Abstract

Seventy samples were collected out from water supplies of seven stations at Basrah governorate from October, 2015 to April, 2016 to estimate physical characteristics and fecal coliform bacteria content. The fecal Coliform bacteria ranged from 1–1370CFU/100 mL belonging to the species E. coli, Citrobacter sp and Enterbacter sp., The water temperature range (9 - 30 ) °C , turbidity ( 1.12 - 215.0) NTU, pH (7.0-8.8), electrical conductivity (0.24-9.48) ms/cm, salinity (0.15-6,07) g/L (PSU) and residual chlorine (0.01-3.56) mg/L. The results have shown contamination of water supplies with pathogenic microscopic organisms such as bacteria and pathogenic viruses. Furthermore, physical and chemical characteristics of water investigations have indicated the excess of the average values of some characteristics in most places subjected to the present study above the permitted WHO and Iraqi standards of drinking water.
