The Artemisa–Quivicán Basin is located in the southern sector of the province of Havana, Cuba. This basin contains the most important aquifer of Havana province. It has a length of nearly 120 km and is 25 km in width. Recharge depends on the precipitation regime and rain iniltrates in a considerable proportion due to the intense development of karstic features. 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. The main objective of this study is the isotope and chemical characterization of the aquifer and the delimitation of the area inluenced by saline intrusion. Groundwater and river water are of the calcium bicarbonate type except those with evidence of mixture with saline water. Groundwater exhibits a variable proportion of mixture with seawater, indicating the presence of the saline intrusion
