Sewer systems fall into the category "out of sight, out of mind" - they seldom excite interest. But when things go wrong with the air in the sewer system, they go very wrong. Consequences can be dramatic and devastating: sewer workers killed instantly by poisonous gas when they lift a sewer lid, or entire suburban blocks levelled by explosions. This book describes the atmospheric dangers commonly found in the sewer system. It provides easily-understood explanations of the science behind the hazards, combined with real-life examples of when things went dramatically wrong.

This book provides a concise synthesis of how toxic chemical pollutants affect physiological processes in teleost fish. This Second Edition of the well-received Water Pollution and Fish Physiology has been completely updated, and chapters have been added on immunology and acid toxicity. The emphasis, as in the first edition, is on understanding mechanisms of sublethal effects on fish and their responses to these environmental stressors. The first chapter covers the basic principles involved in understanding how fish respond, in general, to environmental alterations. Each subsequent chapter is devoted to a particular organ system or physiological function and begins with a short overview of normal physiology of that system/function. This is followed by a review of how various toxic chemicals may alter normal conditions in fish. Chapters covering environmental hypoxia, behavior, cellular enzymes, and acid toxicity are also included. The book closes with a discussion on the practical application of physiological and biochemical measurements of fish in water pollution control in research and regulatory settings.

Agrochemicals and agricultural practices have a tremendous impact on environmental quality, particularly their role in water quality degradation. Soil Processes and Water Quality examines principles and practices that minimize the risks of water pollution while enhancing agricultural intensification and productivity. It focuses on how agricultural practices-such as tillage methods, use of fertilizers and manures, cropping systems, and the use of agrochemicals and pest control measures-impact soil processes and affect water quality. Extensive coverage of such topics as water contamination by runoff, leaching, macropore flow, and sediments is also included. Rapid increases in the use of agrochemicals make Soil Processes and Water Quality an indispensable reference for soil scientists, water quality professionals, researchers, environmental chemists, agrochemicals professionals, government agency employees, academic instructors, agronomists, and students.

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.

Hydrometry is concerned with the measurements of all the variables in the hydrological (water) cycle and hydrological information is therefore necessary for the practice of efficient water management. Water will be a major issue as the world enters the third millennium where more than one quarter of its population still do not have safe drinking water. An increasing demand is therefore placed on hydrometry to provide the essential hydrometric information in order that the world's water resources may be managed more efficiently. The aim of this second edition is to continue the success of the first edition by including new chapters on weather radar, remote sensing, groundwater and tree ring analysis, important in extending hydrometric records. Chapters of the first edition have been brought up to date as necessary in accordance with new technology and care has been taken to bridge the gap between past methods in hydrometry. The book therefore provides an invaluable guide to managers as well as field personnel who have operation and decision making roles in water management. Contents: Flow measurement; Instrumentation; Long river records; Precipitation measuring radar; Satellite remote sensing; Groundwater; Tree ring analysis; Transmission of hydrometric data by satellite; Maximizing the utility of river flow data; Hydrometric data processing; Uncertainties and Measuring up to water resources assessment.

Rural-Urban Water Struggles compiles diverse analyses of rural-urban water connections, discourses, identities and struggles evolving in the context of urbanization around the world. Departing from an understanding of urbanization as a process of constant making and remaking of multi-scalar territorial interactions that extend beyond traditional city boundaries and that deeply reconfigure rural-urban hydrosocial territories and interlinkages, the chapters demonstrate the need to reconsider and trouble the rural-urban dichotomy. The contributors scrutinize how existing approaches for securing urban water supply - ranging from water transfers to payments for ecosystem services - all rely on a myriad of techniques: they are produced by, and embedded in, specific institutional and legal arrangements, actor alliances, discourses, interests and technologies entwining local, regional and global scales. The different chapters show the need to better understand on-the-ground realities, taking account of inequalities in water access and control, as well as representation and cultural-political recognition among rural and urban subjects. Rural-Urban Water Struggles will be of great use to scholars of water governance and justice, environmental justice and political ecology. This book was originally published as a special issue of Water International.

Equipment used for the analysis of water is frequently insufficiently sensitive to be able to detect the low concentrations of organic and inorganic substances present in samples. Applying preconcentration to the sample prior to analysis means the results gained are more accurate and can be used to report trends more effectively. Each chapter of Preconcentration Techniques for Natural and Treated Waters discusses a different method of preconcentration and its application to the preconcentration of cations, anions, organic substances and organometallic compounds. Drawing together the recent world literature available on the subject, this book provides detailed discussion of the need for reducing detection limits in analytical chemistry and ways of achieving this aim. Throughout the book emphasis is laid on providing practical experimental detail, facilitating further development of procedures. Numerous tables present information clearly and accessibly. This book will be an invaluable reference for biologists, chemists, agriculturists, toxicologists, oceanographers, and environmentalists dealing with the analysis of water in industry and academia.
