Qualitative Analysis of Leachates from the Restored Landfill Site in Osowo, Karsin Commune

The article presents the qualitative analysis of leachates from the restored landfill site of non-hazardous and inert wastes in Osowo in the Commune of Karsin. The study was conducted on a semi-annual basis from 2012 to the first half of 2014 in compliance with the Polish law. The analysis concerned the variability of pH and proper electrolyte conductivity (PEC), the content of total organic carbon (TOC) and the sum of polycyclic aromatic hydrocarbons (PAHs) as well as selected heavy metals. The study of leachate waters indicated that the site is stabilised and it does not have a negative impact on the underground waters. There were no exceedances of permissible values for any of the analysed parameters; however, the content of most heavy metals as well as the sum of PAHs were below the limit of quantification of the analytical methods
