Abstract
The results of chemical analysis of four drinking waters from the Khaybar village, SW Saudi Arabia are presented. Four main water-wells in the Khaybar village were investigated. The Khaybar ground water is clear without odor but its taste differs according to the amount of total dissolved solids (T.D.S.). The pH values of such water are slightly alkaline. T.D.S. of the Khaybar water is higher than the Saudi highest desired level, but it is generally within the Saudi maximum permissible level. Good drinking quality water can be found in Al Mazaab and Al Tilah water-wells in the Khaybar village. The other two water-wells can be used for irrigation purposes only. The geological features of the Khaybar area suggest a meteoric origin for the Khaybar groundwater which has been stored in the fractured metamorphic and igneous rocks and in alluvial deposits.
