Microbiological Analysis on Tigris River Water in the Selected

Bacteriological analyses were carried out on Tigris River water while passing through Baghdad City the capital of Iraq. The Tigris River was selected in this study because this river supplies water for many sector of development like agriculture, industry, transportation, aquaculture, public water supply. Microbial pollution indicators such as- total count, total coliforms, fecal coliforms was studied, Samples were collected over a period of twelve months from September 2013 to August 2014. The results showed variation in the number and density of microbial indicators between month and seasons of study sites. A highest number of bacterial pollutants recorded through summer and spring seasons. The total coliform and Faecal coliform counts exceeding acceptable limits are indicative of pollution. to protect human health must reduce the pollution of the river through control the levels of pollutants discharged into Tigris River and reduce dissemination of the coliform and fecal coliform bacteria
