Defining hydrochemical facies of water from springs on northern Bilgora slopes near Koprivnica : master’s thesis

U okviru diplomskog rada napravljena su kabinetska, terenska i laboratorijska istraživanja vode s izvora na sjevernim obroncima Bilogore u blizini grada Koprivnice. Odrađeno je hidrogeološko kartiranje područja u svrhu identificiranja izvora vode. Ukupno je pronađeno 13 stalnih i 24 povremena izvora. Uzorkovano je devet stalnih izvora i jedna primitivna kaptaža. Na terenu je mjerena temperatura, pH i oksidacijsko-redukcijski potencijal vode. Nakon uzorkovanja, provedeno je laboratorijsko ispitivanje vode pomoću postupaka titracije i ionske kromatografije, kako bi se odredile koncentracije osnovnih iona u vodi. Određene koncentracije korištene su za određivanje hidrokemijskog tipa vode. Voda s promatranih izvora pripada Ca-Mg-HCO3 tipu vode.Graduation Thesis deals with cabinet, field and laboratory research of water from springs on northern slopes of Bilogora mountain near the town of Koprivnica. Research area was hydrogeologically mapped with a goal of identifying water springs. Through mapping, 13 permanent and 24 temporary springs were found. Samples were taken from nine permanent springs and one well. Measuring of temperature, pH and oxidation reduction potential was conducted during field work. Water samples were examinated in laboratory using titration and ion chromatography method to determine ion concentrations in water. Concentrations were used to define hydrochemical facies of water. Sampled water belongs to Ca-Mg-HCO3 type of water
