Randy Atkins:  Tube wells bring underground water to people in many parts of the world.  But, for millions, it’s naturally laced with arsenic.

Abul Hussam:  My own home in Bangladesh, we had two tube wells, and both of them were contaminated.

Randy Atkins:  Abul Hussam, of George Mason University, just won the Grainger Challenge Prize for a simple household method of removing arsenic.  Gravity forces water through three specially-designed filters in a series of stacked buckets.

Abul Hussam:  It’s about thirty-five dollars, and it is guaranteed to work for five years.

Randy Atkins:  Hussam says his relatives now have safe water, and he’ll use the prize money to bring his technology to others.  With the National Academy of Engineering, Randy Atkins, WTOP Radio.
