Natural waters such as rivers are environmental components that need to be considered especially regarding the quality of river water. River water quality can decrease because landuse change as a form of increasing human activity. The purpose of this study is to assess the river water quality of the Ci Lutung Watershed, specifically the Ci Jurey-Sub-Watershed and Ci Deres Sub-Watershed. To assess the quality of the water, a water sample is taken directly from the specified river body. The water quality parameters tested consisted of TDS, pH, conductivity, and turbidity as physical parameters, and nitrate, phosphate, sulfate and chloride as chemical parameters. This water quality assessment is carried out using the STORET method, which is comparing the results of parameter tests with Class III Water Quality Standards as determined by Indonesian Government Regulation No. 82/2001. This research also identified the relationship between landuse and lithology as a watershed characteristic with the river water quality. To be concluded, the water quality of the Jurey River and the Deres River is categorized as light polluted according to the STORET calculation. Also, the water quality in both rivers are spatially influenced by each watershed's characteristic. TDS value is calculated high because its lithology-age of oligocene Tertiary rocks, and nitrate value is calculated high because it is influenced by agricultural activities.
