Concawe has published a new report called Case Studies
and Analysis of Sustainable Remediation Techniques
and Technologies
The report aims to fill in a recognised gap in the provision of detailed case studies documenting the practical implementation of sustainable remediation, 
and facilitate further refinement of guidance. Concawe commissioned CL:AIRE to a) gather, prepare and publish ten European case studies that demonstrate
sustainable remediation techniques and technologies and b) provide an analysis of the case studies to identify key success factors. A cross-comparison analysis
of the ten case studies has been carried out, seeking to help practitioners compare these case studies to their own projects. The cross-comparison analysis
focused on the following attributes: site location and type of site (former use); saturated / unsaturated zone impact; targeted contaminants; risk drivers;
envisaged land use; objectives for sustainability assessment; remediation options compared; stakeholder engagement; boundary conditions; scope (environmental,
economic, social); key constraints / opportunities; and assessment type (qualitative, semi-quantitative etc). Based on this analysis and recently published
guidance, a practical approach for deploying sustainable remediation on operational sites has been proposed. Working with a risk-based conceptual site
model, effective engagement with stakeholders and a sound understanding of sustainable remediation practices are seen as key success factors from these
case studies. The report was prepared by Rob Sweeney and Nicola Harries, CL:AIRE and Paul Bardos, r3 Environmental Technology Ltd. The report is available to download on the Concawe website at and ten CL:AIRE Concawe Case Study Bulletins are available to download individually
