Abstract
Groundwater in Pakistan is the main drinking water source, highlighting the significance of regularlymonitoring its quality. There have been several examples of high concentrations of elements like arsenic and nitrate ingroundwater that harm human health and the environment. Our aim with this study was to assess the groundwater qualityof the sub-district Bhulri Shah Karim for drinking and irrigation purposes. We collected groundwater samples from 53shallow bore well hand pumps in October and November 2018. We determined the concentration of four cations, fiveanions and other parameters like pH, turbidity, TDS, total hardness, EC, alkalinity, total iron, and arsenic. Thegroundwater was found to be very hard, and the relative abundance of cations and anions was Na+> Ca2+> Mg2+> K+ andCl‾ > HCO3‾ > SO42‾ > NO3‾ > F‾. The concentrations of arsenic and iron varied from 0 to 0.2 mg/L and 0.02 to 3.6mg/L, respectively. We discussed groundwater quality for drinking and irrigation purposes by calculating the waterquality index, sodium adsorption ratio, percent of sodium, permeability index, and residual sodium carbonate. Inconclusion, the groundwater of the studied area is suitable for drinking on average and irrigation. However, some watersamples were high in arsenic content, and some were highly saline and may need some prior treatment
