Book Description
The quality of drinking water is paramount for public health. Despite important improvements in the last decades, access to safe drinking water is not universal. The World Health Organization estimates that almost 10% of the population in the world do not have access to improved drinking water sources. Among other diseases, waterborne infections cause diarrhea, which kills nearly one million people every year, mostly children under 5 years of age. On the other hand, chemical pollution is a concern in high-income countries and an increasing problem in low- and middle-income countries. Exposure to chemicals in drinking water may lead to a range of chronic non-communicable diseases (e.g., cancer, cardiovascular disease), adverse reproductive outcomes, and effects on children’s health (e.g., neurodevelopment), among other health effects. Although drinking water quality is regulated and monitored in many countries, increasing knowledge leads to the need for reviewing standards and guidelines on a nearly permanent basis, both for regulated and newly identified contaminants. Drinking water standards are mostly based on animal toxicity data, and more robust epidemiologic studies with accurate exposure assessment are needed. The current risk assessment paradigm dealing mostly with one-by-one chemicals dismisses the potential synergisms or interactions from exposures to mixtures of contaminants, particularly at the low-exposure range. Thus, evidence is needed on exposure and health effects of mixtures of contaminants in drinking water. Finally, water stress and water quality problems are expected to increase in the coming years due to climate change and increasing water demand by population growth, and new evidence is needed to design appropriate adaptation policies. This Special Issue of International Journal of Environmental Research and Public Health (IJERPH) focuses on the current state of knowledge on the links between drinking water quality and human health.

Book Description
In today’s chemically dependent society, environmental studies demonstrate that drinking water in developed countries contains numerous industrial chemicals, pesticides, pharmaceuticals and chemicals from water treatment processes. This poses a real threat. As a result of the ever-expanding list of chemical and biochemical products industry, current drinking water standards that serve to preserve our drinking water quality are grossly out of date. Environmental Science of Drinking Water demonstrates why we need to make a fundamental change in our approach toward protecting our drinking water. Factual and circumstantial evidence showing the failure of current drinking water standards to adequately protect human health is presented along with analysis of the extent of pollution in our water resources and drinking water. The authors also present detail of the currently available state-of-the-art technologies which, if fully employed, can move us toward a healthier future. * Addresses the international problems of outdated standards and the overwhelming onslaught of new contaminants. * Includes new monitoring data on non-regulated chemicals in water sources and drinking water.* Includes a summary of different bottled waters as well as consumer water purification technologies.

Book Description
In the beginning of the 21st century, we find ourselves awakening to a water crisis. The signs are everywhere. From deaths attributed to waterborne diseases and lack of water to economic losses due to poor environmental planning, the evidence is building. Because water touches our lives in so many ways, each of us must understand its importance - particularly health professionals, who may be more impacted by issues of water than they realise. Dr. Magee examines the many nuances of water in our lives - including its impact on health, energy, cities, industry and economies. His discussion of natural water disasters touches on many of the core problems raised by the tragedy of Hurricane Katrina.

Book Description
"Water is a molecular marvel. Its seemingly simple formula - H2O -dictates the properties that make water essential for life and easily contaminated. Herein lies the paradox of water-we cannot live without it, but it is easily rendered "unsafe." The Paradox of Water explores the intersection of the scientific, social, and policy implications around access to safe drinking water. Drinking water is the smallest fraction of water used by a nation, yet, access to safe drinking water supports educational opportunities, helps overcome gender inequities, lowers familial stress, and enables more socially and economically productive uses of time"--

Book Description
This work provides those involved in water purification research and administration with a comprehensive resource of methods for analyzing water to assure its safety from contaminants, both natural and human caused. The book first provides an overview of major water-related issues in developing and developed countries, followed by a review of issues of sampling for water analysis, regulatory considerations and forensics in water quality and purity investigations. The subsequent chapters cover microbial as well chemical contaminations from inorganic compounds, radionuclides, volatile and semi-volatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, as well as potential terrorist-related contamination. The last chapter describes the Grainger prize-winning filter that can remove arsenic from water sources and sufficiently protect the health of a large number of people. Covers the scope of water contamination problems on a worldwide scale Provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants Describes the filter that won the $1 million Grainger prize and thereby highlighting an important approach to remediation

Book Description
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.

Book Description
Water is our most essential element. Every day we drink it, bathe in it, cook with it and wash with it. What do we know about our water? Where does it come from? Is it clean? Is it healthy? Perhaps it is polluted or toxic. Perhaps what comes out of our faucet is making us sick. Perhaps we are slowly poisoning our bodies. Or perhaps not, depending upon our water source and treatment method. "Pure Water" engages all of these questions and more. Here the latest scientific discoveries about water and its many magical and healing properties are unveiled. Here the latest research on water pollutants and contamination sources are exposed. Here we discover our options for home filtration, the truth about bottled water, and the facts on water treatment. From "Pure Water" we gain clarity regarding the epidemic of dehydration, and discover how to use water to heal and feel better every day.
