Resumen:
Fluoride pollution is a widespread distributed problem in Argentina, as in many areas of the World. High concentrations up to 10 mg/l have been reported in groundwater in the central area. Former investigations demonstrated that the dissolution of volcanic glass disseminated in the loess-like sediments is the main source of fluoride in the Argentine pampas. Nevertheless fluoride distribution is erratic and the factors controlling it are not well known. A large amount of hydrochemical information collected in the Quequen Grande River catchment is used in order to contribute to the understanding of fluoride distribution and mobility in groundwater in the Argentine pampas. The Quequen Grande river catchment is 10,000 km2. It extends between two low hills ranges of Precambrian metamorphic rocks and sedimentary Paleozoic rocks, and it is filled by a thick sequence of Cenozoic sediments, mainly silts and silty-clayed, with sand layers intercalated.  These sediments form a multilayer phreatic aquifer, which is recharged from precipitation infiltration, discharging trough streams of directly to the sea. Fluoride concentration in surface water (n = 353) ranges between 0 and 6.5 mg/l, with an average value of 2.14 mg/l. Groundwater concentration (n=135) is from 0 up to 5.7 mg/l, with an average of 1.84 mg/l. Fluoride pollution is a widespread distributed problem in Argentina, as in many areas of the World.
