Assessment of Ogan River Water Quality Kabupaten OKU South Sumatera by NSF-WQI Method

A Study of physicochemical and microbiology analysis in Ogan River Kabupaten Ogan Komering Ulu was carried out in Mei-June 2016. The purpose of this study was to determine the water quality status of Ogan River in Kabupaten OKU South Sumatra. There are several methods can be used in doing the assessment for water quality of a river. The National Sanitation Foundation Water Quality Index (NSF-WQI) will be used in this study. Water quality status was studied at six selected stations to represent different localities with varying anthropogenic discharge. Water samples were taken by purposive sampling method. Physicochemical and microbiology parameters of samples were measured pH, temperature, Turbidity, Total Suspended Solids, Dissolved Oxygen, Biochemical Oxygen Demand, nitrate, Phosphate, and Fecal Coliform following standard method. The result is the river water quality status is medium; the value ranged 56-57. Based on these indices it is concluded that the anthropogenic activities along Ogan River affected the quality of water Ogan River.
