards, using a rich variety of colour illustrations, photographs and newspaper engravings to show their development from medieval spaces to the complex, citywide network, largely constructed in the 1860s, that is still in place today. This book explores London's sewers in history, fiction and film, including how they entice intrepid explorers into their depths, from the Victorian period to the present day.

This book is divided into seven chapters, which address various leachate landfill management issues such as the quality, quantity and management of municipal landfill leachate, together with new methods. There are many methods available for the treatment and management of municipal landfill leachate. The waste management methods presented here can be applied in most third-world countries, due to the lack of waste separation and high organic content of waste. The book provides descriptions and a hierarchy of waste management, reviews the history of solid waste disposal, and covers a range of topics, including: leachate and gas generation in landfills; natural attenuation landfills; landfill site selection; leachate and stormwater management, collection and treatment; landfill gas management; landfill cover requirements; leachate collection; types of natural treatment systems; and design procedure and considerations. In closing, it provides an overview of the current solid waste management status in Iran.

Singapores journey during the past 45 years is an outstanding example that, in spite of multiple hardships, pragmatic policies, clear visions, long-term planning, forward-looking strategies and political will, as well as a relentless urge to improve, can result in strong foundations for sustainable development. This book describes the journey of Singapores development and the fundamental role that water has had in shaping it. What makes this case so unique is that the quest for self-sufficiency in terms of water availability in a fast-changing urban context has been crucial to the way development policies and agendas have been planned throughout the years. The authors analyse plans, policies, institutions, laws and regulations, water demand and water supply strategies, water quality and water conservation considerations, partnerships and importance of the media. They assess overall how all these issues have evolved in response to the dynamic needs of the city-state. The study of Singapore shows how a dynamic society can address development without losing its focus on the environment. In the city-state, environmental concerns in general, and water concerns in particular, have played a major role in its transformation from a third word to a first world country. How and why this transformation took place is the main focus of this authoritative book.

Urban sanitation and solid waste sectors are under significant pressure in East Africa due to the lack of competent institutional capacity and the growth of the region's urban population. This book presents and applies an original analytical approach to assess the existing socio-technical mixtures of waste and sanitation systems and to ensure wider access, increase flexibility and ecological sustainability. It shows how the problem is not the current diversity in waste and sanitation infrastructures and services and variety of types and scales of technology, of formal and informal sector involvement, and of management and ownership modes. The book focuses instead on the lack of an integrative approach to managing and upgrading of the various waste and sanitation configurations and services so as to ensure wider access, flexibility and sustainability for the low income populations who happen to be the main stakeholders. This approach, coined "Modernized Mixtures", serves as a nexus throughout the book. The empirical core addresses the waste and sanitation challenges and debates at each scale - from the micro-level (households) to the macro-level (international support) - and is based on the results of a five-year-long interdisciplinary, empirical research program. It assesses the socio-technical diversity in waste and sanitation and provides viable solutions to sanitation and waste management in East Africa. This book provides students, researchers and professional in environmental technology, sociology, management and urban planning with an integrated analytical perspective on centralized and decentralized waste and sanitation configurations and tools for improvement in the technology, policy and management of sanitation and solid waste sectors.

The purpose of this book is to present an overview of the latest research, policy, practitioner, academic and international thinking on water security-an issue that, like water governance a few years ago, has developed much policy awareness and momentum with a wide range of stakeholders. As a concept it is open to multiple interpretations, and the authors here set out the various approaches to the topic from different perspectives. Key themes addressed include: Water security as a foreign policy issue The interconnected variables of water, food, and human security Dimensions other than military and international relations concerns around water security Water security theory and methods, tools and audits. The book is loosely based on a masters level degree plus a short professional course on water security both given at the University of East Anglia, delivered by international authorities on their subjects. It should serve as an introductory textbook as well as be of value to professionals, NGOs, and policy-makers.

Our rivers and lakes are continuously self-purifying thanks to algal and bacterial biofilms that grow over the surface of stones and other debris. This same process has been employed for over a century to treat our municipal and industrial wastewater in specially designed fixed film reactors that maximize this microbial activity by providing ideal growth conditions and unlimited food and oxygen. Fixed film, or attached biofilm, reactors are unique in their ability to treat complex wastewaters and shock loadings; using far less energy than other wastewater treatment processes such as activated sludge, making them a sustainable treatment option.Targeted at undergraduate and postgraduate engineers and scientists, this book follows the structure of bestseller Biology of Wastewater Treatment. This volume gives an expanded and up-to-date overview of the use of fixed-film reactors in wastewater treatment with content spanning from biofilm formation, to traditional trickling filters and rotating biological contactor technology, advanced submerged systems (including MBBRs and IFAS) and their key role in the treatment of contaminated air, and finally to nitrogen removal employing new microbial pathways such as Anammox. This monograph emphasizes the biological aspects of the processes.

Appropriate for courses in Water Resources, Groundwater and Wastewater The new seventh edition of Water and Wastewater Technology continues its tradition of coverage water processing principles and modern management practices, but now integrates a new emphasis on sustainability throughout. Comprehensive coverage of topics such as: * Water processing * Water distribution * Wastewater collection * Conventional and advanced wastewater treatment * Sludge processing.

In an increasingly global community of researchers and practitioners, new technologies and communication means have made the transfer of policies from one country or region to another progressively more prevalent. There has been a lot of attention in the field of public administration paid to policy transfer and institutional transplantation. This book aims to create a better understanding of such transfers in the water management sector. These include the adoption of modern water management concepts, such as integrated water resources management and forms of water governance, which are strongly promoted and sometimes also imposed by various international organizations. Transfers also occur within the scope of development aid or for the purpose of creating business opportunities. In addition, many research organisations, consultancies and governmental agencies are involved in cross-border work. The purpose of this book is therefore to present practical examples of the transfer of modern water management from one locality to another and to critically discuss the transferability of policy and governance concepts by analysing the contextual needs and factors. Case studies are included from North America, Europe, the Middle East and Asia. It is argued that in many cases context matters in water management and that there is no panacea or universal concept that can be applied to all countries or regions with different political, economic, cultural and technological contexts. Yet it is also shown that some countries are facing pressing and similar water management issues that cut across national borders, and hence the transfer of knowledge may be beneficial.

The litany of alarming observations about water use and misuse is now familiar-over a billion people without access to safe drinking water; almost every major river dammed and diverted; increasing conflicts over the delivery of water in urban areas; continuing threats to water quality from agricultural inputs and industrial wastes; and the increasing variability of climate, including threats of severe droughts and flooding across locales and regions. These issues present tremendous challenges for water governance. This book focuses on three major concepts and approaches that have gained currency in policy and governance circles, both globally and regionally-scarcity and crisis, marketization and privatization, and participation. It provides a historical and contextual overview of each of these ideas as they have emerged in global and regional policy and governance circles and pairs these with in-depth case studies that examine manifestations and contestations of water governance internationally. The book interrogates ideas of water crisis and scarcity in the context of bio-physical, political, social and environmental landscapes to better understand how ideas and practices linked to scarcity and crisis take hold, and become entrenched in policy and practice. The book also investigates ideas of marketization and privatization, increasingly prominent features of water governance throughout the global South, with particular attention to the varied implementation and effects of these governance practices. The final section of the volume analyzes participatory water governance, querying the disconnects between global discourses and local realities, particularly as they intersect with the other themes of interest to the volume. Promoting a view of changing water governance that links across these themes and in relation to contemporary realities, the book is invaluable for students, researchers, advocates, and policy makers interested in water governance challenges facing the developing world.

Contamination of water supplies and the immediate availability of appropriate emergency responses to chemical, biological, radiological or nuclear (CBRN) events which result in contaminated water are becoming increasingly relevant and significant issues in the water industry and in the wider world. Consequently, new strategies and technologies are being constantly evolved and refined by leading experts in the field in order to achieve rapid and effective responses to water contamination events. Water Contamination Emergencies: Enhancing our Response brings together contributions from leading scientists and experts from both academia and industry in the field of water contamination and emergency planning. The book covers a wide range of topics including responses to water contamination emergencies, impacts on public health and commerce, risk assessment, analysis and monitoring, emergency planning, control and planning and threats to the water industry. This book is ideal for specialists in the field of water contamination and emergency response planning, especially researchers and professionals in industry and government who require an authoritative and highly specialised resource on water contamination management. The reader will gain an appreciation of the activities supporting the development of responses to contamination events; emergency actions required in response to the contamination of drinking water; and incident management. Also discussed are the importance of communication between organisations and the public; consumer perceptions and the need for robust and rapid screening of samples taken in response to potential contamination events in order to help answer the key question "Is this water safe to drink?"
