Introduction: Underground river or streams are one of the groundwater resources that are used for many important purposes with the largest amounts to irrigation of crops as well as local public use such as for delivery household, business sector and industrial area. Groundwater resources, is of vital importance for human activities as mentioned above for various human consumption, thus it become important by sanitation point of view.
Material and Methods: This study was carried out in a groundwater stream which is situated in the Mount Kazdağı. For this purpose, water samplings were performed in bimonthly periods, from three different stations pre-selected localities in the groundwater. Water samples were transported in cold chain (+4C°) by using thermos boxes. In the laboratory, water samples were inoculated to the selected medium immediately after transportation. Total coliform bacteria, Escherichia coli and fecal Streptococcus procedures were applied.
Results: In this periodical study, we were detected higher levels of the bacteriological contamination: total coliform bacteria, Escherichia coli and fecal Streptococcus, in only September 2016 that decreased the water quality class.
Discussion: Flow regime of the underground stream was very fast in the season winter and spring considered as wet season which is not detected any bacteriological contamination. Once the flow rate reduced at the season autumn, risky bacteriological contamination was detected especially in fecal Streptococcus indicating animal activities such as bats nesting in the karst system.
