Abstract

Petapahan river, 6 Km long is one of river that is an administrative district in the region ofGunung Toar. This river has long been used for many activities by people who live along theriver. The study was conducted at the Petapahan River in November 2011. The aimof thisresearch is to determine the quality of the river in terms of parametersof Physics, Chemistryand Biology compared to pp.82 of 2011 on Water Quality Management and Air pollutionControl as well as to determine the appropriateallocationofriver waterqualityThe methodsusedin this study wasasurveymethodas PurposiveSampling.
