In the present study, surface waters in hydrographic area, situated in mining region, in the vicinity of abandon copper mine, are characterized and their quality assessed from the view point of the requirements of European Water Frame Directive and Drinking Water Directive. Three sampling campaigns starting at 2012 from 16 sampling sites, in different seasons were performed in order to evaluate both natural, seasonal variations connected with water regimes and anthropogenic pressures. Chemical elements (Al, As, Ba, Cd, Cr, Co, Cu, Fe, Hg, Mn, Ni, Pb, Se, U, V, Zn and lanthanides) and physicochemical parameters (pH, conductivity, hardness, chemical oxygen demand (CODKMnO4); biological oxygen demand (BOD5); dissolved oxygen; dissolved solids; suspended matter; dry residue; chlorides; sulphates; nitrates; phosphates) were measured for characterization and evaluation of different water sources in the region. Conclusions for the further use of waters from this region as tap waters were presented and validated through the determination of much more chemical elements than these required from national legislation.enArticle
