Abstract:
Research on the effect of chemicals on the water quality of the Rusweri river in Supiori Regency has been conducted. The inventory plan of the river as a provider of raw water in Supiori Regency will begin in 2020, and the Rusweri river is one of the candidates to be used, it will be seen using its green water for microbiological assistance that can be researched the Rusweri river. This study uses a descriptive method that explains the water quality of the Rusweri river with physical and chemical monitoring parameter methods for each place in the Rusweri river. The results of this study contain several chemical and physical parameters that exceed the quality standard threshold. Increased concentrations of parameters PO4¯, Fe, F¯, COD, and BOD from upstream to downstream due to the river bed structure that already contains particular metal contents and also the influence of organic and microbiological concentrations that enter through the addition of secondary rivers on the body Rusweri river. Calculation of river pollution index results in an average of mildly polluted status, which is dominated by phosphate parameters
