Sažetak
Studies were undertaken of three types of water sources for drinking and watering. An uncovered 1O-m deep well situated in a rural area, a closed 50-m deep borehole of a small town waterwork, and a brook for livestock watering, which flows all along the grassland, all of them adjacent to the soil fertilized with slurry or animal manure, were included. Study results pointed to a deteriorated bacteriologic and physico-chemical quality of the well water throughout the year, being worse during the wet period ( NO3-N mean, 19.8 mg/L ), whereas the water from the waterworks borehole was found to be correct, with the exception of nitrogen compounds, especially nitrates ( NO3-N mean, 12.9 mg/L), which was also more pronounced during the wet period. The quality of brook water was hygienically correct, with elevated nitrate values ( NO3-N mean, 11.9 mg/L ) before, and heavily deteriorated after spreading pig slurry over the nearby grassland. After two months, the quality of brook water improved, but still did not reach the initial quality .
