D EVELOPMENT OF AN A RSENIC M ITIGATION S TRATEGY FOR B ANGLADESH Brian Clifton and Stewart Harwood, University of Oklahoma Executive Summary An activated alumina-based arsenic removal device has been developed and optimized for arsenic removal from well water in rural Bangladesh. The cost of implementing this plan is $4.79 per person, for each of the 80 million people affected. The cost over the ten year lifespan of the project is $383 million. The activated alumina device is designed to connect directly to the existing pumps used to draw water out of the wells, and to provide clean water at a spigot on the side of the device. Bangladesh has a population of 140 million people. Since 1993, arsenic contamination has been discovered in the majority of Bangladesh’s groundwater wells. The World Health Organization (WHO) standard for arsenic in drinking water is 10 ppb or less. Thirty million people in Bangladesh are currently drinking water with greater than 50 ppb arsenic, and fifty million people are drinking water with levels between 10 and 50 ppb. The figure below illustrates the widespread nature of the problem, by showing the percentage of people in each region of the country drinking toxic levels of arsenic.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
