Abstract:
This study was conducted in May 2013 in the waters of River Tarai District of Kampar Regency Mines. While the analysis of parameters of BOD, COD, TSS and ammonia performed at the Laboratory of the Department of Public Works, Pekanbaru. This study aims to determine the impact of the disposal of liquid waste on water quality River Village Tarai Tarai district of Kampar Regency Mines aspects of physics (pH, temperature, flow velocity, TSS, depth) and chemical (DO, BOD, COD, Ammonia. From the research this can be concluded that, wastewater effluent know an impact on the physical and chemical quality of river water Tarai as TSS increased, the depth and speed of flow, BOD, COD, pH and NH3. overall impact of discharges liquid waste into the waters of river Tarai still not exceed the assimilation capacity of the river Tarai based on the availability of dissolved oxygen conditions which still meets or is above the minimum requirement of fish life, which is 3 mg /l.
