Project summary :

The DIADeM project (Development of an Integrated Approach for the Diagnosis of Water Quality in the Meuse), coordinated at URCA by Alain Geffard (SEBIO), falls under Axis 3 of the programme (environment).

The partners are: University of Namur, University of Liège/Arlon, INERIS, Société wallone des eaux, IRSTEA, CER Groupe, EPAMA-EPTB Meuse. The associated actors are: Société Publique de la Gestion de l'Eau, ACCUSTICA, Agence de l'Eau Rhin Meuse, Contrat de Rivière Semois-Chiers, Contrat de Rivière Haute-Meuse, Contrat de Rivière Sambre et Affluents, Ardenne Métropole.

Summary: The importance of the ecosystem services rendered by the natural volumes of water leads to a significant social expectation with regard to maintaining their quality. These environments collect a large number of contaminants resulting from human activities, including one significant, chronic source taking the form of waste from water treatment plants, and particularly as so-called emerging molecules, the impact of which on these environments is not well known. The shared use of the water resources from the Meuse basin on both sides of the Belgian border requires coherent, joint management.

The DIADeM project thus proposes to develop and deploy an interdisciplinary, cross-border approach in order to improve the diagnosis and monitoring of the chemical quality of the water in the Meuse (from Sedan to Namur) and two tributaries (Semois and Haute-Sambre). To achieve this objective, the DIADeM project is broken down into 6 working modules (WM) to develop awareness of the contamination of bodies of water, in connection with the presence of water treatment plant waste, and the identification of the associated biological effects. The unique project proposes bringing together chemical and biological analyses (biomarkers) carried out on enclosed organisms of species representative of cross-border hydrosystems and mathematical models to predict the effect at a population level.

All the knowledge will be transferred to the interregional population in various formats. A first facet will concern stakeholders, with management assistance tools. A second facet will address students for training purposes and the general public, raising awareness of the issues of water contamination and the protection of resources. The progress made by the DIADeM project will help protect and enhance the environment through the integrated management of cross-border resources, but also the establishment of more respectful, responsible behaviour in a move towards the sustainable use of resources.

Role of the CER :

The objective of the CER is evaluating the bioconcentration factor and / or bioaccumulation of contaminants in water by their dosage in the tissues of living organisms.

The CER will perform the chemical analyses from the tissues of organisms exposed to these emerging contaminants on the basis of a well-controlled UHPLC-MS / MS methodology.

These analyzes will be carried out, on one hand, on the organisms exposed in artificial rivers (activity 1 MT5) and, on the other hand, on organisms caged on the various study sites (activity 2 MT4).

An important result will be to confirm the accumulation capacity of these molecules within the biota and to identify, on the basis of the interspecific differences (metabolisation or not of the molecules), the species or the most appropriate species to translate/express the contamination of water.

These results will be integrated into a database summarizing all the information obtained on the study area.

Calendar of the activity: 12-30 months.
