| contents | Rapid isotopic changes in groundwater, upper Rio Guanajuato catchment, Mexico Stefanie Kralisch Alejandra Cortés Jaime Durazo Ciencias de la Tierra Mexico Guanajuato rapid aquifer evolution Recent isotopic change in oxygen18 and deuterium in groundwater Signifi cant changes in the isotopic composition of groundwater in the upper catchment of Rio Guanajuato, Mexico, weredetected in two independent sets of samples for 3 % of the 1600 highproduction wells in the area. Sampling was done in December1998 (53 samples), and in July August 2003 (41 samples). Average deuterium concentration did not change between 1998 and2003 but the average oxygen18 concentration suggested a generalized dilution from deep water from infi ltrated local precipitation.This regional change occurred within 56 months, indicating a highly dynamic hydrogeologic system. Fast replenishment of aquiferstorage, or non sustainable overpumping of old aquifer reserves, are possible explanations. 2007 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56846105 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.1 Vol.46 |
