摘要：The main objective of this study was to assess! the quality of groundwater for irrigation! atWadi Almawaheb and Qa,a Asawad, in Dhamar city-Yemen, where the study was conductedin May 2016, Thirty Six groundwater samples were collected from different wells of thestudy area for the physico-chemical analysis. The results revealed that Potential Hydrogen(pH) of groundwater samples ranged from 6.7 to 8.6, the Electrical Conductivity (EC)ranged from 380-6327 μS/cm, the Total Hardness (TH) from 59.88 to 2224 mg.L-1 andSodium Adsorption Ratio (SAR) 0.54-7.1. The Water quality was classified according toUSDA and FAO systems (Guides). According to USSL 1954, the classes were C2-S1, C2-S2, C3-S1, C4-S1, and C4-S2 with 62%, 3%, 22 %, 8% and 5% of the wells, respectively.Based on FAO 1985, the classes were severing problem, slight-moderate and none problemand according to FAO 1992, they were moderate saline water, primary drainage water andgroundwater. However, according to the above mentioned classification systems, there areno risk for SAR to affect soil permeability. A various physicochemical parameters ofgroundwater have been studied and analyzed by calculating the correlation coefficients andprinciple component analysis (PCA) between them. A chemical and physical analysisshowed that there is a significant difference among the types of used water in some chemicalproperties. The results revealed that all water samples analyzed were very suitable forirrigation except two samples that have a highly saline which will effect on planted crops.
