ANALYSIS OF DRINKING WATER FROM WELLS IN BRODSKO-POSAVSKA COUNTY

U ovom radu provedena je analiza vode za piće iz zdenaca u Brodskoj-posavskoj županiji koja uključuje fizikalno-kemijsku i mikrobiološku analizu. Uzorci vode su uzorkovani sa 4 različite lokacije. Analiza je obavljena u Zavodu za javno zdravstvo Požeško-slavonske županije. Određivali su se slijedeći mikrobiološki parametri: ukupni koliformi, ukupan broj kolonija na 36 °C i 22 °C, Escherichia coli, enterokoki te fizikalnokemijski: mutnoća, elektrovodljivost, pH, kloridi, utrošak KMnO4, amonijak, nitriti, nitrati i boja. Mikrobiološkom analizom je pokazano da niti jedan uzorak ne zadovoljava mikrobiološke kriterije koji su određeni Pravilnikom o parametrima sukladnosti, metodama analize, monitoringu i planovima sigurnosti vode za ljudsku potrošnju te načinu vođenja registra pravnih osoba koje obavljaju djelatnost javne vodoopskrbe (NN 125/2017). Fizikalno-kemijskom analizom je pokazano da svi uzorci, osim mutnoće u uzorku 1, udovoljavaju kriterijima.In this paper, the analysis of drinking water from wells in Brod-Posavina County was performed, which includes physico-chemical and microbiological analysis. Water samples were sampled from 4 different locations. The analysis was performed at the Public Health Institute of Požega-Slavonia County. The following microbiological parameters were determined: total coliforms, total number of colonies at 36 °C and 22 °C, Escherichia coli, enterococci and physicochemical: turbidity, electrical conductivity, pH, chlorides, consumption of KMnO4, ammonia, nitrites, nitrates and dyes. Microbiological analysis has shown that none of the samples meets the microbiological criteria set out in the Ordinance on compliance parameters, methods of analysis, monitoring and water safety plans for human consumption and the manner of keeping the register of legal entities performing the activity of public water supply (OG 125/2017). Physico-chemical analysis showed that all samples, except turbidity in sample 1, meet the criteria
