Abstracts

Aims: Unrefined industrial sewerage and unplanned water use changes groundwater quality and pollutes environment which is vulnerable to Langat basin of Malaysia. This research has aimed to find the water pollution trend due to urbanization by analyzing the hydrogeological condition and ground water quality status of Langat basin giving emphasis on Kajang and Semenyih town.

Study Design: Geological, hydrochemical and statistical analysis.

Place and Duration of Study: Borehole log, pumping test and groundwater chemistry data were collected from Mineral and Geosciences Department, Selangor for two towns Kajang and Semenyih. Study areas are in Kenny Hill formation and the wells pumping water from four types of rock formation. Ten years data variation on population and water quality were used.

Methodology: Three types of analyses were performed by using collected data. The subsurface geological analyses, well water chemistry interpretation with Hydrochemical facies analysis and statistical analyses. All the analyses were done by using different software.
