 Water resources are at risk around the globe, including at taps here in the United States.

As growing demand for clean water stretches even the resources of the world's largest industrialized nations, scientists and engineers are turning to new technology and novel ideas to find solutions. |
"As dire as the growing problems are with a lack of enough clean water in the world, I have a great deal of hope that many of these problems can be solved by increasing research into the science and technology of water purification," said Shannon, who also serves as director of the National Science Foundation (NSF) Center of Advanced Materials for the Purification of Water with Systems (WaterCAMPWS).
 One new approach to disinfection was described last spring by researchers from the University of Illinois at Urbana-Champaign. They demonstrated a new class of synthetic antimicrobials that disinfect by inducing negative curvature in bacterial membranes, generating pores. The research by Lihua Yang and colleagues appeared in the Oct. 10, 2007, Journal of the American Chemical Society Credit: Gerard Wong, University of Illinois at Urbana-Champaign | With an emphasis on environmentally friendly tools for killing microbes, membrane bioreactors, nanoscale filtration, and a host of other advanced technologies, the review paper addresses how these systems can be used for disinfection, decontamination, reuse and reclamation, and desalination of water supplies across the globe. "Clearly, a coordinated, multi-faceted approach is needed to deal with complex water issues," said Geoffrey Prentice, the NSF program director supporting the WaterCAMPWS center and currently on detail to the U.S. Mission to UNESCO in Paris. |
One example is a June 27 international water forum at the Department of State at which NSF, UNESCO and a number of agencies and international organizations will be joining Shannon and other technical experts to confront some of the most pressing global water needs.
Shannon will lead the Congress for Water Purification Science and Technologies in the 21st Century in New Orleans on April 6-10, 2008, an event that coincides with an NSF public webcast on April 10 called Water in 2025, co-hosted by Popular Mechanics. Part of the larger Bridges to the Future forum (www.nsf.gov/bridges), the event is an opportunity for the public to call-in and ask questions of some of the top water researchers in the United States. -NSF-

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering, with an annual budget of $5.92 billion. NSF funds reach all 50 states through grants to over 1,700 universities and institutions. Each year, NSF receives about 42,000 competitive requests for funding, and makes over 10,000 new funding awards. The NSF also awards over $400 million in professional and service contracts yearly.
