Das Projekt "Konzertierte Aktion zur Risikoabschaetzung fuer kontaminierte Flaechen" wird vom Umweltbundesamt gefördert und von Max-Planck-Institut für Meteorologie durchgeführt. The concerted action will concentrate on the coordination of research activities on risk assessment for contaminated land within Europe and will develop recommendations and guidelines based on the current state of knowledge. The general technical approach to achieve these goals will be as follows: 1) Identification and synopsis of respective RTD (Research and Technical Development) projects in the Member Sates, 2) Identification and compilation of relevant RTD projects funded by the European Commission under the 'Environment and Climate' programme and other specific programmes. Exchange of information and results with the Scientific Committee of the present EU study 'Comparative study on the different national approaches of risk assessment and remedial investigation at a contaminated site', 3) Assessment, review and discussion of the objectives and the results achieved of the above-mentioned RTD projects. Evaluation of the different guidelines for comparative risk assessment, for detailed risk assessment, for setting priorities and technical instruments and scientific tools, 4) Compilation of all project information and drawing up of a status report about RTD projects of risk assessment in the European Union, 5) Identification of future R and D priorities on risk assessment of contaminated land, 6) Preparation of a final recommendation and information report for the European Commission and the EU Member States, 7) Elaboration of a draft for recommendations or guidelines for risk assessment of contaminated land.
