Book Description
Giardia duodenalis (=G. lamblia), Entamoeba histolytica, Cryptosporidium parvum and Cyclospora cayetanensis are more than just a mouthful for most who might encounter them. These protozoan parasitic agents contribute significantly to the staggering caseload of diarrheal disease morbidity encountered in developing world nations. Compounding the issue of their mere presence is the fact that standard ova and parasite exams frequently do not detect these infections. Detectable stages may be shed intermittently or require specialized staining procedures. Added to this is the often large number of asymptomatic carriers who serve as reservoirs for infecting others. These parasites are also not strangers to more developed nations, having responsibility for both small and large-scale disease outbreaks. In such settings they may be even more difficult to detect simply because they are frequently overlooked in the grand scheme of disease causing possibilities. They share common features; all are Protozoa, all possess trophic stages that inhabit the gastrointestinal tract, all have the ability to produce disease and in some instances death, and all produce environmentally stable cysts or oocysts, which ensure their transmissibility. In other ways, these organisms are profoundly different. Giardia is a flagellate that inhabits the gut lumen in close association with enterocytes. Entamoeba is an amoeba that preferentially inhabits the mucosal region of the gut lumen, but which may, under certain circumstances, become invasive. Cryptosporidium and Cyclospora are obligate intracellular coccidians, each taking up a unique niche within their respective host enterocytes.

Book Description
Twort's Water Supply, Seventh Edition, has been expanded to provide the latest tools and techniques to meet engineering challenges over dwindling natural resources. Approximately 1.1 billion people in rural and peri-urban communities of developing countries do not have access to safe drinking water. The mortality from diarrhea-related diseases amounts to 2.2 million people each year from the consumption of unsafe water. This update reflects the latest WHO, European, UK, and US standards, including the European Water Framework Directive. The book also includes an expansion of waste and sludge disposal, including energy and sustainability, and new chapters on intakes, chemical storage, handling, and sampling. Written for both professionals and students, this book is essential reading for anyone working in water engineering. - Features expanded coverage of waste and sludge disposal to include energy use and sustainability - Includes a new chapter on intakes - Includes a new chapter on chemical storage and handling

Book Description
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.
