New approaches for low-invasive contaminated site characterization, monitoring and modelling

摘要: Previously, conventional techniques for characterizing contaminated sites were often applied with limited strategic planning, resulting in time-consuming and costintensive investigation campaigns, which did not effectively support decision-making. The need remediation, the optimal way of doing so terms environmental beneficial effect cost effectiveness, involves problem owners, authorities, consultants. Each these stakeholders has to deal lack knowledge broad-bands uncertainty regarding subsurface contaminant distribution processes. primary cause is spatiotemporal variability both subsurface, its structure processes such as flow, transport, biodegradation, pollution event. This leads highly erratic patterns concentrations, cannot be captured experimentally that provide point measurements. An obvious solution ‘invisible subsoil’ develop new ways monitoring. this innovation was identified by US EPA European Commission, based on step-by-step site characterization strategies, allowing smart feedback loops (Fig. 1). needs laid down a call FP 7 program then acted starting overall project approaches. research presented special issue centred around two Commission Framework projects: ‘ModelPROBE Model-driven Soil Probing, Site Assessment Evaluation’ (Grant agreement No. 213161; www.modelprobe.eu ) much higher extent, ‘SoilCAM – Contamination: Advanced Integrated Characterisation Time Lapse Monitoring’ 212663; www.soilcam.eu ). activities dedicated development emerging methods and, equally important, improvement combination previously developed methods, interdisciplinary efforts investigation, assessment sites. Negotiations started 2008, led establishment collaboration links between projects selected competitive proposals within Technology topic, order make use possibly synergistic approaches ensure transfer projects. overlap personnel partners consortia facilitated collaboration. cluster Research, coalition funded Responsible editor: Philippe Garrigues
