Abstract:

The paper present the water quality from Brasov area including Codlea district. The water resources of Codlea include the underground-groundwater and deep waters and the surface waters represented by the network of rivers that cross the territory of the locality. Groundwater resources fall into two categories, namely: the mountainous area (where the active layer is deep) and the shallow area (consisting of newer detrital rocks, which allow the formation of rich aquifer horizons, with appropriate qualities for different uses. Groundwater is found at depths between 1-2 m to 10-15 m with normal flow and mineralization of 0.5 g/L. At the base of Măgura Codlei there are several springs, the one on "Valea Caldă" with a constant temperature of 18℃, arranged for recreation and the springs on "Mărul Dulce". This paper consists in analysis of the influence of ecosystems: especially the mountain "Măgura Codlei" and "Codlea Forest", on water quality as well as evaluation of chemical pollutants impact. The physical and chemical indicators potentiometric pH, electrical conductivity, nitrate concentration(ppm), metals concentration will be determine in a further study. In addition the monitoring of heavy metals will be investigate by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) to determine concentration of the metals As, Cd, Cu, Fe, Pb, Co, Cr, Mn, Zn, Se, Co.
