The springs from the ”Făget” area of Cluj.

Summary/Abstract: To the south of the city of Cluj, in the perimeter called “Făget”, there are numerous springs often frequented by locals. From a geological point of view, there is a great variety of rocks of different ages and characteristics. The waters cantoned in these geological structures appear on the surface along the valleys, on the slopes or even in the unevenness of the interfluves. Their existence was facilitated by vertical erosion processes and mass movements of the material. Through the inventory of the area, 28 sources were identified and located. They can be divided into several categories: with drain, wells, inactive, dried, captured. Spatial coordinates were determined for each source. Where possible, the flow rate, temperature and concentration of dissolved in water substances were measured. There is a large gap in flow variation, relatively constant temperatures and wide limits of TDS values. The expansion of the urban area involves potential risks of a quantitative and qualitative nature.
