The Santo Domingo-Salinas ranges represent the south-westernmost termination of the Pyrenean sole thrust separating the Pyrenees from the Ebro foreland basin to the South. The Santo Domingo anticline is the main structural feature in the area (Oliva-Urcia et al., 2012). This area practically lacks of hydrogeology studies. In this work, we provide a first hydrogeoche- mical characterization of the groundwater in the area. To do so, we have: i) compiled existing hydrogeological information, ii) exhaustively developed an inventory of water points, iii) sampled and analysed groundwaters and iv) interpreted the hydrochemical facies detected. The three aquifer systems defined by Garrido-Schneider (1995) have been improved. The most important one, the Santo Domingo-Salinas system, it is composed of Mesozoic and Cenozoic limestones formations. The che- mical analyses of groundwater allow us to differentiate four main types: a) calcium bicarbonate drained by limestones from the Cretaceous-Eocene aquifer, b) calcium-magnesium bicarbonate drained by limestones and dolomites from Muschelkalk facies (Triassic), c) calcium sulfate and d) sodium chloride, both related to siltstones and evaporites found within the Keuper facies (Triassic).
