Abstract

Z raziskavo vodnoekoloških razmer na območju doline Zaloka leta 2020 smo sledili predhodni terenski študiji iz leta 1978. Zajeto je bilo isto območje, ki je bilo prvotno preučeno kot potencialno območje zajema pitne vode, danes pa je vključeno v komunalno oskrbo s pitno vodo za več kot 30.000 ljudi. Na podlagi fizikalno-kemijskih kazalnikov posameznih vodnih virov in podnebno-geoloških značilnosti območja smo ohranjanje dobrega vodnoekološkega stanja preučenih vodnih virov povezali s padavinskimi in hidrogeografskimi razmerami širšega območja izvira Ljubija. Nizka vsebnost nitratov in majhna nihanja tudi ostalih parametrov kažejo na majhen vpliv človeka. The year 2020 water-ecological research followed the preliminary field study from 1978. We covered the same area of the Zaloka Valley, which was originally explored as a potential drinking water area, but today is included in municipal drinking water supply for more than 30,000 people. Based on physical-chemical indicators of individual water sources and climate-geological characteristics of the area, we associated the maintenance of good water-ecological status of the studied water sources with precipitation and hydrogeographic features of the wider area of the Ljubija karst spring. The low nitrate content and small fluctuations in other parameters describe the study area as an area with low human impact.
