Seyfe Gölü Çevresinin (Kırşehir) Yeraltı Suyu Kalitesinin Coğrafi Bilgi Sistemleri (CBS) Kullanılarak Belirlenmesi

Abstract

Groundwater is widely used for both potable water and agricultural purposes in Turkey. In this study, groundwater quality and the factors of contamination with their impact areas has been assessed using geographical information systems and geostatistical techniques at Seyfe Lake, east of Kırşehir province. For this purpose, the samples from groundwater has been chemically analyzed depending on TS 266-2005 and WHO-2006 standards and contamination maps has been prepared using Inverse Distance Weighting (IDW) interpolation techniques. It has been thought that the contaminations at the study area is related with lithology and NO3, SO4, As, F and U increase depending on unconscious use of fertilizers and pesticides in agriculture. The groundwater that can be used as potable water has been determined around Bozçaldağ formation (marble). Therefore, it has been foreseen that Bozçaldağ formation areas can primarily be preferred for groundwater that will be used as potable water.
