.0 CONCLUSION
Generally, the water quality of Sungai Dekong was considered more polluted than Sungai Dawai as showed by the diversity, abundance and biological indices of benthic macroinvertebrates. EPT index and EPT ratio to total at Sungai Dawai were also higher than Sungai Dekong. The highest diversity and richness was at the end of Sungai Dawai (ST5) and the lowest was at Sungai Dekong (ST1). Twenty five percent of the benthic macroinvertebrates was Elmidae which was in abundance at Station 5, followed by Chironomidae (18%) which was in abundance at Station 1 (Sungai Dekong) and Station 5 (Sungai Dawai). A further study on benthic macroinvertebrates at Sungai Dawai and Sungai Dekong was recommended as there are many river tributaries connected to Sungai Dekong which are believed to be the pollution source to Sungai Dekong. Thus, more data was needed to help the authority to restore, monitor and sustain the surrounding
