Since not much information about the groundwater of Miren – Vrtojba intergranular aquifer is known, groundwater sampling of this aquifer has been performed since 2008. The research had the aim to determine the chemical composition of groundwater, the aquifer’s recharge area and its influence on the geochemistry of groundwater, the share of the sources feeding the aquifer, and the potential sources of pollution which influence the groundwater chemical status. The recharge area of the intergranular aquifer was assesed to be around 12.8 km2, with groundwater flow direction NE – SW. Chemical analysis of shalowed groundwater showed that most sampled waters belongs to the Ca-HCO3 water type. Ca2+ prevails over Mg2+ in the water, where Ca/Mg molar ratio and stable oxygen isotope data suggested that the aquifer might be partly fed by the Soča River in the north, and by the Vipava River in the southern part of the field. Occurance of nitrate has it's origin in increased use of fertilizer on the fileds and in the decripit sewer infrastructure. The presence of bacteria in groundwater suggests that water is by no means suitable for drinking.

COBISS.SI-ID: 1975637In article application of passive sampling with granular activated carbon for qualitative monitoring as a part of “grab” quantitative monitoring is presented. Passive samplers were installed in selected observing boreholes for few months. For the interpretation of chromatograms the AMDIS deconvolution was used. Deconvolution was covered by GC-MS library with retention times for 921 organic contaminants from Agilent USA and also the NIST 2008 library of mass spectra. Evaluation of different pollutant groups with respect to their origin was performed.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 2007125The article deals with the issue of groundwater, which represents a source of 97% of drinking water in Slovenia. It addresses the debate whether the resources of groundwater bodies (or aquifers) are subjected to the diminishing trend. The current results of monitoring show that in a long term Slovenia might be faced with a serious water resource shortage.
