ABSTRACT The Artemisa-Quivicán basin is located in the southern sector of the Havana province, Cuba It is known as South Basin (“Cuenca Sur”). The South Basin is the most important aquifer of Havana province,THe recharge depends on precipitation regime and rain infiltrate 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, depletion and risk of contamination by anthropogenic action and saline sea intrusion. From the economic point of view this area is one of the most important agriculture and it has one of the main aqueducts that .provide water to Havana city (South Basin aqueduct). The main objectives of this work are the isotope and chemical characterization of the aquifer and to delimit the sector influenced by saline intrusion. This paper presents preliminary results obtained during the first research phase.
