The South Baghdad electrical station located on the eastern bank of the Tigris River south of Baghdad city was selected within the municipality of Karrada between two latitude ( 330 15 , 33 0 18 )North and longitude ( 44 0 27 , 44 030 ) East .

The purpose of the study is to determine the contribution of the station to the effect of pollution of the Tigris water by taking water samples at the station site and two sites, one before and the other after the station, distributed over time periods of three months between each sample of water and the beginning of August and November Shabat and Mayar and analyzed water samples physically, chemically and biologically, It was found that the highest percentage of pollution was at the site of the station and the highest percentage of pollution was in August and reached (52.94) % as the contaminants that crossed the border were allthat turbidity and electrical conductivity and temperature and Chemical Oxygen Demandand Total Suspended Solids and Phenols and Biological Oxygen Deman and Total Plate Count and Fecal Coliform Bacteria, And then it was in November (47.05) % and represented by eachturbidity, electrical conductivity and Chemical Oxygen Demandand Total Suspended Solids and Phenols and Biological Oxygen Deman and Total Plate Count and Fecal Coliform Bacteria , The same percentage was in May (47.05) % turbidity and temperature and Chemical Oxygen Demandand Total Suspended Solids and Phenols and Biological Oxygen Deman and Total Plate Count and Fecal Coliform Bacteria, While the lowest percentage of pollution was in February (23.54) %.

Including both turbidity and Phenols andTotal Plate Count and Fecal Coliform Bacteria, And the percentage of pollution in the site after the station is greater than before.

The difference coefficient was obtained.

The most variant wasphenols (90.0 ) % and lower it withTotal Hardnessreached ( 6.36 ) % .

As for the relationship of the correlation of the pollutants with the temperature, it was the highest value of positive correlation withWhere the highest correlation value was withTotal Suspended Solidsreached ( 0.96 ) and lower it withSulfatereached (0.06 ) the negative correlations with the temperature were negativeturbidity , PH, Nitrate, Alkalinity, Total Hardness .
