An epidemiologist from the University of California at Berkley recently won $1 Million dollars for developing a system to filter arsenic from well water. His maintenance-free filter uses sand, charcoal, bits of bricks and shards of cast iron, and 20 pounds of porous iron. The iron forms a chemical bond with the arsenic.
He plans to spend $700,000 to build and distribute the filters to needy communities, $250,000 for further research, and $50,000 will be donated to the George Mason University. These filters cost about $40 each and 200 are being made each week in Kushita, Bangladesh. 30,000 units have already been distributed.
