Hydrogeochemical Characteristics Of The Aygır Gediği Spring, Bozkır/Konya, Southern Turkey

Abstract

The Aygr Gedii spring is located in the southern Turkey, 144 km to Konya province. In the study area, the units are of belonging to Hadim Napi and Sinatdagi Nap (Ekinlik Formation). At the top, there is Quaternary alluvium. The water source is discharged from the Lower-Middle Triassic Ekinlik Formation, which are highly fractured, cracked and karstic dolomitic limestone and sandstone and shale alternations. The spring is a typical karstic one, which is characterized by a temperature of 13 C, a flow rate of 2,2 m3/sec, a pH of 7.74-7.90 and an electrical conductivity of 155-467 mho/cm. Feeding and discharge periods of the source range from January to April, and April to October, respectively. The flow rates are between 2-5 m3/sec and 0,063-0,095 m3/sec during the feeding period and discharge period, respectively. The dominant ions in the spring water are calcium, magnesium and bicarbonate, and can be classified as calcium, magnesium, sodium, chlorinated water based on the AIH classification (Association of International Hydrogeology). According to the Schoeller diagram, water in the study area is of the same origin and the order of ions is rMg> rCa> rNa> K, rHCO3> rCl> rSO4.
