The aim of this paper is to compare the chemistry of surface waters taken from two areas: Poland (Wielkopolska) and Lithuania. These two areas have different environments and different agricultural utilization. The high concentration of both nutritive compounds and dissolved humic substances were found in the Wielkopolska Region, where a great proportion of cultivated fields and intensive agrotechnics are observed. Surface waters located in Lithuania, with a high percentage of wasteland such as bogs, pastures and meadows, showed much lower concentrations of the analysed components. The analysis of content of heavy metals in surface waters showed much greater concentrations of manganese, lead and zinc in Lithuanian water, which can be related to considerable atmospheric pollution of this area.
