Sinop ili içme ve kullanma suyu ihtiyacı, Karasu Çayı üzerindeki Erfelek Baraj Gölü’nden temin edilen suların Sinop Belediyesi içme suyu arıtma tesisinde arıtılması ile karşılanmaktadır. Bu çalışmanın amacı su sıcaklığı, hidrojen iyonu konsantrasyonu, çözünmüş oksijen konsantrasyonu, elektriksel iletkenlik, bulanıklık, toplam demir ve mangan iyonu olmak üzere yedi göstergenin referans alınarak baraj gölü su kalitesinin değerlendirilmesidir. Ayrıca, içme amaçlı kullanılan sular için arıtma sonrası su kalitesi amonyum azotu, nitrit azotu, nitrat azotu, klor, bakiye klor ve bakır iyonu olmak üzere altı göstergeye göre daha değerlendirilmiştir. Her biri bir yıl olmak üzere iki dönem için günlük su kalitesi verileri incelenmiştir. Kalite değerlendirmesi Yerüstü Su Kalitesi Yönetmeliği’ne (YSKY) göre yapılmıştır. Arıtılmamış rezervuar suları için sonuçlar, YSKY tarafından izin verilen seviyelere uygun bulunmuştur. Diğer yandan, arıtma sonrası su kalitesi, İnsani Tüketim Amaçlı Sular Hakkında Yönetmelik’e uygun bulunmuştur. Erfelek Baraj Gölü için 2014 ve 2023 yılları su kalitesi indeks değerleri de hesaplanmış ve su kalitesinin zamana bağlı değişimi incelenmiştir. Erfelek Baraj Gölü su kalitesinde, özellikle de 2023 yılının yaz aylarında, 2014 yılına kıyasla önemli bir bozulma olduğu sonucuna varılmıştır. Sinop ilinin içme suyu kalitesi ilk kez bu çalışma ile değerlendirilmiştir.

Water Quality Assessment of the Erfelek Dam Lake in the Context of Drinking Water Treatment Plant, Sinop Municipality, Northern Türkiye

Öz

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.
