“…This reasoning is also coherent if part of these brines originates from the dissolution of evaporites. Indeed, waters draining evaporites present usually very high ( 234 U/ 238 U) values (Riotte et al, 1999;Durand et al, 2005;Lucas et al, 2010).…”

“…The code KIRMAT solves the geochemical reaction and transport mass balance equations in a saturated porous medium. A description of its functionalities can be found in Lucas et al (2010). Lastly, a few spring and borehole samples from the Strengbach catchment have been collected for groundwater dating by the analysis of anthropogenic gases (CFC, SF6), following the techniques detailed in Labasque et al (2014).…”

From the study of the Strengbach and Ringelbach watersheds we propose to illustrate the interest of combining the geochemical tracing and geochemical modeling approaches on surface and deep borehole waters, to decipher the diversity of the water flow and the associated water-rock interactions in such elementary mountainous catchments. The results point to a clear geochemical typology of waters depending on the water circulations (deep vs. hypodermic) within the substratum.

“…marine or estuarine water recharged during past transgressions, which have usually evolved through mixing with freshwater, water-rock interaction or after evaporation in lagoons (Aquilina et al, 2002(Aquilina et al, , 2013Armandine Les Landes et al, 2014;Duriez et al, 2008;Edmunds and Milne, 2001;Han et al, 2011;Khaska et al, 2013;Négrel and Casanova, 2005;Sola et al, 2014;Vengosh et al, 2005Vengosh et al, , 1999. Other sources of salinity are dissolution of evaporites with or without further water-rock interactions (Cendón et al, 2008;Kloppmann et al, 2001;Lucas et al, 2010;Merchán et al, 2015;Mongelli et al, 2013), evaporation of freshwater, notably when used for irrigation, pollution by untreated wastewater (Cary et al, 2013;Giménez Forcada and Morell Evangelista, 2008), and return flow (Cruz-Fuentes et al, 2014;Perrin et al, 2011). As these processes are not necessarily exclusive, defining the origin of salinization might thus remain highly complex (Chaudhuri and Ale, 2014).…”

In the coastal multilayer aquifer system of a highly urbanized southern city (Recife, Brazil), where groundwaters are affected by salinization, a multi-isotope approach (Sr, B, O, H) was used to investigate the sources and processes of salinization. The high diversity of the geological bodies, built since the Atlantic opening during the Cretaceous, highly constrains the heterogeneity of the groundwater chemistry, e.g. Sr isotope ratios, and needs to be integrated to explain the salinization processes and groundwater pathways. A paleoseawater intrusion, most probably the 120 kyB.P. Pleistocene marine transgression, and cationic exchange are clearly evidenced in the most salinized parts of the Cabo and Beberibe aquifers. All (87)Sr/(86)Sr values are above the past and present-day seawater signatures, meaning that the Sr isotopic signature is altered due to additional Sr inputs from dilution with different freshwaters, and water-rock interactions. Only the Cabo aquifer presents a well-delimitated area of Na-HCO3 water typical of a freshening process. The two deep aquifers also display a broad range of B concentrations and B isotope ratios with values among the highest known to date (63-68.5‰). This suggests multiple sources and processes affecting B behavior, among which mixing with saline water, B sorption on clays and mixing with wastewater. The highly fractionated B isotopic values were explained by infiltration of relatively salty water with B interacting with clays, pointing out the major role played by (palaeo)-channels for the deep Beberibe aquifer recharge. Based on an increase of salinity at the end of the dry season, a present-day seawater intrusion is identified in the surficial Boa Viagem aquifer. Our conceptual model presents a comprehensive understanding of the major groundwater salinization pathways and processes, and should be of benefit for other southern Atlantic coastal aquifers to better address groundwater management issues.
