Assessment on the Impacts of Industrial Effluents to the Water Resources in Dar es Salaam Tanzania.

The study examined the physical and chemical parameters of wastewater, their impacts to the surrounding community and challenges of wastewater management at Mikocheni industrial area, Dar es Salaam. It employed both quantitative and qualitative methods. 60 questionnaires were collected from respondents and 56 samples were collected from one point that most of wastewater from industries do discharge into. The findings have revealed that the industrial effluents contained physical and chemical parameters. The level of all physical parameters with COD and BOD5 were not within the permissible limits for TBS standard for Municipal effluent discharge, hence contaminates nearby environmental resources. Further the findings indicated that there were myriads of challenges in wastewater treatment because of the poor effluents management systems of the industries. It was therefore, recommended that, Industries at the study area must have proper wastewater treatment facilities in their premises so as to safely discharge treated wastewater to the receiving bodies. There must be enforcement of rules and regulations by responsible authorities on wastewater discharge such authority as the National Environment Management Council (NEMC). Industrial owners who will fail to adhere to the environmental rules, their licenses need to be revoked, heavy metals should be handled well since their excess in environment may pose health side effects like cancer whereby the number of patients suffering from cancer increases daily also the study recommended that the local environmental committees should be involved in reducing effects of industrial effluents.
