Rapid isotopic changes in groundwater, upper Rio Guanajuato catchment, Mexico

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 high–production wells in the area. Sampling was done in December1998 (53 samples), and in July – August 2003 (41 sampl...
