Background and Objective: Jordan's drinking water scarcity is desperately needed and it plays a critical role in improving safe drinking water quality, which is critical for nutritious and clean drinking water quality, which is a vital component of good public health. Recognize the potential risk of repeated exposure to high nitrate concentrations in drinking water in the A Duliel area and measure the impact on local communities' human health. Materials and Methods: In 2016, samples of groundwater were taken. With a mean value of 44.4 mg L^–1, nitrate concentrations ranged from 10-81.0 mg L^–1. Results: The findings showed that human activities, especially the extensive use of chemical fertilizers in agriculture, could be attributed to high NO₃ concentrations. To assess the possible risk to human health, Chronic Daily Intake (CDI) and Hazard Quotient (HQ) has been assessed. In the classes considered, infants tended to be at a greater risk than children and adults. Furthermore, the findings showed that in most of the groundwater considered, the health of people from nitrate contamination was not adequate and was also at risk from known concentrations of nitrate. Conclusion: Appropriate steps to improve groundwater protection and to better track and control stable sources of nitrate emissions are also important.
