Abstract

U ovom diplomskom radu određene su hidrogeokemijske značajke podzemne vode u Zagrebu, Sisku i Slavonskom Brodu. Uzorkovanje je izvršeno u razdoblju od siječnja do prosinca 2023. godine, u mjesečnom intervalu. Podzemna voda uzorkovana je na četiri lokacije: piezometar PZO-21 (Zagreb), piezometar S-N i kopani zdenac BM-03 (Sisak) i piezometar P-9 (Slavonski Brod). Koncentracije osnovnih iona određene su pomoću ionske kro-matografije i titracije. Za određivanje hidrogeokemijskih facijesa i dominantnih hidrogeokemijskih procesa kori-šteni su Piper-ov dijagram, Durov dijagram i Gibbs-ov dijagram. Interpretacijom rezultata uzorci podzemne vode PZO-21, P-9 i BM-03 pripadaju CaMgHCO3 (kalcijsko-magnezijsko-hidrogenkarbonatnom), dok uzorak S-N pri-pada NaHCO3 (natrijsko-hidrogenkarbonatnom) tipu voda. Dominantan hidrogeokemijski proces u podzemnoj vodi na lokacijama PZO-21 i BM-03 je otapanje karbonata, u podzemnoj vodi, na lokaciji S-N to je otapanje silikata, dok su u podzemnoj vodi, na lokaciji P-9 jednako važna oba procesa. Na uzorcima S-N i P-9 provedene su dodatne analize poput atomske apsorpcijske spektrometrije, laserske difrakcije, gravimetrije te rendgenske difrakcijske analize. Dobiveni rezultati upućuju na povišene koncentracije željeza i ujednačeniju raspodjelu veličine čestica u uzorku P-9, u odnosu na uzorak S-N.

Abstract (english)

This thesis defines hydrogeochemical characteristics of groundwater in Zagreb, Sisak and Slavonski Brod. Water sampling was performed from January to December 2023, in a monthly intervals. Gro-undwater was sampled in four locations: observation well PZO-21 (Zagreb), observation wells S-N and BM-03 (Sisak) and observation well P-9 (Slavonski Brod). Concentrations of basic ions were determi-ned by ion chromatography and titration. Piper diagram, Durov diagram and Gibbs diagram were used to determine hydrogeochemical facies and dominant hydrogeochemical processes. Results interpretation indicates that groundwater samples of PZO-21, P-9 and BM-03 belong to the CaMgHCO3 (calcium-magnesium-hydrogen carbonate), while the S-N sample belongs to the NaHCO3 (sodium-hydrogen car-bonate) water type. The dominant hydrogeochemical process in samples PZO-21 and BM-03 is carbo-nate dissolution, in sample S-N silicate weathering, while in sample P-9 both processes are equally relevant. Additional analyses such as atomic absorption spectrometry, laser diffraction, gravimetry and X-ray diffraction analyses were performed on S-N and P-9 samples. The results indicate higher iron concentrations and a more uniform particle size distribution in sample P-9 compared to the observation well P-9.
