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 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. ...
Leachates in the landfill site both result from direct flow of water from atmospheric precipitations and arise during the process of biochemical changes, most frequently organic compounds. The aim of the research was presentation of several selected heavy metals content in the leachate from landfill site posing a hazard to the environment. The landfill site is situated in Wola Suchożebrska, in the eastern part of the Mazowieckie voivodeship in the Podlaski county. It receives waste from the city of Siedlce and several neighbouring communes. Leachates were collected in compliance with the PN-ISO 5667-10:1997 standard taking in to consideration the vertical stratification of the leachate quality. The research covered concentrations of Pb, Cd, Cu, Zn, Cr and Hg. No elevated concentrations of any of the analyzed indices was assessed over the 2007-2012 period in industrial waste supplied to the sewer system. Obtained results confirmed that during the recent years of the landfill exploitation it has been receiving only wastes whose storage does not pose a potential source of environmental pollution with heavy metals, on condition that proper accumulation and treatment of leachates is maintained. ...
