All these factors induce high pressures on water resources both on quantity and quality in the context of global social and environmental changes. This paper focuses on the groundwater geochemistry in a costal multilayer aquifer aiming at investigating the sources and processes of salinization. The preliminary results of 62 groundwater samples from the five main aquifers are reported. %G English %Z COQUEIRAL %2 https://brgm.hal.science/hal-00772976/document %2 https://brgm.hal.science/hal-00772976/file/WRI_-_Hal.pdf %L hal-00772976 %U https://brgm.hal.science/hal-00772976 %~ SDE %~ INSU %~ BRGM %~ UNIV-RENNES1 %~ UR2-HB %~ CNRS %~ GR %~ OSUR %~ GIP-BE %~ UR1-HAL %~ UR1-SDLM %~ GR-DIMENV %~ UNIV-RENNES2 %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INRAE %~ UR1-ENV %~ GR-ET
