In the 1960s, scientists developed several ways to turn saltwater into freshwater. All were prohibitively expensive because they required a great deal of energy. But today, the technology has been significantly refined, and demand for fresh water has grown so high in some regions that desalination is getting a second look. A panel talks about desalination technology and how it might change water management in the United States.
- David Furukawa past president of the International Desalination Association
- Richard Drew chief of the bureau of water facilities regulation for the Florida Department of Environmental Protection
- Andrew Macoun a principal water and sanitation specialist for the World Bank
- Erik Olson of the Natural Resources Defense Council
