Simulation Of Groundwater Flow And Pollutant Transport For Alluvial Aquifer In Kampung Tekek, Tioman Island

Abstract

Tioman Island Is Situated In The East Coast Of Peninsular Malaysia. With Rapid Growth In Tourism Industry, The Demand For Water Supply Is Expected To Increase In This Island. From Previous Studies, Groundwater Was Found To Be A Potential Source Of Water. A 3-Dimensional Numerical Modelling Software (Visual MODFLOW) Is Used To Simulate The Groundwater Flow And Pollutant Transport Of The Aquifer In Kampung Tekek, For The Prediction Of Available Yield Of Groundwater, And Also For Studying The Migration Of Potential Contaminant Source, I.E. Nitrate, Due To The Withdrawal. The Groundwater Flow Simulation Results Showed That The Aquifer Is Capable Of Pumping 4000 M3/Day. Results Of Pollutant Transport Modelling Showed That The Estimated Concentration Of Nitrate In The Pump Well Is Generally Low And Complies With World Health Organisation (WHO) Standard For Drinking Water.
