YERALTISUYU TUZLULUK VE KİRLİLİK ÇALIŞMASINDA ÖZDİRENÇ YÖNTEMİ VE GÜZELÇAMLI(AYDIN-KUŞADASI) UYGULAMA ALANI

distribution of ground water were enlarged leading to a comprehensive study including salinity and pollution. The resistivity studies were conducted at 14 points by using vertical electric drillings, the Schlumberger series. The average depth of vertical electric drillings were selected as 250 m. With the help of this study, an alluvial formation affected by the saline water was observed at depths that are close to surface (nearly 10-30 metres). This situation indicates an important salinity problem. Water samples were taken from 72 boreholes in order to investigate the size of actual salinity and pollution. When all the borehole data are investigated together (in chemical and bacteriological manner), it was determined that merely 22 % of the boreholes could be utilized. Under the guidance of this study which was forwarded to a region extending between Ayd-n-Ku/adas--Güzelçaml-, an important ground water problem is in question within the study area. The water pollution problem should be disposed by taking necessary measures such as purification and distilling

RESISTIVITY METHOD IN GROUNDWATER POLLUTION AND SALINITY STUDY AND GUZELCAMLI (AYDIN-KUADASI) APPLICATION AREA

In this investigation, the results derived from the resistivity study in order to monitor the distribution of ground water were enlarged leading to a comprehensive study including salinity and pollution. The resistivity studies were conducted at 14 points by using vertical electric drillings, the Schlumberger series. The average depth of vertical electric drillings were selected as 250 m. With the help of this study, an alluvial formation affected by the saline water was observed at depths that are close to surface (nearly 10-30 metres). This situation indicates an important salinity problem. Water samples were taken from 72 boreholes in order to investigate the size of actual salinity and pollution. When all the borehole data are investigated together (in chemical and bacteriological manner), it was determined that merely 22 % of the boreholes could be utilized. Under the guidance of this study which was forwarded to a region extending between Ayd-n-Ku/adas--Güzelçaml-, an important ground water problem is in question within the study area. The water pollution problem should be disposed by taking necessary measures such as purification and distilling.
