Abstract

QUINO, Israel; QUINTANILLA, Jorge; GARCIA, Maria E.  and  CACERES, Luis. DETERMINACION DE LA CALIDAD FISICOQUIMICA DE LAS AGUAS SUBTERRANEAS EN LA REGION NORTE Y ESTE DEL LAGO POOPO. Rev. Bol. Quim [online]. 2006, vol.23, n.1, pp.48-52. ISSN 0250-5460.

The hydrochemistry study is developed, with the intention of knowing the quality groundwater in function the physicalchemistry characteristics and heavy metals: by natural effect and the mining activity in the north and east of the region of the Poopó lake. We studied the evolution of the salinity in function to the permanence time of groundwater. Exist problems by salinity: HCO3-, SO4=, Cl- and Na+. The studied heavy metals: As, Fe y Zn don’t present elevated concentrations, probably to that they are retained by the ground, can’t be affirmed a geographic distribution for heavy metals and for the salinity. We made a classification on the basis of the studied parameters, using the Bolivian legislation and other international, comparing groundwater between for determining which is the that presents better characteristics for use.

Keywords : Agua subterránea; salinidad; metales traza; contaminación.
