This work is aimed at assessing the groundwater quality of the quaternary aquifer in reclaimed areas at northwestern El–Minya governorate – Egypt, using the water quality index for sustainable development. 32 water samples representing the surface water and groundwater samples were collected. The hydrochemical characteristics, geochemical classification, geochemical evolution and statistical analyses as well as groundwater quality were done.The obtained results indicate that; the total dissolved solids increases in the south and north directions and confirm that there are two sources of recharge for the Pleistocene aquifer groundwater, and the recharge from the irrigation canals is occurring in a certain distance range from 8 to 15km. The water quality index model indicates that the majority of the groundwater samples is unsuitable for human drinking; most of groundwater samples can be used for irrigation. Also, most of the lands are suitable for plants with high salt tolerance
