Abstract :

            In this survey, in order to study the Coliform pollution of Shafarud River, two layers from surface and sediment were sampled in five stations. Sampling was done seasonally during a year. The pollution by standard diagnosis of Coliform was completely examined. The most pollution was found in sediment layer of delta area. Besides, the highest Coliform count was seen during summer amounting to (44.2) Coliform in 100 cm3 and Fecal Coliform (22.1) in 100 cm3 river water. In summer, due to the high temperature, growth of bacteria is more than ever and in the delta area, because of calm flowing of water and it is passing through the city and agricultural centers, and entering garbage into it, the amount of pollution has been apparently reached a high level in comparison with other parts of the rivers with rapid flowing of water.
