Book Description
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

Book Description
This book emphasizes the occurrence of sublethal injury in the indicator and pathogenic bacteria commonly encountered in foods, water and feed and modifications of the currently recommended methods for the effective detection of these bacteria. Chapters include methods for recovering injured "classical" enteric pathogenic bacteria from foods and for recovering injured pathogenic organisms from animal food. Detection and significance of injured indicator and pathogenic bacteria in water are explained, as well as detection of injured sporeforming bacteria from foods. This volume is extremely useful for individuals in the academic institutions, industries, federal and state regulatory agencies, public health service and hospitals who are interested in effective detection of indicator and pathogenic bacteria in food and water.

Book Description
A small but growing number of municipalities are augmenting their drinking water supplies with highly treated wastewater. But some professionals in the field argue that only the purest sources should be used for drinking water. Is potable reuse a viable application of reclaimed water? How can individual communities effectively evaluate potable reuse programs? How certain must "certain" be when it comes to drinking water safety? Issues in Potable Reuse provides the best available answers to these questions. Useful to scientists yet accessible to concerned lay readers, this book defines important terms in the debate and provides data, analysis, and examples of the experience of municipalities from San Diego to Tampa. The committee explores in detail the two major types of contaminants: Chemical contaminants. The committee discusses how to assess toxicity, reduce the input of contaminants, evaluate treatment options, manage the byproducts of disinfection and other issues. Microbial contaminants, including newly emerging waterborne pathogens. The book covers methods of detection, health consequences, treatment, and more. Issues in Potable Reuse reviews the results of six health effects studies at operational or proposed reuse projects. The committee discusses the utility of fish versus mammals in toxicology testing and covers issues in quality assurance.

Book Description
The first complete guide to the quantitative assessment of risks to humans posed by infectious agents in all environmental media. Recent highly-publicized infectious disease outbreaks in the United States and abroad have engendered mounting political pressure to require the use of quantitative techniques in the assessment of the risks of human exposure to an array of microorganisms. While traditional indicator methods for pathogen assessment and control have always left much to be desired, it is only with the advent of modern microbial methods that it is now possible to establish rigorous testing protocols for infectious agents comparable to those in place for chemical agents and other contaminants. A book whose time has come, Quantitative Microbial Risk Assessment equips environmental and public health professionals with the knowledge and skills they need to comply with the rapidly growing demand for quantitative risk testing of infectious agents. Authored by an interdisciplinary team of experts from the fields of environmental engineering, marine science, and soil and water science, this is the first comprehensive guide to state-of-the-art quantitative microbial risk assessment methods. It provides you with: * Exhaustive coverage of potential infectious agents and their modes of transmission. * Systematic presentations of quantitative risk, hazard, and exposure assessment techniques. * Numerous worked examples throughout the book. * Fascinating case studies illustrating the application of quantitative methods to various situations. Quantitative Microbial Risk Assessment is an important working resource for professionals in the fields of environmental health, environmental engineering, public health, and microbiology. It is also an excellent graduate-level text for students of those disciplines.
