The Catalonian Potassic Basin is described as a tick regressive-sedimentary Tertiary basin that includes marine, evaporitic-transitional and continental facies, overlying by no-consolidated quaternary alluvial sediments. The intense underground mining activity used in the exploitation of salts with rich K contents in the CPC during the last century, has provoked some problems related to surface and groundwater contamination and the existence of subsidence areas. The objective of the hidrogeological studies in the CPC area are focused in the characterization of the Tertiary aquifer and the definition of their conceptual model of behaviour. The last challenge of the project is to determine the relationship between subsidence and hydrogeology in these salt bodies.
