Abstract
Total aerobic bacteria, total coliforms, faecal coliforms and faecal streptococci were monitored in water samplescollected from twelve stations located in two water sources in Baghdad city. The samples were collected at a monthly intervals during the period December 1980 ‐December1981.
High counts of pollution indicator bacteria were observed at all the stations studied. All of these bacteria were found to be distributed independently of temperature, PH., and chloride concentration of the water samples.
