Résumé

Many studies have analysed and quantified stormwater runoff polluting impact in water bodies. In the meantime municipalities encourage the use of stormwater control measures (SCM) to reduce waterflows and pollutant contamination. In this context, the Micromegas project aims at i) determining how to evaluate the efficiency of SCMs regarding micropollutant (MP) removal and ii) comparing the efficiency of centralized "end of pipes" SCMs versus source control systems. Their efficiency is determined through in-situ sampling, the quantification of 54 MP and the comparison of concentration loads at the outlet of a retention basin (centralized system) and three source control systems (a swale, a trench and a porous pavement) with respectively water from the supplying pipe network and the outlet of a similar impervious asphalted site. This article presents our first results regarding these four sites efficiency as well as the monitoring and sampling procedures and the comparison methodology.
