AB  - Introduction: Quality drinking water should be free from harmful levels of impurities such as heavy metals and other inorganic elements. Methods: Samples of tap water collected from 24 locations in Peninsular Malaysia were determined
for inorganic element content. Minerals and heavy metals were analysed by spectroscopy methods, while non-metal elements were analysed using test kits. Results: Minerals and heavy metals determined were sodium, magnesium, potassium, calcium, chromium, manganese, iron, nickel, copper, zinc, arsenic, cadmium and lead while the non-metal elements were fluoride, chloride, nitrate
and sulphate. Most of the inorganic elements found in the samples were below the maximum permitted levels recommended by inter-national drinking water standard limits, except for iron and manganese. Iron concentration of tap water
from one of the locations was higher than the standard limit. Conclusion: In general, tap water from different parts of Peninsular Malaysia had low concentrations of heavy metals and inorganic elements.
