Abstract Analysis of river water quality and water quality status refers to Government Regulation No. 22 of 2021 on the Implementation of Environmental Protection and Management and Minister of Environment and Forestry Regulation No. 27 of 2021 on the Environment—analysis of river water quality status using the STORET method. River water quality data is described at four water sampling locations monitored for three years during the dry and rainy seasons. The river method’s analysis results using the STORET method obtained values between -3 to -43 in the dry season and rainy season, with river water quality status from “lightly polluted” to “heavily polluted.” The concentration values of the parameters BOD, COD, total phosphate, and faecal coliform exceeded the class 1 and class 2 quality standard thresholds, concluding that Kapuas River water is not recommended for use as a raw water source for drinking water and water recreation facilities The importance of synergy between relevant stakeholders and community involvement is a solution for water resources protection efforts.
