Chemical, Physical and microbial appraisal of bottled water in Iraq

Abstract

There has been a growing concern about the quality of bottled water; in as much to the increased bespoke of-this product so to evaluate the quality of bottled water in local markets in Baghdad, This study was investigated. Fifteen types of bottled water were chosen randomly from local markets for analyses. Physical, chemical and microbial properties of all samples were appraised comprising turbidity, PH, concentration of Ca, Mg, Cl, Pb, total bacteria counts, total coliform count, fecal coliform, E.coli and protozoa. The results obtained were compared with the world health organization for drinking water and the standard specification for Iraqi drinking water. The turbidity for all samples was less than 1(NTU). The range of the PH value was (7.5-8.5) Concentration of Ca, Mg, Cl, Pb were (0.1604-9.223), (0.117-14.009), (2.9-21.9), (0.047-0.589) mg/L. respectively all the samples were within the limits of the standard specification for Iraqi drinking water expect the percentage of Pb was high, and absence of bacteria coliform, E.coli in all samples while a few of protozoa was noticed.
