Variations in Microbiological Water Quality of the Munzur and Pulumur River, Tunceli, Turkey at Spring and Summer Seasons

The aim of this study was to evaluate the microbial contamination of the Munzur and Pulumur River in Tunceli. For this purpose, presence of Pseudomonas aeruginosa, coliforms, faecal Escherichia coli, enterococci was investigated in four water sampling stations on Munzur and Pulumur River during spring and summer seasons. Varying levels of microbial contamination were recorded in samples from four stations. The bacteriological analyses showed that E. coli, total coliform, P. aerugionosa and enterococci reached to above 300, 200, 200 and 300 CFU/mL, respectively at summer season. However, minimum contamination level was recorded during spring season. The level of contamination in station 4 was higher than other stations, and it seems to occur mainly in summer season. Results of this study indicated that water quality has deteriorated in Munzur and Pulumur River, Tunceli.
