KNIGHTDALE -- If you want to know the secret to Joe Kanze's luscious green lawn, look under the fake rock. There, in his backyard, you'll find a recently drilled irrigation well topped with a high-tech Danish water pump. At the touch of a button, Kanze can douse his third-of-an-acre lot with 12 gallons a minute of groundwater. "It was an expensive deal," says Kanze, 72, who paid more than $6,000 to have the well and pump installed last month. "But you know what? I'm retired now and this is...

By Rotzoll, Kolja; El-Kadi, Aly I; Gingerich, Stephen B ABSTRACT: In recent years the ground-water demand of the population of the island of Maui, Hawaii, has significantly increased. To ensure prudent management of the ground-water resources, an improved understanding of ground-water flow systems is needed. At present, large-scale estimations of aquifer properties are lacking for Maui. Seven analytical methods using constant-rate and variable-rate withdrawals for single wells provide an...

By Jennifer Smith, Newsday, Melville, N.Y. Mar. 19--For most Long Islanders, effects from two weeks of torrential rains in October 2005 subsided when the puddles dried. But in two low-lying areas of Smithtown, the repercussions to local groundwater have resulted in an enduring, mold-spotted dankness for those whose homes now sit on, instead of above, the water table. Groundwater levels from Westbury to Westhampton Beach surged after the 2005 rains as the deluge of water worked its way...

By Maliva, Robert G; Guo, Weixing; Missimer, Thomas M ABSTRACT: Aquifer storage and recovery (ASR) is part of the solution to the global problem of managing water resources to meet existing and future freshwater demands. However, the metaphoric "ASR bubble" has been burst with the realization that ASR systems are more physically and chemically complex than the general conceptualization. Aquifer heterogeneity and fluid-rock interactions can greatly affect ASR system performance. The results...

Recent space observations of freshwater storage by the Gravity Recovery and Climate Experiment (Grace) are providing a new picture of how Earth's most precious natural resource is distributed globally and how it is changing. Researchers are using the mission's almost five-year data record to estimate seasonal water storage variations in more than 50 river basins that cover most of Earth's land area. The variations reflect changes in water stored in rivers, lakes and reservoirs; in...

By Christine Stebbins CHICAGO -- As the United States bakes in one of the hottest summers since the Dust Bowl years of the 1930s, drought from the Dakotas to Arizona through Alabama has sharpened the focus of farmers on their lifeline: water. Eighty percent of all fresh water consumed in the United States is used to produce food. But years of drought, diversion of water to growing urban areas and, most lately, concerns about global warming are feeding worries. Specifically, farmers fear the...

ALBANY, N.Y. (AP) -- A growing population coupled with diminishing fresh water supplies should force major changes in the way the world's farmers water their crops in the coming decades, a recent study recommends. Since agriculture uses about 70 percent of the world's fresh water every year, farming should be the focus of intense conservation efforts, said David Pimentel, a professor at Cornell University and primary author of the study published in the October issue of the journal...

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...
