الملخص EN

The study has been conducted to Know the range of water pollution of Tigar river and some branch in Misan Governorate in heavy metal to period from 1/4 to 1/11/2011.

Nine location were chosen that Ali Al-kharbi, Kumet, Ali Al-Sharqi, Amara center, Amara near Oil factor, Majer Al-Kabeer , Kahlaa, Khalat Saleh and Azeer , one sample for each location was taken monthly.

In order to evaluate the water type the employed to measurement of EC , SAR , pH , Turbidity , Total hardness and soluble and total heavy metal ( B , Fe ,Mn , Pb and Cu).

The result showed that significant different between location in EC , SAR and pH , the high value was found in Azeer (1.6 ds m-1) and Majer Al-Kabeer (1.01) and Azeer and Khalat Saleh (8.4)for above properties respectively.

The higher value of turbidity was found in Azeer (24.000 NTU).Also in all location the value of total hardness was higher than limited properties of irrigation and drinking water.

The soluble B- concentration was higher than the limited properties in Amara near oil factor , Khalat Saleh and Azeer ( 0.696 , 0.360 .

0.433 mg l-1) .

Whereas the other soluble and total heavy metal concentration (Fe ,Mn , Pb and Cu) were less than the pollution limited in all location.
