Book Synopsis Identifying Future Drinking Water Contaminants by : National Research Council
Download or read book Identifying Future Drinking Water Contaminants written by National Research Council and published by National Academies Press. This book was released on 1999-09-30 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an increasing population, use of new and diverse chemicals that can enter the water supply, and emergence of new microbial pathogens, the U.S. federal government is faced with a regulatory dilemma: Where should it focus its attention and limited resources to ensure safe drinking water supplies for the future? Identifying Future Drinking Water Contaminants is based on a 1998 workshop on emerging drinking water contaminants. It includes a dozen papers that were presented on new and emerging microbiological and chemical drinking water contaminants, associated analytical and water treatment methods for their detection and removal, and existing and proposed environmental databases to assist in their proactive identification and regulation. The papers are preceded by a conceptual approach and related recommendations to EPA for the periodic creation of future Drinking Water Contaminant Candidate Lists (CCLsâ€"produced every five yearsâ€"include currently unregulated chemical and microbiological substances that are known or anticipated to occur in public water systems and that may pose health risks).

This book was released on 2007-01-22 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

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
Book Synopsis WHO Housing and Health Guidelines by :
Download or read book WHO Housing and Health Guidelines written by and published by . This book was released on 2018 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improved housing conditions can save lives, prevent disease, increase quality of life, reduce poverty, and help mitigate climate change. Housing is becoming increasingly important to health in light of urban growth, ageing populations and climate change. The WHO Housing and health guidelines bring together the most recent evidence to provide practical recommendations to reduce the health burden due to unsafe and substandard housing. Based on newly commissioned systematic reviews, the guidelines provide recommendations relevant to inadequate living space (crowding), low and high indoor temperatures, injury hazards in the home, and accessibility of housing for people with functional impairments. In addition, the guidelines identify and summarize existing WHO guidelines and recommendations related to housing, with respect to water quality, air quality, neighbourhood noise, asbestos, lead, tobacco smoke and radon. The guidelines take a comprehensive, intersectoral perspective on the issue of housing and health and highlight co-benefits of interventions addressing several risk factors at the same time. The WHO Housing and health guidelines aim at informing housing policies and regulations at the national, regional and local level and are further relevant in the daily activities of implementing actors who are directly involved in the construction, maintenance and demolition of housing in ways that influence human health and safety. The guidelines therefore emphasize the importance of collaboration between the health and other sectors and joint efforts across all government levels to promote healthy housing. The guidelines' implementation at country-level will in particular contribute to the achievement of the Sustainable Development Goals on health (SDG 3) and sustainable cities (SDG 11). WHO will support Member States in adapting the guidelines to national contexts and priorities to ensure safe and healthy housing for all.

Book Synopsis Drinking Water Microbiology by : Gordon A. McFeters
Download or read book Drinking Water Microbiology written by Gordon A. McFeters and published by Springer Science & Business Media. This book was released on 2013-03-07 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microbiology of drinking water remains an important worldwide concern despite modem progress in science and engineering. Countries that are more technologically advanced have experienced a significant reduction in water borne morbidity within the last 100 years: This reduction has been achieved through the application of effective technologies for the treatment, disinfec tion, and distribution of potable water. However, morbidity resulting from the ingestion of contaminated water persists globally, and the available ep idemiological evidence (Waterborne Diseases in the United States, G. F. Craun, ed. , 1986, CRC Press) demonstrates a dramatic increase in the number of waterborne outbreaks and individual cases within the United States since the mid-1960s. In addition, it should also be noted that the incidence of water borne outbreaks of unknown etiology and those caused by "new" pathogens, such as Campylobaeter sp. , is also increasing in the United States. Although it might be debated whether these increases are real or an artifact resulting from more efficient reporting, it is clear that waterborne morbidity cannot be ignored in the industrialized world. More significantly, it represents one of the most important causes of illness within developing countries. Approxi mately one-half the world's population experiences diseases that are the direct consequence of drinking polluted water. Such illnesses are the primary cause of infant mortality in many Third World countries.
