This research is done in 5 segments of Wonokromo River. The water quality parameter that is examined are temperature, pH, DO, BOD, TSS, COD, NO3-N, PO4. The quality status of Wonokromo River which is calculated using STORET method shows that the river is moderately polluted. While the result from PI method shows that the river is lightly polluted. The previouse research had not done further by different considerations in scoring the parameter and different data inputted to the calculation.
