In this study the geochemical background of waters of Kola Peninsula in the context of decreasing the athropogenic pollution in that region was indicated. The study was conducted on 14 water samples from different phases of hydrological cycle- precipitation water, snow-melting water, ground water, river water, lake water, sea water; also 12 samples of rocks and soils were used. pH of waters, conductivity, isotopic ratio of δ18O i δD, concentration of ions (anions and cations) along with metal ions were analysed. For conductivity measure InoLab 1 (WTW) was used, cations and anions were indicated by ions chromatograph (Metrohm MIC 3), metal ions were indicated by spectrometer ICP-MS (Thermo Xseries2). Laser analyzer PICARRO L2130 was used for defining the isotopic ratio of δ18O i δD. Soils and rocks samples were analysed using scanning electrone microscope (Hitachi SU6600) with EDS add-on and spectroscope XRF Epsilon 3 (Pananalytical).

The study showed significant impact of bedrock and soils on ion composition of waters in different locations in Kola Peninsula in example on several geogenical metal ions of P, F, Cl, Fe, Mn, Cu, Ni, S. Chemical composition of water backround is strictly related to polymetalic rocks and metal ores of the Baltic Shield which build analysed area. The waters' richness in alkali minerals is due to alkaline bedrock occuring in numerous areas of Kola Peninsula. The content of metal ions like Zn, Pb, Cr, Cd in numerous water samples indicates severe anthropogenic influence on water composition which can be especially noticed in the composition of surface water affected by the nearby heavy industry plants thus pollution of surface water.

Analisys of water samples proves significant impact of geological structure on chemical composition of water and should be considered in reclamation of natural environment of Kola Peninsula from anthropogenic pollution.
