| Abstract | ||
| The al-Arish area occupies part of the northwest corner of the Sinai Peninsula, representing an important region for Egypt's development. Rapid population increase, economic activities, and climate change affect groundwater resources, which are considered the main resource used for drinking, domestic, and agricultural purposes in this region. This study evaluates the quality of groundwater for drinking and irrigation purposes. Fourteen groundwater samples were collected, analyzed for different physicochemical parameters, evaluated, and compared to WHO standards, and maps for their spatial distribution were constructed using ArcGIS 10.4.1 software. The Water Quality Index is calculated showing an average of 54.13 for the area representing poor water quality. The water quality is classified as good, poor, and very poor in 71%, 14.5%, and 14.5% of the samples. SAR, Na%, and RSC measures were employed to assess the suitability of groundwater for irrigation purposes. According to SAR, 78.6 % of the samples are Good for irrigation. Na% classification indicates Suitable water for irrigation, except for one sample only. The results of RSC showed that all the groundwater samples are Suitable for irrigation. The Piper and USSL analyses confirmed important mineralization and salinity hazards due to seawater intrusion due to the nearness of the study area to the Mediterranean Sea and the overexploitation of aquifers. The study highlighted the need for sustainable water management plans, advanced irrigation methods, and governmental efforts | ||
