This work aims to evaluate the pollution hazards of surface and groundwater at El–Sadat City, Egypt. Forty-five water samples were collected from the surface water bodies (El–Nasery canal and the oxidation ponds) and groundwater samples at the study area. The chemical composition of the water resources at El-Sadat city was outlined through out determination of pH, EC, TDS, major cations and anions. The pollution of the collected water samples was evaluated based on determination of minor elements, trace and soluble heavy metals as well as biological and bacteriological pollutants
Results revealed that all surface water samples (El–Nasery canal) and the majority of the groundwater samples (93%) in the study area are fresh water, while the rest of the groundwater samples (7%) are brackish water. All surface water and majority of the groundwater samples (90%) are suitable for drinking as they have a salinity as well as nitrite, nitrate, phosphate and trace constituents less than the permissible limits as well as their low contents from faecal Coliforms. The rest of the groundwater samples (10%) are unsuitable for drinking as they have nitrite, nitrate, phosphate and trace constituents higher than the permissible limits as well as their high contents from faecal Coliforms.
