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
