Assessment of Metal Concentrations and Physicochemical Parameters in the Water of Beyler Reservoir (Kastamonu, Turkey)

The Physico-chemical parameters (Water temperature, pH, dissolved oxygen (DO), total hardness, calcium (Ca), magnesium (Mg), nitrate (NO3-), nitrite (NO3-), phospate (PO43-)), and some metal concentrations (Fe, Zn, Cu, Mn, B, Cr, Ni, Pb, and Al) were measured in the water samples to determine the water quality of the Beyler Reservoir. This reservoir is used for irrigation in the Kastamonu Region in the North Central Region of Turkey. The study was conducted seasonally in 2009-2010. The distribution of Zn, Mn, Cr, and Ni metals between stations was statistically significant (p<0.05, p<0.01) while the only metal displaying significant differences between seasons was Cr (p<0.05). When the water quality classes were examined in terms of the measured metals and physico-chemical parameters, it was detected that the reservoir has a considerably high quality water and can be used as potable water in terms of these parameters.
