The energy transition is associated with the increasing use of a wide range of metals, particularly those needed for lithium-ion batteries (e.g. lithium, cobalt), while there is a continuing need for base metals (e.g. copper, zinc). The development of alternative metal resources such as "liquid ores", notably the formation waters of sedimentary basin aquifers, could potentially contribute to meeting global demand. However, the geochemical processes involved in metal enrichment in formation waters remain poorly understood and the following approach was therefore pursued in this work: • Establishment of a database of temperatures and chemical and isotopic compositions of formation waters (3700 analyses) and fluid inclusions that preserved ancient formation waters (1700 analyses) from 90 sedimentary basins worldwide, based on published sources. The objective is to highlight the characteristic concentration ranges of dissolved metals in formation waters and the parameters that control their concentration. • Application to the case study of the Rhine Graben, on the example of the Soultz-sous-Forêts geothermal system, through the analysis of metals in fluid inclusions and minerals of the basin and the crystalline basement. The aim is to provide an overview of metal transfers related to fluid-rock interactions from the Oligocene to Present. The results indicate that formation waters generally acquire their metal load (Li, Mn, Pb, Zn, Fe, Ba, Cu) mainly through fluid-rock interactions, the increase in temperature and salinity facilitating their dissolution. In the peculiar case of lithium, the richest formation waters are most often brines derived from seawater and enriched in salts and partially in lithium by surface evaporation, and subsequently expelled from the evaporitic formations in which they are initially trapped, during tectonic events. The preservation from dilution by recharge fluids, and the interaction with lithologies enriched in lithium (siliciclastic rocks, volcanic levels, crystalline basement) are two key parameters to reach the highest concentrations. The lithium resources estimated in some reservoirs are of the same order of magnitude as those of the salars and hard-rock mines (granites, pegmatites) currently exploited. In the case of the Rhine Graben, brines from the Triassic formations mix with more diluted waters infiltrated from the Vosges mountains, and carry significant amounts of lithium (up to 200 mg.l⁻¹ in the present-day formation waters) as well as other metals (e.g. Pb, Zn, Cu, As, Sb). Fluid inclusions show that lithium concentrations from 3 to 800 ppm of lithium were reached between the Oligocene and Present. Mineral analysis indicates that the main Li carriers (Fe, Mn, Zn) in the crystalline basement are biotite, amphibole and chlorite, which were probably significant sources for these metals

The first theme has for objectives: 1) to trace the origin of the salinity of the waters of the karst aquifers in coastal environment mediterraneen,2) to quantify the mixing proportions between salt waters and the waters karstiques,3) to discriminate the geochemical tracers to identify and model the process of salinization of aquifers coastal karst. The second theme has for objectives:1) to establish the [hast] of natural origin of surface waters and groundwater, 2) to quantify the level of contamination by arsenic in these waters and its spatial and temporal variability 3) to trace the natural or anthropogenic origin of pollution in hast to the aid of isotopic tools adapted. the origins of the salinity identified include i) of came from deep waters salted ii) of come deep water salted dating back toward the surface by a major flaw normal. The 36Cl/Cl has allowed us to identify the origin of deep saline waters and a recharge of meteoric water infiltrated during the period of thermonuclear tests. The PHREEQC modeling used to differentiate between the mixture with a deep water of salt that one with a sea water current. The 87SR/ 86Sr shows a conservative behavior for tracing the origin of saline waters in karst aquifers. The plotters Cs, Rb, Li and B allows to differentiate the three origins identified of salinity. The data acquired on the contamination in hast underline a net increase and perennial of [hast] from the ancient sites of mining processing rehabilitated. The reports 87SR/ 86Sr and δ18O and δ2H will reveal in this case a chartplotter very discriminant of natural or anthropogenic origin of arsenic

The 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

In agricultural areas, the pollution of aquifers by nitrates is caused especially by the mineralization of soil organic matter. This phenomenon is aggravated by farming practices that use organic or mineral fertilizers to achieve maximum yield. During five years, the nitrate levels in top-soil layer (Ap and subsequent lavers) of a clayey-calcareous soil were measured. The amounts of these nitrates non immobilized by soil or by crops come directly to a mini-watersheb supplying a water-catchment of the commune of Loisy (54). The nitrate contents of water were, for several years beyond the target content of 50 mg/l (CEE norm) to range between 65 and 75 mg/l. Therefore, an attempt was made to explain the relationship between the contents of nitrates in soil and in drainage water measured weekly. In parallel, the influence of the buryinf of the straw and an intercrop culture using rape to catch the nitrates was studied during the intercrop period on bare soil. The overall balance of this work explained clearly the necessity to know the real supply of native mineral nitrogen. Nitrogen fertilizers applications should be made accounting for local climatic conditions and particularly the different stages of the development of plant crop

The biogeochemical cycle of trace metals was greatly accelerated by human activities that have led to the contamination of water and river sediments. Following their emissions, the majority of trace metals exist in particulate form which can be transported by runoff and end up in rivers where they settle and where a portion can be dissolved into the water column in response to changes in the physico-chemical conditions of the site and under the action of indigenous microorganisms which later can interact with the food chain and pose a potential danger of toxicity to humans and other living organisms. In this study, we have chosen to work on Al-Ghadir River which represents an exceptional and an original case of pollution where the height of sediments, including several types of pollutants, is more than one meter. The aim of this work was to understand and to evaluate the role of the microbial compartment in the sediments of the Al-Ghadir River, which is the most polluting source to the Mediterranean, on the mobility of metals and their effects on underground water. This study was realized in two series of experiments (batch and soil column) with situations similar to those found in the river. A physico-chemical and chemical characterization of the studied sites was conducted as a first step to begin, after that, with the experimental approach which was used to isolate the physico-chemical processes from those which are attributable to microbiological activity. In the experiments conducted in closed reactors (batch), results obtained showed that the microbial activities are correlated with the strong dissolution of metals, especially for Fe, Mn, Pb, Cu and Zn. Iron appeared the most solubilized element and its solubilisation was correlated with the other trace metals suggesting that these metals are associated to iron oxides. This hypothesis was confirmed by sequential extraction procedure indicating the presence of iron-reducing bacteria, which, during the fermentation of glucose and the production of organic acids, reduced iron oxides. These later have led to the dissolution of trace metals and to a change in the bacterial populations which were detected after five days of incubation by the microbiological and the genetic studies. The effect of the bacteria on the mobilization of metals in sediments was then studied in hydrodynamic columns, under conditions similar to those in the field. Results obtained showed that: (i) Studied metals are not leached in the same order and showed the following order (in μg/l): Fe > Mn > Cd > Zn > Cu > Pb ≥ Cr; (ii) Metals will reprecipitate on the neoformed phases after the system returns to equilibrium. Studies of the distribution profile of metals in columns showed that metals were leached homogenously from the sediments during incubation. This distribution was shown to depend on the height of the sediment where the re-distribution was shown at its maximum at the surface of the column sediments (0-10 cm) and became null at a depth between 10 and 25 cm. This phenomenon is explained by the fact that the metals after being dissolved and passed into solution, were then readsorbed to the negative electrochemical, neoformed and colloidal sediment phases which explains the decrease in the concentration of metals in the leachate obtained in the laboratory and suggests that the mechanism of trapping of metals in the column limits the migration of these later to underground water, as the adsorption capacity of present colloïds is not reached and the system is at equilibrium

It is now, well recognized that agricultural activities are responsible for an important part of the groundwater nitrate pollution. The case of the alluvial plains is particularly interesting because they associate the presence of a rich and deep soil, very favourable to the agriculture, and shallow alluvial groundwater. In this work we are interested in two types of alluvial plain. The alluvial plain of the Alegria River (Pays-Basque, Spain) represent the case of an alluvial plain with a small river. The recharge of the aquifer is mainly made by the infiltration and the percolation of the water through the not saturated zone of the soil. In such situation the nitrate leaching under the agricultural plots influences significantly the groundwater nitrate concentrations. The modelling of two crops (a potato crop in 1993 and a sugar beet crop in 2002) with the model the STICS soil-crop allowed on one hand to confirm that the agricultural practices had a significant impact on the evolution of the groundwater nitrate concentrations, and on the other hand to explain partially the decrease of the concentrations which was observed between the studies (between 1993 and 2002). The alluvial plain of the Garonne corresponds to a situation where the groundwater solutes concentrations are influenced by the exchanges between not saturated zone and the groundwater but also by the exchanges between groundwater and river. The coupling of the STICS model outputs (drainage and concentration in nitrate) with the hydro-biogeochemical model 2SWEM allowed to simulate these two types of interactions, and so, on one hand to explain the spatial distribution of the groundwater nitrate concentrations, and on the other hand to estimate the impact of modifications of the agricultural practices on these concentrations (notably the effect of the catch crop)
