This investigation was conducted to study chemical and biological properties
(Al , Zn, NO3, K, , Ag , Cr and Cd ppm C% , PH , Salt g/l and the biological properties such as COD and BOD) ppm of water 8 water well during winter and summer seasons , 2012 at Al- Taji North of Baghdad City –Iraq.
The result indicated that the Chemical and biological properties of water at 8 water wells values of July , 2012 were higher ( more polluted ) than the values of January 2012. The salt had a significant different relation at 0.05 level with PH ( r = -0.655 ) , C% ( r = 0.649 ), Al( r = 0.592 ) , COD( r = 0.721 ) and BOD( r = 0.728 ) between the above properties in January,and July well water of 2012.
It was noted that the surrounding environment and climate affected water quality.
