Research to know how much water quality in the River Plumbon, this study using the National Sanitation Foundatio’s – Water Quality Indeks (NSF-WQI) method. NSF-IKA methode Consists of 9 parameters : temperature, turbidity, total solid, pH, DO, BOD, Nitrate, Total Phosphate, and Fecal Coliform. The result monitoring water quality using NSF-IKA metode showed water quality in each river segment is middle category.  Highest values water quality indeks in the point upstream with score 66.06 and the lowest water values water quality indeks in segmen 9 (downstream plumbon river) with score 51.82. The dominant source of pollutants in the River Plumbon sourced from land use is BOD, Nitrate, Phosphate and Fecal Coliform.
