Abstract :
Emrgence of water quality control measure has become more important as a result of water source limitation and increased discharge of pollutants arises from human activities. Besides, social and economic consequences of direct and indirect consumption of polluted waters have duplicated the importance of this control. One of the important and vital problems in healthy water is fecal contamination of water that is important to determine for controlling of epidemic of microbial intestinal disease. In order to study and determine water quality of Haraz river, this river was studied in during 2003-2004 in 17 sites from Emamzade hashem to police station of Bayjan. Water sample were analyzed for microbial (E.coli, Coli form and Total count) contamination. The results showed that the downstream have much higher E.coli and Coli form than upstream and microbiological pollutant in spring season is much higher than other seasons in all of the stations. The results showed that the average E.coli and Coli form in Haraz river water comparing with global standard, because of the various municipal, domestic, agricultural waste water and crowd… is much higher than standards for most applications and it dose not have suitable hygienic quality
