Monitoring of the groundwater environment within a landfill site

The paper presents the hydrogeological conditions and results of monitoring carried out within the "Otwock- wierk" municipal landfill site. The object is located within the Garwolin Plain - a denuded moraine plateau composed of deposits representing Middle-Polish Glaciations. Wastes are isolated from the surrounding soil-water environment by a 1-ply complex mineral-synthetic diaphragm. The periodical increase of chlorides, total organic carbon (TOC), polycyclic aromatic hydrocarbons (PAH) and nitrites indicate the presence of pollutants of anthropogenic origin.
