In the present study, we carried out a bibliographic and analytically research on the various sources of pollution of wade Beht, by analysing the physicochemical parameters (pH, temperature, conductivity and turbidity) and biological parameters (DCO and DBO5) in water samples taken at five sampling points, to determine the degree of pollution. The results of the analysis of the physicochemical and biological parameters envisaged in this work were recorded in the following order: 7.6 ≤ pH ≤ 8.6, 20 °C for temperature, the conductivity was between 2900 and 3000 μS/cm for the first four sampling points while that measured for the discharge of the SURAC was obtained in the order of 3100 μS/cm. The control of the general parameters of the pollution at the point of evacuation point of the releases of the industry SURAC displayed the results in the order of 300 mg O2/l for DCO and 120 mg O2/l for DBO5. From the results obtained at the end of this study, we found that the measured values are higher than those indicated in the standards of the surface water quality grid, which means that the quality of the bottom waters wade Beht varied from bad to very bad.
