Hydrogeological Investigation of the North of Kaman (Kırşehir) Region

The present study conducted in north of Kaman (Kırşehir) regions of Turkey, which has rocks with different origin, recently abandoned iron and fluorite mines and agricultural activity. The units indicating aquifer characteristics in the study area are Buzlukdağ Synite and Kızılırmak Formation consist of sandstone, conglomerate,tuff, limestone and mudstone. As, F, U concentrations of many spring (KMK-9, KMK-17) discharging from syenites, As, NH4 concentrations of many spring (KMK-3, KMK-5, KMK-6, KMK-7, KMK-8) discharging from clastics, As concentrations of many springs (KMK-18, KMK-19) discharging from synites and metamorphic rocks, and U, NH4 concentrations of one water (KMK-2) discharging as a fountain consisting of a combination of a well that was opened in the clastics and discharging from syenites as a spring the study area exceed the limits of Ministry of Health-2005 Standard. In addition, NO3 and NH4 concentrations in many wells (KMK-4, KMK-10) (clastics), U concentrations in manys prings (KMK-14 (syenites), KMK-16 (contact of syenites-metamorphic) and F concentration in one spring (KMK-15 (syenites)) exceed the limit values. The results of field measurements and analytic experiments showed that the weathering of rocks, dissolutioun from mines (iron and floride) and rocks and/or mining and agricultural activities in the study area strongly influenced the physicochemical processes in the waters. These pollutants in water can pose a great risk to humans, animals and plants.
