Controlling factors of groundwater hydrochemistry in a small island's aquifer
(Springer, 2007) A. Z. Aris; M. H. Abdullah; A. Ahmed; K. K. Woong
Factor analysis was applied to the hydrochemical data set of Manukan Island in order to extract the principal factors corresponding to the different sources of variation in the hydrochemistry. The application of varimax rotation was to ensure the clear definition of the main sources of variation in the hydrochemistry. The geochemical data of dissolved major, minor and trace constituents in the groundwater samples indicates the main processes responsible for the geochemistry evolution. By using Kaiser normalization, principal factors were extracted from the data for each location.

Water quality of streams and wells of north Perlis: a comparative analysis
(Environmental Management Society Malaysia, 2007) Wan Ruslan Ismail; Haslina Sarju; Mashhor Mansor
Water resources in catchment area came from various sources. Water from the surface infiltrate and leached down to the ground water. Land use activities on the surface will affect water quality of both surface and underground water. Underground water has been use by Malaysian as their water resources. Perlis and Kelantan are the two states in Malaysia that have a lot of wells still in use for water supply especially during dry season. This study investigates the spatial and temporal changes in water quality of surface and ground water of north Perlis from July 2001-December 2001.

Evaluation of yield and groundwater quality for selected wells in Malaysia
(Universiti Pertanian Malaysia Press, 2009) Thamer Ahmed Mohammed; Abdul Halim Ghazali
In Malaysia, the use of groundwater can help to meet the increasing water demand. The utilization of the aquifers is currently contributing in water supplies, particularly for the northern states. In this study, quantitative and qualitative assessments were carried out for the groundwater exploitation in the states of Kelantan, Melaka, Terengganu and Perak. The relevant data was acquired from the Department of Mineral and Geoscience, Malaysia.

Extenuation of saline solutes in shallow aquifer of a small tropical island: A case study of Manukan Island, North Borneo
(Thai Society of Higher Education Institutes on Environment, 2010) Ahmad Zaharin Aris; Mohd Harun Abdullah; Sarva Mangala Praveena; Mohd Kamil Yusoff; Hafizan Juahir
Intensive exploitation of groundwater from Manukan Island, s aquifer has disturbed the natural equilibrium between fresh and saline water and has resulted in the increase of groundwater salinity and the hydrochemical complexities of freshwater-seawater contact. It was observed that the mixing between freshwater-seawater has created diversity in the geochemical processes of Manukan Island, s aquifer and altered the freshwater and seawater mixture away from the theoretical composition line.

Deterioration of groundwater quality in the vicinity of an active open-tipping site in West Malaysia
(Springer, 2010) Bahaa-eldin E. A. Rahim; I. Yusoff; A. R. Samsudin; W. Z. W. Yaacob; A. G. M. Rafek
There is an urgent need for characterization of leachate arising from waste disposal to ensure a corresponding effective leachate management policy. Field and laboratory studies have been carried out to investigate the impact of municipal landfill leachate on the underlying groundwater at a site in West Malaysia.

Extent and severity of groundwater contamination based on hydrochemistry mechanism of sandy tropical coastal aquifer
(Elsevier, 2012) Noorain Mohd Isa; Ahmad Zaharin Aris; Wan Nor Azmin Wan Sulaiman
Small islands are susceptible to anthropogenic and natural activities, especially in respect of their freshwater supply. The freshwater supply in small islands may be threatened by the encroachment of seawater into freshwater aquifers, usually caused by over pumping. This study focused on the hydrochemistry of the Kapas Island aquifer, which controls the groundwater composition. Groundwater samples were taken from six constructed boreholes for the analysis and measurement of its in-situ and major ions.
