Malaysia is a rich country in water resources through rivers, but majority the rivers are continuously increased in contamination. Current status of river water quality are no longer to be consume directly such as outdoor activities of swimming, fishing or recreational activities on the river, due to no longer healthy of water resources and the river water is contaminated which could cause dangerous diseases. At these circumstances, river water pollution is expected and detected caused by point- and non-point source contamination. The point source pollution is originated from central wastewater treatment, manufacturing, agricultural and industrial waste as well as animals farming activities. Meanwhile, the non-point source pollution is reported from agricultural activities and the mechanism of surface runoff. Therefore, based on the standards of the Water Quality Index (WQI) and the Interim National Water Quality Standard (INWQS) designed by DOE Malaysia, the water quality level of UTM River can be determine by examine on six basic water quality parameters, namely ammonia nitrogen, BOD, COD, suspended solid, pH, DO, and temperature. In conclusion, without proper monitoring, the level of river water quality are suspected to continuously decrease and sustainable development will be necessarily required to maintain the biological ecosystem in surrounding environment.
