Groundwater is one of the major drinking water sources in Bidong Island, Terengganu.<br />

This study was conducted due to the insufficient information regarding on the trace<br />

metals content in groundwater. In total, 12 types of metals (Li, B, Na, Al, Ca, Mn, Fe,<br />

Ni, Zn, Sr, Ba and Pb) were measured in groundwater samples collected from five<br />

sampling stations (well) in June, July, August, September and November 2017. The<br />

ICPMS was used to analyse trace metal concentration in groundwater samples. The<br />

trace metals concentration was arranged in descending order:<br />

Na>Ca>Al>Sr>Ba>Fe>B>Mn>Zn>Li>Ni>Pb. Sodium was the highest trace metal in<br />

groundwater samples due to the effect of saline water intrusion. Other than Al, all the<br />

trace metals were within the standard that established by WHO. Thus, it was assumed<br />

that the groundwater at Bidong Island is safe to be consumed.<br />
