ABSTRACT
The aim of this study was to present evolution of the Olt River water quality in the Ramnicu Valcea industrial aria in the last four years (2008-2011). This study was realized in order to determine the degree of the water pollution in the industrial platform Ramnicu Valcea, Romania. The main factors which affect the Olt River water quality in the Ramnicu Valcea are: industrial activities, the hydro-electric plant programs, the quantity of precipitation and the other pollutant accidents. According with our results, in the last four years there was no heavy metals pollution: mercury, nickel, chromium and cobalt, in all three sections of this study. In all section, γ-HCH isomer, was situated under limit of 0.02 μg/l, 1,2 dichloromethane was under limit of 10,0 μg/l imposed by National Legislation, the other organochlorine chemicals (hexachlorobenzene and 1,2,4 trichlorobenzene) taking values below the detection method.
