Water used for electric power production and different purposes nowadays in Egypt is from traditional sources like the Nile River and non-traditional sources such as seawater, excessively hard or brackish groundwater, poor quality surface waters, and wastewater. All these sources commonly require treatment with high-quality technologies before use. In the area of the West-Assiut Combined Cycle Power Plant (WACCPP), in Upper Egypt, groundwater is used as the source for demineralized water production for this power plant and it is used in other applications as well. In this paper, the quality of this groundwater and its suitability for different purposes are examined. Many chemical properties were examined such as corrosive ratio, water action according to the relation between pH and alkalinity, Kelly’s ratio, sodium absorption ratio, soluble sodium percent, the relation between EC and Na %, residual sodium carbonate, permeability index, potential salinity, magnesium adsorption ratio. The water pollution index rating scale was calculated for evaluating the water suitability for different purposes. Results showed that water is unsuitable for most purposes, and hence, polluted water is used in WACCPP.

如今，埃及用于电力生产和不同用途的水来自尼罗河等传统来源，以及海水，过硬或咸淡的地下水，劣质的地表水和废水等非传统来源。在使用之前，所有这些来源通常都需要使用高质量技术进行处理。在上埃及的西阿西乌特联合循环发电厂（WACCPP）地区，地下水被用作该发电厂生产软化水的水源，也被用于其他应用。在本文中，研究了该地下水的质量及其在不同目的下的适用性。根据pH与碱度之间的关系，凯利比，钠吸收率，可溶性钠含量，EC与Na％的关系，残留碳酸钠，渗透率指数，势盐度，镁吸附率。计算水污染指数等级量表，以评估水在不同目的下的适用性。结果表明水不适合大多数用途，因此WACCPP使用了污水。
