Small communities violate federal requirements for safe drinking water as much as three times more often than cities. Yet these communities often cannot afford to improve their water service. Safe Water From Every Tap reviews the risks of violating drinking water standards and discusses options for improving water service in small communities. Included are detailed reviews of a wide range of technologies appropriate for treating drinking water in small communities. The book also presents a variety of institutional options for improving the management efficiency and financial stability of water systems.
An in-depth look at the changing approaches that environmentalists, governments, and the open market have taken to water through the lens of world history. When we turn on the tap or twist open a tall plastic bottle, we probably don’t give a second thought about where our drinking water comes from. But how it gets from the ground to the glass is far more convoluted than we might think. In this revised edition of Drinking Water, Duke University professor and environmental policy expert James Salzman shows how drinking water highlights the most pressing issues of our time. He adds eye-opening, contemporary examples about our relationship to and consumption of water, and a new chapter about the atrocities that occurred in Flint, Michigan. Provocative, insightful, and engaging, Drinking Water shows just how complex a simple glass of water can be. “A surprising, delightful, fact-filled book.” —Jared Diamond, Pulitzer Prize–winning author of Guns, Germs, and Steel “Instead of buying your next twelve-pack of bottled water, buy this fascinating account of all the people who spent their lives making sure you’d have clean, safe drinking water every time you turned on the tap.” —Bill McKibben, author of Earth: Making a Life on a Tough New Planet “Drinking Water effortlessly guides us through a fascinating world we never consider. Even for people who think they know water, there is a surprise on almost every page.” —Charles Fishman, bestselling author of The Big Thirst and The Wal-Mart Effect “Salzman puts a needed spotlight on an often overlooked but critical social, economic, and political resource.” —Publishers Weekly

Most people associate fluoride with the practice of intentionally adding fluoride to public drinking water supplies for the prevention of tooth decay. However, fluoride can also enter public water systems from natural sources, including runoff from the weathering of fluoride-containing rocks and soils and leaching from soil into groundwater. Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States fluoride concentrations in water are much higher than normal, mostly from natural sources. Fluoride is one of the drinking water contaminants regulated by the U.S. Environmental Protection Agency (EPA) because it can occur at these toxic levels. In 1986, the EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter, a guideline designed to prevent the public from being exposed to harmful levels of fluoride. Fluoride in Drinking Water reviews research on various health effects from exposure to fluoride, including studies conducted in the last 10 years.
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.
This book provides an updated evaluation of the characterization and management of taste and odour (T&O) in source and drinking waters. Authored by international experts from the IWA Specialist Group on Off-flavours in the Aquatic Environment, the book represents an important resource that synthesizes current knowledge on the origins, mitigation, and management of aquatic T&O problems. The material provides new knowledge for an increasing widespread degradation of source waters and global demand for high quality potable water. Key topics include early warning, detection and source-tracking, chemical, sensory and molecular diagnosis, treatment options for common odorants and minerals, source management, modelling and risk assessment, and future research directions. Taste and Odour in Source and Drinking Water is directed towards a wide readership of scientists, engineers, technical operators and managers, and presents both practical and theoretical material, including an updated version of the benchmark Drinking Water Taste and Odour Wheel and a new biological wheel to provide a practical and informative tool for the initial diagnosis of the chemical and biological sources of aquatic T&O.
Other than air, the only substance more vital to life is water. Our bodies brim with it, and if we’re deprived of it for even a few days, the results can be fatal. Our planet, too, is mostly water, with oceans across approximately seventy percent of its surface. But potable water has in many times and places been a scarce resource, and with Water, Ian Miller traces the history of our relationship with drinking water—our attempts to find it, keep it clean, and make it widely available. Miller’s history ranges widely, from ancient times to the present, exploring all the many ways that we’ve rendered water palatable—from boiling it for tea or distilling it as part of alcoholic beverages to piping it from springs, bubbles and all. He covers the histories of water treatment and supply, belief in its medicinal powers, and much more, all supported by fascinating historical illustrations. As access to fresh water becomes an ever more potent problem worldwide, Miller’s book is a fascinating reminder of our long engagement with this most vital fluid.

The safety of the nation's drinking water must be maintained to ensure the health of the public. The U.S. Environmental Protection Agency (EPA) is responsible for regulating the levels of substances in the drinking water supply. Copper can leach into drinking water from the pipes in the distribution system, and the allowable levels are regulated by the EPA. The regulation of copper, however, is complicated by the fact that it is both necessary to the normal functioning of the body and toxic to the body at too high a level. The National Research Council was requested to form a committee to review the scientific validity of the EPA's maximum contaminant level goal for copper in drinking water. Copper in Drinking Water outlines the findings of the committee's review. The book provides a review of the toxicity of copper as well as a discussion of the essential nature of this metal. The risks posed by both short-term and long-term exposure to copper are characterized, and the implications for public health are discussed. This book is a valuable reference for individuals involved in the regulation of water supplies and individuals interested in issues surrounding this metal.
