Evaluation of quality of drinking water produced in water treatment plants in Kirkuk and Babel governorates

Abstract

Samples drawn from four sites in Al-Hawijah district , Kirkuk governorate and Al-Mussayab district, Babel governorate during November and December 2010 .The results indicate that the filtration process in water treatment plants are inefficient due to the high levels of turbidity . The study shows significant differences at P ≤ 0.01 in the physical , chemical properties, and bacterial contamination of drinking water in the two governorates .The level of electrical conductivity , total dissolved solid , PH , and total hardness , Magnesium , exceed the acceptable levels according to the American , Iraqi and Saudi standards in the water samples drawn from (Al – Mussayab river).The level of calcium in water exceeded the acceptable standards in all samples . This indicates that Iraqi soil contains high ratio of Calcium . The microbial content shown by this study revealed clear contamination in the water which exceeds the acceptable Iraqi , Saudi and American standards level which indicate non efficient determining in these projects .
