Washington: Scientists and engineers together must initiate a major new effort to educate the public and decision makers on a crisis in providing Earth`s people with clean water that looms ahead in the 21st century.
In an article in the weekly newsmagazine of the American Chemical Society (ACS), three scientists - Bassam Z. Shakhashiri, Ph.D., David L. Sedlak, Ph.D., and Jerald L. Schnoor, Ph.D - explain that shortages of reliable supplies of fresh water will touch the lives people everywhere.
In the developing world, nearly 1 billion people lack access to safe drinking water and sanitation because of the absence of distribution systems for clean water, they said.
Needed throughout the world, they state, is a new generation of sustainable water systems. These systems would include new technologies for recycling of municipal and industrial wastewater, more stringent standards for waterborne pollutants and other innovations.
They said that meeting this challenge requires the efforts of chemists, collaborating with engineers and other scientists and influencing decision makers.
