In the present work 20hand-dugged and Artesian wells were chossefrom Hamad Aga Al-Tathani and Hateen dwelling quarter for studyingwater quality .Samples of water were analyzed for determination of thefollowing parameters (Electrical conductivity, Total hardness, Sulfate,Chloride ,Nitrate, Calcium, Magnesium, Sodium and Potassium ).The results reveales that water of all wells were classified as hard tovery hard and also water are not suitable for drinking and industrial uses.According to classification system for irrigations water ,All samples(% 1 00) in Hateen region were classified as C3-S 1 category while those ofHamad Aga Al-Tathani were classified as followes C3-S 1%40,C4-Sl %40 ,C3-S2 %10 ,C4-S2%10.Sodicity percentages , in bothregions, were less than %70.
