AbstractThe comparison of the arsenic contents in the watersheds of the Pergamino-Arrecifes Rivers and Salado River in the Province of Buenos Aires, Argentina shows higher values in the latter. The opposite is observed in the volcanic glass content of the sediments, 30% and 20%, respectively. The traditional interpretation of the relationship arsenic content-volcanics in sediment is questioned. Arsenic origin could be related to the volcanism and associated hydrothermal activity of the Andes Cordillera between 14 and 28°S. Secondary dispersion by means of surface waters would be the main process implied in arsenic transport to the aquifers. The change from being airborne to being drainage-borne has important consequences in the understanding of the regional distribution of arsenic. This new perspective can support new ways for water quality management in relation to the exploration and use of alternative low arsenic water sources.
