The papers in this issue of The Bridge describe some recent advances in the search for water, in the distribution and treatment of water and wastewater, and in the modeling of complex water systems. Articles In This Issue Arsenic Filters for Groundwater in Bangladesh: Toward a Sustainable Solution Monday, September 1, 2008 AuthorAbul Hussam, Sad Ahamed, and Abul K.M. Munir A simple filtration system used in Bangladesh and other countries removes dangerous arsenic from drinking water. The natural presence of arsenic and other toxins in groundwater, the most common source of drinking water, is considered a worldwide public-health crisis and an unprecedented natural ... Living with a Changing Water Environment Monday, September 1, 2008 AuthorJerald L. Schnoor Networks of volunteers working within a common framework to improve water quality can transcend geopolitics. Water, like all things on planet Earth, is changing. But the changes in water resources are attributable primarily to human activities, not natural causes. Four major factors profoundly ... New Approaches and Technologies for Wastewater Management Monday, September 1, 2008 AuthorGlen T. Daigger Integrated closed-loop systems for recycling water and waste material can meet consumer demands and satisfy environmental imperatives. In the past decade, practical applications of a variety of new wastewater-treatment technologies, such as membrane filtration systems and advanced oxidation, ... Remote Sensing of the Earth: Implications for Groundwater in Darfur Monday, September 1, 2008 AuthorFarouk El-Baz Satellite images and sophisticated mapping techniques are revealing new sources of fresh water in surprising places. Images of Earth from space have improved steadily during the past 40 years. In the mid-1960s, photographs taken by astronauts of the Gemini, Apollo, Skylab, and Apollo-Soyuz ... Water-Distribution Systems: The Next Frontier Monday, September 1, 2008 AuthorVanessa Speight Water-distribution systems, the last barriers in the water-treatment process, are vital to protecting public health. Technologies for treating drinking water have advanced significantly over the past century. Today the availability of abundant, clean, safe drinking water, on demand at every ... Water Resource Management Models Monday, September 1, 2008 AuthorDaniel P. Loucks Water-resource models have been used to inform decisions about water supplies, ecological restoration, and water management in complex regional systems. Water-resources development projects inevitably include economic, environmental, and social considerations, as well as computer-based models ... Water: Advances in the Supply and Management of a Vital Resource (Editorial) Monday, September 1, 2008 AuthorGeorge Bugliarello Editor’s Note We cannot live without water, and our civilization would collapse without it. But water can also destroy us and our way of life, because, since neolithic times, people have tended to settle near water—on deltas, near rivers, and along coastlines. It has been estimated ...
