Latest Sono arsenic filter Stories
Over 100 million people in rural southern Asia are exposed every day to unsafe levels of arsenic from the well-water they drink.
Researchers in MIT's Department of Civil and Environmental Engineering believe they have pinpointed a pathway by which arsenic may be contaminating the drinking water in Bangladesh, a phenomenon that has puzzled scientists, world health agencies and the Bangladeshi government for nearly 30 years.
A professor who developed an inexpensive, easy-to-make system for filtering arsenic from well water has won a $1 million engineering prize - and he plans to use most of the money to distribute the filters to needy communities around the world.
