Determination of bacteriological pollution level of Gelevera Creek (Giresun)

The aim of present study is to investigate the bacteriological water quality and pollution level in Gelevera Creek, Giresun. For this purpose, a total of 48 water samples were analyzed between April 2017 and March 2018 from 4 different stations for bacteriological parameters using the standard methods. Bacteriological: water and sediment samples: 37°C total viable bacteria count, surface water samples: total coliform bacteria (TC), fecal coliform bacteria (FK), fecal streptococci (FK), and E. coli analysis were done. The presence of TC, FC and FS of surface water samples were 100%, 100% and 93,75%, respectively. Also, E. coli has been identified throughout the study of all seasons The total coliform, fecal coliform and fecal streptococci levels are exceeding exceed the values specified the WHO guidelines and the Turkish standards. This situation is likely to cause serious and irreparable damage to the streamline. As a result, it has been determined that surface water samples from Gelevera Creek are bacteriological polluted. Therefore, the present study suggests regular monitoring and assessment for reducing the bacterial load into the Gelevera Creek Basin through appropriate measures.
