Abstract

Well water is a renewable natural resources and one of the drinking water sources for many areas in Kelantan. The assessment of well water quality is very important in evaluating the suitability of the water for drinking and other domestic purposes. Major ions such as K⁺, Ca²⁺ and Na⁺ in well water may originated from dissolved mineral composition of the underground rocks and soil mainly granitic in origin. The objective of this study is to determine the concentration of K⁺ and Ca²⁺ using Energy Dispersive X-ray Fluorescence (EDXRF), whereas F^-, Cl^- and SO₄^2- were determined by ion chromatography (IC) in the well water collected from various districts of Kelantan. The well water samples were collected from Gua Musang, Jeli, and Tanah Merah districts. In situ measurement of water quality parameters such as temperature, pH, salinity, dissolve oxygen (DO), conductivity, turbidity and total dissolved solids (TDS) were conducted using YSI portable multi-probes meter. The concentrations of K+ and Ca²⁺ were measured and found in the range of 227.89 – 691.44 and 0 – 36.71 ppm respectively. The concentration of Cl^-, SO₄^2- and F^- were measured and found on the ranged of 2.08-17.0, 0.71-13.10 and 0 – 3.54 ppm respectively.
