Research laboratories

The research of the Leesu unit focuses, above all, on urban water, through different approaches:
• Physical and hydrological studies (runoff, transfer in the urban system, lake environments),
• Biogeochemical studies of emissions, and of the fate and effects of chemical and microbiological contaminants in the town/hydraulic facility/reservoir environment continuum,
• Studies of policy, water use and practices, and their changes.
The Leesu unit performs complete multi- and interdisciplinary studies, with a high degree of commitment, which is essential for pertinent studies in the environment. Its research work relates to major societal issues, such as the development of sustainable towns resilient in the face of change, the optimization of water resources, the protection of underground water and aquatic ecosystems. The activities of the Leesu unit are anchored in long-standing close partnerships with town councils in the Parisian region and actors in water domain. 

The work of the unit is built around four research axes:

• Sources and outcome of urban water contamination
• Study of policy and water use and their changes in the urban environment
• The urban cycle and rainwater
• Impact of the town on the functioning of aquatic environments (lakes and urban bodies of water)
