IMPACT OF WASTEWATER ON SURFACE WATER QUALITY IN KENYIR LAKE BASIN, HULU TERENGGANU

Abstract

Lake water ia an essential resource for livelihood things and the necessary for environment. Human activities affect of water quality, water quantity and alteration the ecosystem system.The sustainable use of lake water resource need more give attention and monitoring programs based on the systematic decision making and management tools. The purpose of this study was to assess the improper wastewater and its effluents discharged into surface lake water resources in Kenyir Lake Basin in order to determine the existing physical environment. A total 21 monitoring stations covering the study area (along the Kenyir Lake Basin) were selected for sampling fieldwork of three season from 2018 until 2019 (Wet Season (Augut 2018), Dry Season (March 2019) and Normal Season (July 2019). There are a few parameters for water quality characteristics were analyzed based on in-situ and ex-situ analysis. As a result, the mean values of mostly water quality paremeters more degrade during wet season compared dry season and normal season. This study proved the water quality status effects on the owing to lack of wastewater management along the lake basin but still in control situation. The policy, environmental knowledge and enforcement triggered for slowing the rate of ecosystem degradation. There are need for a precautionary approach in developing and implementing lake management interventions to protect them to sustain.
