ROULÉPUR: Evaluating innovative solutions for the source control of micropollutants associated with road and parking lot runoff

The ROULÉPUR project, funded under the French national call "Innovation and changes in practice: fighting against micropollutants in urban waters", aims at evaluating innovative solutions for the source control of micropollutants in road runoff, based on a multidisciplinary approach. It’s objectives are to: improve knowledge on the chemical composition and toxicity of road and parking lot runoff; identify the primary sources of contamination, so as to guide emission reduction strategies; evaluate in situ the effectiveness of four innovative source control solutions of different technicalities; analyze the overall environmental performance of these solutions on the whole its life cycle (LCA); assess the social, technical and economic acceptability of these solutions and deduce their diffusion potential based on the technical and institutional local context. Four different source control solutions are tested in situ: pervious car park, horizontal sand filters, vegetated filter strips and bioretention swales, and a compact sedimentation / filtration / adsorption device.
