From this research, a pollution index values are calculated at the BGR point 1 is 8,17; BGRpoint 2 of the resettlement 9,17; BGRpoint 3 of the resettlement 5,17; BGRpoint 4 of the resettlement 7,03 ; and at that BGRpoint5 is 7,48. Based on KepMen LH No. 115 in 2003 about the determination of the Status of Water Quality Guidelines, the value of the IP is at 5,0 < PIj ≤ 10 categorized into polluted medium. So the water quality status at all Banger River the segmentation categorized polluted medium.
