Abstract: The content of nitrates (NO3-) were assessed in the period 2012 - 2013 in samples taken from individual groundwater sources (Svorad´s spring, Puškin´s spring, spring on Pivoňková street, spring on Mriánska dolina, spring Šindolka and spring Buganka) in the administrative area of Nitra and Zobor , also used for human consumption. The content of NO3- were assessed by Photocolorimetric method. We also evaluate the results achieved in relation to the current legislation of the area.
From the result of the performed analyzes during the whole period shows that the average concentration of NO3- represented in samples of water from the source Svorad´s spring 12,1 mg.dm-3, Puškin´s spring 14,6 mg.dm-3, from spring St. Martina 117,0 mg.dm-3, from spring on Pivoňkova street 6,4 mg.dm-3, from spring Šindolka 39,5 mg.dm-3 and spring Buganka 101,7 mg.dm-3.
The nitrate concentration exceeded the limit value in 16 % of cases in 2012 and it was 17 % of cases in 2013. Based on the measured values, therefore we do not recommend to use the water for human consumption from springs Buganka and St. Martina at the endpoint.
