Cikapundung River is located through Bandung City, it’s one of stream which flow to Citarum Watershed. Several studies on conservation modelling and planning have been carried out, but there are uncompleted data about water quality of Cikapundung River, therefore study on water quality assessment is required. Data was collected in 26 points starting from upstream in Maribaya and ends in the downstream in Bojongsoang, Bandung City. Parameters that recorded are pH, temperature, conductivity and dissolved oxygen (DO). Result showed that DO levels begin to drop under 5 mg/L in 17000 meters or 17 kilometers from a upstream, the increasing of human activity of this point influenced the level of dissolved oxygen in the surface water, pH ranged from 6.7 to 9.67, while conductivity range about 66 to 410 µS/cm. Sampling locations and land use was determining factors that influenced dissolved oxygen concentration, pH and conductivity values, while climate affects temperatures around the sampling point.
