Abstract Groundwater pollution poses significant health and environmental risks, particularly in regions heavily reliant on this resource. This study assessed nutrient manganese groundwater of the northeastern Nile Delta, identifying sources evaluating associated risks. An integrated methodology was employed, incorporating water indices, risk modeling, satellite imagery analysis, statistical analysis. Thirty-one samples were analyzed for nitrate, nitrite, ammonia, phosphate, manganese. Concentrations ranged from 0.3 to 52 mg/L, 0.2 11.3 0.02 25 0.1 2.3 0.01 1.94 respectively.
