Did you know?

That chert, chert nodule is 1. black, brown or grey rock, consisting of very fine-grained silica, that occurs as horizons of nodules and discontinuous bands, generally less than 200mm thick, within many limestones. it is very hard and almost insoluble in water, so commonly it projects from cave walls where it forms passage or shaft ledges and waterfall lips [9]. 2. light-cream or gray to black rock composed of silica, found occurring as nodules or layers in limestone, or as a replacement of limestone [10].?

DIRECTIONS AND DYNAMICS OF FLOW AND TRANSPORT OF CONTAMINANTS FROM THE LANDFILL NEAR SEŽANA (SW SLOVENIA)
Abstract:

The characteristics of flow from the landfill near Sežana in the area of Kras were studied by the use of tracer test. In well permeable fissure on the karren surface near the landfill the fluorescent dye uranine was injected in order to study the directions and velocities of its flow through the karst aquifer. Monitoring of tracer concentrations in the period of one year and a half enabled us to make some conclusions about the dynamics of groundwater flow in the directions towards the Timava, Brojnica and Sardoč springs. Detailed observations were organised also at the Klariči pumping station, which is the main source of drinking water for the Kras region. Increased concentrations of tracer were measured only during extremely high waters. Different explanations are possible, but we can not exclude the possibility of a weak, not permanent underground water connection with the landfill. Calculation of the amount of recovered tracer confirmed the main flow direction towards the Timava springs (recovery rate 93%) and a secondary direction with lower flow velocity towards the Brojnica and Sardoč springs. Outflow through the Klariči pumping is estimated to only 0.003% of injected uranine.
