AbstractABSTRACT - Water samples were collected from four sites with three stations at each site from some of the Iraqi marshes (Hor Al-Hammar, Abu-Zarek, Al-Eaz and Hor Auoda). Samples were analyzed for pH, dissolved oxygen, BOD, COD, TSS, nitrate, chlorides, iron, manganese, calcium, magnesium and sodium. Water quality was classified according to Prat′s classification, and distribution coefficient (Kd) for transportation of pollutants between the liquid phase and the solid phase was used. The results indicated that pH and BOD values of water were ranging from excellent to acceptable; dissolved oxygen was excellent; Salinity and T.S.S was excellent and a good indicator for polluted waters; Nitrate was excellent to acceptable; Fe and Mn were acceptable to excellent. Results of Kd values showed that sediment had high concentration of iron and manganese than water which could provide water with iron and manganese.
