As an advance towards the design of a strategy for bioremediation of the mine “El Dollar”, the study of the quality of water flushing out of the mine and their impact in the Lagoon San Francisco (Huancavelica, Perú) was carried out. Analytic results obtained from field sampling in 2006 indicated that the water of the lagoon has not undergone significant impact due to heavy metal concentration. The concentration of Mg, Na and Ca in water suffered very little transformation during their journey from the mine entrance to the lagoon. The biggest transformation occurred with Zn, Cu, Fe, and Mn which are retained inside the terrestrial ecosystem. On basis of the observed results, Pb and Mn should be considered as elements of importance inside the plan of bioremediation of this ecosystem.
