KeyNote : Micropollutants loads in the road runoff - importance, nature and efficiency of runoff source control measures
Abstract
Runoff from trafficked area is recognized as a significant pathway of micropollutants, contributing to non-point source pollution of surface waters. Sources and fluxes of trace metal and hydrocarbon associated to road runoff have been widely documented, however recent studies also put forward a complex matrix of other organic and mineral micropollutants.
The presentation summarises knowledge gained over recent years from the Roulépur project, and other projects associated to the OPUR observatory of urban hydrology, in Paris region. Funded by the French Agency for Biodiversity and Seine-Normandie Water Agency, Roulépur aimed at a better characterisation of road and parking lot runoff, as well as the evaluation of a range of runoff source control measures. It is based on field monitoring on four sites with contrasted contexts and traffic levels, and four types of runoff control measures ranging from nature based to more technological. Operational recommendations are given based on a holistic evaluation, including targeted and non-targeted screening for a broad range of pollutants, treatment performance assessment, hydrological analysis as well as socio-technical and lifecycle analysis.
