The status of water quality need to be known In order to know whether It can be used or not for daily consumption. The aim of the research is mainly to establish the water quality status of Surabaya River by both storet system and pollution index. The research impleanted by field survey and the sample collected was exemined in situ and in lavoratory. The removal of water sample from Surabaya River was conducted based on integrated sampling.The result of the research indicated that the status of water quality of Surabaya River has been heavy polluted a long the watershed with -80 up to -104 of Index STORET value. However, the different results was obtained if the evaluation Is based on Sumitomo and Nemeros. The level pollution of Surabaya River based on Pollution Index revolved between light polluted up to moderate polluted with 2.03 to 5.59 of pollution index value. The result showed that the Pollution Index Sumitomo and Nemerow have higher tolerance for pollution than that of STORET Index.
