N2  - Malaysia has been undergoing development in leaps and bounds over decades. However, concerns have been raised nowadays about the quality of the environment, the greater risk of development. Water pollution is undoubtedly one the most concern issues. This study determines the role of aquatic plant Eichhornia crassipes in improving water quality due to petrochemical efiluent. Gebeng has been chosen for the study area because it is full with many industries. Water sample is taken from sungai kupak which is in Gebeng because its location near to industrial area. Concept of free water surface wetland (FWS) is applied in this study. Water sample then is tested to produce the water quality data for Sungai Kupak.Water sample is also test with the combination of Free water surface wetland (FWS) and Eichhornia crassipes plant to determine removal efficiency within the experiment parameter. From the overall experiments of water quality, the water sample can be categorized in class IIA and class lIB based on the Biochemical Oxygen Demand (BODs) and pH result. These classes are referring to Interim National Water Quality Standards for Malaysia Class ITA stated that conventional treatment required and class 1m stated recreational used with body contact. From the ovemll experiments of wetland performance, Free Water Surface Wetland (FWS) are effective in removing ion Plumbum and Biochemical Oxygen Demand (BODs) which is 70.55% and 75% removal efficiency. Free Water Surface Wetland (FWS) is effective in neutralizing water which is from pH range of 8.60 to 7.85. It also makes the water become clear in tenn of turbidity which is from 16.0 NTU to 13.4 NTU. Removal efficiency of the Free Water Surface Wetland (FWS) in this study did show an effective performance as predict in outcome result. Presence of Eichhornia crassipes also increase the ability of Free Water Surface Wetland (FWS) to decrease BODs concentration of water sample as predicted. -Author
