Drinking water quality has been greatly affected as a result of biohazards and industrialization. There are many microorganisms can initiate waterborne infections including enteric and aquatic bacteria that are strongly resistant to most of disinfectants. Beside, heavy metals can pollute drinking water either through improper industrial waste drainage systems or inadequate monitoring of the plumbing integrity, heavy metals have a great hazard on health if exceed the permissible limit. This study aimed to qualitatively screen the presence of any waterborne bacteria as well as to measure the concentrations of some heavy metals in drinking water samples from different localities in KSA. Samples were collected from industrial and suburban – non industrial – cities, as well as different sources and were analyzed for Manganese (Mn); Cupper (Cu); Cobalt (Co); Cadmium (Cd); Zinc (Zn); Mercury (Hg); Nickel (Ni); Arsenic (As) and Lead (Pb) using Inductively coupled Mass Spectrometer and their concentrations were compared to the permissible limits defined by WHO guidelines. Results showed no microbial contamination, while the variation of concentrations of heavy metals was clear among samples from different localities. Only (As) and (Hg) concentrations exceeded the permissible level and the highest levels were detected in the samples driven from the industrial provinces, indicating the improper disposal of industrial waste. On the other hand, variation in heavy metals concentration among the samples that were collected from different sources indicates the hygienic status of the commercially produced drinking water, whereas the lowest concentration of Cd, Pb, Mn and Cu were detected in bottled water samples. The aim of this study is to determine the incidence of microbial growth and/ or heavy metals in drinking water as environmental contaminants that may lead to many expected health hazards.
