Sg. Kejapil water catchment and miri – suai pilot project (mispa) of sarawak integrated costal zone management (izcm) : a study on ammonia nitrogen and nitrate nitrogen concentration level for sg.kejapil raw water

The current development in the coastal zones of the state of Sarawak is characterized by insufficient integration, coordination and cooperation amongst federal, state and local governments and other stakeholders. The direct implication of poor coordination may give rise to complicated and undesirable negative environmental impacts on the state coastal zones. This study is focused on the Sg. Kejapil water catchment, in Miri Division. The abundant natural resources within the water catchment area such as timber, water and its relief characterized by undulating plain attract many stakeholders. The uncontrolled human activities within the water catchment area have resulted in negative environmental impacts on Sg. Kejapil water catchment and its raw water. This study has confirmed that there are negative environmental impacts on Sg. Kejapil raw water due land development sited in the upper region of the catchment. Results show that the concentration levels of the ammonia nitrogen and nitrate nitrogen in Sg. Kejapil raw water are increasing from 1997 to October 1999.
