This study was carried out to evaluate the level of two heavy metals (namely lead and cadmium) in water used by food providers in Bahri locality- Sudan. Sixty water samples were obtained from different restaurants and vended food providers, distributed over eight different areas in Bahri locality - Khartoum. A questionnaire was also designed to collect data regarding area, water source and the different purpose for using water. The concentration of the metals was analyzed using Atomic Absorbance Spectrophotometric method. The results obtained showed the presence of Cadmium (Cd) and Lead (Pb) in the water samples with different concentrations. The mean level of Cd in the examined sample was (0.015 ± 0.003 ppm) while the mean level of the lead was (0.21 ± 0.017 ppm) which exceeds the acceptable limit (0.01 ppm). Most of the food providers used one water source for all activities such as drinking, cooking food, washing utensils and hand washing. The higher concentration was found in samples obtained from the Industrial Area, and water stored in pial. Thus, determination of heavy metal levels in the main water systems should be evaluated on routine basis. Availing hygienic water sources and areas for street food providers should also be done by the appropriate authorities.
