Available in PDF, EPUB and Kindle. Book excerpt: Health hazards vary greatly with different waters and their uses as well as with geography, climate, populations and their living standards. Only by defining practicable water quality objectives and priorities in the light of current knowledge and likely cost benefit can the risks of actual and potential disease be reduced to acceptable levels. These, however, will still vary in different parts of the world. Universal standards, in contrast to objectives, are still a long way ahead. In this paper, the British approach to the choice and use of bacterial indicator organisms in relation to potential health hazards and water quality criteria is reviewed briefly. Although no mandatory standards have ever been imposed, drinking water supplies in Britain are among the best in the world in quality and safety, even though about two thirds of them are derived directly from sewage polluted surface waters. However polluted these may be, in principle, they can be adequately treated, and British philosophy has always relied on this rather than on the more elusive targets of disinfecting sewage effluents and purifying water sources. For almost 50 years, coliform organisms and Escherichia coli have been used as the main indicators of fecal pollution, and, in this way, the efficiency of treatment and thus the safety of drinking water supplies have been effectively monitored. Despite increased water usage and recycling, there is no valid reason to change this view. Although viruses can be isolated readily from sewage effluents, there is no epidemiological evidence of transmission to man by the water route, and the current position is one of surveillance and research. Similarly, despite intensive investigation, there is no authenticated evidence of significant disease attributed to sewage polluted bathing beaches or efficiently maintained swimming pools. Aesthetic values, however, are now playing a greater role in environmental pollution control. In addition, compliance with microbiological and other standards for water for abstraction as well as for bathing recently accepted by the European Economic Community will be necessary in the future.

This book was released on 2004-06-19 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â

Available in PDF, EPUB and Kindle. Book excerpt: "Access to safe water is a fundamental human need and therefore a basic human right" --Kofi Annan, United Nations Secretary General Edited by two world-renowned scientists in the field, The Handbook of Water and Wastewater Microbiology provides a definitive and comprehensive coverage of water and wastewater microbiology. With contributions from experts from around the world, this book gives a global perspective on the important issues faced in the provision of safe drinking water, the problems of dealing with aquatic pollution and the processes involved in wastewater management. Starting with an introductory chapter of basic microbiological principles, The Handbook of Water and Wastewater Microbiology develops these principles further, ensuring that this is the essential text for process engineers with little microbiological experience and specialist microbiologists alike. Comprehensive selection of reviews dealing with drinking water and aquatic pollution Provides an understading of basic microbiology and how it is applied to engineering process solutions Suitable for all levels of knowledge in microbiology -from those with no background to specialists who require the depth of information

Download or read book Bacterial Water Quality and Standards written by MJ. Suess and published by . This book was released on 1977 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the tasks of the World Health Organization (WHO) is the development of environmental health criteria. In this connection, it has been concerned with some problems related to the concept of indicator bacteria and the rapid and reliable identification of pathogenic ones. WHO requires the absence of any organisms of fecal origin in drinking water and refers to Escherichia coli, fecal streptococci, and Clostridium perfringens as the most representative of fecal pollution. Potable water supplies for aviation and shipping have to be of similar quality. To assist in the control of surface water pollution, a manual, which includes a chapter on bacteriological examination, has been prepared to encourage the use of approved analytical methods. Attention has also been given to the survey and examination of recreational and shellfish-bed waters.

Download or read book Water Quality written by Lorna Fewtrell and published by World Health Organization. This book was released on 2001-09-30 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential to increase consistency in approaches to assessment and management of water-related microbial hazards was tackled by an international group of experts concerned with drinking water, irrigation and wastewater use and recreational/bathing water. It included individuals with expertise in public health, epidemiology, risk assessment, risk management, standards and regulation, communication and economics. Subsequently, a series of reviews was progressively developed and refined, which addressed the principal issues of concern linking water and health to the establishment of implemenation of effective, affordable and efficient guidelines and standards. This book is based on these reviews, together with the discussions of the harmonized framework that was proposed to improve consistency between guidelines and the issues surrounding it.; This book should prove useful to all those concerned with issues relating to microbial water quality and health, including environmental and public health scientists, water scientists, policy makers and regulators.

Available in PDF, EPUB and Kindle. Book excerpt: We have identified a need to draw together knowledge of physiochemical and biological aspects of pollution in tropical aquatic systems. This book results from this and we hope will assist in providing management strategies to protect these systems from pollution effects. In organising the book we have, as far as possible, attempted to cover the range of topics important in understanding pollution in tropical areas. Authors who are expert in their particular fields have been invited to contribute. We recognise that many topics remain uncovered but we hope will serve to assist in identifying these and stimulate interest in this area.
