Dr. Siegfried examined the arsenic affected villages Kunwar and Shivamgarh. Relief organizations and NGOs previously installed hand tube and dug wells as well as filtration systems in the area. People, however, are still suffering from arsenicosis symptoms.

Water samples were taken to estimate the arsenic concentration in tube wells and to check the performance of different locally installed filter systems. The samples were transported to Germany for analysis with the ARSOlux biosensor and ICP-MS for comparison purposes. Furthermore, samples were directly analyzed in a lab in Kathmandu to demonstrate the performance of the ARSOlux technology.

Dr. Siegfried participated in a workshop held by the District Development Committee in Parasi. Several members of NGOs and representatives of the local district government, who are working in the arsenic field or are responsible for safe drinking water supply and education, were also participating.


ARSOlux Workshop in Kathmandu (Nepal), 2011

After welcoming the guest speakers and workshop participants from the Nepalese government, WHO, UNICEF, UN-Habitat, NGOs and various research institutions, Mrs. Hahn-Tomer handed over the word to Mr. Hansen, Deputy Head of Mission and First Secretary of the German Embassy and Mr. Acharya, Director General of the Department of Water Supply and Sewerage (DWSS) for the opening remarks.

Mr. Pahari (UNICEF) and Mr. Neupane (DWSS) gave an overview on the arsenic investigation and implementation of mitigation methods in Nepal. The presentation did not only illustrate the various co-operations in the field of arsenic mitigation, but also gave a valid review of current problems concerning this topic. The second presentation was given by Mr. Regmi (Department of Local Infrastructure Development and Agricultural Roads – Ministry of Local Development). He represented the Rural Water Supply and Sanitation Project in West Nepal (RWSSP-WN), supported by the Finnish and Nepalese Government.

Professor Dr. Sharma (University of Kathmandu) presented his research on the problem of arsenic water contamination worldwide and especially in Nepal. Mr. Maharjan (ENPHO), explained the successes and failures of various mitigation methods regarding arsenic removal, which were implemented in various Terai districts of Nepal. Associate Professor Dr. Shrestha (Tribhuvan University Kathmandu) held a presentation on the seasonal arsenic variations in the groundwater of Nepal. Ms. Diwakar (HEMS), presented methods developed by scientists of the Department for Hydrogeology and Environmental Geology of the MLU Halle-Wittenberg for improving groundwater monitoring strategies and led over to the final presentation – the presentation of the ARSOlux biosensor.

Mrs. Hahn-Tomer and Dr. Siegfried gave an overview of the project and explained the handling and technical details of the ARSOlux biosensor. The audience listened with great interest and did not only ask questions but also gave suggestions on how to implement the biosensor locally.
