The main goal of this experiment was to evaluate the effect of broiler strain and source of drinking water on some performance traits (body weight and carcass traits). Sample of water were taken from two different location sources, Giza governorate (as Nile water) and Qalubia governorate (as well water or ground water). Three different broiler strains were used in this study (Arbor acres, Hubbard and Cobb). Lead concentration (as a heavy metal element) and bacteriological analysis (total bacteria and fecal coliforms) in both water and carcass were carried out. The main results obtained can be summarized as follow: Arbor acres strain recorded the heaviest body at most ages compared to the other strains, the difference was highly significant at 5 and 6 weeks of ages. Total bacteria were significantly high in ground water compared to Nile water. Conversely, Coliforms bacteria count was significantly high in Nile water compared to ground water source. Regardless strain type, high positive correlation between lead concentration in drinking water and lead concentration in liver, kidney and carcass weight was observed
