Evaluate the bacteriological characteristics of certain water treatment facilities in Kirkuk city

The present study aims to evaluation the bacteriological characteristics of several water treatment plants in Kirkuk City. Four plant water treatments were chosen in different regions of Kirkuk City. The water samples were attained from the distributed network. 1L of water samples was collected monthly (6 months) from August 2020 until January 2021. The results showed that the total Coliform and faecal coli form values ranged between 0-51 X103 cell/100ml in Al-Kadhimiya, Al Shajarah, AL Basal and Abu al-Jess, where the highest value was recorded in October for Al-Kadhimiya, while the lowest value in August for Al Shajarah.  The faecal Streptococcus values ranged between 0-25 X103 cell/100ml in Al-Kadhimiya, Al Shajarah, AL Basal and Abu al-Jess, where the highest value was recorded in August for AL Basal, while the lowest value in January for Al- Kadhimiya. It concluded that the bacteria parameters exceeded the international and Iraqi national standards and limits of water quality. These parameters include several total Coliform, faecal coli form and faecal Streptococcus. It concluded that the water in some areas of Kirkuk suffers from high bacterial pollution, which makes the water unfit for drinking, and that there is pollution with sewage water and raw water.
