Item Open Access Multivariate statistical analysis for identifying water quality and hydrogeochemical evolution of shallow groundwater in Quaternary deposits in the Lower Kelantan River Basin, Malaysian Peninsula(Springer, 2016) Nur Hayati Hussin; Ismail Yusoff; Wan Zakaria Wan Muhd Tahir; Ibrahim Mohamed; Adriana Irawati Nur Ibrahim; Adzhar RambliA long-term hydrogeochemical data set is used in this study to evaluate the water quality and hydrogeochemical evolution of shallow groundwater in a Quaternary deposit. A multivariate statistical method, hierarchical cluster analysis (HCA), is applied to overcome the problem of a large number of data points in the integration, interpretation and representation of the results. HCA is applied to a subgroup of the hydrogeochemical data set to evaluate their usefulness to classify the groundwater bodies.Item Restricted Natural sources of iron and manganese in groundwater of the lower Kelantan River Basin, North-eastern coast of Peninsula Malaysia: water quality assessment and an adsorption-based method for remediation(Springer, 2021) Usman Abdullahi Usman; Ismail Yusof; Muggundha Raoov; Yatimah Alias; Jonathan Hodgkinson; Nurzaidi Abdullah; Nur Hayati HussinShallow groundwater resources in the lower Kelantan River Basin show anomalously high concentrations of iron and manganese. In some cases, other transition metals and metalloids such as arsenic are also present at elevated levels. Coupled mineral stability and aqueous geochemical models were used to determine the possible sources of iron and manganese in the groundwater.
