Marie Vahter (1950) holds a PhD from Karolinska Institutet, Stockholm, Sweden, and is since 1987 Professor at the Institute of Environmental Medicine at Karolinska Institutet . Her research concerns mainly toxic metals and human health in a wide sense; from exposure and related health effects, to the underlying toxic mechanisms and various susceptibility factors. Currently the research focuses on the health effects of early-life exposure and involves several mother-child cohorts. Professor Vahter is a highly productive (more than 300 publications and 11000 citations) and internationally recognized researcher of associations between exposure and the impact of metals on human health on a global level. She has participated in several risk assessments of toxic metals. Among other things, she has contributed to a reduction of limit values for arsenic in drinking water for the majority of countries in the world.

The projects relate to groundwater contamination related to: i) occurrence and behavior of pesticides in groundwater (within the Pegasus project), ii) arsenic contamination of drinking water resources (within the Amonas project), iii) age determination and mixing of groundwater and its relationship to contaminants (within a Region Skåne/SGU-financed project) and iv) Trust-project (Transparent Underground Structures) concerning "Geoelectrical Imaging for Site Investigation of Urban Underground Infrastructure".

Gunnar Jacks (1937) graduated as mining engineer from KTH Royal Institute of Technology in 1962. After working with rock stability issues for a couple of years he spent a year with a humanitarian NGO in Turkey where he realized the importance of water for societies and human life. He took a B Sc. degree in Medicine from the Karolinska Institute in 1971. After returning to Sweden and KTH, he studied hydrology and received the PhD in hydrochemistry in 1973. He assisted his professor in a short term groundwater investigation in Tamil Nadu in India, which led to a three year project work within Central Ground Water Board in Coimbatore in India and later on to an engagement in a project in Kerala. Excess fluoride in groundwater was a major interest in his and his Indian colleagues work. While he has throughout years been a faculty member at KTH he has been on missions to Botswana, Vietnam, Thailand, and Laos. Acid mine drainage has from the mid 1970-s been part of his interest. He was the head of the Groundwater Chemistry Group of the former Division of Land and Water Resources, Department of Civil and Environmental Engineering of the KTH and took active part in the research regarding acid deposition during the 1980-s and 1990-s. The quantitative study of weathering rates became an important issue and he was part of a group that used strontium isotopes for assessments. He has been involved with a number of international research projects since 1990s which include investigation on high fluoride groundwater in Rajasthan (1994-1997). He has been actively involved in research on arsenic in soil and groundwater systems since 1991. During 1996, the his research group at KTH was contacted by Dr. Debashis Chatterjee from Kalyani University in Kolkata, India regarding the arsenic problems in West Bengal. That was the start of a still ongoing work in India, Bangladesh and several other parts of the world with a principal focus on research on the mechanisms of arsenic mobilisation in groundwater environments. Gunnar Jacks has also in recent years been working on zinc deficiency in soils in the Niger inland delta in Mali. He is a guest Professor at Åbo Akademi, the Swedish speaking university in Finland. In 2006, he was elected as the President of the International Society of Groundwater for Sustainable Development (ISGSD).

Ravi Naidu is the CEO and Managing Director of the Cooperative Research Centre for Contamination Assessment and Remediation of the Environment (CRC CARE), Professor and Global Innovation Chair and Director of the Global Centre for Environmental Remediation at the University of Newcastle, Australia. Prof. Naidu’s work focuses on the remediation of contaminated soil, water and air, and the potential impacts of contaminants upon environmental and human health at local, national and global levels. Prof. Naidu been a global leader in the move to the now widely accepted ‘risk-based’ approach to managing contaminated sites. He has also been a leader in the shift to in situ remediation – cleaning up contamination where it lies, rather than the traditional ‘dig and dump’ approach. Together, these approaches potentially save industry millions, if not billions, of dollars annually and make clean-up far more feasible and effective. Prof. Naidu received his PhD in environmental science from Massey University, New Zealand. He is an elected Fellow of the Soil Science Societies of America (2000) and New Zealand (2004), and the America Society of Agronomy (2006), and was the founding director of the University of South Australia’s Centre for Environmental Risk Assessment and Remediation. In 2013 was elected a Fellow of the American Association for the Advancement of Science. He is Chair of the International Committee on Bioavailability and Risk Assessment, former Chair of the International Union of Soil Sciences Commission for Soil Degradation Control, Remediation and Reclamation (2002-10), and former President of the International Society on Trace Element Biogeochemistry (2005-07). He has authored or co-authored over 420 journal articles and 80 technical publications as well as seven patents, and co-edited 11 books and over 66 book chapters in the field of soil and environmental sciences. He has also supervised over 30 PhD completions. In 2013, Professor Naidu received an honorary Doctorate of Science from Tamil Nadu Agricultural University for "outstanding contributions to agriculture", and won the Richard Pratt – Banksia CEO Award at the Banksia Sustainability Awards, recognizing his contributions towards environmental sustainability.
