  • Runoff from roadways and parking lots
  • A complex matrix of micropollutants
  • Need for source control / treatment
  • Necessity to adapt the solutions to site specifics


  • Diagnose the composition and toxicity of runoff water, identifying primary sources
  • Evaluate several innovative treatment solutions in situ in terms of efficiency (hydrology, chemistry and ecotoxicity) and sustainability (maintenance, aging)
  • Analyse the overall environmental performance through a life cycle assessment (LCA)
  • Assess solutions’ ownership conditions (social, technical and economic) and diffusion potential within the local context

Study sites

  • 4 sites in Paris conurbation
  • Contrasted pollution levels and urban contexts
  • 4 treatment facilities
    • Both nature-based and technological devices
    • Vegetative filter strip and biofiltration swale
    • Pervious, vegetated car park
    • Small, horizontal sand filter
    • Compact settling / filtration / adsorption device
  • Permeable filtering parking developped by Ecovégétal (Broué et Villeneuve le Roi)
  • Non-infiltrating horizontal planted filters (CG93 – Rosny sous Bois)
    Marie-Christine Gromaire, LEESU, Ecole des ponts ParisTech
  • Vegetated shoulders + filtering / infiltrating ditches (CG77 – RD212 Compans)
    Marie-Christine Gromaire, LEESU, Ecole des ponts ParisTech
  • Compact decantation / filtration / adsorption device from STOPPOL 10CKF (Ville de Paris, voie George Pompidou)
    Saint-Dizier Environnement


  • A holistic and multidisciplinary approach
  • Micropollutants studied
    • Diagnosis of road runoff contamination
      • Targeted screening: PBDE, DEHP, organotins, nickel, HBCDD, PFOS, benzotriazoles, tetrabromobisphenol A, platinoïdes
      • Non targeted screening
    • Performance evaluation of facilities
      • SS, POC, DOC, N, P, major ions, Hydrocarbons
      • Micropolluants: 12 metals, PAH, alkylphenols, bisphenolA, phtalates
      • Toxicity analysis


  • T1. Assessment methodologies of management systems
  • T2. Monitor water composition and toxicity - Identify primary sources
  • T3. Evaluate in-situ the effectiveness of several innovative treatment solutions of different technicalities (hydrology, chemistry and ecotox)
  • T4. Analyze the global environmental performance (LCA) and the sustainability (maintenance, aging) of these solutions
  • T5.Evaluate social and technical acceptability, cost, potential for diffusion of solutions
  • T6. Valorisation and transfer of results
