Hydrogeochemical techniques provide a complementary tool to hydrogeology as they provide certainty as to the questions related to complex systems, as is the case of coastal aquifers, in which salinity, usually associated to saline intrusion processes, may result from the fusion with other hydroclimatologic and hydrodynamic aspects. With the application of hydrogeochemistry and ionic relations, it has been evidenced that salinization processes in the coastal aquifer of Urabá Banana Axis could be linked to water-rock interaction, to mixtures with waters which salinized as a result of old transgression-regression processes in the zone under study. This article summarizes the results of the research project, the application of hydrogeochemistry, and ionic relations as a valid methodology to determine the different salinization processes of coastal areas.

Keywords : hydrogeochemistry; salinization; aquifer; intrusion.
