The aim of this work was to determine the quality of water from wells in different locations in the village of Lovča, which does not have a public water supply system and its citizens get their water supplies individually from their own sources. To compare altered hydrologic conditions in various times of the year, total of 10 samples of well water were taken in summer and winter season (June and November 2016). In each sample 13 physico-chemical indicators (nitrates, nitrites, fluorides, absorbance, ammonium ions, total dissolved solids, chemical oxygen consumption from permanganate, reaction of water, sulfates, conductivity, calcium and magnesium), and 6 microbiological indicators (Enterococci, Coliform Bacteria, cultivable microorganisms at 22 °C, microorganisms cultivable at 37 °C, Micromycetes, iron and manganese bacteria) were determined. The measurement results were compared to limits given by SR Government Regulation No 364/2006 Coll. It is obvious from the outcome that in the majority of the samples organic contamination was detected in the form of the increase in chemical oxygen demand. Increased amount of nitrates apparently indicates agricultural activities nearby the village. From microbiological point of view the situation is also unsettling, as in several samples limit values were exceeded. This work further discusses possible causes of individual water supply pollution in wider context of environmental influence of nearby industrial and agricultural sources. In conclusion, remedial measures, methods of decontamination, possible prevention and maintenance of drinking water supply are recommended.
