Can calcium and magnesium ("hardness") in drinking water contribute to preventing disease? This book documents the outputs of an unprecedented group of experts assembled by the World Health Organization to address this question. It includes their comprehensive consensus view on what is known and what is not about the role and possible health benefit of calcium and magnesium in drinking-water. Also included is a series of chapters each authored by internationally renowned experts reviewing the state of the art in different aspects including: global dietary calcium and magnesium intakes; the contribution of drinking water to calcium and magnesium intake; health significance of calcium and magnesium; role of drinking-water in relation to bone metabolism; epidemiological studies and the association of cardiovascular disease risks with water hardness and magnesium in particular; water production; technical issues and economics. In both developed and developing countries, typical diets are often deficient in calcium and magnesium--essential minerals which are necessary for the development of strong bones and teeth, and for cardiovascular function. At the same time, there is evidence that consuming "hard" drinking-water may be associated with reduced risks for some diseases. Climate change and other ongoing changes will increase the use of high tech treatments--for example desalination and reclamation of polluted waters and mean that the issue will be of increasing future importance.

A range of natural earth materials, like arsenic or fluoride, have long been linked to significant human health effects. Improved understanding of the pervasive and complex interactions between earth materials and human health will require creative collaborations between earth scientists and public health professionals. At the request of the National Science Foundation, U.S. Geological Survey, and National Aeronautics and Space Administration, this National Research Council book assesses the current state of knowledge at the interface between the earth sciences and public health disciplines. The book identifies high-priority areas for collaborative research, including understanding the transport and bioavailability of potentially hazardous earth materials, using risk-based scenarios to mitigate the public health effects of natural hazards under current and future climate regimes, and understanding the health risks that result from disturbance of earth systems. Geospatial information - geological maps for earth scientists and epidemiological data for public health professionals - is identified as one of the essential integrative tools that is fundamental to the activities of both communities. The book also calls for increased data sharing between agencies to promote interdisciplinary research without compromising privacy.

This volume is of great importance to humans and other living organisms. The study of water quality draws information from a variety of disciplines including chemistry, biology, mathematics, physics, engineering, and resource management. University training in water quality is often limited to specialized courses in engineering, ecology, and fisheries curricula. This book also offers a basic understanding of water quality to professionals who are not formally trained in the subject. The revised third edition updates and expands the discussion, and incorporates additional figures and illustrative problems. Improvements include a new chapter on basic chemistry, a more comprehensive chapter on hydrology, and an updated chapter on regulations and standards. Because it employs only first-year college-level chemistry and very basic physics, the book is well-suited as the foundation for a general introductory course in water quality. It is equally useful as a guide for self-study and an in-depth resource for general readers.

In its third edition, this praised book demonstrates how the living systems modeling of aquatic ecosystems for ecological, biological and physiological research, and ecosystem restoration can produce answers to very complex ecological questions. Dynamic Aquaria further offers an understanding developed in 25 years of living ecosystem modeling and discusses how this knowledge has produced methods of efficiently solving many environmental problems. Public education through this methodology is the additional key to the broader ecosystem understanding necessary to allow human society to pass through the next evolutionary bottleneck of our species. Living systems modeling as a wide spectrum educational tool can provide a primary vehicle for that essential step. This third editon covers the many technological and biological developments in the eight plus years since the second edition, providing updated technological advice and describing many new example aquarium environments. - Includes 16 page color insert with 57 color plates and 25% new photographs - Offers 300 figures and 75 tables - New chapter on Biogeography - Over 50% new research in various chapters - Significant updates in chapters include: - The understanding of coral reef function especially the relationship between photosynthesis and calcification - The use of living system models to solve problems of biogeography and the geographic dispersal and interaction of species populations - The development of new techniques for global scale restoration of water and atmosphere - The development of new techniques for closed system, sustainable aquaculture

Growing demands for water in many parts of the nation are fueling the search for new approaches to sustainable water management, including how best to store water. Society has historically relied on dams and reservoirs, but problems such as high evaporation rates and a lack of suitable land for dam construction are driving interest in the prospect of storing water underground. Managed underground storage should be considered a valuable tool in a water manager's portfolio, although it poses its own unique challenges that need to be addressed through research and regulatory measures.
