Thus, the paper aims to meas ure Nickel (Ni) and Zinc (Zn) concentrations in many depths of the dam’s bottom, sampling cores of se diments silted in it. The samplings were carried out in June, 2014, and it was sampled four sediment cores in pre-defined points of the dam. The methodology for extraction of sediment cores was ‘Pisto n Core’. Sediment particles smaller than 63 μ m were separated and used for chemical an alysis. EPA 3050 acid digestion methodolog y is used by the U.S. Environment Protection Agency and it was also used in this study. Analyses were carried out in duplicate and two USGS reference materials were used for quality control: SGR-1b and SCO-1. Zn and Ni concentrations were over than local background values and increasing co ncentrations of the deepest sendiments to the most recent layers as a result of urbanization activities. Geoaccumulation index was able to characterize decreasing of metal concentrations in depth. 2017 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303252892012 https://www.redalyc.org/journal/3032/303252892012/ https://www.redalyc.org/journal/3032/303252892012/html/ https://www.redalyc.org/journal/3032/303252892012/303252892012.epub https://www.redalyc.org/journal/3032/303252892012/movil en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
