Assessment of trace metals in ground water used for drinking purposes in Riyadh region in the kingdom of Saudi Arabia was carried out. Samples were collected from 25 wells supplying drinking water to the inhabitants in the region. All samples were analyzed for 8 trace and macro elements (Al, Cd, Cr, Cu, Fe, Ni, Pb and Zn) using Atomic Absorption spectrophotometer. The minimum and maximum trace metals concentrations in different areas for Cr, Cu, Fe and Zn ranged between BDL to 0.561 ppm, 0.089 to 0.989 ppm, 0.041 to 1.700 ppm respectively Ni, Al, Pb and Cd were also measured but were found below detectable level (BDL) in the entire study period. The results were compared with the World Health Organization (WHO) and Bureau Indian standard (BIS) values. It reveals revealed the presence of some heavy metals in few ground water samples and hence refers heavy metal contamination of ground water sources. The result shows that most of the groundwater is deteriorated less than the permissible limit of WHO. It is recommended that an adequate and suitable treatment must be applied to the wells having elevated concentrations of the metals and supplying drinking water to the consumers.
