Abstract

Physical, chemical and a biological measurments were carried out and drinking water samples were collected from four areas Abu ghraib, Dora, Ghazaliya and Saydiya for period extended from February 2016 to September 2016, through the residential sites at different areas situated with various distances from the supplying source, three samples were taken monthly. Water temperature at sampling time was varied from 17.4°C to 30.8°C, for temperature at sampling time also. The results of pH values were within the allowable limits, ranging from 6.5 in winter to 8.2 in summer. The highest value of turbidity recorded for drinking water was in spring with 21 NTU and the lowest value was in summer with 0 NTU. The study showed that the results of TDS values ware ranged from 520 mg/L in winter to 200mg/L in spring. The highest value of residual chlorine was recorded in winter with 2.01 mg/L; the lowest value was 0.1 mg/L in spring . The current results showed an increased in the number of autotrophic bacteria, total coliform, and E. coli during winter season in most study locations as compared to those of the other seasons for drinking water . The Total plat count results of drinking water were exceed 100 cell/ml, the allowable limit for drinking water, for some samples in some sites. On the other hand, the TC, and E. coli exceeded zero cell/100ml, the allowable limits for drinking water, in some drinking water samples for some sites.
