Summary:

In paper a groundwater quality near to municipality landfill was charac-terised. Groundwater analyses were carried on for 4 years in 3-4 months periods. Observation points around the municipal landfill site were localised in different distance to obtain different water flow times, i.e. since 30 to 800 m from landfill's border. Obtained results were put through statistical analyses in which the groundwater quality differentiation in different seasons as well as quality in sam-pling points from piezometers localised on groundwater inflow and outflow were assessed. Investigations carried out have enabled to evaluation of water quality changes in the vicinity of analysed landfill.
