Abstract

Chemical characteristics of stream water at Asprolakkas hydrological basin were determined in February 2009 in order to examine the main factors controlling the hydrogeochemistry of the drainage system. A total of 20 surface water samples were collected and analyzed for the major ions K, Na, Ca, Mg, HCO3, SO4 and the trace elements Fe, Pb, Zn, Mn, Cu, Ni, As, Sb, Mo and Ba. The application of R-mode factor analysis revealed that the polymetallic carbonate replacement type sulfide deposits, together with the porphyritic intrusions and the associated porphyry copper style mineralization, occurring in the studied area, impose fundamental control on the water chemistry. A third influencing factor includes the parameters As and HCO3 and is attributed to the competitive behavior of As and bicarbonate ions, for filling in available absorption space on Fe(III) oxides. SEM-EDS methods, performed on retained filters from the filtration of representative water samples, showed that Pb is mainly transported by fine particulate matter. The chemical elements Mn, Zn, Mo and Sb are predominantly present as dissolved free ions, and correlate strongly with the electrical conductivity of the water samples.
