Hydrochemical Analysis and Evaluation of Groundwater Quality and Agriculture Soil of Khairpur Taluka, Sindh, Pakistan
Abstract
The inhabitants of Khairpur Taluka mostly consume groundwater for drinking and agriculture purposes. The present study was conducted to monitor the essential quality parameters of groundwater and soil. Both groundwater and soil samples of the area were classified as alkaline. All the major ions except Na and SO4 were found within the permissible limits, while the concentrations of Zn, Fe, Co, Pb, Ni and Mn in studied groundwater samples were found above the specified limit of WHO. However, soil samples were found rich in major and trace elements except Cd, which was low in comparison to world average of agriculture soil. Irrigation character of water samples on Sodium Adsorption Ratio (SAR) vs. Na% plot display fair type with few exceptions. The piper diagram implied mixed water composition with Na-Ca-Mg and HCO3SO4+Cl as dominate ions. Diverse shapes of Stiff polygons also support the mixed nature of groundwater in the study area.
