Figure 1. Isparta Stream and sampling points northern side of Akdag Mountain, Yukari Direkli village (1200 m. alt.) which has no waste water connection. By the border of Asagi Direkli village, waste water from Isparta town is discharged to Isparta stream. 2nd sampling point is located at the end of Direkli stream. The 3rd sampling point is on the main road between Antalya and Isparta, 4th sampling point is near Dariéren village. Sth sampling point is on Dartéren stream that joins to Isparta stream, 6th sampling point is in Derebogazi area by Isparta-Antalya main road (Figure 1).
