3 very heavy contamination, 3>Cd>2 heavy contamination, 2>Cd> 1 moderate contamination, 1>Cd low contamination. The results show strong groundwater contamination. In 2013, in 67.5% of the examined wells, the water quality was very heavily or heavily contaminated. Only 15% of the water samples had a low degree of contamination. Three years after the sewage network was set up, significant changes were observed. In 2017 the proportion of highly or heavily contaminated wells dropped to 50%, thus the number of moderately contaminated wells more than doubled. The number of low-polluted wells also grew, but their proportion did not reach 20% in 2017. On the basis of the results, it can be concluded that the purification process has started, but it may takes several years. Further environmental measures are needed in order to eliminate these pollutants.]]>
