Assessment of water quality a case study of wet pond and detention pond at engineering campus, Universiti Sains Malaysia / Zainulabidin Husain Mohamad

Abstract Disertasi dan kajian ini memfokuskan tentang kelas kualiti air kolam basah dan kolam tahanan yang terletak di Kampus Kejuruteraan, Universiti Sains Malaysia, Nibong Tebal. Parameter indeks kualiti air yang paling asas seperti nitrogen ammonia(AN), oksigen terlarut (DO), keperluan oksigen biokimia (BOD), keperluan oksigen kimia (COD), jumlah pepejal terampai (TSS) dan pH digunakan untuk menentukan kelas kualiti air. Berdasarkan keputusan yang telah diperoleh, didapati bahawa kolam tahanan mempunyai nilai kualiti air yang lebih baik daripada kolam basah di mana semua keputusan data dari kolam tahanan menunjukkan kategori kelas II dengan nilai indeks kualiti air 76.12 hingga 83.33 berbanding kolam basah yang mempunyai kategori kelas III dengan nilai indeks kualiti air 69.43 hingga 71.98 sepanjang kajian dijalankan. Data tambahan semasa musim hujan dan ujian tambahan adalah digalakkan untuk kajian di masa hadapan untuk mengetahui dan memahami dengan lebih mendalam mengenai kecekapan kedua-dua kolam. _______________________________________________________________________________________________________ This dissertation and research focus about the water quality class for wetpond and detention pond that is located at Engineering Campus of Universiti Sains Malaysia, Nibong Tebal. Basic Water Quality Index (WQI) parameters such as ammoniacal nitrogen (AN), dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS) and pH are taken to determine the water quality class. Based on the result that has been obtained, it is found that the detention pond has better water quality than the wetpond as all the detention pond result has falls into class II with the value of water quality index of 76.12 to 83.33 compared to the wetpond that has a class III with the value of water quality index of 69.43 to 71.98 during the research. Additional data on wet season and test are recommended for future research in order to have better understanding of both ponds efficiency.
