This book was released on 2001 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waterborne transmission of disease has been documented throughout history. One of the greatest contributions to 20% century society has been the advent and application of water treatment technologies. However, analysis of current World Health Organization (WHO) estimates of illness and mortality and epidemiological investigations in the United States still indicates that the threat to public health from waterborne disease still exists There are a plethora of contaminants (both chemical and microbiological) that impose a direct risk to public health in the United States. The United States Environmental Protection Agency (EPA) reviews these contaminants and focuses its efforts upon the chemicals and microorganisms that are entered on the Contaminant Candidate List (CCL). Although it has never appeared on the CCL, a large amount of research during the 1990s was focused upon Cryptosporidium parvum, a pathogenic waterborne parasite, to fmd methods and techniques to measure, remove, and inactivate it in drinking water supplies. C. parvum gained national public attention in 1993 when cryptosporidiosis in Milwaukee, Wisconsin infected an estimated 403,000 people and killed an estimated 65 to 100 people (MacKenzie, et al., 1994).

This book was released on 2010-12-13 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Special Offer: KWR Drinking Water Treatment Set - Buy all five books together and save a total £119! Safe drinking water is a basic need for all human beings. Preventing microbial contamination of drinking water is of primary concern since endemic illness and outbreaks of infectious diseases can have significant social and economic consequences. Confirming absence of indicators of faecal contamination by water analysis only provides a limited verification of safety. By measuring pathogenic organisms in source water and modelling their reduction by treatment, a higher level of drinking water safety can be verified. This book provides stochastic methods to determine reduction of pathogenic microorganisms by drinking water treatment. These can be used to assess the level and variability of drinking water safety while taking uncertainty into account. The results can support decisions by risk managers about treatment design, operation, monitoring, and adaptation. Examples illustrate how the methods can be used in water safety plans to improve and secure production of safe drinking water.

Download or read book Global Issues in Water Sanitation and Health written by Institute of Medicine and published by National Academies Press. This book was released on 2009-10-25 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the human population grows-tripling in the past century while, simultaneously, quadrupling its demand for water-Earth's finite freshwater supplies are increasingly strained, and also increasingly contaminated by domestic, agricultural, and industrial wastes. Today, approximately one-third of the world's population lives in areas with scarce water resources. Nearly one billion people currently lack access to an adequate water supply, and more than twice as many lack access to basic sanitation services. It is projected that by 2025 water scarcity will affect nearly two-thirds of all people on the planet. Recognizing that water availability, water quality, and sanitation are fundamental issues underlying infectious disease emergence and spread, the Institute of Medicine held a two-day public workshop, summarized in this volume. Through invited presentations and discussions, participants explored global and local connections between water, sanitation, and health; the spectrum of water-related disease transmission processes as they inform intervention design; lessons learned from water-related disease outbreaks; vulnerabilities in water and sanitation infrastructure in both industrialized and developing countries; and opportunities to improve water and sanitation infrastructure so as to reduce the risk of water-related infectious disease.
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.

Download or read book Watershed Management for Potable Water Supply written by National Research Council and published by National Academies Press. This book was released on 2000-02-17 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.
