The work evaluates the effect of anthropogenic pollutants on the quality of water in Lake Bialskie (51º32’07” N 23º00’55” E) and its catchment basin. Samples of water were taken from the lake (4 sampling points) and from wells dug within the catchment basin. The quality of water was analysed in May, June, August and November 2015. In the wells only in single cases was the level of chemical pollution found to exceed drinking water standards. However, in all samples the standard content of manganese was exceeded. In waters from the lake the concentrations of total phosphorus, which can contribute to eutrophication were recorded above the standard level. Both in waters from the lake and from the well a large count of meso- and psychrophiles and Coli and faecal coliforms as well as faecal Enterococci was found, which points to a high degree of contamination of the analysed waters with anthropogenic faeces. The phenomenon was observed to intensify in summer months, which can be associated with increased tourist traffic around the lake in this period.

Changes in the magnetic susceptibility of topsoil, especially in urban areas, are greatly affected by the deposition of anthropogenic metallic dust arising from industrial activities, the burning of fossil fuels, car wear, and tyre abrasion. In this study, magnetic susceptibility measurements were carried out in vertical soil profiles of 30.0 cm depth from the surface at 10.0 cm intervals in about 431 locations within the Abuja metropolis with a view to investigate the penetration ability of magnetic pollutants in the ground. From the obtained data, 3-D surface contour maps were plotted for different depths. The results show a magnetic susceptibility decrease from the surface down the ground to the depth of 30.0cm; most of the recorded susceptibilities were of an anthropogenic origin rather than pedogenic activities. This indicates that the anthropogenic dust depositions are mostly a surface phenomenon and may therefore not pose a risk to groundwater aquifers and near surface wells.
