Comparative study about the safety of drinking water supplies in Baghdad City

حول في

The monthly and seasonal averages of physiochemical and microbial properties of 336 drinking water samples collected from 14 sections in Baghdad city include (Al-Kadimiya, Al-Kadraa, Al-Ameriya, Al-Bayaa, Al-Saydiya, Al-Qadisiya, Al-Doora, Al-Qahera, Al-Aadamiya, Madenat Al-Sader, Al-Baladiyat, Baghdad Al-Jadeeda, Al-Karada and Al-Zaafaraniya) for 12 months were studied. The studied properties include the averages and concentrations of turbidity, pH, electrical conductivity, total dissolved solids, total hardness, calcium, magnesium, chloride, lead, aerobic bacterial total count, total and fecal coliform, fecal streptococci, Pseudomonas aeruginosa, and detection of Salmonella. The results clarified the failing of 25% samples in the application of the sanitary demands stated in the confirmed Iraqi standards that essentially referred to aerobic bacterial total count, and the failing of 33.42% samples in the application of physiochemical demands which essentially referred to lead concentrations. The samples from Al-Zaafaraniya station recorded the highest averages of the studied properties; while the samples from Al-Kadraa, Al-Bayaa, Al-Saydiya recorded the lowest averages. This study discussed the effects of seasons and maintenance measures on the studied properties. The correlations among the physiochemical and microbial properties.
