| dc.description.abstract | Bedele brewery is one of the industries in the Ethiopian town that releasing high amount of effluent wastewater discharge into the surrounding environment and to the water bodies. The aim of this study is to analyze the effects of Bedele Brewery Factory Effluent on Water Quality and measures taken to encounter the problems, in Bedele District, Buno Bedele Zone, Oromia, Ethiopia. Water samples were taken from the upstream part of Dabana stream, from brewery effluent discharge and downstream after 300 m from the point of effluent discharge to determine the pollution level of Dabana stream water quality exposed by Bedele brewery factory effluent. The water samples were analyzed for physicochemical parameters using DR/2400 and DR 3900 Portable Spectrophotometer by following standard methods and laboratory procedures. The analyzed physical and chemical parameters include; electrical conductivity (EC), turbidity, temperature, TDS, TSS, TS, pH, COD, BOD, DO, NO2 - -N, NO3 - -N, NH3-N, and PO4 3- concentrations were conducted following guidelines of American Public Health Association (APHA, 2017) and (WHO, 2011). Correlations among measured parameters and their significances of water and effluent samples collected were computed using SPSS software (version 22). From the measured values obtained in this study were almost half of the recorded values (turbidity, pH, temperature, TSS, COD, BOD and DO) were above the recommended values and the rest measured parameters were within both the Compulsory Ethiopian standard (CES, 2013) and World health organization (WHO, 2011; WHO, 2017) guidelines. Because of inadequate treatment of the effluent discharge from the factory & infrequent management of treatment plant as recommended standards this studied stream indicates polluted for domestic purposes. It also indicates the effects of discharging of effluent released from the brewery effluent are responsible for the high level of water contamination around the discharge point. Therefore, the waste water released from Bedele Brewery factory to the Dabana River affects the water quality standards and the responsible regulatory bodies (Environmental Protection Authority) should have taken measures in order to protect the river from such pollution problems. Thus, it calls for appropriate intervention, including awareness creation work and improving the existing infrastructure. | |
