Hidrogeoquímica e isotopía ambiental del sector noreste de la Serra de Tramuntana, isla de Mallorca (España)

Groundwater flow in the Serra de Tramuntana, a UNESCO World Heritage Site in Mallorca, Spain, aligns with existing models but includes key modifications. The study reveals that groundwater is predominantly calcium-bicarbonate, except near S'Almadrava where marine intrusion elevates chloride levels. High sulfate concentrations, notably at Ses Ufanes and Sa Costera, link to gypsum layers in the Keuper formation. Using environmental isotopic analysis and the MULTIS code for radioactive isotope interpretation, researchers refined the conceptual model of groundwater flow, confirming a recharge rate of 0.3 to 0.5 times annual precipitation, higher at elevated areas. This work supports sustainable management of Mallorca's strategic subterranean water resources.
