Groundwater quality from water wells of the Koprivnica-Križevci County, northwestern Croatia
The aim of this study was to investigate during two-years monitoring campaign the physicochemical and microbiological quality of groundwater from water wells of the Koprivnica-Križevci County in Northwestern part of Croatia. Tested groundwaters are used as the sources of drinking water for local population i.e. over 115.000 people, and they are originated from few aquifers with different geological structure and terrain morphology, which has a significant impact on the groundwater quality. A groundwater samples were taken from five water wells (Ivanščak, Trstenik, Vratno, Đurđevac and Delovi) were analyzed on seven microbiological parameters (total coliforms, Escherichia coli, colony count at 22°C and 37°C, enterococci, Pseudomonas aeruginosa and Clostridium perfringers) and forty seven physical and chemical parameters. Since recent studies shown frequent appearance of heightened nitrate concentrations in natural waters in Koprivnica- Križevci County, due to relatively high degree of agriculture activity, among analyzed parameters, special focus of interest was nitrate concentration in sampled water wells. Comparing the concentrations of dominant anions and cations at sampled groundwaters, the water-bearing zones are determined. The results shown that groundwater samples taken from water well Delovi continuously were non-compliance due to regulation because of elevated values of turbidity and total iron concentration. All other groundwaters sampled during this twoyears study was in compliance with Croatian regulations and European Directive.
