| Summary: | The
Sandıklı basin is located in the southwestern part of Turkey. In this paper, groundwater
stable isotope analyzes were evaluated to understand the recharge of the
aquifer system in the Sandıklı basin. For this, samples of groundwater were
collected for two periods in 2009-2010 years and the stable isotope and natural
radioactivity analyzes were made in the basin. The δ18O and δ2H
contents of groundwaters in the region range from -8.08 to -10.77‰ and
from-52.44 to -69.53‰, respectively. The stable isotope data lie generally
above the Global Meteoric Water Line and waters are meteoric origin. The
tritium content of the groundwaters ranges from 0.00 to 4.20 TU in dry period
and from 0.30 to 5.40 TU in rainy period, respectively. These δ3H
values of waters could be represented that this waters are deep aquifer waters
and slow circulation. The determination of the natural radioactivity in
groundwater is important in terms of human health. The gross alpha and gross
beta radioactivity concentrations of waters varied between 29-162 mBq L−1
and 70-330 mBq L−1, respectively. The results have shown that gross
α and ß radioactivity concentrations in drinking waters in the basin are
relatively low and suitable the World Health Organization regulations for
drinking water. |
