Research Group on Water, Soil and the Environment (GRESE)
EA 4330

The Research Group on Water, Soil and the Environment (GRESE) federates 40 permanent teacher-researchers and technicians and 20 doctoral students in the field of Environmental Sciences, which include in particular specialists in analytical chemistry, process engineering, physico-chemistry, solid-state chemistry, pedology, surface geoscience, ecology and botany. Research focuses on two complementary areas : • liquid phase and solid phase chemical speciation for assessing the transfer conditions of organic and inorganic pollution on the surface of the Earth, • the development of technological responses and implementation of innovative processes and management modes for treating polluted water and soils. These themes are addressed from a fundamental viewpoint by studying the mechanisms of genesis, chemical speciation, interactions between phases and degradation of pollutants. A wide variety of mediums are studied including soils, sediments and solid residues, water, plants and purifying biomass. The GRESE’s research is applied to assessing risks related to point and non-point, metal and organic pollution (mine waste heaps, industrial sites, use of pesticides, etc.) and specific liquid discharges (hospital, urban effluents, etc.). The GRESE also develops processes for treating water and waste and for rehabilitating, upgrading and decontaminating industrial sites. The GRESE is involved in national and European networks and develops many partnerships with Southern countries and with Eastern European countries where there are major environmental issues. Finally, the GRESE has been partnering for many years with companies, public establishments and institutions in the field
