The Study of River Water Quality in Water Pollution Control: Case Study ofTalawaan River, North Minahasa District, North Sulawesi Province

Abstract

This research was conducted to assess the quality of river water in the context of controlling water pollution in the TalawaanRiver in North Minahasa Regency, North Sulawesi Province. This research is a descriptive-quantitative research. The fieldresearch was carried out in the Talawaan River, North Minahasa Regency. Water quality measurement includes physicalparameters: TSS, and chemical parameters; BOD and COD were carried out at five monitoring points. The results showedthat the content of BOD, COD, and TSS in Talawaan River water met the water quality standards (Type B water). Thecharacteristics of the waste (BOD, COD and TSS), the concentration values of BOD, COD and TSS concentration values donot exceed the quality standard according to their designation. The potential for domestic waste pollution load reaches 1,495kg/day from a total population of 16,040 people. The status of Telawan River water quality is classified as ”lightly polluted”based on the studied parameters; there are several other variables that were not included in this study, such as T-P, TotalColi, and Fecal Coli
