Download or read book Water Reuse written by National Research Council and published by National Academies Press. This book was released on 2012-07-17 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.

Available in PDF, EPUB and Kindle. Book excerpt: This book gives a comprehensive presentation of our present understanding of the Earth's Hydrological cycle and the problems, consequences and impacts that go with this topic. Water is a central component in the Earth's system. It is indispensable for life on Earth in its present form and influences virtually every aspect of our planet's life support system. On relatively short time scales, atmospheric water vapor interacts with the atmospheric circulation and is crucial in forming the Earth's climate zones. Water vapor is the most powerful of the greenhouse gases and serves to enhance the tropospheric temperature. The dominant part of available water on Earth resides in the oceans. Parts are locked up in the land ice on Greenland and Antarctica and a smaller part is estimated to exist as groundwater. If all the ice over the land and all the glaciers were to melt, the sea level would rise by some 80 m. In comparison, the total amount of water vapor in the atmosphere is small; it amounts to ~ 25 kg/m2, or the equivalent of 25 mm water for each column of air. Yet atmospheric water vapor is crucial for the Earth’s energy balance. The book gives an up to date presentation of the present knowledge.

Download or read book Population and Land Use in Developing Countries written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: This valuable book summarizes recent research by experts from both the natural and social sciences on the effects of population growth on land use. It is a useful introduction to a field in which little quantitative research has been conducted and in which there is a great deal of public controversy. The book includes case studies of African, Asian, and Latin American countries that demonstrate the varied effects of population growth on land use. Several general chapters address the following timely questions: What is meant by land use change? Why are ecological research and population studies so different? What are the implications for sustainable growth in agricultural production? Although much work remains to be done in quantifying the causal connections between demographic and land use changes, this book provides important insights into those connections, and it should stimulate more work in this area.

This book was released on 2012-12-06 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers selected from those presented at the International Symposium on the Analysis of Hydrocarbons and Halogenated Hydrocarbons in the Aquatic Environment, May 23-25, 1978. The Symposium was organized by the National Water Research Institute of Environment Canada and the Institute for Environmental Studies of the University of Toronto. The purpose of the Symposium and of this volume was to bring together information on the analyses, behaviour and effects of hydro carbons and halogenated hydrocarbons on the aquatic environment. This class of contaminants presents many difficult analytical pro blems, and to a large extent our ability to identify environmental problems and assess their severity, depends on the availability of proved analytical techniques. By exposing workers in this field to the techniques and results of others we hope that progress can be made towards solving the many problems caused by these substances. The papers in this volume are divided into five categories: two plenary session addresses given by J.P. Bruce and O. Hutzinger, 11 papers describing quantitative analytical results, 12 papers on analytical methods, 9 papers on incidence, monitoring and pathways; and finally, 13 papers on drinking water, health and biological effects. We were fortunate in having the support of the many organizations and individuals listed after this preface. In particular we thank B.F. Scott and R. Knechtel for their help in organizing the Symposium, S. Paterson, C. Straka, B. Reuber, A. Bobra, R. Wan, S. Austin, G.E.
