NO3- contents were assessed by Photocolorimetric method. We also evaluated the results achieved in relation to the current legislation in this area. The results of the performed analyzes throughout the period shows that the average concentration of NO3- represented in the samples of water from Svorad’s spring was 12,6 mg.dm-3, spring Šindolka 38,0 mg.dm-3 and spring Buganka 103,1 mg .dm-3 The nitrate concentration did not exceed the limit value in samples from spring Šindolka and spring Svorad. Spring Buganka had this value exceeded by up to 100 % of cases. We do not recommend to use water for human consumption from spring Buganka based on the measured values.
