Summary:

In the work presented and discussed the results of the study of groundwater in the area of the landfill site, which has been done in the years 2004 - 2008 in three piezometer points. For the analysis were taken into account the value of the reaction, electrolytic conductivity, TOC, Cr + 6, Pb, Cd, Hg, Zn and PAH. The results of the test of groundwater are normative values of Polish Standards, as well as the comparative analysis was taking into account the direction of their flow. The topic of the work was to assess the quality of these waters at the stage of the operation of the municipal landfill site. Tested waters in area of the landfill site was characterized by variability of their composition. In particular, an increase in the content of cadmium has confirmed influence of waste in underground waters on their outflow and on their qualities in result limited proficiency of drainage system of the landfill site. However, increased contents of product of incomplete combustionof organic product on inflow so as well outflow of this water it has exerted relationship with interaction of the effects of anthropogenic.
