Electric conductivity (EC), concentrations of major ions, total organic carbon, total nitrogen, optical density at 254 nm (D 254 ) and fluorescence intensities characterizing protein-like and humic-like fluorescence were determined in water samples of urban river Okhta. Principal component analysis for values of measured parameters found 5-6 principal components (PC), three of them were explained by loadings values. PC1 was responsible for the most part of variance and reflected wastewater pollution with dissolved salts and organic matter. PC 2 was supposed to reflect organic matter of natural origin from the unpolluted stream water. Combination of EC and fluorimetric parameters of water were suggested for pollution monitoring in river waters.
