Riverbank filtration (RBF) is a process in which ri ver water is induced to flow through riverbed soils to pumping wells located on the banks. During this passage through the river bed and aquifer, dissolved and suspended contaminants as well as pat hogens are removed. In Upper Egypt, there is interesting in implementat ion of RBF because it has the potential to replace the current bad qualit y groundwater wells. In this study, a pilot studied site consisting of three handpumps installed about 8 m from a main canal was monitored. These ha ndpumps are used to supply potable water for private houses, Qena Go vernorate, Upper Egypt. Water samples from these handpumps, main can al, and municipal groundwater wells were examined. Quality measuremen ts were carried out. The results of these bank handpumps were compa red with those of canal and municipal groundwater wells. Phiso-chemic al quality of handpumps water is acceptable for drinking. There i s a caution about the microbial quality of produced water. The cost of ap plying RBF technique is less than traditional surface water or groundwat er treatment plant. Results of this pilot-scale site showed the effectiveness of RBF as a suitable method in Upper Egypt with low cost. |
