Groundwaterof North West Bank in Palestine was assessed for pollution with trace metals byICP-MS. The samples were analysed for theirpH, electrical conductivity, total dissolved solids, and different trace metalscontent. The pH, electrical conductivity, and total dissolved solids of allwater samples were found to be within the US Environmental protection Agencylimits. Results showed that the concentration of nine trace metals Cr, Mn, Ni,Cu, Zn, Mo, Pb, Cd, and Al is within the WHO limits in drinking water 50, 500,20, 2000, 3000, 70, 10, 3, and 200 ug-L, respectively, however six metals ofthem Cr, Mn, Ni, Cu, Mo, and Al were detected in 100% of the samples, whilePb, Cd, and Zn were detected in 80%, 60%, and 20% of the samples, respectively.On the other hand, Tl which is a very toxic heavy metal with allowed WHO limitsof 0.01 - 1 ug-L is detected in 100% of the water samples analysed with a range of 0.02 - 0.12 ug-L. It indicatesthat such concentration levels of Tl would be harmful to the human being drinkingthe water. In general, 82% of all samples analysed contained one or more of the12 metals studied each in varying concentration. Results of this study suggesta possible risk to the people of the study area given the toxicity of heavymetals, and the fact that for many people in the study area, groundwater is amain source of their water supply.
