Springs on Ljubljana polje and Barje area, significant for quantity and quality condition of the groundwater body (Slovenia)
The intergranular aquifer of Ljubljana Field and the aquifer system of Ljubljana Moor are the most important sources of drinking water for Ljubljana. The springs that appear on the area of both groundwater bodies reflect the groundwater status, quantity and quality. The spring water in the Ljubljana Field appears on vowel change of the gravel terrace. We follow them in the lower part of Ljubljana Field aquifer from Fužine to confluence of rivers Sava and Ljubljanica. The spring water directly indicates the condition of groundwater level and the quality. On the Ljubljana Barje there are important springs on the Southern edge. These springs are crucial observation point for the quality and quantity status monitoring of the inflow fro main recharge area of Ljubljana Moor aquifers that are exploited for the water supply system By the detailed analysis of older sporadic measurements of springs in Ljubljana Polje and Ljubljansko barje we were able to assess the changes in theirs trends of quantity and to design the monitoring network of springs that would acquire adequate data for the actual and future assessment of quantity an quality of these groundwater bodies in the frame of all other available and representative observation points.
