Physicochemical and chemical quality of mailsi city groundwater

Abstract

Quality of groundwater samples in Mailsi city of district Vehari was assessed using physico-chemical and chemical parameters. Twenty seven (27) groundwater samples were collected for physico-chemical and major ion analysis. Absence of carbonate ions (CO 3-2) in all groundwater samples indicates presence of limestone dissolution giving rise to bicarbonate. Piper diagram reveals dominance with Ca-Mg-type of water in the studied area. pH of all samples were within WHO guidelines. The mean value of Total Dissolved Solids (TDS) for Mailsi groundwater is 755.1 mg/L having a range of 272 to 1667mg/L. The TDS for majority of samples lies above the guideline values as defined by the WHO. Twenty two (22) percent samples exhibit high nitrate levels; consumption of water samples with high nitrate content may produce harmful effects in children.
