QUALITY AND EVALUATION OF WATER SAMPLES FROM INDIVIDUAL WATER SOURCES IN BRATISLAVA AND THEIR COMPARISON ON THE BASIS OF SELECTED INDICATORS FOR 2017

Summary/Abstract: Introduction: Clearly clean water with a good well of well does not always have to be safe and safe to drink. Objective: To Determine water quality from selected individual drinking water sources (wells). This paper describes an extraordinary monitoring of drinking water quality due to illegal non-specific landfill in Vrakun (Bratislava, Slovakia). Materials and Methods: Water sampling was performed in four city districts of Bratislava (Vrakuňa, Rača, Dúbravka and Petržalka) in spring and autumn months (March and September 2017) Samples were taken from selected sources of drinking water from individual wells of individuals. Results of analysis were compared to set standards according to the Decree of the Ministry of Health of the Slovak Republic No. 247/2017 Coll. The analysis was focused on three chemical indicators (Lead, Total Organic Carbon - TOC, Copper) and three microbiological indicators (Escherichia coli, Coliform bacteria, Cultivable microorganisms) of water quality. Results: A summary analysis showed that chemical indicators were always significantly higher in March 2017 in comparison to September 2017. Conclusion: The results of analyzes of samples from individual drinking water supplies from selected Bratislava and surrounding city districts as a result of suddenly discovered unauthorized landfill did not confirm that the limit values were exceeded to an extent posing a serious risk to health.
