Evaluating of drinking water quality for water treatment plant in Tuz District

Abstract

This study has been conducted to evaluate the quality of drinking water for water treament plant in Tuz region,it as the only only water treatment plant in the region . Experimental tests of water parameters were: potential of hydrogen( pH),electrical conductivity,turbidity,residual chlorine,dissolved oxygen in addition to total bacteria count and total colon bacteria for raw water and treated water in the pipes transporting water in five quarters which were Raperin, Brayati ,Jumhuria ,Askry and Sada.Samples collected during the period extended over ten months started in September 2014 to June 2015. The results showed that value of potential of hydrogen were 7-8.4 which were accepted with international and Iraqi national standards.Most values of turbidity were exceed international and Iraqi national standards water quality higher value was 13.6 NTU .Values of residual chlorine were founded in each pipe that transports water to quarters but some values were little not accepted with international and Iraqi national standards water quality .In addition total bacteria count values were accepted with Iraqi standards water quality, while values of total colon bacteria values were exceed international and Iraqi national standards water quality higher value was 12.1 cell/100ml.
