In paper a groundwater quality on sewerage and non-sewerage areas in chosen community was presented. Ten control points were localised in nonseweraged villages and two in seweraged one. Analyses were carried on in summer 2007. The colour, turbidity, reaction, conductivity, nitrite nitrogen, nitrate nitrogen, ammonia nitrogen, manganese, iron and amount of bacteria coli were analysed in each sample. Obtained results were put through statistical analyses in which an essential differences of groundwater pollution index values to be tested between seweraged and non-seweraged areas. ...
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. ...
