Context
- Runoff from roadways and parking lots
- A complex matrix of micropollutants
- Need for source control / treatment
- Necessity to adapt the solutions to site specifics
Objectives
- 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)
Ecovégétal
- Non-infiltrating horizontal planted filters (CG93 – Rosny sous Bois)

Methodology
- 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
- Diagnosis of road runoff contamination
Tasks
- 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
