The Levels of Bio-Indicator Bacteria in the Fresh Water Resources of Eastern Anatolia Region of Turkey

Abstract

In this study, anthropogenic influences on the natural fresh water sources regarding the levels of indicator bacteria were investigated in the Eastern Anatolian, Turkey. The surface water samples (0–30 cm) were collected seasonally in the period between November 2008 and October 2009. The levels of total and faecal coliform bacteria were tested using membrane filtration technique. The detected coliform bacteria in the sampling region, where livestock raising activities are intense, revealed the region under the influences of bacteriological pollution inputs. The results also showed that freshwater sources of the region carry a potential risk for human health. This is the first data that can be used in the assessment of bacterial risks of these water sources in the Tunceli and Munzur Valley of the Eastern Anatolia, Turkey. Bacteriological monitoring studies are needed to be established for detecting of pollution sources and sustainable use of natural water resources.
