Presence in leachate waters very broad range of contaminants (both organic and mineral), causes, that the assessment of leachate composition is limited to indicators chosen by the researcher or imposed by regulations specifying the scope of monitoring. Comparing different objects can be facilitated by the Leachate Pollution Index (the LPI), which is calculated based on parameters, which have been acknowledged to have potentially the biggest impact on environment.The paper presents a method of determining the value of the LPI, also in the case where the results of some of the required physiochemical analyses are missing. On the basis of the information available in literature as well as the author's own research values obtained for selected national landfills have been compared. Using Maślice municipal landfill site in Wrocław as a case study, changes in the level of the LPI linked with age and changing ways of using the landfill site have been analyzed.The range of values of the indicator calculated for national landfill sites revealed extensive variation, however not diverging significantly from their Euro-pean counterparts. In all of the cases the leachate waters were characterizing high levels of chemical demand for oxygen (COD(Cr)), concentrations of ammonia ni-trogen and to some extent ...
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.
