| Abstract | ||||
| Riverbank filtration is carried out at natural conditions and may occur by lowering the groundwater stream under the surface water levels either by hydraulic boundaries such as a bank of channels or by groundwater abstraction at pumping wells. In addition, the mixing of the infiltrated river water with groundwater at the pumping outlet well and the bank filtrate's retention time have been studied and identified as one of the critical parameters that determine the efficiency of riverbank filtration and water quality. RBF water results of pH, conductivity, TDS, hardness, color, alkalinity, nitrate, nitrite, phosphate, silica, sulphate, chloride, and turbidity were complying with The Egyptian Ministry of Health and WHO guidelines. The present study showed that groundwater's iron and manganese data in the study region did not comply with Egyptian regulation (Fe more than 0.3 mg/l and Mn more than 0.4 mg/l). The river surface water quality results did not comply with Egyptian regulation in some parameters, such as microbiological parameters (total bacterial count more than 5000 CFU/ml). The examination of river surface water samples was positive in total coliform fecal coliform examination. The study has shown that the water quality results from the RBF water had high water quality, especially in values of Fe & Mn and also microbiological parameters. The correlation coefficient between DOC recorded, and DOC estimated was very strong (r was 0.94). | ||||
