In this article the results of analysis of selected water contaminants (nitrate nitrogen, chlorides, magnesium, sodium, potassium, calcium) in groundwater samples taken in spring and autumn of year 2006 from six piezometers located in the municipal waste dumping ground in Wojczyce area (completing the former monitoring), were presented.
Groundwater flowing to the municipal waste dumping ground in Wojczyce was characterized by the good quality. In groundwater flowing out behind the dumping ground an increase of analysed pollutants' concentration was observed, however only in some of the piezometers it caused essential deterioration of groundwater quality.
