Creativity Prize

Overview

psipw5thwinnersteam 4web 4The team of Dr. Ashok Gadgil, Dr. Susan Addy, Case van Genuchten (University of California Berkley, USA ), Dr. Robert Kostecki (Lawrence Berkeley National Laboratory) and Dr. Joyashree Roy (Jadavpur University, Kolkata).

The prize is awarded to this team of researchers for developing an innovative and effective method of treating the arsenic contamination of groundwater using electrocoagulation.

They have produced an exemplary work of fundamental and applied science which runs the complete course from initial research to functioning prototype, while addressing one of the most serious drinking water problems confronting the human population in developing countries.

Suffice it to say that 1 in 5 of all adult deaths in Bangladesh are presently due to chronic arsenic poisoning. About 100 million people in Bangladesh and in the nearby Indian state of West Bengal are exposed to very high levels of naturally occurring arsenic in groundwater, which is their main source of drinking water. The World Health Organization recommends a maximum contaminant limit (MCL) for arsenic in drinking water of 10 μg/liter; in some areas of Bangladesh arsenic levels are as high as 800 μg/liter. This has rightly been called the largest case of mass poisoning in world history.

Arsenic pollution of groundwater is a widespread problem in other deltaic sediments around the globe. Millions of people suffer from latent arsenic poisoning, culminating in many dangerous diseases, including cancer.  There has long been a need for a simple and inexpensive method of treating arsenic contaminated water, which will save millions of people from arsenic poisoning and related health problems.

The possible impact of the method developed by the group – the best and most cost-effective method available to date – is huge. Even though the group’s research draws on a previously known electrocoagulation process, its scientific and practical value is high.

It is not sufficient to just establish that electrochemical reactions can precipitate arsenic. It is equally important to establish the stability of the precipitate and its behaviour under different electrolysis conditions and with other ions present. The team has carried out this evaluation in a careful and comprehensive way using advanced synchrotron-based X-ray characterization techniques (EXAFS).

They have also considered the disposal of wastes. They have exhibited creativity by transforming this scientific knowledge successfully into an easy-to-understand and easy-to-operate, locally affordable technology.

Finally, the analysis of societal implementation is convincing, going for a community approach rather than an individual application in each household. This excludes errors in operation and guarantees achieving economies of scale. The required voltage of 3 V can be provided by photovoltaic cells. The estimated price of safe groundwater at 4 US cents per 10 litres is comparatively low and acceptable even for the very poor.

Acceptance Speech

gadgilspeaking300x300His Royal Highness Crown Prince Salman Bin Abdulaziz Al Saud, His Royal Highness Prince Khaled Bin Sultan Bin Abdulaziz, honorable members of the Prize Council, and distinguished guests and colleagues...   It is a great honor for my team, and me personally, to be selected for the Prince Sultan International Prize for Water’s Creativity Prize, for the 5th Biennial Cycle of the Award. We would like to express our deep gratitude to the distinguished members of the Preliminary Screening Committee, the Referee Committee, the Selection Committee, and the Prize Council of the Prince Sultan Prize, chaired by HRH Prince Khaled Bin Sultan Bin Abdulaziz.

Water is Life.  Life cannot exist without water.  And to enable healthy life by providing healthful, clean, and life-supporting water -- is one of the most satisfying, compassionate, and life-affirming activities possible.

Imagine how unfair life is for the tens of millions of arsenic-afflicted people – mostly also very poor – when the very water they drink is killing them slowly, but surely and painfully.  On top of it is the psychological pain and suffering of social rejection of young women by their families, or by their spouses, when they get disfigured, or develop terminal diseases, or get into intergenerational indebtedness to buy treatment.  This is what arsenic in drinking water threatens to do to millions of people who must drink it every day.

Our team strived to ensure that the safe drinking water produced with our ECAR technology, is locally affordable to the poorest communities; that the technology is robust and reliable in harsh and difficult field operating conditions; easy to maintain, and based on new and deeper understanding of the basic science.  We strive to ensure that it is socially placed in a correct way so that communities can accept it from the start.  And we also pay attention to the safe disposal of the arsenic-laden waste that must result from removing the arsenic from the water.

We take this opportunity to recognize our numerous funding supporters, especially LBNL, US EPA’s P3 program, the NCIIA, UC Berkeley’s Blum Center, the Sustainable Products and Solutions program, and the Big Ideas competition.  And most importantly we recognize the dedicated efforts of many student-volunteers from Berkeley, who worked selflessly to advance this technology.

In closing, we note that in awarding us this distinguished prize, the honorable members of the selection committees and the Prize Council took a view that is both intellectually rigorous and informed by compassion.  In addition to rigorous engineering science, it also values social-science and relevance.

We are pleased that this prize highlights creative work to alleviate human suffering on the planet related to our most precious asset, water.  Demanding such high and broad standards is both highly valuable and rare.  We are especially pleased and humbled that the distinguished jury selected our work when judging against these lofty standards.

Thank you.
