| Abstract | ||||
| The present study focused on assessing the quality of groundwater of the Quaternary aquifer in Wadi Qena Basin to deduce its suitability for different purposes according to the World Health Organization and Egyptian standards. Groundwater samples are collected from twenty three water points and analyzed to determine physicochemical parameters. Two effective techniques are used to develop the assessment of groundwater quality in the concerned aquifer; Groundwater Quality Information Mapping and Water Quality Index Estimation and mapping. Geographic Information System (GIS) was used to establish the integration of attribute data base and spatial data base for the studied aquifer. Therefore, by using GIS Tools; spatial interpolation Inverse Distance Weighted (IDW) as well as Reclassify and Weight Overlay methods are carried out to generate Water Quality Information map for the concerned aquifer. The Water Quality Index (WQI) estimation and mapping is used to generate WQI map by using GIS spatial IDW method. The obtained maps delineated the groundwater in studied aquifer into zones according to its suitability for human consumption. These maps revealed congruent results, where most of groundwater in this aquifer exists in the Not-suitable zone for drinking purposes however; it is suitable for irrigation purposes. The best sites for groundwater extractions from the Quaternary aquifer in Wadi Qena Basin are detected at the eastern side of the study area; where the groundwater exists in the Potable zone which suitable for drinking and human consumption. The spatial data base constructed in GIS technique is helpful for monitoring and managing groundwater quality of the Quaternary aquifer in the study area. | ||||
