Summary:

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.
