Water Quality Assessment of the Erfelek Dam Lake in the Context of Drinking Water Treatment Plant, Sinop Municipality, Northern Türkiye
Abstract
Domestic water demand for the city of Sinop has been supplied by the Erfelek Dam Lake on the Karasu Stream after treatment at the drinking water treatment plant of the Sinop Municipality, Türkiye. The aim of this study is to assess the dam lake water quality firstly with reference to seven parameters: water temperature, hydrogen ion concentration, dissolved oxygen concentration, electrical conductivity, turbidity, total iron, and manganese ion. It is to assess the suitability for human consumption lastly with reference to six more indicators: ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, chlorine, residual chlorine, and copper ion. Daily water quality data was considered for two periods, each of which is one year. The quality assessment was performed according to the Turkish Surface Water Quality Regulation (TSWQR). The results for the untreated reservoir waters matched the permissible levels by the TSWQR. On the other hand, the after treatment water quality and safety of the reservoir waters matched the standards imposed by the Regulation Concerning Water Intended for Human Consumption. In addition, water quality index (WQI) values for the years 2014 and 2023 were calculated for the Erfelek Dam Lake, and the temporal change of the water quality was investigated. Calculated WQI values indicated a significant deterioration in the water quality of the Erfelek Dam Lake in 2023, particularly in the summer months, compared to 2014. With this study, the drinking water quality of Sinop Province is assessed for the first time.
