The fifth ADVOCATE network training workshop on the theme of Soil and groundwater remediation : sustainable management strategies, effective clean-up methods and emerging contaminants was hosted at AGH University of Science and Technology in Krakow, Poland, on 16/17 May 2013. The workshop was attended by 15 fellows and external participants, who included researchers, consultants and other professionals. Over the two days the participants were introduced to the principles and practical application of sustainable management strategies for soil and groundwater. Topics covered the management of soil and groundwater contamination at former military airports, numerical modelling as a tool for remediation design, in situ remediation of contaminated fractured soils and an overview of the development and use of conceptual site models for site management. On the second day, participants collaborated ingroup-based exercises where each team developed a conceptual site model from a case study, to support decision-making on risk assessment and remediation design. The analysis considered the definition of appropriate site characterisation objectives and data needs, the selection of relevant laboratory and pilot-scale tests to provide additional information, and possible scenarios for numerical modelling. Each team then presented their interpretation and recommendations to the workshop for discussion. The workshop was presented by researchers from AGH University of Science and Technology, the University of Sheffield and ADVOCATE associate partner Hydrogeotechnika Ltd, and guest speakers from IETU Katowice and DWL Warsaw.
