Abstract

U razdoblju od dvije godine (2011. i 2012.) praćena je mikrobiološka ispravnost vode 20 izvorišta u Krapinsko-zagorskoj županiji. Pokazatelji su odabrani prema Pravilniku o zdravstvenoj ispravnosti vode za piće (Narodne novine broj 47/08). Sva ispitivanja provedena su prema standardnim metodama, važećim ISO i HR normama. Od 91 uzorka vode za piće čak je 65 uzoraka neispravno zbog prisutnih koliformnih bakterija, 41 uzorak je pozitivan na bakteriju Escherichia coli, 39 na enterokoke, povećani broj aerobnih mezofilnih bakterija pri 370C dokazan u 37, a pri 220C u 29 uzoraka vode, dok je bakterija Clostridium perfringens dokazana u samo jednom uzorku vode. Dobiveni rezultati pokazatelji su mikrobiološke kakvoće vode na izvorištima koja se koriste za opskrbu dijela stanovništva navedene županije.

Abstract (english)

In a period of two years (2011th and 2012th ) microbiological safety of 20 water sources in Krapina - Zagorje County was monitored. Indicators are selected according to the Regulation on the health suitability of drinking water (Official Gazette No. 47/08 ). All tests were carried out according to standard methods, the relevant ISO and HR norms. Of the 91 samples of drinking water even 65 samples is incorrect due to present coliform bacteria, 41 tested sample is positive for Escherichia coli, 39 sample is positive for enterococci, increased number of aerobic mesophilic bacteria at 370C is detected in 37 samples and at 220C in 29 samples of drinking water, while Clostridium perfringens is proved in only one sample of water. The results are indicators of microbiological quality of water at the water sources which are used for supplying one part of the population of above mentioned County.
