Özet
Objective: Lake Van is one of the most important recreation areas of the region. Investigation of microbiological pollution of Lake Van is very important for public health. The aim of this study is to assess the microbiological pollution and determine water quality of the lakes Van and Erçek situated within Van Province, which are used for swimming and recreation to protect both human and environmental health. For this purpose, the presence of fecal coliform, total coliform and enterococci were investigated in samples taken from 29 different points of the lakes. Method: Between June and September 2015, 232 water samples were taken from predefined 29 points, every two weeks, and sent to the Public Health Laboratory of Van Province in 300-500 mL sterile plastic bottles in accordance with Bathing Water Quality Regulation (76/160 / EU: add-on clause 5. Membrane filtration method was used to analyze the samples for coliform bacilli and enterococci. Mandatory values according to bathing water quality regulation were taken as 2000 cfu/100 ml,10000 cfu/100 ml and 1000 cfu/100 ml for fecal coliform, total coliform and enterococcus, respectively. Results: In 196 (84%) of 232 water samples collected, no bacterial contamination was found, while 36 (16%) samples were found contaminated with fecal coliform, total coliform and Enterococcus species. At least one or more specimens of poor quality water were detected in 17 of 29 sampled beaches. Conclusion: It was envisaged to take precautions by restricting the use of the places where microbiological pollution was detected. In addition, regular analyzes are important for public health.
