After Nile water, Groundwater is the major water resources in Dayrout, Upper Egypt. So, checking groundwater quality is of a high priority for insuring health. In this study, water quality index (WQI), its correlation with the water quality parameters, and Gibbs and Piper diagrams were used to analyze groundwater suitability for drinking and irrigation purposes. Groundwater levels fluctuation with physiochemical parameters of thirty boreholes are recorded and analyzed from January to August 2016. The boreholes water levels show seasonal variations of about 2.3 m. (WQI) values showed low groundwater quality for drinking within urban area west of the Ibrahimmia Canal. Whereas in the east of Ibrahimmia Canal has good (WQI) values but needs disinfection, within drinking limits. All the boreholes show good indices for irrigation water quality. Gibbs and Piper diagrams are presented with major samples falling into rock dominance and belonging respectively to hydro-geochemical facies of Mg Ca HCO₃.

继尼罗河水之后，地下水是上埃及代罗特的主要水资源。因此，检查地下水质量对于确保健康至关重要。在这项研究中，使用水质指数（WQI），其与水质参数的相关性以及Gibbs和Piper图来分析地下水是否适合饮用和灌溉。记录并分析了2016年1月至2016年8月地下水水位随理化参数的波动情况。该水位的季节性变化约为2.3 m。（WQI）值表明，易卜拉欣运河以西的市区内饮用的地下水水质较低。易卜拉欣运河的东部（WQI）值很高，但需要在饮用限制范围内进行消毒。所有钻孔均显示出良好的灌溉水质指标。₃。
