Abstract:V diplomskem delu je prikazana analiza različnih vrst pitne vode v Sloveniji, pri čemer smo primerjali vzorce iz javnih vodovodov ter dveh domačih vodnih virov. Do sedaj za izbrana zajetja še niso bile izvedene celovite raziskave, ki bi enotno ocenjevale kakovost vode z indeksom kakovosti vode. Cilj diplomskega dela je bil določiti kakovost pitne vode z uporabo fizikalno-kemijskih analiz, mikrobioloških preiskav ter določitvijo vsebnosti per- in polifluoroalkilnih snovi. Fizikalno-kemijske parametre smo določali v vseh vzorcih, med njimi pH, motnost, električno prevodnost, trdoto, celotne raztopljene snovi ter koncentracije kalcija, magnezija in železa. V sodelovanju z Nacionalnim laboratorijem za zdravje, okolje in hrano smo izvedli mikrobiološke analize za potrditev zdravstvene ustreznosti pitne vode. V izbranih vzorcih iz Ljubljane smo analizirali tudi per- in polifluoroalkilne snovi. Končni cilj je predstavljala izračunana vrednost indeksa kakovosti vode po Brownu. Rezultati kažejo, da so fizikalno-kemijski parametri v večini primerov ustrezali zahtevam Uredbe o pitni vodi, izjema je bil vzorec domačega vira po obilnih padavinah, kjer je bila motnost presežena. Mikrobiološke analize so pokazale, da sta bila oba vzorca domačih pitnih vod, Slovenj Gradec in Otiški Vrh, mikrobiološko oporečna, medtem ko so vzorci javnih vodovodov ustrezali zahtevam. Izračunani indeks kakovosti pitne vode je potrdil, da je kakovost vode iz javnih vodovodov izjemno visoka, medtem ko domači viri zahtevajo pogostejši nadzor.

Title:Determination of the quality index of different types of drinking water
Abstract:This thesis presents an analysis of different types of drinking water in Slovenia, comparing samples from public water supply systems and two domestic water sources. So far, no comprehensive studies have been carried out for the selected catchment areas that would allow a standardised assessment of water quality based on the water quality index. The aim of the work was to determine the quality of the drinking water using physico-chemical and microbiological analyses as well as the determination of per- and polyfluoroalkyl substances. Physico-chemical parameters were determined in all samples, including pH value, turbidity, electrical conductivity, hardness, total dissolved solids, content and the concentrations of calcium, magnesium, and iron. Microbiological analyses were carried out in collaboration with the National Laboratory of Health, Environment and Food, to confirm the hygienic suitability of the drinking water. Per- and polyfluoroalkyl substances were also analysed in selected samples from Ljubljana. The final goal was to calculate the water quality index. The results show that the physico-chemical parameters met the requirements of the Drinking Water Regulation in most cases, with the exception of the household source after heavy rainfall, where the turbidity was exceeded. The microbiological analyses showed that both household water samples, Slovenj Gradec and Otiški Vrh, were microbiologically non-compliant, while the samples from the public water supply met the standards. The calculated Water Quality Index confirmed that the water from the public water supply is of excellent quality, while the domestic sources need to be monitored more frequently.
