Assessment of Surface Water Quality in Kakanda: Detection of Pollution from Mining Activities

The study focuses on the assessment of surface water quality mining city Kakanda (Lualaba Province in DRC) to highlight pollution from activity. In addition literature research, identification activities and location rivers streams, methodology adopted consisted analyzing upstream downstream different discharge points final effluents. choice parameters was made according Congolese legislation this subject. Field observations indicated that liquid effluents plants are discharged into natural environment through drains. Chemical analyses have shown waters these drains loaded with metals at concentrations tens times higher than standards. results physicochemical also a deterioration points. level suspended solids reaches 182 mg/l for an acceptable 80 mg/l. concentration cobalt manganese streams receiving reaches, respectively, 0.659 1.709 threshold 0.5 electrical conductivity, chemical composition as well other exploited revealed origin.
