Abstract

The purpose of this study was to determine distribution of fecal indicator bacteria (FIB) including Total coliform (TC), Escherichia coli (EC) and Fecal streptococcus (FC) and Clostridium perfiringens (CP) in rural water supplies (ground, spring, surface) in the city of Ordu, its surroundings and boroughs (Unye, Ulubey, Fatsa, Kabatas, Korgan, Persembe, Golkoy, Akkus, Kumru, Gulyali, Gurgentepe, Catalpinar) and in rural drinking water which is not any water treatment (Ordu's village, Fatsa, Catalpinar, Kumru, Ikizce) Middle Black Sea, Turkey. 1020 rural water samples were collected on a weekly basis from up to 13 discrete sampling sites in Ordu and boroughs between September and february in 2010-2011.
