Full textIn France, groundwater supports 65% of the drinking water supply. The increasing pressures of human activities lead to water pollution and the closure of water supply wells. The diversity of existing pollutants and the emergence of new contaminants require a comprehensive understanding of the functioning of groundwater bodies. The implementation of action plans by local authorities and resource managers requires identifying the origins of contaminants and defining vulnerable areas with precision. The objective of this work is to establish a multi-tracer approach on the Vistrenque aquifer (France, Gard), to study the origin and transfer of contaminants. Analyses include natural tracers of water origin (major, minor, and trace elements), stable isotopes of water molecules (δ18O/δ2H-H2O), stable nitrogen isotopes of nitrates δ15N/δ18O-NO3-, boron isotope δ11B, gadolinium (Gd), as well as a range of organic molecules including pesticides and pharmaceutical residues, serving as tracers themselves. Using this multi-tracer approach, it was possible to identify the origin of nitrates in water catchment areas where agricultural and urban nitrate sources overlap. Analysis of the isotopic signature in δ15N/δ18O-NO3- of easily mobilized nitrates in soils has proved to be an effective tool for characterizing nitrogen pollution in an agricultural context. The land parcels responsible for contamination were identified, based on the comparison of the isotopic signatures of soils and groundwater. In addition to agricultural contamination, the infiltration of an urban effluent plume from a wastewater treatment plant into the aquifer highlighted the importance of studying the occurrence of pharmaceutical residues and the vulnerability of aquifers to emerging contaminants. All these observations have laid the groundwork for extending this approach to other study areas, focusing on the operability of the geochemical, isotopic, and organic multi-tracer approach

Full textThe pollution of waters by the nitrates can have three origins: agricultural, industrial, domestic. It results from a main process, the mineralization of organic nitrogen, that is to say its transformation in soluble nitrogen. Because of different agents (climate, vegetation, etc) the nitrates are more or less drawled away to the phreatic sheets. In Lorraine, the analyses of underground waters show the irregular but general progression of the nitrates between 1976 and 1989. The examination of polluted areas will allow us to estimate the part of physical factor ( prheatic sheets vulnerability) and human factor ( nitrogenous throw ) in pollution phenomena

Full textSainte Baume (Bouches du Rhône, Var ; France) is the most southern massif of lower carbonated Provence. Its structure results from resumption of south provencal overthrust by the tectonic major ponto-pilocene phase. Its complex geologic structures are cut at right angle by a fluviatile drainage s. N. This disposition determines a partition of underground drainage. Total outflow goes up to eight hundred litres per second and mean of major springs are modest. This massif includes all types of function as defined by A. Mangin. It is drained on three levels and according to three axes: n. Towards local springs; towards the oriental and occidental lower spring; towards sub-marine springs. Hydrochemical and bacteriological analyses show that these waters are of great quality. A relation between the springs altitude and the value of the exhaustion coefficient proves that underground and areal drainage cannot be dissociated. Morphological studies of fluviatile river basins show that their main dimensions are linked. As underground drainage cannot be analysed by a morphological study we have developed a more theoretical approach resting on the principles developed by thermodynamics of irreversible phenomena. Drainage structures thus have coherence which must guide all reconstitution: Sainte Baume which has undergone many changes in drainage orientation is an old karst. Ancient morphology continues to play a part in the actual hydrological function as this karst have never been subjected to major upheavals which would have excluded these ancient structures from the drainage pattern

Full textContamination study of agricultural nitrate in haut-rhone aquifer requires an evident multidisciplinarity approach in view of the important number of factors involved in this mechanism. Nitrate in groundwater usually results ofrom the combination of many climatic, agronomic, hydrological, hydrogeological and geological factors. The different situations come across, usually result from the importance of each factor. Such a study allows to determine the vulnerability of agricultural nitate contamination of each aquifer
