Abstract:
The aim of this study was to indice evolution of the Olt river water quality in the Ramnicu Valcea industrial aria in the past three years. S.C. Oltchim S.A. discharging wastewater with inorganic and organic load by two final effluent wastewater „Camera de amestec” and „Biological Treatment Station”. The Olt river quality control was realized between Priza Olt Nr.2, upstream, Cremenari and Babeni Marcea, downstream, according with National Legislation. In the downstream sections, in the all three years, was observed increased of the organic and inorganic water pollution in comparison with Section Priza Olt. In all section, -HCH izomer, was situated into limit by 0.02 g/l, 1,2 dichloroethane was falling values in the 10,0 g/l imposed by National Legislation, the other organochlorine chemicals (hexachlorobenzene and 1,2,4 trichlorobenzene) taking values below the detection method. In the last three years there was no heavy metal pollution: mercury, nickel, chromium and cobalt, in three sections. The other factors which affect the Olt river water quality in the Ramnicu Valcea industrial aria, are the hydro-electric plant programs, the quantity of precipitation and the other pollutant accidents.
