The project is structured around 2 main objectives:1- to develop new methods of analysis of trace micropollutants and to be able to monitor their evolution in the natural environment. Experimental data will be provided on the quality of the resource and the level of pollution. This data will provide innovative technological solutions for water remediation and treatment.2- develop simulation models to better understand the interactions between pollutants and the environment (water or soil). This knowledge of the environment (air, water, soil) makes it possible to propose technological solutions for the treatment and remediation of water.
