Measuring the Physico-Chemical Impact of Wastewater from the Open Sewer in an Industrial Area: Case of the Kossodo Industrial Area in the City of Ouagadougou in Burkina Faso

Wastewater from industrial units in the Kossodo district in the city of Ouagadougou has a physicochemical impact on the environment and the population. For several years the Kossodo area was famous for the effects of wastewater from industrial units on the environment (a foul odor). We took samples from various points of the open canals in order to determine the physico-chemical parameters of this wastewater. This choice was guided by a concern to measure the physico-chemical impact of wastewater from the open sewer in the industrial zone of Kossodo in the city of Ouagadougou on the one hand and to show the danger represented by this wastewater from industrial units on the environment and public health on the other hand. The objective also guided the choice of the parameters retained for the measurement of the physicochemical impact of the industrial units wastewater of the open sewer of Kossodo zone in the city of Ouagadougou: MES, DCO, BOD5, pH, Potassium, Sodium. The results show that the wastewater from the open sewers of the industrial units of Kossodo in the city of Ouagadougou, has a high physicochemical parameter content than the authorized discharge standard.
