Ground water in the Jaffna Peninsula, an area of 1,065 square kilometers (411 square miles) located at the northern tip of Sri Lanka (Ceylon), occurs within solution openings of the Jaffna Limestone of Miocene age. The freshwater forms a complex of lenses up to 25 meters (80 feet) thick overlying saline water derived from the sea that nearly surrounds the Peninsula. Recharge to the aquifer is from monsoonal rains during OctoberDecember. Known discharge from the aquifer is primarily from withdrawal of water from about 100,000 wells and by discharge to the sea through springs and seeps along the north coast. Discharge through springs and seeps, which takes place primarily during and shortly after the monsoon, appears to be small compared to withdrawal from wells. Pumping from more than 19,000 shallow dug wells in an intensively studied 142 square kilometer (55 square miles) area of the Peninsula was 55.5 million cubic meters (45,000 acre-feet) in 1976 whereas discharge to visible seeps and springs within that area is estimated at 9.3 million cubic meters (7,500 acre-feet) per year. 1
