Analýza kvality pitné vody v jižních Čechách
VRÁNEK, Ivo
The goal of diploma thesis was a comparison of potable water indicators in representative areas of the south Bohemia. Monitored period had been from January 2012 till December 2014. Monitored parameters were microbiological indicators (Escherichia coli, coliform microbes, number of colonies at 22°C, number of colonies at 36°C, organoleptic indicators (color, turbidity, smell, taste). Physical and chemical indicators (ammonium ions, nitrates, nitrites, chemical consumption of oxygen, chlorides, conductivity, manganese, pH, sulphates, calcium and magnesium, iron). From the total complex of 1165 data, there were 23 values over the limit (1,97%) of evaluation of all monitored quality indicators (microbiological, organoleptic, physical and chemical). In evaluation of microbiological indicators, there were 6 values (1,97%) over the limit, from total 304 data. In organoleptic indicators, there was 1 value (0,44%) over the limit, from total 227 data. In evaluation of physical and chemical indicators, there were 16 values (2,52%) over the limit, from total 634 data. In total, there are 23 values which don´t meet determined limits from The Regulation No. 252/2004 and EU directives. There are these values of limits - number of colonies at 22°C, number of colonies at 36°C, turbidity, manganese, calcium and iron.
