Abstract

Cilj ovog istraţivanja bio je analizirati kvalitetu vode za ljudsku potrošnju, s obzirom na mikrobiološke pokazatelje, na području grada Zadra i dijela Zadarske ţupanije, koju zahvaća, kondicionira i distribuira Vodovod d.o.o. Zadar. Uzorci su uzeti u svim dijelovima vodoopskrbnog sustava, od neobraĎene vode na vodozahvatima do krajnjih korisnika. Analizirani su metodom membranske filtracije i kultivacijom na hranjivim podlogama radi utvrĎivanja prisustva aerobnih mezofilnih bakterija, ukupnih i fekalnih koliforma, enterokoka, bakterija Escherichia coli, Clostridium perfringens i Pseudomonas aeruginosa. Na osnovu izmjerenih vrijednosti i definiranih maksimalno dopuštenih koncentracija pojedinih pokazatelja, odreĎena je zdravstvena ispravnost vode. Mikrobiološka analiza je pokazala da su svi uzorci neobraĎenih voda bili zdravstveno neispravni, dok je postotak neispravnih uzoraka obraĎenih voda vrlo nizak.

Abstract (english)

The purpose of this research was to analyse the quality of water for human consumption, regarding microbiological indicators, covering the area of the town of Zadar and the part of the Zadar county, which is captured, treated and distributed by Vodovod Ltd. Zadar. The samples have been taken in every part of water supply system, from untreated water on water springs to the end users. They have been analysed using the membrane filtration method and cultivation on various nutrient media in order to define the presence of aerobic mesophilic bacteria, total and faecal coliforms, enterococcs, bacteria Escherichia coli, Clostridium perfringens and Pseudomonas aeruginosa. Based on these measured values as defined by a maximum allowed concentrations of certain indicators, the water consumption safety has been determined. The microbiological analysis has shown that none of the samples of untreated water were sanitary acceptable, while the percentage of unsuitable samples of treated waters was very low.
