Water Quality in Tortum Stream and its Tributaries (Erzurum/Turkey)

Bu çalışma, Tortum Çayı ve Kollarına evsel atıkların ve hidroelektrik santral inşaatının su kalitesine etkisini belirlemek amacıyla yapılmıştır. Tortum Çayı ve Kollarında belirlenen 9 istasyonda Haziran 2012- Mayıs 2013 tarihleri arasında aylık su örnekleri alınmıştır. Bu örneklerde toplam fosfor, ortafosfat, toplam demir ve silikat değerlerine ek olarak sıcaklık, pH, çözünmüş oksijen, Ca-sertliği, toplam sertlik, alkalinite, askıda katı madde, sülfat, amonyak-azotu, nitrit-azotu, nitrat-azotu değerleri analiz edilmiştir. Tortum Çayı ve kollarının fiziksel ve kimyasal özellikleri, Su Çerçeve Direktifi ve Su Kirliliği Yönetmeliği Kıta İçi Su Kalite Standartlarına göre incelendiğinde su sıcaklığı, çözünmüş oksijen ve sülfat değerleri hariç düşük kaliteli su standartlarında olduğu söylenebilir. Sonuç olarak Tortum Çayı ve Kollarından gelen evsel atık, hayvansal orjinli gübre ve hidroelektrik santrallerinin inşaat atıkları sebebiyle kirlilik tehdidi altındadır

Tortum Çayı ve Kollarının (Erzurum/Türkiye) Su Kalitesi

This study was undertaken with the aim of determining the effects of domestic waste and hydroelectric dams on water quality in the Tortum Stream and its tributaries. Water samples were taken monthly from nine sampling points of Tortum Stream and its tributaries between July 2012 and May 2013. Analyzed for temperature (°C), pH, dissolved oxygen (DO), total suspended solids (TSS), alkalinity, Ca, total hardness, sulfate (SO4), ammonia-nitrogen (N-NH3−), nitrite-nitrogen (N-NO2−) and nitrate nitrogen (N-NO3−) as well as total phosphorus (TP), total orthophosphate (TO), total iron and silica (SiO2) were carried out. Physical and chemical characteristics of Tortum Stream and its tributaries which were examined according to the Water Framework Directive and the Water Pollution Control Regulations. It can be said that the stream has a low water quality standard except for water temperature, dissolved oxygen and sulfate. The results showed that Tortum Stream and tributaries are under threat because of domestic waste, fertilizers and hydroelectric constructions
