Prof. Lennart Olsson from LUCSUS was the moderator for the day, and introduced the semiar by referring to the first time he came across the problems with arsenic in ground water, in an article in Science in 1988.
Prof. Torleif Dahlin, Division of Engineering Geology, Lund University, gave the first presentation. He gave a broad overview about groundwater in general, the presentation entitled ”Groundwater – the hidden resource. A world survey”.
See his presentation.
Prof. Prosun Bhattacharya, who leads the International Groundwater Arsenic Research Group (GARG) at KTH, came next, putting specific focus on the arsenic problems in his presentation entitled ”Global Overview of Natural Arsenic in Groundwater – Perspectives and Challenges”. See his presentation.
Prof. Marie Vahter, Division of Metals & Health, Institute of Environmental Medicine (IMM), Karolinska Institutet, Stockholm, is a world leading expert on the health hazards connected not only to arsenic but also to other metals prevalent in drinking water. In her presentation, entitled ”Health effects of arsenic with special focus on early-life exposure”, she pointed out the extremely damaging effects that Arsenic poisoning causes to human lives. The skin defects often shown are not the worst, but instead its strong cancerogenous effects and how it negatively affects the immunary defence. There is a direct correlation between the mortality rate and high levels of Arsenic in food and water. See her presentation.
Dr. Abul Mandal, School of Life Sciences, Skövde University, then talked about his ongoing research project, focusing on ”Studies of genes involved in uptake and/or metabolism of arsenics in plants: A practical approach for protection of human from arsenic contamination”. By developing new varieties of rice it may be possible to reduce the amount of arsenic taken up by the plants from the irrigation water commonly used for rice cultivationin Bangladesh. See his presentation.
Prosun Bhattacharya (photo to the right) came back and gave a second presentation, entitled ”Strategies for Sustainable Arsenic Mitigation in Bangladesh”, focusing on the experiences from the major Sida-funded Sustainable Arsenic Mitigation (SASMIT) project that his research grouphas been engaged in since 2007. The project aims to develop community driven initiatives to target arsenic safe groundwater as sustainable mitigation strategy (more information about the project).
See Prosun Bhattacharya’s second presentation.
Prosun was followed by Mr. Mattias von Brömssen, previously connected as a PhD candidate to the same research group at KTH, but now working for Ramböll Sweden in Stockholm, at its Department for Water Resources Management. He talked about ”Challenges for providing safe drinking water in regions with high As-groundwater in Bangladesh”.
See his presentation.
Finally, Ms. Eva Hägerstrand, Coordinator for the Swallows India-Bangladesh Section, based in Lund, talked about ”The Drinking water situation in rural Bangladesh today”. Her talk was based upon interviews that Mr. Raihan Ali, working for the Thanapara Swallows Development Society in Rajshahi district, Bangladesh, has made with local villagers. From their responses it is clear that there is now a conciousness about the problem, and local solutions are tried to improve the situation.

After the presentations, a panel debate was organised with all the speakers, with much input from the audience, not the least from H.E. Mr. Imtiaz Ahmed, Ambassador of Bangladesh to Sweden, who was the guest of honour during the day. Lennart Olsson from LUCSUS led the debate and tried to initiate a discussion on accountability, whether anybody could be blamed for the current situation.
The massive well boring project in Bangladesh funded by Sida, the Swedish Development Cooperation Agency, in the past carried out without proper water analysis in beforehand, was for example highlighted in media some years ago. The panel was however mild in its judgement, saying that it is not possible to demand responsibility from a funding agency for a failed project several years afterwards. Besides the main responsibility for monitoring the water quality must be put on the owners.

Marie Vahter also warned against only focusing on Arsenic when it comes to testing drinking water. Other elements may be as harmful for the human body as Arsenic, and therefore a comprehensive testing is needed.
Most of the discussion focused on existing alternative methods to improve the situation in Bangladesh. One suggestion was to build big wells that are free of Arsenic and build a distribution system from these, a solution that has been used for example in Chile. Other effective means like installing filters, and harvesting of rainwater, were also pointed out. There are however economic, and social barriers that makes it difficult to introduce costly apparatus, and even a cultural barrier in changing people’s behaviour regarding the use of drinking water.
Funding for the seminar was kindly provided by Swedish Water House (SWH) in Stockholm, and Sydvatten AB in Malmö.
It was held at Geocentrum, Sölvegatan 10 in Lund.
