Bathymetric, Physicochemical and Microbiological Analyses of Sarikum Lake (Sinop-Turkey)

Abstract

Sarikum Lake located in the protected area of Sarikum Village boundaries of Sinop Province Central District was investigated in terms of bathymetric, physicochemical and microbiological aspects. This study was carried out between October 2017 and March 2018. For bathymetric analysis, a Garmin echo 551 c brand dual frequency depth gauge (echo sounder) and 2 GPS receivers were used. For pollution parameters, water samples were taken from stations determined at 3 different points of the lake. Parameters such as temperature, Total Dissolved Solids (TDS), salinity, electrical conductivity, Oxidation Reduction Potential (ORP) and pH were measured with the multifunctional meter during sampling. In addition, ammonia nitrogen (NH₄⁺-N), iron (Fe), phosphate phosphorus (PO₄^3--P), manganese (Mn), nitrite nitrogen (NO₂^--N), nitrate nitrogen (NO₃^- -N) and total hardness (Ethylene Diamine Tetra (EDTA) titrimetric) according to standard methods (Apha, Awwa, Wef, 2005). Total coliform, E. coli, fecal streptococcus, fecal coliform, sulfide reducing anearob and Clostridium perfringes analyzes were performed for microbiological analyses. Sulfide reducing anaerobes were not detected in the assay results. Based on the obtained results, it is determined that Sarikum Lake within the sanctuary area of Sarikum Village of Sinop province (Turkey) is close to the dirty / pollution limit according to the inland field regulations.
