Quality of drinking water in El-Tall-El-Kabier region Ismailia, Egypt

ABSTRACT

Water samples collected from 28 water sources used for human consumption representing 24 producing wells, and 4 Nile- Water taps distributed in the villages streets, were bacteriologically and chemically studied. These drinking water sources in El-Tall El-Kabier region were evaluated and examined for safe potability. Data obtained revealed that water front wells of the depth 1.5 to 14 meters have a bacterial load that is potentially pathogenic regarding their coliform counts [2.2 x 104 cfu/100 mL]. Water samples from wells of the depth 16 meters and more; up to 39 meters, were found bacteriologically safe, having zero counts of faecal coliforms /100 mL, and not more than 3 cfu/100 mL coliforms, but with a high content of residual sulphates, chlorides, carbonates, and unsafe salinity levels. Sulfates 591.1 mg/L chlorides 934.6 mg/L, carbonate 740 mg/L, salinity levels 1792%. According to the health aspects, these contaminate are considered hazardous, and the water having them is unsafe for drinking, as recauneaded in the international standards
