The Bengawan Solo which flows through Central and East Java is the largest river in Java Island, and its water is used for various activities such as agriculture, fishery, domestic use, irrigation, and water resources for drinking water. Based on a research carried out in upstream Bengawan Solo, water quality shows a decline indicated by the decrease of dissolved oxygen and increase of BOD and.COD. At location Grogol, dissolved oxygen ranges between 4.4- 7.9mg/Land decreases at Kemiri to 0-6.4 mg/L. BOD at Grogol shows a range between 1.3— 4.5 mg/L increasing to 4.8 —8.1 mg/L at Kemiri. COD range between 3.7-13 mg/L at Grogol increases to 12 - 30 mg/L at Kemiri. In downstream Bengawan Solo, at location Napel and Babat, water quality indicates an increase indicated by increase of dissolved oxygen, and decrease of BOD and COD. The increasing dissolved oxygen and decreasing BOD and COD in downstream area shows that the selfpurification process is happening in the river. The Fecal coli form bacteria at each location is found very high and beyond criteria.
