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

This book was released on 2003-11-06 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text prepared by an international group of experts addresses the 'heterotrophic plate count' test which is widely used in drinking-water assessment: what it detects (and what it does not detect) its direct and indirect health significance and its use in the safety management of drinking water supplies. It includes the consensus statement from an expert review meeting and takes account of the presentations and posters at an international conference on the theme co-sponsored by WHO and NSF-International. It provides valuable information on the utility and the limitations of HPC data in the management and operation of piped water systems as well as other means of providing drinking water to the public. It is of particular value to piped public water suppliers and bottled water suppliers manufacturers and users of water treatment and transmission equipment and inline treatment devices water engineers sanitary and clinical microbiologists and national and local public health officials and regulators of drinking water quality. ...The book will be of great value to the piped public water suppliers bottled water suppliers manufacturers users of water treatment and transmission equipment and online treatment device makers water supply engineers sanitary engineers clinical and water microbiologists national and local public health officials and regulators of drinking-water quality. - Indian Journal of Medical Research

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.
