Abstract

This study was carried out to document the water quality of Sungai Maong Kiri. The water quality parameter of Sungai Maong that has been chosen in this study is ammoniacal nitrogen. Water samples are monitored and collected by NREB from four selected station which is named N1 station, N2 station, N3 station and N4 station. The analysis of data concentration of ammoniacal nitrogen has been done by using Microsoft Excel. Besides that, in this study, the WASP7 is used to do trial in order to run the water quality simulation program. The high concentration of ammoniacal nitrogen is obtained at the upstream of Sungai Maong Kiri which is occurred at N1 Station. The lowest reading of ammoniacal nitrogen concentration is obtained at N4 station where it is the downstream, of Sungai Maong Kiri. From the study, the water quality of Sungai Maong Kiri is polluted with ammoniacal nitrogen. The source of ammoniacal nitrogen has been identified in this study such as the activity of agricultural development and rapid development. The reading of the concentration is high than the standard of NWQSM for Class IIB. The standard for concentration of ammoniacal nitrogen in water body is 0.3 mg/l. It is not good if the concentration of ammoniacal nitrogen is high in the water and will give negative effect to the habitat in the river especially the growth of unwanted aquatic plants such as algae.
