Sažetak
The water supply network of the Čabar area (Čabar is a little place in Gorski kotar, mountain part of Croatia) has been carrying bacteriological contamination for many years. The aim of the paper is to present a five-year microbiological profile of drinking water used for supplying the field area. Methods: The collected data for Čabar, Gerovo, Prezid and Tršće water sourses were obtained from the Department of Public Health, Primorsko-Goranska County. Data were statistically processed and interpreted for the period from January the 1st 2012. to December the 31 st2016. The number of tested samples is 435 and the analyzed parameters are temperature, color, turbidity, pH, conductivity, KMnO4 consumption, ammonia, coliform bacteria, Escherichia coli, Enterococci, colonies at 37 °C and colonies at 27 °C, Pseudomonas aeruginosa and free chlorine. Results: The highest number of bacteriologically defective samples in the five-year period was in Čabar’s water supply with 33% of defective samples compared to the total number of measurements and the Gerovo water supply with 29%. The contaminated samples contain Escherichia coli (fecal contamination indicator) and are most present in the Čabar water supply (28%), followed by Gerovo (24%), Tršće (10%) and Prezid (9%). Conclusion: Due to fecal contamination, these water supply systems are unsafe for human health because they are the potential causes of the hydric epidemic and need to continue to invest in the protection of sources and sanitary-technical maintenance of the water supply system with regular chlorination.
