These sources are prone to elevated levels of metals and metalloids that may cause exposure of the general population when the treatment of the water is inadequate. This work presents a simple method based on EPA Method 200.8 for the determination of total concentrations of arsenic (As), cadmium (Cd) and lead (Pb) in drinking water using inductively coupled plasma-mass spectrometry (ICP-MS) as the element-selective detector. This was applied in the determination of these elements in the water supply in Metro Manila, Philippines. The method detection limits were 0.095 μg L-1 , 0.043 μg L-1 , and 0.114 μg L-1 for total As, Cd and Pb, respectively. The method was validated using National Institute of Standards and Technology (NIST) 1643e certified reference material for trace elements in water and determined values were 60.4 ± 0.5 μg L-1 , 6.7 ± 0.1 μg L-1 , a...
