Values are a mean ± standard error (n = 9). Values labeled with letters show significant differences between two seasons in the same site. The same letters show no significant difference (p ≤ 0.05). Values with “#” depict higher and significant difference between two sites in the same season. Abbreviations: EC_e- electrical conductivity; TOC-total organic carbon; SP- saturation percent
