Removing Arsenic from Contaminated Drinking Water in Rural Bangladesh

University of California, Berkeley, 2007 - $20,000

In Bangladesh, naturally occurring arsenic poisons shallow drinking wells, exposing 30-70 million Bangladeshis to dangerously high levels of the toxin. Most of the people affected by arsenic are among the world’s poorest. To combat the problem, this team from UC Berkeley is developing ARUBA (Arsenic Removal Using Bottom Ash), a simple technology that effectively and affordably removes arsenic from drinking water. The team is partnered with the Bangladesh Rural Advancement Committee (BRAC), the largest NGO in Bangladesh.

The top three objectives of this grant are: (1) Technical: scale up the production of ARUBA to greater than 500g/day, transfer the knowledge required to manufacture ARUBA to collaborators in Bangladesh, and construct a bench-top, proof-of-concept prototype than can be tested in Bangladesh in summer 2008; (2) Socioeconomic: completion of a village economic assessment through creation of a survey which will be administered in Bangladesh in summer 2008; (3) Business: quantify market size and opportunities for profitability, and continue to work towards ARUBA technology licensing.
