The exhaustive knowledge of the geological, hydrogeological, and geochemical setting can be very effective to define an alternative strategy to mitigate the arsenic problem in water. The magnitude and extension of the arsenic affected areas is not well known. In order to understand the source of the arsenic, the development of a database of thermal waters in the Andean region is in progress. We present in this work the assessment of more than 360 hot springs and wells located in the Andes between 14 and 52oS of latitude. This information comes from projects carried out by our team in the area and from references. The hot waters with higher concentrations of arsenic (50-30,000 μg/l) are mainly located in volcanic areas with hydrothermal activity of the Andes Cordillera between 14 and 28oS. | Descripción: | 1 página.-- Resumen presentado en el 23rd International Applied Geochemistry Symposium (IAGS), Oviedo, 14-19 Jun. 2007.-- Edited by Jorge Loredo Pérez. | Versión del editor: | http://www.appliedgeochemists.org/events/iags2007/Abstracts_and_Program.pdf | URI: | http://hdl.handle.net/10261/31923 | ISBN: | 978-84-690-6461-0 |
