An integrated toolkit using multiple methods for determining the potential sources of iron and manganese in groundwater: a case study from the lower Kelantan River Basin, Malaysia
(Springer, 2021) Usman Abdullahi Usman; Ismail Yusof; Muggundha Raoov; Yatimah Alias; Jonathan Hodgkinson; Nurzaidi Abdullah
The application of thin-section petrography, field emission scanning electron microscopy and energy dispersive X-ray analysis (FESEM–EDX), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermo-analysis, and laser Raman spectral analysis methods can be combined to characterize iron-ores and distinguish clay minerals in alluvial soils. The integrated methodology developed for this work provides the basis for a generic mineral characterization toolkit. Five main alluvial soil types have been defined in the upper layer of the lower Kelantan Basin, Malaysia: sand with low clay content, clay sand, sandy clay, mottled clay, and mud-sand.

Comparison of water table fluctuation and chloride mass balance methods for recharge estimation in a tropical rainforest climate: a case study from Kelantan River catchment, Malaysia
(Springer, 2015) Seyed Reza Saghravani; Ismail Yusoff; Wan Zakaria Wan Md Tahir; Zainudin Othman
Estimated groundwater recharge for selected locations in northeast Peninsular Malaysia (North Kelantan River catchment) was determined using the water table fluctuation (WTF) and chloride mass balance (CMB) methods. The WTF method recharge estimates were compared to the CMB method estimates to see if results are similar and the methods can be applied in a humid, tropical region, such as Malaysia.

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.

Detecting and predicting the impact of land use changes on groundwater quality, a case study in Northern Kelantan, Malaysia
(Elsevier, 2017) Tahoora Sheikhy Narany; Ahmad Zaharin Aris; Anuar Sefie; Saskia Keesstra
The conversions of forests and grass land to urban and farmland has exerted significant changes on terrestrial ecosystems. However, quantifying how these changes can affect the quality of water resources is still a challenge for hydrologists. Nitrate concentrations can be applied as an indicator to trace the link between land use changes and groundwater quality due to their solubility and easy transport from their source to the groundwater. In this study, 25 year records (from 1989 to 2014) of nitrate concentrations are applied to show the impact of land use changes on the quality of groundwater in Northern Kelantan, Malaysia, where large scale deforestation in recent decades has occurred.

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.

Effect of 2014 massive flood on well water qualities: A case study on Kelantan River basin, Malaysia
(Polish Academy of Sciences, 2018) Hariz A. Ab. RAHMAN; Noor A. IBRAHIM; Azzmer A. ABDUL HAMID; Tengku H.T. ABDUL HAMID
The effect of physical and biological qualities of wells after submergence was assessed following December 2014 flood in Kelantan. Studies were carried out on a total of 65 wells from 13 stations around Kelantan River basin in which the wells' water were sampled for pH, total dissolved solid (TDS), turbidity and microbial contamination.

Estimating groundwater recharge based on mass balance evaluation of unsaturated zone in a coastal catchment characterized by tropical rainforest weather conditions
(Springer, 2016) Seyed Reza Saghravani; Ismail Yusoff; Wan Zakaria Wan Md Tahir; Zainudin Othman
Estimation of recharge is necessary for evaluating water resources in the north Kelantan catchment of Malaysia due to rapid development and consequently over-drafting of available groundwater. In order to determine the amount of recharge, a study of natural salts (i.e., chloride and sulfate) was conducted to estimate groundwater recharge rates. Studies of the chloride mass balance (CMB) and sulfate mass balance (SMB) were carried out in the unsaturated zone under rainforest weather conditions with a relatively shallow groundwater table.

(Springer, 2001) ABDELATIF MUKHTAR AHMED; WAN NORAZMIN SULAIMAN
Landfills are sources of groundwater and soil pollution due to the production of leachate and its migration through refuse. This study was conducted in order to determine the extent of groundwater and soil pollution within and around the landfill of Seri Petaling located in the State of Selangor, Malaysia. The condition of nearby surface water was also determined.

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.

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.

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.

Groundwater and surface-water utilisation using a bank infiltration technique in Malaysia
(Springer, 2014) Mohd Khairul Nizar Shamsuddin; Wan Nor Azmin Sulaiman; Saim Suratman; Mohamad Pauzi Zakaria; Kamarudin Samuding
Bank infiltration (BI) is one of the solutions to providing raw water for public supply in tropical countries. This study in Malaysia explores the use of BI to supplement a polluted surface-water resource with groundwater. Three major factors were investigated: (1) contribution of surface water through BI to the resulting abstraction, (2) input of local groundwater, and (3) water-quality characteristics of the resulting water supply.
