The Artemisa-Quivicán Basin or South Basin (“Cuenca Sur”) is located in the southern sector of the Havana province, Cuba. This Basin contains the most important aquifer of Havana province. It has nearly a length of 120 km and 25 km of width. The recharge depends on precipitation regime and rain infiltrates in considerable proportion due to intense development of karst. This aquifer is used for water supply to population, industry and irrigation and is affected by overexploitation and risk of contamination by saline sea intrusion.  This investigation was supported by the International Collaboration Project CU/07/01 between Argentina (MINCYT) and Cuba (CITMA). The main objectives are the isotope and chemical characterization of the aquifer and the delimitation of the area influenced by saline intrusion. Groundwater and river water are calcium bicarbonate type except those with evidences of mixture with saline water. Their compositions vary depending on the mixing ratios.  Isotope results show the meteoric origin of waters. Groundwater exhibits variable proportion of mix with sea water indicating the presence of the saline intrusion.
