This study comprehensively assessed the groundwater quality for drinking and irrigation, its hydrochemical characteristics, and potential health risks associated with nitrate (NO3) concentration via the oral pathway. The studied parameters were within the acceptable limits, except for TDS, turbidity, Na, K, SO4, and Cl, which exceeded the limits in 11%, 27%, 21%, 100%, 66%, and 7% of groundwater samples, respectively. Based on the water quality index (WQI), 54% of the samples were classified as good, while 42% were categorized as poor for drinking. A small percentage (2%) of each was deemed very poor or unsuitable, indicating a health risk. The sodium adsorption ratio (SAR) analysis revealed that 68% of samples were excellent for irrigation, whereas 45% and 25% were doubtful or unsuitable based on the sodium percentage (Na%). The Piper plot analysis revealed Na/K-Cl/SO4 and Na/K-HCO3 as the dominant geochemical facies. The chemical composition of groundwater was primarily influenced by natural processes such as rock-water interactions, ion exchange, and human activities. Both deterministic and probabilistic assessments suggested minimal health risks for adults and children. Sensitivity analysis highlighted the significant impact of NO3 concentration on health risks, with exposure frequency, body weight, and concentration emerging as the key influencing factors. Correlation analysis revealed that natural and anthropogenic activities were major contributors to contamination. Continuous monitoring of groundwater quality and implementing remedial actions to address contamination risks in the region are recommended.
