Themicrobial quality which included Aerobic plate count (APC), total coliform, staphylococcus aureus, presumptive test for Salmonella and mold and yeast in addition to some physiochemical quality such as PH , BOD , TSS , Calicum and sulfate ion for marshes water taken from four areas in Thi-Qar governorate ware studied.

The results showed that the APC the and total coliform count ranged from 2.5×105 to 158 × 105 CFU/ml for APC and from 32 × 102 to 72× 102 CFU/ml for total coliform and from 90 to 700 CFU/ml for staphyloccus aureus, while the count for mold and yeast ranged from zero to 20 CFU/ml .

the highest counts for APC and Coliform were in region (B) which were 185×105 and 72×105 CFU/ml respectively.

80% of the all water samples did not contain salmonella .

the highest count was for staphylococcus aureus is region (D) which was 700 CFU / ml .

the results for physiochemical studies showed the PH value ranged between 7.6 to 7.9 while BOD was between 4.1 to 4.4 mg/liter.the highest value for TSS , calcium and sulfate ions of water samples during the study period were 115.3 , 10.2 and 598 mg/liter respectively.
