Summary of water quality indices in present study [10], [11], [12], [13], [14].

Indices	Formula
Sodium percentage (Na %)	$\mathrm{Na}\%=\frac{\mathrm{Na}+\mathrm{K}}{\mathrm{Ca}+\mathrm{Mg}+\mathrm{Na}+\mathrm{K}}\times 100$
Sodium adsorption ratio (SAR)	$\mathrm{SAR}=\frac{\mathrm{Na}}{\sqrt{(\mathrm{Ca}+\mathrm{Mg})/2}}\times 100$
