Abstract
To determine the geochemical processes impacting groundwater geochemistry and its appropriateness for drinking and irrigational uses, a thorough examination of groundwater is conducted in some areas of the Afzalpur taluk. According to the results of a thorough chemical analysis, the research area's groundwater has a pH average between 6.7 and 6.3, making it fairly acidic. Mg2+ and Ca2+ cations and HCO3- anions are also present in high amounts. Ion-exchange and rock weathering mechanisms were perceived to dominate the groundwater chemistry, with anthropogenic sources playing a minor role. Particularly, the electrical conductivity, total hardness (TH), and concentrations of Na+ and HCO3- exceeded the BIS and WHO water quality standards' acceptable limits. Groundwater suitability for irrigation was assessed on the basis of sodium adsorption ratio, Na%, magnesium hazard (MH), residual sodium carbonate (RSC), and Kelley's index (KI). Above parameters revealed that nearly 40 to 50 % of the groundwater in the sampling sites was of high-quality for irrigation purpose.
