|Title||Assessment of Groundwater Quality Using Multivariate and Spatial Analyses in Gaza Governorate-Palestine|
|Title in Arabic||تقييم جودة المياه الجوفية باستخدام تحليل متعدد المتغيرات و التحليل المكاني في محافظة غزة -فلسطين|
Gaza strip suffer from the deteriorating of ground water in both quality and quantity, Groundwater is one of the most precious natural resources in the Gaza Strip as it is the only source of drinking water for the majority of the population, Nowadays There is a water crisis in the Strip. Groundwater contamination has become a major concern in the recent years. This study conducts a holistic assessment of the quality of groundwater resource in Gaza by using multivariate and spatial techniques. The assessment begins by Using R mode Factor analysis in order to extract factors and Cluster analysis to detect spatial similarity among sampling sites. Last GIS techniques is used to conduct water quality index (WQI).WQI classifying groundwater in a manner that can be comprehensive, clearly communicated and in an easily understood format. The R mode factor analysis revealed three dominant factors affect the hydrochemistry of water; the biggest factor with 64 % of variance is due to seawater intrusion. The cluster analysis distinguishes three main spatial clusters but the three clusters have values exceeded the guidelines of World Health organization (WHO) in different levels for each cluster. The value of Ground Water Quality Index is between 43 % and 63 %, this indicates that the overall quality of the water in the study area is extremely low. The narrow range of the indicator shows that the quality in the area is close to each other. One of the important recommendations of the study is to use GIS tools and its applications in producing maps to communicate our tragic water situation in the governorate for the world. Also Water quality indexes should be used in automated or manual way in order to understand the overall water quality.
