Contamination rate of surface waters in ilam province with pathogenic speacum of Enterococci

Background and Aim : Water is a vital fluid that is contaminated by a variety of biological factors.Enterococcus species are the most important indicator of surface water pollution.surface water can be contaminated with enterococcus species and transmitted to other area.therefore,in this study,the frequency of bacterial contamination of surface waters of ilam province with enterococcus species was measured.Methods : In this study, sampling from ۲۳ ILAM surface pollen stations and their biochemical tests showed the infection rate of different Enterococcus bacteria in winter and summer and compared their prediction and infection.Results : The population of Enterococci at different stations in summer and winter is different so that the population of Enterococci in Mehran saffron station in summer and in Chenguleh station in winter are the most polluted.Conclusion : The more suitable the temperature and the higher the discharge of municipal wastewater into the river water has been the cause of increased pollution. In addition, the lower the precipitation in these seasons, and the higher the pollution load.
